On paper this sounds like a really obvious great idea Have we ever built a working prototype/plant that does this?

- ChuckMcM 3y agoThere was a startup pursuing a test setup using an oil derrick of Santa Barbara if I recall. These guys[1] were proposing a different system (basically providing fresh water to an underwater habitat) however the paper goes over the basics pretty effectively.

- Baeocystin 3y agoIt does sound clever at first glance. It caught me at first, too. The problem is, your fresh water is now several hundred feet below the surface. To raise it up to where you are, you need pumps to push up the same exact pressure differential that you got by putting the membrane so deep. And if you need to do that anyway, just use surface level water and pumps for ease of maintenance and access.
