Very interesting technology. The applications for it, if the price is right, are endless. Emergency disaster relief, third world country development, TEOTWAWKI, homeless shelters, military bunkers (can it withstand a bullet impact and not be punctured?).

The biggest question I have is how do they dismember it? Is it so permanent that it requires a bulldozer to break it up, or concrete saws to break into more manageable pieces? As in, sure, bring in 100's in Katrina type situations, can pop them up in less than a day to provide emergency shelter to people. But what happens a few weeks to months to years later? Surely you wouldn't leave them standing indefinitely, right?
