STRAIN VIEWER 

Function :- In consists of two polarizing filters polarize and anlyser. Analyzer can 

be rotated relative to other in between the two filters in where you put the object whose 

strains is to be measured. The strain in the object will affect the polarization and gives 

the firings pattern of colors. 

When the polariser and analyzer are arranged so that their directions are perpendicular 

to each other , very little (idle Zero) Light passes through both filters . If the analyzer is 

rotated a little bit, then some light will get through the polarize. Glass, which has to be 

tested for strains, is placed between analyzer and polariser now rotated the analyzer so 

that we can observe the light which passers through polariser and glass object. 

It the galls object has stains then we can ob serve fringe pattern of colors in that area. 

Stainless galls have no firings pattern of colors. 

Uses :- Strain viewer is very useful optical instrument, which can be used for strain 

observations in somewhat light based products of industries. We can examine glass, 

plastics, salt, ruby for strains using Strain viewer.

be known. Which creates many problems in the investigation. The Black Box stores 

and saves all the data like speed, fuel, date, day, time and temperature during the 

accident which proves to be very important in further investigation, disbursement of 

insurance amount etc. 

It consists of as witch in the front which alerts the system a micro- controller to control 

and process the system, an analog to Digital converter (ADC) to convert analog signals 

into digital, etc. The Black Box helps to send all the data to an installed cell number 

during accident. Even if damaged, it can provide the data by an inserted password. 

The sensors behind the vehicle transmits continuous electric rays which are reflected 

back to a receiver when an other vehicle comes near the car. It creates a certain sound 

which makes the driver alert. Thus the accident can be prevented. Thus the Black Box 

helps to know the reason of the accident and to prevent it.

TSUNAMI RESISTANCE TECHNOLOGY 

•Tsunami is a wave train or series of waves generated, by impulsive disturbance 

that vertically displaces the water column in a water body. •Most Tsunami are caused 

by earthquakes generated in a subduction zone, an area where an oceanic plate is being 

forced down into the mantle by plate tectonic forces. •The friction between the sub 

ducting plate and the overriding plate is enormous. 

•This friction prevents a slow and steady rate of subduction and instead the two plates 

become “ stuck ”. •The result is an accumulation of energy very similar to the energy 

stored in a compressed spring. •Energy can accumulate in the overriding plate over a 

long period of time- decades or even centuries. •Most frequently in the Pacific ocean, 

but are a global phenomenon, are possible wherever large bodies of water are found, 

where they can be caused by landslides •Our aim of project is to reduce the intensity 

and loss occur due to Tsunami by using technology and planned development in 

coastal areas. 

Tsunami can be reduced by : 1.Tsunami detector and seismograph. 2.Using tsunami 

breakers. 3.Proper planned development at coastal areas. 4.Tsunami resisting and 

proof buildings and houses. 5.Plantation along the coastal areas. 6.Rehabilitation in 

coastal areas. 7.Construction of safer places. 

8.Creating awareness among people.

railway tract many more crossings are no gate to control the traffic. So their are many 

an accident on the railway crossing and died many people. In my project there are 

vehicle no accident on railway crossing and save man power and money. 

In project :- 1) When the train coming from about 5 km from the crossing gate, ring 

the sairon and on the red light. The motor driver will be alert. He stop his vehicle 2)If 

the train coming from about 2 km from the crossing gate ,the gate will be shut down 

atomatically . And vehicle will safe. 3) If the train the crossing gate the gate will be 

open atomatically and start the traffic on the road. 

4) If there are no electricity on the crossing gate in case we use solar energy. 

Uses :- 1) This project will be self control safty from the vehicle an accident on the 

railway crossing gate. 2) This project will be used for saving man power and money of 

railway deportment. 3) On diesel train road we used solar energy and saving the 

elecrycity. Apparatus :- Playing Train, Electric motor, Aluminiam slate, Trasfarmer,

MATHS PLAYGROUND 

Every day, in every school throughout the country at a specified time of the day, a 

teacher enters the class room. Children are perhaps hesitantly. Perhaps grudgingly take 

their books and 'do Mathematics'. For them, the subject is an asset of dry rules and 

procedures leading to some 'answer'. Which is not of much significance anyway? They 

do not develop a love for the subject because they do not know the value and use of it. 

So whenever a new topic is to be introduced it is better to draw examples from real life. 

