Laurent,   nice work!   Cool idea using fence wire.   I look forward to your test results.
Tell us more about the primary that you are using.

Wow, lot's of nice toys show up.

@TH

I just knew you could not resist a good slice of bacon and was expecting to get posterized in one way or another. Good move. I really got a sizzle out of it.

Thanks for the vid that does explain a little more what you are doing. Maybe if you do not mind, we could take this a few steps further so I and others can get a better grasp of the BITT.

First I would like to mention that the actual BITT build and the drawn diagram as used in the videos are not identical. In the diagram, one would surmise that the ends of the primary core meet the first O laminates, core to core. But in reality, as I see the build it looks like the primary center core has a thinner but longer ends that make the core into an "H" core then an straight "I" core and that this H core is not directly in line with the interior of the first O core, but it is placed on top of the O core. This, in my view will tremendously diminish the potential primary to secondary transfer from 100% potential transfer to I would say 10% transfer potential you are getting right now. Was this intentional?

Why am I saying this. Again I will revert to my previous post in which I suspect very "jovially" that a good portion of the primary to secondary transfer is occurring air-to-air and not via the flux. I do acknowledge that in your last video you kindly placed some pick-up winds per three core directions and have shown rising and falling voltage pick-up although we can also say the actual voltage levels are not a true quantification of the flux movement but they just show that there is flux there, and it is moving or being modified as per your secondary coil connection variations.

When you energize the primary and show the steep rises in the scope shots, given the voltages applied, this reactive input power of high voltage low amperage cannot all transfer from the primary core to the secondary O core given the small surface area that both share, so some of that input energy has to go somewhere and I wold suspect it is creating a greater magnetic field around the primary coil.

So again I would urge you to try a test of the same running method but add any third coil, cored or not, placed on top of the primary so it is held about the same distance as the secondaries are and measure any voltage output from there, just so you can get a feel of the air-to-air potential, if any. Just place the coil on two pieces of wood atop the primary and run it. This is critical to either include or preclude this from the overall equation.

I realize you have given this to some pretty high level guys to inspect, but this does not explain why it is working, only that the numbers are of interest.

The other point I would like to expand on is the addition of the outer O core. As you show in your Video 4.0 with the three pickups, P, S1 on inner core, S0 on outer core. I do not really care if this is showing OU or not as it is not important at this stage.

The bulb load is on Secondary S2.

The applied energy to the primary was not identified verbally but once the scope showed the rising waveforms, I could see on the input ammeter located above the scope was reading an average of 6.1 amps and the input voltmeter was reading around 33.65 volts coming from your step down transformer which gave a good humm as well, and this while the bulb was loaded onto S2.

Secondary S1 is left open.
When you applied the above indicated power level to the primary the energy transfer to S2 is 9.87 volts at 0.83 amps.

Let's look at each test stage thereafter.

1) Then at no load on both secondaries, you showed the pick-up coils were showing as follows.
P = 0.742 volts
S1 = 0.390 volts
S0 = 0.008 volts

2) You then put S1 on load I imagine by shorting the coil ends together and the pick-up coils were showing as follows.
P = 0.741 volts
S1 = 0.059 volts
S0 = 0.078 volts

3) You then put S1 off load and S2 back on load and the pick-up coils were showing as follows.
P = 0.733 volts
S1 = 0.687 volts
S0 = 0.089 volts

4) You then put both S1 and S2 on load and the pick-up coils were showing as follows.
P = 0.693 volts
S1 = 0.330 volts
S0 = 0.008 volts

OK, so what this tells me may be somewhat different then what you are indicating. Again let me emphasize that the core to core surfaces that are in actual contact between the primary core are minimal and also the contact between the inner and outer O cores are also minimal in that they only touch together on the straight edges. The flux of the primary has to travel through the inner core before it can reach the outer core. This gives you a primary flux, a 1st stage flux on inner core and a 2nd stage flux on the outer core.

Also, don't forget that the secondaries are wound over both the inner and outer cores so that only half of each secondary wind is influenced by the inner core and the other half of each wind is influenced by the outer core. Given this winding format, you have to realize that any 2nd stage flux has to go through the first two stages before it can show up and this is evident in the low S0 numbers in Test 1 and 4.

Moreover, one could "speculate" that the increase in flux in S0 in Test 2 and 3 is not transfer core to core, but that the primary flux goes to the 1st stage flux that energizes half of the Secondary coil of which the other half of the same secondary coil then energizes the 2nd stage flux found in S0. This is why in Test 4 when both coils are energized, each half of the secondaries over the outer core are canceling themselves. Sounds complicated I know.

The cancellation or manipulation of this flux movement is similar to what we have seen in the MEG device and other similar devices, except that your BITT is using more channels of potential transfer, that is if you can show the transfer is not occurring air-to-air. 

Also, I would be very curious to know what the result would be if you did the following. Apply the power to the primary. Apply a make/break onto S1 so all it does is connects and disconnects that coil at an adjustable frequency while S2 is loaded with the bulb. I am thinking that while the primary provides the initial flux, pulsing the S1 on/off will create even more output onto S2 because you will be creating flux waves. At a certain frequency this should create some interesting peaks while not overtaxing the primary.

Of course, this post will self-destruct in 5 seconds and should you or any of your devices be caught by the enemy, we will disavow all knowledge of your activities. Good luck in your mission.

Thane, Wattsup,

Thanks for more details and putting summarizing data here.
I can use those for my simulations.

The practical setup indeed differs quite significantly from the theoretical drawing as Wattsup indicated. Flux in the setup will have more difficulties to change paths than in the theoretical model.

I got a bit further modeling the BITT in FEMM and using Octave scripting.
B.t.w. I am modeling the theoretical model from the drawing.
This weekend I might have first results that we can compare with the numbers that we have now.

@TH

I would like to maybe chime in to clarify something that I should have said in my previous post that may have left it in a sort of limbo which would not be a good thing. Especially with so much bacon on the frying pan. lol

One way to learn more is if the bulb was replaced by a dioded capacitor, then you could see the exact voltage levels that are being produced by the primary onto the S2. A bulb, with a meter on it will show the voltage under load but it only tells you half the story, but a cap will show you how high the output voltage can actual sustain itself. If the load with bulb shows 9.87 volts at 0.83 amps, then you try the output on a dioded cap and the cap reads 10 volts versus if the cap reads 120 volts, each of these results would tell you a greater part of the story. At 10 volts, this would confirm that amperage is piling up in the flux transfer before the load, while if it read 120 volts, it would say if the output was actually even more reactive then the input and was simply condensing on the bulb load itself.

Also, don't forget that the device is being fed AC. So when you open or close the S2, or load or not load the S1, the flux is still continuously moving one way and the other way switching 120 sides per second. In your explanations, it seems like you are explaining more a device that is being supplied DC then AC, since if it is AC, you then have to consider two directions at 60 hertz. For each S1/S2 variation, you have to consider each flow path alternating.

Anyways @TH, please keep up the good work. This is very interesting stuff. Don't only look at the OU aspect because it kind of has a tendency to blind people from what is really happening or from looking deeper. Sort of like only picking out the bacon from a good club sandwich. Not many people have the wherewithal to juggle around flux like you are doing and I personally really appreciate having seen this build.

@Wattsup,
A diode capacitor might work in a milliwatt setup, but here we are talking Watts, so you would need a real BIG capacitor to measure AC output power in a reasonable amount of time.
