The Gabriel Device, possible COP=8

@Feynman
I just did a cursory internet scan..didn't find any that had the right fit for the outer shell. Figure it was best to validate with the same cores first, but here's one that has also some large toroids for future reference:

I've been looking a bit more in detail how the device is suppose to work, and I don't believe this device works according to Thane's approach. To avoid the BEMF to the primary, Thane's approach was to move some of the magnetic flux from the secondary to a separate core (the secondary core). This requires that the secondary coil be wound over the 2 cores as pictured above. If you look at the Garbriel device, it is exactly the opposite; it is the primary core that encapsulates the 2 cores concentrically. According to Faraday's law, the magnetic flux from the secondary coil will impact and generate a BEMF in the primary coil since the primary coil turns are wrapped over the secondary core also.

If we were to apply Thane's approach to the toroid configuration, the primary and secondary coils would be switched (i.e. the primary on the inside toroid), and the higher permeability core on the outside also. In this way the outside secondary core would absorb most of the secondary flux and not impact on the interior primary coil to generate the BEMF.

Assuming we can replicate the results, it may be a lot tougher to explain how the device works, lol! If anyone sees something wrong in the analysis, let me know.

You make some great points... for me, the fact that Thane was in contact and was enthusiastic about David's device suggests to me maybe Thane has a deeper understanding than he did previously.

I think the first thing we need to do is bench this thing out to make sure we've actually got anomalous phenomenon. It's promising, but we don't have a replication yet.  If we can get a successful replication, then we can try to make theories to predict the anomaly. Because it's not science unless it can be replicated.  So that's why I've taken the plunge on the expense.

Since we're all going to be waiting a few weeks anyway for parts to arrive, it probably wouldn't hurt to speculate.  Assuming the Gabriel device is working as claimed, my 'explanation' for it would be that the primary somehow induces magnetic flux in the secondary (proportional to the rate of change in 'current'), with the back-EMF somehow trapped in the primary shell.  That's one vague idea.

Another related idea, in terms of the secondary magnetic flux inducing back-EMF into the primary, maybe this is stopped because the metal shell acts as a 'Faraday cage' of some sort, a sort of "one-way" mirror for magnetic flux. 

My last speculation to consider is that if properly done, the vast majority of magnetic flux in the secondary is going to stay inside the Nanoperm core, particularly in one of these high-permeability toroids  (besides the leakage flux). So again, perhaps it's the combination of the really high magnetic permeability of the core combined with the 'Faraday-cage' like properties of the steel shell.  How it works exactly I have no clue, but these are my thoughts at the moment anyway.

Let's keep our fingers crossed...

P.S. Also I think it's important also to factor in the material resistivity

Hi Wayne,

I'll have a look at his claims just to make sure.

I am not sure I understand the meaning of the primary core, the metal donut shell.
If I am correct this can be a plastic shell as well? Maybe even preferred....

Hi Tesla,
If it is a plastic shell, then it has no magnetic significance. Then it magnetically reduces to a standard toroid with 2 windings which wouldn't account for the power gain. It may take a while to figure how this thing works.

These look like they'd be useful for experiments, but not sure about the replication...

Hi Mavendex and all,

sorry if this has been mentioned already but it seems very crucial to me. About the primary donut, I've heard iron and steel, that's a BIG difference. Is this primary core magnetic material or not?

thanks,
