Energy Efficient Graphene Desalination Membrane

Recent advances made in producing reverse osmosis membranes is interesting.  Any improvements that reduce the amount of energy required to force seawater through the membrane can only be a plus for all desalination plants, including ones that use wave energy.

"Graphene is only one atom thick but it is super-strong. A graphene membrane could be made thinner and more porous than a polymer membrane, so you would need less pressure — and therefore less energy — to push water through it."
