been working on a lofty goal to build a outer ring turbine generator. been having a bit of difficulty and looking for a bit of guidance.
Project: 27" diameter shell (outer ring) with 27, 22 g., 250 wind coil with a oval 1/2" x 1" center and each a little less than 1/2" think. they fit nicely around the outer edge of my casing. with a steel back plating 1.25" wide

On the inner turbine, I have 36 magnets, 1/2" x 1" x 1/2". with a steel wire (16 g) backing I ran around the rim about 6 times.
All my coils are placed in the same wiring config - positive lead to the left around the outer ring. I have configured a 3- phase STAR.
there is about a 1/4" space between the magnets and the coils when assembled
A1+ to A2-, A2+ to A3-, etc...
When i try to test any one phase i get fluctuating readings. from neg to pos - just a few v each phase.
When i connect all three phases I get only about 5 v total but nothing steady... have a small led light that flickers as i turn the center wheel - at about 100 rpm.
I expected quite a bit more power and think my wiring is wrong or my coils are wrong. My goal with just a light spin was about 20 v. Am i off base that much?
here's a video of my first test but as you can see, very poor results. the video is over 40mb.

thanks for your help!
