Innovation In Science Pursuit For Inspired Research 

(INSPIRE) 

Innovation in Science Pursuit for Inspired Research (INSPIRE) is a National Programme 

implemented by the Ministry for attraction of talent amongst students to study science and 

pursue career with research. 

The basic objective of the programme is to communicate to the youth of the country the 

excitement of creative pursuit of science, attract talent to the study of science at an early age and 

thus build the required critical human resource pool for strengthening and expanding the 

science and technology system and R&D base. 

The programme was launched by the Hon’ble Prime Minister on 13th December 2008. The 

implementation started during 2009-10. 

INSPIRE Programme covers students in the age group 10-32 years, and has five components: 

INSPIRE Award (for 10-15 age group), INSPIRE Internship at a science camp with opportunity 

for interaction with global science leaders (for 16-17 age group), INSPIRE Scholarship for 

Higher Education (SHE) @ Rs 80000/ per year for continuing education at B.Sc. and M.Sc. levels 

(for 17-22 age group), INSPIRE Fellowship for doctoral research (for 22-27 age group) and 

INSPIRE faculty for assured career opportunity (for 27-32 age group). 

In so far as INSPIRE Award component is concerned, nearly 6.75 lakh INSPIRE Awards have 

been sanctioned till date. About 48% of the awardees are girls and 25% SCs/STs. As on date, an 

amount of Rs.432 crore has been spent so far on the scheme, out of which Rs. 85.85 crore has 

been released to the States/UTs to meet the expenditure in connection with District Level 

Exhibition and Project Competitions (DLEPCs)/State Level Exhibition and Project Competitions 

(SLEPCs)/National Level Exhibition and Project Competitions (NLEPC). Under the INSPIRE 

Internship, as on date about 500 Science Camps have been held covering about 1.25 lakh 

students in the age group of 16-17 years, 30 Nobel Laureates and 3500 resource persons 

participated in these camps. About 15000 scholarships for students in the age group of 17-22 

years have been given and about 1900 INSPIRE Fellows in the age group of 22-27 years have 

been enrolled so far. Finally, under the Faculty Award for Assured Career, 177 individuals have 

been awarded inspire faculty fellowship for initiating research work in various universities/ 

academic institutions/ laboratories in the country. 

The first component, viz INSPIRE Award, is implemented centrally through the States/UTs. 

Under this scheme, during the five year period two students are selected from each school of the

country for an INSPIRE Award of Rs.5000/- each for preparing a Science Project/Model. These 

awardees, who are students from classes 6th to 10th, then participate in a three tier competition: 

District, State and National Level. The projects exhibited are evaluated by a jury of experts. All 

the 28 states and 7 UTs are participating in the scheme. The scheme will continue in the 12th 

Five Year Plan, possibly with an extended coverage, under which a proposal to sanction one 

Award per school per year is under consideration of the Government. 

Merit based selection of students for INSPIRE Awards is done by the Head Master/Head 

Mistress/Principal of each school, who is required to send nomination of best children, having 

aptitude for science, with all relevant details, to the District Education Authorities, who will 

send these to DST through State Education Authorities. All schools in the country including 

private schools, are eligible to participate in the scheme. 

As on date, more than 6.75 lakh Awards have been sanctioned under the scheme, more than 5 

lakh awardees have participated in the DLEPCs, and about 30000 best entries of DLEPC have 

participated in the SLEPCs. 688 science projects/models selected from SLEPCs participated in 

the Ist NLEPC held at Delhi during 14-16 August, 2011. Her Excellency, the President of India 

was the Chief Guest in the Award Ceremony held on August 16, 2011. Out of the 688 projects 

which participated in the 1st NLEPC held during August 2011, 85 have been shortlisted by the 

Patent Facilitating Centre of TIFAC for detailed examination for possible patenting in some 

cases. More than 1000 science projects/models are expected to participate in the 2nd NLEPC 

scheduled at Delhi from 21-23 October 2012.

DOMESTIC 

WIND POWER 

GENERATOR 

The project is made to create an awareness on the need to harness 

and conserve the natural resources which are God's gift to man. The 

project includes a domestic wind power generator and a rain water 

sump. 

Domestic Wind Power Generator 

The Harnessing of wind energy to produce power has long been used 

as a source of energy. Eg. sailing ships, windmills. Wind power is 

inexhaustible non-polluting, renewable, free and non-depleting and 

can be used to generate electric power at low cost. This domestic 

device converts wind energy to electrical energy. However it is only 

an alternative source of energy to complement hydroelectric power 

and thermal power. 

The device is a vertical axis windmill. The axle goes down to the 

bottom where it is joined on to a pulley and that rotates the dynamo 

in the gear box. The gears increase the rotations and as the dynamo 

turns it produces electricity. The traditional and the conventional 

wind mills are in fixed positions to the direction of the wind, where 

as the vertical axis windmill is very practical and conventional 

windmill, as this will function efficiently in every direction of the 

wind. It is an effective and efficient device to harness wind power. 

Rain Water Sump 

Water is used in everything people do; from drinking to washing, 

from irrigation to industrial activities, from cooling to power 

generation and from recreation to waste disposal. It is indeed the 

lifeblood of civilisation and development. 

A precious source that water is, its availability has become scarce, 

hence the need for its conservation. The rain water sump is a simple 

way to conserve this precious resource. The rain water from rooftops 

which is commonly let off into drains can be utilised for various 

purposes. The outlets from the rooftops are connected through a 

pipe to a storage tank after filtering and disinfecting. In houses and 

apartments there is sufficient open place for water collection and 

storage. The rain water sump will help to complement the increasing 

demand in times of uncertain rainfall. 

Water is a community resource and needs community participation 

to conserve it. Let us join hands and conserve this precious resource. 

Let's care for it before it becomes rare.

FIRE PROOF HUT 

Required items: copper wire adjusted for hut, dried grass, 

side wall of the hut built with mud, sand. 

Just boil the dried grass and dry it in cool places. After it 

cool it can covered with copper wire. 

Observation and gain: 

It can be built with low cost. It helps for poor people. 

While covering the grass with copper wire it can't burn 

because of absence of oxygen. The roof of hut can revoke 

easily and construct easily.

POWER GENERATION 

WITH SEA WATER OR 

SALT WATER 

1. Sea water is very salty, but this water can be used to 

generate electrical energy. In this project, I will 

demonstrate how we can use the sea water for power 

generation and for drinking. 

2. The main principle used here is electrode ionisation, so 

I have used copper plate and zinc plate wound with 

magnesium wire as two electrodes. The cathode releases 

electrons and the ions. And the ions include are Na+, Cl- , 

Zn+ ,Mg+ , Cl- . 

3. Now a days the power is very valuable for our day to 

day needs and for the industries. So this power(current) is 

very cheap and is of low cost, which can be used by 

people living in the coastal areas and other parts of the 

country.

SAVING OF 

GROUND WATER 

IN AGRILCULTURE 

Aim: saving of ground water in agriculture 

Explanation; To save the ground water in agriculture 

purpose. We have to take a pipe with readings as “cm”. to 

know the level of water in agriculture fields. 

We have to dig the ground in the field and insert the pipe. 

When we pour the water enter into the pipes. In which 

we can identify the level of water. The farmers exactly 

don't know how much quantity of water required for the 

plant at different stages. 

Ex: at the sowing state of plant it absorbs only 3 to 4 cm of 

water. We can identify the level of water by using this 

pipe. so farmer know that how much quantity of water 

require for the plant at different stages 

Uses; 1 stop the florosis in Nalgonda District 

2. save ground water & electricity 

3 stop the green house effect 

4 global warming

GEOTHERMAL 

ENERGY 

Geothermal energy is the thermal energy generated and 

stored in the earth. Thermal energy is the energy that 

temperature of matter. this energy of the earths crust bring 

inates from the formation of the earth and radioactive 

decay of mineral (80%). The temperature of the core is 

(6000c). which drives the continuous conduction of heat 

to the topper layers. we use hot dry rock. Rocks with poor 

permeability still can be a prospective sources for 

producing the electricity. The rocks are fractured using 

hot pressurised water. when the volume is sufficient 

another hole called production well is dug. When water is 

injected it gets heated up and converts into vapour which 

used to rotate turbines which into produce electricity.

BANANA STEM 

FIBER COVERS 

In our daily life for every need we are using polithin 

covers. This is the known fact to every one. These covers 

conn't mix in the earth even after 100 years. If any one 

can store the food in the polithene covers it caused the 

dangerous “cancer”. 

So that in the place of polythene covers should use other 

alternatives which available plenty in the nature 

resources. One of them is BANANA STEM TRUNK 

(FIBER) 

Process of design: 

1. Firstly we should procure the pieces of banana tree 

trunk. 

2. for every 1 kg pieces, 10 gr of NaOh should be mixed 

3. Heated (cook) in the water for the 30 min. 

4. Later it should be grinded. 

5. And that mixture on the iron mesh and should place in 

the dry place or sun rise one or two days. 

After that we can make use it to make covers and roaps 

etc.

TSUNAMI 

WARNING 

SYSTEM 

Farmers in and around our village cultivate the cotton and other 

crops. They usually use large amount of insecticides to destroy 

(eradicate) the pests and insects. Maximum percentage of 

insecticides reach destination other than the target species like 

harmless organisms. They also pollute air, water, soil, food grains 

etc; 

They show effect on farmers friendly insects, birds and other 

harmless organisms. These are all play the major role in controlling 

the harmful insects and pests. 

Enormous usage of chemicals has been developed resistance 

in insects to chemicals to eradicate them. Prolonged usage of 

insecticides make the land unfit for cultivation and also show effect 

on ecological balance. Chemicals induce bad effects on the health of 

man and other animals. 

After realizing the problems posed by chemical control 

methods effects were made to study the way the nature controls 

these insects and pests such methods are called biological methods 

of pest control. 

Biological control is a type of control in which harmful 

organisms are destroyed by using their own natural enemies and by 

using other methods. 

BIOLOGICAL METHODS: 

1. By using predators: the habitation can be provided for spiders, 

birds, wasps etc. By arranging heaps of dried leaves and twigs, bird 

posts, planting plants which bear yellow colour flowers in the crops. 

2. By arranging yellow colour insect trap boards: By arranging 

yellow colour trap boards (for 4 to 5 per acre) white mosquitoes 

which destroy the tomato and cotton crops are to be attracted. 

3. By using a light traps: milk white or yellow colour bulbs are 

arranged in the crop between 7 pm to 10 pm, mosquitoes and other 

moths are attracted to these lights which were collected in the 

containers arranged at the bottom of the lights. 

4. using of pheromone traps: male species of insects get the smell of 

pheromones then they are attracted to the lures and trapped. 

5. using of bio insecticides: with the use of bio insecticides like 

green chilli solution, garlic solution, neem oil, NPV solution etc., 

harmful insects can be controlled.

TSUNAMI WARNING SYSTEM 

Tsunami is Japanese word. Tsunami is powerful series of waves 

caused by a disturbance under sea. 

If we look into history of Tsunami we cannot guess damage by 

the Tsunami. Eg: In year 29.12.2004 Tsunami placed Indonesia, 

Srilanka, India Malasia & Thailand. 

So, the need of Tsunami warning system is to detect Tsunami 

in advance to prevent the loss of life and damage. Main cause 

of Tsunami is earth quack. But other causes are Land Slides, 

Volcanoes and comet hitting the sea. 

Tsunami travels at between 500 to 1000 km/hour. Seismic 

waves of earth quake travels speed of 14,400 km/hr. Due to less 

speed this only early Tsunami warning is possible. 

Dart System: This is one of the most advanced Tsunami 

warning systems. DART means deep ocean Assessment and 

reporting of Tsunami. This involves 5 components. 

1) Sea floor bottom Pressure recording Package: It consists of 

one CPU, Battery, Sensor, Anchors, One acoustic transducer 

the function of this system is to detect the change in temp and 

pressure under water. 

2) The Surface buoy: It is floating device. It has one acoustics 

transducer, battery, iridium and GPS antenna and big anchor. 

Due to the anchor buoy remains stationary. 

3) Radar: It is an electronic device. It helps us to detect 

Tsunami it can give the information about Tsunami before 45 

min to reach at the Tsunami. It sends signals to iridium 

satellite. 

4) Iridium satellite: Iridium satellite is a group of satellites to 

providing voice and date coverage to satellite cell phones. It is 

very helpful measure to detect Tsunami. It sends data to tower. 

5) Tower: It receiving signals from Satellite and transmits to 

ground station.

called Home Security Robot is created to detect any fire or 

some smoke which is harmful it gives a buzzer which is 

loud by this we can stop the fire accidents before it 

destroy.

WORKING PRINCIPLE 

OF CELL PHONE 

When a person talks on cellular phone, the voice message 

get converted into radio waves. The radio waves ravel 

through air until they reach a base station close by the 

base station send the call across the communication 

network after which the call reaches the intend receiver. 

A base station in the vicinity of the mobile phone being 

called sends radio awes for the receivers device to detect 

them. The mobile phone of the receiver converts the 

signals into voice and the phone call is made.

RECHARGE ABILITY 

OF WATER 

Even with a small quantity of water solves many of our 

water related problems. In summer we eagerly waiting for 

monsoons to get rain to solve our water related problems. 

But in rainy season we are wasting the runoff water, 

which is plenty in rainy season. Again in summer we 

depend on mobile water torrks. 90% water rain water 

flows towards the sea and join in it. If we cease of that 

runoff water no barren lands and thirsty voices are 

observed. The theme “ Harvesting of Rain water” improves 

underground water and solves related problems. Through 

this project we want to explain – Importance of water, how 

are can harvest rain water and how we can we improve 

underground water. .

BOTANICAL PESTICIDES 

AND INSECTICIDES 

IN AGRICULTURE 

Title of the Study :- “Botanical Pesticides and insecticides in 

Agriculture”. 

Objectives of the Study :- 1. Promoting eco- friendly 

Botanical Pesticides in agriculture 

2. Bringing awareness about non – chemical organic farming. 

Introduction:- The high intensity of Chemical Pesticides 

application has become a serious cause of concern in recent 

years. Damage caused by chemical pesticides to the 

environment, animal & human health is evident. In the 

circumstances, there is a growing need to promote the use of 

alternative methods of crop protection such as “Botanical 

Pesticides” – which are environmentally friendly. 

Botanical pesticides and insecticides are derivates of plants 

and herbs, which can destroy the pests damaging agricultural 

crops. 

Advantages of Botanical Pesticides : 

1. Eco- Friendly, non-pollutant, not harmful to natural 

enemies of pests in nature. 

2. Reduces chemical pesticides usage and not harmful even 

on repeated application. 

3. No serious residual effect on man and animals and not 

dangerous if it is adverently consumed also. 

4. Low –cost technology, convenient, easy and available 

locally for small scale farmers. 

Materials & Methods of the Project :- Above 30 species of 

planets with pesticidal properties, solutions of some plant 

extracts, charts showing planets and their action on various 

pests and preparation methods of various botanical 

pesticides. Picture of 1) a) Consumption of chemical 

pesticides in India, b) Why no to chemical pesticides, c) 

adverse effects of chemical pesticides on man 2) a) causes for 

limited usage of Biological control methods b) IPM 

(Integrated pest Management) policy.

SIGNIFICATION OF 

MEDICINAL PLANTS 

In our daily life human being are suffering from so many 

disease. But some disease are not cure with medicines. 

Therefore here I have made an attempt to prepare for 

medicines by the collection of medicinal plants and their 

products. Which can be used as an alternative to English 

medicines by using low cost and without side effects. 

Hence this concept will be encourage are properly develop 

in the rural areas for better health. 

Based on the principal described above number of 

medicinal plants are collected by the team members with 

the help of guide teacher are cooperation with villagers. 

These plants are preserved with herbarium sheets as well 

as photography. The Homeopathy medicines prepared 

according to the ancestors given principal the cumulative 

output of the medical plants be used for as daily life with 

out side effects.

WINDMILL 

WINDMILL 

INTRODUCTION: Wind Mill is the model. It is used to 

produce the electricity. Electricity can be produced by 

atomic energy, thermal hydro seam etc., perhaps 

electricity is jnot sufficiently obtained. So wind is also a 

form of energy with this also we can produce the 

electricity. 

Materials used: Turbine, shaft, AC Dynamo, Voltmeter, 

LED bulb, wire, fan plastics pipe, screws. 

Procedure: 

1. setup the wind mill using turbine, shaft dynamo, fixed 

to 2 ft plastic pipe with the help of screws 

2. connect the AC Dynamo to bulb and Volt meter with the 

wire 

3. put the fan (running with electricity) and turbine,. The 

turbine rotates on it's axis fastly against the direction of 

the fan. 

4 Turbine connect to the AC Dynamo with this rotation 

Electricity produced there can be seen through bulb and 

the volt meter. Here mechanical energy produced in the 

turbine converts electrical energy.

TRAIN DISASTER 

A 'great' number of accidents are being experienced by 

'Trains' Due to floods and removal of tracks. 

The 'National Crime' Records Bureau, Which gathers the 

causes of fatalities across India says 25,705, people in total 

died on the railways in '2009'. This data is not broken 

down. 

India's Worst Rail accident' was in 1981 when a trail 

plunged into a river in the eastern state of Bihar killing an 

estimated 860 people. Due to improper maintenance of 

rail tracks, and negligence by the staff these kinds of 

accidents are going to take place in our country. 

In order o avoid these type of train accident. I have 

designed by exhibit. 

To Avoid train accident due to floods National calamities. 

The working mechanism to avoid train accident due to 

floods is by giving alarm to created awareness in order to 

stop the train. It works by closing the circuit. 

A pole is fixed to the river bed to which a fixed coil and 

floating coil is attached. Fixed coil is fixed near the danger 

level. 

(floating) with the rise in water level. 

The floating coil is also rises along water..

BIO INPUT GOOD SUBSTITUTE 

FOR FARM YARD MANURES 

(FYM) 

Plant is incapable to take up nitrogen directly from 

atmosphere even though it contains about 77% nitrogen. 

Some of the bacteria living in soil fix atmospheric 

nitrogen to make it available for higher plants. Similarly, 

soil contains significant amount of phosphorous, but in 

unavailable form. Various chemical and biochemical 

processes make this nutrient available to plant. Thus 

status of various nutrient cycling processes indicate the 

health status of soil. 

Due to poor organic fertilizers in the soil enrichment of 

soil with organic matter is an uphill task for the farmers 

due to non availability of organic fertilizers especially 

Farm Yard Manures (FYM) . So we selected a project on 

“BIO-INPUST GOOD SUBSTITUTE FOR FYM”. 

To study the importance of bio fertilizers we conducted a 

simple experiment on different places and paddy with 

different mixtures of organic, inorganic and bio fertilizers 

(Rizobium, PSM,PMB and Azospirillum). We have 

surveyed 40 formers about organic farminc and on Bio- 

Fertilizers. 

We observed average percentage of seed germination. 

Percentage of seed germination is more in Bio Fertilizers 

+NPKS than in Farm Yard Manure. We observed the 

average length of the short on 10th day 20th day,30th day 

and 40th day. Average length of shoot is more in Bio- 

Fertilizers+ NPKS THAN IN Farm Yard Manure. 

Therefore it is advocated to farmers that in the event of 

non-availability of FYM, Rhyzobium,PSB,PMB and 

Azospirrullum can be applied along with the 

recommended dose of NPKS under rain fed situations. 

However application of Farm Yard Manure should be done 

in the next year (one ear Bio-Biofertilizers followed by 

FYM in the next ear) for soil fertility build up.

number of branches and meets the sea. This is a marshy 

tract, rich in life. 

Problems of Estuaries: Estuaries and life there are 

facing serious problems due to induatrial waster, 

agricultural waste and the wastes created by aqua farm 

and human activities. 

Toxins, carcinogenic agents, pathogens and 

eutrophication are destrouing the estuarine life 

Remedies: Remedies are suggested to deal with 

industrial waste, agricultural waste and human activities. 

They include proper disposal of industrial waste, using 

less chemical fertilisers and limited human activity.

PRODUCTION OF PETROL 

FROM WASTE PLASTIC 

Introduction : The plastic problem is certainly not going 

away. Many think that type of re-cycling is not a 

solution. But to Eradicate this problem we suggest a new 

process to convert the waste plastic into fuel. 

Process : This process starts by crushing the plastic into 

small pieces and than the crushed pieces will be dried by 

drier. The dried plastic will be sent extrusion machine 

where it will be melted. There will be three subfuels 

1. Solid fuel : Coke 

2. Liquid fuel : Combination of Gasoline, Kerosene, Diesel 

and lube oil. 

3. Gas fuel : LPG 

Then the three products are sent to pyrolosis chamber and 

then to distillation chamber where the different products 

are separated in the vacuum and all are converted into 

liquid state and are centrifuged and are filtered and are 

stored. The maximum reaction temperature is 350 

centigrade. There is total conversion of plastics into value 

fuel products. 

Advantages : By this process we can reduce the wastage of 

plastic and we can save our petroleum for longer period. 

The machine can convert to 2 LBS of plastic into a 

Quarter of oil of one K.W of power.

SYSTEM OF PURIFICATION OF 

SEWAGE AND PRODUCTION 

OF HYDRO ELECTRICITY 

The model we made is the system of purification of 

sewage and production of hydro electricity. We have 

arranged three containers in the ground for the 

purification process. The waste is collected into the first 

container and passes to the second container . There we 

have arranged filter paper and wood to stop waste dust 

particles and small pebbles . But the water contains 

inorganic bacteria. 

Then the water is passed into the third treater 

forcibly. Then the water falls on the turbines . Which was 

arranged in the third beater for the production hydro 

electricity. By using the dynamo and we can use the 

electricity for various purposes. In the third container to 

purify the water we have used sylurite (kcl) and 

bleaching powder instead of chlorine gas. Then the water 

is purified and the water can be used for various purposes

FOOT STEP POWER GENERATION 

SYSTEM FOR RURAL ENERGY 

APPLICATION TO RUN 

Introduction : Man has needed and used energy at an 

increasing rate for his sustenance and well being ever 

since he came on the earth a few million year ago. Due to 

this a lot of energy resources have been exhausted and 

wasted. 

Principle / Concept : In this project we are generating 

electrical power as non-conventional method by simply 

walking or running on the food step. 

Explanation : In this project conversion of the force 

energy into electrical energy. The control mechanism 

carries the piezo electric sensor. 

Analysis : Power generation we simply walking on the 

step. Power also generated by running or exercising on the 

step. No need fuel input. On -site power production 

circumvents transmission and distribution costs for the 

delivery of electricity. 

Conclusion : A new generation of high frequency linear 

array using 1-3 composite is described. A set of 

simulation tools has been carried out for modelling 

composite behaviour. This study demonstrates the 

possibility of manufacturing composite with higher 

frequency then currently done. Performances of this array 

could be considered as comfortable, regarding to current 

applications.

PREVENTION OF FIRE 

ACCIDENTS IN TRAIN 

AIM :- To prevent fire accidents in trains and save the 

lives of he passengers and protect railway (public) 

properties. 

Requirements :- 1) one 12v transformer, 2) two diods, two 

capacitors 100uf/25v 4) LEDs 5) two buzzers 6) one 7805 

regulator 7) one 12v relay 8) one switch 9) five n-p-n 

transistors 10) one electric board 11) one power card 12) 

one submersible 230v cooler pump 13) plastic pipe and 

plastic box. 

Process of working :- Generally in trains 110v power 

supply is there this power supply is connected with MCB 

(Master break down tipper). This MCB does not work 

effectively, because it functions only when high power 

supply passes through it. 

Then only it stops the power supply. So when the fire 

accidents take place there is no guarantee for stopping the 

power supply in the compartments. Therefore, we 

conducted a experiment, through the circuit, when ever 

the fire accidents take place. 

1. It stops power supply immediately in that compartment 

2. Through this circuit it gives buzzer sound and alerts the 

train driver and passengers to escape from the fire. 

3. Through this circuit automatically supplies water and 

stops fire in the compartment.

MANUFACTURE 

OF FUEL 

Introduction : At Present we are manufacturing fuels 

from crude oils only. We can also prepare fuels from waste 

plastic materials. This process is without environment 

pollution and less expensive. Waste plastic materials 

means plastic covers, papers, bottles, wires, plastic items, 

cans, foils, etc. these are non soluble in soil. 

Manufacture: manufacture of fuel process is very simple. 

Plastic will melt, but will not burn. After it has melted, it 

will start to melt and evaporate. These vapours are sent 

through a cooling pipe and when cooled the vapour will 

condensed to a liquid and some of the vapour with 

shortened hydro carbon lengths will remain as a gas. If the 

cooling of cooling tube is sufficient there will be no fuel in 

the bubbler and this will float above the water and can be 

poured off. 

Procedure: we need to heat the plastic slowly to about 

350°C degrees and just wait. Our device has a capacity of 

50 lts and coin hold about 30 30kg of shredded plastic. 

This makes a liquid fuel and it works for diesel engines 

just fine that has already been tested. 

Conclusion: If co2 increases air pollution, water pollution 

starts. It causes was disease starts in human beings, 

decrease the rains and totally global warming begins.Our 

project is 100% without pollution ie., manufacture of fuel 

b waster plastic materials.

USE OF WORN OUT 

TUBE LIGHT 

The worn out tube light can be lit up by using some low 

cost electrical instruments like turn 474k pf's four 4007 

diodes, three conductor spring wires and one no-2 sleeves. 

This can be lit in low voltage current also. If we use this 

system we can save the electricity bill the guarantee we 

give for this system is few grass. This method can be used 

for lighting the street lights, lighting etc. If government 

implements this method much amount can be saved and 

use can donate this to the formers of our country and take 

India bright future.

SOLAR ROOM COOLER 

The model which is describe here is my solar room cooler. 

The solar cooler as it's name implies is an application of 

nonconventional energy his solar energy. This mechanical 

device shows how the temperature of air in a room can be 

lowered by the direct use of solar energy. 

The vary idea of the model comes from how the water 

vapour arising out of water pools is becoming clouds at 

low pressure zone. It is actually based on the principle 

vouls Thomson effect. If a highly compressed gas is being 

continuously forced at constant pressure through a small 

sparture or through a partly abstracted passage suffers a 

volume expansion. As a result of Joul Thompson 

expansion the temperature of the gas decreases. The 

decrease of temperature is proportional to the pressure 

difference at the ends of small aperture. 

The model is very simple. The material used for the 

construction of the model are 1) a carbon coated tin plate 

2)Two glass jar 3)Glass tubes 4) Rubber Tubes 5) Two 

Thermometers 6) A Manometer 7) A Source of Light e.g. 

Table Lamp. 

This solar room cooler can be prepared in a big size and 

can be used in houses. The glass structure is to be kept 

either on the sunshade or on the roof. Manometer shall be 

kept inside the room. Observe the pressure created in the 

manometer and cool the room temperature by loosing the 

clamp.

VIDYUTH VIGNYANAM – VINODAM 

Introduction :- To identify the conductors and nonconductors 

of current in all goods land 

biological things of environment prevention from 

unforeseen shocks. 

Principle :- Identify the conductors and non-conductors of 

current by converting alternate 

current (AC) to Direct Current (DC) Through sensors. 

Uses & Construction :- It is very difficult to make the 

students understand about the subject matter or current 

/electricity. So we developed a new method to teach 

electricity concepts with help of the project i.e. VIDYUTH- 

VIGNYAMAN - VINODAM. 

We can identify electric conductors a low voltage current 

without shot very speedily. We can also make the students 

to do this experiment to understand the concept easily. In 

addition that the students can understand that the living 

and nonliving cells also act as electric conductors. 

Apparently it is possible to make the students fear free 

from bad effects of electricity. The project is easy one and 

done by every one at their level. 

At first 230v transformer convert in to 12v AC. This AC 

voltage is attached to rectifiers. Then it converts to 12v 

pulse DC. When this DC is attached to capacitor it 

converts 12v pure DC. 

This pure DC voltage converted from 12 v to 7.5 v through 

regulators and attached to LED of 2.2 ohms with help of 

rectifiers. When current is connected from one point to 

another point through sensors, the transistor is charged. 

These transistor Q1, Q2 amply the signal and send to 

switching transistor Q3. This Q3 transistor pass the 

positive voltage from emitter through collector to LED. 

Then theLEDs glow.

DESERT – AN EVERLAST 

SOURCE FOR ENERGY 

Solar Thermal Energy is a carbon free renewable 

alternative energy for power generation. 

The benefits of solar power are compelling that no harm is 

done to the environment by burning of coal, o1, Natural 

gas or by spitting of Uranium to produce steam. It is 

produced solely by energy that comes from the sun. 

There are two main processes for generating energy from 

Sun. 

(a) Photo Voltaic 

(b) Concentrating solar Thermal 

Solar Thermal Technology is large scale power generating 

process when compared to photo voltaic. 

Method : Take a Parabolic troughs the in order to collect 

the sun radiation. Parabolic troughs power plants use a 

curved, Mirrored troughs which reflects the direct solar 

radiation on to a glass tube containing a fluid (also called 

a receiver absorber or Collector), Running the length of 

troughs positioned at the focal point of the reflector. 

Troughs is parabolic along one axis and linear in the 

orthogonal axis. For change of the daily position of the 

Sun. Perpendicular to the receiver, the trough tills East to 

West so that the direct radiation remains focussed on 

receiver. A fluid (are called heat transfer fluid, HTF) 

passes through the receiver and becomes very hot. The 

fluid containing the heat his transfer to a heat engine 

where about a third of the heat his converted to electricity 

. Heat in solar thermal system is guided five basic 

principles 1) Heat gain 2) He transfer 3) Heat storage 4) 

Heat Transport and 5) Heat Insulation. So the entire 

process consumes the habitat of deserts which becomes 

“ALILVE SOURCES”.

WASTE IS NOT WASTE 

Introduction : In our Surroundings we fine two major 

problems one is water scarcity and another is pollution by 

Garbage. To over come these problems a project. On 

“WASTE IS NOT WASTE” is prepared. The steps in the 

project are 1) Mulching 2) Terrace plantation 3) 

Preparation of gum by thermocoal. By these methods we 

can protect land, water and environment. 

Mulching :Mulch is marvelous ingredient protective cover 

placed on roots of the plant (or) germinated seeds. Mulch 

is primarily used as a soil conditioner. Fresh coloured 

organic mulch properly composted, reflects light and 

causes optimum temperature around the plant. Excessive 

application of mulch creates a breeding ground for insects 

and fungi. Our Projects results : Re-use of waste materials 

like waste from trees, waste rubber, plastic and kitchen 

waste as a mulch reduce environmental pollution. Organic 

mulch is inexpensive fertilizer. Effective use if much is 

good for vegetation and crops. Before mulching all waste 

is better to composted by earth works because it develops 

useful bacteria and makes soil porous. Hence it is 

supplement soil nutrient. But it is not recommended for 

water logged soils. High yield crops occur when drip 

irrigation is subjected under the thick layer of plastic 

mulch. 

Terrace plantation : Growing herbs vegetation and flower 

plants on the roof or Terrace of buildings and multistoried 

buildings. 

Results :- 1.We can grow sufficient leafy vegetables with 

Less water. 

2. By terrace plantation we can reduce interior 

temperature, power consumption and pollution.

FUTURE FUEL 

HYDROGEN GAS 

Hydrogen and Oxygen Gases (HHO) can be obtained from 

water through Electrolosis. Any substance is heated it 

decomposes. To Decompose any energy is needed. By 

sending Electricity through it can be decomposed into 

Oxygen and hydrogen Gases. 

MATERIALS USED : 

Electrolizer, Stainless steel water tank, Bubbler, Home 

Torch. 

WORKING : 

Water tank is filled with water Switch on the power water 

inters the electrolizer from water tank. So many electrodes 

are their in the electrolizer. Here water is divided into 

Hydrogen and oxygen gases. This gases again enter into 

the water tank as water is dencier than the gas, it reaches 

the top of the water tank through another tube and gas 

comes out from the flame torch. It burns when it is lit. 

Uses of Hydrogen and Oxygen Gas (Brown Gas) 

1. It can be used as cooking gas 

2. It can be used in vehicles as fuel 

3. It can be used in velding shops instooda oxyecitolyn. 

It is pollution free gas.

HYDRAULIC MACHINES 

My project demonstrates the principles behind working of 

hydraulic machines using 3 models. 

My first model demonstrates the basic principle 

underlying working of all hydraulic machines, namely, 

'Force that is applied at one point is transmitted to another 

point using a confined fluid.' 

My second model of a proclainer reiterates the same 

concept. It can lift a bucket of marbles and shift it to 

another place. The framework of this model has been 

made using 'Mechanix' engineering set (Zephyr Company; 

Mumbai) and is integrated with 3 sets of syringes and i.v. 

fluid tubing. One set of syringes facilitate horizontal 

motion; another set facilitate vertical motion and the third 

set operate a pincer that holds and releases weights. A 

mosaic toy board has been used to bring stability to this 

model. 

My third model of a 'hydraulic jack' is based on Pascal's 

law. It uses syringes of different crossection area for effort 

and load with the load syringe having higher cross-section 

area. So, force applied is multiplied by a factor equal to 

the ratio of cross – section areas of load and effort. A 

simple hydraulic jack made using two 5ml syringes, one 

50 ml syringe and 2 cycle ball-bearings is able to lift a load 

of 1.5kg. this model is assembled on a plastic rack using 

ie. fluid tubing and nylon thread.

WEALTH FROM WAVES 

TIDAL TREASURER 

Capacity to do work is known as Energy. Energy is 

available in many forms. Ex: Light, Chemical, Electrical, 

Heat, Mechanical, Kinetic, Potensial and Atom Power. 

Energy is measured in Jouls and Kilo Caleries. The 

amount of energy consumed by a person or society 

depends on the way people live. Ex: An America use 2.50 

Lakhs K.C. While Indian uses 20 to 30 thousands K.C. 

The Consumption continues like this, energy crices 

occures in 50 to 100 years. 

We get more energy from Coal, Petroleum and Natural 

Gas. But burning of fossil fules pollutes the atmosphere 

by increasing CO2 content. This causes Global Warming 

and acid rains. 

Now a days the entire India, facing the power cut 

problem due to non production or energy in sufficient 

quantity and mis utilisation of Energy. So, the project 

Tidal Energy is selected to depend on alternate sources of 

energy. 

Large amount of energy (kinetice energy) is stored in the 

waves especially seas. Special devices to made to rotate 

as the water proces through them by wave action. This is 

used to run turbines to generate energy. 

Use of tidal energy, is not polluting, Naturally occuring, 

cheaply available resources and Friendly to environment 

which will be available for centuries.

ENVIRONMENT EFFECT ON 

BIO – DIVERSITY AND 

CONSERVATION 

Environment effect on Bio diversity and Conservation :-. 

Habitat of the living organisms is called environment. 

All the living organisms (micro-organism, plants, animals) along 

with the human beings in the nature constitute bio diversity. 

Bio diversity extinct due to humanistic activities. 

The primary responsibility of the human being is to protect 

biodiversity. Because if the species extinct will not create by us. 

All the organisms have equal right to live in the environment along 

with the human being. 

So many species are extinct due to the following humanistic 

activities. 

1) Deforestation 2) Radiation 3) Industrialization 4) Hunting 5) 

Pollution 6) Forest fires (Natural Factor) etc. 

Bio diversity protects in two methods : 

(A) In-situ conservation : In this process organisms are protect in 

their natural habitat 

(B) Ex-situ conservation : Organisms are placed and protect in man 

made place away from 

their natural habitat. 

Ex : 1) Gene Banks 2) Tissue Culture, 3) Social Forestry 4) Cryo 

preservation 

Gene Banks :- Here we can protect the seeds of rare species 

Ex ; Co-Co, legumes etc... 

Tissue Culture :- In this process we can produce the complete plant 

by using, pollen grain, vegetative parts of plant in restricted 

conditions 

Social Forestry :- Which is produced by local people and the 

production will be shared to them. 

CRYO Preservation :- Here we can preserve the cells, sperms, ova, 

fetus of the animals at 196oC innitrogen solution. At this conditions 

cells will not damage for long time. The scientists of CCMB, 

Hyderabad developed / preserved some cells in this method, and 

said that we can nserve the extinct species gesmplasm and protect it 

from deletion.

RAIN WATER 

HARVESTING 

Water is one of the most important elements and no creature 

can survive without it. Human beings could not save and 

conserve water and its sources, probably because of its 

availability in abundance. The world is facing acute scarcity of 

water. It is said that if any world war happens it will be for 

water. The underground water level has gone very deep. The 

storage of water is not problematic only in our country but also 

at universal level. It is considering the problem; I selected this 

topic as the only source and awaring of people to use water in 

proper way. 

Structure of apparatus and activity:- Three pipelines are 

directed towards the ground from the roof which is as follows: 

1. One of the pipelines is directed into the percolation pit 

which is to increase the ground water level. 

2. One of the pipelines is directed towards filtering chamber 

which is connected to open wall which is used for drinking, 

kitchen and bathroom etc. purpose. 

3. One of the pipelines is directed towards the recharging well 

which is used for agricultural purpose. 

4. Then the rain water that falls on the roof travel through 

these pipelines enters into the different chambers. Thus the 

water is harvested, avoiding its loss as flow. 

Qualities:- This can be easily made in multistoried building 

and other houses so that water can be harvested and also the 

installation of these water reservoirs can be promoted in our 

locality in very easily and simple way. 

Cost:-Each model Rs 1500 to Rs 3000 

Conclusion:- The successful attempt of rain water harvesting 

will reduce the problem of scarcity of potable water. This 

presentation is based to find the solution of the above problem. 

This can be applied in villages and town and metropolitan 

cities. This will not only save the scarcity of water but it will 

also provide field for fisheries Makhana, gTrapa cultivation 

adding to economy of the people.

Aim:- To make the people aware about disaster and disaster which occurs 

in specific areas so that they can prepare themselves to minimize the 

effect of disaster. 

Principle :- To show the following disaster zones in map. 

1- Landslide Cause :- Earthquake, Deforestation, Excessive construction 

on slopes. 

Area :- Hillsides, valleys. 

2- Flood Cause :- Large volume of rainwater enters river channel, when 

a river becomes shallow due to deposition on its bed. 

Area:- Ganga-Brahmputra basin 

Brahmputra in Assam, Koshi in Bihar & Mahanadi in Orissa. 

3- Earthquake Cause :- Volcanic eruptions & displacement of plates. 

Area :- Foothills of Himalaya and Ganga-Brahmputra basin. 

4- Tsunami Cause :- Earthquakes, Volcanic eruptions, Water explosions & 

detonation of nuclear weapons. 

Area :- Coastal region. 

Required Apparatus :- 

I. LED bulbs 

II. Cardboards 

III. Wooden plyboard 

IV. Wires 

V. Batteries ( 9 V) 

VI. Resistance 

VII. Switches 

VIII. Decorative tapes 

Methodology :- LED bulbs are fitted in areas of disaster zone on India's 

map. For color full bulbs represents four disaster zones. Four switches to 

show areas & to operate single disaster zones. 

Structure :- Prepared on wooden ply board on which Indian map has 

been prepared. Led bulbs are fitted on India's map represents most 

affected disaster zones of India. 

Results :- Switches have two functions pressing first option a bulb starts 

glowing shows alarming center of that disasters, pressing second option 

bulb starts glowing shows whole areas of that disaster. 

Uses :- This project is very valuable and makes the people aware about 

disaster which occurs in specific areas so that they can prepare 

themselves to minimize effect of particular disaster.

AUTOMATIC RAILWAY 

CROSSING SYSTEM 

Introduction:- 

Railway is one of the cheapest mode of transportation in 

India, but in present time many railway accidents occurs 

due to human errors. So we try to develop a working 

model which is able to avoid the railway accidents at 

railway crossings. 

This idea works automatically, so that no gateman is 

required at railway crossings. 

Working Principle:- 

It works with completion of electric circuits connected to 

track with external by a train on the rail and taking help of 

light emitting diode. 

Material Used:- 

I.R. LED bulb, a DC motor, electric wire, battery, resisters 

and a toy train. 

Uses:- 

On man less railway crossing as well as all the crossings. 

Conclusion:- 

Such type of model is less costly as well as more 

effective.

Agricultural Development with Wormi 

Compost (By using domestic agriculture 

waste) 

My project is greatly inspired by the fact 'necessity is the 

mother of invention', which innovates me to solve the 

problem that directly relates to our life and gave harmful 

impact on it. In the process of observing, I determined to 

work on the domestic and agricultural waste that refused 

through our house. 

I observe that some people dispose it to their surrounding 

or in drainage whereas other literate people use dustbin 

from which it is taken by different agencies directly to 

dumping areas to dump in open environment. It is also 

observed that in it greater amount is of bio degradable 

waste and other material like polythene, plastic etc. 

It is remarkable thing that government is serious about the 

use of non standard size polythene. So, If these steps of 

government are taken in practice form polythene related 

problem can be solved mostly. 

Hence, by discussing my guide teacher I determined to 

work on biodegradable waste by converting it into wormy 

compost and use it in agricultural related development by 

which we can produce in better amount with standard 

quality fulfilled by nutrient and a in affordable cost. The 

quantity should also can be exported with confidence. We 

can get more value of our product due to its chemical free 

natural properties. 

This process will cheek the attack of chemical manure in 

our food chain, which decrease fertility of soil and 

harmful for both plants and animals andwe can lead a safe 

healthy life.

FLOOD AWARENESS BELL 

Flood is a natural disaster. It is caused by 

overflowing of water beyond its normal confines over 

dried land by destruction of dam. It causes great disaster, 

numerous death, diseases and ruins the resources of 

affected place. 

First we have to connect a UPS with an 

aluminum kit placed at the level of water considered as 

danger level. Now this kit is connected to a charger which 

will get 3 Volt DC after the circuit completes. This volt 

will be transferred to the alarm placed at a long tower in 

the center of the village. When water rises and reaches to 

the danger level, the alarm starts ringing. This water will 

alarm the people and they will manage their living in the 

meantime. 

From this we can draw a conclusion that, 

this is the best method to aware people of the coming of 

flood. Nothing in the world is much important than saving 

one's life. So, this project will save life, resource as well as 

entrance the glory of the country to give rise to such an 

important project. 

The only demerit of this project is that it 

needs a continuous supply of electrical energy so it needs 

an electric generator as well. And also its connection 

should be checked regularly to avoid any accident. So, 

alternatively it can be connected with a solar panel.

SOLAR COOKER 

Theory/Introduction:- Tthis is a stove but it is a Ajooba 

Stove because it is a device that cooks food without using 

conventional fuels like coal, gas, wood, Kerosene or 

electricity. 

The incident solar energy is reflected in to interior of the 

box containing the blackened conas create Green House 

Effect. 

Objective/Advantage of a Solar Cooker:- It does not exit 

any smoke or smell and does not pollute the 

environment. 

There is no possibility of accidents so it is safe to handle 

&save money as well as save all fuels. 

Used items/Materials Required:- Metal or rain forced 

plastic sheets or cardboard or wooden sheets, Aluminum 

foil. Thermo coal, insulating material, dimensions, and 

black paint tools for cutting rounding and other processes, 

fevicol or glue. 

Construction of Solar cooker:- Black painted surface are 

used as we know that they may absorb the maximum 

amount of heat from the sunlight or sunshine. Suitable 

aluminum allay or stainless steel. The pots are painted 

dull black on the outer surface so that they also absorb 

radiation directly. 

Working System of Solar Cooker:- Box type solar cooker is 

kept in infra red rays in sun shine or sun light, and then 

the temperature inside the cooker goes up to 1000 C to 

1400C in about 10 minutes. 

This heat cooks the food items generally like rice & pulses. 

Keep the beaker contains water and also the solar cooker 

in the sun of 10 minutes and measures their fuel 

temperature.

AN ECO FRIENDLY 

THERMAL POWER 

PLANT 

The Project is prepared in the active participation of the 

guide teacher Mr. Jagannath Prasad Thakur (PGT-Physics) 

of my school. The main aim of the project is to solve the 

problem of energy crisis without affecting the 

environment. 

Production of electricity using alcohol formed by the 

industrial waste of sugar industries. In the process biochemo-physical 

phenomenon is involved. 

During the decomposition of chopes and malases breaking 

of waste cellulose into methane and co2 by decomposing 

microbes takes place. In the fermentation process by the 

action of yeast sugar is converted to C2H5OH+Co2 , 

which is separated by healing at low temperature in above 

process biological & chemical phenomena are clearly 

visible. 

During the process of cooling, conversion of water vapour 

to water, movement of turbine & conversion of mechanical 

to electrical energy are physical phenomena. 

This whole process is less polluting due to the idealness of 

alcohol as a fuel and Bio-Gas as a fuel. The whole process 

involves renewable sources of energy.

HYDROPONICS WITH 

MUSHROOM CULTURE 

Hydroponics was used in the ancient period. Hanging 

garden of Babylonia and City palace of Udaipur is 

example of Hydroponics. 

In our model Hydroponics is used with 

mushroom culture for better and profitable cultivation. 

Hydroponics is actually soilless cultivation. In the 

Conventional Cultivation Water, Oxygen, Soil medium 

and nutritional elements are used. 

In hydroponics as a medium other material is 

used in place of soil. In this model following material are 

used : glass house, opaque ply wood, three rectangular 

poly propelyne tray, thermacol, coconut fiber and its 

waste, cotton thread, seed of mushroom, husk of wheat, 

insecticides etc. 

Innovation in the model: moisture and low 

temperature of hydroponics is used in mushroom culture. 

It is known that 180 c to 220 c is ideal temperature for 

mushroom culture.

MUSHROOM PROJECT 

INTRODUCTION: Mushroom is a fungus which can be 

used in eating. It's farming is beneficial. It's production 

value is affordable. It has its herbal, ecological and 

financial benefits. 

WORK PROCESS: The seed of the Mushroom is mixed 

with the boiled straw or husk and kept in a shady place 

and after that it is duly packed in polythene bags. After 

that it is kept in a hut or in a shady place. After 20-22 days 

Mushroom starts sprouting. 

PROBLEM AND SOLUTION: The biggest problem with 

the production of Mushroom was that its farming could 

have been made possible only in winter seasons. But I 

took it as a challenge and keeping in view with the 

farmers interest. I started my research to do its farming 

even in summer season. 

I am doing so I adopted following steps:- 

(I) Installad cooler in the production hall. But farmer 

can use zero energy cooling chamber or mud-built 

house also to curtail cost of production. 

(II) Mushroom bags were kept in cool and shady places. 

(III) Mushroom bags were carefully protected from 

sunlight. 

(IV) In order to maintain the place wet and moist proper 

amount of water was sprayed after an interval. 

(V) Seed was stored in freeze. 

(VI) Conservation of Mushroom was given due care. 

By adopting aforesaid measures I absorbed that 

production of Mushroom may be made possible even in 

summer season. 

CONCLUSION: Farming of Mushroom is possible round 

the year in Bihar.

