So what happened?

Sorry, I didn't realized that you've come up with perfect insulators and frictionless bearings.

Dummy... K-factor accounts for heat loss!!! is a calculation for all heat loss in relation to the heat being produced by the hole, and being extracted from the hoe to turn the generators.. if the BTU of the hole is over 4,000,000 and the delta/heat loss is under 4,000,000  say the steam process takes out 2,000,000 btu then we can run full capacity, however if the out put drops to under 2,000,000 btus then all we need do is back off on the cold water entering the hole till the heat can be replenished...

Or do you still not understand what makes the heat is this massive fission reactor at the earth's core? in essence that hole at that depth will always be at that temp. need hotter go deeper!
