It would be very interesting to see.

Sorry to hijack the thread, but this video on the air engines is really misleading. Not once do they mention where one fills their tank with compressed air -- it's insinuated one merely goes to any compressor but 150 Bar of pressure takes a significant energy input and specialized equipment. I'm sure the efficiency is close to that of an electric vehicle, but you won't get any of that from the video, just a whole lot of hype.
