Engineers At Lockheed Martin Create Perforene: More Efficiently Converts Saltwater To Clean Freshwater.

John Stetson - Lockheed MartinLockheed Martin has announced that they’ve created an atom-thin carbon membrane that will significantly reduce the cost and energy required to convert saltwater to freshwater. It’s called perforene and its one-nanometer sized holes are large enough to let water flow through but small enough to filter out salt from seawater. From Lockheed Martin engineer John Stetson:

“It’s [perforene] 500 times thinner than the best filter on the market today and a thousand times stronger. The energy that’s required and the pressure that’s required to filter salt is approximately 100 times less [than reverse osmosis].”

Perforene, if it reaches the market, would be a great solution for coastal areas that have limited access to freshwater and that may not be able to afford building and operating an expensive desalinization plant. The downside: mo water mo people. [Reuters]
