Anything is possible if you are creative enough. Who needs ISO/OSHA/DIN standards or safety precautions?

You’re thinking of AC ground. There’s also DC ground and RF ground.
I know next to nothing about RF, but does anyone actually run DC directly to earth?
Kinda. AC: https://en.wikipedia.org/wiki/Single-wire_earth_return DC: https://en.wikipedia.org/wiki/Pacific_DC_Intertie
I’m pretty well outside my wheelhouse now. I’m a ham and I’m learning about electricity. I’m certain others can explain it better than me. The image posted is a joke, that type of ground (dirt in a baggie) wouldn’t be helpful for AC or DC. I suppose it could change the resonance a bit as RF ground but it’s obviously not connected to an antenna system here.
Huh! I was aware of SWER, though not the name of it. But the DC Intertie is really interesting! I was under the impression that long distance DC is bad, but turns out it has some real advantages over AC.
I did at least understand that much ;)
