concrete canvas :: the building in a bag

There's a lot of excitement over the recent conclusion of the Shelter in a Cart competition...The efforts to approach world problems with design have multiplied fantastically lately and so, in light of that, I also wanted to add the Concrete Canvas into the mix. It is not new, but it's neat and new to me...Taking inspiration from the compressive strength of an egg, the Concrete Canvas is a rapidly deployable hardened shelter that requires only water and air for construction. It can be deployed by a person without any training in under 40 minutes and is ready to use within 2 hours. plus, with a design life of over 10 years, (tents only survive for 2 years). more info, found here
