Understanding electricity in the TPU.

Those white deals look like highfrequency autotransformer cores.  See how they are squared off.  This is so a brush can ride around to divide the primaries from the secondaries.  I knew I had seen them before.

@sparks

Please elaborate a bit more. Do you mean like the core they put in rheostats.

   It doesnt choke off voltage like a resistor it transforms the current like a joule thief.  You can modify the ratio  of turns in the primary by moving the dial on the autotransformer.  So it can be used in buck mode to lower the voltage to the load or the boost mode to raise the voltage to the load.  Highfrequency ones use an iron ceramic combination.  Could act as a variable inductor and I can vaguely remember seeing these on the back of old tv set picture tubes.  The wires potted inside lead me to believe SM was using them as a highfrequency transformer.

Exactly! Steven Mark was at home in televisions, some of hes idea comes from there
The thing is that you need to use your intuition sometimes, not the human intellectual mind, to get the good ideas...

Sometime i have dreams when im in a sleeping state and i make 100% working Ideas,
Lets concentrate on TPU in our dreams,
FOR HUMANITY!

Hi All,

Did anybody look the thing from the angle of diamagnetism? As I think this is the reason of the thick copper around the perimeter. Copper has strong diamagnetic properties besides a relatively cheap and good conductor. That is why I think Tesla and SM preferred it.

For those who don't yet look into diamagnetism:
You get a copper tube with thick wall (I mean THICK), erect it and drop a strong disk magnet into it - possibly 2-3mm smaller diameter than the copper tube's internal diameter - then the magnet will reach the end slowly. You can do the same thing with a thick copper bar if you tilt it and drop a magnet on the top, it will slowly glide down over the copper's surface.

SM and Tesla perhaps used the external coils to preserve the created magnetic poles over certain segments and moved it to other non-magnetised segments of the copper ring. Therefore if you know that how to connect the wires wrapped around the thick copper you can preserve a rotating magnetic field initiated by e.g. a high voltage spike.

Kind Regards
Tony

PS: If you're interested I can upload videos tomorrow as I exceeded my data allowance and will be zeroed tomorrow. (~12 hours to that )
