'More' deployment?

Show me a production car that uses it now.

And no- I don't mean a small shop selling a couple hundred / few thousand..

There have been prototype for decades..

Then you understand the state-of-the-art and its business relevance.

Probably with the advent of routine production EVs, prototype investors probably backed away since anything associated with optimizing the internal combustion engine at that level is moot.
