... http://www.windvinder.com/index.php?id=14&L=1 Now that is one crazy boat with one crazy mission. Rather like trying to find the end of a rainbow. And being an unmanned vessel which cannot change its course other than to maintain its "dead into the wind" heading, doesn't it pose a hazard to other vessels it might come across? -- KLC Lewis www.cafepress.com/tmen www.KLCLewisStudios.com |

... http://www.windvinder.com/index.php?id=14&L=1 Nobody's seen it because it doesn't exist. It is a pipe dream. Notice on the site there are no photographs of it in action. Just drawings. It can't work. You cannot harness enough wind power with a windmill on a boat to make the entire untethered vessel proceed directly upwind. It isn't going to happen because it defies the laws of physics. Wilbur Hubbard |

Probably was the reason it was posted here in the first place. Wilbur Hubbard |

I see they are taking donations I gotta admit, it's more imaginative than, "Greetings my friend, I am Oboe Ndugu, former Nigerian government official..." |

This is so refreshing. This is a more enlightened group that those fools over in Great Britain on uk.rec.sailing. Most all those idiots over there believe in this propeller contraption pie-in-the-sky sailing directly upwind crap. Wilbur Hubbard |

Wilbur Hubbard The usual windmills around here put out 2000 hp. Casady The reason a windmill can put out that kind of horsepower is because they are firmly attached to the ground. In other words they cannot be blown backwards by the wind. The ground and tower pushes back against the wind thus providing a vector's worth of power to the system. Put one on a catamaran and it will be blown backwards until it experiences little or no apparent wind. If it were 100% efficient the best it could do is stay in place against the wind. We all know there is no 100% efficient machine. That would be a perpetual motion machine which the laws of physics say cannot be. Wilbur Hubbard |
