Three things
I didn't make any previous statements in this thread.
My smart ass response was in response to your smart ass response.
As I pointed out a car generator and a wind driven turbine have two
completely different capabilities.

Yes, windpower has restrictions on useable power, rpm ranges etc. but:
" What happened to your acknowledgeable question?" Just guessin here
as that doesnt' really mean anything. You seem to think that my post
is incorrect
I am addressing your statement that a gen/alt requires a constant
speed to produce useable power. That is wrong. I pointed out two
different applications that do _not_ require constant speed. They
don't even need a constant speed to produce a "given voltage" as both
the automobile alternator and the old wincharger plug along pumping
out 12 volts (car) and 6 volts (wincharger) DC regardless of rpm.
I think you are confusing voltage with type of current. For AC
current you do need a constant speed generator/alternator.
The old, small, winchargers only had a 2 blade prop of around 6ft
diameter and were quite productive. Limited power output true but
enough for the purpose.

Yep, my bad. It was "Tim" tht made that statement.
As a "smart ass" reply, you failed in that what you posted wasn't even
in English much less having any meaning.

Go to a junk or antique store and take a close look at an old petal Singer
sewing machine. That will do what you want. Just build one to fit your
mill.
