Frank Lloyd Wright and Big Holes

Frank Lloyd Wright's Unity Temple Goes Geothermal from Treehugger.

Looks like an impressive building.

I really like the sentiment behind this idea. It smells like another small step on the road to buildings being able to go 'off-grid' and be self-sufficient with regards to power. The stats say 'reduce reliance on fossil fuels by up to 80 percent'. This is a pretty nice number.

But how did they do it? A ground source system which takes air from under the ground (where it's hotter) to start the heating process. Fair enough. But necessary to support that system is 26 wells, each with a depth of 300 to 400 feet! That's a lot of bloody deep holes. Sounds pretty expensive and space-consuming, though I'd like to be wrong.

I still prefer solar.
