ABSTRACT:
A generator having a tubular gear made of shape memory alloy in sheet form loatingly supported for rotation about an axis fixedly spaced from the rotational axis of a roller gear. The tubular gear is sequentially deformed by exposure to a geothermal heat source and meshing engagement with the roller gear. Such sequential deformation of the tubular gear is controlled by temperature differential to induce and sustain rotation of the gears in response to which the heat energy is converted into electrical energy.
