I was interested to hear that you never had any sucess with the neo's. What type and size magnets are you using. I was about to order some neo magnets when I read your post.
I was also interested that the device runs in a notchy way rather than a smooth rotation. Is this correct or am i mis reading something?
Finally, how much forc does it take to get working.
Kind Regards

Sm0ky2;

I have done some analysis of how this wheel works and it appears it
actually will. I don't see how nature is going to manage long
term "conservation of energy" if this is built correctly.

There is three worries, I have. One is to use aluminum metal backing
for the array because ferrous metal can be "written on" by
an external field. (this may be why the wheel needs to be left
"sit" between times it is working.) So use Aluminum. And
two, I'm worried that somehow wood's tensile mechanical strength
may be being "used up" to supply energy. So in general, no wood
in the wheel and no structural bulk metal in the arms or the wheel.
The third thing is this neo magnet problem, I think I understand
that one can extract energy from non-neo "erasable" magnets.

A Target Design

Here is a target design that you may be able to work towards.
It doesn't need to be done all at once. A semi-working wheel
is much better for this than a cold start up design.;

Make the wheel from a machined ceramic plate, from the material they
make HV electrical insulators from. They also build ceramic printed
circuit boards from this stuff. It's a little tough to machine, I hear,
but doable.

Put six brass studs around near the periphery of wheel and solder a
copper washer or wire loops at the top of each to make the guide
yokes.

For the arms, use one Teflon plastic dowel and maybe two carbon
fiber composite spokes for a bicycle wheel or similar. The outside
arms could be carbon fiber and the center one the Teflon dowel.

Epoxy Puck cylinderical magnets to the ends of the arms and
apply a wire loop with glue to the arms as motion "stops".

This would make something that is stiff, non-conductive, light,
moves smoothly and has it's weight and mag fields all near the end
of the arms. And would have thermal dimensional stability unlike
Lucite. Strong Neo magnets reject external magfields. What's a Lenz
Law to grab onto and screw up? Short term wear shouldn't be a
problem, and arm twist would not be a problem because of the
symmetrical arm layout. It wouldn't need the complexity of ball
bearings in the arm slide yokes at first.

If you can get something like this to work reliably, you demonstratively
will have solved the energy crisis. There will be no final design but
just a reliable intermediate one.

@Smoky2:

I'm not really up on this thread or your design, so this may not be of much help.  Here's a video using Rolamite for a linear slide, http://www.youtube.com/watch?v=O-1Drlfuoi4

Wiki has additional information on the Rolamite.  These devices use a stressed metal band and counter rotating rollers within an enclosure to create a linear bearing device that loses very little energy to friction.  http://en.wikipedia.org/wiki/Rolamite

It's just a thought that could possibly be incorporated into later designs or builds.  I look forward to your video.

Thanks,

GB

@Mark

I'm concerned about this magnet thing too. I hear that the longer
the pole/pole distance of magnet the further it's field extends. Archer
Quinn mentioned the fact that short pole to pole magnet distances
were not of much use generally.

Also, please don't contaminate your OU projects with non-Neodymium
magnets. I strongly suspect these will work but for the wrong reasons.

The "latching" strength of the unbalanced arm of this wheel
locks an arm into position by centrifugal force, so the more RPM
the stronger the latch, but it then takes more magnetic strength
to pull the arm out. Sounds like possibly a job for a dynamic RPM
vs distance feedback mechanism actually, but first things first.

That Rolomite bearing is interesting and I am glad you brought
it up. I suspect that some friction isn't the problem but arm
wobbling that lets magnetic forces convert themselves into
wheel momentum dissipation losses that is a problem. One really
wants those forces to stay in their own motion dimensions.
