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 500 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 2x4 X 12' studs (from lumber store)$11
I am not going to name the tools, but I used the usual tools.
Step 1: PVC pipe
2-Using a template, to where I want the hole so the pipe did not travel past the rim, I simply drilled the hole (as shown in the photos)
3-I laid the 1/2 pipes down alternating ends. We all know that the pvc has one end wider than the other to be able to fit to each other (phlange)
That was it for the pvc..really ...that was.
