Every few years, you hear about some new revolution in the process, but nothing much after. Why is that? Is it very hard to scale up or…?
Also, is it going to become more viable as fresh water is becoming more scarce?
Thank you in advance.
Thank you all. So it was basically what I thought. It’s not hard to do, but it is not really feasible due to many factors.

I wouldn’t say it is hard more than it’s energy intensive.
Even using the Sun’s heat–a solar still– which is free, takes quite a bit of energy: I guess it depends on scale as well.
To provide potable water for a medium sized city needs a lot of energy. Then, what to do with the salty sludge leftover.
Do you return this to the ocean? It will make the dump site toxic. Do you store all of it somewhere on land? Again, it’ll make that area toxic to plants and you don’t want rain bringing that salt to the water table, contaminating it.
