Experimental model wind-turbine boat

[srm13560]

...and turbosails are born... welcome !!!!

[c6rocks]

What if you want to go a different direction? Wait for a favorable wind?

[ZKMX7]

@c6rocks It's not meant to be a complete sailing solution. Just demonstrates the principle which can be applied to other boats which have the ability to sail on different tacks.

[dlstb]

I doubt the validity of this project. I'm pretty sure you need a guy with a fishing line at the other end of the water you are crossing to pull the boat across as the wind hitting the blades pushes back on the craft harder than the propeller can ever push you forward. It that weren't the case, then we could do the same with cars and we'd all do 70 mph down the highway without using any thing but our own airspeed.

[ZKMX7]

@dlstb You need to check out the other videos on my channel before coming to that conclusion. I've lost count of the number of people who have said exactly the same thing. They and you fail to understand that the power comes from the difference between the velocities of the wind and the water. In the case you mention about the car, the velocities would be the same so that's why it doesn't work.

[JebacPresretac101]

@ZKMX7 you mean the difference in viscosity between air and water?

[ZKMX7]

@JebacPresretac101 No, the velocity, not viscosity.

[ModelLights]

@dlstb Instead of having 'doubt's and considering yourself smart because of it, why not go get a basic education?  The wind isn't blowing the blades back, it's blowing them around. With the spinning and flow of the wind the blades need to be on a diagonal, but the force imparted by the wind is almost all pushing it around faster, not back. Use that to spin a prop, which has far higher traction in the denser water, and it will easily pull the boat forward against the small drag of the wind.

GREAT IDEA TAKING NOTE!

[skjevemartin]

woooow :) that is wery nice, youst whis that it was mine :P

[telchar186]

exelente trabajo ( cool work)

[olivercoles87]

Why did they bother teaching us conservation of momentum at school?!

[bradmacaboy]

if you had a variable pitch, and wider blades, you could sail downwind, having the wind push the static blades when they were in the no pitch position (that is, showing as much blade width to the wind). Of course, you could also reverse the pitch as well and get propulsion downwind, too. You could use a micro switch on a weather vane to determine the optimal pitch angle depending on the wind direction and the desired direction using a feedback control system........hmm

[hbunnie1120]

Just wondering how well does it sail down wind..?.. Just wondering. It is a very cool demonstration..

[ZKMX7]

@hbunnie1120 It's not really for downwind work. Normal sails can do that quite well already. It's just directly upwind is impossible for them. Some sort of hybrid might be a good idea. This for direct upwind with maybe wingsail for other points of sailing. Please check out my channel for other videos on this subject.

[Stoettax]

great job! whats the name of the song?

[ZKMX7]

@Stoettax Thanks. "All of Me" - Jon Schmidt - Check out jonschmidtdotcom

[Splitsquid]

Congratulations, Beautiful achievement. Can you steer it with RC rudders? Does it work in any other direction.

[ZKMX7]

@Splitsquid Thanks for your kind words. Yes, indeed there is a RC version. Please check my channel where you can find my other videos on the same subject.

[file83]

Hoax! You used battery power. Shame on you!!

[ZKMX7]

@file83

Please let me know why you think that!

[EyeSquaredAre]

@ZKMX7 "Think" might be too strong a word here. This person simply can't appreciate what's being demonstrated here and your video lacks the sex and violence needed to keep the attention of the average Youtuber. Your boat is cool, nice work.

[Ashitanoyuki]

how does it turn itself toward the wind? I dont see a tail thing behind the windmill.

[ZKMX7]

@Ashitanoyuki

The drag of the rotor itself works the same way as a windvane - it doesn't need anything else to keep it pointing into the wind.

[ej20daZe]

@ZKMX7 very nice %

[gaypotter]

@ZKMX7 AYE, it be true! I have seen a few actual wind generators work like that.

[xXDarkMidnightSunXx]

thats beautiful! :D

[Donsfast]

Works even better with vertical fan...then you can move in any direction.

[markfriesen1979]

but why couldn't you add this to a light car model and drive for free? and a little extra juice from solor panels.

[ZKMX7]

@markfriesen1979

You could. There is no reason why you shouldn't.

[Lucasquinamo]

Quite interesting! I've enjoyned!

[frilink]

You just gave me an Idea for my project

[sheerterror77]

have you tried this with a heavier boat?

[ZKMX7]

@sheerterror77 Certainly have. Check out my other videos or search under "windmill driven boat"

[saab93secv]

That's beautiful! I just had that same idea today -- awesome to see that it works!

[Reallaty]

song name?

[ZKMX7]

"First Run"

By Jon Schmidt

(New age piano player)

[Reallaty]

@ZKMX7 i dont think thats the song i searched and it sounds nothing like this

[s0undw4v3ultra]

that it amazing i thought of somethinglike this when i was 4

i never thought it be possible

[vroom350]

Its very nice free energy depend wind!

[Alomphega]

Ok, thank you very much for your answer.

Do you think to show both the windmill and the propeler on a next video ?

[Alomphega]

Hi Peter,

Good job, so I have a question : is there a propeler under the water ?

GC

[ZKMX7]

Yes, there is a propeller, otherwise it could not go directly against the wind.
