The new [nanotube-based]membranes, developed by researchers at Lawrence Livermore National Laboratory (LLNL), could reduce the cost of desalination by 75 percent, compared to reverse osmosis methods used today, the researchers say. The membranes, which sort molecules by size and with electrostatic forces, could also separate various gases, perhaps leading to economical ways to capture carbon dioxide emitted from power plants, to prevent it from entering the atmosphere.

Our planet faces a severe water shortage problem. There is the prospect of water wars in many places in the world. But there is a new technology using nanotubes that could reduce the cost of water desalination to one fourth of what it is now.
