Hi all, I have made many, many variations of pvc blades and have even written a set of plans with templates on how to make them. I intend to try to get a few ...

OK folks, discussion of free energy machines is off topic for this list --sorry I didn't pick up on it quicker. Further discussion of the Lutec machine should...
Hugh, ... It does make sense to count pulses. You almost have to in order to resolve the wind speed. That's what I'm doing. I don't see why it would be an...

Yes Phil, but how do you know the wind speed at which to set the magnitizing current or uf you have a PM alternator, how do you know what the output voltage ...
