    en.wikipedia.org/wiki/Downhole_heat_exchanger

    A downhole heat exchanger, (DHE) also called a borehole heat exchanger, (BHE) is a heat exchanger installed inside a vertical or inclined borehole. [1] It is used to capture or dissipate heat to or from the ground. DHT's are used for geothermal heating, sometimes with the help of a geothermal heat pump.

  9. Gyrotron - Wikipedia

    en.wikipedia.org/wiki/Gyrotron

    In 2021 Quaise Energy announced the idea of using a gyrotron as a boring machine to drill a hole 20 kilometers in depth and use it to produce geothermal energy. [7] The technique would use frequencies of 30 to 300 GHz and would transfer energy to a rock 10 12 more efficiently than using a laser. Lasers would further be disrupted by the ...
