I AM POSTING THIS PM FROM PB BECAUSE MAYBE HE (OR SHE) FINALLY HAS SOMETHING REALLY WORTHWHILE TO CONTRIBUTE... AND TO BE BLUNT - RIGHT NOW WE ARE SIMPLY LOOKING FOR A QUICK LAY.
Well, that wasn't really what I had in mind  PB ...
Stay tuned, polarbreeze maybe coming. Luc

OK, NOW THIS IS JUST GETTING OUT OF HAND.

Luc, a question about the power supply in the toroid experiment. I guess it's coming from the red and black wires that go off the top of the pictures? What is the no-load voltage at that point?

Also, I'm wondering if you've measured the output impedance of that supply - because of course that will have a bearing on what happens to the toroid input voltage when the loading changes. Any figures for that? Thanks.

PB

Luc, any news on this?
Thanks,

WHEN WE GET AROUND TO DOING "REAL TESTS" WITH AN OPTIMIZED PRIMARY (WE ARE STILL IN IMPROVEMENT MODE) WE WILL CORRECT THE POWER FACTOR OF THE OTTAWA U LAB VARIAC IF IT IS NOT ALREADY 1 - I SUSPECT THAT IT IS ALREADY CORRECTED BUT WE WILL VERIFY WHEN WE HOOK UP THE SILLY-SCOPE.

"Remember that the shorted coil has to act like a brake".Ã, 

I HAVE JUST COMPLETED A SERIES OF TESTS WITH THE 2 GOLD COILS AND THE GREEN COIL.

IT TURNS OUT THAT:

THE HIGH CURRENT GOLD COIL HC1 ALSO PRODUCES ACCELERATION WHEN ITS CORE IS COUPLED TO ANOTHER CORE COMPLETING THE MAGNETIC CIRCUIT. (as shown in the photos) THE HIGH VOLTAGE COIL HV2 PRODUCES THE MOST ACCELERATION - DUE TO THE FACT THAT ITS INDUCED VOLTAGE IS HIGHER - 100V vs 16V @ 686 RPM (just installed laser tach).

LUC AND I OBSERVED DECELERATION WITH THE HIGH CURRENT GOLD COIL HC1 WHEN IT WAS INSTALLED AS A "STAND ALONE" COIL..

So putting all these various things together (and bearing in mind there's a lot of data missing, so there's some guesswork here), maybe something like this:

1. Stable condition (baseline): the green coil, when shorted, is dragging on the rotor in two places: (a) as a magnet passes its own ("green") core and (b) as a magnet passes the other ("gold") core (because of the magnetic field from the green coil passing through the gold core: they are magnetically coupled).

2. Unstable condition: one or other of the gold coils, when shorted, produces a magnetic field in the gold core which opposes the one (in the gold core) from the green coil, thus reducing the drag on the rotor at that core. This pushes the system into instability. Why is it opposing? Perhaps because of different magnet polarity, or perhaps because of the relative physical positioning on the cores, or perhaps for some other reason. Why is it different for the two gold coils? Perhaps because they have different windings (turns) so one is more effective than the other at cancelling out the "green" field in the gold core; or, again, perhaps because of their different positions on their core.

I'm not sure that the instability mechanism is the most important question though. The more fundamental question is whether pushing the system into instability, however you do it, can actually result in any power gain because as I said before this has to be about power, not about speed.
