Water Scarcity

A new desalination method produces drinking water from seawater without chemical additives, using a solar-powered system with a self-cleaning surface that separates and collects salts.

Scientists at the University of Rochester developed a solar desalination system that turns seawater into drinking water without creating environmentally damaging brine. The system uses laser-textured metal panels to evaporate water and automatically move salt deposits away from the working surface.
