Green: by now, you've had both sides of the alt discussion presented to you. I do not know where you live, but if you want to try one,
I will give you one that has a big neo ring in it, and is rewound. It'll just cost you shipping. I played with them a lot, and you can get power
out of them, but even rewound, it takes some rev's to do it. (14.7V@400 r.p.m.). Having said all that, I don't think it is what you want, as it
will require some gearing.
What I found is that they are dependable, but not worth it for wind.
Anyway, either reply here, or send me an E-mail if you want it, and we will arrange it.
Just trying to save you some work.
