Your Smartphone, Made of Cement..

Scientists just discovered a way to turn masonry into metal. Using lasers.The process they discovered, published yesterday in Proceedings of the National Academy of Sciences, transforms liquid cement into a kind of glass-metal fusion that is exceptionally good at conducting heat and electricity. The resulting hybrid, the scientists say, can be used as a semiconductor in electronics: it offers good conductivity, low energy loss in magnetic fields, better resistance to corrosion than traditional metal, less brittleness than traditional glass, and fluidity for ease of processing and molding.