Well! Numbers can entertain us; they can puzzle our Companions and can raise us to 

the level of a magician! Here is some model- The model is on! Let us be spellbound 

with Numbers.

BIOSPHERE MONITOR 

Aim: To effectively bring down the rate of global warming. 

Method Adopted: Capturing and liquifying atmospheric CO2 and rendering it 

harmless. 

Liquification Procedure: The CO2 rich air is sucked from the atmosphere and 

bubbled through a tank of liquid CO2 kept at 880 F and 5.1 atmospheric pressure. The 

gaseous CO2 in the air becomes liquid during the passage through the tank. 

The other gases in the air are allowed to escape into the atmosphere. 

Disposal of Liquid CO2 : 1. Liquid CO2 is in high demand as it has many industrial 

uses. 

2. Liquid CO2 can also be stored under used oil fields where it mobilises and pushes up 

the unmobilised oil from below. 

3. Liquid CO2 can also be stored under basalt rocks where by reaction, it becomes 

harmless calcium carbonate rocks. 

4. Liquid CO2 can be stored under sea beds. Even if it managers to escape from under 

the sea bed, it reacts with sea water and forms harmless clathrate hydrate sediments on 

the sea bed. 

Conclusion: CO2 is one of the chief culprits 

of global warming. This method effectively 

brings down the atmospheric CO2 content 

and thereby the global warming.

SYSTEM OF RICE INTENSIFICATION 

The SRI methodology was developed in 1983 by Fr. Hendry de laulanic in 

Madagascar. Single seedling with wider spacing and good soil aeration are the main 

principles. Now SRI has spread in more than 56 Countries. SRI has some advantages 

such as higher production, water saving, less input(seeds), no external dependency for 

agro chemical like fertilizers & pesticides ,less lodging, conservation and 

sustainability of ecosystem, etc. 

1. Nursery: (1) Approximately one cent nursery of raised Beds to transplant one 

acre of paddy (2) Seed rate per acre: 3kg of any variety of Paddy. 

2. Plant single seedling/hill: (1) Transplant single & young seedling 8-12 days old. 

(2) Remove seedlings carefully without Damaging the roots and seed sack. 

3. Wider spacing: (1) Transplant seedlings with a spacing of 25*25cm ( squares 

using space marker or rope. 

4. Weeding & soil aeration: (1) Use mechanical weeder [cono-weeder] for weed 

management: uprooting in situ ploughing of seeds. (2) Drudgery reduction for the 

women. (3) Evenly formed, healthy, multiple tillers. 

5. Water management: (1) Alternative “wetting & drying”. (2) Keep the soil 

moist but not flooded. (3) 1-2cm water is maintained in the field as soon as the panicle 

initiation starts. 

6. More of organic manure: (1)No chemical pollution. (2) Healthy & quality food.

GLOBAL WARMING AND CARBON DIOXIDE 

Global warming is the most burning issue of the century. It has caused major ecological impact on all 

living creatures (Human, animals and plants). CO 2 is a major Green House Gas. So as we increase 

the quantity of CO2 in our atmosphere the temperature of Our Earth will increase drastically as hear 

rays will not be able to escape from the atmosphere. 

So we need to take steps for 

·Reducing the quantity of CO2 being released in the atmosphere. 

·Planting more and more trees. 

·Using eco-friendly fules. 

·Using non-conventional sources of energy.

TESLA COIL 

Tesla coil is a device that produces millions of volt from its output. This coil employs the loss 

coupling RF induction to produce a high frequency output voltage with Imax of about 2 to 4 ma. This 

Pulsed output can be employed to produce some novel electromagnet effects only visible at very high 

power, voltage and frequency. Current Tesla coil consists of a transformer that converts 1300 watt ac 

to 15000 v 80 ma. This output is then directed to a handmade glass capacitor which employs 12 glass 

plates Aluminum foil. Then in parallel of is a spark gap which when capacitor gets charged pulses an 

arc which completes the circuit and the current is then passed to a 10 turn primary coil in whose 

resonance is a hand-woven 1200 turns secondary coil. And the arc discharges the whole circuit 

becomes an LCR oscillator creating an extremely fast changing magnetic flux in secondary 

producing millions of volt from output. These coils can be used in Future water powered cars, 

ionocraft, high energy pulsar, plasma gun. Presently it is used in x-ray devices, violet-ray devices etc.

