Rotary sailing and wingsail research
Testing the Direct Upwind 18 inch rotor model
At Eaton model boat pond Norwich. The model is tethered otherwise it goes directly to the UPWIND end of the pond. Sometimes the wind drops and it just stands still, but in gusts it goes strongly directly into the wind. Best at 2.20

This test is to demonstrate that a small wind turbine can power a much bigger boat directly upwind. This is a low speed wind turbine with a tip speed ratio of 1:1 When the line goes tight the boat is pulling directly into the wind.

Can heavy weights be carried directly upwind using only the wind? Here is the test which proves it.
Increasing force in the opposite direction

This video illustrates 2 things. That a craft can be powered by a force in the opposite direction to its travel. That the weaker "pull" can be converted to a stronger "pull" without adding any extra energy

I wonder if you used an aircraft wing for a sail in the front. and you did a tac, if the combined increase in speed would empower the fan to go faster. A synergy effect so you could go much faster in a sharp tac.
I am thinkng it needs tuning. The fan is going too slow so using a smaller water propellor could let everything go faster and more power. like a transmission..
As an ex engineer, i'm impressed with your creation. Pitch adjustment is a stroke of genius.
I agree!
I am really not convinced that this can progress 100% upwind, at least not with the movie I just watched. I would be happy to offer the designer $100.00 bet if he can progress 100% upwind for 15 consecutive minutes. I may be wrong, I will happily pay the $100.00 if that is the case. Think about it. On a super calm day with no wind pull the boat at 15 KM/h so you have 15 Km/h of wind since it can progress 100% into the wind it should keep going forever... Are you sure?
Well done!!
cleaver man
Lord briton is a tool
Have you done any further development on this design?
Who is the assclown that music in this video? How childish and unprofessional it is!
Ideal for haircuts, short back and sides ?
Since the vector direction of the wind flow and the boat vector are orthogonal it's believable technology I'm almost inclined to think it has better power then a sail is that correct ?
Thank you for sharing this great example of your creative engineering, great work. Peter, Know that the Light of your being is a blessing to everyone on your journey. Shine on
I wish you had a light weight streamer on the boat for demonstration. Or several on shore.
Всегда нужен ветер , притом сильный. Иначе движения не будет.
IMPOSSIBLE. If you could sail DIRECTLY into the wind, you could build a perpetual motion machine.
It doesn't work like that.
Haha..you clearly do not get it.
This is not perpetual motion, much of the wind energy is being lost but there is still enough to drive this small craft forward, it’s perfectly possible and wholly unsurprising.
@@charleslyster1681 not directly into the wind?
@@scott4981 directly into the wind is perfectly possible with this setup; it is a fundamental misunderstanding to think this is a ‘perpetual motion’ claim. Perpetual motion would be a system where energy is put in once at the start and then the system runs perpetually on that fixed amount of energy. None being lost as friction etc. That we know to be impossible. This is entirely different. In this system there is a continual input of new energy from the wind. Most of that energy is lost (as it is in a steam engine, car or most other systems) but enough is captured to drive the propellor. For it to work the thrust delivered by the propellor to the water needs to exceed the drag imparted to the rig by the wind and as we can see, it does. This thrust:drag ratio applies to ordinary sailing craft as well. A ship sailing close to the wind is slowed by the drag of its complex traditional rig and the course made good is much further from the wind than the angle the ship is pointing at. We could think of it another way. Suppose you had a car pointing into the wind with a windmill on top connected to the wheels by fixed gears. It would be wholly unsurprising that as the windmill turned and turned the wheels, the car would move slowly forward. The boat case is the same but with less obviously rigid connection of drive to medium. ; it is not widely used as a way of getting around because it isn’t very efficient, fast or useful, but it does work. For this to be a perpetual motion machine it would have to move forward perpetually after a single puff of wind which then ceased.
I did a small unmanned boat about 30 years ago that would sail directly into the wind. Simple direct shaft between a large low pitch propellor and a high pitch windmill. Worked great! I like the ability of your craft to travel in different directions but still some things obvious to solve.
Turn downwind and those rotors will chop the skipper to pieces. Millions of people for thousands of years have perfected sailing and this nong thinks he has a better solution... S.M.H.
Tremendous fun until you get hit with that blade!
Interesting, less complex in handling than sails. How does it scale to cabin cruiser size, and is it any safer in a gust or storm than a mainstay boom ?
Great concept. Excellent video.
Yep, patented in America about a hundred years ago.
Awesome, thank you for sharing. How has the project progressed?
Yeah, that is so cool !! Nice prototype.
I love that people aren't just accepting technology as is and willing to do projects like these. They're not cheap nor cognitively lazy, and yet some of us still pursue them. Absolutely beautiful, I wish for more folk like this individual.

