ABSTRACT:
A method of generating power is disclosed wherein a liquid having a boiling point near the ambient temperature when it is under atmospheric or moderately higher pressures, preferably propane, isobutane, Freons or ammonia, is placed in a pressure vessel, heat energy is gathered from a naturally occurring heat sources, such as by solar collectors or from hot springs, geothermal or other heat sources, and transmitted through conduction heat pipes to the liquid in the pressure vessel, and the liquid is thereby heated to the boiling point and vaporized. When a liquid is vaporized, its volume expands by several hundred times, creating a pressure sufficient for driving motors. This invention can be used in automobiles, motorcycles, generators, ships, homes, factories, and other suitable places to drive motors, thus reducing the use of petrochemical fuels.
