ABSTRACT:
A steam engine has a pipe shaped fluid container, a heating and cooling devices respectively provided at a heating and cooling portions of the fluid container, and an output device connected to the fluid container, so that the output device is operated by the fluid pressure change in the fluid container, to generate an electric power. In such a steam engine, an inner radius “r1” of the cooling portion is made to almost equal to a depth “δ1” of the thermal penetration, which is calculated by the following formula (1);δ1=2⁢a1ω(1)wherein, “a1” is a heat diffusivity of the working fluid at its low pressure, and “ω” is an angular frequency of the movement of the working fluid.
