摘要： Traditional power generation with a turbine may be inefficient, costly or inconvenient. The improvement disclosed herein involves the use of two fluids. A pressurizing fluid is vaporized, pressurized and fed into a pressure cylinder holding a liquid working fluid. The pressurizing fluid forces the working fluid out of the pressure cylinder and through a liquid turbine to generate electricity or perform work. The working fluid is recycled from the turbine into another pressure cylinder for re-use. The pressurizing fluid is condensed and then also recycled back to the evaporator where it is vaporized and pressurized again. Use of a liquid rather than gas turbine makes for improved efficiency and lower cost. The use of a separate pressurizing fluid, which may be volatile, allows for convenient use where the temperature of the thermal source is limited.

摘要： The invention relates to a method of fluid exchange using a separation apparatus, in controlled fluid communication with an inlet and an outlet. Opening of the inlet enables fluid communication with the separation apparatus, exchange of fluid (a “first fluid exchange”) of a first volume of fluid, sealing/closing preventing further fluid communication. Opening of the outlet to be in fluid communication with the separation apparatus enables exchange of fluid (a “second fluid exchange”) through the open outlet of a second volume of fluid. In the method, the outgoing volume of fluid and the incoming volume of fluid in each exchange are substantially similar and there is substantially no loss of pressure by virtue of the exchange. The invention also relates to a separation apparatus, including a separation chamber and a control system.

摘要： The fluid expansion engine uses a liquid working fluid contained by primary pressurized cylinders. A heat exchange system alternately cycles hot and cold through the primary pressurized cylinders. As a result, the liquid working fluid in the cylinders reciprocally expands and contracts. The work done by the fluid expansion engine is extracted via a hydraulic pump and gearbox connected to secondary pressurized cylinders attached to the primary pressurized cylinders.

摘要： A generator comprising heat differential, pressure, and conversion modules, and a heat recovery arrangement; the differential module comprising a first high temperature reservoir containing a work medium at high temperature, a second low temperature reservoir containing a work medium at low temperature and a heat mechanism in fluid communication with the reservoir(s). The heat mechanism maintains a temperature difference therebetween by providing heat to and/or removing heat from the reservoirs; the pressure module comprises a pressure medium in selective fluid communication with the reservoirs for alternately performing a heat exchange process with the work medium. The pressure medium fluctuates between a minimal and maximal temperature corresponding to the high and low temperatures of the work medium; the conversion module utilizes temperature changes of the pressure medium for production of output energy; the recovery arrangement absorbs heat from the pressure medium and provides heat to the differential or pressure module.

摘要： A steam engine has a fluid container, a heating device and a cooling device provided at the fluid container for heating and cooling working fluid filled in the fluid container, so that a part of the working fluid is heated and vaporized to move the liquid-phase working fluid in one direction. When the vaporized steam is cooled and liquidized, the pressure of the working fluid in the fluid container is decreased, to thereby move the liquid-phase working fluid in the backward direction. Kinetic energy is thereby generated by using the back and forth movement of the working fluid. The heating device has multiple through-holes, through which the working fluid flows and heated by a heating surface (an inner surface of the through-holes) of the heating device, wherein a diameter “d” of the through-hole is made almost equal to or smaller than a depth of heat penetration “δ”, which is determined by the following formula: δ=√{square root over (2a/ω)} wherein “a” is a heat diffusivity of the working fluid, and “ω” is an angular frequency of the working fluid during the working fluid is periodically moved back and forth.
