This device is the real self-running overunity?

[Airstriker]

Just wondering how many of the guys replicating this and reporting failure are actually using A bearings - none I bet!

Who has replicated this so far ? I haven't seen anybody.

Just use the "B" magnet configuration and don't use magnetic bearings. Magnetic bearings are not stable (at least not this type) so it's just stupid to use them. You're also missing one VERY important fact, that's even more crucial than minimizing lenz law effect here and this is why this design is so good and promising. Hope you will get it. If you do, I have some vidoes for you;>

Hej Airstriker,

Please do not tease us and tell that VERY important fact and also show those videos too.

Thanks,  Gyula

Hi Sprocket,

What Th3Generat0r shows with the Alu-magnet test is that the eddy current induced in the Alu (by the changing magnetic flux of the diametrically magnetized magnet) also creates a magnetic field that works against the magnet's flux, in fact fact repels it, hence a certain distance, a gap is created between the Alu and the magnet's body. So mechanical friction is none but there is 'magnetic' friction as you also noticed, which eventually slowly breaks the rotor's rotation.

There are better magnetic bearing solutions which do not use Alu or other nonmagnetic metals for keeping the distance but use other magnets instead in repel mode. Here are some videos on magnetic bearings, from the very simple towards the more involved:

The last video above shows the best case when the whole rotor levitates, as the case seems to be for Th3Generat0r too, and his inducing magnets also has magnetic bearings.

One  notice on magnetic bearings: because of the extremely small residual friction they have (even with eddy current breaks) it is very difficult to observe by the naked eye if the rotor starts decelerating in a certain setup or just keeps its speed or start slowly accelerating. So a dependable tacho meter for checking the RPM of the rotor is strongly recommended, otherwise the experimenter can easily "amaze" himself (and others) by making false conclusions.

@Gyulasun, great info, thanks!  What got me excited was the thought that although there would be some magnetic braking, the magnet surrounded by aluminium might outperform normal bearings by a wide margin.  It is a revelation (to  me) their would be no physical contact-induced losses with this set-up.  I managed to cobble together a very crude version of the German video at one time and while greatly impressed with the result, but I still had some physical friction from the axle (as does the German) - I hoped the aluminium would eliminate this...

In fact, all the videos you listed have this 'flaw', the requirement for a physical anchor to stabilise the rotor in the magnetic field!  In the Youtube messages of the last video, the creator of the magnetic bearing stated that there is some theorem that suggests that this is mandatory.  It's something I intend to experiment with nonetheless...

Yes, no true replication it seems, just elements of the idea...

@Athurs - excellent pic!  The wing-idea just doesn't ring true to me though.

@Airstriker: That's the problem, the inventor says it's not as easy as it looks, and now you are telling us too about a very important feature of it though not an obvious one. The thing is, if we try to replicate the device and we miss this feature, it is likely the attempt will fail.
