Default DIY Solar Powered Ground Source Heat Pump!!!

I just ran into a very interesting project on Build It Solar.

We have a guy who has combined Ground Source Heat Pump with PV Solar to supply the total heating needs of his house!!!

Essentially free heating is claimed.

Here is a detailed, illustrated PDF that explains the whole thing.

Great job!
