Sail the high seas, in 2008

Wow, via Auto Blog green I found this video of something I have heard of for the past few months. To save fuel on big ships, simply attach a sail! Of course it is not so simple, but this looks like a working prototype of one of the leading ideas. Basicly, you throw a big kite a few hundred feet up into the air and it pulls you forward, even if the angle of the wind is quite off. It also has the benefit of stabilizing the craft. It is supposed to provide 30% of the ships power when in operation. Talk about a heavy duty hybrid!
