Abstract: At least one of a heat-driven power generation system, an HVAC system, a system requiring heat rejection from its working fluid, and any object where cooling is advantageous where the portion of at least one of the exterior working fluid containment tubing and the exterior surface area exposed to air that is used for heat rejection is coated with a special coating designed to enhance heat rejection to the exterior air and/or space with minimal interference from air molecules in the earth's atmosphere.

Abstract: A renewable energy, single well, primarily self-flow, geothermal heat/power production system that acquires naturally occurring sub-surface geothermal heat to heat water and/or produce mechanical/electrical power using a heat exchangers or a turbine/generator. The sub-surface structures defining a working fluid flow path may be insulated, such as with vacuum insulation, to increase system efficiency and ensure a substantially self-generating working fluid flow.

Abstract: A single closed loop direct exchange geothermal power production system that utilizes a refrigerant working fluid in at least one of three primary designs to generate electrical power from deep wells: with a first version of a direct exchange geothermal power generating system operating primarily on refrigerant vapor pressure; with a second version of a direct exchange geothermal power generating system operating primarily on liquid refrigerant gravitational pressure; and with a third version of a direct exchange geothermal power generating system operating primarily on both liquid refrigerant gravitational pressure and refrigerant phase change/expansion from a liquid to a vapor state.
