Graphene water filters

This seems like it may be important. A graphene-based water filter that's two orders of magnitude more efficient than existing filters, good enough to replace desalination plants. And it looks like graphene is going to become relatively cheap in the near future. I wonder what kind of impact this will have on agriculture? IIRC Israeli agriculture relies on desalination plants to irrigate their crops; what happens desalination gets cheap enough for Arab and African nations to afford it too? Seems like it could change some lives.

The development could spare underdeveloped countries from having to build exotic, expensive pumping stations needed in plants that use a desalination process called reverse osmosis. "It's 500 times thinner than the best filter on the market today and a thousand times stronger," said John Stetson, the engineer who has been working on the idea. "The energy that's required and the pressure that's required to filter salt is approximately 100 times less."
