Wind-Powered Cargo Ships
It’s been more than a century since large industrial ships relied on wind power to cross the seas. German manufacturer SkySails is hoping to convince more shipping companies to rediscover the power of wind. It’s towing kite propulsion systems for cargo vessels can reduce a ship’s annual fuel costs by as much as 35%, and, under optimal wind conditions, fuel consumption can be cut by up to 50%. If this sort of energy supplement could become standard, it could help a global economy be gentler on the planet.
