It has put forward a concept of generating electricity from alternate sources on a natural temperature difference in this paper. There is an introduction of the utilization of energy as well as its developing tendency. It elaborates the principle of generating electricity with the analysis of the alternate sources and the working substance. On the supposed condition, it has made a thermodynamic analysis of the circulation. It has also calculated the thermal efficiency of the system on given parameters. Finally we can obtain the influencing factors of the thermal efficiency, which is valuable for the optimized design of the system.
