But then - I simply can't wrap my head around getting DC to flow continously thru a cap, transformer (or an antenna),

To be honest, I can't either. I would have been right there with you. The system is one light second in width, so we'd have at least a second of dv/dt to keep current flowing through the capacitor. And it's a fairly complex RLC network, so it would probably ring a bit... that's where my knowledge ends. I haven't taken any courses in transmission line theory and it just all turns into magic at that point. But then I was reading through the comments and and there was a bunch of conversation that was way above my pay grade. Someone seemed to come to the conclusion that just the inductance and capacitance gave 800 ohms of DC resistance. I have absolute no idea. Maybe? I dunno. I didn't even know that was possible. I will have to defer to people smarter than myself on this one. All I know is at least some current will flow as soon as you close the switch, but beyond that I really can't speak to it.

I think you only watched the first 15 seconds and the last 60 seconds of the video. I mean yes there's an ad for smart light switches at the end of the video, but that clearly has nothing at all to do with the rest of the video. It's a science video.

An attempt to insult me serves no useful purpose

An attempt to insult me serves no useful purpose

How on Earth did you find an insult in that statement? I think you watched a few seconds at the beginning and the end, then started posting things that have nothing to do with the content of the video.
