I stumbled upon this a few months ago on YouTube, and now they've just released a new video which is pretty interesting. I was wondering what you guys thought of this idea. Bit of a pain to wrap your mind around the concept, but it's quite elegant, in a way.

to many moving parts :P

And people think 4 strokes are complicated. :o
Imagine that mass spinning on your bike going up a ramp. :-X

Per unit displacement, rotating mass is dramatically less than a four-stroke, or at least so they say. The only thing complicated about this is the number of pistons, but there are far fewer moving parts than a four-stroke of similar displacement, because as in two-strokes and Wankels, everything is controlled by ports rather than valves.

There was a British truck manufacturer that back in the 50's used a sleeve valve reciprocating gas engine.
