Nanoporous graphene can strain salt molecules from water

Thirsty? No? You will be. It's just a matter of time. It's also just a matter of time until the expansion of humanity makes fresh water a more precious commodity than a new iPhone, butgraphene sheets with lots of little holes in them could soon solve the problem by making fresh water from salt water with incredible efficiency.

Salt water is salt water because it has salt in it. That is to say, amongst all of those little molecules of H2O (water), you'll also find slightly larger molecules of NaCL (salt). The salt molecules cause lots of problems, not the least of which is that they render the water undrinkable by anyone except fish.
