Don't want to inject fluids under pressure near earthquake zones:

BTW, President Bush installed a geothermal heat pump at his new ranch house in Crawford; however, the pipes are only 300 feet deep, not anywhere near the depth proposed here, and use naturally occurring constant temperature groundwater for heat exchange.

The antifreeze liquid comes out of the ground at 59 F.

So that's how gwb is causing earthquakes........

Don't want to inject fluids under pressure near earthquake zones:

Actually, one of the long term proposals for protecting against damage from earthquakes, is to inject fluids into faults, lubricating them, and causing hundreds (or even thousands) of microquakes, to replace the small numbers of large destructive ones.
