PROBLEM TO BE SOLVED: To provide a stable power generating device having no adverse effects of initial investment, maintenance management costs and air pollution, and being not affected by weather.SOLUTION: A power generating device includes an evaporator, a differential pressure rotary machine, a condenser, a liquid receiver, and a power generator. When an appropriate amount of a coolant gas is sealed in the device and hot water having a temperature of about 50°C is fed into the evaporator, a gas having high pressure is obtained. At the same time, when cool water having a temperature of about 20°C is fed into the evaporator, a liquid having low pressure is obtained. The pressure difference is applied to vertically move a piston to rotate a crankshaft which is coupled with the power generator. |
