They've been proving it for over two years, so it's not far off development.
Excellent projected improvements, including recovering energy by engine braking.
One can only hope it goes further than the 1970s Ozzie Sarich engine that was supposed to do wonders. It ended up in the Powerhouse museum.

Great to see how modern materials and computor control can bring 100 year old ideas to reality.
Re the Sarich Engine; again the materials and technology of the time didn't make any great improvements over the piston/poppet valve engine, but Ralph went on to develope the injection system that now is able to make a two stroke run cleaner than a four stroke. The last I saw of it was running in a three cylinder two stroke in a Camira wagon in Detroit.

Although the Sarich injection systems seems to be OK the orbital engine never was. I heard Sarich give a talk about it and even a couple of years into the hype associated with it one had never been run to max rpm.
This individual valve actuation opens up all sorts of options.
