Manufacturer of weapons for the Pentagon to reduce the cost of 100 times desalination


21/03/2013

Military contractor who gained fame for his fighters and missiles, announced the development of a method to reduce energy consumption for desalination of sea water. This will significantly reduce the cost of producing clean water at a time when the lack of water threatens to become a global problem.

This process, as described engineers Lockheed Martin Corp, based on the carbon thin membrane, pore size which is one nanometer, which is sufficient to block the salts in sea water and passage of molecules of water. One nanometer is one-billionth of a meter.

Since the size of the layers of pure carbon known as graphite, is a width of only one atom - by pushing them through the sea water in order to purify the salt, much less energy is expended.

"This is 500 times thinner than the best filter on the market and is a thousand times stronger than," - said John Stetson working on this technology. "Pressure and energy costs required for filtration of water are reduced approximately 100-fold."

According to the UN, about 780 million people worldwide do not have access to clean drinking water.

A prototype of the invention will be made later this year.