TO STOP ….. ! THE TRAIN ACCIDENT 

As Compared to the Other Popular means of transportation in the world Train Transport is the 

most easily accessible transport. Due to High Velocity of the Trains coming from Opposite 

directions on the same track, they can't be halted suddenly by applying brakes If in the engine, the 

mild road of iron is wrapped by copper wires which are polished by bad conductor solution and 

current is passed through the wires, magnetic field is produced. On the both ends of coils, 

opposite pole are produced. 

By producing same poles in all the trains, diffraction can be created. The Drivers of the trains 

coming from opposite directions can produced the same magnetic poles by switching on the 

current. To support the above system evenby Producing the magnetic field in the wheels of trains, 

the track can be attracted. 

It's result will in reduction of the velocity of the trains and help the Drivers in applying the breaks 

and stop the trains. It will provides us safe & Secure journey and check the human loss.

TOILET MODIFICATION IN INDIAN TRAINS 

This Project is an attempt to solve the following problem arising due to the present mode of 

disposal of human waste in Indian trains with additional benefit of recycled the water after the proper 

treatment. In the present model the water used in the toilet is filtered and chemically treated and 

recirculated. So that water usage can be minimized as well as the release of the untreated water on to 

the tracks can be avoided. After separating water , the human excreta is stored separately & can be 

used to produce biogas. There are four scientific principles used in this project. 

These are: 1.Collection 2.Filtration 3.Disinfection 4.Recirculation of water 

The main application of the model is to minimize the pollution. Human waste, especially of sick. 

Passenger may contain a large number of germs of many disease like diarrhea, cholera, typhoid, 

hepatitis and other water born disease beside parasite infection. Parasite like hookworm, roundworm 

and pinworm are spread mainly through human waste that result in the spread of communicable the 

environment & promotes unsanitary condition. In addition of the urine also cause fastening which 

can pause huge accident. Thus because of a human waste lots of people may lose their life. This 

model ensures the safe disposal of human waste and beside this. It also helps in water scarcity in 

trains. The human waste also can be used in bio gas plant for energy production.

SAVE WATER, SAVE ENERGY 

Introduction :- In our house after the filling up of the tank, switch of the water pump 

is usually shut down. If the above - stated system is not followed or making delay to 

switch off the pump due to forgetting, it leads to sheer wastage of water and electricity. 

In accordance with the proposed model, the pump will be automatically stopped after 

its being filled up. 

How does the Model Function :- The proposed model effectively works on the 

systematic projection of a bell push switch and a three pin socket. A pump is attached in 

that socket .Electricity will be supplied to this board. If the bell push switch is on, the 

pump will be started. The pump will run and will stop Just after the tank being filled up. 

A wire with graphite or carbon at its end is sank in the 

tank. Acting on the way the current (0.7 – 1.2 volt), will 

start moving through the water to the transistor of the 

Electronic board when the water level will rise upward 

.Instantly the transistor will activate a relay leading to 

the stoppage of electricity in the pump and transformer 

permanently. 

Conclusion :- If the proposed model is used 

extensively, it will certainly save a huge amount of 

water as well as electricity.

SIGNAL FOR OVERLOADING 

Road accident is a daily event in motor vehicles of them. The over loading of vehicles 

can not be seen from out side. I have made a model how to determine the over loading 

of vehicles from outside. I have used three different colors light like green, yellow and 

red to indicate it. When the bus is loaded its ability, the green light will be lighted 

automatically. If the loading of the bus is a little of its carrying weight i.e., the carrying 

ability of the bus, the yellow light will be lighted. When the loading of the bus is more 

weight then its ability, the red light will be lighted. It indicates that accident may occur 

at any stage.

REPRESENT THE AREA OF A CIRCLE 

BY THE AREA OF A RECTANGLE. 

Purpose- To get a clear idea about the application of Geometry & the relation 

between Algebra & Geometry. Also it gives the idea about circle, rectangle & square. 

Required Instrument – Thin wood (Pitch Board),Cutting instruments ,various color 

marker pen etc. 

Implication of the project – To fulfill the mission of SSA educating every child of 

the nation, we feel a crying need of the teaching – learning process attractive .More 

ensuring regular attendance of the pupil does not suffice to make them taught 

successfully. The traditional way of teaching creates little interest among the tender 

learners especially in the harder subjects like mathematics. On the other hand every 

human being is bestowed with some inherent merits of invention & creation. A child 

thrills with joy when he can do something in his own effort. 

