Directory:Water > Directory:Desalination > A fresh way to take the salt out of water - Saltworks uses solar energy or waste heat to concentrate sea water. They then use the ionic gradient between the concentrated brine and two sea-water streams to pull ions from from a 3rd sea-water stream, apparently trading the reduced entropy of the desalinated water against the increased entropy of 'mixing' the brine and the other sea-water streams.
