Sun-Powered Desalination with Salt Harvest | Science News

Scientists have invented a solar-powered desalination system that turns ocean water into fresh water without dumping harmful brine back into the sea. Using laser-etched metal panels, it heats water to evaporate it while harnessing the coffee ring effect to isolate salt as a solid. This breakthrough eliminates the need for pre-treatment chemicals and could even extract valuable minerals like lithium from the recovered salt—turning waste into a resource. Still in early stages, the tech promises scalable, eco-friendly water production powered by the sun. Listen in comfort:Get a discount on a Soli Pillow: http://solipillow.com/discount/dnn.