The projects which we are going to represents are innovated on some basic theorem of 

mathematics. Our motto is to allow our learners “learn and enjoy” applying the play 

way method in the teaching – learning process. The 

first effort is to convince how a basic algebraic 

process can be experimented through a geometrical 

approach and the second has attempted to find out an 

area of a circle converting the same in to a rectangle. 

Both of them claim novelty and we are sure thy are 

able not only to remove the monotony due to 

traditional teaching – learning system in the subject 

but also to instigate their innate qualities of invention 

and creativity which is or ultimate goal.

USE FULL APPLICATION OF NON-BIODEGRADABLE 

ENERGY (BIO-GAS) AUTOMATED SIGNALLING SYSTEM 

Introduction :- As the biodegradable energy decreases in modern civilization, Govt 

along with human civilization has given an emphasis in the use of non-biodegradable 

energy. These are the emblem of non-pollutant .Use of non-biodegradable energies 

such as bio-gas, cow-dung in our everyday life, forecast a new pollution free 

civilization. Full-fledged use of such energies signalling the modern civilization. Light 

and thermal energy can be produced by cow-dung and automation depends on this 

energy. 

Equipments :- i.Adequate cow-dung jars. ii.A little water(75ml). 

iii.Six airtight jars. 

iv. Electrode – Copper plate, Zink plate, Copper wire, electric bulb. 

v. A model of a bridge. 

On the basis of these equipments, we can show that a bridge can't suit beyond its 

overweight. Whether an over weighted vehicle may 

pass or not through a bridge, depends on a signalling 

system that can run by non-biodegradable energy. 

This system is placed both before and after a bridge 

and it works when an over loaded vehicles pass 

through it. This system can identify the vehicles 

.Suitable or not for the specific bridges. 

Advantages :- i. This system keeps safe the total 

transport system. 

i i. This system saves our economy.

MANUAL ELECTRICITY PRODUCING DEVICE 

(ELECTRICITY FROM STATIC CYCLE GYM. AND DRUM GYM) 

Introduction : In the present age of technology we know how great is the demand of 

electricity. We also know the utility of taking exercise to keep us fit. This newly 

invented device will serve both the purposes at a time. In the Gym, the physical labour 

that we discharge to enjoy good health, will be converted into electrical energy by dint 

of the Static Cycle Gym/ Drum Gym. 

Static Cycle Gym : At the time of Static Cycling, the dynamo attached to the rim with 

a belt, will produce electrical energy at the cost of mechanical energy and the produced 

energy will be sufficient for a small family (consisting of 4/5 healthy members), if they 

individually take exercise half an hour a day. Besides, the produced energy may be 

stored in a storage cell (12 or 24 volt) for further use. 

Drum Gym. : In this field also, when one walks or runs on the drum, it moves along 

with a co-axial rim and the dynamo fixed with a belt to it, produces electricity just as 

the previous one. To get more energy the R.P.M. is to be increased by fixing a gear box 

to it. 

The characteristics and the implications of the newly 

invented modules :- i. It will produce electricity 

without polluting the nature. ii.It will develop the habit 

of taking exercise among the people regularly resulting 

in keeping them physically fit, mentally alert and 

socially sound. iii.No bill is to be paid for electricity. 

iv.It will form in us the habit of proper use of electricity. 

v.It will inspire people to take exercise and evoke the 

innovative mentality.The production cost of the device 

will not exceed the capacity of a middle class family.

SOLAR STORM 2012 

INTRODUCTION : We get sunlight by the reaction of Hydrogen, Helium, Radon 

etc. gases in the Sun which generate both heat and light in the Sun. 

But when this reaction occurs in a huge proportion then extra energy gets out and that 

spreads out like storm that's called Soar storm. 

According to research scientist predicts that this Solar Storm will may happen in 2012. 

Effect : The result of this storm are furnished below :- 

1.The Magnetic Field of the earth will weaken. 

2.Tsunami earthquakes can occur in various areas. 

3.Ionosphere can be ionized. As the effect telecommunications and 

Radio broadcasting system can be disturbed. 

4.A large amount of radio activity can spread. As the result of which all the power 

plants can be destroyed at a time. 

