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.

MIT engineers and collaborators developed a solar-powered device that avoids salt-clogging issues of other designs.

      It will certainly comes with a preposterous amount of salt to deal with. That’s a critical limiting factor with desalination.

        I thought the salt level in the input rises. So you could cycle the input with fresh salt water and pump the higher salt content stuff back to sea.
