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

Hello ALL,

Here is my second idea.  I like it even better.  And it could also work with several rotors patterned  It incorporates Groundloops ideas also.

@ Fausto

I think there is still more to be revealed by Steorn in their upcoming public experiments.  Besides their public demonstration motor running on 1 D cell, recharging itself.  Pretty good proof for me.  Besides, this thing will be running all kinds of things, and some will still deny it...LOL 

Personally I am thrilled with the "simplicity" of it.  Complex, yes, but simple still.

Happy New Year!

For my small tu'penny worth, I don't think Steorn have shown all their cards yet. The 'brief' week before christmas demo was a teaser.
Anybody know when they are back? Is it Monday the 4th?

So, does using a lower Permeability ferrite core material have any potential negative effects for an eOrbo set up?

@mondrasek
If the core saturates, then magnetic flux will 'leak' out of the core material.  I think having stray mag-flds outside the core is probably not wanted in this application.

This video seams to be tapping my option 2 above where one could utilize the free spin energy to generate free extra energy without Lens effects on the knetic motion of the rotor (http://www.youtube.com/watch?v=SHH2j8kVjWE).

Exactly.  So, what is optimal for any given permanent magnet? 

Here is a specific example.  Let's say you have a 10mm diameter x 10mm long cylindrical magnet that will "hold" with a force of 100N if on a smooth surface of a steel block that is thick enough and has a surface area large enough to satisfy all needs for "attractive" target material.  Now if we replace that steel block with something with less permeability, say 50% that of steel, will the permanent magnet only hold at 50% the force, ie. 50N?  If not, at what decreasing level of permeability will the permanent magnet no longer be able to maintain 100N of attractive force?

Likewise, will the attractive force increase to greater than 100N if the permeability of the target material also increases over that of steel?

Hi all,

I am trying to figure this out too, and my brain is red hot right now:)  Have some thoughts about it. Here is my logic.
First, force acting between two magnetic poles is proportional to "magnetic strength" of those two poles and inversely proportional to distance square. Assume distance is constant. "Magnetic strength" is proportional to magnetic induction B (parameter which often describe permanent magnet strength), so to have maximum force the best is to have both magnetic fields strong. When ferromagnet is in magnetic field of permanent magnet, it tends to behave as another permanent magnet (induces field in ferromagnet) and attract each other. Induced field depends on external magnetic field H and is proportional to magnetic permeability of ferromagnet. So higher permeability -> higher force.
Now question about appropriate material for orbos core. Hmm, when I look on B-H curve, I would have material which first of all will need small energy to saturate it (low H - lower electrical energy to saturate, as well to desaturate). Second, material with high induction B (high B - higher force). In this case B-H curve should be narrow and rectangular (http://www.metglas.com/products/page5_1_6_2.htm). Unfortunately I can not yet find how magnetic viscosity relates to B and H (probably when material has low H, viscosity is smaller? and I am not sure if we want small viscosity).

I hope, I helped a little bit:)

Happy New Year to all
