Geothermal synergy

Here's steam for thought on geothermal energy...Suck on that John Howard!
Rather than building multiple enhanced geothermal wells to pump water down into hot rock and extract steam to drive power-generating turbines at each site, the heat canal would draw from a much larger underground field for a much longer period of time — possibly measured in centuries rather than decades for the typical geothermal site. The heat canal, a horizontal bore 50 ft. wide and 80 to 100 miles long, 20,000 ft. below the surface and filled with sea water under pressure, with bore holes extending laterally 7500 ft. into hot rock, would generate an estimated 16 times the energy of the largest conventionally designed enhanced geothermal well, yet all that energy would be extracted from a single site. This design, Prof. Tester said, would significantly increase operating efficiency through a “synergy of systems.”
