Hi Flux.
Thanks for your coments. I've thought of doing truck testing also. Although the mph #s would be scewed from the cab over thing it would bring in some real wind and higher wind speeds for compairison.
As per my carved wood blades. This is the first carve blades I've built.
I have Hughs book from several years ago and I tryed to follow it as best I could.
I would like to test a set that Hugh built himself. That would be nice.
I did a post the question and asked Hugh if the blade I carved was good enough but I got no responce. It looked correct to me and ran very smooth.
As per my coils. Hugh asks for in the 12 volt version 85 turns of 16 ga. wire.
I wound 2 in hand 85 turns of 19 ga. 19ga. is 1/2 the circular mils. of 16 ga.
I brought all 4 ends out seperatly so the coils can be perelelled for star conection or siresed for Jerry rigged conection.
This was great. One stator that can be configure either way. There was a slight increase in power in the Jerry rigged conection. I'm convince there is also less heat. I also think there will be less coil burn outs with my configureation.
My thermal test indicated that. Over 1600 watts in the big NW storm a few years ago with my littel 8" duel rotor without a burn out helped in that belife.
It does seem no matter what I do I do get taken to task from other board members.
Thats good and OK. I don't mind. This keeps the chalange and the research going.
First the truck mounted test were deemed inacurate and I agree. Now the wind tunnel is deemed not real world and again I agree.
But what these test do show is a preformance diferances at specific wind speeds of diferant blades and alternators.
I do wish some other people were doing the same tests so they could get some of the responces I get.
I would love to share in the agree or disagree or your a ginius or your a nut case responces.
But I don't mind. I'll just keep doin what I'm doin till they kick me off the board LOL?
I think at least I'm trying to find the answer to the question. What works best?
Thanks agian Flux your my guiding light and mentor.
