Exactly what time, the link you added just sends me to the beginning and I didn't want to watch it all the way through again lol

Piston rings don't have to move under their own force though. You can start up the engine and it'll break loose. The vanes use a spring, if it's jammed up enough to oppose the spring then you have to take the engine out/apart to fix the problem. I'm not sure what other problems might arise from not fixing that issue in time.

Good point about the vanes jamming in their sleeves potentially being a problem at startup. As RPM increases, centrifugal force will make it harder to retract the vanes, so they might need some kind of powered actuation beyond just a passive spring.

If you go to like 15.05 he talks about how the vanes do make contact with the walls currently, so emissions and scaring like what happens in wankels is probably an issue. The Rolls Royce thing is more theoretical right now, sounds expensive, maybe doable IDK 🤷🏻.

I kind of hate how this guy "hangs a lantern" on all the flaws of the design. I appreciate the enthusiasm for the engineering but, don't act like it's perfect and everyone else is dumb for not thinking the same lol.
