We have made steady progress on desalination over the decades, though mostly by working with obvious methods. Here we see a solar dome capturing from hundreds of mirrors. The energy dumped into the sea water produces steam which can then be condensed easily enough.
Not wonderful but it also works.
I would like to see someone attempt to exploit diurnal solar absorption that produces a surface layer of fresh water that can be drawn off. It could even be tidal driven.
How to Turn Sea Water Into Fresh Water Without Pollution

“The Line” is Saudi Arabia’s bold vision for the future of civilization: an ultra-modern city designed to house 1 million people and be entirely pollution-free.
But there’s one problem – it’s in the middle of the desert. And cities require a lot of water. Enter the Solar Dome, a new desalination system built on existing technology. It’s supposed to be a low-cost, efficient, and carbon-neutral way of turning saltwater into fresh water. With water scarcity already threatening the Middle East, Saudi Arabia is the world leader in desalination, but the process does pose problems. We take a closer look at the environmental costs of desalination, and how new innovation like the Solar Dome is trying to tackle these issues. Thank you for watching, liking, and sharing!
