We've Come Full Circle - Freight Ships Now Using Sails Again

A German company has developed a new accessory for freighters, sails.

On the way out of the harbor, it lofted a kite-like sail that will be deployed any time the winds are right, cutting 10 or 20 percent or more off the fuel use for the trip, possibly saving as much as $1,500 a day in fuel costs, according to officials at Beluga Group, the owner of the vessel. Of course, this would also reduce carbon dioxide emissions.
