Abstract
Abstract A heat engine consisting of a hermetically vapor vacuum sealed container and a heat-transfer fluid circuit, the fluid circuit including a heat source such as a solar heat collector. The engine employs as a working fluid a liquid with a low boiling point in the container, the heat transfer circuit passing through the lower portion of the container so that heat is conducted therefrom to the working fluid, causing bubbles to be generated therein. The bubbles flow upwardly and drive a turbine assembly mounted in the upper portion of the container. The turbine assembly is magnetically coupled to an external load device. The top of the container consists of a condenser exposed to ambient temperature wherein the bubbles are condensed and returned to a liquid state.
