It would seem like a natural in any country with a lot of waste ground, lots of sun, and access to the sea. It would require a water to water heat exchange system so that the more briny solution that has been giving off evaporation in the heat could be freshened with less briny solution from the sea. It could run off photovoltaics and windmills (not necessarily wind-generated electricity), but fairly low-maintenance, be very low cost, and the condensation process could take place up a hill in a buried tank (actually a series of them) with no vent. It would be extravagant in size for the amount of freshwater made, but cheap as all get-out.

Oh... good ideas.

definitely not for the desert islands unless they have a compact way of doing it.

well water is still cheaper than desalinized water by a long shot.

However, in the next decade or less— likely the
cost of desalinized water will drop below well water.

But I don’t think that’s generally known.

There’s right now a growing fund of money world wide going into desalination research—as cheap desalinized water will be one of the keystone technologies of the 21st century.
