But, if the MythBusters did attempt it, they could send in Buster the Dummy into the most holy with a rope around his ankle so that if he got zapped or just died of natural causes then they could safely pull him back (without going in themselves). Maybe it's a job for Tim the Tool Man - the Binford Ark of the Covenant!
Does it say they did this for the high priest in the OT, or is that just Jewish legend...?
OK - past history: I made several "Jacob's Ladder" devices from neon sign transformers when I was young and crazy. They are those things that has two long wires in a long slender V shape, and as they vibrate back and forth, a spark forms at the base and rises up to the top...as I recall, about 2000 volts will arc across a bottom gap of about 3/4 inch. Another super-high voltage transformer I had from a big radar display put out about 40,000 volts and it made a huge vapor arc all the way up as it consumed a little of the copper rods. (until the transformer got burned out)...but I never saw these do a purple "corona" even in a darkened room. I know vacuum tubes can do it internally at around 300 to 400 volts.
My question was like the previous poster; how did they get that much voltage generated in the first place? And, of course, like the Archimedes solar ray gun, even if we did it somehow with modern technical know how, what exactly is it going to prove? (other than sounding like a very cool thing to do...)
I like the way Nathan Natas thinks!
