Just taket the rotor out of the alternator, keep the shaft, and place magnets, so they fly very close to, but not touching, the windings of the outer housing.

Beyond what I would try in my kitchen.

Keep the rectifer package, it converts the AC to DC for battery charging.

Here's a sales site, with photos of the innards

have ideas, scoraigwind.com has, somewhere, a .pdf of the OLD plan book, that may answer your questions

http://www.otherpower.com/otherpower_wind_alternators.html excerpt:
A normal AC induction motor can be converted into a permanent magnet alternator at very low cost. Our experiments have shown that these conversions produce significant power at very low speeds, but become inefficient quickly at higher power levels.
An induction motor has a center core with no wires in it, just alternating plates of aluminum and steel (it will look smooth from the outside). If you rout a groove in this center core to accept permanent magnets, the unit becomes a permanent magnet alternator! We sell super-powerful neodymium magnets that are shaped and polarized perfectly for this application--check our products page.

Or write to this guy http://www.dualrotor.com/ about 3/4 down is a converted car alternator.
