1 - There's a couple options in terms of alternators / generators. Hoverboard wheels are good in terms of cost and availability (in Western countries at least) and do a decent job tho will need to be geared up with a belt or similar to produce 12V charge voltage in realistic winds. Direct drive washing machine motors are usually high enough voltage to direct drive, tho can be a little tricky to source. Motorbike alternators will usually do a sufficient enough job, and are highly available in most parts of the world. 2 - The electrical side of things, ie charge control, batteries, load diversion, inversion, etc really needs to be tailored to each individual situation. We've got this Facbook group going: https://upload.facebook.com/groups/windturbinemakers/ https://upload.facebook.com/groups/windturbinemakers/ for figuring out that side of things and others.
