Football Field-Sized Kite Powers Latest Freighter 251
coondoggie writes to tell us that a new freighter set to launch in December will be receiving a hefty dose of power from a kite the size of a football field. The 460-foot ship, owned by the Beluga shipping company, hopes to see as much as a 50% drop in fuel consumption during optimal conditions. "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. The company also says it provides an optional weather routing system so that ships can sail into optimal wind conditions.The kites typically fly at about 1,000 feet above sea level, thereby tapping winds that can be almost 50% stronger than at the surface.

I think some of the article misses the point:
'What if fuel prices go down?' What if they don't? Prices will not go down in the long term and the companies using these will benefit the most.
'These can't be used in a head wind.' Well no sh*t Sherlock, thanks for that. It's to cut fuel use, not eliminate it. Any cut will be good for the company and the environment.

Seriously though... I can't think of any alternatives to fossil fuels that haven't run into enormous amount of flack.

Why do you suppose we shifted from sails to steam and then to internal combustion engines and then back to steam/nuclear in various Navies? It's because they are more efficient, reliable, controllable than wind powered propulsion. That's why even the most technologically advanced sailboats of today [doylesails.com] still have internal combustion engines for those countless times when sail just won't cut it.
All you utopians can flame me all you like. A dose of reality and old fashion time will show you that I am right. This is an investor scam doomed for failure.
