Membranes of graphene oxide permit water vapor to pass through them, while showing itself to be impermeable to any other gases and liquids. Tests carried out at room temperature have resulted in the further distillation of alcohol, without the heat and vacuum normally used with traditional methods. This process could revolutionize biofuel production by slashing production costs and increasing production efficiency.

In a similar process, research into graphene based filters has also resulted in the massive out performance of any other techniques when it comes to the desalination of water. The world’s water concerns could be a thing of the past within a decade.
