ABSTRACT:
A closed cycle solar operated power generator is provided in which a tubular heat collector positioned concentrically within a transparent tube sealed at one end is radiantly heated and a compressor takes gas at low temperature and pressure and supplies it to the open end of the transparent tube at an elevated pressure. The compressed gas passes through the transparent tube outside of said tubular collector and then returns to the open end thereof inside of the tubular collector to a turbine positioned within a housing sealed to the tubular collector. The turbine exhaust passes through a heat exchanger to heat the compressed gases entering the transparent tube, and the cooled exhaust enters a conductive tube sealed at one end and having its open end sealed to the open end of the transparent tube. The conductive tube is cooled by conduction or radiation to further cool the exhaust which then returns to the compressor through a tubular compressor inlet to complete the closed cycle.
