The Gabriel Device, possible COP=8

@Forest. You might be able to find what you want in old air-conditioning units, but only those ones that have inverters in them. Also I don't know what country you live in, so it depends on your voltage. Those in 120v countries might not have capacitors rated as high as those in 240v countries.

you can use a modified air cap (old tuner type) for HV  just take out plates to make the gap wider AANNNDDD  you can also use an old CRT (picture tube) as a HV capacitor that will hold lots of zap.  Suggest you keep it mounted in the old chassis for safety.

air variable capacitor from scrap aluminum sheets  you can build variable air caps but modify the design to leave big gaps for HV use.

Bessemer Steel will give you a great material for transformer action     Tesla used AU wire for voltage increase and copper wire for current increases.

Babit metal may also be a great choice if you can still find it.

Been thinking about the shorted turns.

In a normal transformer, as the secondary is loaded, the primary inductance goes down, as the load is increased.  So the primary is able to conduct more current due to lower impedance as the secondary is loaded.

So, if we have it that the primary is not affected by the secondary(shell game), and, we can only seem to get out nearly what the the primary uses, then, when we add shorted secondaries, it would act kind of like a tertiary to the secondary. And the tertiary, shorted current flow, might allow the secondary to output more current like the primary in a normal transformer, and maybe more output than without the tertiary.  Maybe   ;]  Always thinkin

Matt, you seem to have nice scope. Could you put probes on the shell ? Lets see what kind of eddy currents there are. Note, no idea if this is safe from scope point of view. If there is no difference between shell halves then maybe both shell halves are + signed on one cycle and - signed on other cycle. What happens if you take one half and connect it to ground, is there current ?

As for shorted turns, if you put cap there then perhaps oscillation frequency differs from the mains and you would get amplitude modulated primary which then reflects in secondary. Would be interesting to see scope shots with shorted turns using capacitor.

Also cap between shell halves might have some effect, or connecting secondary to shell halves, cap between shells and output from the shell. Lets do some sharp shooting in the dark !

Mag, I would suggest a 25-40 watt bulb in line with the secondary limiting its current for protection of the secondary.  Most FB's have a small current carrying ability some where between 20-50 watts.

Found a unlimited source of permalloy for virtually free.... Harddrives the brackets are permalloy, people usually just toss those or let you take the whole machine for nothing which is a good source for materials, I have about 10lbs of the stuff now
