Desalination system could produce freshwater that is cheaper than tap water (news.mit.edu)

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.

The question with desalination is always the same what will you do with the salt ?

If it was just salt it wouldn’t be a problem. Salt is an essential nutrient and industrial product and we actually run seawater evaporators today specifically to farm the salt. We mine salt out of mountains and ship it around the world. Salt is our friend.

The actual question is what to do with the concentrated salty sludge by products.
