hobbit town u.s.a.

I just spoke to one of my fellow Energy committee member's of the Sierra Club. He works for a guy who not only builds really cool waste heat recovery systems that work off your air-conditioner, but also built his home such that the first floor is underground. He doesn't need an air-conditioner and doesn't have to worry about hurricanes or flooding. It sounds pretty cool (no pun intended) so I plan on visiting it soon. It was also on our local news this month. Looking forward to it.
