Found more info regarding plural primaries in this Korean patent: https://patents.google.com/patent/KR20080085122A/en

Image is from the patent. The patent uses a pipe as secondary to heat conductive fluid, but states a plurality of primaries to increase the pipe emf without increasing the secondary turns. Also confirms that output emf is turns ratio multiplied by number of primaries (2nd image, 4 is number of primaries)
Hey Antijon

Interesting.  I can see if more individual primaries when powered in parallel could produce more emf from the single secondary because of stronger/denser mag flux with more primaries. If this is so, I think it could destroy the idea that it is the E field that determines the voltage ratio between the primary and secondary, which would be contrary to Faradays explanation, of which I like to follow. ;)
It would have been interesting if the pat had also shown and described if the primaries were in series.  If this pat actually does the exact same as the 5 core is supposed to, then I will have to think more on why there is an increase of sec voltage on the sec of the 5 core if it happens. The inducing of 5 separate sections of the sec of the 5 core and those individual section voltages adding up, may not be as I thought, because in the pat, all the primaries affect the secondary as a whole.... hmmm.
OK should have something to show in a bit.
Nice find!   ;)

Just flipped through some old pics and found the ones of driving the light bulb. Wasnt an auto bulb. 50w halogen.  I see I had a bridge rectifier and cap on the output. Lol I would think the halogen filament might be hard to drive with 30awg. But it did.

Ok. Initial test does show secondary voltage increase as I add primaries in series successively from 1 to 5


so the audio amp had input of 1khz and set at 20vpp


through the 6.2ohm ballast resistor im just showing the primary pp voltages vs secondary voltage. Secondary is bifi in parallel at .5ohm.  Wish I still had the number of turns but I believe the number of sec is less than any primary, so the single primary voltage vs the sec voltage should reflect that ratio. The wire for each turn of the secondary is a bit longer than a single primary turn. Maybe 3 to 4 turns of primary to one turn of sec wire length. The 2 bifi windings in parallel will make for half as many sec turns..


1 primary   11.2vpp     secondary   2.6v
2 primary series   14.4vpp( 7.2vpp per series primary)     secondary  3.4vpp
3 primary series   16vpp( 5.3vpp per series primary)        secondary  3.72vpp
4 primary series   16.8vpp( 4.2vpp per series primary)     secondary  3.84vpp
5 primary series   17.6vpp( 3.52vpp per series primary)   secondary  4vpp


Didnt have time tonight to go through and adjust for similar input voltage to the primaries. Will need to chart the ballast resister voltage also.  So far 1 primary at .7ohms with a 6.2 ohm resistor in series, the primary voltage doesnt make sense. May need to change freq.  Will do more to work this out. this was just an intial voltage test. Also I will find what the sec bifi resonance is and pick a freq to avoid that so I can run the sec in series instead of parallel.

looking at the numbers now while at home to write this, it looks like if the primary voltage remains the same, like say 16vpp, for 1 or even 5 primaries in series, the sec voltage just may remain at or near 3.72vpp as shown above, like I had anticipated in my earlier post. For me, that is awesome. If further testing shows that as we add more series primaries and the sec can still drive a similar load, then this is what I have hoped. As we add more primaries, the input power will decrease while the sec output remains the same.  Hopefully.  There has to be a point of where we can breach 100% eff as we double the number of primaries.  Similar to doubling speaker driver numbers.   

As I get experienced with this I am already coming up with what goes into the next build with more cores and primaries.  Im thinking that it should be safe to say that just powering a single primary, that the turns ratio with the sec should be standard.

Ok more in the coming days.  Need to hope for similar or better sec power output as primaries are added in series.  If so, then this WILL be the building block toward true OU.  ;)   Each doubling of series primaries decreases input current by half. ;D

Today I thought on things a bit.  Just got to my shop. Have a bit of time here. I decided to get rid of the resistor and just run the amp to the 5 primaries all in series. I rearranged the terminal strip so that all the primaries are wired in series, like I had it before borrowing the strip for other things ::) . That left me with 4 terminals for the sec bifi windings. So I had an extra 2 that I cut off.  Dont know why I had it that way this time around. ???
Tried for resonance on the secondary and the freq must be higher than 20khz, so no worries there. I like resonance, but I dont want it here or else we may not learn whats really going on with the multi core setup and its workings. Maybe on the next one I will wind more turns on the sec to try resonance with it all and get it down to some audio freq.
So I went direct from the amp, single channel, across the 5 series.  The sec must be less turns than the primaries as its voltage is still lower than the primary. Need to fix that on the next one as I would like a 1 to 1 ratio, in my mind anyway. :D
So I went though some of my lt bulbs and found a t921. Supposed 16w at 12.8v. 

Have the scope on the primary and another scope probe on the sec. Primary p-p input is 58vac and sec is 30vpp. When I connect the bulb across the sec the sec voltage goes down to 18vpp and the bulb lights up bright. The primary voltage remains solid but shows a phase shift when the bulb is connected.

So I will devise a measuring setup for the in and out and see what we get from there.
Short YT vid should be ready in 5min. Ill post the link when its up.  Nothing special. Just somethings so far.

Just got the comments on for the vid. I thought the setting for the vid 'made for kids' meant is ok for kids and comments were auto disabled.
Anyway...

Ok, gotta git. Hungry. Will fall asleep to thoughts of an 8 core and how I wish to wire it. ??? ;D
