What is actually happening is are sucking up river or sea water bye in excess a one metre. I would advocate using a little solar driven vacuum pump. Just one W of pumping is required to cause the seawater to rise and boil at one metre. Then a little energy is required to pump the water vapour to where needed. It is 1000 times easier to pump than liquid water. It is highly school physics! If we except one metre of vacuum even two ice, it is converted into pure water vapour. Obviously going him from water is far easier. But this idea can be used in the arctics, I avoiding the need to heat up ice. As the seawater freezes little reverts of running carry the salt away.
