ABSTRACT:
An engine powered by low boiling liquid and adapted to operate upon partial immersion in a heated liquid, which may be solar heated, is provided by a circular train of tubular compartments in which adjacent compartments are sealed to interconnectors and the train is tied to a central axle so that rotation of the train will rotate the axle. The interconnectors have an opening and a tube extending forwardly into the leading compartment, and one way valves permit rearward movement through the tube while preventing forward movement through the tube, and this allows liquid in the bottom compartment to be pumped rearwardly to a descending compartment to power the engine while liquid in an ascending compartment drains rearwardly to minimize the drag on the engine.
