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

[Airstriker]

Mumetal is not able to handle fast switching without significant losses as far as I am informed correctly.

Sure, so why not use a magnetic viscosity effect ? Why do you think Sean have some patents on it ?

Naudin has posted a new coil test on inductance of his latest rig.
http://www.youtube.com/watch?v=ww-F5MfWSGA&feature=sub

He shows also quite high values in Henries near 1 H.
As far as he indicated he uses ferrite as coil material.

In my view Steorn just uses simple ferrite cores.
Ferrite is able to handle high frequencies and has a permeability of around 4000.
Mumetal is not able to handle fast switching without significant losses as far as I am informed correctly.

Where does he indicate he used ferrite as the core material?  He doesn't say in the video or in the description of the video what he used as a core material.  It's not in the comments either, because there are no comments at this time.  You may be right though.

Something about that video doesn't look right to me.

..........................So all in all how ORBO really works ?:

- saturate the core with the smallest current possible at the right time (which is when the magnet meets toroid coil) - this is the only way that you end up with no back EMF
- use mumetal (SOFTMAG 78 Series) as the core material - hight permeability | low saturation point
- release the current at the right time (when the magnet is at the max distance from the toroid and so the Inductance is maximum)
- what you have at this moment is a gain in magnetic field energy which you utilize due to the colapse of the field (gratis electrical energy)
- you have a moving motor which enables you to make other (next) interactions for free (gratis kinetical energy)

Now what you can do more is:
- use the kinetical energy to do work (ordinary generator at the top disk of ORBO) - just make sure that it doesn't make the motor decrease it's speed - motor RPM must stay constant - remember what the tachoman was doing ?
- use low friction bearings to get more RPMs
- make the interaction gaps the lowest possible
- close the magnetic loop where the interaction is taking place (remember the two magnets in the original ORBO?)
- other stuff ?[/b]


Man... I just didn't realize it's so perfect !!!!!!!

@Airstriker I like your thinking on this. Nice touch adding the math. Change in inductance rather then change in current to pull more energy out than the electrical energy in.

Where do you believe the excess energy is coming from (2nd law)?
Is there a transfer from the neo's on the rotor (allbeit very small, motor would run a long time)?
Therefore Will the rotor neo's ultimately be depleted?

What are your thoughts?

As long as he hasn't revealed the materials, it's guess work.
The fact that he has a patent on magnetic viscosity doesn't prove he applied them in the Orbo.

I based my observations on his first setup:
http://jnaudin.free.fr/steorn/html/steornv1en.htm
He stated:

I used 2 ferrite toroidal cores made by Philips (purple color), reference 4C65-RK190. Outer diameter: 23.6 mm, inner diameter: 13.4 mm, height: 7.6mm. Permeability: 120, specific inductance Al = 87.
