New Large Sharp VAWT - First Power
Some voltage measurements, and catching a brief glimpse of the vawt producing power. A smaller pulley is on order to help boost the generator speed and voltage so it will deliver power at lower wind speeds.

A quick look at a 1.44 m^2 Sharp VAWT. A more detailed video will be coming soon.
Street Light VAWT

A VAWT designed to drive a COB LED. Halfway through the video, I changed the turbine to one I had printed in red filament. (The orange rotor did not look as good) www.thingiverse.com/thing:6828439
Higher Voltage VAWT in the Wind with LED Load
มุมมอง 1.4K2 หลายเดือนก่อน
Just a few short clips of the higher voltage vertical axis wind turbine with an LED load in stronger winds. The coil is designed for a 15.5 volt load, so it has a fairly high impedance. I suppose the set up could be improved slightly with a coil wound for a 10 to 11 volt load. When it was dark out, the LEDs were bright enough to cast shadows on the ground.
Millerinski VAWT
มุมมอง 2.4K2 หลายเดือนก่อน
Just looking at how two turbines spin under similar conditions. One is like the Yin Yang VAWT with just a channel through the middle of the turbine, and the other has scoops in the sides and resembles a Ugrinski. I thought it looked like a cross between a Miller rotor and a Ugrinski, so I called it a Millerinski. Just a note: this video was from before the "Higher Voltage VAWT." It was an exper...
Small Higher Voltage VAWT with no Electronics
มุมมอง 6K2 หลายเดือนก่อน
Just a follow up to the previous video. I made a new coil with 699 turns of 38 AWG magnet wire to get the voltage up for charging a 12 volt battery without the use of electronics. I decided to simply light an LED light using the turbine as opposed to charging the battery since the current to the battery would be so small even in a good wind.

New Large Sharp VAWT - Spindle Construction
มุมมอง 4252 หลายเดือนก่อน
I'm in the process of building another large Sharp type vertical axis wind turbine; although, not as large as some of the previous ones. This is a look at the spindle/generator assembly. I still have some work to do one the turbine, so that video may be a week or two away.
Small Higher Voltage VAWT
มุมมอง 2.5K2 หลายเดือนก่อน
A look at a small vertical axis wind turbine designed to drive a DC-DC boost board in order to charge a 12V battery. Details are given about the generator design and testing. Long story short, I'd prefer to simply charge the battery directly off the generator due to inefficiencies in the approach. But I thought I'd throw it out there.

Qualitative VAWT Comparison - YinYang-ish and Ugrinski-ish VAWT
มุมมอง 5532 หลายเดือนก่อน
Looking at how two turbine behave when exposed to the wind. One is similar to the Yin Yang VAWT from a previous video, and the other is similar to a Ugrinski VAWT. I wanted to see how well a turbine would spin with just the center portion of the Ugrinski only opened up for more air flow. And then added scooped out sides, but no curl like the Ugrinski. It looked a bit like a curvy Miller rotor, ...
Yin Yang VAWT revA
มุมมอง 2.6K3 หลายเดือนก่อน
I made a Yin Yang VAWT with straight wings and a slightly larger diameter. It has difficulty starting but does well once it gets going. Next I want to try putting an offset of 90 degrees between the lower and upper halves to help with starting. I also have to install the coil (200 turns of 32 AWG magnet wire) and check its performance.
BLDC VAWT Final Version

A small drag type VAWT designed for a small BLDC gimbal motor. Waiting for wind to see if it will spin. If the cogging is too great, the turbine will be lengthened and/or plates added to the ends.
Micro Sharp VAWT in Good Wind
มุมมอง 5744 หลายเดือนก่อน
A collection of video clips taken in a good wind of around 5 to 7 m/s. The output of the motor/generator was fed to a three phase rectifier and then to a green LED. The LED would barely glow at times giving a rough indication of the voltage being generated. The BLDC motor is rated for a higher speed and is perhaps not best suited for this application. However, it does generate electricity. The ...
Involute VAWT

A vertical axis wind turbine that incorporates segments of an involute profile. It works for the most part, but I can't speak to its efficiency. I just wanted to throw the idea out there. stl files: www.thingiverse.com/thing:6728505

We had some sustained high winds today. And by that I mean the wind was over 3 m/s for over 3 seconds. Here is a little video of the event.

