Put a hand crank on it hook it up to a 12 volt battery and crank it. See if you
can crank it fast enough to charge the battery about 13volts or so .
If you can keep an eye on the second hand of a clock and count how many
turns you are spinning it.
If you can't spin it fast enough, repeat procedure with a 6 volt battery.
Now after you have determined how fast you have to spin it we can go
When you have got that now you can figure out a practical speed to
spin it , and what would be the most practical way to spin it, a VAWT
comes to mind for beginners .......where the generator can be on the ground
I'm suggesting that you start small
even if you are using a big
If you start small and fail , it's less of a heartbreak .
Hope this helps ......anyway get started and there will be plenty of us to
give you helpful
advice and suggestions.
Have Fun !
Norm.Let me know how fast you have to spin it , I'm dying of curiosity !
