One embodiment of a heat engine machine enabling a user to convert heat sources into mechanical work or compressed air. The heat engine requires solar radiation and air. The thermodynamic cycle is quasi-isobaric, and comprise positive displacement compressors 16A & 16B, nozzle 30A, and turbine 18. Working fluid pressure lines 20, and storage fluid pressure lines 21 connect compressors 16A & 16B, air storage 21A, heat exchangers 20A & 21A, and nozzle 30A. The nozzle is De Laval shaped and has a valve that moves to throttle the rate of fluid expansion driving the turbine 18. The compressors 16A & 16B have directional control outlet valves, as well as intake control valves 31A and 31B. The heat sources include the following: recuperated waste heat 20A, regenerated heat of compression 21A, external heat absorber 14.
