I would have to say that is the exact equivalent of Tesla's bi-filer solenoid winding, without the splice (externally) .

I think the difference is that in Tesla's bifilar (pancake) coil, each part of the wire has besides it, a wire carrying current in the opposite direction. There is no part of the wire that is adjacent to another wire with current in the same direction. So there is practically no self-inductance.

Here, in artist_guy version, it is basically two conventional coils side by side, with one that has reversed wind direction. But each coil has inductance, and being on the same core, I'm not sure of the resultant inductance of the assembly, but I would think it would act very different from Tesla's.

I still would be interesting to try it, in case it would have properties that could be beneficial to our goal.

New TESLA SERBIAN! Milutin Miletich is a retired technology engineer (not electrical), , he has invented something extraordinary. Alternating current is filtered and flows through ONE wire only and powers a classic light bulb. His words are that he was able to join positive, negative and the ground into one electrical flow, and that is not all - human can hold the wire without any problems! The power is 220V in Serbia (you can see in the video that he is using the regular power supply), and 220V powers the light bulb, so voltage stays the same.
There are no sparks, the power is totally safe, even you cut the wire, the flow will stop but without any sparks. So safety is one of the greatest benefits.
He says that he was able to make sure that no electrons would escape the wire. His claim is also that there are significant (drastic) savings in power consumptions (he is using it for his water heater and thermal blanket). He also says that this type of current can heat the wire up to 1000C and be used as a heater, and that all high voltage cables could be replaced with a much smaller profile wire. He also claims that this setup can be adjusted so that 5Kw flows through 1mm wire. With slightly bigger profiles, much more power could be used.
He says he had worked on this patent for 20 years, and it is now being evaluated by the patent office.

WOW !
That's fascinating.
This really deserves a new thread.
While reading your description, I almost had a stroke at the last line, when I saw that he was going to the patent office.  NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO ! ! !
There goes another great invention that will be suppressed, like the rest of them !

When will people learn ?

Hi altair,

Actually, there are actually four different kinds of Bifilar-wound coils. These depend on the connections and the direction that you put the current in each one.

If we assume (for example) that the bifilar coil is a pancake coil (like Tesla's original one), then you can do one of four things:

1. Hook the windings together in parallel with the current going the same way.

2. Hook the windings together in series with the current going the same way.

3. Hook the windings together in parallel with the current going opposite directions.

4. Hook the windings together in series with the current going opposite directions.

Each configuration creates a unique series of characteristics and circumstances depending on what you want to do.

Tesla's original Bifilar coil was wound like #2 in my description. The idea is to increase the electrical potential difference between the individual windings without canceling the inductance of the coils. This way, the inter-winding capacitance can be greatly increased to allow the coil to self-resonate at lower frequencies.

Why the lenz effect seems to go down and output of the generator becomes positive relative to the overall system I am not certain at this time, I suspect a resonance in the device but have not swept the coil/bridge/Cap with a signal generator to verify this. It could be a new phenomenon that is not understood, I just don't know.  I don't know if paralleling the coils increased the current capability of the system or dropped it into the correct inductance range (Parallel coils) to resonate.  I do know in the series coil configuration, it did not work in my system, I never reached a crossover point initially as probably the point was too low with the increased series inductance of the two coils (40-50mH)without magnets.  But remember, this is just a test rig.

Hi k4zep,

Nice to see you working on this with us. You may have missed some of our recent posts where Bolt and I were discussing the importance of tuning the device to resonance to really manifest the no-load power generation effect. Here's the links, one of which includes a formula you can use to determine what size cap to use with your motor given the RPMs you want to run at and a few other variables.
