Abstract: A device which can convert energy of latent heat at an ambient temperature, without a change of temperature, to power to kinetic energy of motion and levitation of mass, by a manufactured molecular force which acts only in one direction.

Abstract: A two-phase thermal energy conversion system employs an evaporable liquid such as water, and a gas which is not liquefiable within the operating temperature and pressure ranges, such as air. The water and air are mixed and one of the two or both are heated so that the water evaporates and is absorbed by the air to result in a pressure increase. The increase of pressure or volume can be converted into mechanical energy by a prime mover such as a turbine or reciprocating piston engine. The heat of condensation is utilized and converted into mechanical power while the temperature and pressure are reduced. The liquid, such as water, may be below its boiling point. If the water consists of salt water, fresh water is derived as a condensation product from the prime mover.

Abstract: A continuous flow, evaporative-type thermal energy recovery apparatus comprises an evaporator unit to which are supplied continuous pressurized flows of hot water and air, and in which a portion of the hot water is evaporated into the air, preferably to completely saturate the air with moisture. Connected to receive the resulting flow of pressurized, water saturated air from the evaporator unit is a low pressure gas turbine, which is operated by such flow. Work is performed by expansion of the saturated air in the turbine, the work being converted, for example, to electricity by a generator connected in driven relationship with the turbine. The source of hot water may be a cooling system for cooling other apparatus or may, for instance, be a heat exchanger in which solar energy is used to heat water recirculated through the apparatus. Condensed water vapor from the turbine may also be recirculated.
