It is rather frustrating that there are all these resources and energy down there. All we have to do is dig a hole. It doesn't even have to be all that deep, a couple of hundred kilometres should do it. That's only as far as London to Birmingham (ish)
I mean, how hard can it be?
Very hard. The deepest BH is around 7.6 miles deep and took 20 years or so to drill. Plus, the rock gets very hot at that depth, hard to drill & keep the hole open. For geothermal energy, it wouldn't have to be so deep.
