Minnesota-based Cargill has developed modern sails they’re calling ‘WindWings’ that allow giant cargo ships to harness wind energy.

Last week, the first ever vessel outfitted with the giant 123-foot sails embarked on a test journey from China to Brazil. It’s said the sails could help the ship dramatically slash its fuel costs and greenhouse gas emissions.

Andrew Freedman from Axios shared more about the innovation and what it’ll take to decarbonize the marine shipping industry.
