I'm currently entertaining the idea creating an off-grid solar-powered farm in the desert southwest. In the summer when the outside temp are 105 (F) / 40 (C) I'm wondering if a geo cooling option would work.

I recently saw a TV show where the used this to cool an off-grid home that was roughly 2500 sq ft.

From what I gathered, you send some air tubes down 8-12 feet below the ground where the air is a consistent 55 degrees or so. You pull warm air in from one part of the property, shoot it down the tubes, where it naturally cools down, and then back up and into the property at roughly 65-70 degrees.

The electricity draw involved is much lower the air conditioning, obviously, because you more or less are running small fans on the intake/outflow ends of the tube system.

Does anyone think this is do-able for a 700-900 sq foot mining shack out in the desert?
