WOW I have been through there several times and had no idea it was there! Gonna have to go on a field trip !

Another video here.



And another.

First heard about that greenhouse on NPR in the early '90s after moving to South Dakota.  Called Mr. Finch and went down to check it out as my partner and I were exploring a number of possible housing options.  It was amazing.  Colorful little birds and butterflies inside to aid pollination and even saw a tree frog at work on insect control. 

Hard to understand how we have not been able to make geothermal heating and cooling a larger part of energy solutions.   When I was there, his only ongoing expense was running a box fan to push the air through the tubes.

I agree.  If you have the resources this seems like a no-brainer.
