This was definitely a little bigger job than I had anticipated. Not all that difficult, just more than I had thought. 20' Koenders double diaphragm running two Vertex 9" diffusers. When it looks like it slows down, it doesn't, it is an optical illusion kinda like an airplane prop I guess.

Did you take a video of the bubble pattern?

That would be interesting to see as well.

Also, how slow can the windmill turn and still have good bubble production?

Yes pay attention to the bubble pattern in a slow 4-5mph wind.

I saw nothing but the windmill spinning.

Wow- if you have a wind like that all the time bubbles shouldn't be a problem .

Koenders says the windmill will make air in as little as 3-5 mph winds. I have no way to measure the wind speed up there so I don't know exact numbers of what we have up there. I do know that it spinning like crazy way more than not.

I did not video any of the bubble pattern.... With all the discussing I have done here, I don't remember anyone telling me that before lol. looked to me like pretty good size circle of bubbles above both diffusers. I will be back out there in Septmber and will video them then. What exactly am I looking for?

10-4! Thanks Bill! With one of those charts I can definitely figure it out!
