ABSTRACT:
An engine apparatus is adapted to operate upon partial immersion in a heated liquid in a liquid reservoir. A movably mounted frame is mounted to a fixed frame and located adjacent the liquid reservoir in a manner that heat exchangers attached to the movable frame are successively passed into the liquid of the liquid reservoir. The heat exchangers are connected in pairs on opposite sides of the movable frame and contain a low boiling point liquid therein. Each heat exchanger of each pair is connected to the other through a pair of drive cylinders, so that the expansion of the fluid in the heat exchanger passing through the liquid reservoir and the simultaneous contraction of fluid in the heat exchanger that has left the reservoir expands and contracts the drive cylinders to operate the engine. The engine will operate from a low temperature heated liquid such as may be provided by solar panels or water heat from power plants.
