Abstract
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.

A method for converting heat to mechanical work comprising:
- providing incoming heat transfer fluid (HTF) 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 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 plurality of nozzles, thereby converting the heat of the HTF to kinetic energy to cause movement of the plurality of nozzles;
- and
- using the kinetic energy to produce mechanical work;
- wherein the HTF comprises a fluid selected from a group consisting of:
- water, oil, molten salt and molten metal.
