Reply to comment by remek in UIUC Researchers propose a new way to get fresh water from seawater, without the disadvantages of traditional desalination. They say that a vertical “capture surface” that is 210 m wide and 100 m tall, could extract enough vapor floating above warm oceans to supply 500,000 people with freshwater by lughnasadh

Because the "shortage" is entirely down to agriculture and it is not cost competitive to grow crops at these prices. Its fairly easy to meet residential water demand.

I really doubt that. That is a giant structure, which will create a ton of engineering challenges(many that won't be foreseen).

We are talking about something approaching skyscraper height, with over double the width of a football field, and this structure is supposed to be sitting over ocean water.

As an engineer, the project sounds insane. That is a massive structure to stick over of the ocean, and ocean water is highly corrosive so its going to take a ton of maintenance.
