Abstract
A Stirling engine power generation system comprises a first gas fired Stirling engine driving a scroll compressor to provide heat to a second Stirling engine powered generator. The second Stirling engine is partially submersed in a heat transfer medium that is heated by heat transfer fluid compressed by the Stirling scroll compressor and excess heat from gas firing. The invention further comprises a cam drive system with spherical cam followers, and multiple electrical generators.

An improved electrical power generation system comprising:
- a first Stirling cycle engine having at least one piston driven by a hot gas, said first Stirling cycle engine also having an outlet air duct;
- a scroll compressor driven by said first Stirling cycle engine for compressing a heat transfer fluid;
- an insulated reservoir containing a heat transfer medium and a closed-loop heat transfer coil containing said heat transfer fluid submersed in said heat transfer medium;
- a second Stirling cycle engine having at least one piston driven by expansion of said heat transfer medium and a housing enclosing said second Stirling cycle engine and said insulated reservoir, said housing in fluid communication with said outlet air duct of said first Stirling cycle engine;
- and
- a generator having a driven shaft for producing electrical power operatively coupled to said second Stirling cycle engine.
