According to MIT, this technology works even at small scale, with one the size of a suitcase able to desalinate 6 litres per hour, and only needing to be serviced every few years.

Here's a video detailing how it works.

You'd still need a water source, so it'd be most effective in arid climates by the ocean. And I don't know how quickly these clog, you'd need to do something with the tons of salts that you get out of the ocean water.

God, if only there was a use for sea salt

Are you implying what I think you are?

Human need for salt is quite limited and prety much already saturated. Increased salt concentration from salt water that has been reintroduced to the ocean by desalination plants has already fucked up ecosystems.
