Well, you could use an automotive alternator for a wind turbine, in
fact it's not a bad idea, I have seen several.  A cheap solution for a
DIY project.
But you're right, these crackpot(s) wouldn't be capable.

 Harry,


This idea that an automotive alternator has any value in the hands of
the general public for a wind-turbine is just plain bogus. Wayne's
statement "That requires a rotor >20' in diameter. Are you trying to
say that you can hang that on a car alternator?" is a valid concept.

The OtherPower people who are flown hundreds of hand built
wind-turbines use 1000Lb. trailer axles to their home-built 10'
wind-turbine and 6000Lb. trailer axles to their home-built 20'
wind-turbine. If you try to hang even a 10' blades directly on an
automotive alternator's shaft the centrifugal and gyroscopic forces
would cause that alternator to self-destruct in a very short time.
Wind gyrates all over the place and you need a blade shaft that is
designed to handle these wild forces, alternators are designed for
steady rotational forces only.

Next you run into the issue of RPM, normal wind might generate 1000
RPMs with prop designed for high RPM, automotive alternators require
way more 1000 RPM to power with any efficiency. Now you could cure all
this with a separate prop shaft, bearing, and then gearing the mess up
for the alternator, but all that costs money and efficiency.

Lastly, you have to look at net power output, an automotive alternator
is draining the battery for field excitement as it's charging your
battery. Gross (charging) output - field excitement = net output.

 Understanding automotive alternators is not near enough, someone also
has to understand wind-turbines, if someone can get this idea to fly
in wind and is willing to post data, I'll give them benefit of the
doubt if their data holds and they're trying to sell this plan to
others, but until then selling this idea is nothing more than scam
designed to steal people's money.

BTW, I'm hurt that wasn't voted "Most Ignorant" maybe this post will
help?


When you're Right, you are Right.
