Conventional geothermal energy systems utilize natural reservoirs of heat energy located below the earth’s surface.  Today, the United States Patent Office issued a patent which stores solar energy in subsurface geologic reservoirs.  The method includes transferring concentrated solar thermal energy to a fluid, thereby generating a supercritical fluid.  Once charged with the supercritical fluid, the subsurface geologic formation forms a synthetic geothermal reservoir.
