This is cool... But in regard to the first model needing to be steered, couldn't you solve that issue by building it on a swiveling base and putting a flat, vertical fin coming off of the Z-axis so it is always pushed in the direction that the wind is blowing? Similar to the model of a weather vane.
Coool showing ,what he isn't telling u is it would take some 10 or 20 times the size of the windmills in this video ,more or less great yard art which is very enjoyable to see.Thanks for the showing
@4245047 same here, i'm building today or rather helping my daughter in her windmill science projects and after an hour watching videos, this video is tops in its simplicity, impact and clear message. most impressive! i've bookmarked this video to use as a sample of how to make a really clear video for my clients.
I thinks this is a very well done video explaination of wind generators.I wonder if theres a market of adapting this technology to sail manufactuers for sailboats?
have you applied a motor to it yet? mine isn't a vertical, ad hauls butt till I add the 1 to 5 gear ratio to it and the motor. I had an idea since it's easier to reduce the gears from 5 to 1 than 1 to 5, we should be able to use a pully system that gradually uses the gears to pull up a 100lb weight with ease, and hit a lever to drop, while producing enough rpm to charge a battery bank, this way all of the wind is utalized for power at some point as a cycle, instead of relying on high wind only
Hello. A freind and I are working on a school project were we are supposed to build a windmill with stuff from a recycle center, but we are able to buy stuff if we need them. We got inspiration from your Vertical axle windmill. Do you got any good designs or plans to build a generator?

It would be really helpful to make a video for what is used to make a magnetic generator for a little wind turbine. I have neodymium magnets and very thin copper wire (about .006 inch diameter), but not having an electronics background, I don't really know the other components, and that would help. Also, there is a two part sculpture compound called Magic Sculpt that you can hand mix and form and it becomes extremely rigid - you might be able to use that to form some of your moving pieces.
Hi - I'm planning to make a little arty wind project - I thought about the flutter one, and I think you might be able to make one maybe with a helium balloon on one side and maybe a spring or counterweight on the other side if the flutter turbine just causes a mechanism to back and forth - you could probably get that with a balloon and an opposing force - that might also work pretty well in really low wind areas. Let me know if you think that might work. :)
With the traditional windmill one does not have to turn the blades in the direction of the wind. All you have to do is fit the back half of the windmill with a Tail (like in a plane). However what you have to make sure is that the wind mill is mounted on vertical shaft that allows it to turn in any direction. Also the shaft should be connected a little off center of the windmill, slightly more towards the blades that will allow the tail to swing, making the blades face the wind at all times. thx
You could store the power using deep cycle batteries. Especially if you live in a place with inconsistant wind gusts. Or maybe use solar as well as wind to keep a steady supply of power?
using your scaled model sized turbines, which ones would would typically create a larger moment at a constant wind velocity, the vertical or horizontal axis turbine?
hi there amazing stuff. i just would like to know wich motor u used and if possible where can i get the design for it (vertical axis windmill).thank you

hay i have to do this project for school and since the econemy is becoming crapy i thought itd be nice to make one of these for my house to power some little devises to at least make somewhat of a difference in my parents bill can u explain to me how to build one or just telll me wat site to visit thanks
the last one you demonstrated? The Flutter generator, say you had a small drone plane, and using this theory could you add enough flutterers to it to run the small electric motors or atleast charge the battery/capasitor enough that it would not lose power and could maintain flight until the engine failed?
Ever see a kite with ribbons on the ends? I think it wouldn't cause too much drag. Think of a bird and it's feathers. But imagine generating static electricity from wool and latex feathers that could generate enough power to run a small motor. Think of it. So long as there is wind passing through the feathers causing them to create static generating enough power that can be stored in a capacitor or small battery to run an on-board motor that would power the craft indefinitely
+Erik Palafox: I can see the possible potential of your idea, however I see big problems obstructing a positive outcome. 1A: Aaron Keith was right. The biggest problem is the drag added to the vehicle. 1B: The amount of Work being done in generation of electricity would not out way the amount of work being exerted by the motor to keep the vehicle in flight. How do I know this? because the transformer that would do the generation would be heavy and not 100% efficient. Work-in will always be more than work-out. The best case scenario would be an extension to the range of the vehicle. 2: A kite doesn't fly... it hovers (erratically). Also The reason a kite stays in the air is due to pressure from wind. A kite would be a great tool for utilizing the flutter design though, if you could find a way to make it stay up without having a human control it 24/7...and the control mechanism used less energy than the kite produced... 3: Birds... let's not go there. if you tied kite tails to the back of a bird it would just need to eat more worms...
