Graphene is a two dimensional material consisting of a single layer of carbon atoms arranged in a honeycomb or chicken wire structure. It is the thinnest material known and according to mechanical engineering professor James Hone, of Columbia University, graphene is strongest material ever measured, some 200 times stronger than structural steel. Graphene conducts electricity as efficiently as copper and outperforms all other materials as a conductor of heat. Graphene is almost completely transparent, yet so dense that even the smallest atom helium cannot pass through it.
3D printing is rapidly approaching Diamond Age proportions. This won’t be within consumer-reach any time soon, but the implications for product design using graphene (also known as carbon nano-tubes) are promising. Also: space elevators.
