Another Simple Idea

Last week I posted about an interesting design idea in which someone built a greeenhouse around a house. Jim commented on that post with another great idea. This gentleman in Nebraska (very close to me) has a greenhouse in the ground that also uses geothermal heating to grow oranges and lemons all year around.

This is a great idea. I've always wondered why more homes are not built partially into the ground to capture the ground's temperature stability. Watch it here.

Do you have another great idea that we should highlight?
