Have any more improvements been made in the process of removing salt from ocean water in large volume? Is anyone actively still working on this?


Did a quick google search and found that Israel launched a large desalination plant back in 2015 (uses reverse osmosis). Here's the source: https://www.technologyreview.com/s/534996/megascale-desalina...


Thankyou. That would suggest it is feasible on a large scale. Hopefully more countries will start to invest in desalination plants. With ocean levels rising, now should be a good time to optimize that process even further.


Desal works fine, but uses a lot of energy. With ever cheaper solar panels, there will soon be a point where it makes sense to power a desal plant on just solar power.

But there is still the small matter of the salt that is left over. There is so much salt on this planet that no one wants it. You could dump it back in the ocean, but wherever you do so becomes too salty, which would be really bad if you dump it back right where you're doing your desalinization.

Which means we either need to ship it to the middle of the ocean (which maybe you can do with autonomous solar powered boats) or you need to figure out some other use for all that salt.


Perhaps that could augment or replace our existing salt mining.
