ABSTRACT:
A closed circuit machine for converting thermal energy into work has a heating fluid circulating therethrough which constitutes a source of heat. The machine includes a tank adapted to hold liquid and traversed by a first coil for circulating the heating fluid. The coil has two ends which are attached to a basin containing liquid. A condenser is positioned above the tank and serves to condense the fluid in the gaseous state, thereby and serving as a cold source capable of removing heat from the tank via a thermally insulated pipe. A hydraulic motor is positioned in the lower portion of a liquid return pipe system which connects the condenser and tank. A Venturi tube is positioned around the condenser, which is coated with a spongy material. The spongy material is continuously humidified, and the combination of the humidified spongy material and the air moving within the Venturi tube accelerates evaporation and therefore the amount of condensed liquid leaving the condenser. The potential energy of this liquid, in turn, is used to operate the motor.
