I looked at Sliders video again,  now I am a little confused.  Is he driving the motor with a seperate coil (maybe his relay coil from his earlier experiments)?  He also stated he was getting 150 Volts AC from the coil.   So is this a gen coil causing all the fuss?   Very interesting indeed.

Get your head around this one from Slider over at EF -

Slider's effect could be caused by an internal Spark Gap in the coil which is caused by a defect on the wire insulation. The CFL bulb could be causing a short so the flyback starts jumping the gap and causes all kinds of ringing and increase the RPM.

I mentioned this back May 31, 2011 Post:

Slider should add an amp meter to see what's happening to the current and also try a momentary short instead of the CFL bulb to see if it does the same.

just guessing : RLC circuits are called resonant circuits. You induce current in some exterior wire layer of the coil, which induces oposite direction current in the next layer of wires ( this will continue at each layer of wires ). This is why the propagation speed of the current in a coil is aprox L / R. Because the external source of flux will eventually kill the internal oposing flux. This is why you manage to store energy as magnetic flux in a coil. It is resonating ( self oposing inductions between the wire layers )

What happens if you short the end of the wires to produce 0 output ? Good question, might not be 0 as you expect it.

It would be an interesting experiment to wire a coil as in a muller design, 1 layer belongs to coil 1 and the other layer to coil 2. Separate the outputs and the output should be a similar but oposite direction of current. The idea behind this wiring is to be able to put a lot of wires that can soak up flux. Each induced layer is not generating current that oposes the next layer, they are allowed to flow to the output. My guess that this will greatly increase the current propagation time in the coil / increase the amount of energy your coil can soak up in a short period of time.
You could complicate the muller approach to the next step by using 3 or more coils. Each layer of wire would be a bifilar winding, so that coil 1 shields coil 2 to avoid the induction to not generate collision. at next step you should use coil 3 and coil 4. The precision to do this is insane. And you can probably not shield the coils properly from 1 another to avoid colliding induction. But you can improve them.

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.

Coil setup in your picture could be called non-inductive resistor.

I think you are right in the way you show that coil but wouldn't bifilar be done like this with what Slider is doing and this would yield a whole different situation.  I thought this is how bifilar is done generally -->  Borrowing from your pic for a quick and sloppy mod to show what I mean:
