Sunlight Turns Ocean Water into Clean Drinking Water—No Toxic Waste!

Scientists just invented an amazing new machine that uses sunlight to turn salty ocean water into fresh drinking water, and it doesn't create any yucky toxic waste like other machines do! Special metal panels with a bumpy texture [roughened surface] use the sun's heat to pull water vapor up and away from the salt, kind of like magic. The best part? The leftover salt could even be used to make batteries for phones and electric cars!
