Desalination system could produce freshwater that is cheaper than tap water
news.mit.edu
A new solar desalination system takes in saltwater and heats it with natural sunlight. The system flushes out accumulated salt, so replacement parts aren’t needed often, meaning the system could potentially produce drinking water that is cheaper than tap water.

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.

        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.
