Tech aside..
That AI-created video was mostly unwatchable. It bounces all over the place, missing information, glamorous generalize statements with no purpose, etc. The engine might have been AI designed as well for all we know. I might be missing something here.

Basically it's a gear type arraignment between two cylinders where tooth interaction creates a micro combustion chamber while it expands and creates an even longer expanding 'cylinder'. ~ 50-95% on the flame front is not pushing on the parts which are supposed to make it move. The intake and spark plug are all crammed into the wedge and the air has to make a sharp turn there. Only more boost could create more power because there's no room for bigger valves. Think huge wasted surface seal-sweep area and path. Way too much quench. The c/c appears to be kinda like a long stroke engine cylinder with a short rod where the cylinder doesn't get more than a tenth up to the top. I'm not sure how it improves over existing designs. I hope it works as advertised and improves society blah blah but remain skeptical.

I've seen a similar experimental designs which were similar, such as a giant gear surrounded by a ring of miniature Wankles acting on it.
These designs are really neat but when put into practical application there are all sorts of additional problems which will pop up.
I love the efforts though.
Someday there will be a major breakthrough.

There was another recent story about a teen who thought up replacing brake rotors with motors to turn any gas auto into a hybrid. Big splash. Cool idea. Except hub motors have been around for more than a hundred years already. A better location to add a motor would be at the flywheel, or driveshaft/CVs, or as a combo alternator-starter-motor on the crank. And adding extra un-sprung weight at the wheels really screws up performance. Plus there is all that wiring to the extra batteries in the spare tire spot. And how to activate the system per driver input. Extra exposure to vibration water etc.
