What is that but a video taken from a boat that seems to be bobbing up and down with waves coming towards it. There is absolutely no evidence of the slightest bit of forward motion nor of any propelling device. The thing could be anchored for all one can see of it. If any of this were real there would exist hundreds of videos showing this craft and others moving directly upwind against a marked course (maybe fixed buoys) taken from directly above with plenty of wind vanes in plain view. There would be videos of an impartial certification team that thoroughly checking out the vessel for hidden propulsion methods such as batteries or other outside sources of power. But such videos do not exist and will not exist unless they are highly faked and unsubstantiated. Wilbur Hubbard I just checked YouTube, as well as a Google search of the entire internet, and there is not a single video of Wilbur Hubbard. |

The was an article in Popular Mechanics (maybe Popular Science) more than 30
years ago, I think, about a home brew inventor in Australia (maybe New Zealand) who had developed a wind powered boat that did just this. IIRC he had started with a keel boat that had been split down the middle and a section added to give greater beam. He could vary the pitch of the windmill blades according to conditions, and the power from it went to a large slow turning and efficient propeller. He could power dead upwind, and boat speed was about the same regardless of wind direction. Future plans were to mount the system on a catamaran with the prop located between the hulls about where the bow waves converged. "Wilbur Hubbard" wrote in message anews.com...

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.

They screwed up with that windmill stuff, and directly into the wind. Should have said it was always tacking upwind, with a simple auto tiller mechanism switching between port and starboard tack every so often as it wound itself up. Maybe add something about a wind harp aboard, always being strummed and emitting melodious or martial tones as the winds changed. "Have you seen it?" "Have you heard it?" Add a sound file to the web site so folks can hear what it sounds like. Charge for a full length version, gull squawks included. Dummy up a reasonable drawing or photoshop a pic. No sense lying small-time, right? --Vic |

http://www.windvinder.com/index.php?id=14&L=1 This looks like a rather large poetic version, perhaps less efficient, than the first prototype upwind model: this is a shaft with a small water prop on one end, and an air prop - a windmill really - on the other end. The shaft is held up at an angle by one or several floats to carry the shaft. Though it's hard to believe, this kind of water/windmill really does propel itself upwind always. Brian W |

At least they covered that in the link. 45 languages on a plaque telling whoever found it aground to send it on its way again. If the thing ever existed, it's now part of a Cuban '57 Chevy. --Vic |
