DIY Wooden prop wind experiment II

http://iheartheli.com 5-10 mph wind today, test yeilded 0.3 Volts on the Hanger 9 starter motor. The motor spins ~ 5K at 12 volts or ~ 400 rpm/V (kV) . 0.3 * 400 = 120 rpm or about 2 revs per second. It could easily go to a volt or so in higher winds. I think a 10:1 gear ratio would be about right for it. The blade was made from Dan Rojas instruction videos (GREENPOWERSCIENCE) http://www.youtube.com/watch?v=uT2y5JJ24f4 I made mine 6 feet in length, 15 degree angle w/ 1/2 inch edge.

Gday Rich. For a "slab" of wood, that's quite impressive!

@brotherblonde Thanks. The blade was made from Dan Rojas instruction videos (GREENPOWERSCIENCE). I made mine 6 feet in length, 15 degree angle w/ 1/2 inch edge. I added a link to the build vids in the comments above. I'm still experimenting obviously.

Nice work!

hey thats actually pretty good considering that its not on a pole a good 15 to 20 foot pole would give it more air to run with and the real wind generators are all geared to the generator and they all have breaks to keep the blades spinning at one speed but still that aint that bad good video
