That 100 turn of 14 gauge was for 12 coils, 16 magnets, since your not doing that anymore:
Number of coils = Number of magnets X 0.75 (to get a 3 phase setup). So that gives us 32 X 0.75 = 24 coils. Each phase will consist of 8 coils. You can number your coils with 1/2/3/1/2/3/1/2/3 and so on, every 1 goes together, every 2 goes together, and every 3 goes together. You can connect them in series or in parallel, depending on your needs for voltage versus amps. Now, as far as number of coils and thickness of wire, I can't really say, because I haven't had much experience with 32 poles dual magnet rotors (how much voltage an rpm will produce) So, you'll need to do some tests on that once you get your alternators ready.
Flux explains how to figure alternator output and stator losses quite well in his reply to my posting here http://www.fieldlines.com/story/2005/12/15/223045/99
What I can tell you is, I'd keep the center hole equal to the magnet face, the coil thickness (the legs) will probably end up being optimal at 3/4", and as far as stator thickness goes, I'd shoot for 1/2", it seems to work good with those magnets.
Given that space, as far as number of turns/thickness of wire goes, well, VAWTs aren't exactly know for their high rpms, so, chances are yours will spend most of it's time in a low rpm state. You should therefore optimize your setup by choosing a bit lower cut-in then HAWTs have (so more turns of thinner wire). It would prove to be quite inefficient at higher rpms, but since your not operating at TSR 6-8, and you won't be hitting 500 rpms, you should be allright. (Unless it's a SUPER VAWT, lol...)
Keep us updated!
