A 91 OHM COIL AND A 53 OHM COIL.

THE INTERESTING THING THAT SURPRISED ME WAS THAT THE 53 OHM COIL WORKED BEST.

53 OHMS OF 30 GAUGE WIRE IS STILL HIGH IMPEDENCE - I BELIEVE HP'S EFFECTS ARE SIMILAR TO STEVE'S (CORE SATURATION RESULTANT ACCELERATION). MY MISTAKE WAS ASSUMING LAMINATED CORES REQUIRED HIGH #'s OF TURNS AS DID IRON CORES.

I DON'T THINK HE SAID THIS EXACTLY, I WOULD IMAGINE SHORTED COILS INREASE THE CORE HEATING BUT ALSO CAUSE THE MOTOR TO ACCELERATE BECAUSE THE CORES ARE SATURATED AND THE DRAG IS REDUCED BECAUSE ROTOR FLUX CANNOT ENTER THE COIL/CORES.

AGAIN HV COIL EFFECT IS DIFFERENT BECAUSE HV COILS PRODUCE LITTLE OR NO CURRENT WHEN SHORTED AND DO NOT INCREASE CORE FLUX LEVELS TO THE POINT OF SATURATION - AND HV COILS DO NOT HEAT UP AT ALL.

Not quite.

Induced magnetic fields act to cancel changes in flux, they will tend to cancel the flux from the rotor. (the magnetic flux in a normal transformer does not actually increase as the current through the primary increases, it stays about the same as the secondary cancels it)

The second point is that HV coils might have 1/100th or 1/1,000th the current but they have 100 or 1,000 more turns than their high current cousins and so their ampere turns is the same and they create an identicle magnetic field.

In fact from an outside perspective there is damn little difference between the 2 if both are shorted conventionally speaking of course.

MY FEELING IS THAT STEVE "LOST" THE ACCELERATION EFFECT WITH LAMINATED CORES BECAUSE THEIR RELATIVE PERMEABILITY IS HIGHER AND THEY DO NOT SATURATE AS QUICKLY. IRON CAN HAVE A PERMEABILITY OF AROUND 200 WHEREAS LAMINATED CORES CAN BE IN THE NEIGHBOURHOOD OF 10,000.

I DID TEST THIS A FEW PAGES BACK (PAGE 48) WITH THE SPLIT-PHASE MOTOR TEST.
HV ACCELERATING COILS REQUIRED LESS MOTOR INPUT POWER THAN WITH NO COILS AT ALL.

I missed that, very damn impressive! (I almost wish PB were here for you to rub his nose in it except spooks are not paid to admit anything so it would be as empty as his soul)  I think that you and possibly I should each have a web page or document or endlessly editable post that gives in your case your experimental results and for me the case for the aether.
