This robot stuff reminds me of something I read in a book about designing safety-critical systems. It was an industrial robot loading large sheets of steel into a big press at a car factory. This, happening at a fast rate, is obviously pretty "Staplerfahrer Klaus" to anyone walking into the work area while the robot is running, so they designed infrared barriers around the area to stop the robot immediately if anyone tries to enter while it's operational. Well, the first time they tested it, everything worked as planned. The barrier detected the entry, the robot executed a crash stop, and... the metal sheet ripped off the robot's grip and went flying into the next work station. Oops.

As the conductors diverge it becomes more unstable and the arc can't maintain itself, allowing the voltage to build up again across the conductors starting all over. It starts at the bottom because of the "V" configuration the conductors are in (arc forms at the shortest path).

I am imagining a day when some kind of existential thread faces earth and the only three people who can team up to save the planet are PhotonicInduction, Rodalco, and Kreosan.

Give the guy a break, he's using all the correct PPE of Heavy Duty Sandals, Cheap T-shirt, and friend looking out for him. Just noticed that the line between the two guys is NOT a makeshift harness of any sort.

It's not abandoned, otherwise they wouldn't be getting burned by it. Probably around 50 to 100kW going through it depending on if it's FM/AM or Shortwave. https://www.youtube.com/watch?v=eHnHncbUDoA Courtesy of the OSHA reddit:

That thing would have been a schizophrenic's worst nightmare.

I even screen capped it for posterity. Yeech. I was sleeping over at a friends house one day, years ago. Out in the boonies, known for being pretty close to a "hills-have-eyes" sort of area, no streetlights to speak of. So picture this: Long hallway, middle of the night, nearly pitch black, I get up to go to the bathroom...and hear whispering from the end of the hallway, near the front door. Since I'm the person who dies in horror movies, I went to check it out; it was coming from the speaker box connected to the front gate. I'm this close to calling the cops before I actually made out what was being said-- turns out there was some signal leakage resulting in Sesame Street being broadcast very faintly over the line.

I even screen capped it for posterity. Did a tech load-in for a stage show and had a horrible problem picking up a right-wing AM station on the amps. Nobody could figure out where the interference was coming from until the new guy helpfully pointed out he'd coiled most of a drop mic line around one of the metal light bars, essentially turning the theater into a giant AM receiver. Bled across the entire system. Good times.

 Terminix truck came in for an oil change leaking an upsettingly sweet smelling semi oily clear liquid from the locked rear cargo bed that was neither gas, water, brake fluid, washer fluid, oil, or coolant. Proper clean up and handling as per management: finish the oil change then throw some rags on the puddle and wipe it up.

I even screen capped it for posterity. There was an AM transmission tower right next to my freshman dorm in college that constantly bled over onto our electronics. Our answering machine had a "silence detection" feature that was supposed to keep the machine from recording dead air if someone called and then hung up without leaving a message. The bleedover from the tower was just above the noise threshold, so we would come home to several three minute messages (the cutoff time for incoming messages) of ghostly music.
