Interesting , but the principal of "waffle plate" drive pistons is not new.
personally, I don't like the idea of all those pistons and con rods etc rotating around the main shaft !
That is a huge amount of rotating mass.
and the hinge bearing on the piston carrier looks to be a complex, heavily loaded, assembly.
the Wankle is a much simpler , elegant, lightweight compact, design with only 3 moving parts......but horribly inefficient.
its a waste of time , money, and resources, developing any new IC engine....
...The future is Electric drive !
That was my thought too. IC is so 20thC

I thought most piston ICE's could be adapted to run on any of those fuels also !
( wasn't there a Toyota ute in the last "green car run" from Darwin to Adelaide , running on a mixture of salt water and sump oil ! )
Yep, Duke (Axial) Engines are an old but proven design....
By the way, not a 'Waffle Plate' but a 'Swash Plate'...
