New Solar Method Turns Ocean Into Drinking Water, While Extracting Valuable Lithium Without Waste

A new energy-efficient desalination system produces fresh water without chemical additives and transforms leftover salts into useful materials. Communities from California to the Middle East currently rely on desalination plants to convert ocean water to fresh water. But, common desalination techniques—such as reverse osmosis and thermal distillation—are energy-intensive, require chemical water treatment, and leave behind
