Beluga SkySails- Are the frist to apply SkySails towing kite propulsion system on a cargo vessel worldwide. Future kites will have a sail area of as much as 600 square metres and will help reduce fuel consumption by 20 to 30 percent. No extra crew needed on the fully automated final version which will launch and retact at a push of a button. There will also be a big red button for emergency cutaway. - http://www.beluga-group.com/