ACID RAIN PREVENTION 

Environmental pollution is posing before us in various 

hazardous forms.Acid Rain is one of the most hazardous 

and devastating pollution of the present context,whose 

prevention is also a very tough task. This great concern to 

prevent it,inspired me to draw a new model to prevent the 

harmful effects of it.After,going through different terms 

and aspects related to acid rain,I have just prepared a 

model which will surely end up the menaces of acid rain 

Every SO ,NO etc. releasing factories must direct their 

2 2 

chimneys into the chamber. SO is an acid gas, and, 

2 

therefore, the typical slurries or other materials to 

remove the SO from the gases are alkaline. Lime and 

2 

lime stone are used as the absorbent in the presence of 

sea water (water containing salts). There acidic gases 

will react and the gas thus released will not cause the 

acid rain. 

This reaction would effectively cure the acid rain. The 

model can be very effective in deducing the menaces of 

acid rain at very effective and low cost.If this model will 

be adopted wide spread , the problems will be overcame 

or reduced to a great extent.

ETHANO BOTANICAL 

MEDICINAL PLANT 

The term Ethanobotany describes about the use of various 

plants. This is of economic, religious and medicinal 

purposes since ancient times. 

Our ancestor practices to use many common plants to 

cure the diseases and prevention from disease. Ayurvedic 

medicine derived from plant kingdom. And we are very 

well known that our ancestor were live longer life. 

In recent time in India pharmaceutical companies 

produce various types of medicines chiefly available with 

minimum expense. But these medicines have the bad 

effect also. The aim of my project is to relate the concept 

of remain healthy with the uses of plants available to us 

without any cost or harm. Natural medicinal plants help 

us to remain healthy and prevent us to get diseased. I 

want to make the young society to realize that we can 

remain healthy without the expense of penny.

A periscope is an apparatus based on the reflection of 

light. It is a tetra-faceted tube. Its upper and lower ends 

0 

are bent at an angle 90 .In it, a plane mirror adjusted at 

450, i.e.-it is Z-shaped. The most significant characteristic 

of this instrument is that an observer can view the distant 

objects distinctly. The observer hidden trenches can see 

the external objects clearly. 

It was used for the first time during the first world war 

(1194-1918).It was fitted into (used in) submarines. A 

sub- marine can see the ships sailing on the surface of the 

sea and target them. 

We know that Indo -Pak war was fought in 1971.The Pro- 

Pak U.S.A.(America) had sent its seventh fleet to the 

Pacific Ocean. Our friend Russia (The U.S.S.R.) retorted 

by sending its sub-marine built with new technology. 

America was forced to retreat its fleet.

ROLE OF FOOD CHAIN 

AND FOOD WEB 

IN BALANCING BIODIVERSITY 

The term biodiversity is used to describe the combined 

diversity at all the levels of biological organization. This 

model shows the interdependence of biotic components in 

the environment. This maintains the ecological balance. 

This model shows food chain and food web. Producers 

are green plants on which frogs are dependent. Snakes eat 

the frogs. If the population of frog is removed, then the no. 

of producers will increase and the no of secondary 

consumers will decreased. This will create ecological 

imbalance. Eagle and vulture are top consumers and 

complete the food chain. 

Every tropic level is important and there is a flow of 

energy in each tropic level. All food chain make an 

ecosystem. 

Bio-Diversity Conservation 

In situ conservation – endangered species are conserved in 

natural habitat. 

Ex situ conservation – includes zoological parks and 

botanical gardens. 

In India there are 14 biosphere reserves,90 national parks 

and 448 wild life sanctuaries. 

The Historic convention on biological diversity, earth 

summit held in Rio De Janerio in 1992. 

In 2002 the world summit on sustainable development 

held in Johansburg, South Africa. 

I want to give the message from this model that we should 

save each tropic level to maintain the balance in 

environment so that biodiversity is conserved.

ZERO ENERGY 

COOL CHAMBER 

Introduction:- Most of the horticulture crops including 

fruits and vegetables are perishable. The cool chamber can 

retains the freshness of fruits and vegetables for short 

period. This chamber can reduce the temperature up to 

0 0 

10 -15 C from the outside temperature and maintain 

about 90% relative humidity. 

Aim of the Project:- This method is economic and energy 

saver. The present trend world over is to develop a simple 

low cost cooling system for storage of fruits and 

vegetables. Every middle man can store the fruits and 

vegetables because it is cheap. 

Theory:- Preparation of low cost coal chamber by uses of 

bad conductor like as sand, brick. 

Materials:- Bricks, sand, bamboo, sirki, straw, Plastic 

pipes, source of water. 

Methodology and Construction:- 

1. Make a floor with bricks. 

2. Erect the double wall leaving a cavity of all four sides. 

3. Fill the cavity between the double walls with the wet 

sand. 

4. Make the frame of top cover with bamboo, sirki etc. 

Result:- Due to middle class men the price of 

horticultural raw material is 60-100% higher in mandis 

than in growing areas. Zero energy cool chambers retain 

the freshness of freshness of fruits and vegetables. 

Uses:- 1. Useful for temporary storage of dairy products, 

vegetables, fruits etc. 

2. This method can be used for mushroom cultivation and 

sericulture etc.

ENVIRONMENTAL POLLUTION: 

ARE WE GUILTY? 

Environmental Pollution is the biggest menace to our 

health. If the rate of existing environmental pollution will 

continue, the existence of human beings will be 

hampered. The main cause of environmental pollution is 

over-population. The need of food ,clothes, and shelter is 

increasing. To meet these demands, industries are being 

set up that cause pollution. The industrial effluents are 

drained in the nearby water sources without treating them 

properly that pose a great threat to the aquatic life. 

Another big cause of environmental pollution is 

"Deforestation". Deforestation causes soil erosion, global 

warming, disturbance in the rain cycle, desertification, 

migration of animals in search of new habitat. 

The main motto of my project is to spread awareness and 

to make the people aware of the hazardous effects of 

environmental pollution. It can only be reduced if we 

follow some united steps that are: 

– Reduce deforestation and try to plant at least one tree 

in a year. 

– Follow the three R's that are: Reduce, Reuse and 

Recycle. 

– Avoid use of plastic bags completely. 

– Control population by spreading awareness. 

– Avoid use of plastic bags completely. 

– Control population by spreading awareness. 

– Cleanliness of the society must be maintained. 

– Avoid smoking at public places.

SOLAR AC 

Introduction:- These days we are using electrical AC. It 

has its own limit. i.e. it needs electricity, it is costly etc. 

and harms us. Therefore we can use solar AC instead of it. 

Aim of the Project:- This exhibit can help us to save 

electricity; reduce global warming by saving electricity 

and work continuously in the presence of sunlight. It is 

cheap also. 

Theory:- Black body absorbs more heat than others. Hot 

air goes up according to law of convention and cold air 

fills the gap. Air with relative humidity 60%-65%, 

temperature between 230 C to 300 C and speed approax 

0.045km/hr is comfortable for humans. 

Materials: Wood, iron pipe, water pipe, brickstone, black 

paint, white paint and water container. 

Structure & Function:- A small house is made of wood, a 

black painted chimney is fixed with roof. A water pipe 

joins floor of house to an underground container. The 

container has brick stone and water. 

During day, temperature of chimney increases because of 

black paint. Temperature of air inside the pipe increases 

and comes out. It creates suction and again cold air comes 

from container to fill the suction in the room. 

Result:- Cold air with very low speed and humidity 

comes from container into the room. It makes the room 

comfortable for us. 

Uses;- It can be used in hot areas. It may be very useful in 

desert. It works continuously whole day in the presence of 

sunlight.

ENERGY FOR 

NEW TECHNOLOGIES 

Storage of Carbon dioxide in eco-friendly manner:- For 

storage of CO2 gas, we connect the chimneys of industries 

or power plants to a pipe and this pipe is then connected 

to a condenser. The pipe is dipped into the earth to the 

depth of about 3,800 ft(1km).Due to this depth, high 

temperature and pressure acts on the CO2 gas and 

ultimately it is converted into "solid-carbonates" 

permanently. The CO2 gas cannot come out from the earth 

due to the "cap-rocks". 

Formation of bio-gas in modified way:- Since, bio-gas is 

produced during anaerobic-decomposition of organic 

matters, like human and animal wastes. So, If we 

interconnect all the local toilets and cattle houses wastes 

to the digester-tank of bio gas system. Then, bio gas is 

produced in a comfortable manner. 

Irrigation of Jatropha-Plant:- If we do the irrigation of 

jatropha plant for one year , then it give us bio-diesel for 

about 35 years. A hectare of Jatropha has been claimed to 

produce 1892 litres of fuel. Also, by the selling of coproducts 

of biodiesel (from Jatropha), we recover our 

initial capital cost. 

Electricity production through Solar-Pond:- Solar Pond is 

one of the most promising technologies in solar energy 

utilization for varied purposes. It is the large area brine 

ponds about one meter deep in which vertical gradients of 

salt concentrations are maintained so that the most 

concentrated and most dense solutions are at the bottom 

of the pond. It is a low cost per unit area technology. 

e.g. Bhuj and Kutch districts of Gujrat, where about 

1,25,000kwh of electricity is produced per annum and 

about 80,000 liters of potable water per day.

RESOURCES OF ENERGY & 

CONSERVATION 

(Zero Energy City) 

In this model, I have tried to develop such acitviy that is fully 

depended on renewable & eco-friendly resources of energy 

&to check the wastage of energy. 

– Important devices developed in this model :- 

1. O.T.P House (Optical Thermal Power House) -: It converts 

solar energy into electrical energy .It produces 40%more 

electricity than a solar plate because it uses both components 

light and heat of energy. 

2. Refrigerator without electricity-: This refrigerator works on 

the concept of evaporation .The heat of the inner part of this 

appliance is used as required energy in evaporation and then 

temperature comes down to13o to 14o C. 

3. Air conditioner without electricity: It works on the concept 

of transformation of heat. 

4. Energy Producer door & swing: With the help of this 

appliance we convert unnusefull kinetic energy into 

electrical energy. 

5. Self operating water tank &motor: Through this device we 

can check the wastage of energy & water, when the tank is 

full of water then it turns off automatically. 

6. Energy Producer speed breaker: When a transport crosses 

the speed breaker then it rotates and electricity is produced 

because this breaker is connected with a generator. 

7. Self operating street lights-: This light automatically turns 

off in the day and turns on in the night. 

8. Production of energy from waste material 

9. Solar Chimney 

10. Solar Water Purifier

PRODUCTION & 


ENERGY 

Introduction: - Production and conservation of energy in 

sustainable village and city by the model. 

My team belongs to a rural area in which there is acute 

problem of electricity. So we try to solve this problem with 

the help of available resources. Just like Solar system, Bio- 

Gas Plant, Recycler, Purifying System, Hydro energy, Geo 

thermal energy. 

And Our other model is that in which we discuss the 

power bulb in which use its advantage in our daily life. 

Purpose :- To produce and conserve the electricity in our 

related area with the help of sufficient resources that is 

explain at above in our introduction, Prevent the pollution 

Use of Bio- Mass manure in the Place of NTP and other 

Chemical fertilizer. 

Principle :- Theme of this project, conservation of 

electricity. 

Difference between power dissipitated in CFL and a 

normal bulb and its advantage in our daily life. 

Material :- CFL, Normal bulb, Switch, Connecting wire, 

card board, Thermocol, Battery an Some toys. 

Working :- Electricity is also a form of energy which is 

used in city frequently . 

In Compression of bulb CFL use less amount of electricity. 

So by using CFL we can save electrical energy. 

Result:- It is more effective in which we have to save 

money in our daily life. 

Use:- It is used to save electricity and energy. 

Fault :- CFL produce CFC Gas, Which pollute our 

environment, debris of CFL bulb Cause Pollution.

MAGNETIC LOCK 

INTRODUCTION:- In the world, we see many types of 

locks which is operated with the help of key. But in this 

lock, We use the electric Switch to open the lock. 

AIM OF THE PROJECT:- In my project, I want to make 

such lock which can't be seen from outside and is 

operated by switch. The thought of making this project 

came in my mind when it is seen that electro magnet 

attract iron-rad. This very phenomenon introduced my 

self to work on above project. 

THEORY:- My project is based on electro-magnetic theory. 

It was given by james clerk Maxwell in 1873 A.D. When a 

solenoid is coiled and electricity passed over it, results a 

magnet. 

DEVICES:- Plywood, Switch board, Switches, Solenoid, 

Coiling Wire, Simle wire, Plug, Insulator etc. 

METHODOLOGY:- Any Person can't open the lock since 

he/she hasn't any knowledge about the secret switch. 

USE:- This lock is highly safe and can be used for safety 

purpose at any place.

WIND POWER PROJECT 

A wind power turbine is an oil free automatically operated 

device that converts kinetic energy from the wind also 

called "Wind Energy" into useful Mechanical energy; A 

process known as "Wind Power". 

If the "Mechanical Energy" is used to produce electricity 

the device may be called "Wind Turbine" or "Wind Power 

Plant". Here a generator converts its mechanical energy 

into electrical energy. 

If the "Mechanical Energy" is used to derive machinery, 

such as for device is called a "Wind Mill" or "Wind Pump". 

Similarly, it may be called "Wind Charger" which is used 

to charge batteries. 

The smallest turbines are used for applications such as 

battery charging or auxiliary power on boats, which large 

"Grid -connected arrays of Turbines are becoming an 

increasingly important source of wind power produced 

commercial electricity. Here simply stated a wind turbine 

works. The opposite of an electric fan. Instead of using 

electricity to make wind like a fan, "Wind-Turbines" use 

wind to make electricity. The wind Turns the blades 

which spin a shaft which connect to a generator and 

makes electricity. Wind power ,as an alternative to fossil 

fuels is plentiful renewable widely distributed clean 

produces no green house gas emissions during operation 

and uses little land any effects noise on the environment 

are generally less problematic then from other power 

sources. The monetary cost per unit of useful energy 

produced by such device is similar to the cost for new coal 

and natural gas installations although wind power is a 

popular form of energy generation the construction of 

wind farms is not universally welcomed due to aesthetics.

New Process of refining Sugar from 

residuary product (Khalli) of 

Mustard Called "Brassica Sure". 

Process:- After crushing mustard the residuary 

product(Khalli) is washed with water and dried. Then 

Hydrogen peroxide is mixed with it and again dried in the 

sun. This dried "Khalli" is made into powder by crushing 

it in crusher machine or in pestle and mortar. This powder 

is burnt in a furnace at 7000 C. After burning, the 

residuary product is used in sugar refining. This new 

process of sugar refining is called 'Brassica Sure'. By this 

process we get more shinning and more purified sugar. 

Significance:- The benefit of this process is no chemical or 

charcoal made from animal bones is used in this process. 

here are several advantages of this process of sugar 

refining: 

a. Low Cost. 

b. Farmers growing mustard product get inspiration and 

proper value of their product. 

c. Will have not to face opposition against use of animal 

charcoal in sugar refining. 

d. There will be less environment loss. 

e. The use of several chemicals which are prohibited 

under Food Safety Act will be stopped in sugar refining 

process.

MAKING OF LIFE JACKET FROM 

EMPTY PLASTIC BOTTLES 

The earth is the only planet of the solar system on which 

life exist. In comparison with other creatures man has 

developed his senses. Due to development man has 

created danger for his own home, the earth. science has 

changed our life style and standard of living. It has given 

us many facility and technologies for years centuries. 

Thus, science is boon for men and their society. Today we 

are doing injustice to the earth to fulfill our increasing 

physical needs. We are using natural resources blindly. 

Trees and woods being cut down, that is why the balance 

of nature and ecosystem has been disturbed. Many 

creatures and beings have been disappeared and many are 

to be vanished. Many wild animal lives such as lion, tigers 

etc are in danger. 

All creatures on the earth have suffered from 

pollution and imbalanced of environment. Man has been 

also suffering from it for the few years. The meltings of 

glacier, flood, earthquake, Tsunami etc is due to 

imbalanced global warming in nature in our country, the 

climate of Jammu & Kashmir, Rajasthan has changed and 

have to face other natural phenomena. 

Yet man has not become conscious. If the 

development goes man will destroy their own home, the 

earth and they self fall on the ditch of economic 

development. 

To save this auspicious planet, we the 

children have struck idea. That empty plastic bottles 

which are not destroyed using them home be can save 

environment and cutting of trees and forests.

WATER CONSERVATION 

& HARVESTING 

When the flood occurs, then the river of more water 

should be diverted to the river of less water to the barren 

land. So that agriculture should be done without any 

problem. 

Water which is used for drinking & bath beneficial and 

non-beneficial. water is used in many places like in house, 

farm land industries, water pollution is also an important 

reason by which water is affected. 

Uneven amount of rainfall leads to flood. Therefore water 

conservation is necessary. For the solution from natural 

disaster. I have made this project on water resources. From 

this project I want to tell that how we should utilize or 

conserve water by making tanks, Small embankments, 

stream etc. in hilly areas due to heavy rainfall. the land is 

dug so that water is filled in the dug hole. This is the 

reason why speed of water falling decreases and therefore 

level of water does not increases and when the dug land is 

filled with water, the soil come along with water due to 

which consumption of water decreases and chances of 

flood increases.

ABACUS 

Introduction : Modern age is the age of Science. Its assumption 

without Mathematics is in vain, but a large number of Students do 

not understand Mathematics well. Its root- cause that they do not 

understand the fundamental concept of mathematics, As a result, 

they Start hating Mathematics so, I have Prepared my Model 

Abacus '' from which some fundamental concepts of Arithmetic 

can be understood easily, it makes Mathematics easy. Also my 

model is useful in everyday life. 

Purpose :- 

nd 


Exhibition 

& Project 


(1.) To remove fear of Arithmetic 

(2.) To Produce interest to wards Mathematics and to improve 

Self- belief in students though " Learning by doing" 

(3.) To make teaching-process interesting and able to teach easily. 

(4.) To use Abacus as a teaching instrument 

(5.) To introduce children with the fundamental concept of 

Arithmetic in Just a play mood. 

(6.) To understand Addition, Subtraction, Multiplication and 

Division easily. 

(7.) Since, a larger part of Arithmetic is based on Addition, 

Subtraction, Multiplication and Division so it can be used in 

many Sub- Subjects such as statistics, Probability. Algebra etc. 

Principle :- My model " Abacus" works on the principle of 

"Counting" which is the fundamental concept of arithmetic. 

Required article:- 

(1.) A small wooden- frame 

(2.) String. 

(3.) 63 Small soil- built sphere. 

(4.) 20 Stamp pin. 

Construction:- 63 Small soil- built sphere is fitted in the wooden 

frame. All the Spheres are in 9 horizontal row. There are 7 spheres 

in each row. Each horizontal row is divided into two sides-(1.) 

Right side and (2.) Left side. Both the sides are divided by a string. 

In the Right side of each horizontal row there are two spheres in 

which each sphere contains the basic value of 5 in the left side of 

each horizontal row there are 5 spheres and each sphere contains 

the basic value of 1.

Biodiversity of the medicinal 

plants in the wasteland area of 

Banka district in Bihar and its uses 

Introduction:- Biodiversity is the variety of world 

organism including their diversity and the assemblage 

they form, 

Aim of the project:- Survey and documentation of the 

medicinal plants and study of Biodiversity of waste land 

of Banka. 

Theory:- Herbal medicine has not any side effect and very 

useful for treatment of diseases. 

Materials:- Paper, Pen, Pencil, Documentation Register, 

Herbarium Sheet etc. 

Methodology:- Wasteland of Banka was extensively 

surveyed at a regular interval in order to generate database 

of medicinal plants, their local and botanical name and 

uses. Identification of plants was done with the help of 

available literature and Herbarium Specimens preserved 

in university. Department of Botany, T.M. University, 

Bhagalpur. Local Vaidya, Hakim and Jangurus (Vaidya of 

Tribal People)of Banka district. 

Result:- Bihar has 08 categories of waste land. Banka has 

530.63 sq. k.m.(17.58% of total area) as waste land. During 

the field survey, a total of 68 medicinal plants were 

recovered during the survey. 

Uses:- Herbal medicines are based on biodiversity efficient 

for instant relief to treatment of chronic diseases having 

no any side effects. 

Demerits:- Documentation of more plants and making 

Biodiversity Register (BDR) of Panchayat level is needed. 

Procurement of more medicinal plants are also needed.

INNOVATIVE VEHICLE 

UNLOADING SYSTEM 

In the present model simple lifting and rotational motion 

theory and Hydraulic principle is used. 

The dala in which load is kept is joined with the motor, 

which is controlled by the driver with the help of the 

switch. The motor system in which gear is lifted is made 

to unload the dala from beneath. The three motor systems 

have been separately joined and switched with the help of 

these switches. The driver activated the motor system by 

hydraulic principles up and down to unload the goods 

kept in the dala. 

Working System:- For Unloading goods in a narrow 

streets, first of all the dala is moved to the desired 

direction with the help of the switch. Then from one side 

the motor system is held up with the switch and another 

side held up hydraulic principles, is moved down to 

unload the goods. Due to weight of the goods the door of 

the dala opens and all goods fall on the desired spot. 

Advantages:-

LIGHT PRODUCTION 

FROM THE WASTE 

2012 

Materials Used - DC Motor, Dynamo, Condenser, Switch, 

Diode. 

Scientific Theory - Light Production from the waste. 

All the waste from the village or city is collected and sent 

to the plant where the wastage is sent to furnace with the 

help of conveyor belt. By burning, a gas is produced and 

vapours are formed by heating the water. Vapours are sent 

to turbine through pressure pipe. When the dynamo runs, 

the magnetic field charges the generator and current is 

obtained. The current is sent to the transformer where it is 

transformed to light. This electricity is used in various 

ways in day-to-day life. 

Application - 1. Alternative use of electricity. 2. Removal 

of waste from village or city. 


129

WATER FUEL 

Materials Used - Empty Battery, Silver Rods Battery, Ply, 

Wires. 

Scientific Theory - When electricity is passed through 

ionized water i.e. water along with salt or acidic water, 

then water molecules split up in to hydrogen and oxygen. 

Today our greatest problem is constant increase in the 

price of Petrol & Diesel & even CNG. Today in our world 

there is about 3/4 of salt water. My project converts this 

salty water in to such a gas which could be easily used in 

place of CNG & LPG and can cook food, run vehicles & 

much more. Most important point is that it does not 

release CO in the air when burnt, as other fuels do. It 

2 

works with salty water, urine & waste water. Hence it is a 

very useful & magnificent project that could save our 

green Earth. 

Application - In this Project is established in our homes & 

solar panel is used for source of electric current then it 

could be used as cooking gas in placement of LPG. It could 

be used in cars & other vehicles as fuels and also as the 

source of electricity as dynamo.

MAGNETIC CRANE 

Materials Used - Wooden frame, Plywood, Sting, Copper, 

Pulley, Blade. 

Scientific Theory - According to electromagnetic 

principle, when current in passed though a non conductor 

frame having a rod winded by copper wire then it acts a 

magnet and as soon as we a stop the flow of current, its 

magnetic quality ceases. 

When we lift any heavy iron objects, cranes are and used. 

Here we bring a rod coiled with copper wire near the 

heavy iron object which is connected with handle. 

Moving the handle to bring down the copper coiled rod 

and start the battery and the current flows and it work as a 

magnet. Here the iron object attract it. The handle helps is 

move the rod where ever needed. Now again with the help 

of handle bring down the string and stop the supply of 

current and it ceases its magnetic quality and the object 

get released. 

Application - 1) To lift up heavy objects. 2) Heavy objects 

drowned in water or deep pits can be lifted. 3) In factories 

to lift up heavy objects where workers are few in number. 


ELECTRO MAGNETISM 

Materials Used - Wire, Battery, Bulb, Copper Wire, Board. 

Scientific Theory - When current is passed through a coil 

of copper wire, it creates a magnetic field and an iron rod 

induced in this coil becomes a magnet. This is an 

electromagnetic. 

This rod induced in a coil of wire through which current 

is passed becomes a magnet. This electromagnet is very 

powerful. 

Application - 1) This electromagnet can be used to lift 

heavy iron materials in factories. 2) To separate or 

magnetic materials.

WATER: NO DIRT NO GERM 

Materials Used - By uv-c Ray (Tube) modify system. 

Scientific Theory - The genetic information of germs & all 

other creatures is stored in either DNA or RNA. Short 

wavelength (250 nm) ultraviolet radiation, also known as 

uv-c radiation damages DNA & RNA & therefore destroys 

the genetic information of all creatures. 

This apparatus kills disease producing germs in the 

drinking water, with the help of waves of short wave 

length i.e. UV radiation. The apparatus can be run on 

electricity from three different sources. 220V Ac of 

domestic supply 12 V of battery or cycle dynamo. This 

versatility of power source makes it especially useful in 

rural area.

PIEZO ELECTRIC EFFECT 

Materials Used - Card board, Thermocol, Wooden stand, 

Lights, Battery. 

Scientific Theory - One side of Piezoe materials is 

connected to a rigid post at the base and another side to 

the seismic mass. According to the Newton's law force is 

equal to the product of acceleration and seismic mass. By 

the Piezoelectric effect a charge output is proportional to 

the applied force. The charge to generate is used to light 

street lights. 

Piezoelectric effect is the ability of certain material to 

generate electric charge in response to applied mechanical 

stress. When the Piezoelectric is placed under mechanical 

stress a shifting of positive and negative change occurs in 

the material which then results in an external electrical 

field. Here it is a device that would harvest the energy 

from the vehicles driving over the road. The electricity 

generated can be used to glow street light directly and 

during the day, the energy can be stored in a nearby 

battery on in any power storage system. 

Application - Piezoelectric material is used in the gas 

lighter to produce spark in them. The energy harvested 

from driving vehicles is storage in power storage. This 

energy can be transformed to houses. It can provide 

energy. The electricity from 1 km. of electric road can 

produce around 80 kilowatts which is enough to light 40 

houses. 


L.P.G. GAS SUBSTITUTE 

Materials Used - Kerosene, Petrol, Water, Air pump, 

Burner. 

Scientific Theory - In the present of O2, the gaseous state 

of kerosene, petrol can be used in place of LPG. 

Liquid Petroleum Gas is very necessary in our daily life. 

Due to limitation of its resource we are thinking of 

alternative for LPG. We take three bottles, one bottle of 

petrol, one bottle of water in middle and other bottle of 

kerosene oil. These bottles are connected with pressure 

pipes. With the help of pump, we pass pressure in form of 

vapors of petrol which move to water from here the vapors 

pass is kerosene oil which in filled with a pipe connected 

is a burner. Now these vapours though pipe reach the 

burner and it starts burning. Thus the alternative LPG is 

produced. We can use this method since petrol and 

kerosene oil are easily available. 

Application - In kitchen this method in a substitute for 

LPG.

Materials Used - Sensor, Motor, Transformer, Led-Light. 

Scientific Theory - Works on the principle of pressure. 

We used three sensor to identify any over loading goods. 

When the over loaded vehicle enters in first sensor the 

buzzer starts ringing. Now when it enters the second 

sensor the red light shines indicating over loading. And 

again when the vehicle reaches the third sensor, the 

barrier closes automatically and red light shines. In this 

way we can identify the vehicles which are over loaded 

more than 50 tons. 

Application - This system help us to identify very heavy 

loaded vehicles.

NTPC Electricity Generation 

Materials Used - Pressure cooker, Stove, Tin Sheet, Ply 

Board. 

Scientific Theory - This is based on law of energy 

conservation. 

Here we drops the coal in a track hopper where it is 

crushed in to pieces of 200 mm size. This crushed coal is 

passed to bunker where it is stored and drawn in mill. 

Now this crushed coal in transfered to a furnace with 

water in it. On heating the furnace the water present in it 

converts in to steam, which comes in contact with a 

turbine. The turbine starts rotating. When the turbine 

rotates the steam that comes in contact with the turbine 

changes to water which is passed to a condenser. From 

here it is sent to a cooling tower which again goes through 

LPH Deaieretor & HPH drum then to a furnace. Now dry 

steam produced in it comes in contact with turbine and it 

rotates very fast. This generate electricity. 

Application - Electricity produced is very necessary in our 

daily life. 


Materials Used - Wooden, Card board, Mud, Electrical 

equipments. 

Scientific Theory - 

Gram Madkoo is a village on the bank of river Shivnath. 

Every year during rainy season the village is disturbed by 

the flood water of this river. A great loss of life and 

property is faced by the villagers. So before the coming of 

flood for prior information flood indicating machine is 

built. With this the people come to know of the situation 

and get prepared for any safety measures.

EMERGENCY MOBILE 

CHARGER 

Materials Used - Lemon, Copper Coin, Nail, Battery. 

Scientific Theory - Based on electrolysis. 

In emergency mobile charger we use lemon battery in 

which two electrode of different metals like Copper Coin, 

Zinc or Nails. 

Here we take many lemons, since from one lemon 

sufficient current can not be obtained. 

Copper coin functions as +(ion), electrode as a Cathode, 

Where as nail functions as - (ion), electrode as Anode. By 

this electro chemical reaction take place in which 

potential in developed at both the ends. And by this we 

can charge the mobile. 

Application - In emergency cases we can use this method. 


Materials Used - Board, L.D.R., R.C., Tube light, L.D.R. 

Plate, Transistor. 

Scientific Theory - The main Principal is to switch on the 

light automatically when it is dark and switch off 

automatically when there is sunlight. 

The working of this model is based on the use of LDR 

(light dependent resistance). LDR is very sensitive to light 

which increases the resistance of RC box and the light gets 

switched off automatically. In the evening when it is dark 

the resistance becomes less and the lights gets on 

automatically.

COMPARATIVE STUDY OF ALCOHOL 

PRODUCTION FROM 

CANE JAGGERY AND PALM JAGGERY 

The aim of this project is to make an attempt to produce alcohol 

from a crude source of sugar using immobilized Baker's Yeast 

(Saccharomyces cerevisiae). Immobilization is carried out by 

entrapping yeast cells in an inert solid matrix such as Sodium 

Alginate which enhances viability as well as prevents damage to the 

cells. An advantage of immobilized yeast is you can always separate 

the cells and transfer into other fermentation vessel without much 

difficulty. 

The sugar source selected for the present work is jaggery because of 

its ready availability and as it contains few reducing sugars which 

can be easily fermented, and non-reducing sugar mainly sucrose 

which on breakdown yields reducing sugars. Here we use two 

different types of jaggery (cane jaggery and palm jaggery) differing in 

their source of origin and hence their sugar content. Under 

anaerobic conditions, Yeast ferment hexose sugars to ethyl alcohol 

and carbon dioxide. 

The overall fermentation process can be summarized by the 

equation: 

C H O yeast 2 C H OH + 2 CO 

6 12 6 2 5 2 

Glucose Ethanol Carbon dioxide 

The fermentation process for obtaining best results requires 

anaerobic conditions, which due to lack of facility could not be 

strictly maintained. The process takes around 4-5 days. Studies on; 

optimization of temperature was carried out by incubating the 

fermentation medium at three different temperatures and 

optimization of pH was carried out by adjusting the pH of 

fermentation medium at three different values. After which the 

fermented medium was distilled using a simple distillation unit to 

purify the alcohol and volatile acids. The distillate is used for 

estimating the concentration of alcohol using Potassium dichromate. 

Estimation of Total Acidity (volatile and non volatile) was carried out 

using titration method. The comparative results (of cane jaggery v/s 

palm jaggery) are shown by graphical representation.

EMBEDDED SYSTEM 

FOR POWER SAVINGS 

SYNOPSIS 

The project aims to solve the project of high energy 

consumption which leads to environmental pollution and 

also shortage of electricity in some places. The project 

aims to cut down this consumption at a domestic level. It 

uses a system that automatically turns of the lights and 

fans along with the selected appliances in a room. It 

employs a system using a PIR sensor, i.e. a passive infrared 

sensor that enables it to differentiate the body heat of 

a human from the surrounding area. The system is low 

cost at only Rs. 150 a unit, and is completely autonomous. 

It is fully customizable and be adjusted according to the 

needs of the user. This system allows flexibility by 

allowing a central control unit to be attached. Additional 

features can be added to the central control unit such as 

displays and a keypad to log energy usage and to work as a 

burglar alarm system. This type of system has less false 

triggering factors than existing systems. It is designed 

with a plug and play function in mind.

HYDROPONICS 

Is it possible for a family to grow its own fish just as it is to 

grow Vegatable. in the garden? "Yes". Fish is one of the 

healtiest, most nutritious source of protein available low in 

calories with high levels of omega fatty acids. but the cost 

of sea food is increasing and its quality & safety is a big 

questions? Similarly the demand for organic farmed crops is 

increasing tremendously, due to the health probelms faced 

by people. In order to solve these problems here comes a 

technique combining Aquaculture and hydroponics, Which 

produces excellent result and the advantages are just mind 

blowing. The beauty about it is, that it can done even by a 

middle class person as the expenditure is not very high. 

When fish is cultured intensively in 'closed' re-circulating 

aquaculture system there is an accumulation of nutrients 

within the cultured water as a result of the intensive 

feeding of the fish. The biofiltration of nitrogenous wastes 

result in the build-up of nitrates and the solid wastes of the 

fish provides additional organic nutrients. The recovery of 

these nutrients can be accomplished through the integrated 

of aquatic or terrestrial vegatables. Instead of using nutrient 

solutions comprised of inorganic sources of nitrogen, water. 

When combined with integrated pest management 

techniques the resulting hydroponic crop will be 

considered organic and free of herbicide and pesticide 

residues. In Goa our weather condition are conducive for 

both fish and plant culture throughout the year. The fish 

cultured will be Tilapia mosambica which are heavy eaters 

and they are also a delicacy in Goa. Tilapia is also 

considered as a species to control malaria.

EXRACTION OF KOKUM 

The western Ghat is full of flora-fauna. The Goan people 

have special food fish curry and rice. The kokum tree has 

a significant medicinal importance along with food. The 

seeds of this tree are used to extract vegetable edible 

butter oil. 

The village people use primitive method for extraction. 

The primitive method is a lengthy boredom and time 

consuming hence people do not use extracting kokum oil 

nowadays. People do not know the importance of this 

butter oil, so there is a fear of vanishing the natural 

product. 

It is in order to keep product alive for generation to come 

and make proper use of the natural product, it is decided 

to study the extraction of kokum seed oil and to facilitate 

the natural kokum product and make use of fit in daily 

life. 

The seeds of kokum along with food pulp is collected and 

dried in a specially designed Solar drier. The dried seeds 

are crushed in a stone crusher, locally called 'Ragdo'. The 

crushed powder boiled with water using a Solar Cooker. 

the boiled extract is cooled in a specially designed earthen 

pot cooler. The skimmed floating part is used as 

Mangosteen Oil (kokum butter oil). 

Uses of Kokum Butter 

It is mainly use as edible oil. It used in skin product. It is 

used in soaps, Bams and cosmetics. It is considered as 

natritive. It is a remedy for diarrhea and dysentery. 

Various part of the tree like root, bark and fruit are used 

for treating piles, abdominal disorder.

RADIUS METER 

Radius meter is a mathematical instrument. It is used to 

measure the radius of cylindrical objects specially big 

cylindrical objects by just touching the surface of that 

object. It can measure the radius from both external as 

well as internal i.e., by touching the external curvature or 

internal curvature of the object. It can also be used for 

spherical objects and distant cylindrical objects (in some 

cases) and it works in six different ways. 

The theorem, ”there is one and only one circle passing 

through three given non-collinear points” which gives the 

relation between the arc and the radius is the working 

principle of this instrument. A triangle is drawn such that 

it base forms the tangent to the circle and the vertex 

opposite to the tangent touches any one of the other two 

points to get the relation with the radius in terms of 

triangle properties. 

By passing a line such that it bisects the hypotenuse and 

intersects exactly at the centre of the circle according to 

the theorem. Now this line forms hypotenuse of another 

triangle and one side of this triangle forms the radius of 

the circle; base (tangent) is common to both the triangles 

as mentioned above. By applying similar triangles 

properties to these two triangles formula is derived for 

radius interms of other two sides of first triangle

HAIR BOOM 

2012 

Rationale behind construction of the models : We all 

know our presence is very fast and we are facing various 

pollution like, air pollution, water pollution and disturb 

our environment. We are here form different kind of 

pollution. Like air, water and soil pollution. This is our try 

how to clean water pollution and it's name is " HAIR 

BOOM ". 

Scientific Principle:- If we observe microscopic image of 

hair, we see index design. So that index design and 

capillary action the point of oil pulled to hair. 

Objectives:- To Decrease the oil water pollution in sea by 

using hair boom. 

To protect water lives and botany of sea. 

Description:- In the model we have used a plastic net, 

Human Hair, Net and small boat. we put human hair in 

plastic net and fixed it by using rubber ring. Our hair 

boom is ready to use. Then we hanging hair boom in to 

boat. The location of hair boom is on the surface of the 

water. 

We can see the oil in the sea is absorbed by the hair boom. 

This is due to principal of capillary action, the point of oil 

pulled to hair. After some time when the hair boom is full 

fill of oil. Then we pulled up hair boom and remove the 

oil by using pressure machine. The removed oil is put in 

another dish. Now the empty hair boom is ready to use 

again.

WASTE PLASTIC AND 

GIVES FUEL 

Introduction: In our school the children eat food, packed in 

polythene plastic bags and then throw in the playground or 

anywhere. When the collected garbage plastic is burnt during 

cleaning time, we faced the harmful smoke afflicted to the eyes 

much and also inhalation problem. 

Plastics like polythene less than 20 microns affects the 

environment as well as the problem for drainage that everybody 

knows. Henceforth we have decided to carry out this project for 

recycling the polythene plastic by making solutions in the form 

of hydrocarbons. 

The Scientific Principle: To convert Hydrocarbons obtained from 

waste plastic to the gas and then in liquid by heating them in the 

absence of oxygen. 

Objectives: To control the environmental pollution of plastic by 

recycling it as it is hard to dispose it naturally. 

Description: All of first take a metal-tin. Fit a metal-pipe passes 

from its cap. Fill the tin with waste plastic. Pour two or three 

pieces of charcoals as Stimulants. Close the tin air-tight by 

metal- pipe passed cap. Put a glass jar at the end of metal pipe. 

Close it with holed rubber-cap. 

Now plastic will start to melt by heating it at 140˚C to 240˚C 

temperature on the heating apparatus. It will convert in gas. This 

gas will be liquefied by cooling when it will pass through steel 

pipe. It will be collected in glass jar. Some smoke will also be 

present with this liquid. To destroy this smoke, join another glass 

jar with this liquid jar with pure diesel in it. The smoke will be 

absorbed in pure diesel and it will stop pollution. 

Now take this liquid collected in jar in another conical flask. It 

will be converted in gas by heating it at 350˚C to 450˚C 

temperature. By passing this gas through cooling pipe, it will 

convert in liquid which is known as Thermo-fuel Diesel 

Remaining liquid in flask will convert in grease by cooling.

PURIFICATION OF POLLUTED 

INDUSTRIAL GASES 

Introduction:- Today's World is facing the great problem 

of pollution and this is our humble attempt to reduce 

pollution to some extent and create awareness of the 

deadly effects of the pollution. To fulfill these objectives 

this project is prepared. 

By implementing this project, We will be able to reduce 

the air related pollution to some extent. Moreover this 

project gives us its byproducts which can be creatively 

used. 

Scientific principle Involved :- Reducing the proportion 

of pollution from the environment . 

Objectives: - To create awareness of dangerous effects of 

the pollution. 

Materials required for the construction :- Boxes of tin, 

Boxes of plastics-5, PVC Pipe 10 ft., Bends and Exhaust 

Fan, K2Cr2O7, KOH, Oil, Water and Inductive Coil 

Description :- Firstly fixed exhaust fan in tin box then 

produced polluted air is sent through PVC Pipe alternately 

to oil chamber, KOH chamber, Water chamber, K2Cr2O7 

chamber, Inductive coil chamber. From the ind. Coil 

chamber purified air is released in environment. 

Application:- Pollution creating air such as CO2, SO2, 

NO2 etc.. is absorbed in various chambers ultimately 

producing pollution free air. 


BIO-DEGRADABLE 

PLASTIC PRODUCTION 

Introduction:- In the present scenario the whole world is facing 

the biggest problem of pollution created by plastics garbage in 

our environment. The only solution of this problem is to stop the 

using of plastic bags or should search another option. The real 

problem of environment is not plastic but the structure of 

plastic, which is not decomposed (non bio-degradable) in soil for 

many years and after during its produce toxic gases which is 

very dangerous for the environment. Looking to this idea our 

project is more useful to solve this problem. Protecting 

environment by making Bio-degradable plastic by using the 

nature polymer from plants such as maize, potato and sugar etc. 

Scientific Principle:- Starch is one type of natural polymer. 

Objectives:- To create eco-friendly, renewable and 

environmentally safe plastic from agriculture product. 

Description:- In the model we have used a burner, stand, bowl 

and starch of maize or starch of potato or wheat, vinegar, 

glycerin. At very first 22 ml of water is added in 4gm of starch 

and 0.5ml of vinegar, 2.0 ml of glycerin are also added. They are 

mixed well in the bowl. The bowl is kept on stove temperature. 

A sticky material is formed and it is left for 48 hours on smooth 

surface. 

Here starch is working as polymer and glycerin is working 

as bounding agents. 

Our main purpose of the model is to create ecofriendly, biodegradable 

and environmentally safe plastic from agriculture 

production and we can control co2 in air. Natural polymer takes 

only 30 to 180 days for decomposed and hence safe for 

environment. Bio-degradable begs are better and safe for 

hygienic packing. By this process we can resolve the problem of 

global pollution and same human being and living things on the 

planet earth.

renewable energies like solar & wind energy, we have shown a 

simple working model. This will take care additionally the line 

loss of electrical energy when very big power center supply 

energy to remote a dist. area , The model is very useful for hilly 

areas , remote areas where installation of line is difficult more 

difficult to maintain the services . 

Scientific Principle: Solar & wind energy converted into electro 

- chemical & electrical energy in turn. 

Objectives: To produce cheap and pollution free energy. 

Description:

Materials Vertical axis turbine, generator, chargeable battery, 

inverter, solar panel, model of house, wooden block, bearing. 

Construction and Working As can be seen from the model a 

wooden base is used to fix the vertical axis wind turbine, the 

generators are attached connected to dynamo, so that wind 

energy (wind at the speed of 2 km/hr. )is sufficient to produce 

the 400 w electrical energy . This is noiseless electricity 

produce. 

Actual: In order to have 400 W rated power we need the 

wheels of diameter (1.2 m / 1.06m ) made up of aluminum 

alloy blade 3 minimum speed of wind 2.5 m/s to 15 m/s , can 

tolerate 65m/s the a.c. generator with 3 phase wind turbine will 

charge battery of 12V/20 amp . in turn with the help of 

inverter 230v/220 amp current is obtained .depending upon the 

capacity of battery it will sufficient to lighten the assembly of 

8/12 house colony for 8 Hrs. or street light for 12 Hrs. of street 

this type of installation in various countries are carried out for 

captive consumption of house hold societies. Additional power 

is bring supplied to electric distribution companies to generate 

revenue. solar panels are connected in parallel so that other 

than very heavy rainy days it will support the system when 

wind is less than 2.5 m/s is boost the working capacity of 

system .

GENERATION OF ENERGY 

Introduction :- In today's progressive era, it is must to awake 

the countries of the world in order to decrease the energy 

crisis. This has been forming a new form of today's research 

to stop global warming and future energy crisis. For the 

energy crisis the shortage of Fossil fuel like petroleum 

product are responsible for energy crisis as well as for the 

Global Warming is also product of this. These both problems 

can't be solved without finding other options. There are no 

doubt that lots of non conventional are available or find out 

energy option only 2.5 % of these energy is in production of 

2 crore G.W./hour electricity. With the contribution of non 

conventional energy source like solar, wind etc. reaches to 

30% of total our requirement. To fulfill this energy gap as we 

have put forward the little strange but effective option.

OBJECTIVES:- To awake people from their sleep of 

ignorance about natural calamities by providing primary 

information or precaution and to develop proper structure, 

strategy, technology. 

DESCRIPTION:- In the model we try to introduce the 

modern national or express highway. We have divided the 

highway in certain blocks. In each block we put some 

sensors which are directly connected with control-room. 

In control-room there is light and alarm system connected 

with each and every block. If in any block accident will 

occur the respective block will become alert in the 

control-room and light on and alarm continuously goes on 

ringing. Immediately the control-officer takes a proper 

step and sends the rescue-team in that particular block. 

With the help of this model, we come to know about the 

exact place and location of the accident without any 

information from the injured person or any person. In the 

model we also try to introduce many working models like 

earthquake alert system, flood alert system, rain alert 

system, and fire alert system, emergency light system 

connected with sensor based alert system. 

The main purpose of the model is to bring the solution 

through various techniques by introducing formats by 

creating awareness programs providing required sources 

and to create proper guideline for the people of the 

society.

GEO THERMAL ENERGY 

AND ITS USES 

Scientific Principle : Thermal energy is converted into 


Objective : To get pollution free energy through this 

project of geo thermal energy. 

Descriptions : First of all a rectangular box (cuboids) of 

the old fridge was brought and then as requirement and 

specimen the box was prepared. Now the well was 

prepared and model was also so prepared that the steam 

came out from the bottom. Our main aim was to produce 

more steam and to achieve this aim we prepared a coilshaped 

web from the copper pipe. From it one connection 

was given into the well. A small copper pots were 

connected at different places. Our main requirement was 

to get more pressure. To get the heat a connection was 

given with gas. Now to allow the water to enter the 

connection from the big bucket was so given that the 

water supply could be increased or decresed. Though gas 

the water was heated and turned into steam. On getting 

the steam pressure the fan started moving and the electric 

current was also produced. This electric current was 

supplied to the LED bulb and purified water could be 

obtained. Thus using the wastage of the steam distilled 

water could be obtained

RADIATION HAZARDS 

AND CONCERNS 

Scientific Principle : To control the spread of radiation by 

changing fraction of neutrons that leaks from the system, 

various absorbers, adding or removing fuel from the power 

plant etc. 

Description : In this model, we have shown a typical 

nuclear power plant. The nuclear fission takes place in the 

core reactor. In the reactor shown here, ordinary water is 

used as moderator and coolant. Such a reactor is said to be 

pressurized water reactor. The reactor is controlled by 

control chamber. In case, the cooling system of reaction 

fails the radiation leakage is controlled by: 

* Adding or removing fuel. 

* By changing the amount of absorbers that competes with 

the fuel of neutrons. 

* By changing fraction of neutrons that leaks from the 

system. 

* Varying absorbers which are called control rods. 

* Water cannons can also be used as controllers. 

Description : Our intention is to aware people in general, 

about leakage – source – types of radiation(s), its ill effect 

(i.e. How are they causing transmutation, causing irregular 

cellular growth (tumor) etc.) in human being(s) & in 

animals. 

We also targeted at on various steps by which radiation 

exposure can be stop or can be Diluted, along with 

measures / treatment that must be given to a person 

explored by intense radiation.

FUEL FROM WATER 

2012 

SCIENTIFIC PRINCIPLE INVOLVED: 1.PEM (Polymer 

Electrolyte Membrane)Electrolyzer: Electrolysis involves 

simply running an electrical current obtained from solar 

cell through distilled water splitting the H2O into H2 & 

O2. The produced hydrogen gas is then compressed and 

stored for further use. 

2.PEM Fuel cell:PEM fuel cells use oxygen from the air 

and above pressurized hydrogen to create electricity, heat 

and water (steam) as byproducts. The above generated 

electricity then powers the electric motor, which in turn 

drives the front wheels of a car. 

