Image Number 3 for United States Patent #4683721.

A heat engine is provided with twin crankshafts and coil shaped power elements mounted between each of two crankshafts. Each power element moves upward and downward, parallel with the surface of a tank of hot water, in which the engine is partially submersed, so that every part of the power element is allowed to remain submersed in the hot water for the same time interval so as to achieve maximum rotating power.
