A high explosive charge listened two by three microphones in the ground. Gold is soluble in high pressure water. And he is the source of all gold deposits on earth! As the geothermal water has found its way out to the surface, and the gold precipitate it as the pressure drops. Thanks to the late professor Argent for this idea! But people always want a new stuff on the Internet! We can set up large polyurethane enclosures in the Australian gold fields. Isolating the air from the surrounding mad hot desert air. We use solar powered pumps, to drive a Carnot cycle. As the pressurise the air it gets hot. 255° C hot - from air at 80° C. If we increase the pressure pressure of the air by only 50 per cent, and it gets mad hot. We lose heat by a high radiator - throwing out t...
