    I don't know much on the subject of wind generators, but for those who want to play with it in an inexpensive manner, you might take a look at the Chispito plans.

    Undoubtedly not the most efficient wind generator, but cutting up a chunk of PVC pipe to make blades, and scavenging a tread mill motor for the generator, could certainly be cheap enough for the hobbyist.

    I've also seen a lot of hobbyist projects on the Instructables web site, but I highly question most of them. For instance, there is one who claims you can use an old cordless drill motor for the generator. Don't know how sound the proposal is, but in his particular case it appears he has a rollerblade bearing isolating the blades from the motor. Sure spins nice in his video, but I can't figure out how it could be spinning the 'generator' with that bearing in the mix.

    I often wondered whether you could attach an engine fan to the pulley of an alternator and then make a small rack that would hold it off the ground. Run some jumper wires to the battery and when the wind blew... This way you'd be carrying an extra engine cooling fan and alternator as well as getting some power when the wind is blowing. You'd have to turn it to match the wind and it probably wouldn't be as efficient as a dedicated set-up, but it would be spare parts as well.

    I can only imagine that a 100 Amp alternator needs a pretty good wind to generate much current
