An energy storage and retrieval system including an air chamber, a first air compressor operating with Heat Transfer Liquid (HTL-compressor) connected to the air chamber, a second turbine, operating with Heat Transfer Liquid (HTL-turbine) connected to the air chamber, accepting compressed air from the air chamber and producing work. Related apparatus and methods are also described.

Heat-transfer-liquid-operated turbine and compressor

A method for converting heat to mechanical work includes providing incoming heat transfer liquid (HTL) at a first temperature to a plurality of mixing chambers, providing incoming compressed gas at a second temperature to the plurality of mixing chamber, enabling the gas and the HTL to mix, producing a gas-and-HTL mix, enabling the HTL in the gas-and-HTL mix to heat the gas and isothermal expansion of the gas in the gas-and-HTL mix, limiting volume of the gas-and-HTL mix, thereby increasing pressure of the gas and causing acceleration of a flow of the gas-and-HTL mix, causing the gas-and-HTL mix to eject through a plurality of nozzles, thereby converting the heat of the HTL to kinetic energy to cause movement of the plurality of nozzles; and using the kinetic energy to produce mechanical work.

Heat engine

A method for converting heat to mechanical work including providing incoming heat transfer fluid (HTF) at a first temperature to a mixing chamber, providing incoming compressed gas at a second temperature to the mixing chamber, enabling the gas and the HTF to mix, producing a gas-and-HTF mix, enabling the HTF in the gas-and-HTF mix to heat the gas and isothermal expansion of the gas in the gas-and-HTF mix, limiting volume of the gas-and-HTF mix, thereby increasing pressure of the gas and causing acceleration of a flow of the gas-and-HTF mix, causing the gas-and-HTF mix to eject through a nozzle, thereby converting the heat of the HTF to kinetic energy, and using the kinetic energy to produce mechanical work. Related apparatus and methods are also described.
