Also, the one that shoots out flames paints a picture similar to how a synchrotron behaves, shooting out X-rays into the beamlines as the electron bunches move around.
Upon looking into it closer, the synchrotron is a bit of a mixture of those two concepts - the source loop (booster ring) that is fed by the linear accelerator, and then the larger loop (storage room) that feeds X-rays the beamlines. Of course, many details differ, but still it is interesting to notice the similarities !
There could be some use for it in detonation front research. Rotating detonation engines biggest issue is keeping the detonation front alive and active.
Tbh, it's what I enjoy about his videos in particular. He will run into or be shown a relatively mundane thing, but then dig into just for the sake of his (and our) curiosity. It's low-stakes science that still cares enough to dig past the surface layer of discovery
He also does a fairly good job citing his sources, which is nice to see in a popular content creator.
