Abstract: Hydraulic air compressor and fuel fired turbine apparatus disposed in a vessel or ship includes a hydraulic compressor having an air intake disposed above the water intake for entraining air in falling water, and the output of the hydraulic compressor is used as a compressed air source for turbine apparatus. The turbine apparatus includes a regenerator for heating the incoming compressed air output from the hydraulic air compressor. The hydraulic air compressor includes, in one embodiment, pump elements for providing a flow of water for when the ship or vessel is not moving and a flow of air to be entrained and compressed.

Abstract: Hydraulic air compressor and turbine apparatus includes a hydraulic air compressor having an air intake disposed above the water intake for entraining air in falling water, and the output of the hydraulic air compressor is used as a compressed air source for a turbine. The turbine apparatus includes a regenerator for heating the incoming compressed air output from the hydraulic air compressor. The hydraulic air compressor may include a pump for providing a flow of water for entraining and compressing air to provide a closed cycle system, and it may include an air pump or fan to increase the amount of air entrained in a given flow of water. Several different structures for negating a loss of water velocity are also disclosed, and several different turbine systems are disclosed.

Abstract: Heating and cooling apparatus includes an evaporative cooler and a heat pump connected to each other and to a common duct system for utilizing the attributes of both systems for efficient heating and cooling. The evaporative cooler may be used to cool a structure directly or it may be used to cool the condenser coils of a heat pump. The evaporative cooler may also be used to cool attic space. The evaporative cooler and the heat pump are disposed adjacent to each other and are connected by an interface adapter, and the interface adapter is in turn connected to attic space through which air from the attic flows, particularly to assist the heat pump in the heating mode.

Abstract: Energy amplifier apparatus includes a pair of vertically extending concentric cylinders, with air entrained in water flowing downwardly through the inner cylinder to a separator where the air is separated from the water. The falling water compresses the entrained air and a separator in the inner cylinder is used to separate the compressed air from the water, with the water flowing upwardly between the inner and outer cylinders and the compressed air flowing upwardly in a separate conduit from the upper portion of the inner cylinder.
