Lockheed has developed a special material that doesn’t need as much energy to drag water through the filter.
Graphene is a substance made of pure carbon. Carbon atoms are arranged in a regular hexagonal or honeycomb pattern in a one-atom thick sheet.
This special material is a film of a special structure of carbon, a honeycomb lattice called graphene. Because of its structure, the sheet is dotted with holes that are one nanometer or less. These holes between carbon atoms trap the salt and other impurities.
Graphene researchers won the Nobel Prize in Physics in 2010 for developing the wonder-material.
In addition, the film is super thin — just a single atom thick — so that the water simply “pops through the very, very small holes that we make in the graphene and leaves the salt behind,” John Stetson, the chief technologist at Lockheed for this initiative told Business Insider.

Good… Great news for developing countries and ocean going vessels. Hopefully it will lead to cheap, easy to use water filtration products for everyone to use. Can’t live without drinkable water.
