ABSTRACT:
A hermetically sealed Stirling engine driven generator system with a rotating generator, self lubricated bearings using PTFE filled polyimide, a fibrous ceramic piston dome, and flame sprayed ceramic and PTFE coating on the pistons, which allow an oil free system. A brushless self starting system is also used as an alternator. A simple working gas pressure control system uses the housing for the generator and the crankcase as a reservoir for working gas allowing a single valve working in conjunction with a small compressor to regulate the pressure of the working gas.
