That sounds basically like the bifilar connected at one end.
with one winding having a (slightly) different resistance than the other.
Hmmm

What effect would one winding of bifilar with different resistance have on gen coils ? 
Sliders test looks to be with motor drive coil.  Also, shorting. 
Interesting results to say the least.

He connects a CFL bulb.
That's not equal to shorting......

Watch closely to the NXP data sheet, page 7.
You'll notice some resemblance with what we already have.

That's a good question. I can be wrong about this, but from how i see it,
the currents being induced in such a generator coil would basically
cancel each other out (for the case of equal windings).
With unequal winding you would have the same current as if you had used
just a single (or the difference of all strands) winding.
Please correct me on this, if i am wrong.

Slider should have also measured the input current differences between
the 2 power coil variants. If it has the same current draw, then he is onto something. IF he did that with his motor coil, that is.
He said in the youtube description :

QuoteThe two ends lots were then used as the power wires for the coil.

QuoteI powered up the motor and saw the usual speed to be expected from such a coil...moderate speed, fine, normal.
Then decided to basically short the coil with a regular house bulb - the rotor sped up to a never before seen speed !!!

So he is basically loading/short circuiting his driving coil.
Too bad he did not bother making any current measurements.
A lamp in parallel to the coil reduces the total resistance seen by the driver.

I made some progress on the wire twister yesterday about half way done. But I did get to play with the test rig for a bit last night and I did notice that I was able to increase the voltage on a bi-filer coil two volts peak to peak with the addition of the biasing magnet(s). I could not get the same effect on a single wire core. Also Zero fossil fuel stated yesterday that he thinks his will be a selfrunner by the end of the week, check out justin.tv for the recorded show.
