So they've re-invented a .

“When seawater is exposed to air, sunlight drives water to evaporate. Once water leaves the surface, salt remains. And the higher the salt concentration, the denser the liquid, and this heavier water wants to flow downward,” Zhang explains. “By mimicking this kilometer-wide phenomena in small box, we can take advantage of this feature to reject salt.”

With an improvement.

Great idea, but it will not go forward for two reasons. 'They' will not be able to sell water for $3.00 a gallon and it would crush the 'drought (fear) agenda'.

I haven't read the article yet but economies of scale should resolve the cost problem.

I prefer to use a old school pressure, some stainless steel tubing, and a sauce pot. Fit tube to cooker lid with a drill and food grade adhesive. Fill with salt water and boil. I like to use a camp fire it make it seem like I'm doing it to survive, if I pretend.
