STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

...The Steorn Orbo incurs no back-EMF (BEMF) on the input power. This fact alone proves that the device is overunity.

False statement.

False statement.

I spent hours of my time typing at my keyboard and explaining my position in detail, in many different ways, in my previous posts.  And now you utter two words, "False statement" and expect me to respond to that?

Yes, the absence of back EMF definitively proves that Orbo is overunity.  I have already written hundreds, if not thousands of words in previous posts to support my position. I will debate endlessly on this issue if necessary. So, would you care to explain why you feel it is a "False statement"?

Have you guys seen the latest S2Gen Episodes by JLN ? http://jnaudin.free.fr/2SGen/indexen.htm
For the first time I must say that his explanations and experiments are not right at all.
He says:
"The output coil must be fully EM decoupled from the input coil (no mutual inductance), so this is why the toroïdal coil is used as the input coil and a cylindrical or a flat coil set at 90° as the output coil."
If one coil is decoupled from the second one (toroid coil vs cylindrical one) why is he saying that magnetizing toroid coil directly affects the cylindrical one ??!

It is not the point. He is wrong because the toroidal coil is not at 90° from the output coil. This would be true only if the plane of the toroid was horizontal as the output coil. But we know that it doesn't work in this position. What is to be accounted for is the angle between the plane of each turn of the toroid coil and the plane of the output coil.

The output coil is horizontal and the toroidal coil is vertical. In the left and right vertical sections of the toroid coil, the plane of each wire turn is parallel to the plane of the output coil, thus they are coupled.
The idea that no field can escape a toroidal coil is false when the core permeability is not uniform. As the toroidal magnetic field inside the core opposes the permanent magnet field in one of the vertical section of the core, and adds in the other side, the permeability is not the same in the 2 sides, thus the flux is not balanced, it follows that field escapes leaving us with a direct coupling between the toroid coil and the output coil.

Isn't frictional loss just another load on the output torque?

I still don't believe that you really need magnetic bearings. Conventional bearings will cause some frictional loss, yes. However, that frictional loss pales in comparison to the load that you will want to place on the output -- whether that load is a generator, a lawnmower, or a vacuum cleaner.

The Orbo can output any strength of output energy that you wish, depending largely on the strength of the magnets. The only forces acting on the rotor magnets are accelerating forces. If the Orbo is designed correctly, there should be almost zero decelerating forces on the rotor magnets.

If you drive your car and only step on the gas pedal -- and you never step on the brake pedal -- and factoring out such things as air resistance, then your car would accelerate forever.

In an Orbo, where are the decelerating forces? If what you say is true -- that the magnets will not reach their next attraction point (by which I suppose you mean, the next toroidal coil), then there must be decelerating forces acting on the the rotor that counteract the accelerating force of the magnets being attracted to the toroidal core. But what are those decelerating forces? You can't claim that bearing friction would be a problem, because standard bearing friction is almost nothing compared to the accelerating force of the magnets being attracted to the toroidal core. In the event that the bearing friction is too high, such that it would stop the rotor, then either get a better bearing, or get stronger magnets, or spray WD40 on the existing bearing.

I would say that that is an understatement. For an understanding, see my recent posts.

Do a wind down test at 300 RPM with a rotor on the best conventional bearings you can find and do a comparison with the wind down test with magnetic bearings at 300 RPM.  We're talking about a couple of minutes at the most and will more than likely be under a minute with very good conventional bearings as compared to 20 - 30 minutes with magnetic bearings.  Conventional bearings create a huge mechanical drag on a rotor, rather you like it or not.  The more drag and friction in the system, the less RPM you will achieve.  I believe the vcr head has very good bearings.

The eOrbo is not OU at very low RPM's.  There is a certain RPM where it is at unity.  Increasing the RPM above this certain RPM increases the OU.  Without magnetic bearings and low air resistance you won't reach the RPM required to go above unity because the gap between the toroid and the magnets are huge which produces a very low torque.  Increasing the strength of the magnets mean you will need to increase the gap between the toroid and magnets in order for the magnetic interactions to be decoupled, which won't increase you're torque.

If magnetic bearings wasn't essential, then Clanzer wouldn't be using magnetic bearings in his replication.  Clanzer is a member of Steorn's SKDB,  http://www.youtube.com/user/Seacrhing2008#p/u/1/S9h30mAp_Uc

The only reason why the Orbo can achieve high RPM's with very little torque is because there is no BEMF, near 0 losses with the magnetic bearings, and low air resistance.  If the BEMF, losses from the bearings, losses from air resistance is greater than the very small torque, then it won't be able to accelerate and it won't run.  Even if the torque is slightly greater than the losses due to the conventional bearings doesn't mean it will obtain a high enough RPM to go above unity.  Slight vibrations and a slight wobble in the rotor can even interfere with eliminating the BEMF/CEMF, especially at higher RPM's.

If it does achieve an RPM that is above unity with conventional bearings, then it may not be able to maintain a RPM higher than unity after you add the generator coils.  Magnetic bearings are a must in the eOrbo.  No ifs, ands, or buts about it.

For an understanding, see your recent posts?  WTF.  I read every post here.  I do not skip posts.  Your understanding of things don't mean it's correct.

A good site hosted on youtube just got removed the authors were Magluvin and second Gotoluc.

Search on google their youtube channel still exists.  http://www.youtube.com/user/Magluvin

A long vortex coil coil with twin windings are shown and generate good result yet small unlike 2SGEN nicely made by Naudin.  http://jnaudin.free.fr/2SGen/indexen.htm
My idea would be to:

Using a one metre soft iron wire wound with a copper winding all along and then made into a spiral should become an ideal wall between two magnets and a coil to generate a variable magnetic field in a coil to generate current. passing a square wave at high frequeny will give great results like Naudin should work and setup will be cheap.