But it is unfortunate that our science in spite of its brilliance unable to get 

a solution of it.

MAGNETIC LEVITATION AS SOURCE OF VERSATILE 

POWER SUPPLY (VPS) 

PREPARATION OF THE POWER SUPPLY: 

When electricity passes through a conductor, a magnetic field is generated around the 

conductor. When the magnetic field changes, a temporary e.m.f. is induced in the coil. 

This phenomenon is termed as magnetic induction. Uniting these two concept, a 

magnetic levitation set (MLS) has been prepared by using a primary coil, some 

secondary coils and an iron core. The magnetic levitation set is considered as the step 

down transformer required for constructing a battery eliminator. If the ends of the scoil 

are closed, it jumps. The voltage across the s-coil varies, if it is moved along the 

length of the core. So, the variable power supply is prepared. Now this variable A.C. 

can be simply transferred to variable D.C. by using a bridge rectifier circuit. 

USES OF THE VPS: Apart from the jumping of aluminium ring experiment, 

phenomenon of electromagnetic induction, attraction between like currents and 

repulsion between unlike currents, development 

of high temperature due to eddy current, 

experiments on LR circuit for determining selfinductance 

L, phasor diagrams, determination of 

mutual inductance, peak voltage and rms voltage 

of an A.C. source, the ohm's law and its different 

facts … etc. can be demonstrated with MLS.

ECO-FRIENDLY POTATO BATTERIES 

MAY POWER THE FUTURE 

Fossil fuels (coal, petroleum, natural gas, and their derivatives) provide more than 

85% of the energy used by mankind today. Unfortunately, the reserves of those fuels 

are not infinite. Scientists predict that within the next two centuries we will run out of 

those valuable energy sources. This is you experience energy crisis. Clearly, 

something must be done. But what? 

This question forced me to find out some sources of alternative energy and finally I 

find out a good source of alternative energy. It is potato (a vegetable) which could be 

the Batteries of the Future. 

How the Potato battery works: 

A potato battery is an electrochemical battery. An electrochemical cell is a cell in 

which chemical energy is converted to electric energy by a spontaneous electron 

transfer. Potato contains substances such as ascorbic acid, citric acid, phosphoric acid 

and NADH. In the case of the potato battery, the zinc in the zinc electrode reacts with 

the copper electrode. The potato acts as a 

sort of buffer between the zinc ions and the 

copper ions. The potato conducts 

electricity, yet keeps the zinc ions and 

copper ions separate, so that the electrons 

in the copper electrode are forced to move 

(generate current). It's not enough power to 

shock us, but the potato can run a small 

digital clock or a calculator.

PRODUCTION OF ELECTRICITICY FROM 

EXHAUSTED BATTERY 

This type of battery, which is actually zinc-carbon dry cell, is considered as a primary 

cell because the cell is not intended to be recharged. But we have employed a technique 

to produce electricity from an exhausted battery, just by using a solution of ordinary 

salt, sodium chloride (NaCl). NaCl is ionised in water and produce positively charged 

sodium ion (Na+) and negatively charged chloride ion (Cl-). Then, sodium ion moves 

towards negative zinc cage and reduce deposited ZnCl2 to metallic zinc. 

Simultaneously, Cl- reacts with ammonia stored on carbon rod to form ammonium 

chloride and there by pure carbon rod becomes free. Thus, sodium ion and chloride ion 

recharge metallic zinc and carbon rod, 

We have designed a circuit to examine the working ability of the recharged battery. The 

picture of our model indicates the circuit. A fan and few lights are connected with 

cathode of nine inter-connected batteries by an electrical wire. Now if another wire 

from the fan and lights is brought in contact 

with the wire connecting with the anode 

using a switch, fan rotates and lights glow. 

This proves that the exhausted battery have 

become active by NaCl solution. This 

technique may be utilised for the power 

generation in future.

HYDRAULIC BRAKE TO DEMONSTRATE BLAISE PASCAL'S 

LAW AND ITS COMPARISON WITH AIR BRAKE 

The most important safety feature of an automobile is its Brake System. A brake is a 

mechanical device which inhibits motion. Brakes, one of the key parts of any vehicle, 

without which it is virtually not possible to use the vehicle for travel, should not be too 

weak as it provides safe, repeatable stopping which is the key to safe motoring. 

Therefore, a clear understanding of the brake system is essential for anyone involved 

in servicing vehicles. 

