The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
Don't know the specifics re: peak voltage and current, but it must have made one HECK of a bang. Even short exploding wires are deafening - you feel the shock wave in your gut.

Yeah, I've experimented with exploding wires about a year ago. My power supply charged a 100uf energy storage capacitor to 4KV, and then discharged it through a triggered spark gap into a 30awg copper wire about 1 inch (25mm) long. As you stated, the exploding wire makes as much noise as a gun shot. One thing that I found while experimenting with various lengths and thicknesses of wire, is that when the wire is fairly long, then it no longer explodes, but rather just glows red or white hot and then melts. In order for there to be an explosion, the wire must be short enough so that it vaporizes quickly while there is still a lot of energy in the cap to create a plasma arc. I can only imagine how much voltage and current that's requred to vaporize the long wire in that article. It must be HUGE, and the capacitor bank must be huge also!

Yep that’s an impressive way to get rid of some copper wire, couldn’t help thinking if they fed it in the centre as there’s a support near the trailer with the equipment on, so was it formed by two plasma arcs end to end, or a bi-polar source? The voltage must still have been pretty significant, maybe huge pulsed power caps discharged in series like a marx type arrangement do you think?

Or use an array of tuned IR lasers with the pulses triggered so they fire within a few nsec. Result ought to be a line of plasma fireballs (air breakdown) and a very rapid lightning strike shortly after.
-A (applies for patent "Method of immobilising enemy tanks and artillery using induced lightning strike via laser plasma" )
That's an epic win. 1.2 miles? That's quite literally like lightning. The most I can do with lightning in my backyard is... watch it from my back yard. :O
