Howard Johnson Replication Tube Claim

[PaulLowrance]

If mylow's alnico PM's are not draining, and it's only the hard steel stator's that are draining, then it's difficult to see how the energy contained in the hard steel stator is enough to spin that machine for 27 hours, but you never know.

*If* there's "free energy" in his machine, then I have a good idea how it could occur. See the attached chart. This chart was not calculated, but only serves as an exaggerated illustration. The vertical parameter is the magnetic field, and horizontal is time. This is the field strength of the stator PM. You'll see 7 dips per cycle. Each dip is when an alnico rotor PM passes by the stator PM. With each pass, the stator PM weakens. After the 7th PM, there's a period where the stator PM can rest. During this rest period, the stator PM would slightly recover-- a form of magnetic viscosity.

I've seen this long term magnetic viscosity in soft ferrite, and even more so in powdered iron. I'd imagine it's even more pronounced in some PM's.

My suggestion for mylow is to place further spacing between each rotor PM. Also, he might try to move the stator PM farther away from the rotor PM's. All of this would of course result in less power, so the machine would spin slower, but it could give the PM's more time to recover-- more free energy. If given enough time, then perhaps the PM's would last almost forever. I have an idea how to perhaps significantly increase the power and extend the lifespan of the PM's to almost indefinitely.

If anyone succeeds in replicating mylow's machine, then you may want to consider the following possible improvement by inserting a stator NdFeB PM in the stator hard steel PM. See attached images.

The goal is to keep the stator NdFeB appreciably away from the effect that occurs between hard steel and rotor PM's, but to give the stator NdFeB time to maintain the hard steels remanence. I would replace the alnico's with either ceramic, or better yet ***bonded*** NdFeB PM's.  It's difficult to give any further details, but as far as the NdFeB that's between the hard steel, it would probably have to be very thin.

This would probably be somewhat difficult to get just right. If the stator NdFeB PM is too think, then it could cause the hard steel to recover too fast, and thus eliminate most of the long/slow term viscosity effect. If it's too thin, then it's not going to recover the hard steel fast enough.

Only thoughts. These ideas have not been verified in FEMM or experiments.

For those who've seen the mylow new video of the stator field using a compass, here's a comparison of the one I did in FEMM. Maybe I have the FEMM fields oriented wrong. It seems to be in agreement. See attached images. This FEMM file was created yesterday before I saw mylow's video, and there was no tweaking to get it to look like mylow's.

In the attached image showing the *diagram* (not the field image), you can see the field orientation on the ends of the PM is directly down, but if you understand how the fields sum from all the ferromagnetic moments, then you'll know the net field will bend *outward at an angle* as shown in mylow's video, and also seen in the attached image of the stator field. The image of the stator magnetic field, you can see the edges of the PM do indeed bend outward at an angle as seen in mylow's video. I'm certain there will be subtle differences between the FEMM & mylow's stator PM since who knows exactly how it was magnetized and the type of alnico mylow has.

I spoke with Mylow this morning.

He is pleased to see so many people trying to replicate this.  However, he wishes to point out that they are not following close enough.

Some of the important aspects to include, as he sees it, are:
- the gaps between each magnet and the gaps between sets of magnets (fairly large [nearly 1/2 of the distance covered by the magnet sets])
- one non-uniform magnet set (e.g. all are 3&3, with just one that is 3&4)
- aluminum wheel
- polarity orientation of magnets

As he sees it, there are a couple of differences between his motor and the photo he saw of Johnson's Stonehenge motor are:
- his magnets are very weak
- his stator magnet doesn't physically come to a point (but the compass shows that the magnetic field is focused at the outside corners, in keeping with Johnson's principle).

I would add that the one imbalanced 3&4 magnet set, versus the remainder being 3&3 is probably another difference.  I've not seen the Stonehenge photo of which he talks.  He said he would try and send that.  He said: "All I did is look at the photograph and Bingo."  He saw the same thing in Howard Johnson's motor: sets of 3 or four magnets, then a gap.

The diagram he posted the other day turns out to be incorrect when it comes to the channel alnico magnets.  The compass video he just uploaded http://www.youtube.com/watch?v=ji5QUhI1IQE shows that they are similar to the stator crescent magnets.  He said the orientation of the rotor magnets around the perimeter of the rotor wheel is "North up".  Before he realized the true polarity via the compass, he used a bar magnet to make sure all the magnets were of the same polarity when he installed them.  After he had them on, he went around the wheel with the bar magnet in repulse mode to double check that they were all on in the same polarity.

He said that when he places the compass inside the rotor while the motor is spinning, it goes crazy, jumping (turning) all over the place.

He said that when he only had part of the magnet sets installed, he saw the same thing as is shown in one of the replications videos: the rotor would spin along the magnets until it came to the end of them, at which point it would bounce back.

Mylow thinks that the eddy currents being generated in the aluminum by the magnets passing by it could be an important component of why this works.  He said the all-aluminum (including the screws) stator holder that he made works better than the previous one that had wooden support legs.  He also thinks the concentration of the magnetic field in his stator magnet near the two outside tips (90-degree ends of the crescent) are an important factor for the function of this motor, in keeping with Johnson's design.

He things that these eddy currents may be contributing to the rapid demagnetization of his iron magnets, which I would agree is likely.  He also thinks that the demagnetization may be where the energy is coming from to produce motion.  I don't think so.  Based on other things I've seen, I would predict that a permanent magnet would not diminish but would work continuously (with a 100-year half-life?).  From what I hear, iron magnets are easily demagnetized, and the eddy current would probably accelerate that.

One little thing he added to his story of when he first saw rotation.  He said he scrapped the magnets off and reinstalled them three times to make sure he could replicate the effect.
