I am looking for plans for a small diameter windmill that will charge a couple of 12v marine batteries. 12" blades would be great with a 20w output.
Does anybody have a DIY material list and plan available?

Try looking here at ed's site it will give you ideas,

I suspect a small permanet magnet(PM) motor would be best for your purpose, the chalenge is to find one that is not rated too fast. Remenber voltage is linear to speed on PM motors.
