A looped, pump assisted heat pipe system is provided including an underground well bore providing a vertical distance between an evaporator and a condenser of the system. The system includes a fluid loop with a circulating fluid, an evaporator arranged in the fluid loop configured to evaporate circulating fluid in a liquid state to a vapor and a condenser arranged in the fluid loop in the underground well bore configured to condense the vapor into the liquid state. A pump can be arranged at the base of the well bore, in the fluid loop between the condenser and the evaporator configured to pump circulating fluid in the liquid state to the evaporator. The system can be used in heating or cooling air for buildings and structures and water sources.

A system, composition and method for controlling fracture grown in the extraction of geothermal energy from an underground formation includes (i) introducing a first fracking fluid into an underground formation; (ii) introducing a second fracking fluid into the underground formation; wherein the specific gravity of the second fracking fluid is different from the specific gravity of the first fracturing fluid, thereby controlling the growth of at least one fracture in a downward direction, and wherein the fracking fluid in at least one of steps (i) or (ii) contains proppant particles having a thermal conductivity contrast of at least 5.
