Cargo ship wind power

SkySails is a Hamburg, Germany-based company that is focused on reclaiming wind power for cargo vessels. The system works like "two giant kites that act as sails" connected through a towing rope rather than a mast. Now in testing mode, SkySails claims that the system can lower annual fuel costs "between 10-35% depending on the wind conditions, and up to 50% under optimal wind conditions." That equates to a saving of one third of a ship’s diesel costs.
