Abstract :
Four kilometers down below the orange earth of Australia¿s Cooper Basin lies some of the hottest nonvolcanic rock in the world¿rock that the geothermal industry had never seriously considered using to make electricity. But next month Geodynamics, an eight-year-old company based in Milton, Queensland, will prove otherwise when it turns on its 1¿megawatt pilot plant here. The company has done more to harness this unconventional form of geothermal energy than anyone else in the world.
