I was thinking same as Raymond, that the moving parts in an OHV engine are
a lot of both the energy and manufacturing inefficiency of a traditional
engine. I don't think a belt or anything else would work though, and what's
an extra gear or two? Transmissions are full of them, no problem really.
The configuration shown in the video is probably not going to be the end of
the story if this design gets beyond the test bed stage and the best
mechanical and manufacturing minds start pondering it. The only concession
to precision control mentioned in the video seems to be the boost, so I am
not sure variable piston relationships would be needed if that is so.

Emissions? Don't know but it seems like 45% efficiency would be a great
place to start from.
