Dang it, Jim 147, I'm sorry.  I pulled that math part out of the post on the grounds that I was thoroughly confused in jumping back and forth with exponential notation on the Windows scientific calculator*.  Forget it.  I'm going to bed.  Maybe things will be more clear in the AM.  Saturday mornings are better for that sort of stuff.

I was spectacularly underwhelmed when I shot a bunch of pumpkins(just after Thanksgiving) with my 5.45x39 Tantal.  Teeny, tiny little holes.

You did it wrong, there is supposed to be a small (or large) container of tannerite in the pumpkin before you shoot it.

So, Tallpine, did they just pop them with plain old AC directly from the transformer?

Actually, they hooked a transformer up backwards so that the current was back up to the line voltage - 15K or some such.

They fried various fruits and vegetables and even set a car tire on fire (and you thought rubber was an insulator?  :O )

Jim, see your PMs. 

I have a house full right now. I'm in the garage doing some work. (Working on some cold ones.)

The first CD box we ever used for the race car was rated in Joules  ??? I flipped through my books and found a conversion to BTU. That helped a lot. ;/  It did get me once. It left a pretty good mark.

I had a tech get between a transformer and a mag tube once. And he only did it once.

I didn't even think about hooking the transformer up backwards. That would be about the same as someone running a generator without a transfer or pulling the main. :O No wonder the power company doesn't like to see backfeed cables.

Use enough voltage and anything will conduct  =D

And, if you put the right thing in there (electrodes in a vacuum), you can create a ton of hard X-rays!

Think I saw someone get up to 3 rad/hr on the net in a home shop.   :O


I'm still surprised that you could backfeed a transformer of that many KVA without the inrush blowing every breaker along the way.

They had a high voltage breaker hooked in with the transformer.

They actually had to reset it quite a few times.

Very interesting demonstration.  You don't want to be anywhere near a downed power line  :O
