News: Orly Airport, in France is embarking on a program to extract geothermal energy from underground to slash it’s heating bills. Two shafts will be drilled on the airports perimeter to access a water table warmed by the earth’s core. The water from these deep shafts will be drawn up by natural pressure; the water will emerge at the surface at 75 degrees C (165 F). The water will then be injected into the airports heating system; once the heat has been extracted the water will then be pumped back underground.
