A system suitable for extracting power directly from the main shafts of slow-moving mechanical systems. The system has a closed gas circuit having a lower-pressure (LP) side and a higher-pressure (HP) side. The LP side is at a pressure substantially greater than atmospheric pressure. The system includes primary compressors coupled to the wind turbines, thermal stores coupled to heat-exchangers on both the LP and HP sides of the closed gas circuit, a secondary motor-compressor set and an expander-generator set. The system allows some degree of independence between the input power resource and the output power. When substantial wind power is present and the demand for electrical power is weak, this system can export a fraction of the energy captured and store the rest. When the wind resource is low, the system can export more power than is being collected by drawing energy from the thermal stores.

A turbopump system includes a pump portion including a housing having a pressure release passageway disposed therein. The pump portion is disposed between a high pressure side and a low pressure side of a working fluid circuit. A drive turbine is coupled to the pump portion and configured to drive the pump portion to enable the pump portion to circulate a working fluid through the working fluid circuit. A pressure release valve is fluidly coupled to the pressure release passageway and configured to be positioned in an opened position to enable pressure to be released through the pressure release passageway and in a closed position to disable pressure from being released through the pressure release passageway.

A cogeneration system for generating electricity and process steam. The system includes an internal combustion engine having a shaft and a cooling system comprising a cooling fluid adapted to circulate through the engine and to cool the engine under conditions of nucleate boiling in which at least 10 percent of the coolant exits the engine in a vapor phase. It includes a vapor separator adapted to separate the coolant that exits the engine into a vapor phase coolant and a liquid phase coolant. The engine shaft drives an electric generator to provide electric power. A hot vapor line directs hot vapor exiting the vapor separator to a hot vapor process load. A coolant circulation pump is provided to force the cooling fluid through the engine, and a hot water line is provided to return hot water exiting the vapor separator to the coolant circulation pump. In preferred embodiments the system further includes an excess steam condenser for to collecting and condensing excess steam not needed by the hot vapor load, a condensate return tank adapted to store condensate from the hot vapor load and the excess steam condenser, and a condensate return line adapted to return condensate to the coolant recirculation pump.

The present invention provides a power device generating greater propelling force and finds that traditional power devices do not include all propelling forces based on the fundamental core propelling force source problem. External pressure is guided to the traditional power devices since the inner speed is higher the outer speed, power consumption for overcoming fluid resistance is high, and mutual contradiction results are obtained. The unique difference between the present invention and general common sense lies in opposite fluid pressure directions; inner fluid channels and outer fluid channels with higher flow speeds are formed to generate pressure differences which guides the fluid pressure to the outside and serve as propelling force, and thus the present invention creatively finds three propelling force sources, two lifting force or propelling force sources of helicopters or airplanes driven by propellers and two propelling force sources for sufficient burning of fuel in combustion chambers of engines.
