Abstract

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.

First claim

What is claimed is:

1. A method for converting heat to mechanical work comprising:
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.

2. The method according to claim 1 , wherein the first temperature of the incoming HTL is greater than 90 degrees Celsius.

3. The method according to claim 1 , wherein the second temperature of the incoming gas is lower than the first temperature.

4. The method according to claim 1 wherein the gas is quasi-isochorically or isochorically heated by the HTL.

5. A method for converting heat to mechanical work comprising:
providing incoming heat transfer fluid (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, wherein the plurality of nozzles is mounted on a turbine to result in its rotation; and
using the kinetic energy to produce mechanical work.
