Desalination system could produce freshwater that is cheaper than tap water

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.

    If you can get it dry enough, there are huge underground salt mines that could be back filled.

    But an larger ocean usually has enough currents that it dillutes out well enough to not be a major issue.
