This link was so cool, I had to pass it along...http://205.243.100.155/frames/longarc.htm#500_kV_Switch.

It is a video of a powerstation opening a half million volt switch and it creates a 100 foot arc. It is about 1.5mb and if you have sound, its even better. Let me know if this link works.

yeah it works !!! man the transformer fire just sounds NASTY!!!!! i my self got shocked working on a neon ballast 12000v got knocked on my butt and it scared me for life always respect the beast aka "electricity" aka juice 

imagine if a lamp could tolerate this much power,it would be bt-240000 and would have a e-20000 super huge mogul base.
