Provided here is an architectural plan (the solution) for the restoration of the terminal lake, the Salton Sea, an area of prevalent geothermal sources. It includes division of the Lake into three sections, preventing pollution of the Lake from nearby farmlands and importing seawater in central section with pipeline system; providing condition for tourism, and wildlife sanctuary; generating electricity by harnessing hydro, solar, and geothermal energy; and producing potable water and lithium as byproducts. Also includes a system and method for harnessing geothermal energy for generation of electricity by using complete closed loop heat exchange systems combined with onboard drilling apparatus. The system includes several devices operating separately in many different applications in energy sectors, Also, included is alternative use for the In-Line-Pump for marine crafts propulsion.

A heat pipe or a bundle of heat pipes for transporting geothermal heat in a well is provided. As the temperature rises at one end of the heat pipe, the operating fluid turns to a vapor which absorbs the latent heat. The hot vapor within the heat pipe flows to the cooler end of the heat pipe where it then condenses and releases the latent heat. The condensed fluid then flows back to the hot side of the heat pipe and the process repeats itself.

A geothermal heating and cooling system that uses a water source to provide a heat transfer medium is provided. Elements of the system may include a water source, one or more circulation loops coupled to the water source, a heat exchanger and/or heat pump, and/or a monitoring component configured to monitor for conditions within the system, including leak integrity and water quality.

A geothermal heat mining system can operate within a single primary borehole in a geothermal reservoir. A primary fluid loop can include a cold working fluid line leading into the primary borehole and a hot working fluid line coming out of the primary borehole. A secondary fluid loop can be located down the primary borehole, where the secondary fluid loop is in thermal contact with the geothermal reservoir and is entirely subsurface. A downhole heat mining device can control a rate of heat transfer from the secondary fluid loop to the primary fluid loop by selectively controlling fluid flow through the primary fluid loop, the secondary fluid loop, or both.

A geothermal pipe collector is provided. The geothermal pipe collector is made from a polymer composition comprising: more than 50 wt % polyethylene, 0.1 wt %-35 wt % talc and 0.5 wt %-10 wt % carbon black.

An energy transfer unit for a geothermal system includes an outer housing. A heat exchanger is located within the housing. An inlet pipe extends from the housing to the heat exchanger to convey heat transfer fluid to the heat exchanger and an outlet pipe extends from the housing to the heat exchanger to convey heat transfer fluid from the heat exchanger.

A scale suppression apparatus capable of suppressing in a low-priced manner the generation of silica-based scale and calcium-based scale in the influent water containing at least a silica component and a calcium component, a geothermal power generation system using the same, and a scale suppression method are provided. The scale suppression apparatus includes a chelating agent and alkaline agent addition unit injecting liquid containing a chelating agent and an alkaline agent into a pipe arrangement through which influent water such as geothermal water or the like flows, and a controller controlling a pump and a valve of the chelating agent and alkaline agent addition unit. The controller controls the injection of the chelating agent and the alkaline agent and stops of the injection based on the signal output from a scale detection unit for detecting a precipitation state of the scale.

Embodiments of the invention utilize the geothermal energy exchanger and battery (GEEB) to recover and store thermal energy from the dwelling, from the ground, and from the Earth's atmosphere, reuse the thermal energy in another season of the year, and consume electrical energy to heat and cool the structure at electrical Off Peak time periods. The GEEB may be constructed of a compact steel, ribbed and waterproof permanent container that is set at a depth beneath the surface of the ground where the normal soil temperature is virtually constant year round. The container can then be encased in poured concrete, with the exception of piping or conduits. The container is then filled with a heat transfer fluid so that the entire thermal mass of the GEEB and heat transfer fluid reaches the ambient ground temperature and efficiently couples the load and source sides of a heating and cooling system.
