Amazing Tech

Okay I love simple ideas that can benefit tons of people. The only thing that I love more is simple beneficial tech with hilarious alternate uses. Enter Grancrete. I picked up this pop sci link off digg, and I'm blown away. A liquid concrete that can be sprayed on cheap lightweight frames, and it hardens in 20 minutes. Aside from being able to house millions of homeless people in developing countries without adequate shelter, imagine the ability to erect complete concrete walls in a matter of an hour using a frame of styrofoam and some spray on concrete. The nefarious posibilities are endless. Hell, imagine how dorm pranks could be revolutionized by this substance.
