内容記述 | Japan produces less natural resoures, so it is the most important problem for Japan to develop a perennial natural energy. One of them, an electrical power generated by temperature difference of a ocean wather (EPTD) has been exploited for practical use. The EPTD is generated by expansion of liquefied ammonia, but electrical power produced by wather vapor (EPWV) is generated by thermal expansion of water vapor. Therefore, the EPTD system has an extra equipment for liquefaction of ammonia, comparing with the EPWV system, because an ammonia of b. p. -33.5℃ can not be liquefied by only cooling the ammonia gas which is vaporized from the liquid ammonia, using the bottom water (~4.5℃) of deep ocean. The thermodynamics says that the thermal engine can not obtain 100% efficiency with every efforts, because of the energy loss which is inevitable to the thermal engine. The thermodynamic calculation of the thermal energy which is necessary for obtaining some electrical energy shows that the ratio of the energy for the EPWV system to the energy of the EPTD is 1:17. It means that the EPTD system wastes more fossil fuels than the obtained perennial natural energy. | |||||
