What i mean is, who found out that we could rip the mots out of a microwave and arc off of them? and how long have people been doing this?

sorry for the dumb question tongue

Thats a pretty good question actually, ive been wondering that myself.
I cant give you an accurate answer as I dont know, but Id bet it was bored appliance repair men who found it first (they ripped on it apart for repair and knew what a transformer can do)

but an actual person? I dont know
there where probably many people before this where known that did this, but the first person to publish it and make it common knowledge for us, this will take a while to find.

The MOT wasnt discovered, it was made LOL.

But anyway what I dont get is, using Pachens law it states that 2.5KV will arc 2.2mm?. But the arcs are huge.

Experimenters have been arcing stuff for
ages. This guy , 74 years ago, looks
about the age of coilers, no?

Before MOTs transformers could
be ripped out of big tube radios.

Another question would be who was the
first to make a U-Tube.

Monkey see, monkey do.

LOL! Such a safe setup he has there. I think I know why that is no longer in print.

well yeah it starts an arc at 2.2mm but the current creates heat witch makes the air more conductive allowing you to draw the arc out.

It was an Irishman called Maurice O'Toole, the MOT is named after him.

I believe O'Toole discovered what we now call the MOT in early attempts to replicate the shrunken head techniques of southern New Guinea, see:

Harrison, Simon, Skull Trophies of the Pacific War: Transgressive Objects of remembrance. Journal of the Royal Anthropological Institute 12 (4): 817 2006

O'Toole is best remembered today for his encyclopaedic Instances of the Number One, as any maths student will tell you.

Actually - the MOT was discovered by Ernest Danial Mot while searching for wild transformers off the South China Sea. His party had almost run around and found it's way to what we today call Hong Kong. While scouting for more Mains to 12volt wild transformers he spied what appeared to be a high amperage specimen and found it to be both lower current but much higher voltage. He returned with several and raised them in captivity.

Nonsense, that experiment looks perfectly safe. Surely his chemistry apron would protect him from the high voltage.

Seriously, I wonder how many people died because of that.
