Desalination

US engineers turn salty seawater into drinking water with new cheap method The device simplifies desalination by cutting chemical use, boosting sustainability, and saving 20 cents per cubic meter. The technology turns seawater into drinking water with fewer chemicals. Researchers have developed carbon cloth electrodes that efficiently remove boron from seawater, potentially replacing costly chemicals in desalination.

On top of all that, the U.S. president has been seen as [...]