should use Tesla Bifilar Coils, and earth ground
Is it a toy or some current generator? If so, why don't you show the meter?
It didn't have a coil for it at that time. I just wanted to see how well it spun. Wind is hard to come by in my area.
If you are willing to share, I'd like to hear more about how you figured the circumference of the form to wind your coils.
What I've been doing lately is take twice the diameter of a magnet times the number of magnets and then add 15 to 18% depending on how much I have invested in the coil fixture and wire. If I'm a bit nervous, I'll go with the larger figure.
I'll tell you something, I did a simulation of the yin yang shape and it was less efficient than the semicircular shape in the Savonius turbine.
Good to know!
*Reality: All tests show, that VAWT are inefficient toys!* *Due to price decline solar panels generate at least 10 times more green electricity with same investment! Reliable for at least 25y - maintenance-free.*
Very nice.
Nice ! I'l try to play around with one wing Sharp prototype on day. I've got a little question, what's the schema of all your electric/electronic composant down there ? Are you connected to batteries and the grid also ? I'm struggling to find information to merge solar & wind turbine, electrical way speaking, with an hybrid system. Thank you for sharing that !
I've got one charge controller that came with a windmill that has a dump load, and another charge controller for the solar panel. Both just connect to the battery. But sometimes it seems like they conflict; the solar charge controller would keep the battery at 14.1 volts while the wind charge controller wants it at something like 13.7 volts. I decided to get a single controller that takes both solar and wind. I plan on installing it soon now that the wind turbine is complete.
@@MickEMaus3000 Yeah, That's the ijssue I was thinking about. I'm thiking taking a Growatt hybrid inverter with 2MPPT for my solar system. But then how to merge it with a wind turbine... I'm struggling there.
Not too much power it can produce! 😊
@@jamesyao9199 yeah, but solar in winter or the night will always be worst than wind ! 🌬️ Even if wind can’t go high power. I plan to build a 800W. So average of 200W with normal windy conditions !
@@jamesyao9199 No wind, no power. This is not a good location for wind power.
Interesting. One the wings came off my junker sharp vat , wind cranking lately. It's too cold and I'm to lazy to fix. Goes around ok with one wing.
I'd love to see it.
Nice; good to see its holding together too
They look Cool and the are running!!!
Looking good when it gets some wind howling! Is it doing anything or just running free?
The generator is hooked up to the charge controller for a battery. The wind didn't last long enough for me to see if it was pushing any current.
Wooooeeee, look at it go 🤯🤯🤯👍👍👍
It would be interesting to see a C-Rotor design analyzed
How much watts it produces?
There was no generator on this one. This test was used to help design it. Here are links to videos about that: th-cam.com/video/cQRBJx5AvMU/w-d-xo.html th-cam.com/video/77DJ-c1LSNg/w-d-xo.html
do you plan to release plans or models for the built? Nice video
The plastic parts are on Thingiverse: www.thingiverse.com/thing:6717893 But the rest of it would take more describing than I'm prepared to do.
Any updates about generation ? Do you have tachometer ? How many RPM you can get on this kind of wind ?
No updates yet. It takes a bit of wind to get the voltage up to where it will charge the battery, and we have not had much wind this summer. I'm working on a larger version, and hope to get back to this once it is completed.
👌
About 250 bucks fancylooking garage produce nothing!
It won’t produce any power even install on my driving car !
This Chinese garbage is just a scam! Throw it away!
I believe you would have much better results if you would use a C-Rotor wing design as they have been found to be a much more efficient design.
E for Effort you may want to look into a C-Rotor type wing though.
The wind is really much too noisy, maybe you could try this indoors next time to keep the noise down please?
Yes, its a joke. Laugh.
You should look into C-Rotors they are super-efficient.
Great looking design! I really like your alternator. I'm curious how much the RPM is effected when turning off one LED.
I'm not sure, but all the files are on Thingiverse if you'd like to experiment with it.
I’m pretty sure you might have said something when you walked out into the wind but I didn’t catch what you said😂
I think I was commenting on the wind speed. Just guessing that it was around 25 mph.
It works great. Is the thrust bearing a single ball?
The upper bearing is a ball bearing that takes the thrust, the lower bearing is plain bronze bushing.
working nice! I wonder if you put a small cap on each side if it would help as someone else suggested on another vid?
Would that work on an AC circuit? The flickering is only visible with a video camera. The light looks like it is on continuously to the eye.
@@MickEMaus3000 I think they should; you're essentially giving it dc pulses if you fed one leg then the other leg to the light on each side. I could be wrong but... If the light is continuos I guess there's no need
@@itsandbits1 Persistence of vision. :-)
@@itsandbits1 you would need diodes orit would be like a short circuit
Try adding a step up buck boost converter into the equation
Did it come with a three phase rectifier? And try experimenting with dc to dc buck boost converter. Maybe it might work then?
good looking little unit that works 👍
I think I can make it just a bit better. :-)
@@MickEMaus3000 sure, put a little 6x6 3 wing Remkick up there Hahaha
Maybe use a capacitor on each LED? Just to get a constant light
This is AC voltage, so either back to back electrolytics or some sort of foil capacitor I suppose.
Are they wired opposite, so one cob gets the positive cycle and the other gets the negative cycle?
Yes
Make them slanted yellow eyes for Halloween
Everything you are doing is electronic!
That can be the most challenging part.
Water tower!
chat gpt gave that software ansys-fluent for simulation
Can u change design such that make air go down instead of going out ...air compressed down and vent down. Will add top section with single blade but only one direction it can move. infact all section move one direction only
Also can u make it rotate only one direction?
i was thinking if it rotate where did it get the wind? it will not take wind after certain speed? This design has issue
SPEAK UP..! Even the closed captioning doesn't understand alot of the spoken words.
do you have na URL from where to get the 3d model? :D
Thank you for this video ❤
Very cool. Now I need to watch the rest of your vids.
maybe next time try not recording while there are banging noises in the background
Sounded like a little one being "constructive"... likely an engineer in the making.
It’s ping pong
Is there a way to measure wind pattern so you can design effective VAWT blades
I think the Millerinski will pull better but you should submit them to "this is Max " for testing :-)
What is that for, the sound wasn't good
I agree. A lot of good data with his new dynamometer. www.youtube.com/@hellothisismax/videos
Cool. Your 3D printer must be glowing infrared.
What the hell is a wind turban?
It is an engine that converts wind into mechanical power.
