ABSTRACT:
A heat engine using as the working medium a non-compressible substance such as a liquid or a solid. The non-compressible substance in an enclosure is moved alternately relative to and between a high temperature zone and a low temperature zone to undergo expansion and contraction, which are transmitted directly or indirectly as mechanical displacement by an output piston. As the non-compressible substance, polyethylene or paraffin is most desirable.
