Small Sharp VAWT

A small 600 mm diameter by 400 mm tall Sharp style VAWT. The three wings have a chord 40 mm each for a solidity of 0.20. VAWTs typically have trouble starting with such a low solidity, but the pivoting wings of the Sharp VAWT allow for easy starting.

Those counterweight arms are real short. The lightweight balsa blades are quite a benefit. It can adjust real fast. Good job. Do the blades have fiberglass fabric and resin? I wonder what the tsr is.

[@MickEMaus3000]

No fiberglass on these; just a little clear Minwax stain/sealer that I had sitting in the basement. I'll have to take some wind measurements and estimate a TSR.

nice build; looking forward to seeing some power; same generator?

[@MickEMaus3000]

Yes, the same generator. I used the same CAD model for the center part of this (just a little shorter) so the hole pattern was the same. The diameter is larger, but I'm hoping for a bit higher TSR. So maybe the rpms will be similar. The wind wasn't great at the time of filming, but there was a puff that made 0.9 Watts for just a few brief seconds.

Brilliant.

[@yvanpimentel9950]

To me, the blades should be at least 5 times wider. Vertical windmills are better at low R p m , And two more rates

[@MickEMaus3000]

I suppose it depends on the job. This is the lowest solidity turbine that I have ever built. I like how it is less obtrusive, and the speed helps in making electricity. It also uses less material. If I were to make another one, I'd probably have slightly wider wings; maybe a solidity of around 0.25.

Hello Michael！, your video is very instructive, can I share it on my social media, I will quote your video link and write your signature on the first line. I am a researcher from China on VAWT. Looking forward to your reply！

[@MickEMaus3000]

Sure.

And all they want to install it in US, where people with money and market already full, while place for self-promotion in Ukraine where people have no money right now. Later they will whining about their startups provide nothing while idea was great.
