New engine design

I don't know enough about engines to say how this is different from the rotaries Mazda tried using, but I think those had some serious issues with temperature gradients that ended up warping the whole engine block. This looks like it might have the same issue where cold intake air is always on one side of the rotary lobe, and hot exhaust air is always on the other side of the lobe. When a chunk of metal is constantly heated on one side which being cooled on the other, stuff breaks.

Again, I know very little about this about if thing and the people designing and building their own engine probably have some clue about it, so I'm probably just wrong. But I would like to know how they address the differences between their engine and the other well known rotary engine with it's well known issues.
 
I know that Wankels had problems with the seals. It looks like the seals on this engine are not as crucial due to the shape of the rotor.

Yeah that's true, no apex seals here, but looks like more metal on metal surface area which would require more oil getting burned, which was another problem with the Wankels, but less so with chainsaws! Could this be the 4 stroke engine that runs on mixed gas?
 
They make a diesel version also. I fundamentally like the rotor concept, as opposed to pistons flying back and forth, plus 3 ignition events every rotation.
 
Good Question. I don't know the answer. I suppose it depends on the mass of the rotor.
