Abstract

Apparatus includes a heat extraction system (SWEGS) in combination with some further apparatus for implementing some further functionality, e.g., associated with cooling/heating, remediation, mining, pasteurization and brewing applications. The SWEGS generates geothermal heat from within a drilled well, and includes a heat conductive material injected into an area within a heat nest near a bottom of a drilled well between a heat exchanging element and rock surrounding the heat nest to form a closed-loop solid state heat exchange to heat contents of a 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 that the rock 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 may be configured to solidify 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 piping system may be configured to bring the contents from a surface of the well into the heat nest and carry heated contents to the surface of the well from the heat nest. The closed-loop solid state heat exchange may be configured to extract geothermal heat from the well without exposing the rock surrounding the heat nest to a liquid flow, and provide heated contents to the piping system for further processing. The further apparatus receives the heated content and further processes the heated content in order to implement some further functionality based at least partly on using the heated content.
