A geothermal well is provided including a first tube including at least one opening in a first depth; a second tube having a closed bottom in a second depth; and a third tube having a closed bottom in a third depth. The first tube is inside the second tube, which is inside the third tube, wherein the first tube has at least one opening in fluid communication with a first interspace between the first tube and the second tube; wherein the third depth and the first depth are smaller than the second depth. Through-holes are formed in the second tube above the bottom of the third tube, which allow fluid communication between the first interspace and a second interspace between the second tube and the third tube. A first sealing element and a heat insulating material are disposed in the first interspace above the through-holes.

An air handling system that includes at least one earth-coupled heat exchanger assembly that further includes a first pipe section having an inner diameter and an outer diameter; a second pipe section concentrically surrounding a portion of the first pipe section, wherein the second pipe section includes an inner diameter and an outer diameter, wherein the outer diameter of the first pipe section and the inner diameter of the second pipe section define a space therebetween, and wherein the space between the first pipe section and the second pipe section is evacuated to form an insulating vacuum therein; and a third pipe section concentrically surrounding a portion of the second pipe section, wherein the third pipe section includes an inner diameter and an outer diameter, and wherein the outer diameter of the second pipe and the inner diameter of the third pipe section define a passageway therebetween.

Boreholes used for generating geothermal energy or other purposes are formed at least in part by accelerating projectiles toward geologic material. Interaction between a projectile and the geologic material may generate debris or other material. The temperature of this generated material may be used to determine the potential for generation of geothermal energy using the borehole. Based on the temperature of the material, a fluid having a different temperature than that of the material is provided into the borehole for generation of power using geothermal energy.

Closed-loop geothermal systems operate by extracting heat from the reservoir and transporting it to the surface. To maintain high enough temperatures at the surface it is necessary to have significantly higher relative reservoir temperatures. While the thermal energy of the sub surface is abundant, reservoir rock is a natural insulator with a thermal conductivity of less than 20 BTU*in2/ft*hr*F. This low thermal conductivity prevents rapid regeneration of the reservoir temperature around the wellbore reducing the relative temperature below what is needed for electrical production. The Thermal Soak method uses time and multiple closed-loop wells to overcome the low thermal conductivity allowing for continuous production of heated fluid at surface.
