Maintenance & Repair

In view of the fast depletion of our non-renewable energy sources like coal and petroleum, and because o pollution resulting from burning of coal and other fossil fuels, there has been a move to find substitute to fossil fuel for obtaining energy. Since the energy of the atom had already been unleashed in the form of a Bomb, efforts were made to release atomic energy in a controlled manner. The device used for this purpose is called atomic reactor. Nuclear reactors produce heat, which is used to generate steam, for rotating turbines for generating electricity. It is estimated that 1 kg f natural uranium. Written as 235 U, generates energy equal t that produced by 35000 kg of coal. Energy production from nuclear fuel like uranium is relatively clean, efficient, and can serve as substitute for coal and petroleum. However, nuclear reactors need to be situated at places fa away from human habitation. They have to be operated under strict safety control, to prevent any accidental leakages of radioactive material. The radioactive wastes have to be carefully disposed off. India is very short of energy and all of you may have heard or experienced power cuts or load=shading We have plan to set up more nuclear power plants and meet our growing need of electric power

Wave and Tidal Energy

Waves and tides are another sources of energy which is perpetual and can be harnessed for generating electricity, particularly where sea water can move into a narrow cut, such as is provided naturally where rivers flow into the sea. Energy carried by water has also been widely used in India’s hilly regions, since a wheel with pedals can be made to turn when it is put in a fast flowing stream. Flour mills of small size built on this principle were used in Kashmir for long time. In fact, large "hydroelectric" power stations work on the same principle. A natural of artificial water fall is made to turn a modern kind of pedal wheel, called a turbine, which upon rotation generate electricity.