This is absolutely brilliant. Well done, and thanks for sharing.
Amazing…. In one sense, if your going directly into the wind maintain momentum, it’s like perpetual motion …. Genius.
I was planning to do something like a "Direct Paddle", where the wing-tips of the wind-mill reaches down the water, just a little bit, and paddles the boat directly forward. Of course the tips should be curved a bit accordingly. Maybe, you can give it a try...
Ingenious.
Excellent 👍
Is this is another perpetual motion machine, that like so many others obscures the real energy blances by the redirection of forces? The video shows no prolonged directly upwind travel.
This contraption doesn’t break any of the physical laws, unlike perpetual motion machines. Its function is just counterintuitive.
The propeller blades go upwind diagonally, just like sailboats do. The hull isn't an aerodynamic element, so it doesn't matter what it does.
Unfortunately not practical,, that's why, after many years,, you don't see them in every marina around the world
Very impressive. Keep up the good work.😊
cool I like it although it is ungainly
Good job!
Nice work!
Sell Dich nicht so blöde an. Nimm einen Derrius Rotor oder einen H - Roror und dann bist Du unabhängig von der Windrichtung. Peter
But it does not work
i want it true value

Peter, this is a brilliant invention. Will we ever be able to buy your fabulous invention commercially? I mean, I could theoretically build a version for myself for fun, but would much rather BUY a product that could be added to a boat in place of traditional sails...
value can buy with money😂👏👏👏🎉🎉🎉
THIS IS WONDERFUL. I DESIGNED MANY THINGS SIMILAR OVER THE YEARS, PEOPLE TREATED ME LIKE I'M AN IDIOT. HERE YOU ARE, PROVING THEM WRONG!!!!! THANK YOU SOOOOO MUCH FOR EXISTING!!!!!
a new invention from 1995?
i think a vertical axis wind turbine would suit a craft like this very well
That's what I was thinking. And then it could also be powered downwind, rather than needing to feather the blades. And it would be possible to install more than one - either geared to one prop, or perhaps each with it's own prop.
I'm not sure they are as efficient as a HAWT, so might not work very well.
downwind can be one advantage, but they lack in efficiency overall compared to a horizontal axis turbine. as for a horizontal axis turbine going downwind, simply put a tail end wind vane on it and the blades will always be facing into the wind.
Check out Walker Windsails. My father-in-law invested a lot of money in that. Lost the lot.
Low and wide wind turbines are better for ships. th-cam.com/video/cVU9a1N2BSU/w-d-xo.html
thats so cool i was thinking of making a remote control rover powered by a wind turbine like this
Cool, would you share the drawing mechanism ?
That's fantastic.
outstanding. I started looking at land DDWFTTW carts......... still trying to wrap my head around this all. THANKS!
Have you tried the Savonius vertical rotor? Same gearing idea but faster rotation. Works with all wind directions.
That is fascinating. I take my hat off to you Peter, for your ability, and dedication. Keeping that wonderful tradition of a man in his shed alive, and exploring posibilities.
What a wonderful comment. Thank you two :)
Wow. This is incredible! Do you think it could be applied to bigger yacht's in leui of sails? I, and I'm sure many people, would love to pick your brains and further discuss. Cheers Azza

The air blades would work better if the blades had twist to them like aircraft propellers.
