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.

      It depends where and how much. It would obviously need to be controlled, and spread out. You don’t want to dump a lot of it into slow moving water, that’s asking for problems. However, diluting it down, and dispersing it into stronger currents, over a large area should be fine (subject to proper environmental monitoring).