MATERIALS REQUIRED FOR THE CONSTRUCTION: 

In our model, (1) Distilled Water (3) Solar cell (4) PEM 

Electrolyser (5) PEM Fuel Cell (6) D.C.Motor (7) Toy Car 

(8) Plastic H2 storage tank (instead of compressed metal 

tank) (9) Plastic O2 storage tank ( instead of air pump) 

WORKING: 1st step: By passing electricity through 

distilled water from solar cell in a PEM Electrolyser ,we 

get pure hydrogen &oxygen gas. 

2nd step: Hydrogen gas can be stored in a Pressurized tank 

with the help of a compressor in the fuel station and 

Oxygen gas produced is released into the atmosphere. 

3rd step: In a car refilling of hydrogen gas in the H2 

storage tank will be done from the fuel station. 

4th step:Hydrogen & oxygen gas(from air by air pump ) 

passed through fuel cell produce electricity. The 

electricity then powers the electric motor, which in turn 

drives the front wheels. Water vapour and heat are the 

only by products of the above process .

EARTH QUAKE ALERT SYSTEM 

DESCRIPTION 

2012 

MATERIALS REQUIRED FOR THE CONTRUCTION: Half 

Circular vessel of Aluminum. Iron pipe and stripes, 

Barring, Plywood's sheets, Solid sphere of conductor 

metal, bar magnet, Insulated wire , Siren, buzzer-2, 

Copper vessel, Spring, Weights, LED, Bulb (12V), 

Transformer-2,555 timer circuit-2, plastic jar. 

WORKING METHOD: When earthquake's waves come 

from any direction, circular vessel does parallet 

oscillation, so revolving platform's system rotate towards 

the direction and does parailel oscillation and also simple 

pendulum does oscillation and it touches metal stripes on 

the parth of motion so 555 timer circuit gets pulse, joined 

buzzer in out rings for two second and light in bulb. 

If there is heavy intensity earthquake, amplitude of simple 

pndulam increases, so mechanical switch takes “ON” 

position. Therefore 12V bulb shines and there is 

continuous siren. 

When communication section gets pules, earthquake 

message reaches to the message center. 

Construction-2: For earthquake's Vertical Oscillation : 

Make vertical oscillation stand with galvanize sheets 

spring and plywood sheet as shown if figure-2, make a 

structure of plywood rectangle, hang the spring on the 

structure's ceiling, hang proper weight with pin at another 

end of spring and contract simple harmonic oscillator. Fill 

electrolyte in conductor Bessel at maximum under height 

the pin. It should not touch to the pin. 

Due to earthquake's vertical oscillation spring oscillations 

up and down, so pin touches with electrolyte therefore 

timer circuit gets pulse, it makes relay switch on, so 

electric current flowers in output. As a result LED shines 

and buzzer rings for 2 seconds.

OZONE LAYER AND 

ITS ASPECTS 

Intoduction :- The ozone layer exists in the atmosphere 

surround the earth in spherical way. Each and everyone should 

know about the ozone, how important the ozone layer for the 

living on the earth; Everyone should know that. In what way 

people belong to the earth making harm to ozone layer; all 

should know that. 

What measures should be taken to protect the ozone layer! 

The measures must be known by us . . . by everyone . . . 

Scientific Principle: - 

Ultraviolet rays of the sun play important role in the creation of 

the ozone. (O2 + O = O3 ).Ultraviolet quantity of oxygen to 

protect the ozone layer is main condition. That can be carried 

out by growing more and more trees. Pollution must be at least 

level. 

Objective: - The ordinary and common man should know the 

importance if ozone layer. One should have awareness for the 

survival of ozone 

Description: - The main cause of hole in the ozone layer is 

manmade Organohelogen, atmicbromin atomicclorin, and 

Chlorofluorocarbon. 

Place a globe with stand just around the globe stay the iron-rod. 

Fix the butter paper with rod to show the ozone layer. This will 

clear the concept of ozone layer. 

With help of stand fix the umbrella above the second globe. One 

time hole will show the depletion in the ozone layer fix the torch 

to another stand. Torch light rays will show the ultraviolet – 

incident – on the earth – through the hole (depletion). 

Organ, Halogen gases, Pollution, Bromine , Chlorine create the 

CFC and BFC. How are they harmful and at what level? 

Grow more trees and be pollution free, so that we can protect the 

ozone layer for safe and secure living existence on the earth

VEHICLECTRICLE 

POWER SYSTEM 

Purpose :- 

* As an option of non-renewable source of energy, to use pollution 

free renewable source of energy. 

* To protect the environment by using pollution free energy 

sources. 

Principle:- 

* Conversion of the air into electricity. 

* Conversion of kinetic energy into wind energy 

1. Introduction 

i) Rationale Behind Construction Of The Exhibit: 

These vertical axis wind turbines have been installed in Nebraska, 

Texas and California in mid 2010. and expand at a rate of up to 5 

miles per month. Other states and countries will follow. In India we 

have 15 National express highways with total length of 636.19 km. 

In express highway 15 vehicle pass par minute. We can utilize these 

highways to produce vehicle power electricity. 

ii) The scientific principle involved. 

The scientific principle involved conversion of the air displaced by 

passing vehicles on highways into electricity 

2. Description 

(i) Material used for the construction. 

Plywood, toy vehicles, l.e.d bulbs., wind mills, electric motor, 

galvanometer, etc. 

(ii) Construction and working of exhibit /model; 

Construction 

2012 

A piece of plywood has been painted and made like express 

highway. Painted wood pieces have been fixed in the middle of the 

ply which looks like dividers. Vertical axis wind turbines have been 

placed atop these dividers at regular distance. For demonstration 

purpose these wind turbines are rotated with toy motors run by 

electricity from the Transformer. These turbines are joined with 

generators which produce electricity. The produced electricity is 

used to illuminate toll offices and pole lights on both sides of the 

road. Surrounding area are also providing this energy.

FARM SECURITY 

MACHINE 

Introduction India is an agrarian country. Due to 

irregularity of monsoon the harvesting is uneven. The 

cattle grazing also causes reduction in some total of 

agricultural product with this objective, the present 

project is under taken. 

Scientific Principle : Electric signal completes when 

infrared signal cuts off when circuit completes, current 

flows 

Objectives : To save the Crops 

Description & Working Mechanism: First take a piece of 

hard board, then make it like a farm, place the sensor at 

both end of the farm, and connect circuit at one end. Take 

out two wires from the transformers and connect circuit 

with it and take out another two wires and attach it with 

tungsten wire and make a coil so crackers can blast. In 

farm at one place but siren and light up the bulb and at 

other place arrange rain censor with other circuit. Besides 

it, make an arrangement to dry the crops. Arrange PVC 

pipe on this arrangement as per shown in figure. Now 

attach electric motor with pipe, And fix the “ tadpatri ” on 

pipes like curtains. Than connect motor with circuit 

After applying this mechanism in farm whenever swine 

and other wild animals enter in farm, the infracted sensor 

cuts of and the attached circuit will play the Siren and 

light up the bulb and further at the other end the crackers 

will blast so that the swine and the other wild animals run 

away and so even if the absence of farmer this system 

helps farmer to loss of his crop when he scattered his crop 

for drying or attached with it activated automatically and 

as per the pre-arrangement of the “tadpatri” and so that 

the loss of crop can be prevented.

MANGROVE - BLESSING 

FOR ENVIRONMENT 

2012 

The scientific principle Mangroves produce negatively 

geotropic and positively phototropic aerial roots from their 

under grounds roots. These roots are spongy long and 

possess a large number of lenticels. Sufficient oxygen 

reaches the under ground root system through these 

lenticels. 

Description: (i) Materials used for the construction: 

Mangrove Plants, Breathing roots, seeds, soil, mud, salt, 

map of Gujarat, photograph and charts, laptop, fodder, 

tray, bucket, water etc. 

(ii )Construction: Take 5-10 germinated seeds of mangrove 

(Avicenia marina)-drop it vertically straight into the 

muds,it becomes enchord. Leteral roots develop and 

proper establishment is achieved. After few days 

breathing root also developed. 

Now take plywood 4”x 4”.Draw a map of Gujarat on it. 

Show coastline on the map and mangrove plantation. 


211

NATURAL AIR 

Scientific Principle: Coal is efficient to reduce the heat of 

the normal temperature water. 

Objectives: Coal is natural filter of any type harmful 

particles. 

Description: In the model an upfront exhaust fan is start 

with connected of 12walts battery. The fresh air from the 

outside is sucked by the upfront fan. Now the pump will 

be on and the water is transform to the Shower from the 

bottom. This water is showered from the top and getting 

on the coal and also cooled the air which sucked by the 

top fan. This showered water get collected at bottom and 

again pumped to upward so this cycle is running 

continually. So the air is getting cooled. Now this cooled 

air vacuumed by exhaust fan from the copper pipe and 

spread it in the house. So the inner temperature of house 

will be more than 5 degree low then the outside 

temperature and we will get the Air condition effect. 

Our main purpose of the model is not produce chloral 

floor carbon and ammonia gas. So, we do not create any

POLLUTED WASTE WATER 

RECYCLING AND REUSE 

Scientific Principle:- Recycle of water by centrifugal and 

centripetal force then followed by chemical treatment to purify 

it. 

Objectives:- Reuse waste water after recycling to overcome 

commercial water demand. 

Description:- Materials used for construction:-Hard board, boxes, 

thermo coal, p.v.c pipe, small electric motor, small tube, 

adhesive, funnel etc. 

Construction:- From different area drainage line joined with 

main drainage line and this main drainage line joined with Suez 

farm .From this Suez farm line joined with well where turbine 

and small size sieves funnel is situated .Further this well a 

connection is given to small well where chemical treatment is 

given and it is join with the water storage tank and water taken 

up by pump where chlorine treatment is given .Then water is 

used for different commercial purpose from storage tank. 

Working of the model : From different area main drainage line 

joint with Suez farm. From there solid wastes are distributed and 

underground for making Suez fertilizer. The rest of water 

without solid waste take into the well where turbine and small 

size sieves funnel is situated. When the turbine is “ON” due to 

the centrifugal force/centripetal force of turbine the wastage will 

settle down in the bigger well due to turbine rotation aeration 

will allow oxygen to dissolve in water. The rest of water passes 

through the funnel and will go to the small well where chemical 

treatment is given. The rest of purified water taken into water 

storage tank by pump in this tank chlorine treatment is given. 

Storage water used for commercial purposes. By this way geo 

water level maintain for longtime. 

Applications: 

2012 

— Recycled water used for Agriculture, plantation, grow of 

tree and etc. 

— For industrial, construction purposes. 

— Water conservation by not using drinking water for all these 

activities.

an electric circuit with a belt to a motor. We connected 

different sensors of temperature, flood, earthquake, fire 

and tsunami with the electric circuit. the circuit run with 

the battery. 

Working:- In this our project, most important work is the 

electron control circuit. The various sensors which are 

connected with this control circuit and enable to switch 

off the nuclear reactor automatically at the time of any 

problem or accident and turn-on the emergency alarm. In 

this type of project protection system , sensors of 

temperature, flood, earthquake, fire and tsunami have 

been secure from other sensors. This project runs with the 

battery. So, at the time of any accident or calamity like 

earthquake, tsunami etc. The plant takes necessary 

electricity from the battery. It prevent from any major 

accident. There are sensors at the border line of the 

nuclear power station which recognize the terrorists and 

restrict them to protect the plant

ECO FRIENDLY BOAT 

Introduction:- To save sea-creatures and stop water 

pollution 

Theorm :- The liquid which has less density, swims on the 

layer of water 

a) Rationale behind construction of the exhibit :- To 

make this subject Science and Technology for challenges 

in the life possible or turn into reality, save sea-creatures 

and stop water pollution; this instrument is made-called 

ECO FRIENDLY BOAT. Sometimes while transportation of 

crude oil from one place to another; by accident in ship or 

pipelines leakage crude oil spreads into sea and causes 

water pollution and sea-creatures die. 

b) Description :- Materials –electric motor, batteries, 

wheel(CD), cable extension, boat, plastic strip, oil, vessel, 

hair-boom 

Construction: - In this instrument, on the back side of the 

boat ; a big wheel(CD) falling into water is fitted. The 

wheel is refitted by an electric motor. So crude oil sticks 

with the wheel. The wheel comes into direct close contact 

with tunnel (Plastic Strip) around it and fractioning 

between wheel and tunnel; crude oil is collected in a 

vessel placed into the boat through tunnel. Thus, water 

pollution can be avoided and save sea-creatures' life and 

get crude oil back. 

c) Application: - With the use of this instrument six liters 

oil can be get back, spread into water within an hour. 

That's the specialty of this instrument.

ELECTRICITY THROUGH STAIRS 

Introduction: - 

Walking is the most common activity in day to day life 

when a person walks; he loses energy in the form of 

vibration. This energy can be tapped and converted in the 

usable form. In order to develop a technique to harness 

foot step energy, a foot step energy generating device is 

developed. The steps are provided with coil and magnet is 

placed below it. Depending on the weight of the person 

and the frequency of steps the electricity is produced. As 

soon as the person put step on the stairs the bulb glows 

and remains lights up when the battery reaches its full 

voltage. 

Objective:- 

nd 


Exhibition 

& Project 


To produce electricity through steps and consume it 

commercially. 

Working: - It is based on the principle of 'Electromagnetic 

Induction'. When electric field around an electromagnet is 

increased or decreased. An electric current is induced in 

nearby circuit. 

Cause of induced current: - 

The current is induced in a coil when magnetic flux 

linked with the coil changes with time. 



Aims: 

To be able to operate the machine safely and correctly in 

accordance with the manufacturers hand book and 

accepted good practices; 

Be able to operate the various attachments and safely sling 

and manoeuvre a variety of loads using the machine and 

understand the signals given by slingers/banksman; 

Clearly understand the causes of instability of the 

machine, its carrying vehicle and the loads carried; 

Be able to carry out a routine pre-use inspection of the 

machine and its attachments. 

Objective: 

The objective of this project is to design and implement an 

experimental hydraulic system that simulates joint 

flexibility of a single rigid link flexible joint robot 

manipulator, with the ability of changing the joint 

flexibility's parameters. Such a system could facilitate 

future control studies of robot manipulators by reducing 

investigation time and implementation cost of research. It 

could also be used to test the performance of different 

strategies to control the movement of flexible joint 

manipulators.

SEISMOGRAPH 

We know that the earthquake on the earth is caused by the 

disturbance deep down inside the uppermost layer of the 

earth. This layer is fragmented into pieces. Each piece is 

called plate. These plate are in countinued motion. When a 

plate goes under another due to collision, they cause 

disturbance in the earth's crust which shows up as an 

earthquake on the surface of earth. 

The power of the earthquake is expressed in terms of a 

magnitude on a scale called the Richter scale . Really 

distructive earthquake have magnitudes higher than 7 on 

the Richter scale. 

The earthquake produces waves on the earth's surface. 

These are called SeismicWaves. Thesewaves are recorded 

by an instrument called the Seismograph. 

Seismograph :-- 

It is simply a vibrating when earthquake occur . A pen is 

attached to the vibrating system . The pen records the 

seismic waves on a paper which moves under it by 

studying these waves scientists can construct a complete 

mape of the earthquake . 

They can also estimate its power to cause destruction. 

Protection Against Earthquake :-- 

Although it can not be predicted, we can only take 

necessary precautions to protect ourselves all the time . 

1. Consult qualified architects and structural engineers to 

make buildings . 

2. In highly seismic areas uses of mud and timber is better 

than heavy construction materials . 

3. It is better if cupboards and shelves are fixed to the 

walls, so that they do not fall easily . 

4. All the tall buildings should have fire fighting equipment 

in working order . 


RAILWAY TRACK CHECKING 

MACHINE CUM 

SECURITY TRACKER 

1. Railway Track Checking:- 

v Now a day's most of the train accidents are caused due to 

cracks in the railway line. 

v Railway track checking machine works to check the railway 

tracks whether they are safe or broken. 

v The machine is fully radio controlled and it gives live video 

of the railway track, which it is checking, along with this it also 

gives us all voices that arise on/near the railway track. 

v It is embedded with several sensors which help it to check 

out the cracks on the railway line, the machine has a red signal . 

If the machine senses any crack on the railway line then the 

signal can be made red and intimate to the control room 

immediately. 

v A GPS system can also be used in the machine which is 

operated by 24 satellites placed in the orbit by U.S. defence 

Government. The GPS system works anywhere, in any weather 

conditions, 24 hrs a day, with the help of GPS we come to know 

the actual position of the machine where(at which place) it is 

working. 

v If the machine detects any cracks on the railway track then a 

bell rings in the control room which doesn't stops ringing until 

any one stop it. 

The objective of the machine is to prevent train accidents caused 

due to cracks in the railway line. If the machine detects cracks 

then through railway control room we can make the railway 

signal red and also inform the railway drivers to stop the train 

running on the defective track. Through this machine we can 

save lives of thousands of people. If the machine is used by the 

government then the machine can be made much better than it is. 

2. Security Purposes:- 

v The machine may also be used by the police/Army personals 

to find out and listen the conversations of terrorists/anti social 

elements. 

v Through this machine police could know about their 

plans/No. of persons involved and type of weapons are used in 

the crime.

& ROAD MAINTENANCE 

AIM:- To solve the major problem in India which is shortage of water & to 

increase the ground water lever by rain water logged on roads during rainy 

season & to also save water future generation. 

SCIENTIFIC PRINCIPLE INVOLVED:- 1. The Rain water which is collected 

on roads in low level areas can be drained out with the help of small 

pipelines & can be fed into large harvesting pits from where it can be used for 

irrigates. 

2. The water presented in ponds or wells in villages can also be purified by 

mixing medicines like potassium permagent or can also be purified through 

large purifiers & then can be further used for various purposes. 

SCARCITY OF DRINKING WATER UTILITY:- This project helps us to solve 

two major problem of our country. These two problems are scarcity of 

drinking water and damaging of roads during rainy season. 

SCARCITY OF DRINKING WATER:- Our country is facing a big problem of 

drinking water. On Analyzing the current situation it seens that bultion next 

10 or 15 years so many people will die due to non-awailibetety of drinking 

water. Now also water are many places where peoples are hunger for even 

singal drop of water. It does not that nature doesn't gives us water. It gives us 

lot of water by raqin but we don't preserve that. Most of the water drain out 

and ultimately reaches to sea. So if we only conserve 50% of the then also we 

can solve the problem of scarcity of water. We can store this water 

underground. In grounds there are so many big tanks provided by nature. If 

we will fill them with water, then we can use that water for whole year. 

DAMAGING OF ROADS IN RAINY SEASON:- One more problem is the 

damaging of roads during rainy season. In rainy days a lot of water 

accumulates in low level areas which is the main cause of damaging of roads. 

It also adversely affect the traffic of the city. 

Our project solves two problems. Actually in most of the cities drainage 

system is not proper which is not able to drain the water of low level areas. 

So, rain water accumulates in these areas. 

USES OF WATER:- 

nd 


Exhibition 

& Project 


1. The water filtered can be further used for cooking bathing, washing. 

2. This water can be used for irrigates purpose. 

3. this water can be used for grneratim of electricity. 

4. Water stored can be supplied to these areas where there is scarcity of water. 

5. The Water Harvested is very useful in increasing ground table. 

FURTHER SCOPE OF THE PROJECT:- If this project is adopted by 

government of India then we can solve the problem of scarcity of water as 

well as we can protects or roads from damaging. 


CHEMICAL SNOW FALL 

Aim: Chemical Snow Fall. 

Requirement: Close container, Chinadish, Stones, Burner, 

Tripoid stand, Phthalic acid, Matchstick etc. 

Principle: It is based on sublimation process. 

Theory: Sublimation is the process in which solid 

substance directly changes into vapours. In this project 

phthalic acid is used. 

Chemical formula of phthalic acid is C H (COOH) and 

5 4 2 

chemical reaction takes place in this process as indicated 

in the figure. 

Construction: 

Working: When we heat phthalic acid in chinadish it 

starts to change into vapours. When vapours of phthalic 

acid falling on stone placed in closed container, appear 

like snow. 

Application: (i) It is used to create artificial condition of 

snow fall in those areas where it is not possible by nature. 

(ii) It is used for decoration purpose in parties and other 

programmes.

· Water heating 

Working: 

nd 


Exhibition 

& Project 


The device consists of 2 water tanks which have their 

respective inlets and outlets. The water in the storage 

tanks gets heated by the fire beneath it in around 20 

minutes. By the time the water gets heated ,the fire can be 

used for cooking purposes. The coal and the hot ashes get 

collected in the tray and can be used for roasting. The 

gases released on burning are expelled through chimney. 

This device is “A Boon for High Altitude Areas” areas as it 

can also be used for space heating i.e. it warms up the 

area surrounding it. When the steam starts coming out of 

the steam outlet, then the hot water can be taken out from 

the tank and the steam can be used generating electricity. 


ELECTRICITY PRODUCED BY 

NATURAL RESOURCES 

By this innovative idea we are able to convert different 

forms of energy i.e. wind energy,solar energy,frictional 

energy, mechanical energy into Electric Energy. 

Requirement of electricity is increasing day by day. Non - 

Renewable sources of energy like coal, petroleum etc. are 

limited .So the idea comes to prevent the non renewable 

resources and generate electricity from renewable sources 

of energy. Wind energy ,solar energy are good resources 

which would exist as the universe exist.In this model 

some ways are shown like using wind energy ,Solar 

energy and mechanical energy etc. This project is totally 

based on future demand and will be very helpful or we 

can say very useful also in future. 

Save Resources,Save Energy”use this model to make 

energy'

Human civilization's energy consumption is growing. At the 

same time, the harmful environmental impact of our energy 

usage is becoming apparent. A massive global effort to adopt 

renewable energy has begun. We must use Earth's resources at a 

rate at which they can be replenished, and thus provide for 

future generations to live as we have. 

Solar Energy – To Generate Cheap, Green Electricity As long as 

the sun shines, life on our planet can be supported. It can be 

used for Lighting and heating the House. 

Wind Energy : Wind can be used for specific tasks such as 

grinding grain or pumping water or a generator can convert it 

into electricity to power homes, businesses, schools etc. 

Rain Water Harvesting System 

It simply means catching and holding rain where it falls and 

storing it in tanks or to recharge groundwater. 

Water Purification- Obtaining fresh water from salty or impure 

water by evaporation and condensation. 

Green House- Green houses can be used to create conditions 

suitable for plant growth even in the harshest conditions. 

Composting- Wastes are nothing but misplaced resources. A 

large volume of organic matter is generated from agricultural 

activities, dairy farms and animal shelters which can be utilised 

by properly by composting it . 

Refrigeration & Air Conditioning- While evaporating water will 

make its surrounding cooler by extracting heat. The Air 

conditioning system and Refrigerator is based on this principle. 


BIOFUEL FROM ALGAE 

A Brief Write-up on the project 

Theme: Energy generation and conservation 

Topic: Biofuel from Algae 

Objective: To replace non-renewable sources of energy 

Concept: This project explains about algae as a resource 

for replacing fossil fuels which are non-renewable. It has 

been found out that some species of algae can metabolize 

sugar into lipids. These lipids if extracted can replace 

fossil fuels without changing engines due to similar 

composition. 

Procedure: Algae can be cultivated on non-potable water 

and their growth is very fast. Algae biomass is collected, 

dried and then sent to processing unit. Here, oil is 

extracted from biofuel and other separated part is supplied 

to cattle farms for feed. In this way algae are 100% useful. 

Advantages: 

· Energy is produced which can replace fossil fuels 

· Purifies environment as algae release O2 during 

photosynthesis 

· Also provides fodder for cattle's 

Future Scope: 

· Tries to conserve non-renewable energy 

· Provides better environment and can control green house 

effect thereby controlling global warming

BEST OUT OF WASTE 

A. Introduction. 

These days disposal croceries made of Thermocol is used 

in marriage parties and other functions. After using it is 

either thrown as wastes or burnt. We get waste petrol after 

washing the various parts of the engine with petrol during 

the service of the vehicles. Both types of waste materials 

cause air pollution as well as soil pollution. We have 

developed a technique to prepare a very useful adhesive 

from these two waste materials. It can save environment 

from the pollution. 

B. Method of Preparation: 

Take some waste petrol in a beaker. Then put waste 

thermocol in to it. When the petrol will stop to absorb 

more thermocol we will get a paste in the form of 

adhesive. We observe when petrol and thermocol are 

mixed, no reaction take place. 

C. Benefits: 

This paste can be used as a powerful adhesive to stick 

tiles, marbles, granites, furnitures, puncture of tyre-tubes 

and in Rubber industries. 

D. Cost: 

This adhesive can be prepared by this technique at a very 

low cost.

Solar Water Heater is a device which is used to heat water 

by utilizing solar energy. 

Construction- A Solar Water heater essentially consists of: 

1. An insulated box painted black from inside. 

2. Copper tubes which are fitted in the form of a coil 

inside the box. The copper tubes are also painted black 

from out side. Black painting is done so that heat rays 

from the sun are absorbed more efficiently. 

3. Glass Sheet cover is used as lid and it produces the 

green house effect inside the device. It means the glass 

sheet prevents the escaping of heat out of the device, after 

it once enters that box. 

Working: Freshwater which is cold comparatively is made 

to enter into the storage tank through the opening. From 

the tank it goes into the copper tubes through connecting 

pipes. These copper tubes are heated by absorption of 

solar heat energy and cold water inside the tubes also gets 

heated. The hot water in the copper coil goes down. Hot 

water can be taken out for use with the help of outer pipe.

MULTISTOREY FARMING/ 

PLANTATION 

With agricultural land under pressure from climate change, soil 

erosion and increase in population , there is an innovative 

solution to create “vertical farms”, in or near cities that could be 

used to grow food. This practice can be done on a large scale 

which will help in warding off starvation and provide food 

security. 

If successfully implemented, they offer the promise of urban 

renewal, sustainable production of safe and varied food and the 

eventual repair of the ecosystems that have been sacrificed for 

horizontal farming.With that in mind, multi-storey farms located 

in the heart of cities have been touted as a wall to minimize land 

use, reduce emissions from transport and make regions selfsustainable. 

In recent years, floods, droughts, wildfires and 

pollution have devastated traditional harvests and in many 

cases, it is expected to get worse. India's agricultural output for 

example, is predicted to diminish by 30 percent by the end of the 

century due to changing rain patterns. Not just that, but 

mankind is rapidly running out of land to grow crops due to a 

rapidly growing population. For these reasons, inner-city farming 

makes sense. Also known as Vertical Farming, it would see high 

storey buildings turned into high-rise meadows. A vertical farm 

would also behave like a functional ecosystem. If each one of us 

starts using it, then this would lead to less pollution as the CO2 

of major cities would be absorbed by the abundance of plant-life 

being grown. 

· A sustainable way of farming for the urban and rural areas. 

· It mitigates the problem of natural calamities like drought & 

drought like conditions. 

· Indoor utilization of space which also gives an aesthetic look 

in case of pocket farming. 

· An economical way of food farming which can provide food 

throughout the year. 

· Multistorey farming is a blessing for the landless. 

· In desert areas or in excessive saline land areas, it is actually a 

boon. 

It is a futuristic way of farming which will help in promoting 

environment friendly ways

COOL ROOF-HEAT PROOF 

— Introduction: Most of the people in countries live in 

urban areas. Across the world, air temperatures in urban 

areas have increased faster than air temperatures in rural 

areas. Cool roofs seem to be an ultimate solution. This 

report summarizes the results of a detailed monitoring 

project done in school in order to understand the 

importance of cool roofs. The related results are being 

analyzed and conclusions drawn. 

— Aim and Methodology: The basic aim of this project 

was to prepare a model to show how effective it is to paint 

the roofs of the building or houses with light colours 

especially white so that the house is kept naturally cool. 

Two rooms with similar specifications were constructed 

adjacent to each other at a place where they are equally 

exposed to sunlight. One of the roofs was left without any 

paint and the other room was painted white on the roof 

and also on all the sides. Two measuring thermometers 

were installed in each room and readings were noted 

down every day at 1:30 pm for about two months 

Analysis of the result: After taking results the results were 

analyzed and there was a drastic difference in the internal 

temperature of the two rooms. 


PARABOLIC SOLAR COOKER 

Title: Working model to conserve the natural resources by 

making use of solar energy 

Aim: To utilize solar energy for heating and cooking in 

order to conserve the natural resources 

Principle: Converging the solar energy to a point using 

reflecting surface 

Features: 

—Temperature reaches to as high as 150°C 

—Reduce the consumption of fossil fuel like oil, gas or 

coal 

—Environment friendly 

—Low cost renewable energy resource 

—Economical 

—Solar cookers provides healthier food because of slow 

heating 

Working: 

When the solar radiations are incident on the parabolic 

reflector surface , after reflection they converge at a point 

known as FOCUS. The reflectors are joined to form a 

parabolic surface to concentrate radiation. When the food 

is cooked in the cooker then the pressure build inside it 

give rises to steam , which in turn can be utilized to run a 

turbine and hence generate electricity.

GEO-STATIONARY 

SOLAR COOKER 

This Model Geo-Stationary Solar Cooker is an improved 

version of solar cooker which can freely rotate in the 

direction of sun at the same speed by mechanical means. 

Solar cooker is mounted on a platform fitted on stool with 

the help of ball bearing. The base of platform is tied to a 

thread which runs over pulley and tied to a small bucket 

or mug. In this bucket, drop wire drop water is allowed to 

pour, by the weight of this drop by drop water, the whole 

system rotates and hence solar cooker also. The speed of 

rotation is controlled by regulator of water gulucore pipe 

as 15-20 drops/minute and the solar cooker rotates 4 

degree/minutes or 15°/hour and meal is prepared normally 

in three hours. 

Further the temperature of inside solar cooker is also 

continuously measured by fiting athermo meter within 

wooden solar cooker.

FIRE ALARM 

Fire Alarm is a device which controls fire. This tells us 

about the controlling of fire when it is not controlled. The 

Model shows a house which cought fire due to some 

reasons. In it I tried to show how to control fire. When the 

flames rises, the heat energy of the house increase. 

A sensor fitted in it senses the fire and convert the signal 

of heat energy into electrical waves sends message to the 

bell to ring. A water pump connected to the bell starts 

working and showers water in and on the house and the 

fire is under controlled. 

It is a representation with which fire alarm works. In it the 

bell works with the electromagnetic force which is 

produced by the two magnets. The charged bodies 

produced electromagnetic force between them which is 

36 

10 times stronger than gravitational force by 

electromagnetic force the bell rings. This device is useful 

in houses, shops and industries etc. 

When fire alarm is in chemical industries, the system is 

changed by fire extinguisher in place of water. When there 

is no electricity in the house, we have to connect 

electromagnetic for the conduction of electricity. This is 

all about the fire alarm.

HYDRO-ELECTRIC 

POWER PROJECT 

Hydro-electric power is a form of energy i.e. renewable 

resource hydro power provides about 96% of renewable 

energy in the country. Hydro power comes from flowing 

water from mountain streams. 

Principles: In hydro electric power potential energy of 

water is utilized to generate electricity. To generate 

electricity water must be in motion this is kinetic energy 

when flowing water turns blade in a turbine. The form of 

change to mechanical energy the turbine generate the 

electricity, turns the generator which then turns the 

mechanical energy into electrical energy. 

Transmission of energy: Once the electricity is produced, 

it must be delivered to where it is needed-out home, 

schools, offices etc. when in use electricity produced by 

dam system, do not produce green house gases. They 

developed the atmosphere. Hydro power is able to 

produce peaking power load following and frequency 

control helps protect system feature. That could lead to 

the damage of equipment and even blackout.

DRIP IRRIGATION/ 

MICRO IRRIGATION 

Water is very important investment for agriculture. 60% of 

water is wasted in the conservation method of irrigation 

due to one reason of the other. Water wasted due to run of 

or percolation out of root zone are the main reasons. Apart 

from this water is also wasted during its transportation 

from its source to the field. We have to use water 

judiciously so that in future this scarce commodity can be 

saved for the future generation micro irrigation of water is 

the most suitable remedy to this problem. 

This is a new technique of irritation in which water is 

supplied in a planned way to the plants according to the 

requirement on the surface of the soil or in and around the 

roots of the plants. Light and repeated irrigation is done in 

the roots area to provide proper moisture. As a result, we 

get more production with less supply of water if every 

field of our country is irrigated by this method we will 

definitely we having 2nd green revolution in our country. 

Even Government is very keen in this micro irrigation 

project and is giving 80% subsidy to the farmers under 

Pandit Dean Dyal Upadhyaye Kishan Bagwan Smridhi 

Yojna.

It is important and logical question that why we selected 

this project only. As there are many other alarming 

problem as you all know that today world is facing many 

hazardous problem. There are many such problems which 

we can see in our day-to-day life. The two major problems 

arising in todays (1) water scarcity (2) Electricity cut. How 

can we stop there misuse or what best strategies. How can 

we have to make a keep control over all this. So to sol the 

problem of water scarcity and energy crises, we chose this 

project. In this project we have given some tips and 

solution to solve these problems to great extent.

Project of Bio diversity title present past and future. In this 

project we will show that biodiversity is decreasing day by 

day. If we do not conserve biodiversity in future, 

biodiversity will be lost so we should pay more attention 

to preserve our biodiversity for future. In this project we 

will show three features of biodiversity i.e. biodiversity in 

past, present and future. We also focus to pressure our 

biodiversity in future by accepting eco-friendly 

conditions, minimizing consumption of oil, electricity, 

pesticide and also by obeying three R'5 principles i.e. 

reduced and re-use and recover. More stress on organic 

farming and give space to specis which are threatened to 

recover.

LAND MANAGEMENT CUM 

ECOFRIENDLY COMMUNITY 

One of the main objectives of this project is to built a 

colony on uncultivable piece of land, and to minimize the 

use non-renewable sources of energy. This will lead to 

conservation of non-renewable sources of energy and this 

is the ultimate need of today and tomorrow. By installing 

Rain water harvesting system on the top of the colony, 

solar system and wind mill structure. All of them will 

help us in the protection of out environment hazards 

caused due to heavy use of coal, petroleum and electrical 

machineries. 

This project will also help us in environment protection 

and compel us not to cut the trees. Because trees are the 

backbone of out environment. By installing rain water 

collecting structure it will preserve and protect our natural 

water resources which are going to diminish day by day 

and some part of energy we can get by installing wind 

mills. Some percentage of energy need we can fulfill even, 

radio, mobile charging and torch charging can be done 

with wind mill without having any electric circuit in case 

there is no power we can charge our mobile phone can 

listen radio and charge cell.

Our project is on production of electricity on small scale 

to large scale from Biomass. The biomass used for 

electricity production will be obtained from the 

agriculture waste, remains of crops, coconut slevs husk, 

saw dust etc. These all biomasses constituents after 

complete combustions in combustion will be used for 

boiling water in boiler. The steam produced from boiler 

will be used for moving turbine connect to dynamo. 

Result is biomass electricity. Out project is carbon neutral 

because the carbondioxide produced will again absorbed 

by the plants and vegetation against which we grow again 

and again.

NEW ERA RENEWABLE 

SELF SUFFICIENT 

ENERGY HOUSE 

New Era Renewable Self Sufficient Energy House means a 

house which can produce all its necessary things like 

water, electricity, water for irrigation, purification of water. 

When the rain falls on the roof of the house, it will get 

collected in the funnel and from the funnel water will go 

into the bottle. As we know that there are two types of 

resources, these are renewable and non-renewable 

sources. Renewable sources those sources which cannot 

be renewed easily like wind energy, water energy, solar 

energy etc. Non-renewable sources are those resources 

which cannot be renewed very easily like petroleum, coal, 

natural gas etc. renewable sources are also called nonconventional 

sources of energy. Non-renewable sources 

are also called conventional sources of energy.

The aim of my project is to show how we can reduce 

carbon emission, save water with efficient low cost 

technology. Due to over population there is severe 

shortage of water. So rain water harvesting is useful for 

irrigation purpose. In my model zero carbon house means 

in modern technology we should use solar energy in our 

villages and house, drip irrigation and use of simple 

instrument tensionmeter by farmer. This transmeter 

measures moisture in the field. This type of transmeter 

work on simple principle, the suction pressure. I took 

simple plastic tube with porous end at one side and small 

capillary tube at the other end. One open end of the tube 

is put into small vial having mercury. Fill transmeter with 

water when soil is saturated with water, we can stop the 

irrigation. Use of lime soil helps in reducing the / OH of 

acid soil and enhance crop production use of liquid 

fertilizer with drip also helps in small amount of water 

use of solar cell efficient water saving technique and 

biogas is myzen carbon house.

PRODUCTION OF 

ELECTRICITY USING 

WIND MILL 

The project is based on the principle of conservation of 

energy. Here wind energy is converted into electrical 

energy for producing a potential difference of 3 to 8.5 

Volts in the form of D.C. and this output is used in various 

ways to operate Radio receiver for producing light using 

L.E.Ds. to operate a miniature ceiling fan and for charging 

a cell phone of any brand. Moreover the output voltage 

may also be used to operate a wall clock. 

This miniature model can be used on the top of the 

vehicle for production of electrical energy. A little 

modification for moving a turbine may be the exerciser 

(cycle) to charge the battery which can give power to 

operate some appliances like torch, cell phone radio 

receiver etc. 

This may be useful in areas where electric supply fail for 

many days due to heavy rainfall or other adverse 

conditions for power supply intruption etc.

My Model is an ideal home with multi purpose 

functioning in terms of fishing, water harvesting 

maintaining the level of green house gases. This home 

design which provide light in all rooms through a single 

bulb one fan is sufficient for the whole home. So it is an 

energy conservating home. 

The water harvesting system is so efficient which can 

provide too much amount of water for irrigation, drinking 

as well as for fishing purpose. The energy which is 

provided in the house though solar system is filled on roof 

of home. 

Therefore, it is an ideal home as per my model which is 

work in condition explain on the above facts so I suggest 

that this model can be application in the country for the 

conservation of energy as well as for water.

WATER WASTE 

MANAGEMENT GEOTHERMAL 

ENERGY 

My Model is based on waste water management in the 

coastal regions of India as well as on production of 

Geothermal energy. As we know that the core of the earth 

produces much heat and it automatically increases the 

temperature of the water present in water reservoirs. We 

can utilize that water to produce electricity with the help 

of the steam of that water the remaining condensed water 

can be used for the purpose of irrigation and other 

household uses. 

2nd phase of the model is based on the production of 

electricity with the help of saline water. When high tide 

occurs on the coastal regions of the country, we can 

collect the water of the tides and we can made electricity 

with the help of that water.

The satellite in low earth orbit moves with the speed of 

27360 KM per hour and takes only 90 minutes to 

complete. One revolution around the earth. So think about 

the current obtain due to relative motion between coil and 

magnet shaft (of generator) which moves with the speed of 

I.E.O. satellite i.e. about 27360 KM per hour. 

So we construct a power house in L.E.O. In this power 

house we install two type of satellite in low earth orbit. 

1. Generator loop satellite (GLS) 

2. Generator shaft satellite (GSS) 

1. GLS: Satellite will be static and these satellite have 

large loop of conducting material and also have super 

capacitor to store the produced electricity. 

2. GSS: These are made of magnetic material and should 

be installed in such a way that more in the loops of loop 

satellite with very high speed of 27360 KM per hour and 

work as the shaft of generator. As the speed is very high so 

it will produced about 90 times more electricity which is 

produced by the power house on earth.

directions without any change. Hydraulic Crane based on 

the principle of conservation of energy. The energy 

provide to the load is always equal to the energy given to 

the crane and it is proportional to the force and length of 

the crane. The output energy is roughly kept equal to the 

input energy of the crane. Some sort of energy is changed 

by friction in the experiment. The pressure applied to the

FIRE ALARM 

When fire starts in a house due to natural or man made 

causes, the two metal plates on the sensor expands due to 

heat and touch each other. This sensor is connected to a 

control panel which firstly switch off the electrical supply 

of house. At the same time it switch on alarm pumping 

mechanism and exhausts system. Alarm start ringing and 

alert people about fire. Pump starts pumping water on fire. 

It trys to control fire. During house fire, lot of smoke is 

produced, which is harmful, if in hold, So exhaust system 

takes out the smoke. Thus, save life of many people. So, in 

short, this system alerts people about house fire and also 

stops house fire automatically.

Objective: To highlight the seriousness of the problems 

and suggested solution to avoid any damage and flood and 

earthquake disaster situation. 

Principle: (1) Archimedes Principle: A body immersed in 

water or any other fluid will displace a volume of water or 

fluid equal in weight to the immersed body. 

(2) Function of springs: When a spring is compressed to 

stretches, the force extend is proportional to its change in 

length. Therefore it avoid the jerk to the house at the time 

of earthquake occur. 

Working: While constructing floating house firstly four 

rigid cylindrical iron pillars are erected in concrete 

foundation into the land. On these four pillars four hollow 

pillars are fixed with the minimum gap in between and 

with the support of these hollow pillars. The base of the 

floating house which is anti earthquake because of four 

high strength springs are fixed on the four rigid pillars in 

hollow pillars for its flexibility and separated from land is 

made like a small flat boat. The house is constructed on 

the base with hollow and light weight concrete blocks so 

that the weight of the house is less. Therefore, this type of 

house could be successful also to construct where the 

people face the problem of submerging their land 5-8 feet 

for 5 to 8 months in water due to dam reservoir like 

govind sagar and pog dam constructed in order to produce 

electricity in Himachal Pradesh and other States also.

EFFECTS OF MOBILE PHONE 

SERVICES ON ENVIRONMENT 

& HUMAN HEALTH 

Man has become addictive of usage of mobile phone without 

taking into consideration the various fatal effects which this 

technology is producing in terms of environment, health and wild 

life which are even not be recoverable in the coming generations. 

The brief description of these effects is detailed below. 

Effects of radiations emitted by Mobile Phone Towers on 

environment: 

Our natural world is under assault from human activities. With 

emerging technologies particularly in the field of mobile 

communication has effected in a worst way to not only wild life 

including bees and fishes but also fauna and flora. Some of the 

species of birds and animals are at the verge of extinct. 

Cell phone like other technologies do contribute to climate 

changes, because the fossil fuels used to provide energy to charge 

them and make them run properly when burnt to provide them 

power do release carbon dioxide and other green house gases 

,which retain the heat of sun instead of reflecting away from earth, 

which in turn increases overall temperature of earth. 

Effects of radiations emitted by mobile phone /Towers on Human 

Health: 

There has been a significant increase in mobile users in the recent 

years, increasing it to 929 million mobile users in India up to May, 

2012. This significant increase in users also increases of mobile 

towers, this increasing usage and more towers affects human 

health giving birth to lot of diseases like: Blurry Vision, Headaches, 

Nausea, Fatigue, Neck pain, Memory Loss, Leukaemia, Rare Brain 

cancer, Enzyme changes that affect DNA, Birth Defects, Changes in 

Metabolism, Increased Risk for Heart conditions/Pace makers, 

Neurological Hormone Changes linked impaired brain Function 

CONCLUSION : From all the above noted details it is quite clear 

that the usage of mobile phone is in one way or the other 

hazardous for Environment, Human beings, Flora and Fauna. Man 

for fulfilling his own deed of connect at any place any time is 

putting himself and the whole nature at stake. Therefore, we 

should use your mobile phone judiciously. If at all animals and 

plants would have been able to convey us their feelings they 

would have said “Man Live and let us also Live”.

USE OF RENEWABLE 

ENERGY RESOURCES 

Model is on Renewable Energy resources. In this 

model/Project. We focus on the use of renewable energy 

resources. As renewable energy resources are 

environmental friendly because it does not cause any 

harm to the environment and also save the valuable non 

renewable resources. Today is the demand of the use of 

renewable energy resources. We can use alternative energy 

resources in place of non-renewable energy resources 

because non-renewable energy resources are exhaustible 

and cannot be renewed , wind energerefore we should 

focus on renewable energy resources as they are cheap 

sources of energy and most important they are ecofriendly, 

we focus on the use of solar energy, wind energy, 

hydroenergy, Bio Waste Energy etc. it is the demand and 

feature of our generation. We should encourage the use of 

such eco-friendly resources.

SANITATION IN 

OUR RAILWAYS 

2012 

In India the railway is the largest network of transport and 

second in world. Near about 80-86 % of the population is 

using it as a mean of transport for both long and short 

journeys. The rail bogies are almost beset with every 

necessity of life but the waste (excreta, fecal matter or 

urine) is scattered on the railway tracts which is 

unhygienic and fatal for the population in nearby vicinity 

and the passengers on the railway stations, waiting for 

their respective coaches. My project/ model is designed 

with such modalities that it recycles and reutilizes the 

fecal matter along with urine and water to undergo special 

treatment so that it can be converted into water for 

vegetations, biogas for domestic use and even more than 

bio-manure for the agricultural purposes.

BLIND MAN STICK 

Principle: Blind mans stick is based on a single transistor works 

on the principle of switching effect of a transistor. 

Components used: A transistor (141), a 9V battery, an electronic 

Buzzer, a resistor, a stick 

Working : Since this circuit works on the principle of switching 

effect of a transistor which means that when a small current 

passes at the base of the transistor, a large current follows 

through the load at the collector of a transistor. At the base of 

the transistor the two connections 1 & 2 at the base are 

connected with the stick through metal strips at two different 

points one at the bottom tip of the stick and another one joined 

at a height depending upon the water level which is safe for the 

blind man to walk through safely. When a blind man walks with 

this stick in hand and if there is a deep water ahead in his way 

the two connections on the stick will conduct a very small 

current at the base of the transistor which causes a large current 

at the load which is an electronic buzzer which gives alarm at 

this time and cautions him about the depth of the water ahead 

not safe for him to walk through it. In this way this sticks 

protects a blind man from deep water which is a measure threat 

to a blind person. 

Advantages :It has got many advantages provided if it is used 

properly. It will provide him an alarming signal at the time of 

deep circumstantial compulsions. In market related situational 

fields including buses, men and industrial units, he will be 

sensitized by a signal but water being a silent component of the 

universe will not provide him an alarming signal at the time 

when he is going to walk across it so a blind man stick specially 

designed will give him a signal not to cross. 

Limitations : It has got following limitations under which it will 

be properly and judiciously utilized; 

1. First limitation is that it can be used only in water in should 

be limited to water rather than other mediums of universe. 

2. It should be cautiously utilized, because it is an electronic 

device liable to be short circuited at any time.

ROTATING SAND SIEVER 

Manual Sand Siever works on a principle of circulatory 

motion of sieve (Iron Mesh). When the sand is put inside 

the cylindrical iron mesh, the iron mesh (sieve) moves in 

a circulatory motion by hands. The fine particles of sand 

pass through the small holes of sieve and get collected on 

the ground. The bigger particles of sand and pebbles etc. 

do not pass through the iron mesh and remain inside the 

siever and then come out from the exit window. 

Ø This method of sieveing is also used to separate 

similar objects of different sizes, e.g. some cashew 

nuts are smaller in size, whereas some others are 

bigger in size, hence the cashew nuts of different 

sizes can also be separated by this method. 

Ø Similarly, this method can also be used in separating 

husk of walnut seeds. 

