This would seem to me to be the ultimate in reliable, clean energy. Estimates have potential output in the US at 100GWe in the US alone by 2050. Individual sites may cool down, but the Earth itself isn’t going to be cooling for a VERY long time! So there will always be a source of heat for this power-for the foreseeable future.
So why aren’t we hearing more about this? Why does it seem to be pushed aside, other than because the oil companies want it to?
