I had no idea this type of valve was a thing. Interesting to learn a little about. Maybe something like this would make electrically controlled variable timing more viable and thus improve the efficiency of ICEs?

Known a few people with rotary engines

They are better, but I know they cost more upfront, and I'm fairly certain maintenance becomes pretty expensive.

But if you want a rotary engine, there's a couple options.

Mazada RX8 is the most common I think in America, just good luck finding a non dealer that will work on one.

That's not what the post is about, it's about rotary valves. I'd never heard of them before watching the video, but it sounds like they don't exist in any production cars.

Rotary valves are more present in the musical instrument world, where they are used on French horns, some trombones, and some tubas.

On the topic of unconventional valves in automotive engines, I'd recommend taking a look at Koenigsegg's Freevalve technology.
