Looks like the inside of a Sanden A/C compressor to me

Duke first used their engine in a car in 1993, 23 years later there's not much progress.

How does it seal the spinning block to the stationary head?

Most of these alternative internal combustion engine designs have tricky sealing problems, one of the reasons they tend to get nowhere.

Some other different engines here - http://www.locostbuilders.co.uk/viewthread.php?tid=200120
I oarticukarly like the CEM engine, as already said, needs something novel in the sealing department, also has a lot of rotating mass, not good for
throttle response.

It looks overly complicated to my untrained eyes. Particularly when straight 4 bangers are so cheap and easy to use.
I drove a colleagues Mazda RX8 with the rotary engine. It was quick enough, but really didn't have the whoosh factor I expected it to have. I
like the fact many have gone bang and people are playing with fitting other engines. There's a guy on here fitting an Audi 4 pot petrol turbo
to one and it looks a good project to me.

Over 20 years ago I saw a prototype Aero engine in the Bristol Industrial Museum using the same principle.
From memory it had 7 cylinders and sleeve valves.
It didn't go into production.
Obviously I remembered it and thought it worthy of development.
