Everyone attempting to replicate this device, before you go any further you really need to ensure you have read this thread (below)  from start to finish (finish being a few day's after the video was released). There are many things mentioned on this thread that not all replicators appears to have picked up. height and distance of stators included.

Or easier to read this that has all the important points compiled into it

@ CLaNZeR

Is it possible that air flow through the rotor channels develops static charges?

Does the tape in your model need to block the channels, or can the tape be applied only to the area beneath the channels?

Hi Yardaraf

AL's did come up with the Static Theory and hence why I changed to HDPE but thenhe switched to the stray EMF theory.

I do not have open channels on my model as the picture belows, so does not effect it.

Must admit I had better results using the Polycarbonate and different stator magnets.
But testing is not over yet.

Cheers

@ Sean

Very nice video.  Great promise. 

Perserverence is not measured by the number of hours or days, but by the steady, patient tuning, of a man on a mission.  Thank you for showing continued diligence.   

Hi Bruce

And thx for your comments.

I have spent too much time on this and really should be getting back to work and paying the bills But hey everyone got to have a holiday sometime and what I have done, spent that holiday on this stuf LOL 

Hopefully after this weekend I will have my conclusion.

Cheers

Sean.

@ CLaNZeR

Much obliged, Sean.

I see now that your rotor is machined with a slight difference, and you'll be able to remove the excess if need be.  If you are successful with the "aerodynamic" rotor, then so much the better. 

Fantastic work BTW.  I envy you guys who have the fabrication facilities.

I have plans for a smaller system that includes computer control of rotor/stator spin-up and stator XYZ placement for automated tuning.  I'm not sure how far I will get, but your sore fingers would appreciate the approach.  I let computers optimize systems while I do other things.


Cheers,

Well enough of Sore fingers this end trying randon configs, so now I am happy with my Rotor and Stators, will start the boring task of altering Stator height and Air Gap.

Clanzer,

I can stop chuckling while watching your video.  Definitely the best video so far... well maybe second best, behind Al's. 

I do not envy what your finger has waiting for it this weekend.

It seems that there are too many variables at play here. Such as the separation of stator and rotor, diameter of rotor, phase angle, magnet strength, number of magnets on rotor/stator, RPM , heights etc etc.
Its next to impossible to get it working if you build it to some fixed specs(?), where there is not much room for experimenting. What is needed is a setup where you can vary as many parameters as possible without re-building the machine again and again. I started thinking of something like that and tried making a 3D model, which some may find useful and I encourage the experimentators here to build something similar.
Remember its not a machine, but an apparatus to experiment with. It may work at some magic combination of hundreds of possible combinations, or it may not.....

Here is a basic setup, with a rotor arm that is mounted on bearings on an axle and a stator arm that is on the same axle, and is rotatable as well as can be secured in position using a "key". You just tighten the key until it cannot be moved.

Both arms have "Sliders" (blocks that slide over the arm and can be secured with a key). The one on rotor arm has a "Magnet holder" which holds the rotor magnet in place. The stator arm has a "Rotating stator holder" whose function you can guess.

Below you can see how various parameters can be changed easily.
Changing the rotor dia, height and separation from stator.

Changing the phase.

Even a kinetica-toy-like (rotor and stator at 90 degree) or Perendev-like (angled rotor magnets) arrangement can be tried.
(http://img142.imageshack.us/img142/8333/perpective4bm8.jpg)

The above was basic setup with one arm each, just to show everything clearly. A practical setup would be like this...
With 8 rotor magnets and 3 stator rotating magnets, for example...

(http://img138.imageshack.us/img138/1524/perpective3sb4.jpg)

Now you get even more things to adjust, like various asymmetries and various rotor/stator magnet ratios etc.
The components are simple and same design repeats mostly, there are a few unique things on which you can built up.
Its not a weekend job, it may take years to find the correct combination. All you need to do is start varying each and every parameter and plot a graph for that combination. Some intelligent guesswork should help (or may be a dream like OC's :)LOL)
Best of luck finding the sweet spot.

Copied from the Steorn forum.

He told us he was sure it was not OU, and was due to a 17000 joule source of energy (a double-A battery?). The clues were all there, but we didn't tumble to the joke; instead, people spent time and money building replicas.

In that case, If I were in Al's shoes, I might be too embarrassed to admit the joke at this point.

Two NiMH AA batteries will deliver 18144 joules

Draw your own conclusions

Doh! hahahaha,,,
Well at least everyone has a rotating test bed of some sort.
How about ditching the magnets and trying an electrostatic coupling.

Oh yes, if you add stepper motors that are hooked to a PC, to vary everything automatically and precisely, in above apparatus, you can simply leave it running for a month and come back and print out the OU combination ready made for you..... 
Now this I call brute force....

Hi sharp & accurate (N)PMM builders and freaks!

Sorry for disturbing, just my 2c :

Are all these  N?PMM a matter of magic, serendipity, chance, patience or else? Are they reserved for PK (psychokinesis) gifted individuals?

A 83 years old retired engineer friend of mine has recently designed a self starting and self running (unfortunately  for just a little while =/= 3/4 hour )  permanent magnet device. He  insist that this thing must be very very accurately tuned (less than one milmeter). After that time you have to replace this ring shaped ferrite micro wave oven magnet.

BTW: I have been told that ferrite and 'neo' magnets were not 'friends' and that you must mot mingle them. was I been told right?

I have shown his very device. Guess what? He was not able to get it running! Anyway, I trust him.

A couple of years ago I purchased a LEVITRON. Me and my son were also not able to have it turning! However this LEVITRON is now an 'official' device. Of course we could be morons. 
I offered this (useless) LEVITRON my aged friend.
