Abstract: In combination, a generally conical structure for collecting air and providing a confined space for solar heating of such air, connected, at the upper end of the conical structure, with a vertically placed electric generator through which the solar-heated air passes. The combination utilizes the principle that the heated air expands and becomes lighter, causing it to be displaced by the cooler, atmospheric air at the bottom of the air collecting structure, creating an upward flow of the heated air through the electric generator. The generator is unique for the purpose in that the generator rotor and turbine turn in concert and are a single unit.
