Thane, gaps like the image below has?

THE TERM "AIR GAP" IS A MISNOMER - IT DOES NOT MEAN LITERAL DELIBERATE AIR GAP.

FOR EXAMPLE, EVEN IF YOU MASH TWO PIECES OF CORE TOGETHER WITH A HIGH PRESSURE CLAMP - YOU WILL STILL HAVE AN "AIR GAP" FOR ALL INTENTS AND PURPOSES. THIS AIR GAP (ALBEIT INFINITELY SMALL) WILL HELP ENSURE THAT THE SECONDARY BEMF INDUCED FLUXES STAY IN THE OUTER CORE 3 (WHERE YOU WANT THEM ) RATHER THAN FORCE THEIR WAY BACK THROUGH CORE 2 (WHERE YOU DON'T WANT THEM ) - WHICH WILL INCREASE PRIMARY CURRENT BECAUSE THE PRIMARY NOW HAS TO PUSH FLUX THROUGH A HIGHER RELUCTANCE FLUX PATH CORE 2 ROUTE.

THE AIR GAP BETWEEN THE PRIMARY CORE 1 AND CORE 2 DOES THE SAME THING BECAUSE YOU CERTAINLY DON'T WANT ANY SECONDARY BEMF INDUCED FLUX HERE  UNDER ANY CIRCUMSTANCE - BUT THIS AIR GAP NEEDS TO BE SUPER SMALL TO KEEP THE PRIMARY CURRENT DOWN.

PS
IF I WERE YOU - I WOULD CHANGE YOUR DIAGRAM TO AN I CORE PRIMARY WITH TWO C CORES AND A TOROID CORE AROUND THE OUTSIDE. THIS WAY WHEN YOU OBTAIN A MANUFACTURER'S LICENSE  YOU WILL BE ABLE TO WIND A PRIMARY AND THE C's & BI-TOROID BOTH SEPARATELY ON CONVENTIONAL EQUIPMENT, THEN JUST SLIDE THE PRIMARY COIL AND CORE IN PLACE, A LITTLE TACK WELD  AND "BOB'S YOUR UNCLE".

B.t.w. In my country (Holland) private consumers do not pay for consumed blind power.
But companies do pay for this already.

Sir
Its My job to ask the dumb questions [as rarely as possible].

Whats "Blind Power"?  -> ?

Chet

Chet, actually it is written in at the top of the same reply.
In short, blind power is power with power factor 0 (PF=0).
In Holland private power meters don't measure consumed power with power factor = 0, so they are 'blind' for this kind of power consumption.

Power has a power factor of 0 when voltage and current are 90 degrees out of phase.

The measurement method you use is a bit doubtful though, using a current clamp to measure magnetic flux. I would just use a few (10-20) detection windings on those cores to measure the voltage over those windings with an oscilloscope. That probably will give you a more reliable and accurate representation of the local flux.

IF SOMEONE TRYS THIS EVENTUALLY...
REMEMBER THAT A VOLTMETER READS THE NET CHANGE IN MAGNETIC FLUX / TIME.
SO IF YOU HAVE TWO SECONDARY COILS ON THE SAME LOAD BOTH INDUCING THE SAME AMOUNT OF FLUX - BUT IN DIFFERENT DIRECTIONS - THE NET FLUX THROUGH THE COIL WILL BE ZERO AND THE VOLTAGE WILL BE ZERO, EVEN WITH MAX FLUX CHANGE / TIME.

THAT IS WHY ONE OF THE PROTOTYPE COILS IS ALWAYS LARGER THAN THE OTHER FROM A PURELY EMPIRICALLY SCIENTIFIC PERSPECTIVE.

In short, blind power is power with power factor 0 (PF=0). In Holland private power meters don't measure consumed power with power factor = 0, so they are 'blind' for this kind of power consumption.

LET US BE CLEAR ON THE LANGUAGE WHICH CAN BE TRICKY  :

IF THE POWER FACTOR IS 0 THERE IS NO POWER "CONSUMED" PERIOD, BECAUSE THE METER READS THE NET POWER BY MEASURING THE INPUT CURRENT FROM THE SOURCE ON ONE CYCLE vs THE OUTPUT CURRENT BACK TO THE SOURCE ON THE OTHER CYCLE.

THE "$ COST" ACCORDING TO THE METER IS HOW MUCH CURRENT IS RETURNED TO THE SOURCE.
AND THE CONSUMER PAYS THE DIFFERENCE.

THE BITT USES PURE REACTIVE CURRENT/POWER  (PF = 0) BUT DELIVERS REAL POWER TO THE LOAD(S).
SO THE NET METERED COST IS $0.00 BECAUSE THE INPUT FROM THE SOURCE ON ONE CYCLE (1/2 SINE WAVE) EQUALS THE OUTPUT RETURNED BACK TO THE SOURCE ON THE OTHER CYCLE ( OTHER 1/2 SINE WAVE).   

NET EFFICIENCY = INFINITY 
Just as it ought to be in a LOVE based INFINITE UNIVERSE!