There are basically three types of brakes used in automobiles: 

·Mechanical brakes ·Hydraulic brakes ·Air brakes and related type of brakes 

The main braking system of the car works by hydraulics as it can transfer a huge 

amount of energy. This means the driver presses brake pedal, liquid pressure forces 

pistons to apply brakes on each wheel. Based on Blaise Pascal's Law which states that 

pressure applied anywhere to an enclosed body of fluid is transmitted equally to every 

other part of liquid, the hydraulic brake system uses brake fluid to transfer pressure 

from the brake pedal to the pads or shoe. By exercising the pedal, brake fluid transfers 

this pressure to the brake pads. This transfer of 

pressure is reliable and consistent because 

liquids are not compressible, In brief, when a 

driver applies pressure at the brake pedal, the 

mechanical force i.e. stepping of driver on pedal 

is changed to hydraulic pressure which is 

transmitted through liquid to respective wheel 

cylinder and changed back to mechanical force.

BALANCE FOR THE BLIND 

Introduction : Visual impairment is one of those disabilities which may cripple a 

person for life. This simple new model will be of great help to those who are visually 

impaired. They can measure the weights of different articles without any help from 

others. 

Description : It is a modified version of an ordinary balance. In this balance a semicircular 

plastic tube is attached to its main frame with the help of tapes. Some mercury 

is poured into the tube. Two electric wires are inserted into the two open ends of the 

tube. The ends of the wires are kept in such a way that they touch the surface of the 

mercury when the balance is in equilibrium position. Since mercury is a good 

conductor of electricity, the moment, the ends of the wires touch the surface of the 

mercury, the circuit will be completed. Two dry cells and an electric bell are also 

connected to the circuit. The position of one beam will tilt to one side when weights are 

kept on it and when the balance is in equilibrium state the circuit will be completed, and 

the bell will ring instantly. Thus the exact weights of different articles can be measured.

INVISIBLE LIGHT 

The exhibit consists of a picture of 'Solar System' which is an ordinary object in 

ordinary light. When it is seen in U.V. light it emits light with glows. The idea behind 

showing our 'Solar System' with bright planets against a dark-ground stem on using 

'Fluorescence'. 

'Fluorescence' is the property of certain compound i.e. Barium Palatino cyanide, 

Barium Chloride etc. absorb invisible high energy beam and transform into visible 

light emerging from it. 

For the project thus (i) a fluorescence compound and (ii) a high energy source are used. 

Here Ba[Pl(CN)6] is used in painting the target parts. For the source , x-ray, , - source 

could be used. Here, U.V bulb of low Walt is used. 

The parts of picture absorb high energy frequency i.e. the frequency of light which 

wavelength (4 x 10-7 nm – 6 x 10-10 nm) are invisible region (wavelength: 4000A0 – 

7000A0). 

So the planets are visible in the absence of light. All the high 

energy source are biologically hazardous to handle. U.V source 

is much less hazardous and used with precautions.

MASS COUNTING MACHINE 

Mechanism : (use of light and darkness) The L.D.R is placed in a black wooden box 

a very narrow hole. Now, if we use the torch and drop Light on L.D.R. through the hole, 

the resistance of L.D.R. decreses and the 'n' and 'y' parts of the button are connected and 

the calculator calculates and gives the cardinal numbers serially after using the torch 

again and again. 

Use for Mass counting : 

If we place the L.D.R. at one ride of the entrance of a hall and put the torch on the other 

side, then when people enter into the hall one by one, the Light – Falling on L.D.R. is 

disrupted again and again. And this is how, the calculator automatically displays the 

number adding 1 every time at last, we get the total count after deduction of 1 from the 

totl as the calculator already displays '1' after using 1 button at first. 

·Limitation : Only one man should be entered into the hall at one time. 

·Advantage : This model is very tight and it atakes a small place to put and it is not an 

expensive one to build up.

ECONOMICAL COLD STORAGE 

The preparation starts with making a plywood box having a door with lock . The floor 

of the box contains many small holes. The roof of the box contains a big circular 

hole. The inner walls and door of the box are to be covered with thermocol which is 

non-conductor of heat. Long jute fibres are thrust into the small holes of the floor from 

outside the box. The box is to be placed on the metal tray full of cold water. Long jute 

fibres will remain dipped in water. Through the hole of the roof a long cylinder, 

which should also be a non-conductor of heat , is entered and it is fixed with the 

roof. The joining of the roof and cylinder should be air tight. Now the burning point 

of the kerosine lamp is entered through the 

middle portion of the cylinder and make it air tight. Now the project is ready to work. 

