A solar collector (1) with parabolic mirrors (2) feeds the prim coil (7) of a heat sotre (6) mfd of concrete, Al or ceramic in an insulating jacket with an electric heater winding (9) or natural gas or butane burner. The sec coil (8) is coupled in another closed circuit to a heat exchanger (12) from which a working fluid is circulated through a Stirling engine (15) driving an output shaft (16) for propulsion or similar purposes. The store (6) contains eg oil with a high bpt and the working fluid may be C02, steam or a halogenated gaseous hydrocarbon. USE/ADVANTAGE - Esp for mobile (eg vehicular) or stationary electric current generators. Environment-friendly appts producing no exhaust gas uses energy store chargeable from external sources or mobile solar collectors.
