摘要： A geothermal system is used for obtaining heated heat transfer fluid, such as steam, via heat transfer with an underground reservoir of magma. The geothermal system includes a wellbore extending between a surface and into an underground chamber formed in a reservoir of magma. The chamber may be formed by injecting a fluid at an increased pressure into underground magma to form a cavity that acts as the underground chamber.

摘要： A method for controlling temperature maxima and minima from the heel to toe in geothermal well lateral sections. The method includes disposing at least a pair of wells proximately where thermal contact is possible. Working fluid is circulated in one well of the pair in one direction and the working fluid of the second well is circulated in as direction opposite. to the first. In this manner temperature equilibration is attainable to mitigate maxima and minima to result in a substantially more uniform temperature of the working fluids in respective wells and the rock formation area there between. Specific operating protocol is disclosed having regard to the temperature control for maximizing thermal energy recovery.

摘要： Thermal energy is extracted from geological formations using a heat harvester. In some embodiments, the heat harvester is a once-through, closed loop, underground heat harvester created by directionally drilling through hot rock. The extracted thermal energy can be converted or transformed to other forms of energy.

摘要： An assembly and process for forming a two stage extruded pipe having a central inner sleeve and a pair of outer attached lobes. The central sleeve shaped (also termed a grout receiving tube) is produced in an initial extrusion operation, following which it enters a cross head operation where a pair of outer lobes are attached to cross sectional exterior surface locations according to a second stage extrusion operation so as to be integrally formed therewith. Other steps include cooling of the dual stage extruded pipe, as well as sectioning and stacking the pipe. Additional steps include forming elongated slots or apertures into the central sleeve portion of the finished extrusion, such in non-interfering fashion with the individual passageway defining and lobes.

摘要： A method of harnessing geothermal energy to produce electricity without polluting the environment by using universal portable closed loop systems is provided. The Scientific Geothermal Technology, The Self Contained In-Ground Geothermal Generator; The Self Contained Heat Exchanger; and The IN-LINE PUMP consist of several designs and variations complementing each other and/or operating separately in many different applications in energy sectors. The system can be used for harnessing heat from established lava (tube) flows; harnessing the waste heat from the flame on top of flare stacks; and other situation where a source of heat is difficult to access or is not suitable for relatively heavy equipment of a power plant or power unit. Also, included is an exemplary use for restoration of the Salton Sea which implements the Scientific Geothermal Technology for exchanging water from a salty terminal lake with oceanic water and for production of electricity and fresh water.

摘要： A tank for waste water partially or fully buried in the ground or immersed in water includes a wall made of a high thermal conductivity material, which in turn has a pair of walls forming a cavity creating a circuit of a convective fluid for heat exchange with both the waste water contained inside the tank and with the ground and/or groundwater external to the tank.
