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.

    There isn’t much that gets through in reverse osmosis. It’s very soft water.

    Lithium extraction is exciting, though. There’s some projects out there that suggest the process would be profitable on the non-lithium minerals alone, and then you get clean drinking water on top of it.
