Two engineering students thought they could do better and invented Concrete Canvas, a fabric impregnated with concrete that can turn a tent into a hardy, permanent structure in 24 hours. Just add water. Fundamentally, Concrete Canvas is a clever means to erect a sturdy, permanent structure anywhere. Packed in a crate, the entire building comes ready to erect with a minimum of infrastructure or extra tools.
