Wind power
Freighters with sails — or, in this case, one very large sail that flies like a kite:
A kite the size of a football field will provide most of the power for a German heavy freight ship set to launch in December.
The Beluga shipping company that owns the 460-foot Beluga said it expects the kites to decrease fuel consumption by up to 50% in optimal cases as well as a cutback of the emission of greenhouse gases on sea by 10 to 20%. Interestingly, the ship will be hauling windmills from Esbjerg, Denmark to Houston, Texas.
The company that makes the kite for the German transport, SkySails, has made kites for large yachts but is targeting commercial ships with new, larger kites. And it has the ambitious goal of equipping 1,500 ships with kites by 2015.
The SkySails system consists of a towing kite with rope, a launch and recovery system and a control system for the whole operation. The control system acts like the autopitot systems on an aircraft, the company says. Autopilot software sends and receives data about the sail etc to make sure the sail is set at its optimal position.
