How a Saltwater Battery Desalinates Seawater and Captures Carbon.

Drop your phone in the ocean and you'll quickly learn that seawater destroys batteries. So a seawater battery that actually runs on seawater sounds backwards. Yet researchers in Korea have spent more than a decade developing one. This single system stores energy, turns seawater into drinking water, and captures carbon dioxide from the air.

One device doing the work of a battery, a desalination plant, and a carbon capture system. Is this the Swiss Army knife solution to our energy and freshwater challenges, or is a 3-in-1 promise simply too good to be true?
