Looks like a good idea. I was thinking small servo motor but it would be hard for one to operate with the strength and frequency required.

Yes, it's very interesting... 
but he didn't mention HOW MUCH AIR is required, nor the size of the 'air compressor' that is necessary to be carried in order to perform his 'magic'.
Watching and listening the video, took me back to 1974, when I received my BSE degree, and began post graduate study. My degree was in Engineering, but with EE specialization, and I had strong interest in mechanical from my 'car hobby'. My controls professor was a mechanical engineer from Purdue, who had world renown in the control theory field, who convinced me to do an 'automated inverted pendulum balancer' for my senior design project, which turned into what should have been a Masters thesis on it's own. (I rec 3 sh credit though). When I graduated and began graduate school, this professor who was also a car nut (who drove a '66 Mustang and who I helped find a '65 Shelby GT 350) pushed me to design a 'cam-less engine', using solenoids to actuate the valves (this was before the time of the Cadillac 4/6/8 design as I recall). It was very interesting to me, but there was No way I was going to undertake that, given what I'd had to do for my 3 hr senior design project!!
I've followed the related developments the past 20 yrs or so, and there's been progress, but there was NO way in 1974-75 time frame that was going to happen in a 'practical' engine!!
