PROBLEM TO BE SOLVED: To provide a power generator utilizing a moderate heat temperature difference of several tens of degrees. SOLUTION: A plurality of pressure tanks are arranged for heating water with a heat source and a hot water feed pipe is disposed between adjacent tanks for circulating the hot water to relay the pressure tanks. In each pressure tank, an extrusion pressure needed for the circulation is obtained from a pressure accompanied by vaporization of a low boiling point medium. A liquid feed pipe is connected to the lower end of the pressure tank to inject the liquid of the low boiling point medium into the hot water. A gas feed pipe is connected to the upper end of the pressure tank to recover the gas of the low boiling point medium. A power generator for rotating a turbine by utilizing the pressure of feeding hot water is connected to the hot water feed pipe. A condenser is provided for the low boiling point medium so that the gas recovered by the gas feed pipe is liquefied by cooling to feed to the liquid feed pipe. COPYRIGHT: (C)2004,JPO
