Graphene nanotechnology makes Desalination 100 times More Efficient


“New materials such as Perforene will make it possible to cost effectively desalinate much needed water to quench ‘thirsty lands and peoples’ around the Globe. Combining a sustainable, renewable, cheap and abundant Energy Source(s) such as Solar or Hydrogen Fuel-Cells … is a MUST looking ahead into lifetimes of our children and grand children.” ~ Bruce W. Hoy, C.E.O. Genesis Nanotechnology, Inc.

Great Things from Small Things .. Nanotechnology Innovation

Graphene Desal shutterstock_233104066-660x487Engineers at Lockheed-Martin recently developed and patented a molecular filtration membrane called Perforene which can desalinate seawater using only 1/100th the energy of the best existing desalination systems.

Perforene is made from graphene, the exciting new nanomaterial which comes in the form of one-atom thick sheets of carbon atoms. Like an overzealous nanotechnology, graphene seems to photobomb itself in as the solution to numerous environmental problems such as, storing electricity, removing air pollution, advanced photovoltaics, high strength materials and now desalinating water.

Under a microscope, this material looks like a mesh net with holes as small as one hundred nanometer. These holes are small enough to block the chlorine and sodium ions in salt water but large enough to allow pure water molecules to pass through.

The material was invented by Lockheed engineer. In an interview with Reuters, Stetson said that this new material is 1000 times stronger…