Objectives 

2012 

We need fien particles of sand for mixing in cement for 

plastering walls of s house. Fine sand is obtained by the 

method of sieving. And I think that this concept will not 

only save move-power but will also control pollution of 

air. Besides, it will also remove the old traditional method 

where we neeed three or four persons for sieving, whereas 

this model needs only one person for the same. 

The old traditional method is time consuming, while as 

this concept will save time which is an important factor 

for the betterment of every society, including ours. 

Moreover, this model has got the most important 

application in my own village (Mehmoodabad) where 

more than 60% of household depend on this tradition. 


269

JCB 

Scientific principles involved 

Pressure is the force per unit area exerted on a surface divided by 

the area of the surface. 

Pressure = Force/ Surface Area 

Therefore, hydraulic pressure is the force per unit area exerted 

by the fluid on the surface within the container. 

Hydraulics is the science concerned with the water and other 

liquids in motion and their engineering applications. 

Pacal's law is the basic law behind all hydraulic machinery and 

equipment. 

Pascal's law stated that when isan increases in pressure at any 

point in a confined fluid, there is an equal increase at every 

other point in the container. 

Two syringe pump are connected with hose and neck from one 

side of the model of JCB. Each syringe is responsible for the 

moment of hose and neck respectively in up-down direction. 

The other side of each syringe pump is connected through 

rubber tubes with two other syringe pumps placed at the centre 

of the model which act as its control unit. The working is 

governed by simple hydraulics. As the water in the respective 

syringe pump of the control unit is pumped downwards or 

pulled upwards with the help of its piston the hydraulic pressure 

created in the hose and neck syringe pumps make the movement 

happen because of the change in hydraulic pressure., 

Similarly the other side of the model is controlled by the other 

syringe pumps which act in the same manner. 

The left right motion of both the necks is controlled by sort of 

pulley placed at the control unit connected through rope to both 

necks of the model. 

Applications :- Hydraulic pressure finds its applications in 

construction of heavy duty equipments such as bull dozers cater 

pillar earth moving equipment, cranes, equipments used in 

lifting heavy load and metals. 

1. Aircrafts, particularly high speed crafts rely on hydraulic 

systems to operate 

2. Hydraulic systems are widely used in sub marine operations.

CONSERVATION OF GLACIERS 

(ARTIFICIAL GLACIER) 

Material Required: Plaster of Paris, Solar Panel, Motor, 

Battery, Pipe, Electric Wire, Cotton, Water Wheels. 

Scientific Principle : The model works on the technique 

of water conservation at high altitude cold regions. 

Rationale behind the model : As a result of Global 

Warming, the glaciers are melting at alarming rate, thereby 

resulting in depletion of glaciers, leading to scarcity of 

water in near future. The main purpose of the model is to 

preserve water in Harvesting channels where water gets 

preserved and gets freezed during winter. Thereby 

resulting in artificial glaciers. 

Construction of Model : The model consists of a 

mountains range where from the water comes down to the 

traping channels towards the shadow areas of the 

mountain. After going through these channels of shadow 

areas, the water freezes because of extremely low 

temperature during winters. It creates artificial in these 

shadow areas. This technique can be used in Himalayan 

regions which receive high snowfall twice in a year. The 

water in these channels can be harvested b creating 

traping gates and water during spring or summer can be 

released to the adjacent villages through irrigation 

channels for the cultivation of crops in required quantity. 

Water can be lifted by means of water driven wheels by 

means of falling water from the dams. These water wheels 

can also be used as turbines connected with electric 

generators for producing electricity. 

Economic benefits : Increases in Agriculture Production 

Farmers can cultivate two crops in a year. 


271

AGRICULTURE AND 

FOOD SECURITY 

Integrated organic farming is a cyclic zero waste 

procedure in which the waste of one process is utilized as 

nutrient for the other process. 

Here, we have dairy farming, agricultural field, bio gas 

plant, rain water harvesting and bee keeping. The animals 

at dairy farm will get their feed from the field and the 

waste of the animals (cattle dung) will be used as fuel for 

the bio gas plant. The bio gas produced from bio-gas plant 

will be used as commercial fuel for the house for cooking 

and lightening. The waste of biogas plant (Slury) will be 

used as manure for the agriculture field. At the roof of the 

house we have set up a rain harvesting system. After rain, 

the water will be stored in a tank with the help of a 

pipeline connection. This water will be used to irrigate the 

filed. Along with this we have also set up bee keeping. As 

we know that bees are best pollinating agent. So they will 

suck nectar from the flowers grown along the boundary of 

the crop pollination. In this way all of these are 

interlinked with each other and there is no waster at all. 

That is why integrated organic farming organic farming is 

a cyclic zero waste there is no waste at all. And along with 

this our production of crops in the field will be free of 

chemical fertilizers.

Working Principles: a.Water keeps its level 

b.Water in a flood is highly destructive but properly 

chennelised water has multiple uses 

Working of Project: Floods are common all over world, 

India is highly prone to floods which destroy crores of 

wealth in the form of crops, live stock, land, materials etc 

and takes away lot of human lives. For example recent 

Asam Floods 2010 Pakistan (Sindh) Floods. 

Over working project gives an effective and efficient way 

out to flood control and water conservation for useful 

utility thereafter. Flood alert alarms in the model shall 

alert the inhabitants well in time for safe wayout. 

Water of floods can be channelized to barren areas via 

channels, funnels etc were multiple, well interconnected 

chain reservoir systems can be raised purposeful utility 

thereafter. Cost of project shall not be more than a flood 

destroy in one go. Think if we suicide in channelizing 

flood of Ganga River to MP or Rajasthan or Orissa.

SOLAR DRYER FOR 

FRUITS & VEGETABLES 

Material Required: Wooden panels, Glass panes, motor with 

rotors, Exhaust fan, Exhaust vent, Reflector(optional) 

Scientific Principle: The model works on the principle of 

Green house effect. 

Drying is further facilitated by continuous air circulation. 

Rationale behind the model: Kashmiri's used to dry 

vegetables in the open sunlight which deteriorates the quality 

of the vegetable and takes too long. Also some perishable 

fruits can not be dried because of humid conditions. These 

can be effectively dried with the help of Solar drier. 

Construction and working : The model consists of a box 

fitted with glass panes as shown in the figure. 

There is a fan (Agitator) which sets the hot air in to motion. 

There is also an exhaust fan fitted in the enclosed perforated 

box to suck hot air in. The fruit/vegetable to be dried, is put 

in the perforated box in specially designed trays. The hot air 

draws out moisture from the food stuff and thus it gets dried 

quickly. 

Usually, it takes about 36 hours to dry the vegetables 

completely. 

This model can be used on large scale with slight 

modifications/ improvisation. 

Importance of Soar drier : Solar dryers used in agriculture 

for food and crop drying , for industrial drying process, 

dryers can be proved to be most useful device from energy 

conservation point of view. It not only save energy but also 

save lot of time, occupying less area, improves quality of the 

product, make the process more efficient and protects 

environment also. Solar dryers circumvent some of the major 

disadvantages of classical drying. Solar drying can be used 

for the entire drying process or for supplementing artificial 

drying systems, thus reducing the total amount of fuel energy 

required.

DOMESTIC HYDROELECTRICITY 

Concept Behind the model 

The model under the name domestic Hydroelectricity can 

be used in High Rise Buildings, Multi Storey Hotels/Malls 

and other Buildings. The energy can be tapped using 

already stored water in water tanks at roof tops of high 

buildings. The water used for daily consumption in Hotel 

rooms, Laundries. 

Rationale behind the Model 

2012 

In this model, an electric motor has been used to lift the 

water and falling water is allowed to fall on turbine linked 

with dynamo to produce electricity by electro-magnetic 

induction. Then electricity is shown to run various loads. 

The instant electricity so produced can be used to heat 

water, can be used in laundries, to light up parking lights 

& various other petty works. Also lights installed for 

beautifying the garden can run on instant electricity so 

produced. 

The electricity so generated will save extra energy which 

would have been used in absence of it. 

The principle behind the model is Electromagnetic 

induction. The potential energy acquired by raised water 

converted to kinetic energy of falling water is converted 

into electrical energy by the dynamos by electromagnetic 

induction. 

Though initial cost of this project applied in the high rise 

buildings to tap energy from the raised up stored water 

may be high but its running cost will be cheaper on one 

hand and eco-friendly on the other.

RAIN WATER HARVESTING 

IS CONSERVATION OF WATER 

Main Objectives of Rain Water Harvesting is conservation of 

Water 

—Conserving water helps in minimizing the effects of water 

shortage and helps build a better defence against future 

drought years. 

—If we save water now, we are helping to ensure a water 

supply adequate for future generations. 

—Saving water saves money. Saving water now means having 

water available in the future for recreational purposes, too. 

—We need to think of future generations, people will not have 

a sufficient supply of water unless we become more 

concerned with how we use our water today. 

—WATER WATER EVERYWHERE, NOT A DROP TO 

DRINK. 

RAINWATER HARVESTING is one of the main methods of 

water conservation. The main steps involved in the process 

of rainwater harvesting are: 

—Catchment- Any surface can act as a catchment for 

rainwater harvesting. Roof tops are favoured because of the 

large amount of run-off generated from them. Moreover there 

is relatively less likelihood of contamination. 

—Conveyance- For rooftop rainwater harvesting gutters and 

rainwater down pipes are conveyance systems. They should 

be designed so as not to lose any water during conveyance 

process. 

—Storage- From the simplest ground level tank, to 

underground sumps on surface lined ponds are options for 

rainwater storage. From the storage device water can be 

pumped and used.

CYCLE WATER-PUMP 

Working Principle 

A water-Pump pull/push water only when rotated above 

2000 rpm (rotation per minute). Without using any 

electric motor or fuel engine, it is achieved by connecting 

the water-pump to a cycle wheel which has relatively 

large circumference than the pulley of water-pump. One 

rotation of the paddle can make the water-pump to rotate 

over thirty times, thus at moderate paddling rate, about 

3000 rpm can be achieved in this model. 

Construction 

The science model was constructed at our school under 

the guidance of Dr Purshotam Singh by using a waste 

cycle and a water-pump. The rear wheel of the cycle, 

which is connected to the paddle through a chain, is 

connected to the water-pump pulley by a string. 

Importance 

2012 

The Cycle Water-Pump can be used to pull and supply 

water to short distance e.g., to pull water from well, to lift 

water into water-tank on roof, for small scale irrigational 

purposes. By using this model we can save electricity and 

fossil fuel. It is environmental friendly as does not cause 

any kind of pollution. It is particularly useful in those 

areas where electricity is not available. 


277

SOLAR REMOTE DOOR 

Principle: It is based on the principle that when current is 

placed in an external magnetic field it experiences a 

torque which rotates the armature coil which in turn 

makes the door slide. 

Construction: The main parts of solar door are: 

1. Solar Panel, 2. Battery, 3. DC Moter, 4. Pully, 

5. Remote system, 6. Channel, 7. Switch, 8. Indicator, 

9. Doors 

Working: Solar panel which converts solar energy into 

electrical energy, this electrical energy is used for charging 

6V battery. This 6V battery maintains potential difference 

across the circuit containing different parts. thus a current 

flows i the circuit by using battery which ca rotate the 

armature coil. The pulley fixed with shaft also rotate with 

the rotation of armature which in turn rotates the belt and 

other two pulleys. On pressing the remote soft key the IR 

receiver receives the signal thus closes the circuit and 

makes the armature coil to rotate one direction which in 

turn slide the door to one side. This can be seen by 

glowing the yellow indication on pressing the another soft 

key it reverses the direction of current and then reverses 

the direction of rotation of armature coil which in turn 

can slide the door opposite direction. this can be seen 

again by the glowliness of yellow indicator. 

Thus the property of DC motor to rotate a clock wise 

direction ad counter clock wise direction is utilized here 

to make door open and close,

ELECTROMAGNETIC INDUCTION 

Materials Used: 

1. Acurret source (Operating radio set), 2. Two conductors ( 

P-coil and S-Coil), 3. A detector (Loud Speaker or head 

phone) 

Construction: To demonstrate electromagnetic induction 

that is transfer of current from one conductor to another 

conductor without their actual physical contact. A Primary 

coil consisting of large number of insulated loop turns ofr 

copper should be connected in series with a operating radio 

set in place of its actual loud speaker. A secondary coil also 

connected in series with a loud speaker should be placed 

away without any actual physical contact with the primary 

coil. 

On switching “O” the radio set, its broadcast is heard on the 

loud speaker or head phone which is isolated from the radio 

set. The intensity of broadcast can be varied by keeping the 

loud speaker with its secondary coil at different orientations 

and changing the medium between the P-Coil and S-Coil. 

Applications: 

1. The Principle of electromagnetic induction is involved in 

dynamo or electric generator. 

2. In electric transfer 

3. In micro phone 

4. In induction heater 

5. In wireless communication 

2012 

Moreover electromagnetic induction can be used to test the 

magnetic permeability of a medium.

ECO SOLAR WATER HEATER 

Principles: The project is based on four basic principles 

i. Absorption of heat energy by black bodies. 

ii. Green House Effect created by transparent plastic. 

iii. Increased surface area of absorption by coiled water 

pipes. 

iv. Thermo siphon i.e. hot liquid comes on the upper 

layers due to decrease in density of water on heating. 

Materials Required: Wooden panel, waste plastic bottles 

(1 1 / 2 litres), a black coloured flexible water pipe, a tap, 

water reservoir (tank) and few light reflecting sheet. 

Procedure/summary: The chief property of this project is 

that it makes use of disposable material and thus becomes 

an eco-friendly assignment. Since these materials are nonbiodegradable, 

they create enormous problems to our 

environment particularly polluting our soil. Making use of 

such material will prevent soil and water pollution to a 

good extent. 

In this project water is made to flow through an input 

pipe connected to an elevated tank on one end and a 

panel made up of series of black pipes coiled within 

disposable water bottles. On the other side of the panel, 

the pipes are again joined to a common pipe that acts as 

an output. The input pipe is connected through the lower 

side of the panel while the output pipe is attached via the 

upper side of the panel. 

The circulation of water in this project does not require 

any motor device but takes place due to thermosiphoning. 

The difference in densities of hot and cold 

water separates the two and hot water is easily drawn 

through the output pipe as the later is coming out through 

through the upper end of the panel.

PLASTIC AS A SOURCE 

OF FUTURE ENERGY 

RESOURCE 

2012 

The present project submitted and demonstrated by Suraj 

Oraon envisages the conversion of plastics and polythenes 

into their components which can be re-used. 

In the present project the conversion of plastics and 

polythenes has been proposed by the process of pyrolysis. 

The devices used are conventional but the concept of 

deriving useful components from a non fuel based source 

has been put foward as an innovative idea. The project 

model exhibited indicates that the process although 

simple will not be cost effective. But keeping in mind the 

nuisance of plastics and polythenes, a human generated 

monster, has to be disposed off by all means.

A project for management of disaster has been put forward 

by Gulfasha Parvin. 

Jharkhand or for that point a large area of India is under 

the naxalite terror. The most common area where the 

attack by the naxalites occurs, is the railways. 

It is very difficult to monitor the entire rail track for any 

disaster. 

In the present model, although the cost is point of 

concern, a simple device would intimate the railway 

authorities whether a particular section of the rail track is 

utilizable or not.

WASTE MANAGEMENT 

PLANT 

2012 

There are two projects presented by Shashank Gupta. 

The first project involves the solvent extraction of color 

and essence from flowers. The methods used are 

conventional and simple. The cost effectiveness of the 

process has to be taken into account. 

In the second project, a proposal has been given for the 

reutilization of plastic and polythene wastes which is 

scourge now a day. The creation of plastics has of course 

made life simpler but being non biodegradable removal of 

these has become a source of concern throughout the 

world. 

In this project Sri Shashank Gupta, has proposed 

degradation of the plastics and polythene using Pyrolysis 

as a method to get the components of the plastic in other 

useful forms. 


285

ACIDIC SOIL AND 

BIOCHAR ITS RESCUE 

Absorption of plant nutrients by the soil is pH dependent. 

In the present project survey indicates that the soil of 

Jharkhand is more acidic than what is required for proper 

absorption of nutrients. 

Ankita Sarkar in her project has proposed the utilization 

of waste obtained from agriculture and poultry farms to 

change the pH of the soil of Jharkhand from more acidic to 

the required level for proper utilization of the nutrients. 

Pyrolysis technique has been used to generate BIOCHAR 

from the agricultural and poultry wastes, which when 

mixed with the soil will facilitate the required pH of the 

soil.

FOLDING VEHICLES 

2012 

The population of the world is increasing day by day. 

Corollary to this the amenities being used by the persons 

are also increasing. The most common amenity used is the 

mode of transport. Every family has more than one 

vehicle, parking of these vehicles on the road creates a 

traffic problem. 

In the present project submitted by Chinmaya Maharana a 

model of folding car has been proposed. The device is 

simple and will contribute to the solution of jams. The 

folding car proposed is simplistic in nature and can lead 

to utilization of not only minimum space but will also 

make the vehicle stored as per the space available. The 

technology of folding cars must be pursued by the 

manufacturers aggressively and will be a good solution for 

space utilization. 

The device used is cost effective. The device needs to be 

perfected for actual use. The concept is innovative and 

appreciable. 


287

An original idea of inter conversion of energy has been 

proposed by Ayush Kumar. The basic theme of the model 

was generation of electricity by converting the kinetic 

energy due to the motion of vehicles on the road. 

Ayush Kumar has proposed the extra utilization of speed 

barrier with a simple device to generate electrical energy. 

The project has to be refined taking into consideration the 

volume of traffic on the road on which the device is to 

installed so as to get a continuity of motion of the speed 

barrier.

PRINTING MACHINE 

2012 

Saif Ali Khan has used very simple devices to make a 

printing press which can compensate the xerox machines. 

In villages where it is very difficult to make of the 

documents the device proposed by Saif Ali Khan will be 

highly appreciated. 

The working model is simple in approach and does not 

need complicated machinery. 

The project is practical and will be highly useful both in 

villages and urban places where availability if electricity 

is limited.

SMALL WATER PUMPING MACHINE 

IN THE AGRICULTURAL SECTOR FOR 

IRRIGATION BY MOBILE CONTROL 

In the present scenario, mobile has become a common 

instrument in the hands of one and all. Transmission of 

radio waves from these mobiles can be used to monitor a 

large number of devices from a far distance. 

A very innovative device which can be used without large 

requirements has been proposed by Sujeet Kumar Singh. 

The idea of a control of start and closure of water 

pumping without being physically present at the site is 

the rationale in this present project. 

The project has been devised in a very clean fashion and 

appears to be useful in its simplicity.

In the present days electricity is main source of energy for 

different processes which are carried out in the industry 

as well as in agriculture. Water for agriculture has to be 

pumped out using electricity which utilizes bio fuels the 

abundance of which is decreasing day by day. 

In the present project submitted by Shiba Ram innovative 

idea of using custom designed speed breakers to pump 

water for different processes used in agriculture from bore 

wells when electricity is not available has been proposed.

this process but it is not so efficient for such places where 

the wind speed is low. 

I have tried to place a new device which can work even at 

places with low wind velocities using the concept of 

magnetic levitation of the fins for wind energy. The device 

proposed will reduce the friction loss and will be cost

SUBSTITUTE OF GEOTHERMAL 

ENERGY TO GENERATE ELECTRICITY 

FROM BURNING COAL MINES 

The present project submitted and demonstrated by me 

envisages the conversion of heat energy to electrical 

energy. 

In the present project the fire in the Jharia coal mines can 

be used to generate electricity by using an ingenious 

project of passing water into the fire and converting it to 

steam. In turn the steam generated will be passed through 

turbines which will be used to generate the electricity. 

A special reference to his project is the use of special 

turbine which can rotate even at low pressure of the 

steam. 

Another thing worth mentioning here is recycling of the 

steam of the turbine by using condenser and putting it 

back into the fire for conversion to steam.

PETROL AND DIESEL 

SUBSIDY OPTIMISATION 

Introduction and Objective: 

Presently, all the vehicles get subsidized diesel irrespective of their 

efficiency and affordability. Though petrol subsidy is withdrawn but 

it is still sold at lower price due to public pressure. This causes 

heavy burden on the government and tax-payers. High-end vehicles 

and effluent class doesn't need any subsidy on fuel, rather they 

should be paying extra price for luxury. 

Benefits to society: 

2012 

1. There will be less burden on government due to lower subsidiy. 

2. The extra price earned from high end vehicles will further 

reduce this monetory burden. 

3. Money saved on subsidy can be used for social programs like 

education, healthcare etc. 

4. Low fuel prices for goods carrier will reduce the cost of essential 

goods like vegetables, pulses, milk, etc. thereby reducing the 

inflation. 

Recommended solution and operation method (Working model is 

displayed): 

1. Decide different rates of fuel for different type of vehicles. For 

example Rs 40/- per litre for small cars and public transport, Rs 

70/- per litres for mid size cars etc. 

2. Fix RFID (Radio frequency identification device) tags on every 

vehicle that will contain information about type of vehicle and 

rate of fuel to be charged. 

3. Install RFID tag reader on every petrol pump. As soon as the 

vehicle enters the petrol pump, the reader will read the RFID tag 

of the vehicle and charge the fuel rates accordingly. 

4. Government will need spend some amount on server and IT 

infrastructure but that will be insignificant as compared to its 

benefits. 

Cost of implementation of project in real life: 

1. Every vehicle owner will spend only Rs 50/- for RFID tag which 

is very affordable. 

2. Petrol bunk owners will spend only Rs 2500/= on RFID tag 

reader. 

3. Government will need to spend some amount on IT 

infrastructure which will be insignificant as compared to the 

benefits of this project.

in the west before advent of cane and beet sugar. Rearing 

of honey bees on a commercial scale is called apiculture. 

Main advantages of the project:- 

—It is used in the manufacture of medicines 

—It reliefs sore throat, cough and cold. 

—It improves the economic status 

—It is used as colouring and flavouring materials 

Importance of the project:- 

—To understand the importance and uses of honey, bees

FLYING SAUCERS 

2012 

Introduction: A flying saucer (also referred to as a flying 

disc) is a type of described flying craft with a disc or saucershaped 

body, though has also been used generically to refer 

to any reported anomalous flying object of any shape. The 

term dates from 1947 and was later supplanted by the 

USAF in 1952 with the even more-generic unidentified 

flying objects or (UFO's). These are usually described as 

silver or metallic, sometimes reported as covered with 

running lights or surrounded with a glowing light, hovering 

or moving rapidly, either alone or in tight formations with 

other similar craft, and exhibiting high maneuverability. 

Explanations:- In addition to the extraterrestrial hypothesis, 

a variety of possible explanations for flying saucers have 

been put forward. One of the most common states that most 

photos of saucers were hoaxes; cylindrical metal objects 

such as pie tins, hubcaps and dustbin lids were easy to 

obtain, and the poor focus seen in UFO images makes the 

true scale of the object difficult to ascertain. However, some 

photos and movies were deemed authentic after intensive 

study. An example was the saucer-like object photographed 

by farmer Paul Trent near Portland, Oregon in 1950, which 

passed all tests when studied by the Condon in the 1960s. 

Another theory states that most are natural phenomena 

such as lenticular clouds and balloons, which appear disclike 

in some lighting conditions.Also put forward is the 

theory that they may be an as yet undiscovered form of life 

that inhabits the high atmosphere. 

A third theory puts all saucer sightings down to a form of 

mass hysteria. Arnold described the craft he saw as saucerlike 

but not perfectly round(he described them as thin, flat, 

rounded in front but chopped in back and coming to a 

point),but the image the circular saucer was fixed in the 

public consciousness.

PRODUCTION OF PAPER BY 

USING BANANA STEM 

How can we make banana peelings into paper? 

Materials required: 

Banana stem 4 pieces, Ca (OH) 2, water 2 ltrs, 1- knife, 

bucket, etc.., 

Take about ½ kg of banana stem pieces and add 200 ml of 

Ca(OH)2 solution. Grind it by using a mixcy after 

grinding we will get a paste, then pour the paste into a 

bucket which is containing one inch of water then stirr 

the paste till the particles are equally distributed in the 

water. Take a flour jallery and immerse it the mixture and 

lift it then the particles are collected on the jallery, dry it 

in sun light after drying we get the paper. 

How the paper is formed? 

The banana stem is made up of cellulose but it also 

contains acids like murasic acid and mosaic acid etc…, Ca 

(OH) 2 is a base acid and base reacts with each other to 

form the product of paper. 

Applications 

1. New jobs are created. 

2. It is eco-friendly. 

2012 

3. It controls the environment pollution. 

4. It minimizes the raw materials required to 

manufacture the paper.

AEROPONICS 


* The main advantage of Aeroponics is Conservation of water 

energy . 

* It increases air exposure . 

* It benefits oxygen in the root zone . 

* It supplies oxygen which is an excellent purifier for plants 

and the Aeroponics environment . 


* Aeroponiclly Grown food 

* Aeroponics for space and Earth 

* Benefits of Aeroponics for earth and space 

Aeroponiclly Grown food:- 

In 1986 stoner was the first person to 

market fresh Aeroponiclly grown food to a national grocery 

chain . 

Aeroponics for space and Earth:- 

Aeroponics with its use of a hydro-atomized spray to deliver 

nutrients, minimize water use, increases oxygenation of roots 

and offers excellent plant growth, white at the same time 

approaching or bettering the low nutrient solution through put 

of other systems developed to operate in low gravity. These 

many advantages combined with the results of his research 

that prove the viability of Aeroponics in microgravity makes 

Aeroponics a logical choice for efficient food production in 

space . 

Benefits of Aeroponics for earth and space:- 

Plants grown using Aeroponics spend 99-98% of their time in 

air and 0.02% in direct contact with hydro-atomized nutrient 

solution the time spent without water allows the roots to 

capture oxygen more efficiently .

the control of railway gates. As a train approaches the 

railway crossing from either side, the sensors placed at a 

certain distance from the gate detects the approaching 

train and accordingly controls the operation of the gate. 

Also an indicator light has been provided to alert the 

motorists about the approaching train. 

Track Switching:- 

2012 

Considering a situation wherein an express train and a 

local train are travelling in opposite directions on the 

same track: the express train is allowed to travel on the 

same track and the local train has to switch on to the other 

track. Indicator lights have been provided to avoid 

collisions. Here the switching operation is performed 

using a stepper motor.

HARNESSING ENERGY 

FROM REVOLVING DOORS 

Our biggest problem is 'power crisis' and the challenge is 

to harness power from various sources around us. 

Revolving doors can be seen rotating almost all the time in 

busy places. Why not convert the 'Rotational energy' of 

these doors into 'Electrical energy'? 

If the central bearing of the revolving door is connected to 

wheels and the wheels to a motor, as the door revolves, 

the wheels rotate and the motor produces energy which 

can be supplied to the bulbs. Wheels are progressively 

reduced in size using gear system, i.e., when the bigger 

wheel rotates once, the second wheel rotates 12 times; 

when the second completes one rotation, the motor 

(dynamo) rotates 40 times approximately resulting in 480 

rotations. 

An improved version can help in storing the energy thus 

produced ensuring uninterrupted supply of power even 

when the doors don't rotate. 

This mechanism is applicable in airports and elsewhere: 

if the detectors are fixed to the revolving doors, the energy 

thus produced can be supplied to the detectors too. 

It was observed that on an average, the door of a 24X7 

hotel opens around 20,160 times per day. As the dynamo 

produces 2 watts of power for 1 rotation, the dynamo 

would harness 38,764 watts of power! 

A small step, a big gain.

HYDRAULIC ROBOT 

Introduction: Hydraulics is the technology where 

pressurized fluid is used to do useful work. It includes 

generation, controlling and transmission of pressurized 

working fluid. Fluid includes both liquids and air or gases. 

If liquid is used as working fluid, the system is Hydraulic 

system. If air is used as working medium, the system is 

Pneumatic system. The present work uses hydraulic 

system to imitate human hand motions and can be used to 

transfer material from one place to another. 

It works on the principle of Pascal law, which states 

“Pressure applied to a confined fluid is transmitted 

undiminished, throughout the system and acts 

perpendicular to the surfaces in contact with fluid”. 

Main advantages of this fluid power project:- 

• Limited only by physical strength of material 

• Ease and accuracy – lever operated 

• Multiplication of force is easy 

• Fewer moving parts 

• Compact and simple, well suited for automation 

application 

• Automatic protection against overload 


The fluid is controlled directly or automatically by control 

valves and distributed to various hydraulic motors and 

hydraulic cylinders through hoses and tubes. In present 

project we make use of syringes, wooden arm, 

incompressible fluid, tubes and screws. 

This hydraulic system find its application 

in various fields like elevators, RKM engine, tail lifts, 

aerial work platform, land tamer, chairlifts, fork lift trucks.

A WAY TO MINIMISE 

CARBON DIOXIDE EMISSION 

FROM INDUSTRIES 

Introduction: Industries emit large amount of smoke which 

mainly contains Carbon dioxide. Increase in Carbon dioxide 

content in the atmosphere is an alarming issue as it causes global 

warming. In future, Global warming may become a threat to the 

existence of life on earth. Because of global warming, ice melts 

in polar region and there is significant rise in sea level and few 

islands may get submerged in sea. This project is applied to 

control the Carbon dioxide emission from industries. 


— Both air pollution and global warming are controlled. 

— This project can also be implemented in other areas like 

automobile exhaust system, thermal power generating 

station, railways etc. 

— The end product calcium carbonate is used as raw material 

in the manufacture of cement, fertilizer etc. 

Project:- 

Industries emit large amount of smoke which mainly contains 

unburnt carbon particles and carbon dioxide gas causing air 

pollution and global warming. The chemical properties of carbon 

dioxide can be taken as an advantage to minimize its emission. 

Here is a way to minimize its emission. 

In chimney, the smoke is made to pass through a chamber 

containing a mist of lime water. Unburnt carbon particles get wet 

and settled down. The carbon dioxide gas gets absorbed by lime 

water to form calcium carbonate according to the following 

equation: 

Ca(OH) + CO ¾¾® CaCO + H O 

2 2 3 2 

2012 

Thus CO emission is minimized. Hence air pollution and global 

2 

warming are controlled.

A WAY TO MINIMISE CARBON 

DIOXIDE EMISSION FROM 

INDUSTRIES 

Introduction and Objective:- The project aims at 

developing a highly cost effective microcontroller based 

toilet monitoring system for trains. The idea behind this 

project is to help the track cleaners in the stations. The 

outlet unit of the toilets is controlled and monitored with 

the help of vibration sensors and microcontroller. 

Vibration Sensor Micro controller Amplifier 

Block diagram: 

Vibration Sensor à Amplifier à Micro controller 

Technical Details:- The underlying principle is 

phenomenon of conversion of mechanical vibration into 

electrical variations. Electrical pulses are undergone 

amplification by transistor amplification stage. 

The electrical pulses are generated only when there is 

vibration and these vibrations are converted to electrical 

pulses (i.e. when train is under motion) with some delay 

the outlet unit of toilet is made open (so train moves out of 

station and we can keep the track and platform clean.) 

When there is no vibration the electrical signals are not 

present and the outlet unit of the toilet is made close(i.e. 

when train is at station platform). 

These signals are amplified and given to the 

microcontroller to make the outlet unit open/close and we 

can adjust the time delay. 

Materials Used:- Vibration Sensor, Transistors, Ossilators, 

Microprocessors, Small L.C.D.

GENERATION OF ELECTRICITY 

BY SMOKE RELEASED BY 

THE VEHICLES 

Introduction: Today the demand for the electricity is more 

than the supply, because lake of rainfall . In Raichur and 

Kudithini thermal power station are facing the scarcity of 

coal. Now a days human life is fully dependent on 

electricity. During last decade the cost of 1 unit of electric 

power is Rs.1.12 only. Today the cost is Rs. 3.76 later in 

the year 2020 it may be raises to approximate Rs.20 per 

unit. At present we are thinking alternate method to 

generate electricity. 

Model work and its advantages of the project : Our 

model is based on special concept of generating electricity 

from vehicles. In all vehicles after combustion of fuel 

waste smoke released. Released waste smoke is very 

power full, turns the turbine fixed at the silencer pipe and 

thus generates energy. 

Working : Petrol and air mixes in proper proportion in 

carburetor .After that fuel & air enters in to the engine, 

next combustion will takes place with the help of spark 

plug. Piston moves and heat energy is converted into 

mechanical energy. 

After combustion of the petrol in engine, waste smoke 

exhaust throw silencer pipe. Waste smoke is very power 

full and rotates the turbine. Two computer exhaust (ie, DC 

motors ) fans are fixed in front of silencer pipe and they 

act as turbines. Exhausted smoke rotates the fans and 

generate the electricity. 

Generated electricity is stored in the battery, further it is 

used for the domestic purpose. Stored electrical energy is 

converted into other forms of energy and used in our 

home

RAIN WATER HARVESTING + GREY 

WATER TREATMENT+ GROUND 

WATER RECHARGE 

Introduction : Rain Water Harvesting + Grey Water 

Treatment + Ground Water Recharge brings general 

awareness among people in enhancing their knowledge 

and skill on the importance of natural resource 

conservation. It is easy to adopt for houses and local 

institutions. 

Importance of the project : 

—Collection and use of roof water. 

—Grey Water Treatment. 

—Increasing Ground Water Level. 

Collection and use of roof water 

Only less than 1% water is supporting the organisms. The 

demand for water is increasing as increasing population. 

In this method we can make use of each and every drop of 

rain water. It is one of the method to conserve water. 

Grey Water Treatment : 

Grey water is waste water generated from domestic 

activities such as laundry, dish washing, bathing, hand 

wash water etc., Can be treated and reused for the 

secondary purposes. This system helps in recycling & 

reuse of waste water. 

Increasing ground water level 

Excess rain water enter into the ground and increases the 

ground water table. Through tubewells we can make use 

of ground water.

DREAM VILLAGE OF 

AKASH.K.R 

Introduction: 

A Dream Village of AKASH.K.R is composed of using 

renewable natural resources such as Bio-Gas, Wind 

Energy, Solar Energy for lighting, to run vehicles, for 

cooking, pumping of water without electricity and 

conserving water by following the methods such as Rain 

Water Harvesting and Drip Irrigation which makes us to be 

self dependent. 

It is a self dependent village:- 

The energy required for the villagers will be generated by 

themselves by using renewable natural sources such as 

Bio-Gas, Wind Energy, Solar Energy which can be used for 

cooking, to run vehicles, to generate electricity and even 

to pump the water etc… and make the villagers self 

dependent and not on the power which is supplied by the 

government. 

Avoids environmental pollution:- 

2012 

By using the above mentioned renewable natural sources 

and using bio-degradable waste to generate bio-gas. The 

poisonous gases such as CO, CO2 etc...Will be get 

controlled and even the metro cities can adopt biodegradable 

waste management and can reduce the risk of 

throwing of bio-waste on road side and keeps the city 

clean and green. Or else definitely a day will come the 

people have to go in search of oxygen booths or carry 

oxygen cylinder on their back to breath. We have to 

welcome the new born baby to the earth by using oxygen 

masks.

SOLAR STOVE (FURNACE) 

Introduction: The purpose of this paper is to summarize the basic 

principles that are used in the design of solar stove. Now-a-days Solar 

Energy is used in varies Solar Equipment's. Among Them Solar Cooker is 

rarely used in our society. But it is a closed box and cannot be used as 

open Furnace. we created a solar stove (Furnace) that is our innovative 

idea .By which we can cook and bake any food items like Roti, Dosa, 

Rice, meat, chicken, fish etc. in open vessels and mix up with spoon as 

and when. 


—Solar Household Energy (SHE) strives to unleash the potential of solar 

cooking to improve social, economic and environmental conditions in 

sun-rich areas around the world. 

—Over half the world's population currently relies on wood, charcoal or 

other biomass for daily cooking, leading to respiratory diseases, 

economic hardship, environmental degradation, and carbon emissions. 

—in order to reduce the use of wood and charcoal for cooking fires that 

has seriously damaged the forest cover 


In this Toll system sensor is operated by the heavy and light motor 

vehicles. When ATM card is inserted in the toll booth at particular place 

automatically cash will be withdrawn from account of the vehicle owner. 

For heavy motor vehicles Rs 10 is deducted and for Light motor vehicles 

Rs 05 is deducted. 

Automatic dig formation due to non payment of the toll gate fees:- 

In this mechanism if the driver fails to insert the ATM card and crosses 

the toll automatic dig formation takes place. This information goes to the 

security office by siren mechanism. 

Traffic controller unit. (space saver):- 

In a space saver or traffic controlling action circular rotating system is 

used. By the button operation the vehicle will be brought to the ground 

level from the rotating system. It is also suitable for metro cities where 

space is less. 

Electricity Generation:- 

The electricity can be generated beyond the toll by moving the vehicles 

on the roller mechanism. The shaft will rotate under the road. This shaft 

rotates the dynamo. It generates the electricity. The generated electricity 

is stored in the battery and it is utilized.

ECO FRIENDLY HOME 

Introduction : 

2012 

Man is very much different from the animals because of 

his thinking power and wisdom. But now -a- days, 

because of his wisdom and over utilization of technology 

and science our Environment has been polluting in a 

major hike. Because of this Environmental pollution, we 

are facing hazardous problems such as Global warming, 

problem of Garbage disposal; Water problem (Scarcity) Air 

pollution etc. Hence we need to attend these problems 

from the ground level and must do something to avoid 

further pollutions. Therefore the need of the hour is that 

we act immediately in addressing these issues from our 

houses.

TROLLEY TO CHANGE DESIGN 

CARDS IN COTTAGE PICK N 

PICK POWER LOOM 

Introduction: When a punched card punches the 

jacquard hooks, body design and pallu design in a saree is 

formed. For the required design, cards should be changed 

at the time of production. Depending upon the size of the 

design, the number of cards per design may be from 300 to 

3000 or more, where each tagged card weighs 50 – 60 

grams with the thread and the supporting rod. 

These cards should be hanged at the height of 8 feet to 10 

feet above ground, for medium or big design (3000 cards 

weighs around 150kg) where 3 labours are required and 

the time wasted is about 40-50 minutes to change the 

cards once. Per saree cards should be changed twice. 

Aim: This project aims to structure a trolley to save man 

power, time and to increase production in cottage pick n 

pick power loom, while changing the design punched 

cards to jacquard. 

After fitting the trolley : Time spent for changing cards per 

loom was decreased from 10-13 hours to 55-60 minutes 

per week Production per week from 1 loom was increased 

from 7-8 sarees to 11-12 sarees. A labour alone can change 

cards without any help. There is no chance for any 

obstacles because the trolley is fitted and a labour needs 

just a push and pull. The life span of the punched cards 

can be increased due to not using it manually. Cards will 

not spill because they are hanged and no manual activity 

made. With a push and pull labours need not rest after 

changing the design punched cards.

SECURITY MEASURES 

IN PUBLIC PLACES 

Introduction: With crime rates up in India, many 

residents feel uneasy about relying solely on the 

protection of the law. With continued technological 

advancement, there is no reason not to look into 

additional security. A home security system (Burglar 

alarm) is a great way to provide extra protection for your 

home or business. 


—It reduces man power 

—It saves time, money 

—It provides security and accuracy 

—It avoids robbery and thefts 

Importance of project 

—IR rays and laser rays used in this project are invisible 

for robbers. 

—It can be used in place of security persons. 

—We can know the entry of robbers when we are not 

present in that place.

MOBILE CONTROLLED 

ROBOT Li2-MOBILE 

ROBO (USING DTMF) 

2012 

Stepper motor is found in a lot of applications such as 

computer peripherals, business machines, process control, 

machine tools and robotics. Especially in different areas of 

robotics, process control like silicon processing, I.C. 

Bonding and Laser trimming applications, it is necessary 

to control the stepper motor from remote places. The 

present paper describes a remote angular position control 

system of stepper motor using DTMF (Dual-Tone Multi- 

Frequency) Technology as an alternative means of 

communication using Radio Frequency (RF) with 

advantages of simplicity and audibility. DTMF Technology 

has been used here to implement acoustic communication 

for controlling the angular position of the stepper motor 

remotely anywhere in the world through mobile phone 

network. The desired value of angular position signals, in 

terms of DTMF tones have been generated by using a 

mobile phone. The microcontroller has been used to 

implement the control algorithm after receiving the DTMF 

tone. Since no extra transmitting and receiving device is 

needed except mobile phone, the system is very much 

simple, rugged, and cost effective. The experimental 

results indicate that the system has high resolution, 

repeatability and error is also within tolerable limit. 

Keywords: DTMF Technology, Position Control, Stepper 

Motor, Acoustic Communication, Remote Control, Mobile 

Phone.

WASTE WATER RECLAMATION 

AND REUSE 

We all know that water is one of the most precious and 

important natural resource in this world. It is very 

essential for almost all the dimensions of life. We use 

water for both potable and non-potable purposes. But 

nowadays, the usage of the water sources has been 

increasing gradually because of the rapid growth of 

population, industrialization and urbanization. Water is 

an inexhaustible resource, but 96.5% of water from the 

water bodies is saline. Therefore, there is a scarcity for the 

supply of the fresh water. 

The solution to this problem can be found out by 

adopting the process of “waste water reclamation and 

reuse.” This method can be used by various factories, 

industries and other big organizations in which they can 

use the treated water for many non-potable uses. Waste 

water reclamation and reuse is nothing but recycling of 

the waste water and reusing it for many non-potable 

purposes. Approaching this process mainly conserves the 

fresh water sources along with associated cost saving. If 

we adopt this process, our city will be “greener, cleaner 

and hygienic with less waste water…”.

WATER AS A FUEL 

Introduction: It is impossible to live without energy in 

modern times . Man has obtained energy from natural 

sources like wood,coal and petroleum from the ancient 

times. But these sources are likely to disappear very soon . 

We have to find an alternative solution to solve this 

problem.So purpose of our project is to reduce energy 

crisis by using water as a fuel. 


— It reduces energy crisis 

— It increases the efficiency of the vehicles 

— It reduces the pollution 

— It is cheaper and three times more efficient than petrol 

— It is renewable source of energy 

Importance of the project 

— We are using water as a fuel which is abundant on the 

earth 

— This process is very simple 

— From hydrogen we can produce electricity & water 

using fuel cell 

— Fuel cell is very useful in space vehicles 

Working of the model Electricity is produced using solar 

panel & wind mill.This electricity is used to electrolyse 

the water Hydrogen 

Produced during this process is stored in a cylinder . This 

hydrogen is used for various purposes. 

— In factories to synthesis Ammonia 

— In fuel cells to produce electricity & water 

— As a fuel to run vehicles.

world. The circuits have one best thing that avoids the huge human 

power and takes us in scientific development. 


—Socially Useful. Less expensive. Avoids accidents. Reduce labour. 

Prevents Drink and Drive. 

Importance of the project:- · Automatic RAILWAY GATE 

OPEN/CLOSE operation. Without human power it will work.(There 

is no manual work). Traffic controller. Avoids accidents. No DRINK 

& DRIVE cases. Controls alcohol consumption. 

Automatic Electronic Circuits Operations:- In AUTOMATIC 

RAILWAY GATE circuit Transmitter is connected to the train and 

receivers are connected to the railway track. When transmitter and 

receiver1 touches each other, it will generate a signals and sends to 

micro-processor. Micro-processor sends the signals to the motor. 

Motor is connected in the railway gate. By the signals automatically 

the railway gate closes. After the train passes from the gate in same 

distance there will be another receiver when receiver2 and 

transmitter touches each other it again generates a signal and sends 

it to micro-processor. Micro-processor sends a signal to motor in the 

gate and hence the gate opens. 

In LIQUOR DETECTOR CIRCUIT, SMELL DETECTOR is connected 

in a vehicle in front of the driver. If the driver is drunk, because of 

the smell of alcohol the detector circuit will send the signal to the 

relay. Relay automatically switches off and the vehicle engine turns 

off. By 

using this type of technology we can prevent the drunk & drive cases 

i.e, accidents. 

When train reaches receiver, the transmitter and receiver 

compresses and digital signal produces in microcontroller. When 

signal reaches IC-NE556 it processes and transfers to motor 

processing circuit. Signal process continues like ON/OFF mode, as 

timer circuit. In liquor detector also same timer circuit works with 

the help of IC-NE555 which detects smell and relay controller 

processes. Also two types of digital signals produces like ON/OFF 

signals.

Introduction: There are so many natural resources are available in India. 

Compare to world natured resources are very less in India. Although our 

nation using these resources and become a developing country. For the 

sake of development we using our natural resources in very large 

problem and it is near to an end. So….. What we will give to the next 

generation? Think yourself. Shortage of energy is one of the big problems 

in our country. So to overcome on this problem we create one machine in 

our school. That is “MULTIPLE MACHINES”. 

It is multipurpose useful machine. Now a days we all are facing one 

important problem that is scarcity of electric energy. To overcome this 

problem we create one machine in our school. 

By using the less muscle energy we can make many works. Now a day's 

demand of electric energy is more than its production. 

Rural areas are suffering from lack of electricity. We can't able to perform 

our works in the field of agriculture, industrialization and electric home 

appliances regularly. Pry using this machine we fulfill our day today's 

demands. 


1. Pumping the water from well or tank etc. 

2. We can prepare this machine in very low-cost. 

3. We can use this machine for wood cutting. 

4. It is use for grass cutter as a fodder to animals. 

5. For the comfort of human being fan is also in this machine. 

6. Useful for coconut kernel grate. 

7. Useful to sharpen the knife and agricultural equipments. 

8. We can create a rope on this machine. 

9. We can produce the electric energy.

ECO FRIENDLY WATERLESS 

TOILET- USEFUL 

AGRICULTURAL PRODUCT 

The total number of families in our village area is about 

2361 out of this only 138 are using toilets. Even though 

village Panchayat took so much of measures they failed to 

eradicate open defecation and abundance use of chemical 

fertilizer to land due to illiteracy, poor conditions of 

people and scarcity of water, still 2230 families are using 

open defecation and chemical fertilizers to land. 

By surveying 100 houses, I came to know that many are 

suffering from problems like Polio, TB, Malaria, Cholera 

and many other diseases due to harmful bacteria's present 

in faeces and over use of chemical fertilizer for forming is 

not only polluting ground water level but also polluting 

soil fertility. 

The project aims at developing small working model 

that function as to. 

1. Prevent diseases and promote health. 

2. Protect the Environment and Conserve Water 

3. Recover and Re-Cycle nutrients and organic matters. 

Eco friendly waterless toilet is a newly invented toilet that 

I made by using the natural resources, clothes and other 

materials that separates all the liquid and solid wastes of 

Human and converts to soil conditioner and to impress 

people the value of their own excreta collected in the 

toilet to be used in farming for rising crops.

ECO FRIENDLY WATER 

LIFTING MACHINE 

Introduction: This is the experiment to lift water in rural areas, 

where the flow of water is there. It can be applicable for small 

farmers to supply water to their forms and to household users. 

Now a day, we are facing lot of problems because of power cut, 

lack of natural resources and increasing price of those recourses. 

So the project has special well as user friendly concept. 


— Low cost 

— Eco-friendly. 

— No need to depend on any fuel or electricity. 

— Continues water supply. 

— Increases the level of underground Water. 

— Very much helpful to small farmers to maintain their farms. 

