Patent ID: 8616000

Claim:
A heat extraction system for generating geothermal heat from within a well, comprising: a heat nest configured in an area between a heat point determined as a lowest depth where appropriate heat is encountered in a well and the bottom of a bore hole of the well; multiple bore holes being drilled into rock surrounding the heat nest configured to create more surface area through which geothermal energy may flow, the multiple bore holes being drilled in multiple directions, including drilled vertically, horizontally, diagonally or any angle, in relation to the bore hole of the well and being filled with heat conductive material; a heat exchanging element configured with a first side and a second side, and configured in the heat nest at a point between the heat point of the well and the bottom of the bore hole of the well; a piping system configured with a downwardly flowing pipe coupled to the first side of the heat exchanging element for bringing contents from a surface of the well into the heat nest and configured with an upwardly flowing pipe coupled to the second side of the heat exchanging element for carrying heated contents to the surface of the well from the heat nest; and a heat conductive material injected into an area within the heat nest near the bottom of the well between the heat exchanging element and rock surrounding the heat nest to form a closed-loop, solid state heat exchange system to heat contents of the piping system flowing into and out of the heat exchanging element at an equilibrium temperature at which the rock surrounding the heat nest and generating the geothermal heat continually recoups the geothermal heat it is conducting to the heat conductive material and above which the geothermal heat generated by the rock surrounding the heat nest dissipates as the heat conductive material conducts heat from the rock surrounding the heat nest to the heat exchanging element, the heat conductive material connecting the rock surrounding the heat nest and the heat exchanging element, the heat conductive material solidifying to substantially fill the area within the heat nest to transfer heat from the rock surrounding the heat nest and the heat exchanging element; the closed-loop, solid state heat extraction system extracting geothermal heat from the well without exposing the rock surrounding the heat nest to a liquid flow.
