Concrete Canvas

http://www.concretecanvas.com/

A fabric/twine 1/4" matrix is printed in rolls and sewn to arbitrary shape. It is coated on one side with PVC (or bioplastic) and then impregnated with a concrete mixture to create thin flexible fabric panels that harden into solid concrete after wetting. Inflation makes for quick prefab buildings. I feel a derivative of such a flexible technology (sans inflation) could be a good pairing for CEB and strawboard for creating roofs and other structural components ... A similar thing could be done with agriculturally derived resins instead of concrete. Something to think about for the long term.
