Cargo ship runs on wind power

SkySails' first cargo ship, with a huge computer-controlled kite, was recently flagged off by Eva Luise Koehler, wife of German President Horst Koehler.

The ship MV Beluga SkySails started its maiden voyage from the city of Bremerhaven, Germany to South & North America (and back) and the SkySails-System with its 1,722 square-foot towing kite has been put into operation successfully. This new technology can tow cargo vessels and superyachts, reducing fuel consumption by 10 to 35 per cent on annual average. SkySails used Maple symbolic mathematical software for engineers to develop its simulation devices. SkySails GmbH & Co. KG, based in Hamburg, Germany, develops, produces, and distributes towing kite wind propulsion systems for modern means of sea travel and transportation. These systems make the operation of ships more profitable, safe, environment friendly, and independent of scarce oil resources. The SkySails system consists of a large towing kite similar to a paraglider, which is navigated by a fully- automated control pod and is connected to the ship via a towing rope. The control pod performs similar tasks as a paraglider pilot - shortens or lengthens the control cords, thus changing the aerodynamic profile of the towing kite - and governs its flight path.
