The Brnbrade Coil/Overunity?

[hartiberlin]

Hi Mr. Amos, did you try to put magnets on one end of the iron nails as Brnbrade did it ? I wonder what polarity his ferrite disc magnets had ? Opposing or attracting , if you go from one rod to the next one ?

@Jacob,
will move this thread again to the TPU thread, when I am again at my PC tommorow. Am now only on my PDA.

Brnbade has a stack of ceramic disc magnets stacked to each left side  of his ironrods as you can see in his pics, if you look closer. The question still is, which polarity do they have and what was the winding direction of his coils ? This plays an important role. If you made that wrong, the effects could cancel out..

@All
In case you agree this may pertain to part of what is going on...

I am not where I can do extensive test but I have done the following:
1. Apply a thin film of Al varnish to an AL tube
2. Wrap a few turns of varnish coated copper wire around it (with the Al varnish still sticky)
3. Check for voltage and find DC volts as in a galvanic battery.

I looked at the bottle of varnish and it contains Cupric Oxide for color and the varnish is labeled as costic.

Copper + Aluminum + acid = battery. My lunch was over so I don't know if it could be charged. A quick Google indicates the right combination could create a crude but effective diode  as a P-Channel and may also exhibit solar cell like properties.

I don't know how this may relate to oscillation, yet.

And since I can't test now I have two thoughts that someone may be able to verify.

Judging by the build page showing the numbers of varnish joints between dissimilar metals - having a respectible DC voltage appear with no signal may not be unreasonable.

Since aluminum is between coils the induction from one coil to the next winding may be reversed. Since an increasing/decreasing field applied to Al creates an opposing field in the Al the mag field from the Al to the next winding should be reversed of how we think induction works from one coil to another. Take the small coil wires and reverse their connections to the other coil 

I'll try it when I am home. I have not used Aluminum varnish before.

Use it or blow it off - your choice

@BEP,
what is Al varnish ?
Please explain in detail.

Does it put out more voltage or current in sunlight ?
Yes, CuO is a semiconductor and could be used in solarcells.

@MeggerMan
well built rods,
the question is, if the aluminium tubes are not to thick.
I guess Brnbrade just used thin alufoil wound around his isolated iron rods...

Too bad, he did not tell us, how many windings( or layers) of alufoil he wound
around it. Could all be important..
and how his winding directions of the coils was.

But to have oscillations you have to wind these coils this way, that
the transformer action supports positive feedback.
Also it is probably very important to have the 2 rods
pretty near each other, so the fields from them can interact and
the left side magnets can also interact and thus the rods have the right
premagnetisation levels.

Maybe it is working via the amplification of Barkhausen noise spikes, so
you have to get the iron rods into the right BH range, where they just want to
toggle ( flip) back and forth their Weiss?s districts,so you have to have the right
amounts of magnets at the side, maybe with a gap and not directly connected...

I really could only imagine, that the only way you get it to work is
to selftune this arangement to the about 180 Khz of Barkhausen noise jumps
and amplifying this via this backlooped transformer setup.

I don?t believe, that this thing puts out DC voltage, but it is probably just oscillating
in the Khz range, maybe on a lower or higher harmonics of the 180 Khz Barkhausen noise jumps.
