Maybe deep in the mantle there are huuuge deposits of hydrogen and methane that we can use as fuel. Imagine a hydrogen economy driven by deep mantle drilling at depths of 300-400 km. Though I'm not sure that can be done at the temperatures and pressures down there; but then the material may be pretty solid there.

If we had the ability to drill down to 300-400 km, why wouldn't we just use geothermal power?

I suppose that since we don't have that ability, we haven't thought about that yet...
