Why not just put water pools in plastic domes, collect the dew at night?

Creating electricity with a lot of effort and using it for heating water doesn't make sense.

State of the art desalination, reverse osmosis, doesn't heat the water it pushes it through semi-permeable membranes.

Cost. Large scale desalination is really cheap as in gallons per cent.
