A geothermal plant, for extracting energy from a geothermal reservoir located below the ocean bottom, includes a floating platform; a riser that extends from a well drilled into the geothermal reservoir, to the floating platform; an electrical pump having a mechanical actuation part located in a bore of the riser, and an electronic part located outside the riser, wherein the electrical pump is configured to pump a geothermal liquid from the geothermal reservoir to the floating platform; and a power plant located on the floating platform and configured to use a steam produced by the geothermal liquid to generate electrical power. The electrical pump is placed at a depth of the riser where the geothermal liquid is in a single-phase.

Fluid classes for use in energy recovery in well and geothermal environments for power production are disclosed. The fluids fall into the classes of fluids being capable of increasing thermodynamic efficiency of electricity and/or heat generation from a closed-loop geothermal system. Numerous methods are disclosed which exploit the thermodynamics of the fluids for optimum energy recovery.

A gravity-assisted heat pipe cooling source cold storage system and chiller set. The cold storage system includes a gravity-assisted heat pipe, a cold storage pool, a heat exchanging and cold condensing device, and a heat exchanger pipe. A lower end of the gravity-assisted heat pipe is arranged in the cold storage pool, and an upper end of the gravity-assisted heat pipe is arranged in the heat exchanging and cold condensing device. The heat exchanger pipe is buried underground, and includes a central pipe and a side pipe. Upper ends of the central pipe and the side pipes are communicated with an inlet and outlet of the heat exchanging and cold condensing device, respectively. Lower ends of the central pipe and the side pipes are communicated with each other. The system employs the heat exchanger pipe to provide a cooling source for the gravity-assisted heat pipe.

Environmental enhancement systems and methods are disclosed. The environmental enhancement system may include a ground source heat pump including a subsurface ground loop portion and a liquid supply system to apply liquid (e.g., wastewater) to soil that is proximate to the subsurface ground loop portion. Performance of the ground source heat pump is improved by increasing heat transfer between the ground loop portion and the soil that is proximate to the subsurface ground loop portion. A gas injection system may be used to inject a gas into the soil that is proximate to the subsurface ground loop portion thereby cooling the soil, liquid, and air at a surface of the soil.

A geothermal heat delivery system is provided for various residential applications, including heating driveways, paths, sidewalks, homes, roofs swimming pools, and commercial applications, including heating roadways, parkways, highways, airport runways, parking lots and sidewalks. A series of heat pipes are used to provide geothermal heat from a borehole to a structure or a surface, which can for example, melt precipitation on a road, driveway or roof.
