Hybrid Solar House

Dave Pogue, at the NY Times, wrote about an interesting technology. A solar house that heats and cools itself by having an atmosphere.

It seems that it would work well in our region, with 300+ days of sunshine. They are basically kit houses, some assembly required. Unfortunately, they ship the house parts from NC and I am in CO. I think the freight charges will be significant.
I like the look of the Aquarius design with the optional garage (gotta have a garage in CO). My one concern is how sound travels from the basement through the double interior walls.

Maybe if we ever sell our current place and move…