— Most useful in the areas where abundant flow water available. 


— Water lifting without fuel or electricity. 

— Eco-friendly 

— Easy construction. 

2012 

— Poor people benefitted from this water lifting machine. 

Automatic Water Lifting: When the water flows from the source 

by the pipe P1 and P2, water reaches to the foot valve C1 and 

hits the valve according to Newton's third Law, water returns 

with great pressure and hits non return valve C2 and valve gets 

opened. Water enters into the hydrum. Because of pressure due 

to air present in the hydrum, water is pushed towards valve C3 

with great speed and pressure. So it moves through the drip pipe 

P3 which is nearly 90 feet of height and water comes out by free 

end of pipe P3. To stop the procedure the gate valve G is turned 

off. 

Principle: Potential Energy stored in the water tank in the form 

of water is converts into kinetic energy by valve operations and 

flow of water.

now a day we spend money for students to see such places 90% 

students were unable to understand this we use resource full 

and what is its use? 

Preparation of Cement factory model by using waste materials, 

its using like lift technology to pass raw material on the belt it 

means cycle pumps are used as pistons by compressed air stored 

in rubber tube while stored air will transfer to turbines it 

generates electrical energy, this electrical energy is used to run 

whole plant 


1) It generates the Electricity. 

2) Saving's money. 

3) Using smoke alarm it Identifies and control of over emission 

of CO ,SO CO etc. 

2 2 


1) Air pollution will be identifying and controlling by using 

sensor circuits. 

2) Production of electricity by lift moment. 

3) How to use resources, control air pollution and generation of 

electricity these things develops Scientific attitudes among 

the students. 

Electricity generation by compressed air: 

2012 

Here the technology of lift moment is used. The air is 

compressed with the help of cycle pumps and stored in the 

rubber tubes, then the store air should be transferred to dynamo 

the electricity is produced with rotation of turbines here the 

mechanical energy is converted in to electrical energy, by using 

this electricity to use run the factories and saves the money. 

Identification and control of pollutant gases: 

The over emission of toxic gases like CO2,SO2,CO etc from the 

factories by using sensor circuit to detect and control the toxic 

gases. Which are emitted from the factories.

SAFTEY HOUSE 

Introduction: Solar energy is the radiant energy that we 

use in the form of heat and light. It is the ultimate source 

of most of the sources of energy that we use today it is an 

inexhaustible source of energy. Thus we can prevent 

energy crisis and make our mother earth pollution free. 

Working: It works on solar energy. The solar energy is 

converted into electrical energy. This electrical energy is 

used by the respective devices like smoke alarm, touch 

sensitive siren, rain fall indicator, mosquito repellant, 

listening bug etc. 

Advantages: instead of depending on the watchman we 

can install these devices and can protect our home from 

any sort of small or major disaster. We can make the best 

use of non-renewable source of energy. Not very 

expensive. We can provide protection sweet home.

SMART SECURITY SYSTEM 

2012 

Introduction: As we know today defence is the backbone of the 

country and they have to face a lot of risks and over come in various 

fields such as security, surveillance, diffusing of explosives etc. Hence 

we have come up with the model that can assist our military force to 

overcome the above mentioned problems. 


— Survey the suspicous area. 

— Updates the images of every motion of enemy. 

— Updates the wind speed. 

— Robotic arm grabs or difuses the suspicious objet. 

— Saves the soldiers from natural disasters like cyclones. 

— Detects the landmines planted. 


— Saves the lives of the soldiers. 

— Soldiers can take preventive measures against natural calamities. 

— Soldiers need not step onto the landmines and lose their lives. 

— Difuses the bomb in barren places and saves the lives. 

Metal Detector:- The metal detector used here is the basis of a Hartley 

oscillator. When the detector comes in contact with any of the metal 

the inductance of the search coil changes and there by producing the 

beat frequency that is amplified by the amplifier and transmitted 

through the FM transmitter. The signals can be received using the FM 

receiver in the cell phones . 

Wind Speed Detector:- This circuit consists of two ultrasonic 

transceiver. The transmitter transmits the ultrasonic frequency which 

is reflected back by the wind and is received by the receiver. the code 

is written to calculate the time taken between these two processes and 

thus the speed of the wind is detected. 

The Arm:- The arm is horizontal axis arm in which arrangements are 

done to pick the objects that are on the ground. The arm is equipped to 

rotate 360',move up and down adjusting to the suspicious object 

found. The wrist can move about 90' for additional grip after grabbing 

the object. 

Surveillance Camera. The camera is mounted on a pole which is 

capable of rotating in the desired direction and hence one can view the 

entire area under surveillance. A TV tuner card is used to view the 

continuous videos.

BIO-GAS AND 

ORGANIC FERTILIZATION 

Introduction: The main energy sources being used by 

us.are coal petroleum natural gas and recently nuclear 

fuels. All these sourses are virtually non renueble 

sourses.These have accumulated in nature over a long 

time and can't be replaced quickly.the fear of running out 

of earths energy resourses has created a sort of energy 

crises.Improwing the bio digester we can reduce the 

energy crises.Bio gas is typically refer to a gas produced by 

breackdown of organic matter in the obsence of oxygen. 


— It reduced the Energy crises. 

— It produces Methane gas used as a fuel. 

— It saves Money. 

— It provides Safety cooking. 


— It may be viewed as the future source of fuel for 

domestic purpose.. 

— It encourages youngstars towards the Organic 

fertilization. 

Biogas and Organic Fertilization :- 

2012 

The equal mixture of water and cattle dung is poured into 

the inlet portion of Biodigester. It deposited into bottom 

portion called as Digestive portion. After twenty five to 

fifty days absence of oxygen it creates anairobic 

furmuntation and produce the Methane Gas. And it 

collects on the top of the biodigester i.e. called as Gas 

collector. Increasing the collection of the biogas pressure 

created on the slurry. Then slurry moves through the 

outlet portion. This slurry is very essential to the plants 

and also free from the injurious gases.

MANUAL WATER 

LIFTING PUMP 

Introduction: We are facing scarcity of Electricity in our 

state, due to this our routine activities will get disturbed, 

among them lifting the water from the under ground tank 

is a very risky job . To avoid this problem we can lift the 

water by using manual power without electricity. This 

system can be used in garden, in house and a many other 

domestic purpose. 

Advantages of the project: 

It saves electricity. It gives a good exercise to our body. It 

saves time(informally waiting for power supply). It saves 

money(Electric bill). It avoids severe accidents like 

Electric shock and Fire. 


It is manually operated machine. There is no age limit to 

operate this aperture. We can assemble this aperture at 

low cost. 100% eco friendly. Saving 1 unit is equal to 

production of 2 units. 

Operation: In this system muscular energy is converted in 

to mechanical energy. 

When we started peddling the wheel the fan in the pump 

rotates by the help of pulley, which is connected to the 

rim with the help of string resulting in the increasing of 

RPM of the air tight fan, which will pull the water from 

underground tank and push towards the over head tank. 

When the number of rotations increases the pulling force 

also increases respectively.

DRY RUNNING PREVENTER 

FOR IRRIGATION PUMP SETS 

Introduction of Project: This project aims at developing 

cost-effective auto-stop mechanism for three phase and 

single phase irrigation pump sets, which would cater the 

people of the society, mainly farmers of the rural area. The 

mechanism uses simple technique and very commonly 

available resources. It can be easily customised according 

to the requirement. It is easy to install, operate and can be 

assembled by user himself. The idea has been tested 

successfully and working prototype is developed. 

This mechanism prevents irrigation pump sets from dry 

running. Whenever the water level of the pond reaches 

pre set value the pump turns off automatically, also we 

can set the required level of water for which the pump 

should turn off, by dooing so we can supply the water as 

per required. 

Innovation and usefulness: 

— Low cost (costs around 100/-) 

— Easy to operate 

— Zero maintenance 

— Construction is simple 

— Light in weight 

— Can be assembled locally 

— Reliable operation 

Advantage: 

— It saves the considerable amount 

2012 

— We can utilize water as per our requirement without 

wasting.

NEAR INFRARED IMAGING OF 

SUBCUTANEOUS VEINS (NIISV) 

Introduction: It is a part of co-curriculum to study the various 

frequency spectrum bandwidth & their applications in day to 

day life for wellness of the human being & mankind, here we 

have chosen very low frequency bandwidth using IR LED. Any 

treatment related to vein becomes really difficult if medical 

practioners are not able to locate the required vein, hence the 

main objective of this project is to develop a low cost imaging 

device that could help to get the image of the subcutaneous veins 


— It is not Harmful, it is free from shocks and high penetration 

power With minimum cost Maximum usage 

—It is based on a cost effective and simple system 

—It is a major use in Neonatal and Pediatrics 

—Mainly to understand the electromagnetic spectrum & their day 

to day life 

Near Infrared Imaging of subcutaneous veins : Working 

principle of this instrument is based on varied optical properties 

of vein ( de-oxygenated hemoglobin) & surrounding tissue, & by 

optical properties we mean the absorption, reflection & 

scattering of incident Infrared radiations by these tissues. 

Challenging aspects: There are devices available to locate veins 

but they are very expensive and thus vein detection is out of 

reach for many hospitals in India that cannot afford the cost & 

burden of the existing devices. 

Future work: 1. The real time Processing of streaming video can 

be done to enable seamless operations, with real time projection 

of video back in to the same spot being more beneficent. 

2. The device can be integrated into a small portable package 

with a plug and play operations having a embedded chip that 

does all the process. 

3. The same NIISV embedded chip with one IR LED in mobile 

phones can help the nurses, doctors (paramedical) to detect the 

subcutaneous veins anywhere any time. 

4. Mobile torch with NIISV can also be made with beep alarm

PERMUTIT PROCESS 

I am glad to say these Permutit Process helps to us softening 

of hard water into soft water. Naturally occurring Sodium 

aluminium silicate is called “Zeolite”. Artificially prepared 

sodium aluminium silicate is called “ Permutit”. 

The principle involved in this process is to convert the 

dissolved salts of calcium & Magnesium into insoluble 

calcium & Magnesium permutits, respectively. This is done 

by exchanging the base ion radicals such as Ca++ & Mg++ 

with the base ion Na+ of sodium aluminium silicate. Hence 

this process is also known as 'Base Exchange Process'. This is 

carried out by passing hard water through the layers of 

Zeolite / Permutit. This method removes both temporary 

hardness & permanent hardness. 

Soft water – water easily gives lather with soap. 

Hard water – water doesn't give lather with soap. 

Causes for Hardness: - 

Water contains dissolved salts of Ca++& Mg++ ions. 

Changes Occur in this process :- 

Sodium permutit + Calcium chloride Calcium permutit 

+ Sodium chloride 

Sodium permutit + Magnesium sulphate Magnesium 

permutit + Sodium sulphate 

Importance of this process : 

1) This is an easy & economical way of softening of large 

amount of hard water into soft water. 

2) The hardness is more or less completely removed by this 

method. 

3) This method is very useful for rural areas people. 

4) It is also useful for industries.

ADVANCED SOLAR COOKER 

Introduction: Advanced Solar cooker is based on renewable 

source of energy. Solar energy is used to cook the food. Here 

solar energy is converted into both heat and electrical energy. 

Source of Inspiration: To convey the use of renewable source 

of energy more and more. 

Materials use: Wooden box, mirror, thermal conductor plate, 

glass slab, gasket, resistance wire, solar panel, cooking vessel. 

Working of the Model: The wooden box is covered with 

thermal conductor plate in the inner side. Outside it is coated 

with black paint to absorb more heat from the sun. Top 

surface of the wooden box is closed with glass slab so that 

infra red radiation will remain inside the box. Mirror is 

placed so that light rays falling on the mirror will be reflected 

in to the box. The resistance wire is placed inside the box 

which is connected to the solar panel. Solar panel converts 

solar energy into electrical energy and then to heat energy. If 

helps to increase the quantity of heat inside the box. One 

more advantage of the advanced solar cooker is that even it is 

kept inside, the temperature inside the box remains almost 

2 

constant due to resistance wire. The theory is H=I RT, 

Where H – heat produced 

R- Resistance 

T- time 

I – Electric current 

Applications :- 

* used to cook the food 

* Used to cook food grains like rice, vegetables and dhal etc. 

* It is also working as “ Hot Box” . 

* It is echo-friend device. 

* Device based on renewable source of energy.

ELECTRICITY FROM 

HIGH WAYS 

Introduction Today we are in a situation of energy crisis. Our 

main dependency for power is Non- renewable resources like 

Coal and Petroleum. At this juncture we are in need of NEWER 

WAYS TO USE RENEWABLE ENERGY RESOURCES. This 

project is mainly about use of both wind energy produced by the 

fast moving vehicles and the friction of wheels on the surface of 

the road being converted into electricity. Wind energy is 

converted to electricity by the use of vertical wind turbines. 

The electricity can be generated by moving the vehicles on the 

roller mechanism. The shaft will rotate under the road. This 

shaft rotates the dynamo. It generates the electricity. The 

generated electricity is stored in the battery and it is utilized. 

Main advantages of the project :- 

India now needs alternative sources of energy at this juncture:- 

* This model helps to minimize the use of land as the turbines 

are fitted on the road dividers. 

* This model helps to produce electricity irrespective of seasonal 

changes 

* The energy produced can be stored in batteries and later used . 

* As the model uses the wind produced by fast moving vehicles 

and the frictional force of the wheels of the vehicles. It is the 

model which uses the complete energy of the moving vehicles to 

get energy. 


2012 

*The idea of using vertical wind turbines to use the wind energy 

produced by thevehicular movement 

*The idea can be exteded to moving vehicles where the heavy 

vehicles like trucks and buses can be fitted with small wind 

turbines which can convert the wind blowing into the vehicles 

during their transit can be used to produce electricity. 

* This concept can be extended to small vehicles whose wheels 

fitted with spokes, can use wind produced by rotation of wheels 

to run tiny wind turbines and get energy.

Introduction: Nature has provided to mankind energy in 

various forms. They are grouped into renewable and nonrenewable 

sources of energy. Our main intention of this 

project is to conserve the non-renewable sources of energy 

by using renewable sources of energy with the help of 

solar panels and motors having high efficiency. 


—It saves non-renewable sources of energy. 

—It provides the habit of generating electricity using solar 

energy which is free of cost. 

—It is an efficient approach of generating electricity at the 

load centre itself thereby we can save time, transmission 

gridlines and avoid power loss. 

—It can be used in the remote areas where the extensive 

transmission gridlines are not available. 


—It is the easiest method of operating the devices like 

power loom, lifts, cranes etc. 

—It is a pollution free process of producing goods in 

industries using motors. 

—It saves manpower. 

Applications of Motors to Save Non Renewable sources 

of Energy: 

By using Glaser' Idea, Motors, we can minimize the 

wastage of energy especially non-renewable sources of 

energy thereby we can save the sources of energy for our 

future generation.

WIND-CUM-HYDRO 

ELECTRIC POWER 

GENERATOR 

Introduction: A wind-hydro system generates electric energy 

combining wind mills and pumped storage of water Wind and its 

generation potential are inherently variable. However, when this 

energy source is used to pump water into reservoirs at an elevation 

(the principle behind pumped storage), the potential energy of the 

water is relatively stable and can be used to generate electrical 

power by releasing it into a hydro power plant when needed. The 

combination has been described as particularly suited to remote 

places that are not connected to larger grids. 

Main adavantages of the project 

— This project is eco friendly 

— It involves simple technology This project involves simple 

technology 

— It involves least capital 

— It involve both wind technology and hydro electric technology 

— Maintenance free 

— It will help the people who are in remote places, which are not 

connected to larger grids 

— It can be installed at tanks, channels, rivers, lakes and also at 

sea shores which are attached with a small elevation point 

Importance of the Project 

2012 

— Wind energy is used to lift water to an elevated reservoir;- 

A series of wind mills with piston pumps are mounted around or 

along the source of water, a reservoir of required capacity will be 

constructed on the elevation point. . Each wind mill will pump some 

amount of water into the reservoir continuously and independently 

depending up on the rate at which wind blows. 

— Hydroelectric technology is used generate electricity by using 

kinetic energy of water :- 

After storage of certain amount of water in reservoir is allowed to 

flow on the turbine, in turn kinetic energy of water is converted in to 

electric energy in the generator connected to turbine, after the 

generation the water is allowed to flow to the same source of water.

Introduction: The aim of using cow dung in modern way 

1) Conservation of plants in minimum expenditure 

2) To get quality fuel by making minimum expenditure by 

using agricultural wastes. 

3) To get good quality fuel using cow dung in scientific way. 

4) Eradication of mosquitoes by using cow dung. 

5) Producing electricity by using cow dung. 

Materials required for experiments 

1) Dung of animals, 2) Sheep excreta 3) Poultry excreta, 4) 

Aluvilial soil, 5) Agricultural wastes, 6) Neem leaves, 7) 

Samrani powder 8) Dead shells etc 

Short explanation: Environmental pollution has become the 

problem of the world today. To eradicate this problem to 

conserve the plants and protect from diseases we use cow 

dung, sheep wastes, poultry wastes and urine of cow. 

Everybody knows that dung cakes are used as fuel, in rural 

area. In the same way agricultural wastes may be used to 

prepare agricultural cakes and used as fuel. Further dung may 

be used in more scientific way. To prepare fuel gas called 

gobar gas. It is prepared by fermenting cow dung in scientific 

way, the gas released is used as fuel. Further we exhibit that 

the cow dung may be used as mosquito coils in a natural way 

to kill mosquitoes and insects. Without cost of using cow 

dung we can produce electricity and also we use for mobile 

battery and car battery charging also.

BHARATHIYA KALAGANANA 

PADDHATHI (INDIAN CALENDAR) 

Introduction: Calender is a part and parcel of our life. We use now 

the British calendar which has 12 Months an year as January, 

February etc. In ancient India, we were using a calendar based on 

the position of sun and the moon with respect to stars in the sky as 

visible from the earth. The Months of an year are named bv the 

name of the groups of the stars like Mesha, Vrishabha - -etc. We are 

proud of our ancestors for adopting a very scientific way for calendar 

thousands of years ago. This model helps to understand the 

structure of Indian calendar (Bharathiya Kalaganana Paddhathi). 

Main advantages of the project (model) :- 

— It enables to identify the stars in the sky very easily. 

— It enables to understand the motion of Earth in its axis and 

around the Sun, and the motion of moon aroud the Earth. 

— Many people follow this calendar but very few know the logic or 

sciece behind this. This model shows how scientific is our 

calendar. 


— Promotes the study of stars or sky. 

— Eradicates blind believes about astrology. 

— Know our ancient system of calendar. 

— Apriciate our ancient system of calendar. 

Bharathiya Kalaganana Paddhathi( Indian Calendar) : 

In ancient India, we were using a calendar based on the position of 

sun and the moon with respect to stars in the sky as visible from the 

earth. There are two systems of fixing days or months of an year. 1) 

Souramana paddhathi 2) Chadramana paddhathi. 

1) Souramana paddhathi 

2012 

In this system according to the position of sun in the sky as we see 

from the earth, the days and the months of an year is fixed. The 

path in the sky on which sun and the moon move as we see from the 

eath is calles 'Kanthi Vritta'. It is devided into 12 parts( Rashi) and 

they are named as an imaginary figure appears in the sky like Mesha, 

Vrishabha – etc.

AUTOMATIC RAILWAY GATE 

Introduction : 

It is the cheapest & safest device to prevent accidents 

while crossing over the no man railway gate. We have to 

feel fearless, accident free experience in crossing no man 

railway gate. 

Main advantages of the project : 

This model gives more security & safety measures while 

travelling in no man railway gate, because it gives warning 

beep sound as well as automatically closes the gate, if 

train comes from railway station. 


We have observed in many news papers, so many 

accidents happen in unman railway crossing. That's why 

we have to think and prepare the model which is less cost 

and safer among rural areas. 

If the train came in turning, we may get confused. So that 

this device gives alarm sound and closes the gate 

automatically. After going the train from no man railway 

gate it opens automatically with no sound alarm. This 

gives more safety travelling in unman railway gate.

MULTI-PURPOSE 

SOLAR POWER CART 

Introduction: Now it is time to go for Natural, Inexhaustible and any 

ware freely available energy source to our day to day requirements. In 

this direction it is my small effort to introduce a Cart Model running by 

never exhaustible solar energy. 


1.Doesn't need exhaustible energy which may not be available in future 

even at high expense. 

2. It saves a lot of foreign exchange. 

3. Eco friendly 

4. It reduces requirement of hard working labour who are not sufficiently 

available nowadays. 

5. Doesn't need roads. It runs on track or wire rope etc. 

6. it can be adapted in Western Ghats and in similar areasfor agricultural 

activities where, roads cannot be constructed due to forest and rivers 

protection. 

7. It saves the labour and cost of production. 

Importance of the project 

At present all internal transportation in the field of industry and 

agriculture are running by the devices operated with the petrol, diesel or 

natural gas (Hydrocarbons). But the needs of the time is to reduce 

considerably the use of these exhaustible energy. The technic of my Solar 

Power Cart can meet this requirement. 

Also the damage to our eco system caused by burning hydrocarbon for 

energy can be reduced by investing in my Solar Power Cart Technic. 

Improves the ruralagricultural activitiesby reducing dependence on hard 

labour force which is not available nowadays. 

Operation 

My Schematic Solar Power Cart model is working on the following 

principle. 

1. Running on the track from point "A" to Point "B" and vice-versa. 

2. Load at Point "A" and unload at Point "B"and vice-versa. 

3. 3 V battery cell, 

4. Solar panel (for illustration only). 

5. Motor 3 Amp. 

6. Gear Box and four grooved wheels 

7. Carries around 5 Kg load.

CONSERVATION OF ENERGY 

Introduction: Now a day the conservation of energy is very 

important. The energy can neither be created nor be destroyed 

but it can be converted from one form of energy into another 

form. In this system we can using the Heat energy and 

muscular energy we can run all types of Buses, Railways, Cars 

and all types of machines also. 


—Fuel is not necessary for this purpose. 

—It generates the electricity. 

—The heat energy can be converted into mechanical energy 

and electrical energy. 

—It provides safety driving. 


—Heat engine 

—Wind energy. 

—Lathe machine. 

—Drilling machine. 

Heat Engine:- Heat energy can be converted into mechanical 

energy is called Heat engine. In this we can use the boiler. The 

boiler can be heating then water vapors is moved to a metallic 

strip then piston and wheel can be moving then buses, trains 

etc. can be run. 

Wind Energy:- The moving air is converted into energy called 

wind energy. The wind energy can be used for rotating the 

blades by using mechanical energy. Then by this electricity 

will be generating. 

Lathe Machine:- By using the muscular energy to run this 

machine we can give shapes for many iron rods and wood 

pieces. By this we can do the top threading also, etc. 

Drilling Machine:- By using the muscular energy, we can hole 

the iron rods and wood pieces

LIFTING WATER 

WITH VACUUM 

Introduction: India is agriculture based country. We need 

water for all agricultural needs and power generation. 

Even though power can be generated from thermal and 

nuclear energy, hydroelectric power projects are quite 

common. But cost of these projects is very huge. 

Here is a simple project which lifts water with vacuum. 

The lifted water can be used for household purposes, for 

agriculture, in industries and for generation of power. 

The project incorporates simple mechanism. Here vacuum 

is created artificially using easily available cheap 

materials. To fill the vacuum, water rushes to reach the 

top. The lifted water can be used for any purpose. 

The pressure of the water can be increased by connecting 

pipes in the decreasing order. The water with pressure is 

made to fall on the turbine which generates electricity in 

small amount. 

Importance of the Project 

1. Water can be lifted from wells, bore wells or sumps 

without any energy. 

2. Works on the principle of siphoning. 

Advantages: 

1. Mechanism is very simple. Easily available materials 

are used. 

2. Cost is less. 

3. No energy is required. 

2012 

4. The lifted water can be used for household purposes, 

for agriculture, in industries and for generation of 

power.

ELECTRONIC CONFIGURATION 

Introduction: As we know, protons have a positive charge 

and electrons have a negative charge. Free (unattached) 

uncharged atoms have the same number of electrons as 

protons to be electrically neutral. There is a ranking or 

hierarchy of the shells, usually with the shells further 

from the nucleus having a higher energy. As we consider 

the electron configuration of atoms, we will be describing 

the ground state position of the electrons. When electrons 

have higher energy, they may move up away from the 

nucleus into higher energy shells. As we consider the 

electron configuration, we will be describing the ground 

state positions of the electrons. 

What have I done in my project? : 

1.A hydrogen atom has only one proton and one electron. 

The electron of a hydrogen atom travels around the proton 

nucleus in a shell of a spherical shape. 

2.The two electrons of helium, element number two. 

Being an inert element, it indicates that shell is full. It has 

2 electrons in its only outermost shell. 

3.Carbon has 2 electrons in first orbit and second orbit has 

4 electrons . 

4.Neon has a full shell of eight electrons in the outside 

shell, the L shell, meaning the neon is an inert element, 

the end of the period. 

5.Argon, element eighteen, has two electrons in the K 

shell, eight in the L shell, and eight in the M shell. The 

fourth period begins again with potassium and calcium, 

but there is a difference here. After the addition of the 4s 

electrons and before the addition of the 4p electrons, the 

sequence goes back to the third energy level to insert 

electrons in a shell.

WATER OVER FLOW ALARM 

Introduction: Millions of liter of water and numbers of 

Units of current is wasted daily throughout the world 

because motors are not turned off when the tank filled. 

Water overflows from Overhead tank or underground 

tanks and is wasted. It happens because people are not 

able to know the level of water by any means. So it would 

seem extremely important to have a device which gives a 

warning before tank fills and it enables turnoff the tap on 

time. This simple device has great role to play to save 

fresh water which is very precious at present in every part 

of the world. 

Requirement: 2 Resistors, 2 Transistors, Connector, 9 Volt 

Battery & a Speaker. 

Mechanism: It's a open circuit. Two end of the wire to be 

fixed just below the overflow level when water reaches 

this level it conducts electricity and circuit gets 

completed, hence alarming starts. 

Accountability: Hardly the device cost about Rs.100 but it 

saves about 10 units of current & minimum thousand liter 

of water per house 

Application: Indicator (Speakers can be replaced) can be 

modified with Light, Auto phone call, auto turn of switch. 

Result: It saved about 50 units of current & minimum ten 

thousand liter of water of our school. 

Impact: Millions of liter of water can be saved along with 

electricity.

IMPROVISED EXPERIMENTS- 

PHENOMENA OF LIGHT 

2012 

Aim: This project aims to experimentally demonstrate some 

phenomena exhibited by light such as reflection, refraction and 

total internal reflection using easily available, cheap and waste 

materials. 

Reflection of Light: In reflection of light, the laws of reflection are 

experimentally proved using a rotating plane mirror ,a ray box 

having a single slit and a torch. A single ray coming from a 

stationary ray box is allowed to fall on a plane mirror which can be 

rotated about a vertical axis. When we rotate the plane mirror the 

angle of incidence changes and at once we can measure the angle 

of reflection. 

The idea of principal focus of spherical mirrors cannot be 

visualized easily. Here I improvised an apparatus not only to 

visualize the principal focus but also to prove that R=2f (radius of 

curvature is twice the focal length). I made a ray box using a comb 

and torch from which a beam of light rays comes. For concave and 

convex mirror I used a tongue cleaner (made of stainless steel) 

which can be bent in different radii. When parallel rays from the 

ray box falls on concave side of the tongue cleaner it converges to a 

point and when it falls on the convex side, it diverges. There is 

also provision to measure 'r' and 'f' on the platform made of 

plywood. 

Refraction of Light: To study the laws of refraction and the 

principles of refraction, I made a semicircular transparent plastic 

bottle. Water is filled in the bottle. When red light from a laser 

torch is allowed to incident on the curved surface towards the 

centre of the bottle it goes without deviation because the ray is 

normal to the surface. But at the flat surface, it suffers deviation. 

We can measure the angle of incidence 'i' and the angle of 

refraction 'r' from the graduations on the platform of the apparatus. 

Using the same apparatus we can also prove the principles of 

refraction, can measure the critical angle and also can exhibit the 

phenomenon of total internal reflection. 

Optical Fibre: Optical fibre is a costly material, but cheaply I made 

an optical fibre using a plastic bottle. Water coming out through a 

hole made near the centre of the plastic bottle flows like a bent 

tube. When laser light is allowed to fall on this tube it bends along 

with the water column because of total internal reflection.

RICE DISTRIBUTION MACHINE 

Rice Distribution machine is a simple machine; used to 

distribute special rice to school children as a part of Mid- 

Day Meal scheme. Thus it helps to overcome the difficulty 

of distributing special rice throughout the day by 

manpower. 

This apparatus helps to distribute rice and cereals in an 

easier manner. Only two persons are enough to operate 

this machine. 

The mode of Working : When we drag the drawer 

completely inside, the rice is poured on to the bucket kept 

on the apparatus. A bag is kept near the outlet in the 

below portion. The drawer is pulled outside, Then a 

particular quantity of rice comes through the outlet which 

is collected in the bag. 

This is easy to built using locally available materials, easy 

to repair. It encourages energy conservation and maximize 

community independence from non renewable energy 

sources and it develops eco friendly attitude among 

people. The machine is of low cost, durable, practicable, 

no need of maintenance cost, easily moveable, less man 

power usage, eco friendly, no fuel consumption and 

enjoyable. It replaces a labour intensive repetitive task. It 

enables to do work with less muscular effort and with 

great speed. Thus the machine maximize the out put force 

to perform the task more efficiently. 

We know that the simple machines were the building 

blocks of our nation and industrialization. Thus it plays a 

vital role in the technology as well as the economical 

advancement of society. We can say that this apparatus is 

a new idea adopted by the child for the first time in 

Kerala.

CROSSING 

2012 

Introduction: What I have planned to do here is a model 

of an Automatic Railway cross. We know that the railway 

accident frequently happen in our country. It is mainly 

because of the carelessness on the part of the passengers 

and the railway authorities. My attempt here, is a model 

that can make railway journey safer and more 

comfortable, avoiding the frequent accidents. 

Functioning: The main part of this project is a loader. Four 

sensors have been installed in four different places, four 

kilometers away from the railway cross. Each sensor has a 

function of its own. When the train arrives at the first 

stop, the sensor installed there, gives a signal to the 

railway cross. When the train reaches the second stop, the 

sensor helps the check post to close the road along which 

the vehicles pass. When the train reaches the third stop, 

the loader rises and as a result, the road vehicles stop and 

the train passes. The function of the sensor at the fourth 

stop is to warn the train if there is any possibility of a 

danger. Thus my model helps the passengers and the train 

to be completely safe.

LOW COST HIGHWAY 

WIND GENERATOR 

Importance of the topic: India is facing acute energy 

shortage that impedes its industrial growth and economic 

progress. It is highly essential to tackle the energy crises 

through wise utilization of renewable energy sources like 

wind, solar, hydro, geothermal, tidal and biomass. 

Wind energy is a free, clean renewable resource of energy 

and so no matter how much it is used today, there will be 

same supply in the future. 

Outline of the Device: Low Cost Highway Wind Generator 

is a device to recapture the energy extended by vehicles 

moving at high speed in express highways. Also, these are 

places where wind keeps on flowing irrespective of 

seasons, day or night. These highways can become wind 

farms when vehicles moving at high speed cause much 

turbulence in the air. This energy can not be harnessed by 

conventional wind turbines. This requires turbines which 

are independent of the direction of flowing wind. 

Working: This device has specially designed blades which 

rotate the rotor from the wind generated. The kinetic 

energy of the wind is converted to mechanical energy. 

When the shaft is connected to a generator it produces 

electricity. This electricity can be stored in Nickel- 

Cadmium batteries and using light dependent resistors, 

we can illuminate pathways and tracks and also signals 

during night time and thus can avoid accidents. These 

turbines when mounted on both sides of highways can be 

excellent source of energy there. 

This model is definitely low cost, economical, nonpolluting 

and most importantly an environmental friendly.

SAFETY BUS 

Safety Bus is the bus which ensures safety of passengers 

by making rescue operations easy. The safety system of 

the Bus works according to "Pascal's law". For the working 

of safety system, pressure switches and bimetallic strips 

are attached on the body. Bimetallic strips make the fire 

rescue operations easy. It is used to convert temperature 

change into mechanical displacement. 

The materials used for the construction of the safety 

system include High torque DC Motor, Syringes, pipes, 

Bimetallic strips etc. 

A pressure switch is fitted on the side of the bus. When 

the bus overturned due to accident the pressure switch 

become on which works the motor and a pressure is 

exerted in the fluid tank and it is equally transmitted 

through the pipes into the syringes. As a result the top and 

one side of the Bus get opened. 

If the Bus catches fire the bimetallic strip bends and the 

safety system works as in the above case. 

The main advantages of this Bus are: 

i) Rescue operations become much easier 

ii) Compressed air can be used as an energy source 

iii) Manual effort is minimized

IR MUSIC TRANSMITTER 

AND RECEIVER 

IR Music Transmitter and Receiver works using infrared 

technology to transfer the music. 

Here we are using IR transmitter and IR receiver. The IR 

music transmitter works of a 9V battery while IR music 

receiver works of 9V to 12V battery. In the transmitter side 

we have a music tone generator ICUM66. The output of 

this is fed to the IR driver stage to get maximum range. 

The red LED flickers according to the musical tone 

generated, indicating modulation. Here, the electrical 

signals from the music player is converted into infrared 

light signal by infrared light emitting diode. For maximum 

sound transmission these hold be oriented towards IR 

photo transistor L14FI in the receiver side which converts 

the infrared light signals into electrical signals. Then the 

popular op-amp ICmA741 and audio-frequency amplifier 

IC LM386 expands these signals. In the receiver side we 

are using photo-transistor and its gain can be increased by 

potentiometers. The receiving music tones can be 

delivered through a loudspeaker switching off the power 

supply stops melody generation. This technology can be 

applied in wireless musical system, mobile gadgets, CC 

cameras etc.

The Concept of this model is based on Biogases theory 

under non traditional energy resources. Firstly dined 

production of Biogases and electricity by (i) Poultry beats 

(ii) pong amiya and jetropha seed cake (iii) human excreta 

To produce Biogases by poultry beats. I have done 

observation in chandraila poultry farm aurai (Mandla). In 

poultry beats gases has 73% CH 23% CO and 4% H . 

2 2 2 

When this gases passes through HooH Co and NooH 

2 2 2 

changes in No Co . 

2 3 

Biogas production by pong amiya and jetropha seed cake 

is done by me with help of guide teacher and Suresh 

Khartik (B.E.) seed cake is taken from Vijay Oil Mill, 

Bamhni Banjar (Mandla) for practical.

SOLAR POWERED GRAIN 

AND FLOUR CLEANER 

Structure : I have made a machine with direct supply 

solar powered. It has as storage 12v battery also which 

supplies the power. It has as funnel for introducing grain 

and flour in the machine. It has a sliding plate, strainer for 

flour and grain, two 12v motors and a fan. Once we have 

introducing the flour in the funnel, it goes to the sliding 

plate which pushes the flour into the strainer with the 

application of electric motor. The strainer cleans and 

separates. The impurities present in the flour again with 

the application of another electric motor the impurities 

are collected through separate outlet and cleaned flour is 

collected below similar method is used for cleaning grain 

but with addition of a motor powered fan. 

Advantages: 

nd

METHODS TO ENHANCE THE GERMINATION 

PROCESS AND BREAKING THE DORMANCY OF 

A DICOTYLEDONOUS SEED IN INVITRO 

CONDITION 

Synopsis: Our project deals with the seeds. Seeds remain 

in dormant state for some period. Dormancy of a seed may 

be defined as a condition in which germination or growth 

fails to occur even though external conditions appear to be 

favorable. 

During this phase the organ may be induced to resume 

growth by various treatments like application of water/ 

moisture, high optimum temperature, oxygen, etc. Under 

suitable conditions seed emerges from dormancy during 

which it becomes easier to induce resumption of growth. 

Seeds after harvesting are often stored in dry place for a 

long time during storage they remain dormant. Through 

our experiments we are trying to observe that how the 

germination process of some variety of dicotyledonous 

seed can be enhanced by application of certain chemicals 

externally, so that the farmers may be benefitted in future.

URINE WASTE 

RECYCLING PLANT 

Urine is considered a waste. This project aims at 

recycling and reusing urine for many secondary purposes 

like flushing the toilets, car wash, gardening and outdoor 

cleaning. In the first level, the collected urine is 

biologically stabilized by using aerobic bacteria. In the 

second level, the bacteria are removed from the stabilized 

urine by using a simple technology. In the third level, the 

suspended particles present in the treated water are 

trapped in the graded sand and smell is absorbed by 

activated carbon filter. Now it is no more urine but usable 

water.

FORMATION OF 

ENERGY BY REUSE 

FORMATION OF ENERGY BY REUSE 

Now a day the country faces serious crises of power 

shortage. We present a project where in daily life we can 

generate electricity by water while it gets transported from 

ground to top and again from terrace to individual flat in 

down wards at high rise building. Here we use rules of 

transformation of energy and law of conservation of 

energy. 

CONSTRUCTION / WORK: 

— Waste water from building and factories gets purified 

by physical form, chemical and biological process and 

use for plantation in our surrounding. 

— From garbage different types of substances like organic 

& inorganic, biological wastage convert into biogas. 

— Wind energy, solar power is useful conventional 

energy sources in 21st century. 

USE: 

2012 

— Fuel cost reduces substantially in daily life 

— Environment gets protected from pollution, diseases. 

— Steam gets converted into water and rain useful for 

farming. 

— At the time of energy conversion requirement and 

utilization gets balanced. 


443

Process of Purification: 

1. First collect contaminated water from kitchen in 

container. 

2. Take filter paper which is special type made by 

cellulose of paper pulp and human hairs. 

3. Human hairs contain carotenoids which have number 

of Isoprene units. 

4. Isoprene units and oil impurities attract each other as 

both of them are unsaturated compound. 

5. Gaseous impurities, odour and colour are removed by 

using sand and charcoal by adsorption method.

NON- CONVENTIONAL ENERGY 

GENERATION SWING 

ELECTRICITY GENERATION 

Energy crisis is due to two reasons firstly the population 

of the world has been increased rapidly and secondly, 

standard of living of human being has increased. 

Therefore, we have to investigate some approximate, 

alternative, new sources for the power generation, which 

is not depleted by the very few years. 

Firstly we have to generate the swing, we get the 

reciprocating action in central movable shaft. We transfer 

this motion to freewheel. Both wheel are connected on 

same shaft so it is transferred to wheel. As wheel rotates 

the generator rotates in its definite ratio i.e. 36:1. This 

power is used to glow the CFL bulb if 5 watt's, through the 

inverter. 

Advantages: 

1. Easy maintained.

I have used Three Simple principles in system: 

1. Fluids flow from higher level to lower level. 

2. Substances drop down due to gravity & weight. 

3. M.C.B. Switch operates conversely than normal switch. 

System Comprises of :- Upper pet bottle (No. 1) is 

suspended to knob of M.C.B. switch controlling power 

supply to water pump. PVC pipe connects Terrace tank 

overflow pipe & pet bottle (No.1) When Terrace tank 

receives pumped water to predefined maximum level, 

water has no way, but run down through PVC Pipe into 

pet bottle No. 1 Weight of water in pet bottle No. 1 pulls 

down knob of M.C.B. switch from 'ON' to 'OFF' position & 

stops pump operation. 

Buoyant pet bottle (No. 2) is suspended to M.C.B. switch 

knob by a non corrosive string of predefined length. This 

Buoyant pet bottle (No.2) is sealed & floats on water as it 

contains considerable amount of air along with water . 

When water reaches lower predefined level, buoyant pet 

bottle (No.2) by its weight, pulls down M.C.B. knob from 

'ON' to 'OFF' position immediately to stop pump operation 

and protect against dry run. 

System is capable of saving precious Water & Electricity 

100% without any failure and also protects pump against 

voltage variation and dry run. 

I am sure that my system will definitely serve the society 

and nation to save water and electricity which are crucial 

& need of the hour.

SAVE ENERGY 

Aim – Saving of Electricity through reduction in 

Electricity consumption and cost. 

Material – PIR/S – passive infrared receiver sensor, Drive 

Circuit, Rellay Circuit, Bulb, Tinted Texture paper. 

Procedure – When a person enters into the home bulb 

glows. PIR gives information of person entering into home 

to the drive Circuit. Drive circuit increases the energy of 

PIR and it transfers information to relay circuit. Rellay 

Circuit acts as a switch which put on the bulb without 

touching the switch. Street lamp will remain switch off in 

the day time and will be on at night. 

Observation – It senses the movement of the person 

within the range of 6m area. It reduces the cost of multiple 

wiring. This device on/off on the sensing of the movement 

of the person. This it saves the Energy.

Samples of banana peels, banana peel biomass briquettes 

(homemade), and coal are burnt in the charcoal stove and 

heat the aluminum pan with water. Water temperature is 

measured over time and compared. 

Biomass Briquettes 

A briquette (or briquet) is a block of flammable matter 

used as fuel to start and maintain a fire. Common types of 

briquettes are charcoal briquettes and biomass briquettes. 

Biomass briquettes are a biofuel substitute to coal and 

charcoal. The most common use of the briquettes are in 

the developing world, where energy sources are not as 

widely available. 

Biomass briquettes are mostly made of green waste and 

other organic materials. They are commonly used for 

electricity generation, for heat and as cooking fuel. These 

compressed compounds contain various sorts of organic 

materials, including rice husk, ground nut shells, 

municipal solid waste, agricultural waste, or anything that 

contains a high nitrogen content. The actual composition 

of the briquettes varies by area due to the availability of 

raw materials. These briquettes are very different from 

charcoal because they do not have large concentrations of 

carbonaceous substances and added materials. Compared 

to fossil fuels, the briquettes produce low greenhouse gas 

emissions because the material used is already a part of 

the carbon cycle.

FRIDGE MODEL 

WITHOUT ELECTRICITY 

Fridge Model without Electricity 

To make this useful fridge first we should take wooden 

planks. The door, top and the bottom shelf is made up of 

light weighted and water resistant wood. The both side 

and back of the fridge is covered by charcoal & the wire 

gauze should be properly attached to it. At the end we 

should keep plastic tray filled with cold water at the top of 

fridge. Then we drop one end of thin cotton ropes in tray 

and the other end should be kept on side wall of the fridge 

so that, the ropes would connect with the charcoal. As 

soon as the rope connects with charcoal, water will 

continuously fall on charcoal by capillary action. Keep the 

maximum number of cotton ropes so that all charcoal gets 

wetted. For the Evaporation of the dripping water on 

charcoal the heat inside the fridge is used. This process is 

continuous and the inside temperature of the fridge is 

maintained low, and fridge remains cold. This fridge is 

useful in the remote areas and by which we can achieve 

the purpose of “SAVING ENERGY”. 

Benefits : 

— No use of electricity 

— Does not cause pollution 

— It is portable 

— Can keep food fresh for longer time

Subject: Polymer Organic Chemistry. 

What we need? : 

1. Use and throw glasses or thermocol. 

2. Organic volatile solvent preferably benzene or toluene. 

Principle: In preparing our multipurpose coating we have 

taken the advantage of two fundamental principles of Organic 

Chemistry. 

i) Like dissolves in like:- 

Things like thermocol, use and throw glasses etc. are 

composed of organic polymeric substances like polystyrene, 

polyethene etc. According to the above mentioned principle 

these materials are soluble in organic solvents. 

ii) Organic compounds (and hence solvents) have low 

melting point and boiling point:- 

Because of very weak intermolecular forces (called 

Van der Waal forces) in organic compounds they have low 

M.P. and B.P. Many of the organic solvents are volatile. 

Process:- Use and throw glasses (or thermocol) is dissolved 

in volatile organic solvent like benzene or toluene. 

Saturated solution of a polymeric substance (use and throw 

glasses or thermocol) in toluene or benzene is prepared. 

Generally 100 ml of benzene or toluene can dissolve 2ft X 2ft 

of thermocol sheet (2.5cm thick) or 13 to 15 use and throw 

glass (small tea cup). 

This saturated solution is then evenly spread on RCC slab 

and subjected to sun-drying. On complete evaporation of 

solvent we can obtain waterproof coating of desired 

thickness. We can adjust the thickness of layer by redepositing 

a new layer on previous layer. 

Same solution can also be used in laminating different things 

like paper, I-Card etc. It can also be used to give a protective 

layer on wooden plates.

'Rat Trap Brick Wall' is a craft of building wall. It is 

different from the traditional brick wall. It has many 

advantages over the traditional wall. In these days Rat 

Trap Walls will save the construction costs to a 

considerable extent. 

'Rat Trap wall' is a wall built by bricks with a gap within 

due to this gap we can save bricks, sand, cement, mortar 

and the labour (See the Picture). 

Today construction cost is rising higher and higher. For a 

common man, building house has become a dream. It has 

become nearly impossible for a common man to build a 

house because construction costs have reached the sky. 

To a common man, 'Rat Trap Wall' Construction can help 

to build a house at a minimum cost. This type of 

construction is affordable to both rich and poor people. 

Even Government housing schemes will be benefitted by 

this type of construction. In place of 100 houses, the 

government can provide finance to 125 house if Rat Trap 

Construction is followed.

The title of the project is to make eco-environment plastic 

from corn-flour (corn starch). The idea behind these is to 

provide an alternative in the place of non-degradable, 

harmful pollutant that is chemically produced plastic. 

These plastic can be made at household level as well as 

industrial level also. The manufacturing of these plastic 

requires corn flour, baking soda, Vinegar, glycerin, etc. For 

making these plastic, we have to go step by step and then 

finally dry the gooey mixture so obtain, in sunlight 

during day or in a cabinet heater in industries. 

These plastic has very useful properties. It is a biodegradable, 

eco-friendly and not harmful to the nature. It 

can be use in making plastic bags, Plastic-bowls and 

plastic material, if higher research is done on these goal. 

It has very useful properties in physical as well as 

chemical. It can take place the today's plastic in next early 

years, if proper research is done in India.

TO REUSE THE NUTRITIONAL 

CONSTITUENTS FROM MILK WHEY — 

LIQUID WHEY DRINK 

“A DRINK FOR ALL OCCASION WITH RICH 

"NUTRITIONAL VALUE” 

My project t is “To Reuse of Nutritional Constituents from 

Milk WHEY Liquid”. Milk WHEY liquid is the fluid left 

over from the process of Paneer and Cheese making. This 

milk Whey liquid contains 4.5 % Lactose, 0.7 % Total 

protein, 0.7 % Minerals, 0.1 % Citric acid and 94 % Water. 

Many times I observed that, people prepare paneer and 

disposes the remaining liquid which is nutrient. Then I 

started thinking over the reuse of WHEY liquid. I did 

survey of my town and observed that, the dairy farms and 

sweet marts prepares the milk product on large scale and 

they drain out the nutrient milk WHEY liquid. Then I 

thought that, can we reuse this milk whey liquid as a 

substituent for cold-drink? And the project come out in 

the figure. I collected the data from various Dairy and 

Sweet mart about their daily Paneer and Curd production 

and amount of milk whey drained. 

