Step 15: Test!
No time like the present. Blow on it, put it in the wind, attach magnets to the vertical piece of the frame and tack it up on a AC vent, hit with a Shop Vac blower (I've done this--it holds up just fine).
*apply more WD-40 if needed (note: a helpful commenter let me know that WD-40 is not a lubricant, but a solvent that has similiar properties--until it dries up. Use light weight oil instead, 5 to 10 weight)
*blowing on it will get you about .5 V DC with my set up. Hopefully you will get a lot more (it's those thin wire wraps that will do it for you)
*I had 1.12 volts with it sitting on a fairly gentle AC vent
*with the Shop Vac, it gets up to 6 V at least before it starts to rattle like crazy and pop out of the dimples. You will probably get even better results.
