Provided is a power generation system with which it is possible to perform efficient power generation. The power generation system comprises: an evaporation chamber; a reciprocal heat-insulating cylinder provided with a forward-side expansion chamber and a backward-side expansion chamber; an operating fluid supply/ejection means which performs a supply flow passageway forming operation and an ejection flow passageway forming operation in an alternating and reciprocal manner; a heat-insulating expansion chamber; a liquefied operating fluid recirculating means; and a compression/liquefaction recirculating means. The heat-insulating expansion chamber may be provided separately on both the ejection flow passage downstream side of the forward-side expansion chamber and on the ejection flow passage downstream side of the backward-side expansion chamber.

An arrangement having multiple heat exchangers and a method for evaporating a working fluid by transferring heat from a heat source medium is described herein. The arrangement is used in connection with a system for recovering energy from waste heat in a thermodynamic cycle, in which the waste heat is used as the heat source medium. Each heat exchanger has a heat source medium through-passage separated from a working fluid chamber are serially interconnected in a ring arrangement. A supply line is provided between the heat source medium through-passages of any two serially consecutive heat exchangers in the ring arrangement, which can be connected selectively to the inlet of the heat source medium through-passage of each heat exchanger. Further, a discharge line for the heat source medium is provided, which can be connected selectively to the outlet of the heat source medium through-passage of each heat exchanger.

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.

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.