I see windmills can be used as temporary power source during a storm. There's lots of wind and if the power company cuts off or the electricity just goes off then there's an alternative,
wow))i like it very much!u r genious)this is very good input towards clean environment!!i am interested..how much energy can they producE? and if the energy can be stored..in a battery maybe?
1:30, thats why you build the mill on top of a rotary base and have a fin attached behind the wind mill that will line the windmill up with the direction of the wind
Thats great Man, i really enjoyed your video and its thumbs up for sure! the Wee flutter generator looks like one that any one can make with the most basic of tools, just a question of where to get the linear generators or i guess these can be hand made too........
can you not marry the vertical and horizontal shafts to give you an automatic into the wind set up.a bit like how they use them on yachts steering for auto pilot???I would think that would give you highest generation profile.hats off to trumptons windymiller,a truly inspirational figure from my childhood .
Say you were in a zombie apocalypse and you needed certain things to be charged with something like a car battery; could you use a windmill to charge it? If there is enough wind around obviously.
hey can you show me a video/diagram of a windmill being used as a water pump.. is it posible to make a water pump windmill in small scale like the ones in this vid.. thanx. cool vid btw
I thought that it looked week too. But I do think if you had an area that had very little or very light wind it would harvest it, and eventually your battery will be charged. Just sayin.
I made one of those one of those once, out of wood. It was 29 feet and 7 inches tall and was a vertical windmill that spun on a custom made ballberrings and shaft that you could attach various machinery and devices to. Each wing was 21 feet tall and 9 feet wide. Unfortunately, a storm ended its proud tall life to a pile of splintered wood. I only have one photo of it -_-
Nice video! Kudos to keyofdavid888 for mentioning the phenomenal Nikola Tesla! Every time someone throws a light switch or plugs in an appliance, you can thank Tesla for the Poly-Phase A/C power system that is delivering the juice. Were he living in this time, the technology available to him would have made his quest for wireless power delivery across the entire planet feasible! Politics would still of course be an HUGE issue, but the technical requirements would have been at his disposal...
Unfortunately the problem with the vertical axis turbine is that half of the assembly is moving against the wind as it turns. Obviously the rotor is cupped to avoid this partially but on the horizontal axis turbine the blades are actually airfoil shaped just like an airplane wing & so once its spinning a certain speed the blades create lift & pull themselves along, speeding up the rotor & producing more power.... the rotor size to power produced ratio is much better on horizontal axis turbines..
I am sorry but I was unable to hear a lot of what you said due to the volume. seemed your fluctuation of your voice was not picked up very well on the video volume. i feel i missed some interesting info
Thanks for the link pal, i already know the site and the guy that produced it - he was on V-radio show another day - i've watched the frist bit though - 13 hours is quite some time, ins't it? Take care :) FS
There's no problem with a horizontal axis windmill pointing to the wind. Ever heard of a tail? A tail on a windmill would be a fundamental piece you left out of the horizontal design. So, the only problem is something that was left out? HAWT is standard in all wind farms, that's because its design outperforms all others..
The pitch works a little like having a gear ratio. Putting the blade at 45 degrees to the wind means that the blade will try to go the side as fast as the wind goes past. For flat blades this is a good angle to stay near. You can make it so that the blade is 30 degrees to the wind if you need more RPMs or 60 degrees if you need less. Remember that over that range torque times RPMs is roughly a constant for a given wind speed and diameter. If you have the means to do it, making the blades curved like a wing gets a little more power out of the wind. The flat side of the wing is the side towards the oncoming wind. Also as you go out on the blade, the distance it needs to travel gets further. A twist that makes the blade near the hub at 30 degrees and near the tip at 60 degrees makes a better blade. Given that the wind is free, however, it is not needed to do a fully optimized design. Wasting a little wind is no crime.
is it also possible to have the blades loose so they are able to self adjust to wind direction if the turbine is fixed or just loose in case of swirling gusts?
