The University of Rochester's Institute of Optics has developed a desalination technology that can provide drinking water for 2.2 billion people without energy consumption. Employing femtosecond laser-textured solar panels, this method evaporates water without generating harmful brine, which typically damages biodiversity.
It can also recover lithium from saline water, with tests indicating around 50% extraction from samples of the Great Salt Lake. This process uses principles of evaporation and salt transport to avoid system blockage while promoting sustainable lithium production. The environmental advantages may lead to economic opportunities, reducing reliance on terrestrial lithium extraction.
