Solar desalination system eliminates toxic brine while producing fresh water
A good honest bake. Not flashy, but you'll finish the whole bagel.
Summary
Scientists have developed a solar-powered desalination system that converts seawater into fresh water without producing toxic brine, a major environmental problem with traditional desalination. The system uses laser-textured metal panels that harness sunlight to evaporate water while automatically moving salt deposits away from the working surface to prevent clogging. Tested successfully with water from three oceans, the process can recover nearly all salts as solids, and the leftover materials could potentially be used to extract valuable lithium for batteries. This addresses the global need for affordable, sustainable drinking water for the 2.2 billion people lacking safe water access.
Key quotes
· 3 pulledAccording to the United Nations, 2.2 billion people still do not have access to safely managed drinking water.
Traditional desalination methods such as reverse osmosis and thermal distillation can be expensive and energy intensive.
When discharged back into the ocean, brine can damage marine ecosystems.
