The energy-efficient desalination system produces fresh water without chemical additives and transforms leftover salts into useful materials
Desalination is the process of generating freshwater from brackish or saltwater, usually through the process of reverse osmosis. While this can be a very useful tool in water shortages, it also has some pretty huge drawbacks--reverse osmosis requires a lot of energy, requires chemical treatment of the water, and produces concentrated brine as a waste product which can be harmful to aquatic ecosystems.
Researchers have recently discovered a new way to perform desalination using solar energy, which doesn't require chemical inputs and collects waste salt instead of producing brine. Concentrating the waste salt in a solid form instead of brine means that it can later be processed to extract valuable minerals like lithium.
