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.
