This concept makes a lot of sense to us. As Skyrobotic says, "How can you make affordable housing and then saddle the owner with atrocious energy bills." I am paraphrasing a bit but that is the concept. This is a neat proof-of-concept for a zero energy house.
Well, who reads this stuff? Probably a handful if any but it sure is fun to write these random, or maybe not so random, thoughts and ideas. Maybe a thousand years from now if anyone is still alive they will dredge up these electrons and see what life was like back in the early 2,000s and late 1900's.
