Inside an airline cold-plasma ozone generator cold-plasma tube.

I just thought I'd drop in the very trendy cold-plasma reference in the title just so I can casually mention that there's nothing new about it. It's just the same old electrical corona discharge method of creating ozone that's been around for hundreds of years.
Certain companies selling ozone generators seem to be implying that it's a radical new and secret technology.

This unit wasn't quite what I was expecting inside. I did guess correctly, but it's actually a bit more specialist than I was expecting. I'm not sure what plastic the end caps are made of, but I would expect them to be the most likely component to degrade in the concentrated ozone.

The most exciting thing about this unit is the horrifically spiky sounding power supply. I was expecting a reasonably loud hiss, but not the sharp rasping 50/60Hz buzz that accompanied it.
There are much nice power supplies than this, but I get the feeling they've used this type because of its cheapness and simplicity. The radio hams won't be too thrilled about the electrical noise this thing probably generates.
There's something about it that hints at a very retro Oudin coil from the violet ray era. I'm going to have to try and depot the primary side from its secretive black resin.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
