Abstract: A closed loop system for generating mechanical energy at high efficiencies from hydrogen, fossil fuels, bio-fuels, solar or other renewable and recoverable energy sources. The system can have a heating source, a superheater, an expander, a receiver, a condenser, vacuum pump, or absorber, a desorber, and regenerator with pumps and controls. The heating source and superheater are used to heat a working fluid (including ammonia, other refrigerants, a combination of refrigerants, or steam). A positive displacement liquid/vapor expander expands the heated working fluid to the near saturated or saturated state utilizing a reduced pressure, low-pressure, or sub-atmospheric exhaust sink. A condenser, vacuum pump, or absorber is used to generate the reduced pressure, low pressure, or sub-atmospheric sink. The desorber is used to reconstitute inlet vapor (for reuse) and the regenerator recovers heat generated by the process.

Abstract: A combustion powered cooling system (10, 100) includes a power loop (12, 102) and a cooling loop (14, 104). Heat produced by combustion is used to produce superheated steam in a steam generator (18). The steam is used to move a reciprocating steam piston (26) in a power unit (16). Power is transferred from the steam piston through a energy transfer mechanism (44) to a compressor piston (40) in the cooling loop. Refrigerant material in the cooling loop is used to provide air conditioning for a residence or other facility through a chilled water circuit (60). The system is also operative as a heat pump for heating a residence or other facility.

Abstract: A high efficiency heat transfer system includes a power circuit (350) and heat pump circuit (352). Each circuit having a working fluid flowing therein. In the power circuit, a heater (354) vaporizes the working fluid which is periodically delivered and exhausted through a valve assembly (358) to a power unit (362). The power unit is also a compressor for the working fluid in the heat pump circuit. Fluid exhausted from the driven section of the power unit is passed to a four-way valve (406) which selectively delivers the working fluid to an interior coil (416) or an exterior coil (408) to heat or cool an area. In extremely cold ambient temperatures, the area is heated directly from the power circuit using a by-pass exchanger (428).

Abstract: A high efficiency pool heating system (10) includes a power circuit (12) and heat pump circuit (14). Each circuit having a working fluid flowing therein. In the power circuit, a heater (16) vaporizes the working fluid which is periodically delivered and exhausted through a valve section (32) to a driving section (28) of a power unit (26). The driving section drives a driven section (30) which operates as a compressor for the working fluid in the heat pump circuit. Fluid exhausted from the driven section of the power unit is passed to a first portion (48) of a heat exchanger (46) which is in fluid communication with the water of a pool. In the heat exchanger, the working fluid in the power circuit is condensed to a liquid. Thereafter, the liquid is passed through the power circuit back to the heater where it is again vaporized.

Abstract: A high efficiency solar powered water pumping system (10) includes a solar collector (12) for heating and vaporizing a working fluid. The vaporized working fluid is passed to a motor and valve assembly (20) that alternatively delivers the working fluid to a power unit (22) and exhausts the working fluid from the power unit to a condenser (32). The power unit has a driving member (128) that moves up and down driving a sucker rod (194) of a sucker rod assembly (26) which raises water from a well in the earth. The water pumped from the ground passes through a tube (36) in the condenser. The working fluid which has been exhausted from the power unit into the condenser, condenses to a liquid. The liquid working fluid is then pumped from the condenser by a positive displacement pump (40) and is returned to the solar collector to repeat the cycle.
