How a Saltwater Battery Desalinates Seawater and Captures Carbon. Go to https://ground.news/undecided for an innovative way to stay fully informed on tech, energy, the climate and more. Save 40% on the Ground News unlimited access Vantage plan with my link. Drop your phone in the ocean and you learn fast that seawater destroys batteries. So a seawater battery that actually runs on the stuff sounds backwards. Yet researchers in Korea have spent over a decade building one. This single system stores energy, turns seawater into drinking water, and pulls carbon dioxide from the air. One device doing the work of a battery, a desalination plant, and a carbon capture rig. So is this a real Swiss Army knife for our energy and freshwater crises? Or is a 3-in-1 promise just too good to be worth its salt?
