Well, this may well be the coolest video you see today. It’s a TEDx talk from a fellow named Behrokh Khoshnevis, who is a professor of engineering at USC, where he directs something called the Center for Rapid Automated Fabrication Technologies. CRAFT has stated as its grand challenge “building a custom-designed house in a day while drastically reducing the costs, injuries, waste and environmental impact associated with traditional construction techniques.” The applications of such rapid-fire housing are endless: affordable housing for the poor; “extraterrestrial buildings constructed from in situ materials”; emergency FEMA-style housing, and the like.
