Wind-Powered Cargo Ship Sets Sail : NPR

January 22, 2008

Welcome to the "green" age of commercial shipping. A German-made cargo ship will soon set sail, literally. The ship will be carried over the water partly by wind power.

The sails are from a German company called SkySails, and they're really more like giant parachutes. Each sail is about the size of a football field.
