This project is aimed at producing electricity by using the vast heat content of atmosphere. The scheme is basically aimed as producing electricity by extracting heat from atmosphere. In this project, this is done by using mechanical arrangement similar to heat pump. This system is used to squeeze energy from huge volumes of air and to produce temperature difference by which energy can be produced. It is to be noted that fresh water and salt are added bonus to this project, as salty brackish water can be used in this project. This is done by vaporizing water inside an enclosed container named “Evaporator” with the help of a vacuum pump. As the vacuum pump sucks air from the container, the water inside began to evaporate and in this process collects its latent heat of vaporization from water. For that reason, the water inside becomes colder and heat began to flow in from outside. Thus in effect, the latent heat of vaporization of water is collected from outside atmosphere. In the open-cycle OTEC, vapor is produced in the same manner and on experiment it was found that to have vapor flow rate of 1 kg/sec, power needed at the vacuum pump is 3 KW. Whereas, the latent heat embedded in 1 kg of vapor is 2.31 MW. After the vapor is produced, it is heated further with adiabatically compressed, hot air. After heating the vapor in the Boiler, the hot, compressed air is passed through the Evaporator to give up its residue heat to the water inside. The process is the same as that of common heat pumps sold in the market. And finally, the temp. diff. between the Boiler and the Condenser is created by suddenly releasing the compressed air at the Condenser. And thus a system of real efficiency of >50% is created.
