The Gabriel Device, possible COP=8

@Import: I'm curious to know how you sliced that donut so perfectly. Did it come already sliced?

Metal Hack saw & a vice
It isnt perfect but I think its close enough

The one thing I did find weird was that the secondary voltage was so small..
With 80 turns on the primary @ 120VAC & 0.5amps, and 304 turns on the secondary, I would have expected the secondary voltage to be way higher,. like 450VAC or something.

I started off with alot of windings on the primary (maybe 200 or so) and had 7.4VAC on the secondary.
I had to remove alot from the primary to get the secondary voltage up to 12VAC

Any ideas on why the secondary voltage might be so low?

Good job on the build there and commendable for being one of the few that have jumped in to try a replication.  I think more will try but just a matter of money and time to get to it.
    A couple comments on your results - A bridge rectifier (depending on specs) can drop the AC voltage quite a bit so no surprise it went from 12 volts AC down to 5.4 volts DC.  Also the Nanoperm or similar core here is key.  Regular ferrite and iron are not likely to get any good results.  Based on what Mav has said it sounds like getting the coil ratio just right may also be an important fine tuning point which will make a big difference.

For one thing, the transformer action is only related to the voltage across the transformer. I suspect if you measure the actual voltage across the primary, that it is much less than the 120VAC. Most of the voltage drop is across the lamp, which means the inductance is not very high compare to the lamp resistance.
If it didn't work, than it should behave and be explainable like a regular transformer with some flux leakage.

Also the bridge rectifier should drop about 2 diodes worth or 1.4V.

I have been looking at cores and if you used ferrite or other kinds they still vary in U between them. Here is a link for some cheaper cores...look at how even the ferrite one's U are vastly different. So when I get some money I'm going to get me the biggest core with the highest U. Look at all the cores they have by clicking on Products. I know these aren't nanoperm but heck they are cheap and you can use the highest U. Ferrites have the highest at this site. Just some info.

Also will a magnet stick to your shell Import? Just making sure they didn't give you aluminum shell..LOL.
