Patent number: 10400635Abstract: An improved heat engine that includes an organic refrigerant exhibiting a boiling point below ?35° C.; a heat source having a temperature of less than 82° C.; a heat sink; a sealed, closed-loop path for the organic refrigerant, the sealed, closed-loop path having both a high-pressure zone that absorbs heat from the heat source, and a low-pressure zone that transfers heat to the heat sink; a positive-displacement decompressor providing a pressure gradient through which the organic refrigerant in the gaseous phase flows continuously from the high-pressure zone to the low-pressure zone, the positive-displacement decompressor extracting mechanical energy due to the pressure gradient; and a positive-displacement hydraulic pump, which provides continuous flow of the organic refrigerant in the liquid phase from the low-pressure zone to the high-pressure zone, the hydraulic pump and the positive-displacement decompressor maintaining a pressure differential between the two zones of between about 20 to 42 bar.Type: GrantFiled: July 25, 2017Date of Patent: September 3, 2019Assignee: Heat Source Energy Corp.Inventors: Keith Sterling Johnson, Corey Jackson Newman

Patent number: 10323545Abstract: A method for generating power from a heat source includes mixing a refrigerant in a liquid phase with a lubricating oil, heating the mixture to evaporate the refrigerant, mixing the heated mixture with additional refrigerant in a superheated phase, and atomizing the lubricating oil to disperse the lubricating oil within the refrigerant. The atomized lubricating oil and the refrigerant are passed through a decompressor to generate an electrical current. The refrigerant may be an organic material having a boiling point below about ?35 C. Related systems and heat engines are also disclosed.Type: GrantFiled: May 25, 2016Date of Patent: June 18, 2019Assignee: Heat Source Energy Corp.Inventor: Keith Sterling Johnson
