Subtitles unavailable. He appears to be generating Hi Voltage power with a rotary spark gap generator. You can see the spark from his right hand.

Basically its a mechanical joule thief.


He explains a high rpm , high torque mechanism
made from a crank and a worm gear
Hand cranked drill or fishing reel, etc.
This is for the toothed wheel used for the rotary spark gap.


He talks about the inductance of the transformer matching that of the motor
And how important he feels this is that they match.


He talks about efficiency and how operating the motor in pulses
is better


Because you get the first pulse from the battery
Then the collapsing field between the gaps
So its 2x power he says


And something that means equal reaction
From what i can tell the motor sends the kick back to the transformer
during free spin is i think what hes saying
using the flywheel generation to feed the motor out of phase


Then he shows a higher power motor ran off the inverter from a plug socket
first without the feedback loop,
then with it to demonstrate that there is more power
(harnessing reactive power?)


Then he shows it again with a (rotary toothbrush?)
then again with a bench grinder - generator combo under load

Thanks for translate

Here he is using the hammer on a twin chime wind up alarm clock to interrupt the circuit. Lester Hendershot used a door bell similarly.