At first the kerosine lamp is se t on fire . Due to burning of the lamp the air inside 

the cylinder becomes hot and lighter and comes out of the cylinder through the open 

mouth. As a result, there creates a vacuum in the lower portion of the cylinder. To fill 

this vacuum relatively cold air full of moisture will come through the wet jute fibres 

.Due to the evaporation from the upper surface of the water kept 

in the tray, the latent heat of evaporation is taken out from the 

rest of the water in the tray and as a result the air inside the box 

becomes a little bit cool than it was before. This process will 

continue and temperature of the inner side of the box will fall 

gradually. For efficient functioning of the project , the box 

should be so prepared that there is no other way to enter air 

inside the box except through Jute fibres kept in the lower 

portion of the box.

NON-CONVENTIONAL SOLAR ENERGY 

We are in the age of scarcity of conventional energy Source . Comprehensive and 

pollution free use of non-conventional energy can save us from this crisis. In this 

backdrop the use of Solar Energy is the best policy. 

Annually we get 250 – 300 sunny days in India which offers 5000 Trillion KWh 

energy most of which got unused. As of now we use SPVC for exploitation of Solar 

Energy but it is much expensive. Ours is an ideal model to harness solar rays. 

Here we use Sun rays to create convection of air from which we get electricity through 

turbine or can store potential energy in spring by winding it through turbine. We can lift 

water into roof tank by this Solar-borne electricity and therefrom we may have 

electricity at night by falling water into a turbine. We have used Electronic-Waste to 

get electricity directly from Sun rays. By concentrating Solar rays compressed vapour 

is created by which we may cook food or generate electricity. ' National Solar Mission' 

vows to get 1000 MW electricity from Solar Energy by 2013. The most lofty 'Thor 

Desert Project' aims to extract Solar Energy from 35000 Sq.km. of area .'Ministry of 

Renewable Resource ' is eager to make all mobile towers in 

India to go solar. 

To materialize the Schemes galore we hope our model must 

be a suitable one.

school building has been calculated from the annual average rain fall of Kalna 

subdivision. 

·Total annual requirement of drinking water for the students has also been calculated. 

·For the storage of rainwater storage tank is installed. 

·From the storage tank rainwater is piped to Filter unit and finally to the drinking water 

tank. 

·Tank capacity designed for the dry period – Area of roof of school – 500 Sq. Mt. 

Volume of rainfall (in liters) on the roof. - 500 Sq Mt. x 1.7 Cu.Mt ( I,e height of 

average annual rainfall of kalna sub-division) 

·8,50,000 liters Volume of effectively harvested rainwater (Assuming 60% of the total 

rainfall is effectively harvested) - 5, 10,000 liters. 

Assuming approx requirement of water per student during school time is average 

1 liter per day. So daily requirement of driking water in the school is 700 liter. 

Average school days in the school per year are 200 days and 

within 200 days average dry days are 120. 

Total requirement of drinking water during dry days.

ACCIDENT PREVENTER OF UNGAURED 

RAILWAY LEVEL CROSSING. 

Now a days it is a recurring problem of Indian Railway to prevent accident on the 

way of unmanned level crossing. 

An easy method has been applied in this Model to make alert the passers by or any 

driver of vehicle when they will cross over the unmanned Level crossing. 

A mini electrical generator has been established to generate electrical power by the 

mechanical movement of rail when the train will run over the rail line, because of low 

amplitude of linear movement of the line will convert a rotary motion of a large gear. A 

small gear is coupled through a chain with the large gear for developing rotary speed. A 

rotary magnetic field which is formed by two poles of North and South directly 

coupled with the shaft of small gear. Two induction coils are existing at 1800 angle 

within the magnetic field. 

When the rotary magnetic field will gain a rotary motion within the Induction coils, 

then an induced voltage will be developed 

at the end of the connected circuit of those 

coils according to the law of Flemings 

Right hand rule. 

A Richfield made with four diodes to 

convert D.C. from A.C. for constant I 

lowing a L.E.D. 

A Buzzer can also be established here to 

make alarm.
