I live about 40 miles from the edge of the caldera. I've wondered about drilling down to get heat. Nobody else has done it though, with the exception of the various hot springs around here. There is a hot-ish spring on our property, in that it stays snow free through the winter. That said, if there was a bunch of heat near the surface presumably our well water would be hot. It isn't.
