@DeepCut,

              The output coils were two air core Radio Shack 24 gauge bifilar speaker wire coils wired Tesla series, different near to far end. The spinner was a 1" neo sphere with a strip of reflective tape seated in a hard plastic holding cup. The power coil was a spiral bifilar of the same gauge speaker wire driven by a 12 volt battery with a Bedini SSG circuit and charge battery. I laser tached the neo sphere and measured the voltages of both coils along with the RPM. The inductance on the output coils was around 850 Ohms apiece as I remember. I picked the spin rate up around 30K with the coil shorted, then tried the two and measured half the output voltage on each along with the same rate of spin increase on the neo sphere. Try it on yours and double check to see if our results match.

This is same fact everyone encounters..  http://www.energeticforum.com/218531-post8285.html

If your rotor momentum reistance is not too big, the speed up effect would actually make driving coils from generator coils

Cheers!

I think Zebok's (synchro1's) mention of the fact that the effect is shared between coils is an important design point.

This evening i did a quick test using two coils with the diametric magnet setup. (Bearing in mind that everyone's experience is different, ambient temperature, tightness of winding (resistance-stretch) etc)

So, the challenge is, multiple coils share the effect so it is factored between them.

I'm glad to say this small, two coil, experiment contradicted that result.

The open rotor speed, with no coils/cores present, was 28,000 RPM.

When i shorted both coils, ie, they are not at all connected, but individually shorted (just being clear !), the rotor got up to 25,000 RPM.

When i serially-connected both coils, then shorted them, the RPM was 27,950.

I think there's room for improvement.

Zebok i would also ask, were your coils bifilar, because that gave me a 400% increase in the effect ?

Here's to lightweight appliances of the future

I forgot to highlight the obvious advantage here.

I was only a few tens of RPM short of the open rotor speed with two coils/cores present.

More turns means a stronger AUL effect because CEMF has a direct relation to inductance.

I've ordered some materials in order to make my custom coil-formers.

Early next week i hope to make a hybrid coil that will overspeed the rotor.

In one of my early attempts i thought i'd done this, but it turned out the weight of the coil pressed on the rotor base, thus lessening the pressure on the bearing so the rotor went faster.

Now i have a fat, wooden base that stops the perspex from bending, so that's one fault negated.

I will do a video of the two coil demo tomorrow, it's 4:30 here and i am VERY drunk, had a very nice day today


All the best,

DC.

@DeepCut,

             Yes my output coils were bifilar. Your test results don't add up because both shorted coil speeds are less then the open rotor speed.
