One Atom thick Graphene is future of Water Desalination

One Atom Thick Graphene -- How thick is it? Take out a piece of paper and draw a straight line on it with a pointed pencil. The line's thickness is Graphene.

With the availability of fresh water dwindling in many parts of the world, a problem that is expected to grow with populations; researrchers at MIT are looking at Seawater. The only promising source of potable water -- the world's virtually limitless supply of seawater. But so far desalination technology has been too expensive for widespread use.

Now, MIT researchers have come up with a new approach using a different kind of filtration material: sheets of graphene, a one-atom-thick form of the element carbon, which they say can be far more efficient and possibly less expensive than existing desalination systems.