Under the guidance of my teacher, I prepared whey drink 

of different flavours and served it as a cold drink to my 

family members, relatives, friends and similarly to many 

students from our school. This was done for fifteen days. I 

got a positive response. From the survey report and the 

questionary provided to sweet mart owners, dairy owners 

and school children I observed that nutritional milk whey 

is the good source of protein to children. 

Finally I conclude that, “WHEY DRINK” is more useful 

and best way to Re-use of nutritional constituents. It is 

more beneficial, cheaper, easy to prepare and environment 

friendly cold-drink.

This model shows a simple solution to avoid street 

accidents in vehicles and collisions- i) Head-on, ii) Side, 

iii) Rear-end collision in Railways and on the level 

crossing gate, This Solution is an Anti-collision Device. 

The Loco ACD i.e. Anti-Collision device is fitted on the 

train and the ACD can be fitted at the railway crossing 

gates and in the big Vehicles like cars and buses etc. 

In this device the components used are - i) Sensors - a) IR 

and b) Photo diode, ii) LED, iii) ICs - a) Voltage regulator 

IC, b) IC-LM324, c) IC-L293D, iv) Capacitors - a) 

electrolytic capacitor, vi) micro-controller, vii) Battery, 

viii) Resistance and ix) the Motor. 

When a train runs on a track and other moving train or 

stalionary obstacle came across it ; there arises head-on 

collision ; but if the two trains have ACD ; then the 

sensors first detect the other moving train or obstacle in 

the field of its vision and the LED glows as the signal to 

the Loco-ACD fitted on the trains. The ACD acts to apply 

the Automatic brakes. when ACD acts ; the Sufficient 

Voltage is provided by Motor running IC-L293D to the 

motor which slows down the speed of trains and stop 

them at a safe distance. so the collision is avoided. Anticollision 

device fitted on other Vehicles can avoided road 

accidents & provide safety.

MAGLEV WIND TUBINE 

A maglev wind turbine of maglev windmill would use 

magnetic levitation to replace conventional bearings in the 

design of a wind turbine. A recent design was developed 

in China by Guangzhou Energy Research Institute under 

China's Academy of Science and by Guangzhou Zhougke 

Hengyuan Energy Science & Technology Co. ltd. 

The design claims to utilize winds with starting speeds as 

low as 1.5 meters per second (m/s) and cut in speeds of 3 

m/s. This could add 1000 hours of operation annually to 

wind power plants in areas with an average wind speed of 

3 m/s. however, since the energy available in wind varies 

as the third power of wind speed, the power produced at 

such velocities would be lower than conventional wind 

turbines under higher speed winds. 

The rotating turbine shaft is supported by magnetic 

levitation instead of ball bearings. Magnetic bearings have 

been used for smaller turbines and pumps, but they 

generally can't handle impacts disturbing the shaft, and 

generally require actively controlled electromagnets. 

Making magnetic bearings strong enough to handle the 

loads of a wind turbine would use prohibitive amounts of 

power just keeping the electromagnets running. The 

Chinese design is said to use permanent magnets to 

support the rotor shaft.

Now-a-days due to increase in population there is increase 

in number of vehicles which leads to increase in 

consumption of fuel, so there is crisis of depletion of fuels. 

This fuel-less-car is invented for this purpose. 

In fuel-less-car dynamos are connected to the wheels of 

the car which are here used as power generator. Two set of 

two batteries are taken. In which one of them is charged. 

One set is connected to rear wheels and another set is 

connected to front wheel. From one charged battery of set 

car will run and will charge the uncharged battery. When 

first battery is discharged, the another battery will be 

charged as voltage is developed across the two terminals 

of the dynamos due to electromagnetic induction. 

In this model engines and source of fuels are replaced by 

dynamos and charging batteries. As this car is made fuelless, 

it can surely be used as excellent means of 

transportation. 

Due to this model danger of Global Warming is reduced 

and hence it is eco-friendly.

OIL SKIMMER 

Each and every type of the pollution is very significant 

according to the view point of the conservation of the 

Biodiversity. 

But, we have selected this topic (Oil Spill & its control) at 

the background of the last year's ship-wreck of the “M.V. 

Chitra” and “Khalijia”. 

The spilt-over oil spreads rapidly to the all direction. That 

led into the destruction of the sea-birds, fisher, turtles and 

other aquatic animals. 

Here, the two big issues arise viz, 

1) How to get the hold over the spreading oil, and 

2) How to collect it quickly, 

It is very difficult to control the spreading oil, but not the 

impossible one. 

The immediate oil collection will result in the flawless oillogistics 

and the healthy marine ecosystem. 

At this critical point, our model works as the “helpinghand” 

for the recovery of the marine-life and the Oil 

business world as well. 

So, here, we dare to suggest a model under the guidance of 

the experts for the collection of the superficial oil layer 

floating over the salty water. 

We are sure that, it will work successfully at the true level.

HOME MADE LASER-BASED 

LIQUID PRISM SUCROSE 

METER 

In this experiment, a sucrosemeter was constructed using 

a diode laser pointer and a hollow equilateral glass prism. 

Sugar solutions in water having different sugar 

concentrations were placed in the hollow glass prism and 

diffraction of a laser beam through these solutions were 

measured as a function of sugar concentration. The 

refractive index of the sugar solutions having different 

sugar concentrations was calculated using the refraction 

data and parameters of prism – angle of prism, angle of 

minimum deviation. 

The refractive index was calculated using the formula 

where n is the refractive index; 

θ is the angle of prism and 

P 

θ is the angle of minimum deviation. 

d 

2012 

The hypothesis of this experimental investigation was that 

the refractive index of the sugar solution in water would 

increase as the sugar content in the solution increases and 

that the increase would be linear. It is also anticipated that 

the sugar concentration of an unknown solution (e.g. 

squash, soft drinks) can be determined using this 

sucrosemeter.

HYDROGEN PRODUCTION 

AND ITS APPLICATION 

Working Principle 1. Electrolysis of Water: When an 

electric power source is connected to two electrodes 

dipped in an electrolyte solution of H2SO 4 in water, 

hydrogen will appear at the cathode (the negatively 

charged electrode) and oxygen will appear at the anode. 

1. Bio hydrogen production from algae : The deprivation 

of sulphur in Chlamydomonas reinhardtii facilitates the 

natural production of hydrogen during photosynthesis. 

This takes place with the help of hydrogenase enzyme 

which catalyses the following reaction: 

+ reduced 

(2H + 2X à 6 H 2 + 2X oxidized) 

Where, the electron carrier, X is ferredoxin 

Applications : 1. The hydrogen produced is taken to a 

storage tank where hydrogen is stored safely in order to 

prevent escape into the atmosphere. 

2. It is further transported through well insulated 

pipelines to a power house generator where it is used in 

hydrogen-oxygen fuel cells to generate electricity. The 

oxygen for this purpose is sourced from the same 

electrolytic process for the production of hydrogen. 

3. It is also used in hydrogen fuelled space rockets as well 

as automobiles which work by converting the chemical 

energy of hydrogen into mechanical energy by burning it 

in internal combustion engines or by reacting it with 

oxygen in fuel cells to run electric motors.

“ONTHOKPA LOO” 

(NEW FISH TRAPPING 

DEVICE) 

Introduction: 'Loo', is an indigenous device of Manipur which is 

widely used to trap fishes In the lakes , drains, paddy fields 

etc.Where there is current water. 

But the traditional 'Loo' takes more time to catch fishes since it 

has only one entrance. Equipping the fisherman with an 

improved fish trapping device called 'ONTHOKPA LOO', which 

is modified from the traditional one. Using such model, one will 

have a significant role for sustaining in their fishing profession 

and will improve the overall socio-economic condition in rural 

areas and the state as a whole With this aim and object, 

Onthokpa Loo' an important device for fisherman has been 

designed and dedicated to the fisherman community of the 

nation. 

Scientific Principle Involved : Uni-directional Valve. 

Material Required: i) Bamboo, ii) Binding Wire, 

iii) Binding Plastic. 

Construction and Working 'ONTHOKPA LOO' : In my model 

'Onthokpa Loo', bamboos are cut off at a height of 3ft according 

to the height of the model Again cut the bamboo pieces in 

lengthwise to make Payas (twig of bamboos) in around 2mm 

diameter and some are at 3mm diameter. 

By collecting about 160 pieces of Payas of 2mm diameter 

are arranged in a right cylinder from and begin to make its 

shapes fixing on a circular ring (of Paya) about 7 inches of 

diameter. The payas are binded spirally using the binding wire 

and plastic to become its exact figures. The two ended sides are 

in the form of a dome and hollow shaped respectively. We fixed 

the 5(five) different valves (Shou) in different directions of 

'ONTHOKPA LOO'. 

As fishes are of different kinds, their movements are also 

different. Some fishes like to move towards the direction of 

water current, some fishes like to move opposite to the directions 

of water current and mud fish, Lata fish (Ngamu) Which are 

frequently jumped when their ways are obstructed by some 

materials. To enable to catch such all fishes simultaneously

HAND MADE PAPER FROM WASTE 

MATERIALS LIKE BETEL NUT 

COVER AND BANANA TRUNK 

Scientific Principle : Any cellular materials like bamboo, hardwood, 

cotton rags, wheat straw, rice straw, sorghum, stalks hemp, jute etc 

are possible raw materials which could be used for paper and board. 

The acidic substance present in such material makes the paper 

brittle which can be removed by adding Na OH/Ca(OH)2/KOH, to 

loosen ligno-cellulosic bond. 

Materials required:- 1.Betel nut cover (Tamul cover), 2.Banana 

Trunk, 3.Vessel for boiling 4.Stove, 5.A tub, 6.Stick/wood for beating, 

7. Hollow wooden frame of different size, 8. Mesh, 9. Cloth, 10. 

Squeezing machine, 11. Calendaring machine. 

Processes: Tamul cover or Banana trunk is cut into pieces 

approximately 2cm. to reduce the acidic substance in these 

materials. NaOH/Ca(OH)2/KOH is added to loosen the ligno 

cellulosic bond. Sufficient water is added and the whole thing is 

boiled for about 30 minutes. Then to remove black liquid of Na/K/Ca 

lignite and unused alkalis, they are washed by using sufficient cold 

water. The boiled materials are kept for wet beating in a tub. A mesh 

tray is kept in the tub. A hollow wooden frame is kept on the mesh 

tray with sufficient water in the tub. A pulp mixture with water is 

poured on the mesh frame to get the required thickness of paper. The 

mixture spreads uniformly on the mesh tray and then the formation 

is taken out carefully and kept for a while under a cloth. 

Few pieces of clothes having paper layers are kept in a squeezing 

machine for removing water. The paper so obtained is dried for a 

while under sunlight and the paper is then separated from the cloth. 

The paper is then made smooth by a calendaring machine. 

Application/Uses: These types of hand made paper/board can be 

used in making the following:i) 

Carry bags, ii) Greeting cards, iii) Envelopes, iv) Visiting cards 

v) Wedding cards, vi) Letter heads, vii) Wrapping papers, 

viii) Canvas for painting, ix) Hard cover paper, x) Display board, 

xi) Partition wall etc. 

Conclusion: It is generally long lasting and does not get spoiled 

easily. Old books can be saved by pasting this paper to the torn out 

pages. Board can also be used for partition of walls and display 

board/notice board etc.

TRADITIONAL KNOWLEDGE 

OF HERBAL REMEDIES AMONG 

THE KHASIS OF MEGHALAYA 

Introduction: Meghalaya is situated in the North – Eastern 

India is an upland landmass bound by seven Districts 

surrounded within by different tribes. The population is 

predominantly rural, with 81.41% of the population belongs 

merely to the scheduled tribes. The local people are very much 

closely associated with nature, and with their knowledge about 

the plants available around them, they can easily avert and 

cure themselves from several disease and complications. In 

this project, the information regarding the traditional method 

of utilization of few plant species that are used to treat various 

ailments are enlisted briefly. 

Methodology : A survey was done in few places in 

Kyrdemkulai, Ri – Bhoi District, and some interactions with 

few traditional healer (nong ai dawai kynbad) in and around 

the area yield a vast knowledge of herbal remedies for 

treatment of various diseases. Information on the traditional 

medicine used of plants was collected by direct field 

interviews. 

Result: The medicine plant recorded during the survey is listed 

below by Botanical names, Local/Vernacular name, Habitat and 

uses. 

1.Botanical Name: Toddalia aciatica. 

2.Botanical Name: Equisetum 

3.Botanical Name: Cuscuta reflexa 

4.Botanical Name: Solanum Indicum 

5.Botanical Name: Terminalia chebula. 

6.Botanical Name: Viburnum foetidum. 

7.Botanical Name: Acorus calamus. 

8.Botanical Name: Adhatoda Vasic. 

9.Botanical Name: Zanthoxylum acanthapodium. 

Conclusion: Traditional health – care system is an age–old 

practice performed since ancient time by the people in the 

state of Meghalaya and were used by the local people to 

overcome the different complications.

The common components of a rainwater harvesting 

system are: 

Catchment: Rooftops are the best among them because of 

the large coefficient of run off generated from them and 

there are less chances of contamination of water. 

Conveyance: Conveyance system basically includes rain 

gutters and down pipes which collects the rain water from 

catchment to the storage tank. 

Storage: Tanks should be covered to prevent mosquito 

breeding, evaporation losses contamination and algal 

growth. Leakage from tanks should be prevented. 

Filter: A simple filter of gravel, sand and charcoal can be 

made all of which are easily available. 

Purification: Use Chlorine or UV light to purify the 

collected rainwater for potable use. 

Distribution: Before supplying for human consumption 

the water should be filtered purified and kept in a PVC 

tank connected to a tap for withdrawal. 

Recharge structures: Rainwater may be charged into the 

groundwater aquifers through dug wells, bore wells, 

recharge trenches and recharge pits. 

Benefits of Rainwater Harvesting: Rainwater harvesting 

increases water security. It is the perfect solution to meet 

water requirements especially in the areas which do not 

have sufficient water resources.

ZERO ENERGY 

COOL CHAMBERS 

Materials: - For construction this, no experts are required, moreover 

this chamber require only ordinary materials like bricks, sand, 

bamboo, sack etc. This can be made on the earth. High level land 

(place) is required where there is plenty of breezes available. There 

should be roof above this cool chamber, which will prevent rain and 

sun. Therefore, it should be made under an open shed. 

Construction: - The rectangular chamber is made of two wall bricks. 

7.5cm should be left between walls. This portion should be filled with 

river sand. Before making the walls the bottom part of the chamber 

should be leveled with sand and closely packed with one line bricks. 

Bricks should be higher in size and they should be wet with water 

before the construction. The length, breadth and height of the 

chamber should be 165cm x 115cm x 67.5cm. The brick should be 

joined with clay so that blocks should not fall down. Use of cement 

should be avoided. The lid of the chamber should be made of thick 

sacks with bamboo frames. 

Working in this cool chamber is very simple. Before keeping 

vegetables and fruits, the chamber should be cooled and cleaned with 

bleaching powder or chlorine water. To cool the chamber the sand 

between the brick walls should be wet with water. Water should be 

poured very slowly. The temperature should be kept below the 

surroundings. Wetting of sand should be done twice daily. Vegetable 

can be kept fresh for 4 to 8 days. No water drops should be allowed to 

fall on the vegetable. For that polythene can be kept over the 

vegetables containers. Since water is poured into sand in between two 

walls of bricks, there are pores in bricks which allow water to 

percolate to the outer surface where evaporation of water takes place 

producing a cooling effect in the chamber. 

Advantages 

· Alternative of Refrigerator and cold storage · Low cost materials 

are required · No electricity is required · No experts are required 

· Pollution free · Materials are eco – friendly · Better 

marketability of fresh horticulture produces that ambient · Retain 

nutritive value. 

Areas of application 

· Short term storage of fresh vegetables, fruits and flowers 

· Growing of white button mushroom · Ripening of tomato and 

banana · Plant propagation · Storage of processed fruit products.

EARTHQUAKE PROOF BUILDING 

Principle of Earthquake Proof Building: - The principle we use 

here in based on the first law of Newton's first law of motion 

which state's that a body at rest will remain at rest and body in 

motion will always be in motion so long as no external force occur 

to change that state. Now in our project we are concerned with the 

first part of the law only i.e the body at rest will remain at rest if 

there is no external forces' acting on it. 

If we are able to keep our building at rest by some means then we 

can achieve our objective. 

Principle of Construction: - First of all we need two metallic 

chassis of same size one above the other. Between this chassis 

there are several concave trays facing one another one from the top 

and one from the bottom. Between this concave trays we sand 

witch a metallic spherical shells. These sets of balls and trays are 

placed and bolted along the entire length and breadth of the 

chassis and along the cross members of the chassis. 

This sets of ball trays can be replaced as and when required. Sir, 

this idea can be applied for the construction of few storey's 

building only. 

Working Principle of E.P.B: - During earthquake the lower chassis 

shares the motion of the ground and just rolls under the balls 

while the upper chassis remain more or less at most obeying 

Newton's law of Inertia. 

Further more to enhance the stability of the building we attached 

four gyros one on automatically using electric motors and 

electronic device. As the materials are not avoidable they are not 

used here. 

This simple idea can be used for the construction of nuclear power 

station and other dangerous installation. 

Explanation About Model: - Here we used glass marble as metal 

balls and teaspoons as metal concave trays. These chassis are 

made of wood and also the rest of the building. 

When the under sides chassis in proved and pulled rapidly, the 

upper chassis and the building just remain more or less at rest and 

ensuring safety. 

This simple and novel ideal solution if adopted and implemented 

will save a lot of lives and properties.

ELECTRONIC WASTE 

RECYCLING 

(TRANSISTOR AS A PHOTOCELL) 

This project is about the use of transistor 2N3055 as a photocell. 

The transistor can be a bad transistor which is no longer useable 

for its normal application. This project gives us new technology 

of recycling electronic waste. It is easily available and 

inexpensive. This project is all about benefiting the people 

where there is very limited or no power supply. It can be used 

any where provided that there is a good sunshine. Transistor 

2N3055 is an npn-transistor which can be used as a photocell 

when cut open. A photocell is a device which convert light into 

electrical energy. A single photocell produces a very small 

amount of voltage, so, a number of photocells are connected 

together to form a panel of cells. This panel of cells can be used 

for charging mobile phones, batteries operating LED lights etc. 

Used transistors 2N3055, circuit board suitable resistor, 

connecting wires, soldering equipment, LED lights, multi-meter 

are used in this project. 

The transistor 2N3055 is cut open using a hacksaw blade to act 

as a photocell so that the transistor itself is exposed to sunlight. 

The voltage produced is collected from the base and the emitter 

of the transistor, and the collector is kept open. The range of the 

voltage ratings for each transistor as a photocell is 0.3V to 0.5V. 

Since LED operates at a voltage range of 2V, ten such photocells 

connected in series can give 3V to 10V supply which is 

connected in series with a suitable resistor can be used to light 

one LED light or charge a battery of voltage rating which is in the 

range. 

It can be used any place where there is sunlight. It can be used 

for charging mobile phones during sunlight when there is no 

power supply. It can be used for charging batteries.

GREYWATER RECYCLE 

SYSTEM 

Greywater is commonly defined as wastewater generated 

from bathroom, laundry and kitchen. This system 

provides technique for reuse of for greywater in 

residential complexes and other habitations. 

The greywater recycle system has the following 

components: 

1. Screen: Screen is kept at the outlet of pipes collecting 

greywater from different sources which remove large 

suspended particles. 

2. Sedimentation tank : This component separate solids 

and remove bad odour from greywater. Grey water is fed 

to the tank and detained it for a period of an hour or two 

whereby the solids are settled at the bottom. 

3. Horizontal roughing filter: The horizontal flow 

prefiltration technique using coarse gravel or crushed 

stone as a filter media is also a sound alternative in 

handling turbid waters. When raw water flows through it, 

a combination of filtration and gravity settling takes place 

which reduces the concentration of suspended solids. 

4. Slow Sand filter : Slow sand filter is used to remove 

suspended inorganic or organic matter and also pathogens. 

It consists of fine grain of sands on the top of gravel. 

These sands at the top develop a gelatinous matter or bio 

film which traps and destroys the pathogen. 

Once, the grey water is treated by the above methods, it 

can be safely used for various purposes namely, toilet 

flushing, cleaning purposes, irrigation, building 

maintenance etc. In this way, waste water can be recycled 

which helps in conserving precious water, preventing 

water pollution.

ROOF TOP RAIN 


Roof-top rain water harvesting is the process for 

collecting and storing rain water falling on our roof tops. It 

is a special case of Rain Water Harvesting in which rain 

water is collected and stored in a scientific and controlled 

manner for future use. 

In Roof top Rain Water Harvesting, the rain water that falls 

on the rooftop is collected and stored in underground 

tanks. Here, the roof top is the catchment. Apart from roof 

tops, even footpaths and roads can act as the catchment as 

these areas too receive direct rainfall. 

The rain gutters and down pipes acts as a conveyance 

which collect rain water from catchment to storage tank. 

The storage system is the most important post of rain 

water harvesting. It is designed according to the amount of 

water that is to be stored. Its structure may vary from 

permanent masonry tanks, ferro – cement tanks to plastic 

or metal tanks. The water thus stored is then pumped and 

channeled through pipes for household use. 

Rain water collected on the roof is very pure and clean. 

However, there are many substances which gets mixed up 

with this pure water on the roof. They may be leaves, 

dust, bird-droppings, etc. These contaminate needs to be 

filtered before the rain water in stored. There are many 

filtration systems – Sand bed filter, pop-up filter and 

stabilisation. 

Rain water harvesting has several benefits. It increases 

water security and a perfect solution to meet water 

requirements, especially in the areas which do not have 

many water resources. It helps in improving the quality of 

the ground water and also increases the level of the 

ground water. It also helps in improving overall floral 

system. It reduces the loss of top layer of the soil.

The present indigenous water hand pump has several 

advantages over the traditional water hand pump. The 

water hand pump need to be purchased from market 

with reasonable high cost whereas the indigenous water 

hand pump can be easily assembled with low cost 

materials. 

This system aims to reduce electric power consumption. It 

is based on the principle of atmospheric pressure. 

The material required to assemble an indigenous water 

hand pump are rubber, rope, plastic pipe, Pipe holder, 

Valve, L-bend, T- Join, Tap. 

The indigenous water hand pump is fitted inside the well 

and a rope with rubber is placed inside the pipe. When 

the rope is pulled, vacuum is created and water can be 

lifted up to 30 ft. In this way water can be lifted from well 

to storage tank. 

The indigenous water hand pump is very useful in rural 

area to lift water from a well or even water stored at low 

land.

ELECTRONIC WATER 

LEVEL INDICATOR 

This project consists of 6 Volt Transformer, Resistors-2.2 k ohms 

and 22 K ohms, LED's, Alluminium wire of desired length, 

Cardboard box or Plastic box, Printed circuit board, and Low 

voltage NPN Transistors. 

In this system, one electrode Probe of 6 volt is placed at the 

bottom of the tank. Next Probes are placed step by step above the 

bottom Probe according to the desire of the user, say 1 foot, 1 

metre apart etc.When we pump water in side the tank, the 

raising water gets electrical connection to the 6 volt Probe 

through the water and the corresponding Probe, which in turn 

makes the transistor conduct to glow the LED light and indicates 

the level of water in the tank. The ends of the Probes are 

connected to the corresponding points in the circuit as shown in 

the diagram: 

When the level of water rises in the tank, and comes in contact 

with the Probe 1, it gets electrical connection with the 6 volt 

Probe at the bottom of the tank, which in turn lights up the LED 

1 at the indicator board, and so on. The distance between the 

Probes can be placed as desired. 

Last, as the water rises in the maximum and comes in contact 

with the last Probe or Probe No.3, the LED 3 lights up, and also 

the buzzer gives off sound which tells us that the tank is full as it 

is time to turn off the pump. 

This project aims to eliminate over pumping of water to 

overhead tanks. We can also monitor the amount of water in the 

tank by simply switching on the system and no need to peep into 

the tank anymore.

AREA OF A CIRCLE 

AND CONE 

The area under the perimeter of the circle is known as 

area of circle. Area of circle can be found with the help of 

this model. In this model the area of circle is divided into 

eight pieces of coloured plastic pieces. When these pieces 

are arranged in linear way in opposite direction they form 

a rectangle. Circumference of a circle become length of the 

rectangle and radius of the circle become breadth. 

Area of rectangle = length × breadth 

= πr × r 

= πr2 (Which is the area of circle) 

Simply we can explain the area of cone in similar way, in 

which the surface area of cone is given as below: 

Area of rectangle = length × breadth

Satellite is a heavenly body that revolves around the earth 

surface. Geo stationery satellite is a satellite that revolves 

around the surface with speed equal to earth rotation. 

Thus it appears to be motionless and remains at a fixed 

position in the sky as seen by the observers on the ground. 

In this model, we have shown three satellites at an angle 

of 120 degree of longitude and provide coverage to whole 

(95%) planet. 

Materials Used: 

1. Iron Stand 

2. waste by-cycle rim 

3. 9 volt battery 

4. One motor 

5. 3 plastic balls 

6. wooden sticks 

7. Bowl shaped iron sheet 

8. decoration material 

Construction and working: 

Fix cycle iron rim on a iron stand. Place a round bowl 

shaped iron sheet on the cycle rim and attach it firmly. Fix 

three iron rods on the sides of cycle rim at a angle of 120 

degree each. Now attach a 9 volt battery with motor and 

fix a cotton thread around the wheel and motor. Fix three 

plastic balls at the tip of the rods. 

When motor is switched on the rim rotates along 

with three balls fitted at the tips of rods. The speed of the 

balls and the iron sheet are same. Iron sheet represents the 

earth surface and plastic balls represents geo stationery 

satellites.

OF NUCLEAR POWER PLANT 

What is Nuclear Power Plant? 

It is the plant where with the help of nuclear reactor 

sustained nuclear chains reactions is carried out for 

generating electricity and for the propulsion of ships. 

Usually heat from nuclear fission is passed to a working 

fluid which runs through turbines that power generators. 

Threats to nucler power plant 

1. Earthquake 

2. Tsunami 

3. Over heating 

4. Failure in continuous supply of coolant. 

About the Project 

We are aware that there are different techniques for the 

generation of electrical energy, interalia including thermal 

power generation station .nuclear power station, wind 

mill, solar cell etc. But amongst them the nuclear plants 

are usually considered to be the base load stations which 

are best suited to constant power output. Being the best 

source of electrical energy, it requires utmost safety and 

protection. As an iota of lapse in its security during its 

functioning would leads to destruction and devastation. 

Till now 57 accidents have taken place since the 

Chernobyl disaster in 1986.keeping this in view, a few 

innovative ideas have been attempted in my above said 

project to ensure safe functioning of the nuclear plant.

Introduction: The project is made on mitotic cell division 

in plant and animal cell. 

Scientific Principle: The mitosis cell division which 

perform the function of dividing cells in animals and 

plants. 

Material Used: Wooden ply sheet, thermocol sheets, 

plastic pipes, white cellotape, coloured tapes, fevicol, 

chart, markers, PVC pipes, ribbons, Large wooden block, 

copper wires, pins etc. 

Construction of project: Large sized ply boards and 

thermocol sheets are joined to make two large rectangular 

boxes on which all the phases of mitotic cell division are 

displayed. In the upper part of the project mitotic cell 

division in animal cell is shown. It takes place in different 

phases like Interphase, prophase, metaphase. Telophase, 

anaphase and cytokinesis. In animal cell, spindle 

formation is amphiastral due to presence of asters. The 

process of cytokinesis is amphiastral due to presence of 

asters. The process of cytokinesis is centripetal in a 

animal cell. In the lower portion of the project there is 

mitotic cell division in plant cell. The whole process of 

cell division is same except some distinction i.e. 

centrosome is absent, so no asters are formed and spindle 

is anasteral. Spindle cytokinesis is centrifigual. 

Significance: The mitotic cell place an important role. It 

performs different functions like 1. Maintenance of 

chromosome number. 2. Maintenance of cell size. 3. 

Growth. 4. Cell replacement. 5. Regeneration. 6 Repair etc.

MOBILE OPERATED 

WIRELESS SWITCH 

Now–a–days, we see many switches around us. These may include 

the simple ones like Toggle Switches to the complex ones like the 

retina scanning electricity operator. The Mobile Operated Wireless 

Switch is also one of those. But it has a great exception which 

separates it from others; and it is that it can be operated from any 

distance. 

This switch can operate any electrical device connected to it just by 

receiving a call from the user's phone. The user can operate any 

device, from any distance, for any duration. 

All of these are advantages of this switch which make it very 

beneficial operation of anything from any corner of the world will 

surely make it beneficial. 

Using this switch, a farmer would be able to irrigate his fields in 

other state or even other country. 

A business-man can perform multi task in his factory by operating 

his machines with a phone. This reduces cost and human labour, 

thus increasing the efficiency and reliability of the work. A person's 

mobile phone becomes a wireless controller and then switches the 

device in a fraction of seconds. 

The idea of this amazing switch emerged from the fact that mobiles 

work everywhere and connect people over vast distances. And if the 

user could connect to a machine in such a way it would be really 

amazing; and this is what the switch really does. Moreover, most of 

the wireless switches work from a limited distance which is not a 

characteristic of this switch. This switch can be modified and 

mechanized according to the user's choice. 

Now, 3G technology is becoming popular day by day. Usage of this 

technology in the circuit will make it completely revolutionary. This 

will help the user to see the live images of his work through mobile. 

A small additional circuitry will also enable the user to see the live 

temperature of a particular area, on his mobile. 

Information about anything in fields like soil conditions, weather 

conditions and intensity of the sunlight would enable a farmer to 

know better about his fields and take decisions correctly. Thus, 

reliability increases as compared to the human labor. 

Thus the usage of this technology i.e. The Mobile Operated Wireless 

Switch in future will make our lives more comfortable and 

innovative in terms of daily usage.

Introduction: This is a magnetic chain reaction to launch 

a steel ball at the target at high speed. 

Principle: The project is based upon the conversion of 

magnetic energy into kinetic energy and the concept of 

one dimensional elastic collision. 

Idea Capturization: I got this idea from Discovery 

Channel. 

Material Required: i) Neodymium Magnets: - It is an 

alloy of Neodymium, Iron and Boron. Its chemical formula 

is Nd2 Fe14 B. It was firstly introduced by General Motors 

in 1982. 

ii) Steel Bearing Balls: - These balls are used as bullets 

for the gun. The size and mass of all should be same to 

fulfill the condition of one dimensional elastic Collision 

iii) Wooden Channel: - a wooden channel is required for 

free movement of the steel balls. 

Working: When we release first ball, it is then attracted to 

first magnet. It hits the magnet with respectable amount of 

force, and a kinetic energy we will call “1unit”. The 

kinetic energy of the ball is transferred to magnet and then 

to the ball that is touching it on the right and then to the 

ball that is touching to it. The third ball is now moving 

with kinetic energy of “1unit”. But it is now moving 

towards second magnet. It picks up speed as the second 

magnet pulls it. So when it's the second magnet then its 

kinetic energy become “2unit”.This process goes on and at 

the last, the last ball get sufficiently high energy due series 

of magnets. 

Where concept can be used : The same idea could be used 

to make such type of guns in more advanced version.

CARBON COROUSEL 

Global warming is a reality. Innovation in energy, 

technology and policy is sorely required to prevent the 

earth atmosphere from becoming a hot house. 

The displayed project is just one of ways to wash out CO 

2 

from atmosphere by using filters made of wet or dry 

sorbents to absorb CO as the air wafts through them. 

2 

Filters of size 2.5 m and 1 m wide approximately are used 

having fibres coated by negatively charged CO -2 irons 

3 

and sorbents like NaOH which absorbs CO . 

2 

2NaOH + CO Na CO + H O 

2 2 3 2 

Na CO + CO + H O 2NaHCO 

2 3 2 2 3 

The filter loaded with NaHCO 3 is then lowered into an 

evacuated chamber and washed with a fine jet of water in 

the form of mist to get back CO 2 and Na2CO 3. The CO 2 thus 

obtained in the evacuated chamber is compressed and 

utilized for various purposes. 

Advantages : 

1. Ten million such carousels round the globe are 

effective enough to prevent global warming. 

2. The cost of operating such machines is compensated by 

selling CO to :- 

2 

(a) Chicken and meat industry as freezing agent. 

(b) Beverage Industry for carbonations of soft drinks. 

(c) To industries that use carbonate such as glass and 

cement industries. 

(d) To algae farms for production of ethanol.

so that rain water collected here can be used for various 

purposes. 

2. Open Well: One pipe is sent to the open well near the 

house. The water gets stored in the open well to increase 

the underground water level. 

3. Bore Well: It is an artificial well constructed near the 

house. It works as the storage tank. 

4. Trench: The trench is constructed along the boundary 

of the house can also be used for this purpose. 

5. Sand Filter: It is used to purify water. It is to be kept 

underground. It has layers of mesh, gravel, coarse sand, 

etc. 

6. Storage Tank: The water purified from sand filter can 

be stored in the storage tank which is also kept 

underground. A motor is fitted to pump the water. 

7. New Conventional Water Purifier: This can be used to 

purify rainwater. Pine tree bark, grid, etc. can be used for 

this purpose.

AUTOMATIC DOOR LIGHT 

AND AUDIO SYSTEM 

The model in question is of a system which can be 

installed at the entry point of any house/shop or any other 

establishment. It has a usual door-bell and a switch. When 

the visitor presses the door-bell-switch, the door-light gets 

turned on. It is accompanied by the audio system getting 

turned on. As a result the person sitting inside can talk to 

the visitor(standing outside) from the comfort of his/her 

room. 

This system may be of special use in cases of: 

—Patients 

—Severely disabled persons 

—Severe Cold Seasons 

—During the environment of insecurity. 

—House occupants being busy when a 'wrong' visitor 

knocks. 

The door-light and door-bell get turned on only for a 

limited period (after the door-bell-switch's pressed). The 

door-light does not glow during day. So there is no 

wastage of electricity. 

Construction (Summary): 

The system has, besides usual door-bell/light, switches 

etc., some transformers(for stepping-up/down electricity), 

Rectifiers(consisting of 4 diodes) to change AC to Splitting 

DC, Condensor(for filtering split DC), IC, Some relays, 

LDR, Capacitor, Audio amplifier, Speakers, Micprophones, 

etc. 

With a little addition, this system can also be used to have 

a two-way video talk with the visitor.

As the population of the world is increasing, natural 

resources such as land and water are becoming scarce day 

by day. Traditional farming will not be able to feed the 

world in the future. Farmscrapers will help us to grow 

more food in a limited space with reuse of precious water. 

Farmscraper is a multi storeyed building in which plants 

are grown with the help of hydroponics i.e. plants are 

grown without soil. Plants are grown with the water 

obtained by cleaning sewerage water. The treated water is 

collected in a tank to which required fertilizers are mixed 

and is then supplied to the various storeys of plants. The 

required water is absorbed by plant roots and the extra 

water is reused. Thus a large amount of water is saved. 

These farmscrapers will have many advantages such as 

more yields of crops from less space. Use of insecticides is 

much less as plants are grown in a closed environment. As 

the farmscraper is a huge building located close to a city 

and can grow all the crops required for the city, 

transportation costs are lesser. So the farmscraper that we 

have shown in this project is a model of our future high 

tech farms.

ECO FORESTRY 

Brief Summary : This exhibit has been designed to show 

various practices which must be followed to sustain and 

conserve the bio-diversity of the forests. Which will in 

return help to improve the environment of the EARTH. 

Explanation 

The practice of Eco forestry is based on ecological 

principles. Eco foresters seek to understand and work with 

the complex processes and patterns of forests to maintain 

native diversity, while harvesting forest goods and 

products on a long-term sustainable basis. By maintaining 

a multi-species, multi-aged forest, the structural and 

genetic richness and diversity of the forest is sustained 

and allowed to continue to evolve through its natural 

processes and patterns. Attention is paid to sustaining 

healthy soils, water quality and flow, and habitat for 

wildlife. The practice of Eco forestry relies primarily on 

selective logging and harvesting of forest goods and 

products. Eco forestry has many principles within the 

existence of itself. It covers sustainable development and 

the fair harvesting of the organisms living within the 

forest ecosystem. There have been many proposals of 

principles outlined for eco forestry. These principles are in 

the form of forest practices which we should follow to 

maintain the Bio-diversity of the forest and alongside 

harvesting it sustain ably for our use. 

Some of the main Practices are : 

Retention of Trees, 

Developing Riparian Zones and 

Timber extraction Zones, 

Developing watersheds, 

Ecological succession, 

Natural regeneration, 

Prevent Forest fires, and Protecting wildlife.

Introduction: This zero pollution project aims at 

converting waste plastic garbage into value added fuel viz 

diesel. Waste plastic problem is an ever increasing menace 

for global environment. So to end this menace the project 

on 'Diesel made from Waste Plastic' is made to dispose 

waste plastic material and thereby converting it into 

hydrocarbons i.e. fuel like diesel. As in the project, the 

conversion process ensure no release in CO 2 into air or 

hazardous pollutants. 

Working: In this model, the waste plastic 

(thermosetting/thermal plastic) to convert it into diesel. 

Then the plastic is crushed and compressed to remove the 

air from it and then the plastic is transferred into PDU 

(Plastic Depolarising Unit). Then in PDU calcination 

process there is a release of Hydrocarbon gases. Heavy 

gases are in the range of C to C and lighter gases are C 

18 24 9 

to C . The gases are transferred to the bubbler where they 

18 

form separate layer over that which can be separated with 

the help of separating funnel. In reservoir gases are 

condensed Heavy gases are directly pass through the 

condenser and then the condensed hydrocarbon gases are 

collected in the collector to make it the pure form of 

diesel. Finally we do the Distillation Process and the end 

product is the Diesel. 

Advantages: About 40 lakh tones of plastic waste can be 

converted into 4 x 1012 ml of diesel. This project is really 

cost effective as only Rs. 17 cost for 1 litre. Govt. is also 

providing 30% subsidy on this industry. This type of 

diesel can be used in vehicles, gasoline engines, iron 

furnaces etc.

CHEAP AND HOME MADE 


Solar energy is the renewable resource of energy. Every 

action in this universe needs energy. So demand of energy 

is increasing day-by-day. If we continuously go on using 

non-renewable sources of energy, the day will come that 

we shall have no source energy to run our vehicles, 

factories and to light up our houses. Now time has come 

we should think about use of renewable sources of energy. 

In winter we use a lot of electric energy and gas energy to 

warm up water for domestic and commercial use, which is 

very costly besides this we are stepping towards finishing 

non-renewable sources of energy. 

My Model: In my model cheap and recyclable material to 

heat water for domestic and commercial use everyone can 

make it at home himself. Main principle used in this 

project is Green House Effect in place of copper 

aluminium pipe used to make it cheap empty plastic 

bottles and plastic sheet is used to produce double Green 

House Effect. Thin aluminium is used to reflect sun rays 

which fall on it. Plastic bottles do not allow reflected sun 

rays to escape from the system and temperature is 

increased. Temperature of water may be up to 65 to 70°C. 

This is the best use of solar energy. We should make 

people aware about it.

In the model design of self sustained residential premises 

all most all the organic waste may be it is from the kitchen 

or sewerage Water has been put to use and waste water 

has been put to recycle. Added the potential energy spent 

to pump, the water has been harnessed from to down 

word floor from floor to floor and used to mechanically 

run the fans at each floor and cool the building centrally. 

This model thus acts as a role model for self sustained 

residential premises. 

The organic waste of the housing complex will be 

microbially treated to extract gas for fuel and left over 

organic matter to be used at manure the sludge left is 

treated with reed beds thus converting it into semi solid 

useful bed for growing plants and getting fuel thus making 

the environment clean and green. 

The roof tops have been used for harnessing solar energy 

and rain water which after utilizing its potential energy for 

running fans will be put in a recharge well to recharge the 

ground water thus helping upliftment of the declining 

water table . 

Advantages:- 1. As energy needs are increasing everyday 

so harnessing energy is a boom to tide over the energy 

crises.

MODERN CHECK POST 

In this model, we have made a check post on wooden 

road. There are two gates G1 and G2 on this road. The gate 

G1 remains open where as the Gate G2 is kept closed by 

the security persons. In front of the Gate G2,there is a pit 

under the road. Here the road is like a roof covering the pit 

and this roof is placed on the pit with the help of iron 

levers. When a vehicle comes it stops at the gate G2 and is 

checked by the security persons. If any anti-social element 

tries to break the barrier the strike of fast-moving vehicle 

will rotate the barrier rod to one side which will operate a 

switch due to this electro magnet will attract the iron lever 

on which the road is placed, the road will fall down and a 

pit will form in front of gate G2. The vehicle of anti-social 

elements will trap in this pit and they will be caught by 

the security persons. But on the other hand there will be 

alarming and red light signal at gate G1 and a 12 volt DC 

motor will close the Gate G1 to prevent ordinary traffic to 

trap in the pit.

This project is about using still pond water in villages. In 

this project, we have used magnets which are attached 

with balls in pond, when pond water show movement due 

to air currents the magnets attached to balls move up & 

down in solenoid (copper coil) like arrangement due to 

which deflection appears in the indication meter. Strength 

of current can be increased with power of air currents of 

powerful magnets to be used in pond water. 

Being a resident of holy city Amritsar, this concept can be 

applied for small electricity needs of Sarovar of Sri 

Harmandir Sahib as we know that filters are installed for 

filteration of water of Sarovar due to which a lot of 

disturbance is produced in water and same above working 

of model can be induced for electricity production. 

This Concept of electromagnetism is presently used in 

P.A.U. Ludhiana in Pisciculture (Fishery) center for small 

needs of electricity. 

Apparatus Used: 

Glass Chamber modified as Aquarium, Iron rods, Copper 

Coil, Indication Metre, Four Plastic Balls.

AUTO GODOWN 

Introduction: In India, about 53 % population is connected with 

agriculture directly or indirectly. There is shortage of labour in 

India. Due to shortest of labour most of the food grains goes 

waste .in may 2011 a dicision was passed by the honorable 

SUPEREME COURT OF INDIA that the waste food grains divide 

among the poor people. There is no use of Green revolution if we 

do not take care about the wastage of such food grains .to avoid 

such food grains from wasting the idea of such godown strike 

into my mind 

Apparatus :- Thee transformers , L.D.R, IC, Spray pump, theft 

alarm, three motors Siren, water spray pump. 

1. Procedure:- In day time when light falls on L.D.R it effects the 

IC which changes the output and the voltage goes to the relay 

which effects the motor no 1. It open the roof of the godown. At 

night, IC again changes the resistance and relay clicks . the 

current goes to the motor no 2 which closes the roof of the 

godown. Hence in this way, the roof of godown automatically 

opens in the day time and closes at night. 

2. A small iron wire is wrapped around the door of the godown. 

When any thief trys to open the door of the godown. He will 

break the small iron wire. When the small iron wire will break, 

an alarm will ring in the nearest police station. When the alarm 

will ring, the police force will come into action and the thief will 

be caught. 

3.There is automatic spray system of pesticides in the godown. 

4.There is automatic dharma kanda for knowing the weight of 

the loaded trucks. 

5.There is automatic spray system of water at fire time. 

Aims : To protect the food grains from wasting.

HYDROGEN FUEL CAR 

2012 

Now-a-days we are using carbon-based fossil fuels for our 

automobiles, polluting our environment. We are in a 

crunch to find alternative fuels. The pressure is on. We 

can run our cars from pure H20, with the help of fuel cells 

which converts chemical energy into electrical energy. 

In this hydrogen fuel car, hydrogen and oxygen are 

separated by electrolysis of water and they are led into the 

'PEM Fuel cell'. 

Hydrogen gas flows through channels to the anode, where 

a catalyst causes the hydrogen molecules to separate into 

protons and electrons. The membrane allows only the 

protons to pass through it and it goes to the other side of 

the cell. The negatively-charged electrons flow into an 

external circuit to the cathode. This flow of electrons is 

electricity that can be used to run a motor car. 

In the same time, on the other side of the cell, oxygen 

flows through channels to the cathode. When the 

electrons return from doing work, they react with oxygen 

and the hydrogen protons at the cathode to form water. 

This water is again used for electrolysis. 


519

The main aim in designing this is to provide the concept 

of personal identity of each individual. The finger print of 

each person is collected and stored in the form of database 

by using oracal. At the time of voting, the option of the 

voter is taken along with the finger prints. The finger print 

is scanned and verified and then it is seat to chip. The 

processed image is transferred to hard disk. The option 

entered by voter is transferred to chip and stored in 

memory. If transferred signal or image is matched with 

stored record in the database then interrupt is given to 

memory. Then the option is considered in the count.

PARLIAMENT HOUSE SECURITY 

Parliament house security system. 'Security System' for 

our parliament house is the need of the hour to safeguard 

our parliament house and our leaders. All the drivers of 

the government officials, who drive into the parliament 

house are informed daily to tune the wireless transmitter 

radio wave frequency through secret code system. The 

wireless transmitter system instructs the vehicles to use a 

particular frequency which is picked by the receiver fixed 

on the entrance gate. The receiver cheeks whether it 

matches with their wireless RF Frequency. When both the 

signals are equal (Resonance happens) there will be a 

green signal in the receiver. The army personnel at the 

gate cheek the person in the car before opening the gate. 

The vehicle then moves on safety. 

In case a terrorists vehicle moves towards the entrance 

gate, there will be no signal in the receiver this will alarm 

the army personnel who start tiring the vehicle and 

destroy it. This will ensure the safety of our parliament 

house and the members of the parliament who serve our 

nation.

USABLE RESOURCES FOR 

CONSERVATION OF HUMAN LIFE 

Rain Water Harvesting :- Rainwater harvesting is the 

process of collecting rainwater from roof tops and 

directing it to an appropriate location where it is stored for 

ground water recharge. On an average, one spell of rain for 

two hours is enough to recharge 8000 liters of water. 

Hydroelectricity :- Hydroelectricity is the term referring to 

electricity generated by hydro power : The production of 

electrical power through the use of the gravitational force 

of falling or flowing water. 

Wind Energy :- Wind power is the conversion of wind 

energy into a useful form of energy, such as using wind 

turbines to make electricity, windmills for mechanical 

power, wind pumps for water pumping or drainage, or 

sails to propel ships. 

Solar Energy :- Solar Power is the conversion of sunlight 

into electricity, either directly using photo voltaics (PV), or 

indirectly using concentrated solar power (CSP). CSP 

systems use lenses or mirrors and tracking systems to 

focus a large area of sunlight into a small beam. PV 

converts light into electric current using the photoelectric 

effect. 

Deforestation :- Deforestation is the removal of a forest or 

stand of trees where the land thereafter converted to a 

non-forest use. Examples of deforestation include 

conversion of forest land to farms, ranches or urban use.

LIFE SAVING MACHINE 

2012 

Introduction : This is the simple machine to save the 

worthful life. It works based upon the Pascal jaw. In our 

country people dig a hole for Bore well. If they do not get 

water in the borewell, they would not close the hole. Lot 

of children falldown in this hole. Many accidents happen 

for that. The falling children life is question mark! We 

cannot save them easily because of narrow hole. So I have 

created the machine with simple principle and also save 

the child without any wound, in the short period. 

Material Used : Four syringes. I.V. set, Camera, Small T.V, 

light, two hands made by jute covered with gloves, 

longchain or rope. 

