Please tell us you are pulling our leg. This is so obviously stupid and fake. “Car dynamo” no, it is an 12v RV water pump motor. And the little dc motor with the timing belt gear is just being spun by batteries in the wall wart. 207”volts” of what? I don’t know that meter model but let’s pretend it works and it indeed read “207 volts. Let’s assume AC. A simple battery powered inverter can easily be hidden in that power strip to get that reading. Open up the cases of the power tools and hide a battery in there with a few cheap motors to make it spin and all the plug does is close the circuit. Obviously the guy has access to a bunch of old power tools and motors. Probably has a repair shop and likes to play around in his spare time as an electrical “magician” to entertain and baffle the villagers.
Notice he never unplugs the feeder plug? Because if he did the power tools would keep running. It is producing noting. It is just completing the circuit to the small motor run by the batteries (maybe kicking on a transistor or relay). All the magnets are doing is providing enough force to overpower the torque of the smaller electrical motor hence he gives it the little push ( like what a starter relay does in any AC motor).
You gotta be joking us, right?
“Notice he never unplugs the feeder plug? Because if he did the power tools would keep running.”
Yeah, I noticed that, too. It’s a magical power strip!
