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

[Larskro]

HI
Use this calculator.

Hmmm...
Orientation of the toroid looks different than the one(s) shown at the latest demo.
Demo's coil(s) look to be horizontal and parallel to the rotor plane of rotation.
Coils may appear the same, but in the pic above the different realtive positioning to the passing rotor magnets may drastically effect coil's response.
If, and that's a big if, this is the orientation on the regular pulse A, and the Orbo has its coils flat, then we cannot be sure if these two systems can even be compared.
Thanks
Mike

Now that's it's proven Steorn uses ultra high permeability core, and IMO most likely the Metglas 2714A, their claim of excess energy seems even more believable.

The amount of energy required to saturate that core even in the presence of the magnet is almost nothing.

I would bet the farm that the Metglas 2714A core would show exactly what's seen in the Steorn scopes. There would be no hump when the magnet flies by because that 2714A core would be so freaking saturated.

Any legit researchers out there, here's where I bought my Metglas cores -->

Elna Magnetics

They stock a lot of Metglas cores.

The particular Metglas core that matches the Steorn measurements is the MAGAMP Square Loop:

Here are the Metglas MAGAMP cores I've had for years:
MP1805P4AS
MP1603MV3T
MP1303P4AS
MP1005M4AS

My largest MAGAMP, MP1805P4AS, is 0.82" OD, which appears to be a bit smaller than Steorn's, but still very close.

Hi Paul,

Do you remember what those cores cost in lots of 10?

Ben, they are very reasonable. Let me take a look in my email. ...  Attached image is a copy of my order. Black part I did because it contains my home address & phone #.

I believe the price is per item. So the MP1805P4AS costs $2.65 each. As far as quantity of 10, I don't know, but I'm certain they offer quantity discounts.
