"Natural hot-rock exploitation"

Tends to fall off rapidly unless you happen to be right on top of a "hot spot".

Even drilling into the side of a magma chamber doesn't help much. New Zealand tried that.

Rock is a _very_ good insulator. When you tap off heat it takes a long time to "refill" and the more you take the longer you need to wait.
