With this one I am hoping to get the 100 watts. Here is how I did it. First we need: –5 pvc tube. size 3″X10′ (hardware store)$48 –3 bike wheels. size 12″ (junk yard or ask your kid to use their bikes for a minute) maybe $5 –Ametek38 volt (ebay or surplus store) $60 (a problem with ametek, it needs 700 rpm to reach 14.1volt. –Or buy windblue alternator (ebay) $250 it will only need 200prm to reach 14.1 volt –1 square foot 1″ plywood or anything 12″ diameter (laying around) — 3 X 2×4 X 12′ studs (from lumber store)$11 I am not going to name the tools, but I used the usual tools. faroun via hackaday, instructables Recommended “Wind Turbine” books on Amazon
