I was under the impression that there is molten core at the center of the earth? Not true? You don't have to dig far in some places to tap heat and heat is energy. Geothermal is already used in places where the heat is close to the surface and easily tapped. It's there everywhere if you dig deep enough and think it is just an engineering problem and if there is anything we do well it is overcome engineering problems. There are places in the US where it isn't far under the surface. Yellowstone for one. We routinely drill over a mile down now, I think we can get much farther down if we tried. The point is the energy is there, all we have to do is figure out how to get it instead of throwing up our hands and saying it's impossible as people like you want to do.
Nobody was suggesting it was impossible but there are huge technical challenges with widespread geothermal power. Suggesting it as an option without providing good explanation as to why and how is as sensible and productive as saying "if we had lots of solar power we could cheaply power the Earth". It's superficially true but working out the science and engineering of how to make it work is a different story entirely.
