The closer you get to the mantle the higher the temperature. This is why natural gas deposits are found deep but seldom oil. Oil is broken down to its most simple molecular components under heat and pressure ending up as natural gas.
one you get deep enough you finally have a new source of energy all together, geothermal. In the light of this, if you can actually drill that deep, I would imagine this energy would be relatively cheap, and is really limitless as long as the earths core doesn't stop producing heat (in reality, thats 4 billion years worth of energy)
I believe this would make hydrogen fuels possible, due to the amount of extremely cheap energy.
Strangely enough, I was involved with one of these projects about 20 years ago. The college I was attached to was drilling into what we called at the time ' The biggest Nuclear Reactor in the World'.
It was a big granite mass in Cornwall (UK) that was about 10 miles on a side, and so full of naturally-reacting fissile Uranium that the temperature deep underground was enough to turn deep-injected water into super-heated steam 'instantly'.
We had one of the biggest (non-govt) computers in Europe to do the modelling and two bore-holes in the ground, down one we pumped water, out of the other got steam at high pressure.
There was - I won't beat about the bush here - enough theoretical energy down there to supply a large part of the UK's annual consumption for, basically, for-ever.
It was certainly the best geothermal site in Europe and possibly the best in the world.
Unfortunately there were problems.
We were basically learning as we went along and although we had figured out that the best way to facilitate water > steam flow between the two holes was to detonate explosives deep underground, we hadn't figured out which ways the rock would fracture. It DID fracture all right - but mainly outward from the holes. So you were pumping water down that wouldn't come up again. And of course all that high-pressure steam started to make the leakage fractures worse.
And also we were working at greater depths and pressures than anyone else had done in that type of rock so the learning curve just got worse and worse.
At the end, the project failed, not through lack of funding, time, or enthusiasm but simply because the geology, and the engineering, were beyond us.
JPL
thats just it. the new technology for projects like this will most certainly be laser. In any event, It should be tried again every 10 years (if of course, I had a say in it)
Anyway. I think Laser techniques would overcome this. Partially because our geological understanding is better, and partially because a laser will eventually just "melt" through the surface. Simply, a matter of time.
opens up a world of possibilities.
