Graphene. It can be stronger than steel and thinner than paper. It can generate electricity when struck by light. It can be used in thin, flexible supercapacitors that are up to 20 times more powerful than the ones we use right now and can be made in a DVD burner. It’s already got an impressive track record, but does it have any more tricks up its sleeve? Apparently, yes. According to researchers at MIT, graphene could also increase the efficicency of desalination by two or three orders of magnitude. Seriously, what can’t this stuff do?
