In a very limited area, where it happens to be both readily accessible and near population centers, which set of special conditions is exceedingly rare. Not really. Consider: Coso Geothermal, near Mammoth, Imperial Valley, Steamboat, Nevada.
Proximity to population centers is relative to how big of a plant you are building. Plus they can be tied into the grid.
But the "universal geothermal energy" proposed here is sheer crackpottery.
True. At best it is one of many alternative sources that will fill a limited need.
"Not really. Consider: Coso Geothermal, near Mammoth, Imperial Valley, Steamboat, Nevada." Yes, really. Compared to the widespread urban power needs for the United States there are damned few geothermal sites sited so they can be tied into the grid so as to get the power to them. (there "is" a limit to how far power can be transmitted, y'know).
