We made a hot dog talk with RF [video]
- biomcgary 3y agoIs the hot dog vibrating to produce sound or is the sound from hot dog derived plasma? The auditory frequency distortion seems minimal, so I'm betting plasma.
- geerlingguy 3y agoIt's the plasma—the hot dog was just a convenient path for the energy to flow. The actual material vaporized pretty quickly, definitely don't touch a live AM tower while standing on the ground. And probably ever, unless it's locked out and de-energized! (Especially if you're not a radio engineer or tower climber.)
- RulerOf 3y agoAny more details on how exactly that works? I've always associated plasmas with a buzzing noise but is that because they all vibrate?
- geerlingguy 3y agoMost of the ways we generate plasma aren't AM waves (amplitude modulation). They're similar to the waves you see in a speaker wire headed out to the magnet to move the speaker cone. As such, the power causes the plasma to move around in understandable tones.
- biomcgary 3y agoThanks for the reply. Love your work.

- gambiting 3y agoThere's loads of videos of bored russian teenagers doing this with leafs and blades of grass held with their bare hands too, but yeah.....pretty cool. Only works with AM radio as far as I understand though.

- mock-possum 3y agoWow the arc utterly obliterates the hot dog at the point of contact.
- garciasn 3y agoDon’t ever touch a tower. Important safety tip, Egon; thanks.
- pyinstallwoes 3y agoEgon?

- chezball 3y agoWhy in the world is the fence around that so short? This is nuts! I would have jumped that as a kid to climb the tower. Probably not in bare feet or the rain. It seems strange to not protect this better (yes, i know, kids are not supposed to be there, but kids are (properly) designed for finding trouble.)
- geerlingguy 3y agoThere's a small fence around each tower with signage indicating the RF danger. Then around the whole property there's a horse-height fence, with a locked gate. And around that there are a few miles of soggy farmland, so it's pretty low risk. Site plans have to include certain safety precautions, and fence type, placement, height, etc. are all submitted to the FCC when a tower site is designed or rebuilt.
