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

Who said there was a link the said "MAGAMP" was nanocrystalline? I said it was, and I suggested that you contact Metglas to know. I gave you a page that's titled says nanocrystalline & amorphous, where MAGAMP was listed, but you seem to interpret that differently. That's all I can do for you.

The products that are nano-crystalline clearly says so, and MAGAMP does not say so.  MAGAMP and other non-crystalline products are being referred to as amorphous in the statement of "nano-crystalline & amorphous", while products such as Finemet, powerlite, and other nano-crystalline products is referring to the nanocrystalline part.

All I asked for was a link.  Don't get upset with me if it doesn't directly say MAGAMP is a nano-crystalline material.  If it doesn't say so, then it's more than likely not.

Wow, did you guys see the Steorn home page now?!  Look at the large flash intro!!! 

It says,

"This Saturday

My measurements already show that the Metglas MAGAMP core in the "tiny orbo replication" was ~ COP 2.  

Then why you don't have a self-runner yet.  What are you waiting for?  Your measurements can't be confirmed until it is self-running.  A self-runner is the ultimate test and measurement.

Why is there 100% resistance to the Finemet cores when there is plenty of research pointing to the Finemet as possibly being the core material in the Orbo.  The Metglas cores are accepted without question or any research pointing to it, except for it having the highest permeability.

Finemet is much softer than metglas, and page 8 of the Finemet brochure suggests this due to it's nano-crystalline structure.  I believe Steorn said they're using a very soft magnetic material.  He didn't say anything about having the highest permeable material.

On page 2 of the Finemet brochure, it says:

1) Satisfy both high saturation magnetic flux density and high permeability.  High saturation magnetic flux density comparable to Fe-based amorphous metal. High permeability comparable to Co-based amorphous metal.

You see, there is a difference between the amorphous metals, such as Metglas, and the nano-crystalline materials such as Finemet.  The brochure is comparing the Finemet with the amorphous metals.  Finemet has high saturation, high permeability comparable to metglas, and is a much softer material than metglas.

I'm going to sit on the sidelines for a while and let you guys figure this stuff out.  I'm tired of defending everything I say here.  I believe finemet is more promising than the metglas.  They both need to be tested and results compared.  It's that simple.

GB, I do not believe that is the case at all.  I, for one, do not accept just one or the other and believe the properties of both should be explored.  But, as stated before, my goal is not to replicate the Steorn demo devices (and NO that is not the sole purpose of this thread AS).  My goal is to learn about the properties of all the materials so that a design can be optimized for whatever end result is desired.  Since I believe that high rotor torque is desireable, I would tend to want to know what magnet strength is most highly attracted to what core material.  Others may be focused on the possibility of energy gain due to just the electrical input and the correct recovery circuit.

Point being, we do not yet know just what the "Orbo effect" is exactly, even though some are very confident that they have it all figured out.  So it is difficult to optimize any design.  So I wait patiently for more information, either from those experimenting and/or replicating, or from Steorn themselves.

I applaud all the useful information given here by all sources.  I also applaud those who do not join in the egostorms that arise from time to time.
