ABSTRACT:
A hydraulic engine for the conversion of thermal energy as from the sun into reciprocating mechanical energy, the engine comprising a long cylindrical pipe filled with water and having a thermal receiver at one end and a bellows at the other end. Boiling of the water at the receiving end of the pipe by the thermal energy sets up pressure and displacement wave-fronts which travel down the length of the pipe to expand the bellows and to actuate the connected mechanical load.
