Check out this really cool DIY on how to make a vertical wind turbine. This thing can produce some good amount of electricity for under $300.
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.
