Neatorama picked up this wonderful story about Concrete Canvas, and I'm just thoroughly fascinated. Scientists have created a cloth that's lined with concrete. But here's the genius of it: the cloth doesn't function like concrete until you add water to it.
That means you essentially have a building in a bag. You can fold up a concrete cloth tent, carry it to wherever you'd like to set it up, and then water it to make a solid structure! It seems like Concrete Canvasses could be a perfect solution for creating quick housing relief in the advent of disasters, or shelters in wartime. And the potential applications haven't gone unnoticed; the creators have been winning all sorts of innovation awards recently, but you can read more about their invention here.
