Proceedings <strong>of</strong> the National Conference on<br />

Trends and Advances in Mechanical Engineering,<br />

something that can be heard by the human ears. But the vibrations that have been generated once, whether heard<br />

or not, produce an immediate effect on the environment. The subtle vibrations apart from the vibrations <strong>of</strong> the<br />

mass particle also have an effect. Slight meditation makes this clear. The enormous electromagnetic vibrations<br />

being generated for mass tele-communication are also having a detrimental effect. It is well known that the<br />

radiations from a mobile phone or the computer screen are harmful. Similarly the artificial electromagnetic<br />

waves travelling all around in the atmosphere are having a negative effect on the various natural protective and<br />

nourishing phenomenons taking place in the environment and the outer layers <strong>of</strong> the atmosphere.<br />

The above four reasons together are certainly responsible for the deteriorating environment on the earth. Time is<br />

running out and immediate action is needed. If there is catastrophe in the near future in the form <strong>of</strong> solar<br />

storms or earthquakes, it will not be because <strong>of</strong> the Mayan Calendar ending. It will be modern technology<br />

made.<br />

2. Computer Aided Design; Computer aided Manufacturing<br />

The computer aided automatised and fast machines are bringing out better and complicated designs and<br />

beating the traditional lathes in production. Jobs for computer and s<strong>of</strong>tware engineers have been generated.<br />

Money for the owners has been generated. But all this mass production has thrown out millions <strong>of</strong> people out <strong>of</strong><br />

job the world over. Slums in the overwhelming cities have come up. People have been uprooted from their<br />

villages and with that from their natural and social environment. Let us take some examples. There were<br />

thousands <strong>of</strong> weavers all over India. They were earning good livelihood before the advent <strong>of</strong> European<br />

machines. There were thousands <strong>of</strong> copper and brass utensil makers in towns. Similarly there were the<br />

shoemakers, blacksmiths etc. They have been almost all thrown out <strong>of</strong> jobs. The tractors used for ploughing the<br />

land have not only spoiled the land but have made the oxen, the farmers jobless. There is another angle to it and<br />

cause <strong>of</strong> the suicides by the farmers. A wealthy farmer, instead <strong>of</strong> working for eight hours on land finishes his<br />

task within say two hours. The remaining time is used in gossip, drinking or other non productive activities. This<br />

leads to mental and social problems. So it is a misunderstanding that industrialisation generates economy and<br />

employment. It is for the few and not for the masses. This is the cause <strong>of</strong> disparity and hence communism and<br />

capitalism have come into existence.<br />

3. Plastics and nano-technology<br />

Plastics have a long life as compared to wood. They do not rust as compared to iron. So, new and better<br />

plastics in various forms are coming to existence. More efficient moulding machines are taking birth. The<br />

problem in plastics is threefold. First the long continuous polymer chains do not have sufficient pores. So air<br />

etc cannot pass with ease. Thus these long artificially created molecules when go along with water or food clog<br />

the pores inside the human body or animal bodies. This is hazardous to health. This concept <strong>of</strong> non clogging <strong>of</strong><br />

arteries, veins and numerous other passages, meant for flow <strong>of</strong> liquids or air or electromagnetic fields (the<br />

“Prana”), is laid out in Ayurveda (“Vilekhanam”). One need not eat plastic for this. The bear contact <strong>of</strong> the water<br />

and food items with the containers entraps very minute particles <strong>of</strong> plastics not visible to normal eyes. Secondly,<br />

plastics are burnt by common man for heat or disposal. The same long polymers are now disposed <strong>of</strong> into the<br />

atmosphere and clog the respiratory systems. Apart from the long chained molecules, some “Amedhya”<br />

substances are also released. That is clear from the smell from the products <strong>of</strong> combustion. Thus pollution is<br />

many fold. The third problem is recycling. It is well established that plastic bottles, polythenes bags etc. take lot<br />

<strong>of</strong> time in getting back to the nature. Rivers and land seems to be strewn all over with plastics and polythene<br />

bags. Visit the villages, visit the cities and visit the rivers. You may not find them in England or America but<br />

visit their land fills.<br />

Similarly nano-technology products, because <strong>of</strong> non porosity, can be much more harmful to health and<br />

environment. For example, there is a saying that nano socks or pants will never get dirty. But look the poor<br />

man’s feet or legs will certainly be uncomfortable and deteriorate because <strong>of</strong> no contact with air. Porous<br />

comfortable cotton clothes are needed.<br />

4. The mission to mars and outer space and air travel<br />

Man is curious to land on Mars or explore the outer space. Rocket propulsion is a must to take the pay load out<br />

<strong>of</strong> the earth’s pull. Thousands <strong>of</strong> increasing number <strong>of</strong> planes are flying every day around 12 km high on our<br />

heads. Modern research is to come up with novel techniques that reduce drag and generate extra lift. Still<br />

millions <strong>of</strong> tons <strong>of</strong> aviation fuel is being consumed to produce high velocity jets to overcome drag and generate<br />

lift. The problems associated remain the same as discussed before: excessive oxygen consumption; heat and<br />

noise release to the atmosphere.<br />
