Thats super...
so am I to understand that the 2 blade prop with the flattest pitch wins here?

Pretty neat... as neat as the windmill is the good data you got on different prop configurations. Congratulations!!!!

Dan,
Yes, the two blade prop with three inch pitch produced the most power. Maybe one with a lower pitch would be better, but I didn't have one to test. Also I learned that the airfoil on the back of the prop is backwards with the sharp edge leading.

Both of the three blade props started the soonest. The fan blade starts spinning with very little wind but is so inefficient the speed levels out very quickly, limiting the power output.

Mike R....

Very neat small project turbine...

I run a small educational non profit called kidwind (http://www.kidwind.org) that is trying to put more wind energy science into classrooms...

I was wondering what you did with your daughters project after it was completed...if you are looking for a place where it can live on to education many others might I be so bold as to take it off your hands...

I could pay you for materials and shipping if that is needed...I just thought it was really neat and want to share with other teachers at my workshops....

I totally understand if you do not want to part with it....but I thought I would give it a shot...
