Wind to purify salt water

It's always great when we get to feature newinventions that could change the world for the better. Take thiswindmill for example. It's capable of turning salt water into pure,clean drinking water.

"The windmill was designed at the Delft University of Technology (TUDelft) in The Netherlands," explains. "It runs by usingthe wind's mechanical force to pump water, and utilizes a high techreverse osmosis membrane. The pumped water is pushed against thismembrane at approximately 60 bar of pressure, and the salt is keptinside while pure water travels across the membrane.

"The windmill setup is estimated to 5 to 10 m3 of fresh water a day, based on the device's capacity at varying wind speeds."

This could be world changing. If these wind-driven machines wereinstalled in nations in which people are being forced to drinkcontaminated drinking water, millions of diseases and deaths could beprevented.
