ABSTRACT:
A reciprocating micro heat engine for electrical and mechanical power generation is disclosed The micro heat engine uses a reciprocating free piston that is driven by a periodic combustion process, and is implemented using micromachining technology. In the application of electrical power generation, the mechanical and electrical functionality of the engine are highly integrated; i.e., the same piston performs both the fuel-to mechanical energy conversion as well as the mechanical-to-electrical energy conversion.