Scientific principle involved : Pascal law is used in this 

exhibit. When there is an increase in pressure at any part 

in a confined fluid there is an equal increase at each other 

point in the container. 

Construction and working: There are two artificial hands. 

This hands are made of jute and cotton. It helps to lift the 

child safely. These hands are connected with the two 

syringes. These two syringes are connected with the 

another two syringes by I.V. tubes. These tubes are filled 

with water. Two Hands are fitted in the frame. Camera, 

Mike, Light are connected in the frame. It helps to findout 

the child's position. 

First of all the hands are sent into the hole with the long 

chain. Then camera is operated. It shows the child's 

position. Then hands are put correctly near the child. Two 

syringes are operated. It gives the pressure to the another 

two syringes. These syringes make the hands to hold the 

child tightly. Then child is lifted up by the hands from the 

hole safely. 


527

WASTE WATER TREATMENT AND 

MANAGEMENT 

The main steps: The Main steps in typical water – 

treatment plants are coagulation , settling and filtration to 

remove suspended particles, aeration to remove the 

volatile substances most responsible for taste and odour, 

and chlorination to kill pathogenic organisms. 

Primary Treatment: For the treatment of sewage, primary 

treatment consists of mechanical filtration, screening, and 

settling, followed by chlorination. It removes 50 to 65% of 

the suspended solids. 

Secondary Treatment: In secondary treatment, the 

organic wastes are transformed by bacteria in the 

treatment plant, where oxygen is provided by aeration, 

instead of depleting dissolved oxygen in the receiving 

waters. The sludge from this process, consisting largely of 

bacterial masses, is concentrated and processed further in 

an anaerobic digester.

PHOTOGRAPH OF THE MODEL 

MODIFIED WINDMILL 

The main object of this project is to fabricate a modified wind 

turbine. Vertical-axis wind turbines (VAWTs) are a type of 

wind turbine where the main rotor shaft is set vertically. 

VAWTs offer a number of advantages over traditional 

horizontal axis wind turbines. (HAWTs). 

They can be packed closer together in wind farms, allowing 

more in a given space. This is not because they are smaller, 

but rather due to the slowing effect on the air that HAWTs 

have, forcing designers to separate them by ten times their 

width. 

The parts used in this modified windmill are: Turbine System, 

Generator, Battery, Inverter. 

In construction, the Vertical Axis Wind Turbine (VAWT) has a 

turbine system arranged vertically. The turbine system 

consists of two rims connected by the blades. The blades are 

designed from the easily available PVC pipes which are cut 

into two semi circle halves act as a blade and two ends of the 

blades are fitted with the rims and positioned vertically. The 

central exial of the bottom rim is directly coupled with the 

Generator and top rim central axial is connected with the 

frame by a shaft and bearings for distributing the axial stress 

and radial stress of the turbine. The generator is electrically 

connected with the battery by the power cable for storage of 

the electrical energy produced by the generator and 

connected with an inverter for converting the 6 V DC power 

into 230 V AC Power. 

The working principle of the VAWT, the kinematic energy is 

converted into useful mechanical energy by the turbine 

system. Due to the aerodynamic forces of the wind, the wind 

turbine starts rotation and the generator coupled with the 

turbine also rotates and the mechanical energy of the turbine 

is converted into the electrical energy which is stored in the 

battery and 6 V DC power of the battery is converted into the 

230 VAC power by the inverter for application.

WATER – POWERED BIKE 

The name of the project is “Water Powered Bike”. This 

technique consists of a bike, a battery and two units 

consisting of materials for electrolysis. The petrol tank is 

removed and these materials are fitted in bike. In this 

technique, due to electrolysis, water is converted to H 2 

and O. Since, oxygen burns completely, pollution is 

negligible. In the units, NaoH is profitable, eco-friendly 

and pollution free. The bike used is Bajaj – Boxer, a 100cc 

bike. Mileage is, for 1 litter water, 289 km-300km. The 

total cost is Rs. 27,850. The total weight is 137kg. This 

technique can be used in cars, trucks, buses etc. In this 

method, the bike completely runs due to water. 

The bike runs at an ordinary speed like other bikes. We 

can increase or decrease the speed like other bikes.

ENERGY SAVING SPEED BRAKER 

Now a days, our country is facing shortage of electrical 

energy. This project is aimed to produce and convert 

electrical energy at speed brakes. In India, we have busy 

roads and toll gates with large no of speed brakes. It this 

instrument is installed at speed brakes, when vehicle 

crosses the speed braker, its kinetic energy is converted 

into potential energy to the springs. In turn, it is 

transferred into electrical energy which can be used for 

operating traffic signals. This energy can be also stored in 

storage batteries and used at right for street lighting 

purpose. If it is implemented energy shortage could be 

tackled to some extent. 


533

MULTIPLE ENERGY POWER PRODUCING 

I have made this project for the substitution and the 

compensation of the power cut. By simply pedaling the 

cycle, we can activate all the electrical appliances like 

mixi, grinder, LED lamps, charger lights at the home, can 

be activated to cycle bearing measuring 1.5cm is welded. 

Another bearing is fixed on an iron rod measuring 2.5cm. 

When the cycle is pedaled, the bearing touches the back 

wheel and there is a belt attached to the pedal, by the help 

at the belt attached in the pedal. When the rod is rotating, 

the mixi is also moving. When the cycle rod is attached 

with the grinder and it is welded too, by the help of the 

grinder is moving. 

At the top of the cycle stand, there is a dynamo of 13 volts 

is fixed. There is a dynamo rear the pre wheel. Both are 

interlinked with a chain. When the cycle is pedaled, DC 

current is produced. It save in 12 volts car battery. It is 

connected into AC current with the help of an Inverter. 

We got 230 watts current to activate any home appliance. 

By this method, we save electricity and the excercises, we 

do by the cycling this will help us to be away from 

diseases.

EYE BLINK SYSTEM 

2012 

— Now a days, one of main reasons for accidents 

sleeping of driver. 

— To avoid this, we use a sensor which is attached to a 

microprocessor which is programmed as such that. 

— If the drivers no. of eye blinking (opening and closing 

of eye lids) below 20 per second, the alarm will blow, 

so that the driver may awake. 

— If the drivers no. of eye blinking is more than 20, 

there won't be any alarm. 


535

Keep This Way:- 1. If we use rain water harvesting in 

every house, we can avoid the ground water decreases. 

2. If we avoid to put plots, we can save our cultivated 

lands. 

3. If we utilize Filter factories of S, Co, Co2 and So2 to 

avoid environmental pollution. 

4. Education for all - in free Education from SSA, RMSA. 

5. Avoid hunting Animals. 

6. Avoid pollution of ponds and rivers with sewage water 

and effluents. 

7. Use Modern Technologies for wind mill, Satellite, Smart 

Class, etc… 

8. To grow plants. 

9. Instead of avoiding plastics, Reuse the plastics for 

petrol, gas, road etc… 

Get That Way :- 1. Developing buildings will become a 

garden. 

If we protect our world environmental in this way, the 

world will become a prosperous and progressive world.

PLASTIC ROAD 

2012 

The very big problem that we are facing is the 

environmental pollution caused by waste plastics. Daily 

crores of Indian People use and throw plastic materials 

such as Tea Cups, Water Tumblers, Water Bottles, Carry 

bags etc… These plastics takes several years to 

decompose, which causes our fertile land to pollute. 

During rainy days it would not allow the rain water to 

penetrate through it which causes ground water level 

depleting. And also water pollution. Suppose we burn 

these plastics, it will cause air Pollution. 

We can convert such waste plastic material is to useful 

one by making plastic Road, Here we have dissolved these 

plastic into an organic solvent like Retrol in 10:1 Ratio to 

make a plaster. That pasty material we used for making 

Road instead of Tar. 

Uses :- First, we can convert a waste highly environment 

polluting plastic material into useful one. 

Second, It is more economical than that of tar road, since 

life time of plastic road, is greater than that of tar Road. 

During rainy days plastic roads are not easily damaged 

like tar roads, During summer days, it would not easily 

like melt tar road. 


537

MODERN AGRICULTURE 

The new systems used in farming is called modern 

agriculture. I have created some idea's that was water 

saving plastic Banners are used in farming. New Drip 

Irrigation and new sprinkler systems in forming rain water 

harvesting and correct producing different model of over 

tank new fertilizer machine new method of all agriculture 

works and etc.

HYDRAULIC ROBOT 

Introduction : A robot is a machine that can be programmed 

to perform a rask. 

A robot is not intelligent by itself and can perform only those 

tasks for which it is given a set of instructions or program. 

Computers act as the robot's brain. 

End Effectors: The end effector is attached to the wrist of the 

robot arm for the purpose of loading, unloading, transporting 

arts or performing an operation on work piece. If the robot 

has more than one arm, there can be more than one endeffector 

on the same robot, each suited for a specific task. 

1. End of arm tooling, 2. Gripper 

2012 

End of Arm Tooling : End of Arm Tooling weight should be 

minimum, since it is added to part weight to determine the 

maximum payload. It should be able to grasp, life or release 

the part of family of parts required by the manufacturing 

process. 

Grippers : Grippers are end effectors used to grasp and 

manipulate objects during the work cycle. The objects are 

usually work parts that are moved from one location to 

another in the cell. Owing to the variety of part shapes, sizes, 

and weights, grippers must usually be custom designed. 

Conclusion : This robot is used for pick the object in one 

place and place that object in required places. Some 

industrial works are harmful for humans. This robot is 

mainly used to reduce the risk process and consuming time 

and avoid labors. Human are tired of hard work such as 

assembly line, material handling etc. this robot does all those 

things is mainly reduces the manual work out robot is 

designed at low cost as well as high efficient one. This 

project is to give the way for providing bigger effective robot 

for industrial applications. 


539

RECYCLING THE WASTE 

MATERIAL TO AVOID POLLUTION 

The main aim of my project is to control land pollution by 

recycling the natural waste. 

My project Utilizes the waste such as: 1. Guano Excreta, 2. 

Cow dung, 3. Bone ash. 4. Plant ash, 5. Vegetable waste, 6. 

Feathers, 7. Egg shell, 8. Goat Lever. 9. Vasambu, 10. Neem 

Leaves, 11. Kernel Powder. 

These are rich in micro & macro nutrients which are 

essential for the plants to grow healthily. 

A mixture of the mentioned ingredients in the ratio of 

1:1.5:1:1:.5:.5:1:1 is powdered & used as pesticide & 

fertilizer. The ingredients have the following reasons for 

efficient Utility: 

—20-20% increase in the yield of crops. 

—Controls land pollution. 

—Increases soil fertility. 

—Easy on the pocket. 

—Easily accessible. 

So we have to set right this problem by using this organic 

fertilizer which is having all minerals which is essential to 

plants by also act as a natural pesticide to control many 

pests. Thus, I hope this world will sparkle with ecstacy 

through my project.

ENERGY FREE AIR CYCLE 

2012 

My experiment is name is “Energy Free Air Cycle”. The 

main concept of the project is to minimize the cost of the 

transport, and avoid pollution of the world. We can ride 

this as a bike without pedaling and feel. This cycle is gift 

for the middle class people and old-age people. This cycle 

is operated only by air (compressed air). In this cycle, the 

compressed air is passed though the cylinder, and the 

axle of the cycle is rotated by air by the pneumatic 

cylinder (piston). The piston is regulated by a solenoid 

valve. To operate the DC compressor, we had taken a 

battery. To avoid the replacement of battery, we had taken 

a solar panel. It converts the solar energy into electrical 

energy. So, our main concept of low cost is applicable. 


541

CURRENT FROM SEPTIC TANK 

In our method, we are producing current in the home 

itself. During the construction of septic tank, it is divided 

into two. Septic tank is covered with paddy straw for 

maintaining the temperature. C:N ratio 30:1. It is 

maintained by adding food and fruit wastes in the form of 

essence. Little lime is added for pH. Unaerobic condition 

destroys the harmful bacteria. We can easily get 4 units 

current from septic tank along with poultry waste. 

Approximately 30 kg/day poultry waste and the above 

procedure from human waste we can produce 3 m3 gas 

perday. 

Gas from septic tank along with poultry waste consists of 

mainly methane, small CO is used for the growth of 

2 

beneficial bacteria. Methane is allowed to fall into the 

Internal combustion Engine. Out put is CO This is 

2 

eliminated by using ROBOT TREE. Now we are getting 

A/C current. 

In our project, there are no long distance wire 

connections. No Electricity Department. PRODUCTION, 

TRANSMISSION, DISTRIBUTION are the three stages in 

the current supply. In transmission most of the current is 

wasted. Transmission is absent in this method. Also, we 

can create India without power cut.

AUTOMATED RAILWAY GATE 

This invention can be helpful to avoid accidents in 

Railway department. It will be helpful to minimize labors 

and avoid accidents. 

Function 

nd 


2012 

Every Kilometer has four switches in the Railway track. 

That switches are connected to Red light and horn. When 

the train engine touches the four switches, the light will 

glow and horn makes sound. So, the level crossers and 

animals will be safe. 

Rotating gate is also fixed. Positive and negative 

connection is fitted properly with the motor. When the 

train crosses the railway gate, one particular switch 

touches the train. At that time the rotating railway gate 

will automatically be locked. After crossing of the train, 

the gate rotates opposite side, and the gate will be opened. 

This is the way I have made this experiment. 


543


Imagine a world where the land locked state of Idaho is 

now prime ocean front property and almost all of the 

major cities in the world are covered by water. This isn't a 

science fiction movie. Global warming is a serious threat 

that could threaten the existence of our civilization. 

Environmental pollution, over population, communicable 

diseases, newer pests and loss of national resources are 

today's global problems. 

The phenomenon of global warming is extremely serious 

matter. So I have selected this topic (Global warming). In 

this model I show the damage of O3 layer. The emission of 

gases into the atmosphere from burning fossil fuels. These 

gases, with CO being the main culprit, prevent solar heat 

2 

from escaping from the earth's atmosphere, resulting in a 

rise in temperature, or the green house effect. 

These effects include rising sea levels, killer heat waves, 

out-break of tropical diseases, altered weather patterns, 

increased number of floods and affected agricultural 

harvests. In my model, I have pointed out the hospitals, 

polluted lakes, deforestation, air pollution because of over 

population & usage of transport. 

From this model, we can understand that any change in 

natural environment will affect living organisms directly 

and produce harmful effects.

HUMAN SECURITY SYSTEM 

2012 

Our nation is fully industrialised. The industries of 

Cement, Crackers, Sugar, Mine, etc are functioning here. 

There is no security to the labours in the industries. For 

this great impact, to save all the labours, this Human 

Security Systems is designed. 

When the System is fit in the industries, the labours Must 

wear helmet. If they don't wear helmet, the sensor in the 

system stops all the machines. 

The Smoke Sensor in this system identifies alcoholic 

smell and smoke and stops the machines automatically. 

The labours even if they wear helmet must not Smoke 

and not use alcoholic drinks. This is another great 

advantage of this System. 

Accidentally fire spreads to any part of the industry. The 

smoke sensor stops the machines automatically. So, in 

future, we may fit this system in two wheelers & four 

wheelers. 

This Human Security System prevents the loss of human 

beings, avoids damages of machines, products and 

vehicles.

GEOTHERMAL POWER PLANT 

Introduction: We get electrical energy from various 

sources such as sun, water, wind sea waves and atoms. In 

the same way, we get the same from Geothermal Power. At 

present, it has been implemented in the ice lands like 

U.S.A, Japan, Mexico and so on. 

Function : Pressurized cold water is sent down the 

injection well where the hot rocks heat the water up. Then 

pressurized water of temperature greater then 200°F is 

brought to the surface. The pressure of the steam is being 

increased and it emits the hot water with the highest 

pressure. This energy is used to rotate the turbine. This 

kinetic energy is converted into Electrical energy finally. 

Advantages : 8.3 million tonnes fuel can be saved. It also 

prevents the emission of Co2 of nearly 40 million tonnes.

ELECTRIC CHIMNEY 

2012 

World's most effective and dangerous pollution is “Air 

Pollution”. To Prevent air and control air pollution, I 

invented a chimney. 

Construction: It consists of a copper wire suspended with 

it and an aluminum foil is made to surround it. An 

induction coil is made to connect with it. There are two 

terminals connected to the induction coil, one is from 

aluminum foil and other is from copper wire. This 

induction coil will act as a capacitor. When a potential of 

20,000 volts is supplied to this circuit, it will create a 

field. 

Working : Smoke is a colloid of air and carbon. Colloid is 

nothing but a dispersed particle dispersed in air medium. 

Since, carbon is weightless, it can casily float in air. To 

avoid the floating of carbon, we collect the carbon 

Particles together. But carbon particle won't adhere with 

each other. Because it contains electric charges. We 

should remove these charges, to make the carbon particles 

together as mass. When the smoke enters into the field, 

the charge in the carbon particles are removed. So, the 

carbon particles adhere with each other and it 

precipitates. So, the pure air is let out from the chimney. 


547

Aim :- Best from worst Dirty Water to produce Current 

Energy Conversion :- Here Mechanical Energy is 

converted into Electrical Energy 

Principle :- It works under the principle of the Flemings 

Right – Hand Rule. Induced current and magnetic field or 

perpendicular to each other. It works under the Principle 

of Dynamo. 

Explanation :- The apparatus consists of a water cane 

which is filled with water. Slotted wheel is attached to the 

Dynamo when water falls on the slotted wheel which is 

take a turbine. When the turbine rotates, the current is 

produced 

Uses :- This is a renewable source of energy. How we are 

using solar energy. Likewise we can use this energy. If 

each house had this apparatus so that they can produce 

their own electrical energy. For half Litre of water we can 

produce 24 Volt of Energy. To run a T.V, we need 240 volts. 

For this, we need 10 liters of water every day. Every house 

is using 10 liters of water. So that per house we can 

produce 240 Volts of energy. With this, we can glow a forty 

wats bulb.

TRAFFIC CONTROL AND ACCIDENT 

Recent Statistics show a number of road accidents. People 

drive carelessly and suffer from severe physical 

disabilities. The members of their families suffer a severe 

loss because of their mistakes. This experiment has been 

designed to prevent road accidents using a few 

mechanisms added to the ordinary vehicle [Two wheeler]. 

A sensor has been designed with the vehicle which does 

not allow the vehicle to move if the driver is drunk. The 

chemical test for alcohol is used along with the sensor. To 

make the helmet a mandatory accessory while driving, a 

mechanism has been added to the vehicle. It allows the 

vehicle to start only if the driver wears the helmet. 

Another mechanism has been designed with the vehicle 

which will allow the vehicle to move only if the side 

stand is lifted up. I believe that these three mechanisms 

together will help in preventing road accidents efficiently.

Aim : To heat the water by using solar energy. 

Apparatus Required : Glass plate, black paint, (Asian), 

asbestos, saw dust, Refrigerator or A.C. Condensor 

(Copper coil). 

Settings : Wooden box is made. Saw dust (insulating 

material) is stuffed tightly without giving any room for air. 

Asbestos sheet is laid over the stuffed saw dust. Entire 

area of the asbestos is painted by Asian black paint. 

Condensor, painted in black, is kept on the asbestos over 

the condenser, with 45° angle glass plate is kept. One end 

of the condensor is connected to the water reservoir 

(waste saline bottle). The other end is kept open, through 

which hot water is coming out. 

Procedure : The entire set up is kept in sunlight. Water is 

made to flow through the condensor. Regulator is adjusted 

so that water slowly runs through the coil. By this way, 

water gets radiation emitted by black body. Black body 

absorbs energy from the sunlight and radiates energy. This 

radiation is passed to the water which is slowly running 

through the coil. By this way, water gets heated. 

Uses : 1. Hot water for bathing, 2. Drinking water, 3. 

Rotating turbine, 4. Cooking, 

5. Conservation milk, 6. Save fuel, 7. Rectifying air 

pollution 

8. Useful in electricity unavailable places. 

9. It can be used in hospitals, restaurants and laboratories.

ENERGY CONSERVATION ZONE 

The energy resources are being exploited and the need of the hour is 

to conserve energy. The aim of my project is to find the ways to 

minimize the energy consumption and waste heat energy recovery. 

My project includes (i) Thermal insulated cooker (ii) Natural 

Preservative system (iii) Thermo electric power generator & (iv) 

Electricity from market wastages 

(i) Thermal Insulated Cooker : I Prepared the thermal insulated 

cooker with cardboard box and hay. This system will not allow heat 

transfer from inside to outside by anyway (conductor, convection & 

radiation). Explanation of working with an example is as follows: To 

cook rice, water and rice are taken in a pot and heated on stove. 

When it starts to boil, the pot is removed from the stove and kept 

inside this thermal insulated system. As there is no heat loss, the 

temperature is retained within the system which is enough to cook 

the rice. Thus, the energy consumption is minimized. 

(ii) Natural Preservative system : (No pollution! No electricity!) 

This system can serve as a substitute for refrigerator and electricity 

is used. This is designed with a wooden box, mud pots and sand. 

Mud pots are kept in the wooden box and wet sand is filled in the 

gaps. By slow evaporation process, the vegetables kept inside the 

pot get cooled. Water is sprinkled periodically and this water be 

utilized in a useful way by growing coriander on the sand. Thus this 

model helps to minimize the Energy Consumption. 

(iii) Thermoelectric Power Generation : (Waste Heat Recovery) Most 

part of energy consumed by industries is discharged as thermal 

losses. To utilize this waste energy, the thermoelectric power 

generator is used. This generator is based on “see beck effect” and 

does not contain any movable part, thus zero noise level. 

Thermocouples are used here. When one junction of the 

thermocouple is heated, due to temperature difference, electricity is 

generated. This thermoelectric generator can serve as a good device 

in waste heat recovery for industries. 

(iv) Electricity from Vegetables and Fruits Wastages : Electricity is 

generated from waste vegetables and fruits collected in markets. 

Waste vegetables and fruits are taken in different vessels. Series 

connection is made with copper and zinc plates, taking copper as 

anode and zinc as cathode.

BIO-DIESEL PREPARATION FROM 

WASTE AGRO – BY PRODUCTS 

Abstract 

Bio-Diesel Preparation from Waste Agro byproducts Aim : 

To prepare alternative fuel for diesel engine from various 

waste oils like Pinnai oil, Used vegetable oils etc., 

Through this invention, we can give the solution for the 

following major problems. 

1. Energy Crisis and, 2. Pollution Control. 

Materials and Methods: In the preparation of BIO-DIESEL 

the following steps are involved, they are: 1. Stirring 

Process, 2. Sedimentation Process, 3. Separation Process. 

First, we take any waste oil 15 liters in a container, along 

with the oil 15ml of FORMULA-X is added. Then, the 

solution is stirred for 30 minutes with the help of high 

speed motor having 2000rpm. Then the stirred solution is 

kept for sedimentation process for 3 hours. Then the 

glycerin in the solution gets sediment in the bottom of the 

container. The upper clear portion is the pure BIO-DIESEL 

The percentage of bio fuel obtained from the various 

waste oils differ from each other. In that way, the amount 

of bio-diesel that prepared form PINNAI OIL is high, and 

also the pinnai seed containing 50% oil of it's dry weight. 

And it is not also used for any other edible purposes. The 

percent of amount of bio-diesel in pinnai oil is 80%. 

This bio-diesel is an ECO-FRIENDLY FUEL. because this 

fuel emits only few amount of carbon-dioxide. But fossil 

fuel emits more amount of co2 and also other harmful 

gases like No2, So2, etc,… 

We tested out bio-fuel with out 5Hrs power diesel engine 

for about 6 months. It is running well and does not cause 

any damage to the engine.

GREEN HOUSE 

2012 

This is a green house to grow plants in the desert. We 

have to dig the land for 10 feet and put sand and coconut 

fibres. Coconut fibres Prevent water evaporation and also 

they have become manure for the plants. The green cover 

in the roof prevents the plants from the ultra violet rays of 

the sun. In the desert, during morning, when the 

temperature begins to rise above 45°C, the fan works and 

reduces the temperature. At night, it will be very cold 

there. So when there is no sunlight, the light will be on. 

So the fan and light regulate the temperature for the 

plants to grow. The water motor works and the water goes 

to the plants when the sand is dry and its stops 

automatically when the sand becomes wet. 


553

EFFLUENT WATER TREATMENT 

Aim :- To treat the effluent water in a effective manner and 

to reuse the water. 

Where to use :- It can be used as sewage water treatment, 

Dye house Effluent water Treatment and Leather 

Industries. 

Treatment scheme :- The raw effluent water is first mixed 

with Poly Aluminium choloride, Poly Electrolyte and Lime 

Water. These chemicals are mixed in mixing tank. The 

mixed water will overflow to the primary clarifier. Here, 

all the sludges will settle down. The settled sludges will 

go to the sludge drying beds. The overflowed water will 

go to the aeration tank. In Aeration tank, we are 

cultivating the Bacteria with the help of cow dung. Here, 

we have to pass the air continuously through compressor 

to cultivate the Bacteria. This Bacteria will help to reduce 

the BOD and COD in the water. 

From the aeration tank, the water will overflow to the 

secondary clarifier. Here the sludges from Aeration tank 

will settle down. From the secondary clarifier, the water 

will overflow to Reverse osmosis feed tank through the 

sand filter and Bag filter. From Reverse osmosis Feed tank, 

the water will go to Reverse osmosis system through 

Activated carbon filter and Reverse osmosis membranes. 

In the Reverse osmosis membranes, the good water and 

the Bad water are separated. 

We can use the good water for other than drinking 

purpose. The reject water will go to the evaporator and 

solar Evaporation Ponds.

ROLE OF VETTIVER IN 

CONSERVATIONS OF LAND RESOURSES 

“Vetiveria Zizanioides” which is commonly known as 

'Vetiver' grass is a plant which conserves our land 

resources effectively, One day our teacher told about 

vetiver grass and its conservation properties. Immediately 

we searched for it, But we could not find it anywhere, As 

our village is situated near Kerala many of our relatives 

are working as labours there, we have the opportunity to 

go there for holidays. There we have seen the plant 

'Vetiver'. So it is very easy to pursue this project with the 

help of our guide teacher. 

The specific objectives of this project are : 1. How it 

conserves soil, 2. How it helps for waste water treatment. 

3. To bring this plant to our village. 

With the help of our guide teacher we went to Kerala to 

bring vetiver saplings and for soil collection. In our visit 

we saw the places where vetiver grows are not affected by 

soil erosion and landslides. Because it has a deep, tough 

root system form 3m to 5m. 

Secondly we have done an experiment for waste water 

treatment. As its root system is tolerant of high levels of 

heavy metals and absorbs higher concentration of 

nutrients and agrochemicals, the water can be easily 

purified. 

With the effect of this project it impacts so many people 

in our village we make awareness among our friends, 

relatives, farmers and students. We make them to plant 

vetiver in their houses, farms and also in our school 

campus. 

This project makes us to think so many ways and also we 

have given some recommendations to our society to 

conserve our land.

PREVENTION OF TRAIN 

Aim 

Most of the people of our country use train for travelling. 

because of its cheaper fare when compared with other 

means of transport and also for the fact that travelling 

time is much less than other road ways. As our nation is a 

developing country we have to maintain the transport 

system without any hitch. Now-a-days we face so many 

problems in the train track such as cracked or damaged, 

bombs placed in the track or any object or animals on the 

track which lead to massive loss of life as well as damage 

to the train. To overcome all the above problems, we can 

put into use this pilot trolley method. Using this method 

we can avoid accidents. 

Objectives: 

To sense on object as well as a train approaching on the 

same track. 

Sending information to the train to stop it. 

Saving the train and human lives from any damage. 

To avoid train accidents. 

Use: 

This trolley senses any object, train or bomb in the track 

and sends message to the train and the train can be 

stopped automatically. 

It is very useful to deploy in guardless railway crossings 

and in forest areas where animals could cross and in areas 

where terrorist attacks are possible. 

By using this type of device we can prevent the train 

accident and save a number of human lives.

natural fertilizer can be prepared and shared between 

different farming to best effect. 

Recycle Method : 

2012 

Sericulture → Vermi composting from waste of silkworm 

→ Manure to plants and waste grains feed to Birds → 

Fish farming →Manure fishs waste cultivate mulberry → 

Sericulture. 

Procedure :- 1. To display various stages of sericulture 

and show feeding and build the cocoon stage of silk 

warm. 

2. Wastage of silk Worm and leaves are put in a tank for 

weeks along with earth Worms which converts the 

wastage into a good fertilizer. 

3. The Wastages from poultry farming are directed to a 

pond where fish farming will be carried out. The 

Wastages from poultry farming will increase the 

production of fish due to its high nutrient content. 

4. The fish farming waste water is then again used for 

cultivation of mulberry. So the wastages from each of the 

agroculture is used to prepare a good fertilizer for the 

other. 

Merits :- Zero Waste Management, Increase Employment, 

Environmental, High Income, Life Protection, Water 

Saving, Entertainment.

AUTOMATIC SOUND MAKER 

Name of my project work is “AUTOMATIC SOUND 

MAKER”. It is used to find out an accuesd (or) prisoner 

who will try to escape from the cell of a prison. The 

expense to make this system is very low but rich in use. 

Procedure : The upper layer of the floor in the cell is kept 

on some springs placed at several places. The mechanism 

or the electric circuit is shown on the chart. When all the 

prisoners are present in the cell the circuit is not 

completed. If anyone will leaves out and tries to escape 

from the cell, the weight of that prisoner reduces. Because 

of that the spring expand and the electric circuit is 

completed. Due to that, the current passes through the 

circuit and alert our officers. So we will easily find out 

and capture that accuesd or that prisoner. All of this 

system is controlled by a switch.

HOME AUTOMATION 

At present, all the electrical equipments we use in our 

daily life, such as lights, fans, audio / video systems, 

electric stove, etc., are controlled by electrical switch 

boards. Our physical presence is very much required to 

operate these equipments. However, modern day life 

demands both the husband and wife of a house to go for 

work. Under such a situation, a device to operate the 

electrical equipments from remote places such as offices, 

schools, etc., is very much required. 

The device used in particular experiment is a Mobile 

phone. The Mobile phone here is being used as a multi 

purpose remote to operate the various electrical items like 

light, fan, mixie, audio/video systems etc., from remote 

places. 

In this experiment a mobile phone is connected with four 

various equipments – a fan, a light, and FM radio and a 

mixie. 

By calling this Mobile number from another mobile 

phone, all the four equipments can be operated from 

anywhere. 

This device will be useful not only at home but also. 

1. To the farmers with large area of land to operate their 

Electrical Motor used for watering the land. 

2. To large corporate houses to have control over various 

floors / segments / departments. 

3. To control any electrical fire disasters, off the site. 

As this experiment used the items already available with 

us, the device will be cost effective, efficient and user 

friendly.

LIGHT PROPERTIES AND USAGE 

Introduction: 

Now a days students grasping power about science is very 

low. This exhibit provides proper explanation with visual 

idea. 

Project Explanation : 

We have seen in our books convex lens converges and 

concave lens diverges with a piura illustration as but we 

do not know real happening of this. This exhibit clearly 

explains using laser light. Similarly we can explain 

refection, refraction, total internal reflection, etc… 

We can demonstrate clearly multiple reflection, optical 

illusion, virtual image, interference, diffraction and 

tyndall effect etc… 

Uses : 

Laser light fencing may be used to prevent any 

interference of animal with people and also can be used 

as burglar alarm. Infrared light may be used to study the 

animal behavior, in the dark. Ultraviolet radiation may be 

used to check the genuiness of currency note. 

Conclusion : 

nd 


2012 

They above explanations are useful for the students to 

understand clearly the light proportions and gives duper 

knowledge.

CONSERVATION OF BIO-DIVERSITY 

CONSERVATION OF BIO – DIVERSITY --- AT A GLANCE 

In the beginning there was World and the World was with us, 

filled with magnificent Flora and Fauna. As population increased 

and technology developed, men started exploiting the Nature 

with all her renewable and Non-renewable resources bringing 

every living being to the brink of destruction calumniating in a 

deplorable situation paving for the survival of the Fittest. 

Though late, having realized this hazardous and progressively 

diminishing process of Nature, men started conducting various 

studies for the preservation of Nature. Our study is one among 

such an attempt that we humbly put forward to bring awareness 

among the common man in the augmentation of Natural Biodiversity. 

Further, our study throws light on the imminent danger 

due to anthropogenic activities coupled with the Natural 

calamities. 

For easy feasibility and understanding, we adopted the Play Way 

Method, which seems silly yet comprehensible even to an 

average on looker, to explain the concept of Bio-diversity. We 

introduced this concept through a familiar game known 'Snake 

and Ladder'. The snake represents destruction, deterioration and 

the adverse effect of all constructive development and the 

exploitation of Nature, while the ladder symbolizes harmonious 

synchronization of development, the very Existence of life, 

Biotic and Abiotic, unity brought about. 

Every Activitix either man made or natural , have its direct 

impact on the environment. The prevention, control and the 

protection of all developmental activities can minimize the 

volume and quantity of destruction which is the need of the 

hour. Through this chart, we try to figure out events and

INDIA 2025 (HYDROPONIC HOUSE) 

Hydroponics means cultivation of cash crops and food 

crops in a Liquid. Nutrient medium. Now-a-days, many 

cultivable lands have been converted into multi-storied 

buildings, Factories, multi national companies etc. 

Vast, green, beautiful forest and animal have been 

destroyed for the commercial purposes. So, in future, 

there will be no cultivable land for agricultural purpose. 

This conditions is already prevailing in the countries like 

Japan, China etc… So, they have already chosen an 

alternative method for Agriculture is Hydroponic culture 

(Soil less Culture). 

In India, it is not so far. Very soon, Indian human 

resources by destroying natural resources will switch over 

to this new method of cultivation is Hydroponic culture. 

As a student at present, an attempt has been made to 

produce Home Hydroponic tomatoes on the top of the 

house.

NATURAL DISASTER RESCUE 

2012 

Natural Disaster Rescue Machine functions by Hydraulic 

Power (using water pressure). This is functioning without 

any fuel. So, it saves the environment from the pollution 

and also saves the money. 

Main aim of this machine is rescuing human lives from 

debrises of the natural Disaster and reduce the expenses 

of construction works by using this machine in 

construction works. 

This machine is used in rescue activities in earth quake 

and remove the soil and rocks which are slipped by land 

slide on the road in hill areas. 

During the cyclone and sunami, it is used to lift the fallen 

trees and the properties from debrises. In road accidents, 

it is used to lift vehicles which fell down on the road and 

the ditch of the road side.

POWER GENERATION FROM THE 

AGRICULTURE PUMP WATERFORCE 

Most of our village farmers are using water pump-sets for 

their irrigation. Farmers use the water for their irrigation 

but nobody is utilizing the force of the water. Yes, the 

force of water is wasted there. 

Why not we utilize the force of the water to the power 

production? Simply, we have to fix a turbine with dynamo 

in the path of the water near by the pump-set out put. The 

force of the pump-set out put water is high enough to 

rotate the turbine and to produce the power. We can 

convert this D.C. Current into A.C by using transformer. 

This system of power production will be applicable in 

various places like house hold water pump-sets, water 

supplies from over tanks and in water pumping stations 

(where water is pumped from oneplace to another place) 

etc… 

We strongly recommend this concept to our Government 

to utilize it in large scale. 

“Don't waste the waterforce-Convert it into power-our 

nation will shine!”

ELECTRICITY GENERATION AND MULTI 

PRODUCTS FROM SAW DUST 

Aim : Production of electricity using wood wastage. 

Process : A container consisting of two outlets half filled with 

saw dust is heated and subjected to Destructive distillation. 

While doing so, it produces wood gas. The wood gas coming out 

from one of the outlet is sent to the turbine and the gas from the 

other outlet is sent to the burner of the next container which is 

also filled with saw dust. There, this wood gas is used as a fuel 

for heating the next container as it is a combustible gas. This 

reduces the depletion of fuels This process can be continued for 

a series of similar connections. 

Advantage : - The main advantage of this project is production 

of electricity in a cost effective and using a non-polluting 

renewable source of energy. 

By products of saw dust : 

Wood charcoal 

nd 


Exhibition 

& Project 


Wood charcoal is mostly used as a fuel and acts as absorbent of 

poisonous gases. It is also used as a decolorizing agent and also 

used in gun power. 

Carbon black : It is used for the manufacture of a large number 

of organic components e.g. benzene, toluene, naphthalene, 

phenoyl etc. They are also used for the manufacture of dyes, 

drugs, disinfectants etc. 

An aqueous distillate called pyroligeneous acid which is a 

mixture of acetic acid, methyl alcohol and acetone. 

Gas carbon :- The carbon deposited along the sides of the retort 

is called gas carbon. It is a good conductor of electricity and is 

used for making electrodes. 

Conclusion :- Effective resource management is necessary to 

prevent depletion of natural resources. Plans for natural 

resource management and conservation have been suggested 

and implemented by concerned groups in government, industry 

and in communities. These plans include recycling, substitutes 

and reuse. I believe that my project satisfies all these factors. 


ENERGY IN NATURE 

Energy can be derived from many sources. Energy is 

neither created nor destroyed, because one type of energy 

is converted to the other. The natures such as solar heat, 

heavy wind, water current, rotating objects and decaying 

bio-waste are some of energy sources considered in this 

project, which are unharmful and to produce other 

intermediate useful products. 

Solar energy is used to get electrical energy using solar 

panels, which are widely used as solar lamps, heater and 

related products. 

Wind energy is another common nature from which 

electrical energy is obtained using windmills in many 

places such as sea, forest, hill and mountain bounded 

regions.

PEDAL OPERATED WATER 

The need of the hour is “Save energy for a better future”. 

To control the energy crunch, alternative method needs to 

be adopted. If the same trend continues down the lane, in 

25 years existing resources may get totally exhausted. 

Keeping this in mind, we have developed a “PEDAL 

OPERATED WATER PUMP” which works on the basic 

principle of suction pressure and vacuum. 

This pump doesn't need electricity, highly userfriendly, 

not too complicated, and no periodic maintenance is 

required. It is highly cost effective, and the parts can be 

easily replaced and it is portable. 

This pedal can be operated using less mechanical force. 

The underlying principle is very simple and the laymen 

like farmers can use it effectively. 


To safeguard trains and men's lives: 

1. From terrorists who attempt to disconnect rail route 

with bombs. 

2. From unexpected fire inside the compartments. 

For the convenience of the passengers: 

3. To announce the arrival of Train at Railway stations, 

inside the compartments. 

4. To make illuminated with sudden light facility while 

entering caves. 

5. To make compartments airy with additional fans during 

rush hours. 

To utilize maximum benefits from trains particularly to 

get electricity by setting devices on top of every

Exhibition 

& Project 


This study gave a positive result to control the larvae of 

mosquito. In the present study, the dried and fresh leaf 

extract of calotropis gigantean and Bougainvillea 

spoctabilis were used to kill the larvae. It is found out that 

it is a method to eradicate larval forms of mosquito. 

From this, we conclude, that this method can be done 

further in an improved manner to kill the larval 

effectively. 


REVERSIBLE ENERGY 

FROM WASTE 

Electricity is produced by using non-biodegradable 

material like plastic. Plastic is polluting air, water and soil 

and this should be managed and checked to save our 

country from pollution and ozone depletion. 

This project is based on air pressure. Plastic is burnt in a 

heat resistant container. Plastic materials are burnt and 

the fans rotate with the help of turbine and electricity is 

generated. The fumes that are generated are recycled to 

the container and so it does not pollute the air. 

Hence waste materials are managed and electricity is also 

produced without polluting the atmosphere.

OXYGEN LEVEL ALARM SYSTEM AND 

IV FLUID LEVEL ALARM SYSTEM 

I have invented two alarm systems, namely the oxygen 

level alarm system and IV Fluid level alarm system. 

Till now, all over the world, there is only visual 

inspection of level of Oxygen supply to the patient 

through flowmeter. First time in the world, I have 

invented the Oxygen Level Alarm System. It gives an 

audio alarm when there is even a fluctuation in the flow 

of Oxygen, in order to prevent the patient from entering 

into Hypoxic Conditions and save their life in the golden 

seconds of their life. 

I have also invented an IV Fluid Alarm System. Nowadays 

the nurse patient ratio is not 1:1 And so they have to look 

after various other patients. If the IV Fluid gets over and is 

not changed, the patient may encounter with various 

problems like Air Embolism, Backward capillary suction 

of blood and block in IV Catheter. In order to prevent the 

patients from such problems, my IV Fluid Alarm System 

has to be used which would save the life of the patient in 

their golden hours of life. 


GREEN HOME 

According to IEA, xisting buildings are responsible for more than 

40% of the world's total primary energy consumption and for 24% 

of global carbon dioxide emissions. Hence the solution is a Green 

Home. Salient features of my project are:- 

Environmental Benefits:- 1. Clean energy through 74 watt solar 

panels producing 500 watt/day. 

2. Exfoliated vermienlite weathering course-decreases 5-8°c inside 

home. 

3. Improve air anality through roof gardens. 

4. Chemical free treatment of drinking water by strychnos 

polatorum. 

5. Wastes create no pollution, as they become valuable raw 

materials for enhancing soil fertility through vermicomposting. 

6. Increased soil productivity through improved soil quality. 

7. Increase in Ground water levels through Rain water Harvesting. 

8. Recycling of water in Septic Tanks by Bacillus subtillis. 

Social Benefits :- 9. Enhance occupant health and comfort. 

10. Improve overall quality of life. 

Economic Benefits :- 11. Provides additional source of income 

generation. 

12. Boost to rural economy. 

13. Cost- effective pollution abatement technology. 

14. Considerable amount of money saved on electricity by using 

solar panels & vermiculture. 

The implementation of my project will ultimately bring forth a 

new dimension in economically distressed areas of India. Its cost 

effective character will expand the saving and earnings of Indians 

at large. It will help in protecting our dear mother India 

environmental hazards.

BIO-LUMINESCENCE 

TO SOLVE POWER 

It is believed that Nature has solutions for all problems, 

including the power crisis that is currently rocking the 

country. In this project exhibit, an idea had been put 

forward to solve the power crisis with a solution of 

tapping the Bioluminescence that is available in plenty 

among the animals and plants for illumination purpose 

during night hours. 

Bioluminescence is the production and emission of light 

by living organisms, eg: Fireflies, Angler fishes, Jelly fish 

and Mushrooms etc., These creatures produce chemicals 

“Luciferin” and Luciferase (enzyme) for the emission of 

light. Using Recombinant DNA (rDNA) technology, the 

gene responsible for bioluminescent trait could be 

extracted from the bioluminescent organisms, and 

transferred into plants, so that, these bio-engineered 

transgenic plants can glow during night hours. These 

trees can be planted on roadways and highways so that 

they would emit natural light, thereby our Government's 

Electricity bill will be considerably saved. 

Why not these transgenic trees could replace street lights 

and bring about a revolution to combat power crisis. 

People may wonder and feel it as crazy but already an 

attempt had been made in 2007, by Edward A. Quinto, 

who produced a glowing Christmas tree. 

Now, everything & anything is possible with genetic 

engineering. So why can't we just make try and succeed. 


FIGHT GLOBAL WARMING WITH 

GENETICALLY ALTERED PLANTS 

Genetically modified plants are simply plants whose 

genetic material has been modified. The ability of plants 

as an absorber of Co will vary and it is determined by the 

2 

quality of chlorophyll. Besides increasing the efficiency of 

plants absorption of Co might be able to convert Co into 

2 2 

soil carbon and remain out of circulation for centuries. 

Samanea summons plant has a great ability to absorb Co . 

2 

By isolating the high absorbing Co gene (desired gene) 

2 

from its chlorophyll samanea summons plant and 

inserting into the Ever Green Vibarnum family using 

recombination DNA Technology. We can succeed in high 

absorption of Co 2 

A combination of such genomic improvement might 

enormously increase the amount of carbon that Vegetation 

naturally extracts from air. Such innovations might in 

combination, boost substantially the amount of carbon 

that vegetation naturally extracts from air.

GENERATING ELECTRICITY 

FROM PLANT 

Parthenium hysterophorus L, belonging to the family 

Asteraceae, the common weed, has inspired us to develop a 

power project. The sap, extracted from the whole plant, 

when connected with zinc and copper plate is found to 

generate electricity. “The weed is generally associated with 

'photophobic' skin allergies that cause an itching sensation 

when exposed to sunlight. The presence of Sodium 

Chloride and Silver nanoparticules formed the basis of our 

experiment. Both Silver and Chloride are good conductor of 

electricity. 

Sodium chloride improves ionic mobility during conducing 

electricity for better and constant power generation. The 

number of electrons and protons in the metals are equal but 

when the copper is placed in the parthenium extract it 

looses electron of the outer most orbit which are free to 

move. There is an imbalance arises between zinc and 

copper, so zinc gives its electrons to copper to maintain the 

number of electrons. Thus, there is a electron movement. 

Where there is a electron movement, there is electricity. 

Moreover, the following reactions make sure of continuous 

ionic movement in the cell. 

Silver nitrate which is present in parthenium extract reacts 

with copper to liberate silver, positive ions which is 

attracted by negative terminal zinc and deposited in the 

same. 

AgNO + Cu → Cu(NO ) + 2Ag 

2 3 2 

Sodium chloride reacts with the water giving negative ions 

chlorine which is deposited in the positive terminal copper. 

2Nacl + H O → 2 Na(OH) + Cl 

2 2 


GEO THERMAL POWER POINT 

Heat from the earth can be used as an energy source in many 

ways. This heat energy is known as Geo Thermal Energy. The 

temperature of the core is 6,000°c. Heat is conducted from the 

core to the surrounding rocks. The rocks melt and become 

magma. Heat is continuously produced there. The water 

trapped between the rocks gets heated up. Drilling the earth 

up to 10,000 meters and pumping the hot water up, 

extracting steam from it and there by running the turbine is 

the principle of generating the Geo Thermal Energy. 

The power generated is transmitted through transformer and 

sent to the places required. The cooled water is again injected 

into the earth, get heated up and the process is repeated. 

Advantages :- 

1. Uninterrupted electricity 

2. Unpolluted power generation 

3. Reduction of Global Warming 

4. The recycling or used water prevents the wastage of water 

5. The Geo thermal Energy is cost effective, reliable and 

sustainable 

Why do we need GEO THERMAL POWER ENERGY? 

In December 2011, over 300 million Indian citizens had no 

access to electricity. Is there not a need to balance the growth 

in demand for power with their availability. Ultimately, it is 

high time for us to think of generating electricity from the 

earth.

ELECTRICITY FROM RENEWABLE 

RESOURCES IN THE CHEAPEST WAR 

India currently suffers from a major shortage of electricity 

generation capacity. With electricity demand touching 

11,500 MW & generation remaining at 7500 MW, the Tamil 

Nadu is reeling under acute power shortage, prompting the 

government to resort to long hours of unscheduled power 

cuts. Especially my district, Virudhunagar face outages 

lasting over ten hours. Due to this shortage, I have 

undertaken this project. My project is “PRODUCTION OF 

ELECTRICITY FROM RENEWABLE RESOURCES IN THE 

CHEAPEST WAY”. 

My Solar bulb & Solar Cell :- 

I made a 40W solar bulb at the rate of just 50 paise with 

water bottle + water + bleaching powder alone. Using this, 

we can save & consume power in houses, offices, Godowns 

etc. in day time. This is the cheapest solar bulb that all 

levels of people can use in practical life. 

