First spray device is coupled with the first chamber to heat or cool the first space in the first chamber. Second spray device is coupled with the second chamber to heat or cool the second space in the second chamber. At least one of the heating and cooling of the first space may cause at least one of a compression or expansion of the second space, which may drive a power-extraction unit coupled with the second chamber.

Further embodiments including fossil fuel energies.

The present disclosure relates to a system for storing and time shifting at least one of excess electrical power from an electrical power grid, excess electrical power from the power plant itself, or heat from a heat generating source, in the form of pressure and heat, for future use in assisting with a production of electricity. An oxy-combustion furnace is powered by a combustible fuel source, plus excess electricity, during a charge operation to heat a reservoir system containing a quantity of a thermal storage medium. During a discharge operation, a discharge subsystem has a heat exchanger which receives heated CO.sub.2 from the reservoir system and uses this to heat a quantity of high-pressure, supercritical CO.sub.2 (sCO.sub.2) to form very-high-temperature, high-pressure sCO.sub.2 at a first output thereof. The very-high-temperature, high-pressure sCO.sub.2 is used to drive a Brayton-cycle turbine, which generates electricity at a first output thereof for transmission to a power grid. The Brayton-cycle turbine also outputs a quantity of sCO.sub.2 which is reduced in temperature and pressure to a heat recuperator subsystem. The heat recuperator subsystem circulates the sCO.sub.2 and re-heats and re-pressurizes the sCO.sub.2 before feeding it back to the heat exchanger to be even further reheated, and then output to the Brayton-cycle turbine as a new quantity of very-high-temperature, high-pressure sCO.sub.2, to assist in powering the Brayton-cycle turbine.

A system for the generation of mechanical or electrical energy from heat energy, where increasing a height or pressure in a liquid chamber of the system containing a liquid increases an efficiency of the system up to a hundred percent or increases such efficiency until a critical temperature or pressure of the vapor (gas) is reached at the bottom of liquid chamber or in the boiler of the system depending upon the increment in height, pressure and the type of liquid used in the system. An increase in height of the system for such increased efficiency can be adjusted to a smaller height by maintaining a series of liquid and gas chambers where the vapor flows through the series of chambers or by adding pressure valves. The heat energy from high to low temperature sources can be convened to mechanical and electrical energy.

A power generation device and method using organic working fluid for circulation without pump and valve are invented, the principle is able to be called flash jet natural cycle. The flash injection tube, the magnetic sphere motion tube and the storage tank are connected to form the main loop. The finned tube and the storage tank are connected to form the cooling loop. The working fluid is heated in the flash injection tube by low-temperature heat source, and is cooled in the finned tube by air or water. The gravity and flash force jointly drive the flash jet natural cycle. The lower magnetic ball acts as a one-way valve for supplying liquid to the flash injection tube. The upper magnetic ball acts as a valve and a rotor driven by the flash force and gravity to move linearly and produce electricity.

A stand-alone long-distance closed-loop heat energy capture, conveyance, and delivery system, comprises three closed-loop modules in serial communication. The first module is in communication with a first closed-loop piping infrastructure interconnected with a source of heat energy, and has a LBP liquid circulating therein whereby the LBP liquid is converted into its gas phase when flowing through the source of heat energy thereby capturing a portion of heat energy therefrom, and is converted into its liquid phase when flowing through a first heat exchanger that transfers the captured-heat energy to a second closed-loop piping infrastructure wherein also is circulating a LBP liquid. The second closed-loop module may extend for long distances. The captured-heat energy in the second module is transferred to a third closed-loop piping infrastructure wherein is also circulating a LBP liquid. The captured-heat energy is transferred from the third module to a delivery site.
