Give him time; I'm sure he'll get there eventually. He might even convince himself that by adding a secondary winding to his inductor plus a rectifier diode, he can feed some of the inductor's energy back into the battery to keep it perpetually charged.At least he's not aiming to run it from a PP3 battery.

Good point. Wouldn't surprise me to see a supercapacitor appear in that thing soon, either...But I don't need a lot of overunity. I just need a little to make it work therefore it should be possible.
Not surprising. People who engage in magical thinking (my term for it in this context is "voodoo electronics") often get really upset when people try to debunk their precious notions and set them straight. Some get downright hostile.The original poster apparently deleted all of his remarks and went off in search of a more "helpful" audience.

A mid-sized modern steelmaking furnace would have a transformer rated about 60,000,000 volt-amperes (60 MVA), with a secondary voltage between 400 and 900 volts and a secondary current in excess of 44,000 amperes.
looking up arc furnaces provided some interesting results, and a whole new level of "ming boggling"...
i had a friend who bought a welding rig rated at 1800W. he had tested it when he bought it, and it worked ok, but when he got it home it would work for about a second each time he touched the rod to the workpiece. the unit was on a 20A circuit, but the garage was the furthest part of the house from the panel. i stuck a voltmeter in the socket next to where the welder was plugged in. when he touched the rod to the workpiece the voltage would drop to 90. turns out the "20A" circuit was wired with #14 not with #12.