The solar cells & panels that I have seen in market was very 

expensive, So I made a solar cell using copper plates & salt 

water with that we can produce the current of 50µA in day 

time & 10 to 20 µA in night time. I think, this is the 

cheapest solar cell. 

Electricity from Ocean wave power:- 

We can generate electricity from ocean wave power using 

three basic systems. [i] Channel systems [ii] Float systems 

[iii] Oscillating water column system. In this I have 

selected the third one that uses the waves to compress air 

within a container & the mechanical power created, 

activates a generator which then drives a turbine. 


TO PROTECT ENVIRONMENT 

From our houses, daily wastage is coming. We classified 

wastes into two types. 1. Biodegradable and 2. Non – 

biodegradable waste. 

1. Biodegradable Waste : Generally the wastage produce 

methane gas (Ch4). It contains harmful power of fire. So, 

it affect the ozone layer. Hence we stored more wastage in 

cement tank. From that thank produced methane gas goes 

to boiler room through tube connection. There the 

methane gas is change the cool water into hot water and 

from the hot water, water vapour is produced. This water 

vapour goes to propeller room through another tube 

connection. It rotates the Dynamo and produce the 

electricity to all houses. 

Usage : 1. Electricity 2. To Prevent our environment and 

also ozone layer. 3. The used wastage is changed to bio – 

fertilizer for plants. 

2. Non-Biodegradable Waste : The plastics and other nonbiodegradable 

wastage items directly brought to the 

factory and melted to make a new materials. This 

recycling method is rescue the people and animals from 

death and lot of diseases. 

Usage : 1. To Prevent animals 2. To Prevent trees and soil 

fertility 3. To Prevent the people from diseases even 

cancer also.

AUTO TOILET REFRESHER 

Aim : Our important aim is to Avoid open Toilet 

Completely. 

Our country is developing in health. But particular 

percentage of people is taking in health awareness in 

developing countries our country is also trying ot achieve 

100% in health by allocating sufficient funds from the 

state and Central Government. Our Government has 

constructed modern toilets with electricity water and 

other modern facilities in all village and Town Panchayat, 

Municipalities and Corporations to achieve the above goal 

depending upon the population further the Government 

will construct more no of modern toilets and renovation 

works of damaged toilets are also under taken. 

But whether our people have been used properly… The 

only way for this is “ Auto Toilet Refresher “ is automatic 

cleaving of Toilet. The Public has the opportunity to use 

the modern toilet. It is not alone. The experiment is the 

best example for how the toilet is cleanness? This 

experiment is the important example to avoid the open 

toilet according to the proverb “ Cleanness brings Health” 

by using the Automatic Toilet Refresher. The Automatic 

Toilet Refresher can be very well used in all.

AUTOMATIC STREET LIGHT AND 

CONVERSION OF HUMAN ENERGY 

TO ELECTRICAL ENERGY 

1. Automatic Street Light: Today, the most of the work has 

been done with the help of the electrical power. So we are 

forced to save the power with this intention we have made 

Automatic Street light. Today we see in the village, as well 

as in the town, the street lights are not earning in the 

night, but in some place the lights are earning in the day 

time. So to avoid the waste of the power, we have made 

this. In this light the LDR the electrical power will be 

automatically switched off. When the solar light 

disappears the LDR will be switched on for this process 

human energy is not required. 

2. Conversion of human energy to electrical enerty : 

Today we can produce the electrical power in two 

methods. 1)Formal energy 2) Non-formal energy. NON- 

FORMAL ENERGY: i)Hydro – electrical power. ii)thermal 

electrical power iii) Atomic electrical power. FORMAL 

ENERGY : i)Wind electrical power ii)Solar light iii)Sea 

waves. By using this method. We get electrical power 

from the nature. Here we have made rotating entrance 

gate. We can fix this gate in bus stand, railway station, 

Schools and Colleges. By using method human energy is 

converted into electrical energy.

SOLAR UPS in Agricultural Irrigation and Household 

Works :- SOLAR UPS Consist of three main parts one is 

solar panel. Battery and UPS board. Solar panel produce 

current from the sunlight that effect is called photo 

electric effect. Battery saves solar current and ups board 

converts 12V DC current into 220V AC current. 

House hold uses :- In houses, we can use this solar ups to 

operate various electrical appliances such as bulbs, Mixer, 

Grinder, Fan at lower value of cost. 

Agricultural uses :- Now a days power cut is often accrue 

people uses Diesel to separate pump sets. So the rates of 

vegetables are very high affects peoples. But we use 

SOLAR power we can operate pump sets at free of cost 

and cultivate many vegetables through free irrigation. In 

this way, we can help National economical development. 

Other uses :- We can use this SOLAR current in factories, 

Road signals, at free of costs and free of pollution. 


This experiment based on friction force. Electric bulbs 

will be glowing without electricity connection. 

When we open or close the door the friction force is 

aeated. The force is changed into electric power. We used 

this power changed into sound and light energy. One 

motor and a dynamo is set up in the door. This motor is 

mol ate in one time the dynamo will be molate 30 times 

and electric power is produced.

SMOKE PRECIPITATION 

Smoke in air aerosol in which carbon particles are 

dispersed in air. In big industrial areas smoke is a 

nuisance, as it pollute the atmosphere and the carbon 

particles are injured to human health. 

The carbon particles are precepated and removed from 

smoke using Cottrell electrostatic preceptor. 

Smoke is passed in to a chamber filled with metallic knob 

charged to a very high positive potential. 

The negatively charged carbon particles are attracted 

towards the positive electrode. The electrode and loss 

into their charge and get deposited on the floor of the 

chamber. While the gas free from smoke goes out through 

the chimney. 

Uses : The precipited carbon is used as a by product for 

making Indigo Ink, black paints & carbon sheets. 


CARBON CAPTURE 

AND STORAGE 

The prevention method to prevent carbon from 

atmosphere is called carbon capture & storage. Removal 

of carbon from the power plant using chemical sol rent 

like ammine. Then it is compressed and removed from 

the ammine. 

Then it is injected to the underground below the cap rock 

to prevent mixing it with water which is domestically 

used by human. 

The carbon is mixed with the salty water on porous rock 

formation the it is stab and not moved to atmosphpere. 

Uses : Enhance all recovery, 

· Food 

· Beverages 

· Fire extinguisher 

· Wine making 

Carbonate formed at underground is used in the building 

consruction.

WIND MILL 

The concept of generation of electricity through wind mill 

is based on the law of non-destruction of energy and also 

faraday's law. According to law of Non-destruction of 

energy, energy can neither be created now destroyed. One 

levied of energy can be transformed into another kited of 

energy. 

Faraday's Law : Variations in magnetic flux will produce 

induced current in a conductor. 

Wind mills are installed at places where wind velocity is 

high. When the blades attached to the wind mill rotate, 

the dynamo produces electricity. Appropriate 

transformers could be used. 

There is no pollution to the environment this project 

could help generate electricity early within short time, 

electricity could be generated. 


SOLAR DRIER 

The slope and solar panels must be so positioned that sure 

rays fall on them save rays which fall on solar panel sets 

converted into electrical energy and converted in a wire 

which is connected to two fans. The fans in the drier 

rotate expeller air. 

The objects which are to be dried must be placed in the 

platter of driers and the drier must be closed. The hot air 

which is socked from the slope reaches the drier. In the 

drier, the air takes the moisture contained the objects 

placed a plates and goes out through the outlet. 

causes vacuum inside the drier. The hot air from the 

slope rushes in through tubes. The light energy charges 

into electrical energy and the electrical energy charges 

into machined energy which rotates the fans. The fans 

expels the air in the fan box. The air from the slope 

reaches the drier. This conations process makes the 

moisture present in the objects evaporate thus drying the 

objects.

MELTING MAN 

“Helath is Wealth”, “Healthy Persons are the Pillars of 

Wealthy Nation”, 

“Sound Mind is in Sound Body”. 

These Proverbs open the people mind to the possibilities 

of keeping our body in a Good condition. 

Alcoholism kills achievers and activate abbrevision. It is 

the root of all destructions. It slowly spoils the internal 

organs. Gradually destroys the entire body. Finally leads 

to death. 

Alcoholism is enhanced by ignorance, bad companions 

and recreational activities. Unless we are alert, it becomes 

the violent killer. The people those who are addicted not 

only loose their life but the entire family members life 

too. 

Alcoholism is like a fire which burn the dependents of the 

addicted persons. Being a good citizen avoid all unwanted 

usages. Let us utilize our Multi- dimensional power in a 

constructive way and create the luminescent World. 


Situation :- 

When a child fells into the a bore well 

Steps to rescue the child :- 

· Fix the steel rod on the ground near the bore well. 

· Allow the rope into the bore well hole. 

· See the condition of the child through the camera which 

fixed on the forceps. 

· After nearing the child tight the forceps. 

· Now the spongy material and the spring of the forceps 

help to hold the child.

INTEGRATED MOSQUITO 

CONTROL (BIO-CONTROL METHODS) 

Integrated Mosquito Control (Bio-Control Methods) 

Mosquito control is very difficult but must be attempted to 

not only rid of our surroundings of annoying bites but also 

to spread of mosquito borne health problems. In this 

project I have showed different methods of killing repelling 

and preventing mosquito infestation with the use of 

different from Bio Control Methods in flying and larval of 

mosquito in both indoors and outdoors using chemical 

products surely will make resistant strain and make our 

little enemy a 'Terrorist'. The different Bio control methods 

showed in this project are (i) Bats and Bat housed (How to 

attract Bat and make bat houses) (Butterfly bat can 

consume 600-1000 mosquitoes) (ii) Photo catalysis. 

Control mosquitoes in public area (mimic human breath, 

also purifies air) (iii) Bacillus thuringiensis. (Kills the larval 

form in a pond) (in the form of mosquito dunks) (iv) 

Toxorhynchites (Elephant mosquito) feeds on other 

mosquito larva especially Aides aegyrti. (v) Mosquito 

controlling fishes – (Many can live in low oxygenated 

water) (vi) Natural Predators varieties of birds like swallow 

wabler and Tadpole and drangonfly nymp and carnivorous 

plant. (vii) Mosquito control with plants – many plant such 

as catnip, lemon, grass, lavender, Rosemary can act as a 

powerful repellant. Catnip mosquito spray can be used in 

exposed skin. Children's dresses can be dipped and dried 

in diluted. Citronella (or) Rosemary oil will repell 

mosquito. To conclude – It is clear only Integrated 

Mosquito bio-control manages the population of mosquito 

to reduce their damage to human health economic and 

enjoyment and it is our duty to make the people to get 

aware of this methods and understand it to control pest 

(mosquito) population.

THREATS TO MARINE 

BIO-DIVERSITY 

This experiment is a set up that shows the threats to 

marine Bio diversity. Marine Bio diversity refers to the 

variety of life forms that are supported by the seas and 

oceans. The major threats to marine Bio diversity are 

caused by oil spills, Over fishing, Pollution and global 

warming oil spills. The major causes for oil spills are 

people's mistake or carelessness, Equipment breakdown, 

terrorists who cause oil spills, Illegal dumpers who dump 

crude oil into the oceans and natural disasters like 

hurricanes. The effects of oil spills are the death of birds 

and animals due to poisoning, hypothermia and some 

animals become endangered cleaning up process: 

Cleaning up is done by using vacuum trucks, high or low 

pressure hoses, using shovels and road equipments to 

collect oil. Oil consuming bacteria occur naturally in 

oceans that help to remove oil Prevention: Double hulling 

of ships helps to prevent oil spills. 

Marine conservation focuses on limiting human – caused 

damage to marine eco systems and restoring damaged eco 

systems. 

Humans are forewarned not against the use of nature of 

survival, but against the overuse and abuse. 


WOODEN GASIFIRE 

BURNER 

The name of the device is wooden gasifire burner. The 

fuel used in this burner is wooden materials from various 

plants. It is a thorn plant. It is available in large 

quantities in villages. It can be effectively used as a fuel. 

Since it contains 51 35% methane and being available in 

large quantities it can be used as an alternative fuel source 

for cooking. The device is made up of three separate parts 

the processing tank region and burnt. When it is burning 

carge amount of methane and carbon monoxide emits out 

through the outlet tube. The water molecule take the 

oxygen from carbon monoxide and changes to hydrogen 

molecule. It then becomes methane (CH ) and emits 

4 

through Burgher when methane mixes with air, it burns 

with nigh heat. By burning small quantity of this plant we 

can produce large amount of fuel. The time taken for this 

process is two hours and the money expenditure is just 

Rs.1.50. The raw materials for this process is available in 

our own country and we need not depend an other 

country.

Uses :- The people who come to tourist centers, may play 

(operate) the see-saw. Now water is pumped up through a 

bore well, water can be used for the plants in the centre 

(park). It com be used as drinking water It can be saved 

in a tank and used for all purpose. 

Thus, playing see-saw, water is pumped up and used for 

various purpose without power or expense. We can pump 

the water by play way. 


AUTOMATIC FIRE EXTINGUISHER 

Fire is a very good servants but a very bad master. As long 

as fire is under our control. It. Can create a lot of 

destructions when it goes out of our control. However 

despite the presence fire safety measures for occurrence of 

accidents oftentimes inevitable. 

In this project we use a thermal sensor receives the heat 

that inducted any where of the house and pass it to the 

relay. The relay switches on automatically the motor 

water and flow the water over the whole roof of house. At 

the same time the relay switch on the caution alarm to the 

awareness of the peoples. 

We can also use the mono ammonium phosphate fire 

extinguisher instead of the motor water pump for the 

purpose of concrete building.

PASSWORD DOOR LOCK 

This system is useful to modern world we can protect our 

home office etc. through this system. Now a days thieves 

easily broke the door lacks and stole our properties. 

Thieves easily broke locks made by any company. By 

using this system thieves and unknown persons. It is safe 

for us in future also. 

This system functions by giving correct password. If 

anyone gives wrong password the door will not open. 

This project is based on micro control unit system. When 

we give correct password number the power goes to 

driving unit and the door locks automatically. 


GENERATING POWER FROM 

AGRICULTURAL USAGE WATER 

· Generating power form agricultural usage water and 

house usage water. 

· Wherever we use the tap water . We can fix the turbine 

with dynamo to generate newer and store in battery. 

· To get generating newer form water tank. 

· To vary the generating depend upon their height. 

· To produce generating newer from falls. 

· By these process we stored newer in a storage battery for 

future use. 

In agriculture if we use 100% electrical energy in pumping 

process we will loss only 30% energy and we can 

regaining 70% electrical energy in this process.

DOUBLE SIDED FAN 

The greatest scientific achievement of the nineteenth 

century is the discovery of electricity. The twentieth 

century is making use of electricity. So extensively that it 

has almost changed the face of the earth. Tamil Nadu is 

Facing an acute electrical power crises. We demand that 

power be produced through any means and our demand 

be met somehow. Saving Electricity is cheaper and much 

safer. Keeping in mind such a power crisis, a double 

sided fan has been invented. Fans are largely used at 

home, office and in marriage halls. An ordinary table fan 

covers only 180 Degree. But this double sided fan cover 

360 degree and taking a single table fans electricity. So 

we can save electricity. 

Saving Electricity is cheaper and much Safer. 


UNMANNED RAILWAY GATE 

Topic: Avoid Accident at unmannerly Railway Gate. 

The Objective: To save life and smooth running of 

Railway. 

The Action Plan: The seasons installed in the Railway 

gate. These seasons can access a train coming from 3km 

on both side of the Railway gate. When the train comes 

the gate automatically closed and after the train crosses 

3km it will open and show the green signal. Their the 

vehicles can cross the Railway gate. 

Benefits: It is very easy to install. Expenses is has and it is

SAVING CHILD 

WITH BOREWELL 

When Children's are playing by mistake if a child had 

fallen into the well, the position of a child in the well can 

be observed with the help of this machine. model. By this 

model we can able to prevent the death of the child in the 

well. This model consists of a camera, which will be 

inserted into the hole of bore well and we can be visible 

on the monitor / TV. In this case we are using hooker to 

lift the child from the well. 


AUTOMATIC DIM AND DIPPER 

LIGHT CONTROL 

Aim :- Now a days the number of vehicles are increasing 

day by day. That is why accidents occurred. In during 

night times. The main reason for this, the vehicles, which 

are coming opposite side reflect the head lights 

powerfully. If we fix the unit in the vehicles it controls 

the head lights dim and dipper automatically. So the 

driving will be easy. 

Working Principle :- AC supply 230vac is given to step 

down transformer. It reduces 230 v to 12 vac. The 12 vac 

is given to Bridge rectifier. It converts 12 vac as 12 vdc. 

In this circuit a regulator. IC (7805) is also used. The 

capacitors are used to boost the voltage. In this circuit 

LDR (Light Depending resistor) is used as sensor.

TIDAL ENERGY (TO PRODUCED 

ELECTRICITY FROM THE TIDAL ENERGY) 

Tidal Energy: Ocean Has Produce two types of energy Thermal energy 

form the sun heat and mechanical energy from the Tides and waves. 

Tides are generated through a cpmbination of forces exerted by the 

gravitational pull of the sun and the moon and the rotation of the 

earth. The relative motion of the three bodies (Sun, Moon & Earth) 

produces different tidal cycles which affect the range of the tides. Ind 

addition the tidal range is Increased substantially by local effects such 

as shelving, funneling, reflection and resonance. Energy can be 

extracted from tides by creating a reservoir or basin behind a barrage 

and then passing tidal waters through turbines in the barrage to 

generate electricity to save power house and distribute the public use. 

Tidal energy is extremely site specific requires mean favorable to 

pographical conditions such as estuaries or certain types of bays in 

order to bring down costs of dams etc. Since India is surrounded by 

sea on three sides its potential to harness tidal energy has been 

recognized by the government of India. 

Tidal Barrage : A way of converting the energy of tides in to electric 

power. When the tide goes in and out the water flows through tunnels 

in the barrage. The ebb and flow of the tides can be used to turn a 

turbine or it can be used to push air through a pipe which then turns a 

turbine. 

This process effective than the thermal power, atomic power, sun 

power and wind power because more density of water. 

Potential of Tidal Energy in India : The most attractive locations are 

the gulf of cambay and the gulf of kachchh on the west coast we here 

the maximum tidal range is 11 m and 8 m. the ganga delta in the 

sunder bans in west Bengal also has good locations for the small scale 

tidal power development. The maximum tidal range in sunder bans is 

approximately 5m. the identified economics tidal power potential in 

India is of the order about 7000 mw in the gulf of cambay about 1200 

mw in the gulf of kanchchh and less than 100 mw in sundarbons. 

Foreign Tidal Energy Center : The foreign country of Uk, USA, France 

and Canada are used floating device method and tapered channel 

wave power to produced electricity from the tidal energy. 

Advantages : 1. Pollution Control, 2. Renewable energy 3. Effectively 

than the other method because more density of water. 4. Need not 

fuel 

Disadvantage : Expensive Maintained the Building. 


CORAL LODGE BIOGAS 

Human excreta based biogas plant : Energy equivalence 

of biogas. 

A thousand cft (30cum) of biogas (Produced from 1000 

users of a toilet complex) is equivalent to 

· 600 cft of Natural gas 

· 6.4 gallons of butane, 5.2 gallons of gasoline, 

· 4.6 gallons of diesel oil. 

Advantages: Contains good plant nutrients – N.P.K and 

micronutrients for plants. 

The reuse of human excreta may gain acceptance even in 

societies having religious and cultural taboos associated 

with it as the valves do change with time, advancement of 

education and awareness among the people.

ECO-FRIENDLY ENVIRONMENT 

Plastics are now unavoidable in the government. It has 

polluted the would a lot. So to seek a solution, some 

methods have been introduced. On the other hand, roads 

too are not proper. They are not able to withstand a single 

rain also. Both of these problems lead to the invention of 

plastic roads. Plastics are mixed with bitumen to get 

plastic roads. Plastic roads have a lot of benefit. (i) Low 

cost (ii) Simple technology (iii) Dow ring of road strength 

(iv) Zero maintenance. Some salient features of plastic 

roads are :- (i) Easy narcoses without any new machinery 

(ii) Simple process without any industry involvement (iii) 

Use of lesser % of bitumen (iv) Use of plastic waste for a 

safe and eco- friendly process (v) No evolution of any 

toxic gases like dioxin. Specifications for waste plastics:- 

(i) Films (Carry bags, cups) thickness up to 60 micron (ii) 

Hard foams (Ps) (iii) Soft foams (PE, PP) (iv) dominated 

plastics (v) Packing materials used for biscuits, 

Chocolates, etc… Poly Vinyl Chloride (PVC) and flux 

sheets should not be used in any case. Some facts:- Salem 

is the first place in the whole world to lay plastic roads. 

Some of the states which lay plastic roads :- (i) Tamil 

Nadu (ii) Andhra Pradesh (iii) Kerala (iv) Goa (v) 

Pondicherry. 


POLLUTION (THREE TYPES 

OF POLLUTION) 

Pollution and Prevention 

The relief of harmful substances most by resulting from 

human activity into the environment called 'POLLUTION'. 

There are Three types of pollution. 

I. Air Pollution:- Smoke which comes from factories, aero 

planes vehicles. Refrigerator the air getting polluted which 

spoils the atmosphere. Due to this 'Ozone' effect by hole. 

Effects:- People affect many disease like eyes burning and 

skin disease. 

Prevention:- (1) Avoid wastage oil (2) Reduce the vehicles. 

(3) Planting more trees. 

II. Water Pollution :- Waste and chemical water comes from 

the industries, hospitals, office and stagnation of water which 

makes the water pollution. 

Effects :- Stagnation of water due to the stinking disease like 

maleria fever affect & the people. 

Prevention :- Waste water can be purified or reneove the 

wastage and send the cleaning place. 

III. Land Pollution :- More manere pesticides Plastics, 

animals wastage Handloom waste water (colour) industries 

water makes the land pollution. 

Effect :- The soil lose its strength plants and trees cannot 

grow for long time and also soil erosion. 

Prevention :- Reduce the use of chemicals and maneres 

prevent cutting the trees. 

Avoid Insecticide :- To live happy in the world we have to 

follow there rules in future and make the land green land.

TERMO COMPOSER 

This experiment focuses on manure processing using both 

termites cellulose and liquefied cow dung. Termites 

usually secret cellulose and this cellulose makes the 

wasted / used paper cups to become a good compost 

manure used paper cups are found in plenty in and 

around our houses and towns. This process by cellulose 

making the paper cups into manure takes a long time. 

To make the manure process faster than the time taken 

this experiment has a pot containing wasted paper cups 

into which cellulose through one tube and liquefied cow 

dung on the other tube is sent. The manure process takes 

place using bothe cellulose and liquefied cow dung. The 

duration taken for the manure is shorter than the termites 

cellulose without the cow dung. 


ZERO – CARBON HOUSE 

The zero carbon home will fully integrate with the family 

who live in it and ever physically adapt to suit their 

changing needs and life style. What's more energy Aspire 

living's Zero carbon Home would not look out of place in 

any neighborhood, and all materials are readily available. 

Make the most of its location for a warmth from the 

Winter, Sun, Cooling breezes in summer and views all

STREET LIGHT 

AUTOMATIC ON/OFF 

This project is designed by following blocks : 

LDR, Comparator, Relay and Lighting System 

The system consists power supply unit, lighting system, 

LDR, Comparator and a Relay. The LDR is a light 

detecting resistor, which output voltage varies depends on 

the environmental light, it is connected with comparator 

for sends low voltage and input voltage, when the sun 

light is dark, the LDR sends low voltage to the comparator, 

so the reference voltage and LDR output voltage are not 

matched with each other, then the comparator triggers a 

high puls from its output pin, this is given to the relay 

driver circuit for ON the street light. So the two reference 

are onual its off.

AVOID FIRE ACCIDENT IN TRAIN 

USING SENSOR 

Principle : Thermostat is used as a fire sensor. This 

sensor has two strips. One strip is thermostat. It is mode 

of two metals or alloys. Due to different metals or alloys. 

When heat is given this strip bends instead of elongating. 

Working : First switch 1 is closed current is ready to flow 

through the circuit. But the thermostat does not connect 

to the another strip. So no current is flowing. When 

there is a fire near the thermostat arrangement due to heat 

the thermostat strip bends and touches the other strip. So 

the circuit is closed not current is flowing through circuit. 

The alarm circuit works and we hear the alarm sound 

from the speaker. 

Position to fix this arrangement : This sensor 

arrangement is fixed in the train compartment. Wherever 

there is possible for fire accident. [window, coach 

entrance, in the Toilet etc]. multiple sensors are fixed in 

various compartments, and they are connected to main 

battery in parallel circuits. 

If the speaker is connected parallel to other speakers, we 

get alarm in each coach and may alert ourselves. 

Uses of this project : 1. Save the passenger from major fire 

accident. 

Maintains life security and peaceful and happy journey. 


—Three process are taking part in the mobile operated 

vehicle. 

—In this process no fuel or electricity is used. Only solar 

energy is used to run the vehicle. 

—3 G mobile is used to control the directions of the 

vehicle. It can be directed from any any where in the 

world. 

—Bomb indicator is used with the help of the magnet, 

which will be helpful to findout any bombs by making a 

peep sound in the way. 

—With the help of this vehicle, the handicapped persons 

also travel from place to place. 

—If one more 3 G mobile is used in the system, it is visible 

to locate the vehicle at any distant place.

SMART DOMESTIC 

SWITCH CONTROL 

SMART DOMESTIC SWITH CONTROL 

This is an innovative switching system made specially for 

the old age and bed – ridden people. Using IR remote 

control they can put on or off any type of home 

appliances, even the electric motor behind the house. 

In this model, the 230 V Ac current is reduced using 1 A 

step down transformer to 12V DC. So that the Microcontroller 

works. The IR rays coming from the remote is 

gained by an IR sensor. The IR sensor sends the signal to 

the Micro-controler. So, this Mc commands the relays to 

distribute the current to the concerned appliances. 

This is compact and are affordable even by the middle 

class people.

(ii) NATURAL AND ALTERNATIVE REFRIGERANTS 

MAKING MOULDING MODELS USING WASTE PAPERS 

Introduction :- “Using waste and making wealth is an Art” paper 

recycling is the process of turning waste paper into new paper 

products. In this project an attempt has been made to made use 

of the post consumer waste. (PCW) papers. 

Procedure :- PCW papers are collected and cut into small pieces 

and dip in fresh warm water for sometimes. Grind well with 

mechanical means to get paper pulp. Put the wet pulp on the 

sleeve. Spread a plastic paper on the sleeve over the pulp. Excess 

water will be absorbed by using sponge. Leave it to dry under 

sunlight paper boards will be made. 

Wet paper pulp will be made as various items like toys, 

decorative materials etc by putting the wet pulp in different 

moulds. 

NATURAL AND ALTERNATIVE REFRIGERANTS 

Introduction:- Refrigerants Naturally is a Global initiative of 

companies committed to combat climate change and ozone layer 

depletion by substituting harmful fluorinated – gases with 

Natural refrigerants. In this projects refrigeration is done. 

Procedure :- A small earthen pot is put inside the bigger one, 

The gap between the two walls to be filled with river sand, 

which will be kept wet. The inner part will be used as the 

container part for refrigerants. The pot mouth will be convered 

by dry cotton cloth. 

Conclusion :- It is Natural refrigeration without any 

environmental pollution and electricity. Now a days 

Government encourages business and industries to work 

together to eliminate 'F' Gases completely it is economically 

cheapest refrigeration process to useful to preserve vegetables, 

fruits, etc. in small and large scale for an week.

GT LEAVES AS BIO-FILTERS IN 

STONE CRUSHER PLANTS 

Stone crushers produce silica dust in large amount and 

pollutes environment. Pollution control board fixed 

filters to control the dust. Lesser than 10 microns size 

silica particles cannot be filtered through these filters. 

This particles are carcinogenic which cause Respiratory 

diseases like Asthuma Lung Cancer and Bronchitis. At 

the same time silica dust accumulates on the plant leaves 

and causes chlorosis, affects photosynthesis. 

To solve these problem we planned to give solution with 

the help of Bio technology. DNA Technology helps us to 

transfer the gene form one plant to another. Dr.Mithra 

and etal Biotechnologist identified the sticky silica dust 

dissolving gene is present in the Elephants Ear plants 

especially in colocasiaantiquorum and esculent a species 

and saved in the gene bank. We focused our project to 

transfer Hind III leaves 5 'and Kpn I leaves 3' having 

sticky charter gene transfer to Tectonic grand is (Teak 

plant). The new gene transferred Teak plant is enough to 

capturer and dissolve the carcinogen particles and 

control the environment, and reduce the hazards to 

people. 


Electricity produce from Home Wastage 

Aim of Project :- Today's Important problems scarcity of 

electricity. 

Thermal Power :- There is a scarcity of coal to produce 

thermal power. Also it affects environment. 

Hydropower :- When there is no water for drinking and 

agricultural. It is not at all possible to produce 

hydropower from water source not only in future even at 

present also. 

Nuclear Power :- As we produce electricity from atomic 

energy the dangerous atomic radiation which comes out 

while power producing affects men kind is known fact. 

Wind Power Generation :- Though we get electricity from 

wind power it is not possible through out the year. 

Environment is being affected and polluted by home 

wastages, the home wastage should not be wasted. By the 

way using the wastage to produce electricity, we can car 

tail the pollution to the environment also.

SCHOOL GETTING UNINTERRUPTED 

SUPPLY OF WATER 

As per the guidance of our Headmistress and BRTE I have 

designed and automatic electric circuit which operates an 

electric motor to pump water from well to overhead tank. 

With the help of PVC pipes and plastic container I have 

made a model of overhead tank. I have connected the 

input signals of electric circuit on the upper part of 

overhead fowl. 

When the tank gets filled with water, water acts as 

conductor of electricity. With the basic principle the 

input signals goes to the electric circuit resulting stops the 

electric motor respectively. Outcome of the above wastage 

of water due of overflow of tank is avoided simultaneously 

saves electricity. 

After consumption of water when the level goes down the 

connection between input points gets disconnected and 

the electric motor starts automatically until tanks filled 

again. 

With the above implementation our school's overhead 

tank found filled with full of water always which enable 

us to get uninterrupted supply of water to maintain health 

and hygienic measures to the students in our school.

ECO-GREEN EVAPORATOR 

Eco Green Evaporator 

Treating effluents in the dyeing units making a great 

problem usually 80 to 90 % of the effluents are treated 

using the Reverse Osmosis (RO) system. Handling the 

remaining 10 to 20 % is a major problem. The final 

evaporation requires more firewood and mechanical 

evaporators could also become useless and complicated 

due to sedimentation of salts and also needed periodical 

maintenance. 

In this method 30 feet high wooden frames are 

established and thorny shrubs are sprayed on its wooden 

compartments. The effluent are sprayed on the over head 

of the wooden frames. 

The effluents would percolate through the “Velikathan” 

and evaporate. The interaction between air and effluents 

drops made to evaporate. We increase the surface area 

and by wind power and heat energy. 

The comparison to the existing system, the new method 

(graduation) is cost effective (One fifth) and environment 

friendly. 

As much lakh litres of water with 30,000 TDS PPM of salt 

could then be converted into solid waste using a 

crystaliser in a chilling unit, thus attaining Zero Liquid 

Disposal (ZLD). 


FIRE EXTINGUISHER 

This fire extinguisher is used to avoid fire accidents. The 

transformer is connected to the current. It changes 240 

watts current to 12v. At home the increase of temperature 

is noticed by the sensor. So the relay switch is switched 

on, with the help of the I.C. and a sound is produced. 

This sound switches on the motor which is kept under 

water. This water is showered by the shower and the 

temperature is suddenly reduced. 

Places like Factories, houses, offices, gas felling Places 

where there is sudden leakage of fire, it acts as a fire 

extinguisher and tries to put off the fire and gives safety.

PROTO TYPE HUMAN 

TRANSPORT VEHICLE FOR 

UNKNOWN TERRAINS 

Principle : The project is based on the principle of shifting 

of the 'Centre of Gravity'. 

The robot possesses the climbing ability which is given by 

the sequential rising of the center of gravity (CG) provided 

by the consecutive action of the wheels and movement of 

the four arms. It has the following characteristics: 

a. Adaptation and smooth movement on the uneven 

terrains. 

b. Passing obstacles of different sizes. 

c. Tip over/back stability. 

d. Minimizing motor energy consumption while 

decreasing the maximum of instantaneous power. 

e. Ability to come out of holes and continue motion even 

when problems occur for individual wheels. 

Utility : 

1. This prototype can be a perfect intelligent spying and 

mine detecting machine. In spying operations a person 

may encounter difficulties in properly seeking the 

details of the area, especially in unstructured 

environment. Therefore using a robot for searching the 

enemies as well as describing the best path to reach 

the enemy, decreases the risk of a spying operation. 

2. In rescue operations it will increase the accuracy, 

safety, and the speed of a rescue operation as it can 

scale very easily rough terrains. 

3. We see it as a perfect human carrier for mission to 

Mars because of its capability to encounter and scale 

rough and unstructured environment and its 

characteristic to utilized minimum power to generate 

maximum torque.

saving during the post earthquake situation. Through these 

equipments, we can extend help in the natural disaster prone 

areas within short span of time. 

Thus, on the basis of the principles of physics, geology, geoscience, 

geography and architecture, we can create such 

structures which can nullify the effect of earthquake up to 30%to 

40% such basic principles of science if we put into practice in an 

innovative way, can prove life- saving during the times of natural 

disaster.

GENERATION OF ELECTRICITY : 

THROUGH MOTION OF TRAINS 

Principle : 

Trains generally run on electricity these days. Trains 

consume electricity but they can also be a potential source 

of generation of electricity as they run on a very HIGH 

SPEED. 

Working : 

Windmills connected to Turbines can produce electricity 

which can be used for other purposes. Kinetic energy of 

trains would be employed to run the windmills and 

Turbines, which can be stored for use. 

Utility :

Principle : Solar pyrolysis is the process of decomposition 

of complex carbon compounds in absence of oxygen by 

solar heat. Pyrolysis of organic substances produces gas 

and leaves a solid residue richer carbon content, char. The 

process is used heavily in chemical industry to produce 

charcoal, activated carbon, methanol and other chemicals. 

The syngas produced is a (flammable mixture of carbon 

monoxide gas, H and traces of CO ). Char can be recycled 

2 2 

as a fertilizer. Methane gas is also produced which on 

combination with water again produces syngas. Excess of 

CO can be stored to make for fire extinguisher. 

2 

Working : The bio-waste is put in a air tight jar which is 

attached to a outlet for gases. The gases will go to the 

refinery chamber where different gases are separated for 

different uses. For the decomposition of the bio-waste we 

focus convex lens on the jar which is placed in a water 

bath to avoid excess of heat and pressure. From the 

refinery chamber, we attach a Bunsen burner to check the 

flammability of syngas.

GLUCOSE ALARM 

Principle : 

When the glucose is about to finish, the bottle moves up 

and touches the strips of iron, the electric circuit is 

completed and alarm starts working and the bulb also 

starts glowing. 

Working and Utility of the Project : 

There are still many problems in the modern world which 

need to be solved or taken care of. One of these is the 

problem of administering glucose to a patient. When the 

glucose is administered to a patient, the nurse or the 

doctor has to remain alert to change the drip or to stop the 

drip before the glucose is about to finish. 

If the doctor or nurse doesn't do so, the air will be sucked 

and blood of patient may be reversed. It may be dangerous 

for the patient, So in this model, I have tried to improve 

this drawback, In this model, when the glucose in the 

bottle is about to finish, an alarm starts working and bulb 

also starts glowing. The doctor or nurse changes the bottle 

of glucose. Through my model, I want to convey this to 

every hospital that they should install such an alarm 

(Glucose Alarm) so that the life of the patient is not put to 

risk. It also saves the time of doctors and nurses because 

they don't have to check the glucose level time and again.

MAGNETIC LEVITATING TRAIN 

Maglev (derived from magnetic levitation) is a system of 

transportation that uses magnetic levitation to suspend guide 

and propel vehicles with magnets rather than using 

mechanical methods. With maglev a vehicle in levitated a 

short distance away from a guide away using magnets to 

create both lift and thirst. Maglev vehicles are claimed to 

move more smoothly and quietly and to require less 

maintenance than wheeled mass transit system. It is claimed 

that non reliance on friction also means that acceleration and 

deceleration can far surpass that of existing forms of 

transport. The power needed for levitation is not a 

particularly large percentage of the overall energy 

consumption. The highest recreated speed of a maglev train 

is 581km/h (361mph) achieved in Japan 

Technology: The term maglev refers not only to the vehicles 

but to the railway system as well, specially designed for 

magnetic levitation and propulsion. All operational 

implementation of maglev technology have had minimal 

overlap with wheeled train technology and have not been 

compatible with conventional existing infrastructure, these 

maglev system must be designed as complete transport 

systems. 

There are two particularly notable types of maglev 

technology. 

—For Electro Magnetic Suspension (EMS) electronically 

controlled electro magnets in the train attract it to a 

magnetically conductive track. 

— Electrodynamic Suspension: Uses super conducting 

electromagnets or strong permanent magnets which create a 

magnetic field that induces currents in nearby metallic 

conductors when there is relative movement which pushes 

and pulls the train towards the designed levitation position 

on the guide way.

Exhibition 

& Project 


The aim of this project is to put forward some revolutionary 

concepts that will fulfill the present and future vehicle needs for a 

better, green and eco friendly transportation. It is a design of a 

hybrid eco friendly car with new features to fulfill the present and 

future vehicle needs. 

Scientific Principles: Electrolysis, Pascal's Law, Pressure and 

Fluids, Electricity Generation, Methods/procedure, Fuel-hydrogen 

Gas. 

The water input is distilled. The vapors are condensed & collected 

in another container with an acid funnel above. The acid funnel 

provides drops of acid whenever required to acidify water for 

electrolysis using graphite electrodes which provides hydrogen gas 

for fuel. 

Dynamo generation of electricity and application : 

Transmission 

Whenever the driver puts reverse transmission, a dynamo 

connected to the reverse gear, produces electricity for the light and 

sound effect symbolizing its reverse motion. 

Weight Balancing inlet and aerodynamic spoilers 

Speedy cars have wind inlets at the back for balancing weight and 

providing required force downwards to make it more aero 

dynamic. These inlets can be used for electricity generation. 

Real life applications 

NASA used hydrogen as fuel in the first spacecraft. Japanese 

Institute Of Space And Astronautical Science (ISAS), built the 

RVT-6 spacecraft pictured above. The RVT-6 is a prototype for a 

commercial line of spacecraft that is powered by a hydrogenfuelled 

rocket engine.

Piezoelectricity is electrical energy produced from 

mechanical pressure (including motions such as 

walking). When pressure is applied to an object, a 

negative charge is produced on the expanded side and a 

positive charge on the compressed side. Once the pressure 

is relieved, electrical current flows across the material. 

Let's look at how the principle works in a motion such as 

walking. A single footstep causes pressure when the foot 

hits the floor. When the flooring is engineered with 

piezoelectric technology, the electrical charge produced by 

that pressure is captured by floor sensors, converted to an 

electrical charge by piezo materials (usually in the form of 

crystals or ceramics), rectified and then stored and used as 

a power source. 

I am proposing the idea of installing piezoelectric flooring 

in urban areas. Dubbed "Piezets", the idea is to install a 

flooring system that would take advantage of piezoelectric 

principles by harvesting power from footsteps in crowded 

places such as train stations, malls, concerts and 

anywhere where large groups of people move. The key is 

the crowd: One footstep can only provide enough 

electrical current to light one 0.10 watt LED for one third 

of a second, but the greater the number of people walking 

across the piezoelectric floor, the greater amounts of 

power produced. It's not beyond the realm of possibility -- 

approximately 28,500 footsteps generate energy to power a 

train . Imagine what the combined power of commuters' 

footsteps during rush hour could do.

COMMUNICATION 

The need for communication has been around since the 

beginning of humanity. It has seen tremendous 

development since the end of 19th century as technology 

has improved. 

Telephone - Advances in technology have allowed for 

transition from landlines to wireless & also integration 

with video & internet. 

Radio - In 1906, the first radio transmitter enabled music 

& speech to be broadcast to wide audience. 

Television - It was introduced in 1946 & further become 

predominant source of communication to audience and 

brought about huge change in the political, cultural 

scenario forever. 

Military Communication - Satellites are used for modern 

tactical communication in guidance of missiles from 

weapon control platforms and remote target tracking 

systems. 

Wireless Communication - It means transferring 

information without wires is used for security purpose, 

long range guidance system, ATC communication with air 

crafts, cellular phones, modems, Wi-Fi etc... it is the 

backbone of satellite technology & also enables 

communication with Submarines. 

Internet - The creation of internet allowed computer 

networks around the globe to be networked with each 

other giving everybody access to most powerful 

information resource. E-mails, chats, video-conferencing 

have broadcast horizons of communication. 

The worlds as we see today will be totally different in 

another 10 years times with the power of communication 

technology.

Oceans cover almost three fourth part of the earth's 

surface. The oceans water, the air above the oceans and 

the land beneath them contains enormous energy 

resources. This model shows how oceans can fulfill the 

basic needs of energy, water, food for the survival of 

human being. 

Energy: This model shows three ways of generating 

electricity from the tides namely, Tidal Stream Generator, 

Barrage and a Reef and also demonstrates two ways of 

producing electricity from the waves namely, i-wave and 

Oyster. We are suggesting i-wave farm which will harness 

energy not only from the waves but also from the strong 

wind currents. 

Water: Fresh water is only 2.75% of the total water 

available on earth, so it is important to obtain potable 

water from sea. The process of Desalination is depicted in 

this model. We are suggesting 'Green House Salt Framing', 

a new way of obtaining potable water by building a green 

house over a salt farm. This water can be utilized for 

agriculture. 

Food: Seawater Farming proposes a radically different 

method of agriculture that does not depend on freshwater 

and thus relieves the existing constraint on the current 

freshwater body. The entire process of channelizing sea 

water from sea to fish farms and then to mangrove farms, 

is shown through the model. Water evaporation from vaststretches 

of seawater farm will increase humidity and 

rainfalls, bringing desirable conditions for other economic 

activities. 

The long-term objective of this model is to transform the 

coastal region through sustainable and natural means, 

making them self reliant or may be surplus in terms of 

energy, fresh water and food.

TSUNAMI ALERT AND 

WATER REDUCTION BY 

ELECTROLYSIS (T.A.W.R.E.L.) 

T.A.W.R.E.L. is a simple yet innovative system which 

starts by giving an alarm on sensing entraordinary water 

levels and later starting on an electrolysis process to 

reduce water quantity sufficiently to control the damage. 

The alarms are placed at different levels so that workers 

can swing into action immediately. The alarm and 

electrolysis system is backed up by D.G. supply (Diesel 

generating sets), capacitor banks, light houses, investors, 

power houses so that the power failures are taken care of 

and electrolysis and alarm systems continue without any 

break. 

Technology : True leads, running from the terminals of the 

battery, are placed in a cup of water with a quantity of 

electrolyte to establish conductivity in the solution. Using 

NaCl (table salt) in an electrolyte solution results in 

chlorine gas rather than oxygen due to a competing halfreaction. 

With the correct electrodes and correct 

electrolyte, hydrogen and oxygen gases will stream from 

the oppositely charged electrodes. Oxygen will collect at 

the anode and hydrogen will collect at the cathode. 

In real electrolysis systems, a different solution is used, 

and higher levels of electricity help to split the water 

molecules into hydrogen & oxygen, without the secondary 

action. 

Applications : About four percent of hydrogen gas 

produced worldwide is created by electrolysis. The 

majority of this hydrogen produced through of chlorine. 

This is a prime example of a competing side reaction. The 

hydrogen produced from this process is either burned, 

used for the production of speciality chemicals, or various 

other small-scale applications. The oxygen is used in 

hospitals, factories, for gas cutting and other application 

areas. It is also used in mines.

There are mainly 3 steps for Extracting Oil from Micro 

Algae: 

Cultivation: Algae cultivation can be achieved in two 

ways: a) Open Ponds b) Photo Bio Reactors. Open ponds 

are generally shallow ponds also called Raceway Ponds in 

which a motorized paddle rotates water to enable algae to 

be collected at the surface and removed periodically. A 

Photo Bio Reactor is a closed equipment which provides a 

controlled environment and enables high productivity of 

algae. All growth requirements of algae such as CO2, 

Water, Temperature, and Exposure to Light are introduced 

into the system and controlled according to requirement. 

Harvesting: The term harvesting refers to concentration of 

diluted algae suspension until a thick paste is obtained. 

This includes several techniques like Settling or 

Floatation, Centrifugation and Filtration. These 

techniques are aided by Cell Flocculation through 

addition of chemicals. 

Extraction: Bio diesel from algae can be extracted by 

Mechanical as well as Chemical methods. The oil gets 

separated in Gravity Clarifier. 

In short, we can say that the way fossil fuels are becoming 

scarce and the pollution they create, it is high time we 

cross over to clean energy resources. Bio fuels are the new 

way ahead and algae with their proven benefits are 

certainly the fuels of future.

GOOD AND BAD CHOLESTROL 

In India, millions of people die due to heart attack and the 

main cause is the blockage of arteries that supply Oxygen 

to heart and the reason behind it is bad cholestrol. 

The model/exhibit represent the presence of good and bad 

cholestrol present in our body. Bad cholestrol or low 

density lipo protein (LDL) is the main cause of formation 

of plaque in arteries and blockage of coronory arteries 

leading to heart attack, while good cholestrol or high 

density lipo protein (HDL) helps in eliminating bad 

cholestrol from our body. 

The exhibit has three parts: 

(1) First part displays the structure and function of heart 

and the role of cholestrol in our body, how cholestrol 

enters in our body and effect of good and bad 

cholestrol on arteries. 

(2) Second part is experimental set up to determine which 

oil (brand) is best for heart and contains less saturated 

fat. A comparative chart displays the saturated and 

unsaturated fat present in different oil brand used for 

cooking. 

(3) Third part of the model shows the healthy food for 

heart, food and herb that increases good cholestrol 

and decreases the bad cholestrol in our body. 

Scientific principle behind the presence of saturated and 

unsaturated fat present in different oil is the time required 

for Iodine to loose its colour from oil solution. More time 

required indicates more saturated fat in oil. Canola Oil is 

the best oil as per our findings. 

Healthy heart requires healthy food and regular exercise, 

some food and herbs helps in increasing the functioning 

of heart while exercise give strength to our heart.

Introduction:- Due to the increase in population, the 

pollution is increasing, energy resources are decreasing. 

To overcome this problem of energy crisis, this model is 

made to remain cool in hot weather & remain hot in cool 

weather. 

Principle:- The model works on the principle of difference 

in temperature above the earth and under the earth. When 

the temperature above the earth is high at that time. when 

temperature under the earth is low depending upon the 

location of place on earth. 

Working:- In this model ducts are placed in the zigzag 

manner under the earth which are connected to the cool 

house. 

—The exhaust fan of cool house throws air in the above 

rooms. 

—The exhaust of above rooms throws hot air to the duct 

again. 

—The ducts contain holes which allows the exchange of 

fresh air also.
