Abstract: The present invention is a prime mover with recovered energy driven compression for stationary and motor vehicle application. Efficient low compression operation, especially beneficial to small gas turbines, is enabled with either ambient or cryogenic intake air. Recovered energy, liquefied air cooling and re-liquefaction of air by a cryogenic sink minimize motive fluid compression work of a jet compressor driving exhaust gas recirculation. Regenerative heat exchanger terminal temperature difference relative to turbine temperature drop and heat exchanger surface area are reduced.

Abstract: A building energy recovery system having at least one wind drive mounted to the building structure proximate to the roof junction, a generator and an electrical output. The wind drive includes a radial flow wind turbine having a rotor, a rotatable shaft of the rotor, an open windward facing air intake duct, and a side facing air discharge opening disposed perpendicular to the rotatable shaft of the rotor. The intake duct is in communication with a wind blowing toward the front wall and the discharge opening is in communication with a wake region adjacent to the discharge opening and induced by a wind flowing behind the roof junction.

Abstract: A regenerative heat exchanger for transferring heat from the exhaust gas to the intake working fluid of a prime mover. Application includes gas turbines for both motor vehicles and distributed electric generation. The heat exchanger employs a rotating matrix, which circulates through working fluid exhaust and intake channels while absorbing and rejecting heat between the two channels. Features include corrugated tubes for enhanced heat transfer, minimally welded low stress construction, quick-detach assembly of standard components, and purge flow sealing using recovered heat. Effectiveness exceeding 95% increases thermal efficiency of low-pressure ratio gas turbines.

Abstract: A prime mover with recovered energy driven compression for stationary and motor vehicle application. Efficient low compression operation, especially beneficial to small gas turbines, is enabled with either ambient or cryogenic intake air. Two features, exhaust gas recirculation by a jet-compressor and a heat of fusion sink to liquefy motive air to the jet-compressor, decrease regenerative heat exchanger terminal temperature difference relative to turbine temperature drop in low pressure operation while reducing heat exchanger surface area.

Abstract: A gas turbine prime mover for stationary and motor vehicle application. The gas turbine employs jet compression energized by a pressurized motive fluid to entrain a depressurized suction fluid from the turbine discharge. Combined suction and motive fluids circulate through the combustor or other heating source and the turbine while motive fluid, separated from the turbine discharge, preheats pressurized motive fluid in a heat recovery recuperator or regenerator. Additional features include recovery of heat loss from heating source loss and sub-ambient compression cooling of motive fluid. Cycle efficiency of 70% is attained.

Abstract: A regenerative heat exchanger for transferring heat from the exhaust gas to the intake working fluid of a prime mover and from the pressurized working fluid to the exhaust vapor of a heat pump. Application is especially useful in a system in which liquid air or nitrogen made by a heat pump provides compression cooling for a gas turbine prime mover. The heat exchanger employs circulating element heat transfer surface such as wire belts or ceramic balls, which circulate in turn through working fluid exhaust and intake channels while absorbing and rejecting heat between the two channels. Effectiveness exceeding 98% increases thermal efficiency of small low-pressure ratio gas turbines.
