Graphene is the thinnest and strongest material known to man. The pure carbon substance is 200 times stronger than steel, harder than diamond and thin enough that an ounce could cover twenty-eight football fields. It’s also transparent, more conductive than silicon, flexible like rubber and cheap to produce. It’s been touted as the “miracle material” for at least a decade. It could be used to build a space elevator. It’s already been turned into a 3D-printing material to produce printed electronics. It could also bring about flexible, highly-efficient solar panels, and the lightest, smallest, most efficient car batteries ever produced. For now, its properties have been successfully demonstrated by the UK National Graphene Institute in a market-ready light bulb. A good sign of more projects to come.
