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

I think you guys are putting way to much into this. 
Way to complicated.

That's pretty much exactly what I decided after watching these new demo's as to how he's getting rid of the back emf.  I also think he is being really picky with his magnets too.  They are measuring each one of their magnets with their gause guage, and making sure they align magnets in pairs with as close to identical fields as possible to cancel each other out properly.  I have also been trying to figure a good way to more focus the field of each magnet more directly in front of the magnet instead of so spread out.  This would make the inductance change happen in a more narrow width, thus decreasing the amount of time a pulse would have to be sustained, for the same results.  Maybe wrapping the magnets with thin metal sheet, so as to draw some the stray fields in closer.  Or orienting magnets inside the rotor sideways, point directly at 90 degrees the rotor magnets opposing them.  This should force the field of the rotor magnets to be more focused forward and tighter.  Not sure, still pondering on that one.

Just thinking a bit, you could add a balance coil to the torroid, detect the CEMF if balance wasn't perfect and add corrective negative feedback pulse bias to the core to make it perfect!!!!  only 3-4 turns and a summing junction in a op amp or high speed micro. Give or take.......Many ways to tame the beast.  Got to shut up now, talking too much...........

Or just wind two layers around the core, one layer clockwise and the other counter clockwise?
Balance it by adding or removing one loop on the last layer.

My impression to this video presentation is,
that Steorn is totally right with this.

Interesting to see was, that the toroidal coils gain in inductance,
when the magnets approach.
Can we get some testers verify this ?

I would have thought, that it would be the other way around,
but maybe they are switching their coils at different angles
as we would have thought of ?

Isn´t a ferrite core not getting saturated from the magnet and then the coil
around it having a lower inductance ?

Hmm,
have to rethink and ponder about this.

Here is a page with some good calculations for toroidal coils:

Well, does somebody know, what kind of coils Steorn used
in the other NORMAL pulse motor ?
Did they have just normal toroidal coils without a ferrite core ?
or were these ones cylindrical aircore coils ?

ALso Ben is right, with this setup one could build a great dragless
generator too wit the right coil setup and a highspeed motor powering the
Orbo-Generator.

Greetings all,
This YT video uploaded by Steorn tries to explain why people are having problems with replicating Orbo effect:

Hopefully it will prove to be useful for someone (TK?)
