Solar-Powered Desalination Produces Drinking Water and Recovers Valuable Minerals
📰 Original title: New Desalination System Turns Seawater Into Drinking Water and Useful Salts

Researchers at the University of Rochester, led by Professor Chunlei Guo, have developed an innovative solar-powered desalination system that converts seawater into drinking water while recovering nearly all salts in solid form. Unlike traditional desalination methods that create environmentally harmful brine, this system uses black metal panels etched with femtosecond lasers. The laser-textured surfaces make the panels highly absorbent of sunlight and extremely effective at wicking water. Water is pulled across the panel, evaporates, and leaves the salts to slide into untreated regions, preventing clogging and maintaining continuous operation. This technology not only produces fresh water but also isolates valuable minerals, including lithium, which is essential for lithium-ion batteries. In tests using water from three oceans and the Great Salt Lake, the system extracted almost all salts and recovered about 50% of lithium from the residual minerals. The panels’ design allows for scalable applications, offering potential global benefits for drinking water access and sustainable mineral sourcing. Funding came from the National Science Foundation, the Bill & Melinda Gates Foundation, and the Worldwide Universities Network. While the technology is still in the proof-of-concept stage, its innovative approach could reduce energy consumption and environmental impact compared to conventional desalination.

💁🏻♀️ TIL: Kelsey Pfendler, 31, left #Monterey, #California on May 21, in an attempt to become the youngest woman to row solo and unassisted to #Hawaii. 🚣
⛈️ In her first week, she’s already faced storms, lost her freshwater supply, and is relying on tortillas and peanut butter until the #sun returns to power her solar desalinator. The current solo record is 86 days.

💧 New solar-powered system produces fresh drinking water from seawater without chemical additives.
☀️ The technology uses black metal etched with lasers to absorb sunlight efficiently and a self-cleaning surface that separates salts.
💎 Leftover salts are transformed into useful materials, including lithium for rechargeable batteries, addressing both water shortages and mineral demand.
