Robert Stirling was a Scottish minister who invented the first practical example of a closed cycle air engine in 1816, and it was suggested by Fleeming Jenkin as early as 1884 that all such engines should therefore generically be called Stirling engines. An important consequence of this ideal cycle is that it does not predict Carnot efficiency. Particular details of the receiver are not important insofar as general principles of the present invention are concerned since the receiver is essentially conventional. On top of that you need a low torque alternator-generator with cogging effect at minimum or zero.

He called this cycle the ‘pseudo-Stirling cycle’ or ‘ideal adiabatic Stirling cycle’. Rider’s, Robinson’s, or Heinrici’s (hot) air engine.

The usual tendency to stirling engine design has been to use high temperatures and pressures in order to pursue performance and specific power competitive with conventional systems. This approach results in problems of special materials and advanced technologies. The reflective mirrors are formed into a parabolic shape using stamped sheet metal similar to the hood of a car.  A Stirling engine can function in reverse as a heat pump for heating or cooling. Additionally, the advent of transistor radios and their much lower power requirements meant that the original rationale for the set was disappearing. The revised design also has fewer mirrors — 40 instead of 80. When the working gas contacts the cold side, its pressure drops below atmospheric pressure and the atmosphere pushes on the piston providing more energy to the generator.
