If they still were around I would give you the full 5 stars for this demonstration!
Imho OU without any doubt. Also to me this looks exactly like the unit Alexander Frolov has described and built. And here you show that exact effect, that when only one load is connected, you draw current, (as a matter of fact so much current that the voltage drops below the level needed to maintain light!), but when you connect the other load, the opposing flux of both coils works against each other! Perfect!
Woopy, I don't know if you ever did the experiment that I suggested but here is the answer: When you disconnect one of the loads then you have two paths for the magnetic flux to flow through: 1) where there is no load on the first coil, and 2) where there is a load on the second coil. Almost all of the flux "takes the path of least resistance" and that flux path goes through the disconnected coil. So almost no flux is left to go through the second coil (with the load) to the bulb is very dim
Hi Laurent, you know that Thane drove his primary coil at a higher frequency than the mains outlet ? He may even have driven the coil at it's resonant frequency, measured when it is on the core. I'm not sure how he did this but i will ask.
Woopy, I have a suggestion for you. I hope that you didn't change your BITT configuration yet.
Let's just examine the outer ring of your BITT. Let's say there are four sections, the top, bottom, left and right sections. The left and right sections have the secondaries on them connected to the light bulbs. Let's investigate the changing magnetic flux in each of the separate sections when you do the two parts of your test.
2nd: To investigate the changing magnetic flux in each of the four sections you can add sensing coils to each section. The sensing coil is very simple, just wrap 20 turns of insulated turns of wire around each of the sections. For the left and right sections where you have the secondary coils, you simply wrap the sensing coils around the top of the secondary coils. When you run your experiment, either make multimeter AC voltage measurements or scope the outputs of the sensing coils.
3rd: You never put a load on the sensing coils, you just measure the AC voltage with a voltmeter or connect a scope to the output. All sensing coils should have the same number of turns.
The higher the AC voltage you see across the sensing coil, the more changing magnetic flux there is going through the corresponding section of the BITT. This allows you to see where the magnetic flux is flowing inside the BITT.
So this will give you insight into what is going on when you run your test.
4th: Another comment about the sensing coils: You do not need to make the sensing coils long so they cover most of the quarter-section. You can wrap the 20 turns of wire all in the same place. There is nothing special to worry about, just wrap 20 turns of insulated wire in roughly the same spot. With no real load on the sensing coils (the multimeter or scope is not a load) the sensing coils will not affect the operation of the BITT at all. Hopefully they will help answer your questions.
Hi Laurent, i ahve limited knowledge but i think it's better if you have lots and lost of seperate wire, with good spacing in between. I am using I-section laminates and they increased the inductance by a factor of around 400 %. But that is just in coils though i assume it should work the same in a transformer core ...
Hi DC the core is made with an insulated fence wire (the thinner i have found in a garden center. It is one wire rolled continously to get the outer and inner core . The outer core has more turns that the inner core. So i wonder if it is a good core, because i don't know if the eddy current follow the one wire or works as per separated insulated laminated core.
I will probably try to cut the cores in 2 parts and rebound them wit some overlaping to see the results.
The primary core should saturate a bit for good operation.
According to the theory of Thane, a slightly saturated core has higher flux resistance due to the lower permeability. In such case the BEMF prefers the outer cores rather than the primary core.
If they still were around I would give you the full 5 stars for this demonstration!

Oh both secondary connected parallel, ok :)
A perepiteia motor shorted to that would be magical :)

Hi Laurent, thanks for sharing. Does the fence wire come insulated or bare ?
