Ah. I see some one mentioned the geo-thermal power system.
They're using that in.. Iceland (I think?) and New Zealnd.
people are learning alot about how to do the tech well.
Like, one of the problems is keeping the water IN the system. It's actually hard to cross connect the two 'bore' holes. SO when you pump water down one... Not all the 'water' comes back up.
I think the folks in Iceland have a good-er-er way of resolving this issue.... don't have any links atm.
I've heard.. possibly in New Zealand? That one of the other down-sides is kind of making a 'Mud volcano'.
Basically you allow higher temperature material to rise up closer to the surface. It mixes with ground water and spoul and 'BLURT" steaming hot mud errupts out of the round.
So.. it's kind of a viable way to parasitically suck the heat out of the planet.... but there are still tech hurdles to over come.
Plus... you can only really do it in places where the crust is kind'a 'THin' or 'Faulty' to begin with.
The idea would be rather a non-starter in a place like Australia. The continent sits pretty much smack in the middle of its 'Plate'.
Cheers!
Not at work.
the problem they are experiencing is where pockets of heat come closer to the surface. what the people in russia tried to do is drill a hole to the center of the earth (right in the middle of the continental plate) they found at 7.5 miles down they could no longer cool their drill bits because the water turn to vapor intantiousiouly.
on the simple explanation surface all one need do in drill a idk 12 inch hole 7.5 (let's say 12 inches is the butter zone of heat extrapolation to loss.. and rather than pump raw water down this pipe you plant a heat exchanger at the bottom and this will eliminate all of the problems you listed about boring two holes or pushing up mud. the idea is to keep everything self contained so there is no expenditure of water as a quasi fuel or media to transfer heat. and this will further allow the use of purposely designed coolants that can hold more heat and lubricate internal machine parts seals and pumps.
