THOUGHT EXPERIMENT:
We cool the whole sheet – 5 km to – 6 km down to 100 C
These 9,63 x 10^6 km^3 x 1 J/(g*K) x (dT= 75 C ) x 3 g/cm^3
= approx. 2 x 10^24 Ws = 7 x 10^17 kWh-th = 700.000.000 TWh-th
For comparison: US yearly prime energy use about 25.000 TWh-th
Natural geothermal heat upstream 70 kW/km^2
mulitiplied with USA´s 9.629.091 km^2 ………………….. 0,674 Terawatts
x 8760 hours/year…………………………………………….. 5.904 TWh-th
So in this sheet is enough energy to supply the USA for 28.000 years.
Theoretically….
In reality the problem is the price for deep boreholes.
We know enough about steam turbines and engines.
In order to use this energy more effort is needed to improve
manufacturing of very deep holes.
One little step towards this goal might be my invention ELEVATOR BOREHEAD
