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.
