Abstract: A mechanical engine driven water pump is disclosed for converting energy from an input heat source to a reciprocating mechanical output for powering the water pump. The mechanical reciprocating engine comprises an engine bore having an input port and an output port. An engine piston is disposed in the engine bore. An engine valve assembly is slidably mounted to the engine piston for communicating the input port and the output port with opposed sides of the engine piston for effecting reciprocal motion of the engine piston. A piston shaft is connected to the reciprocal motion of the engine piston to provide the reciprocating mechanical output the water pump. A stuffing box is interposed between the mechanical reciprocating engine and the reciprocating mechanical output for providing a positive seal for the mechanical reciprocating engine. The heat source may comprise a solar heat source, a geothermal heat source, a byproduct heat source or the external burning of a petroleum product.

Abstract: A universal heat engine is disclosed for converting energy from an input heat source to an output. The universal heat engine comprises a heat engine section and an output section. The heat engine section includes a heat engine bore receiving a heat engine piston. A heat engine valve assembly communicates with the heat engine bore for effecting reciprocal motion of the heat engine piston. The output section includes an output bore receiving an output piston. A piston rod interconnects the heat engine piston to the output piston. A control controls the heat engine valve assemblies to operate the heat engine section in accordance with a desired output from the output section. The heat source may comprise the burning of a petroleum product, a solar heat source, geothermal heat source or a byproduct heat source. The output may comprise a static or mobile air conditioning system or an electrical generator.
