OleI am not so concerned with our alternator guy.I now am wondering what was happening to drive a 90 volt treadmill motor like a Dremel tool, doing very high rpms, considering the wire size was so tiny, coming from the spiral Tesla coil.As it is, with another experiment, I am testing these motors running off of the product of a bridge rectifier attached to the brushes to run the next motor in line , and so on, for as many big dc motors that I have, and noting the rise in voltage from one, to another, as well as thecurrent of the power supply.It is a very simple experiment, yet, is showing interesting progress.Cheers Warren

Hi Warren,
"By upping the voltage one can carry higher amperage at high frequency."
The wires still heat according to the amount of current going through them. It doesn't matter if the voltage between them is high or low or even zero. Only the power transfer is changed by changing the voltage at a given current.
The power dissipated as heat in the wire equals the current through it multiplied by the voltage along the wire. This is not the voltage between the wires which doesn't affect the power dissipation. The voltage along the wire is the resistance of the wire multiplied by the current through it. Thus the power dissipation is also given as the current squared multiplied by the resistance of the wire.
The person in the video doesn't give much information and the video doesn't show much neither. If he intends to have 90A or perhaps 3 x 30A through the wires the insulation will probably melt of burn.
Regards
Ole

JameBe kind. .George makes a valid observation. By upping the voltage one can carry higher amperage at high frequency.I am.more interested in seeing the units working, if that is possble.Although it may not apply in this case,When I made the induction stove top Tesla pancake coil, it was only very fine speaker wire yet to my amazement, I was able to drive a 3 hp tread mill motor like a Dremel tool, when connected to that skinny wire.I did not connect it to a scope so am quite clueless about the nature of the signal. However it is impressive that permanent magnet dc motors provide such dynamic results with such inadequet wires.This conversation reminds me to get back to those induction stove experiments with Tesla coils. They are super easy to make, and I haven't even unpacked my new induction furnace from the winter move of my studio.I meant to remind Sven that they work so well, and might be worth a try for high voltage concversionCheers Warren

Darrell,
I've been in the electrical trade for 64 years and those wires are too small tocarry 90 amps and they would be flat out trying to carry 30 amps, so I didn't watch all the video.
