That's really cool. It's neat to see how they are thinking outside the box for the next generation of engines.

This is not a new technology by any means. This design configuration has been used in hydraulic motors and pumps for decades! Interesting that someone thought it applicable to internal combustion engines. A down side that I can see is excessive rotating/articulating mass...as in what is called a swash plate in a hydraulic pump or motor.....in other words, the device the con rods would be connected to. In my opinion, for what ever that's worth, will it work? Sure! Just one old guys thoughts.

It does not show the critical seal between the rotating cylinders and the fixed plate with the intake and combustion chambers. I think it would be the weak link unless some new clever technique is devised.
