Through a solar means of heating salt water and collecting the evaporated fresh water, this company is trying to make this historically high energy and massively destructive industry, sustainable. It takes 2 gallons of salt water to get 1 gallon of fresh water. So what happens to all the salty brine that’s left over? At great cost it typically is dumped back in the oceans and ends up destroying ecosystems. Some potential solutions with this approach include using the salt byproducts in the production of lithium batteries, grit for roads, fertiliser or detergents. See short video here showing the basic idea of how the desalination plant works.
