PRODUCTION OF ELECTRICITY BY EXPANSION AND CONTRACTION IN VOLUME OF SOLVENT BY USING SOLAR ENERGY

摘要

Sunlight is abundant source of energy. Solar energy is used for heating water. Controlled flow of this hot water along with normal water would regulate temperature of solvent contained in closed chambers. Expansion and contraction in the volume of solvent can be achieved by varying its temperature in controlled way. This controlled increase and decrease in volume of solvent is used for mechanical rotation of crank shaft which is further connected with gear box and generator. This set up is used for production of electricity. Solar energy is available in many countries round the year. Hot water can be stored in insulated water tanks and hence this process can be continued for production of electricity on 24 hour basis. This process is free from pollution and cheaper as compared to other methods of electricity production. No input material is required once production process is started.
