Hi All,

Let me put all this speculation to rest once and for all.

I recieved the plans after sending the inventor a copy of my drivers licence.  Sending any other lform of legal paperwork could lead to identity theft.

I will not and can not legally reveal any plan information.

Am I going to "waste my time and money" to construct it??

A big fat ---NO!! ---

Enough said-- case closed.


  I also want to thank all you guys about steering me onto ceramic bearings for my future projects. I now have a couple of open bearings on order.

Magnetman:

So is your reaction because he is vague on details, or is it that he displays signs of delusion?

His stated goals are at odds with not allowing those replicating it to reveal details, as indicated by his own words found here:

http://tech.groups.yahoo.com/group/mylow_magmo/message/2100

Where he states the following: "Only they must sign the agreement for disclosure by his sides too, to assure they not keep anything hidden or undisclosed. This is for all humanity use."

If it is "for all humanity to use", and he wishes to assure those replicating it "not keep anything hidden or undisclosed", then what the heck is this apparent prohibition on revealing details he sends to someone?

There is in evidence, and by his own admission lower on the above page link, a serious translation problem which clouds many details or aspects.

and lower on this above page he makes a series of extremely implausible claims on "variations" he's completed.  Saying he's fabricated "non circular bevel gears" is about as likely as the sun not coming up tomorrow!

Bevel gears or miter gears, have angled tooth faces to mate two shafts at right angles to each other.  Non circular bevel gears, if they exist would require 5 axis CNC to fabricate.  And the likelihood this chap has done that, is implausible in the extreme.

Could he mean non circular spur gears given his lack of command of English? (which are feasible and plausible to fabricate unlike non circular bevel gears)  Sure.... but those and Geneva mechanisms, and magnetic shielding are all completely different apparent operating principles than this "toy" in the video!

But all these "variations" and the serious number of inconsistencies, and dare I say even contradictions makes me suspect and less willing to give him the benefit of the doubt.

Almost sounds to me like he believes he has to save the world, and believes he has some ideas how to do so, but needs others to explore them....  Which might be a motivation to fake the video too if the [messianic] delusion were strong enough.

My problem with dismissing his stuff summarily, is there can be a way to make some of these methods produce a net gain!  I have bench evidence of certain kinds of magneto-mechanical coupling and feedback, of a non linear nature (both motion and magnetic force having non linear behavior) can and do make some net gain!

But finding the "sweet spots" are extremely tricky!  Think of it as a set of interrelated parameters, not unlike playing lottery number combinations.  If you have to pick 6 numbers/factors out of say 39 variables, then the odds of hitting that right combination are quite high!

But if the odds are reduced by limiting the variables or being pointed in the right direction, then actual trial and error is not so daunting as it is to blindly stab in the dark.

So my internal "flake detector" is ringing alarm bells on this chap.  But at the same time if he has found one or more "sweet spots" I'd like to explore them.

Can you indicate a bit more why you want to abandon things after reading his "plans"?  Is it because delusion appears at least in part at work?  Or is it simply that the variations he describes are way too complicated to afford, with no proof they'l work? (I believe he counsels not to replicate the video toy, but that one should try one of the later variations instead)

Or is it that details are too muddy with broken English and bad translation?

You could elucidate on why you're not proceeding without revealing details of the designs. (examples above:  of inconcistencies, evidence or inference of delusion, bad/missing details, etc.)

Vague on detailed information so you must make decisions on your own.  Thats not in keeping with a exact replication. Not covered-- What N grade magnets do I use??  N38, N42, N50?  Take your choice and your not in the ballpark any more.

[ellubpt]

I refrain from commenting. Learned my lesson.
What does that mean.?
Fool me once...........................
Consider this a DONE DEAL.

[wattsup]

The confidentiality agreement is to make sure you cannot say how much of a joke this is once you actually see or try the plans. lol

Mylow's sickness is becoming a pandemic. We should call it "Cerebral Mylowopathy".

A total waste of time. No more for me. We gave the guy the world of benefit of doubt and got shafted all the way. Now this other guy wants you to sign an agreement so you have to keep your mouth shut when you realize this is a dud. Probably his way of trapping some guys into potential litigation. Spread the net and catch the fish. He won't even have to prove in court that his device is real and he still will be able to sue you. What a world we live in.

OK, since I had already started down this road, I might as well finish it.  To my view, so far replications posted online are not faithful to the details in hand.

Namely proportions [mass and dimensions] are important, as are the actual materials he used.  Such as the hardened steel socket head cap screw as "shaft" and the 304 stainless rotor.

Turning and machining stainless is a pain - but it can be done.  You have to have enough "beef" in your machinery, and use slow speeds and feeds and copious cutting fluid/coolant, with sharp carbide inserts or tooling.

I've completed my rotor blank, and mounted a full ceramic bearing in the journal cut for it.

See here:

http://www.youtube.com/watch?v=TqviPQMFe7Q

And completed some reference friction tests via starting a timer at a given speed, and timing how long to come to a stop.  Forgive my verbal fumbling in the crude video, I did not write a script, just winged it.

Also shown in the video is that most of the time when obtaining 304 stainless, it is slightly magnetic, from being work hardened in manufacturing. (cold rolling or cold drawing).  And that there IS significant eddy current drag produced between rotor magnets and shaft, enhanced by shaft being steel and attracting the magnet flux to flow into an along the shaft.

Once I machine the rotor magnet's mounting holes and get them mounted, I will repeat these kinds of tests with and without stator magnets present.  (so some measure of what has happened to the net torque acting on system is obtained)

More when I get it done.
