TD replications

Luc,

How can the 16.125 inches of pull data that you collected be 180 degrees?

Since it can not be 180 degrees then the illustrations that were added can not be correct.  They should then have the rotor magnet at 45 degrees to the slide magnet, then rotate 45 degrees (8.125 inches of pull) so they are now in the output position and the slide released, then the slide is held and the rotor is turned another 45 degrees (8 inches of pull) thus covering the 90 degrees of pull distance you measured.

Now if the 16.125 inches of pull took the rotor magnets from 90 degrees to the slide magnets and placed them in the output position and then the slide was released and then you pulled another 16.125 inches for the next 90 degrees of rotor rotation and if that had the same force measurements as the first 16.125 inches of pull,, THEN your assumption is correct

This is where I am confused.

That's where the error was. It never was 16.25 inches!!!... it was twice that!, being 32.5 inches.
Do you understand now?

I have 129 steps times 0.125 = 16.125

Yes, I see your point. I'm going to go over it all to see how that part could of happened but maybe it's as simple as the 129 samples were taken every .25 inches and I thought it was .125 inches?

I'll go over it to try to figure it out but for sure there's no error with 129 samples for 180 degrees.

I looked over my original papers and I can confirm the 129 samples were taken every .25 inches. It was the output sample that were taken every .125 inches.

Hope this satisfies your concerns

Bonjour Laurent,

You may want to test Floor's recent suggestion of magnet shielding: http://overunity.com/17097/magnet-force-shield/msg502025/#msg502025

Floor's video demo: http://overunity.com/17097/magnet-force-shield/msg502025/#msg502025

Kind regards

Hi Luc

Yes i have tried the Floor's config.

So first, yes the shielding magnet seems to slide easily through the first stuck of magnet, but at the expense of a strong up or down force (in fact this is the slider's stroke force of your V2 version), so this up or down force (depending of the vertical orientation  of the stack of magnets) should be strongly directed with very good build and efficient sliding gear to maintain the magnet on the path and avoid too much friction losses. And so to be able to precisely measure the engage and disengage energy. By hand due to all the mixing forces it is of course impossible to correctly estimate .

The second thing i notice, is that the shielding effect seems to be some how effective when the second (moving "piston"  ) magnet is very near to the shielding magnet, but at some distance, some repelling force is always present.
So there is not a  complete cancellation of the repelling force , anyway with my magnets crude manual  test and ,another time, by hand it is not possible to really estimate, due to all the mixing forces.
So it seems that we  always need some mechanical force to approach the "piston" magnet towards the shielding magnets. Adding that this "piston " magnet exhibit also strong torque and up and down forces, that have to be correctly directed by a efficient  mechanical device to maintain the path.

I tried to double the thickness of the shielding magnet, but all the above stay more or less the same.

So to be able to test properly , we need to invest time and energy for a very well and sturdy build, with very fine scale and a lot of time to detect if there is any OU possibility.

But by doing those crude manual test, i am sorry to say that i did not get the "waouuuhhh" feeling, that could motivate me to go further on this delicate experiment.

So to me, all those systems are very effective and interesting magnetic coupling device , but so far no OU. But i can be and i hope to be wrong of course.

Perhaps Floor will elaborate more and find the right path to the Graal.

Hope this helps

Thank you Laurent for sharing your preliminary shielding test.

One thing for sure is, if there's a magnet configuration that can go thru a complete cycle an have a gain it's still unknown.

I'll be keeping an eye on floor's research.

Kind regards
