I am one of the many people that think the old water
windmill on the open prairie is a beautiful site. The more I
looked at my blades the more I could picture a beautiful wind
generator in the air with the traditional look of yesteryear.
So after lots of testing for the dreaded multiple
centers of gravity which plagues most any even numbered rotor out
there and brings the death to many home built generators, I found I
must eat my words spoken about my Quadraflex AL.
It would seem that my offset design in the hub arms and blades has more
than taken care of the multiple centers of gravity issue, thus I now
release this design with a mouth full of crow.
This rotor is one powerhouse in the air and it is smooth running
beyond anything you could imagine. You can gear this one up
for even more output. Although it has a much lower top end
speed of around 800 rpm it hits it and holds it even under a heavy
We had winds here between 6 to 15 mph so I ran the
Power Disc AL on my 4 to 1 gear head I have with the Boss99.
It took 12 mph to start it, but at 12 mph it started and picked up
good speed and was producing around 300 watts of power. One
thing you should know is it take a pair of pliers to even turn this
4 to 1 with the Boss99. That should give you an idea of torque
this rotor produces.
Max output observed was 750 watts at around 14 mph. All the
wind we had at the time. It continued to produce 12 volt
charge all the way down to 7 mph.
This rotor could do up to 6 to 1 gear up on the
Ametek 30 or 40 basically tripling your output in winds less than 12
On the Ametek 50, 1 amp no load motor you could go at least 4 to 1
and have around 500 watts at around 12 mph. I am figuring 10
mph but playing it safe saying 12.
The Power Disc AL has a rotational start speed of 3.2 mph on an
Ametek 40 and has
rotational torque to produce usable energy at 4 mph for a gear up of
2 to 1, it goes up from there.
The Power Disc AL is 68" (5' 8") in
diameter and weighs about8 .0 pounds assembled.
