Researchers at the University of Rochester have developed a zero-waste solar desalination system that converts seawater into fresh drinking water while simultaneously recovering lithium from the brine. The system uses femtosecond laser ablation to create a superwicking surface that draws salt to the edges of a panel via capillary action, preventing scale buildup that normally kills desalination devices. The study, published May 30 in the journal Light: Science and Applications, could help address both global water scarcity and the growing demand for battery-grade lithium.
