Vertical wind turbine with passive automatic furling
It furls passively and automatically to compensate for wind speed and direction. It starts generating power in 3 mph winds.

*Nice toy. Only those who MUST be self-sufficient from the power grid and live near the coast should install a large wind turbine.* In principle, however, PV modules generate green electricity at approx. 2% to 5% of the cost of small wind turbines. In addition, 99 out of 100 small wind turbines no longer function after 10 years due to the extremely gusty wind near the ground. PV modules, on the other hand, are extremely reliable and low-maintenance.
😢@@michaelvanallen6400 it was just an experimental model to prove that Savonious/drag vawt can achieve TSR greater than 1.0. Nothing serious. PV modules are good when the sun shines. Wind power can be captured at night. You need the proper location for wind power. And you are correct that wind turbines need a lot of maintenance.
Variable. Maybe from 2 mph to 8 mph.
What’s the wind speed?
Unfurling vawt looks cool but a series of the same hung on a tether together are likely to clash with one another . It is better to have them mounted firmly at both ends and the whole arrangement can be made to swivel to face the wind always
@@AnandDharwar If they are spaced properly they will all seay together like a field of wheat.
Imagine a bunch of these on the line all generating electric power.
Wind speed is miles per hour
After running in strong winds, I found that the horizontal carbon fiber rods that support the top and bottom of the sail had fractured due to flexing. It didn't flex very much and I thought they were quite stiff but they did.
Huge vibration. Either you need one more bearing at the top or shorter rod.
Interesting design. But the revs are too low
Yes. But revs depend on wind speed. Torque can be converted to revs easily.
Nice speed. How much rpm ?
Never measured rpm.
Hi :) Good job ! :) How max power ? Regards Paul P. = SUB + 👍🏻
Never measured. It was just a turbine experiment.
How did you make this?Where did you get the parts from?And how can you connect it to an electric motor
The blades are fabricated from A polypropylene sheeting called Coroplast. The generator is a stepper motor. The housing is a tuna fish can.
Wow! Just... Wow! That's a reeeeally clever gambiarra! I love it!
regarding your latest video about the 1.5v to 150v converter (has comments turned off) just wondering how many turns you had of wire you had in your electromagnet? loving the videos btw!
Sorry , had a troll. 275t of #36 wire
Another useless video. I’m going to get off your boring page and look at some paint drying up.
Good idea. try big one (dia of turbine) to get better result
The TSR is highest with low wind <5 mph, it drops considerably above that, but the torque is very high and a transmission would work to raise the output rpm
Good job .
The fittings, pipe and glue.... You can buy a similar stand for $10. Now, if you took black iron pipe and made a steam punk stand, that would be cool!
I didn't want to give money to china
Nice, since your comment on my video I've been trying to imagine how you built it 😉👍
Dope
Nice
The wind speed is 5 mph
I wish I had better software to make this better
Ok so # falls on weight what force rotates this thig ????
Human labor does. That's what the "charging handle" is for. Need to charge the battery? Rotate the handle 180°
Just have to rotate it a half turn once in awhile to recharge it. Biggest hurdle is the screw drive running smoothly.
I just asked my buddy yesterday if we could harness the power of gravity, since it is always pushing down, nice, thanks for this video,
Hydroelectric dams.
Video says that was 3.03
I must have stopped it just before that; how did you measure wind speed and whats the diameter of the turbine? Is that black fan in the background pointing at one side of the turbine your wind source?
The fan is not in the picture, it's way to the left. What you see is an exercise machine. Diameter is about 24". The air column from the fan covers the whole turbine not just one side.
Ahhh; it just that the blades are flipping at startup just where a fan from there would make them taking into account the wind spread. @@justtinkering6713
I thought I could hang a bunch,run the output wires down the cable and make a wind farm.
This was done by Caleb from our forum, he didn't supply the tsr. He doesn't publish on yt anymore so I copied his video from another hosting site. Url for our forum is at the end of this video.
He would know, too bad it has those big blocks holding the H arms they probably slow it down some, would be great to see a 3 blade; tell him to get busy and say Hi LOL
@@itsandbits1 He is in the process making one even bigger, but 4 blades. He plans to pump air for pond aeration.
Almost all two blade vawts vibrate, an odd number of blades is better, it was just an experimental model. The newest version has 7 blades, and is much smaller. His new YT channel is michael edward .
Genuinely cool concept; you can run an led off each leg of those stepper motors; Interesting thought about the self furling
what TSR did it achieve?
3.3
did you calculate the TSR? You're getting about 45-50rom
Caleb said TSR was about 3.
This is awesome to see. I’m working on a 3 blade one using a trailer axle and brake hub. Did you find balancing the blades difficult? Where the pivoting arm connects with blade? (In front or behind blade edge? ) counterweight distances etc. I’d love any tips you can offer. Thanks bro.
No problem balancing. The rocking arm connects at the leading edge.
@@justtinkering6713 Awesome. I’d like to connect just behind the leading edge by 10% of chord length, so I can use a smaller counterweight. The 1200mm x 400mm blade hopefully still allows pivoting properly. Thanks for your help.
I think the patent has more info. You can also post a message to Peter Sharp. He has lots of info.
You could join the forum that has Peter Sharps papers to read. Last few frames of the video
Awesome
Those blades are really moving! I think that you are right. Thanks for the update correction. I'm not aware of a Sharp VAWT that is bigger. I like it. It might be fun to connect it to a rotary displacement pump so see what sort of pressure it could produce. There is a big need for reverse osmosis desalination around the world and the Sharp VAWT seems especially well suited to that application due to its strong torque. My biggest model was 4 feet wide with 2 foot blade spans, and 2 blades. I used it to propel a model land yacht in all directions to the wind. Due to using only 2 blades, in a strong wind it would hop along due to the drag pulses lifting the windward rear wheel. That slowed it down. It was geared too low to get full speed, which would be half the speed of the wind.
Not bad. Good job.
Thanks
Nice experiments!
