A metal object 1, which may be part iron, aluminium, copper or steel, is heated by a means which may be electrical 2. A fluid, which may be air 3, is heated within an internal chamber 4. The heated fluid revolves a turbine 6 connected to an electrical generator 5. Part of the electrical or mechanical energy then drives an electrical means which may be a compressor 7 which may be powered by an electric motor 8 to resupply the working fluid to the heat transfer means. Power may be controlled by a controller 9 for the electric motor 8 driving the compressor 7. The metal object may be insulated by means of a vacuum. The electric motor powering the compressor may also be powered by a cell or battery or capacitor or solar panel. |
