I'm posting this comment By "Harvey" at Energetic,
Because He has done some research on why this could work [the last part of this comment]

Quote:

Too bad the battery holders . . . I mean upright supports are not transparent

Sadly, they are large enough to not only house a battery stack but also a motor to drive the axle. All that is needed in that regard is the energy addition necessary to lift the stator magnet out of the conservative loop.

Because the cam would provide a gravity assist in normal conditions, it would have been good to see the device at rest with the cam down. If it truly worked as shown, without any momentum, it would settle calmly to a minimum point of gravitational potential energy balance with the magnetic fields. But if the rotor was driven by a motor, it would not come to rest in this way, but would begin bobbing as it tries to lift the cam against the gravitational minimum and finds its resonant position.

Since these two conditions are avoided (transparent supports, natural state of rest) the video is suspect.

That being said, I have shown with my M.A.P. tests that energy can be extracted from these two conservative fields when they are separated properly into non conservative parts. This device may exhibit such a separation. In my tests, mathematical projections showed there was approximately 10x the energy available for extraction than was required to drive the trigger mechanism. So while the output energy was minuscule, it was cumulative.

Why has Roobert33 removed the video?

From what I can tell, he is not wearing a wristwatch. Also, if he was, it should have also affected the RPM when he was moving the unit around, but it did not appear to.

Careful observation seems to indicate that the RPM throughout is somewhat erratic.

The device looks simple to replicate, why don't we try it first before we conclude.  ;D

for the truth will set you free. John 4:26

Beautiful! Fake but beautiful..! Ideal for Xmas!
It looks like a pulse motor: I bet the magnet below IS NOT a magnet, otherwise its movement is totally unexplainable. If it was a real magnet its movement would SLOW DOWN and NOT accelerated the wheel, so....fake, but beautiful

I'd like to see this running inside a bell jar (or plastic enclosure), on an open frame so we can see underneath it -- and running for at least 10 min.

rapid acceleration at the beggining + rapid stop at the end = fake = waste of time

10 min are the limit for youtube, isn't it? Anyway, I think your request will never be met ::) People has been asking for such setups many times, but no new videos... They removes the original videos, rather than displaying the truth.

I'm looking forward to any replications that will prove/disprove this design. The video doesn't rule out the possibility of the rotation coming from blowing air.

I've created a page about this over at http://peswiki.com/index.php/Directory:_Mechanical_Opener_for_V-Gate_Magnet_Motor

and I've made an animation gif.

Hey Everyone,

Just a quick observation in case you missed it. If you look closely at the 'magnets' that he has in the V track, you'll notice that the ends appear to be faced off (as in turned on a lathe to create a smooth finish). This seems to imply that the track is not actually made up of magnets (Neos would actually have a smooth, mirror finish on the ends, not a machined look). These are probably slugs of magnetic steel used to attract to the magnet on the moving arm.

In my opinion, the data presented thus far support no conclusions at this time.  Having said that, I too see some things that really bother me about this video.  I believe all, if not most of them, have been mentioned in the above posts so, no use repeating them.

The first one that always gets my attention is the stupid music that we have heard on many such videos.  If I had built this and it really worked, I would want the folks to hear the smooth action and the clicking of the mechanisms and also to know there was no air supply running it.

The way the fellow exactly positions the device several times looks a little funny also.  The device is in the shot but yet, it has to be moved just right before the demo.

Anyway, a lot to think about but, I am leaning toward the side of it not being a real device at this time.

Hi Jason -- good observation.

Hi Jason -- good observation.

I agree the magnets on the rotor look a little suspect from the video.   They may really be chrome plated plastic to keep the cost down.  With only the bottom or top stator magnets really involved to move the rotor.  The inside center of the rotor could have a pulsed coil and battery.   (hope the battery is not to hard to change and lasts)

Nice work... great kit.  Where can I buy one of these?   I looks like it is near production quality.   
It would be a great desktop kinetic energy toy..
 
Just think the moving sticks  in Ironman cost over $200.   
This could sell for almost as much if made more real.  However it is still a great toy invention.

Well well well.
Since we know that standard every-day physics -- the kind that explains how your Prius hybrid works -- tells us that permanent magnet-only motors cannot work by themselves, the default position MUST be that the device and the claims of self-running are not for real, UNTIL someone actually shows unequivocally that it does run itself. And roobert isn't  going to be showing us anything like that.
Replicators will be having fun with this one. I can only encourage the builders to do the correct control experiments along the way. There will be a time when you've got a completed assembly and you are trying various things to get it to self-sustain. So rig up a way to give the rotor a repeatable starting spin -- perhaps using a weight and a string and a pulley like I showed with MyLOW -- and then compare rundown times for your device WITH and WITHOUT the critical stator magnet in place. Substitute a non-magnetic weight for it and use a stopwatch, get an average of ten or twenty runs in each condition.
If you EVER get a configuration that runs longer with the stator magnet in place, rather than an inert weight....please let me know ASAP so I can open the financial floodgates for you.

TK:

I agree with you.  I always "hope" that one of these is real and then want to replicate it but, this one has quite a few irregularities from the get go and more observations are still coming in.  At least, I don't see any fish line in this one, ha ha.

Man, will we ever forget that?
