I don't know.. The rotary motion of a generator makes a lot of sense. When a coil of wire cuts across the magnetic lines of force, a voltage is generated in that coil. Doing this by rotation is smooth, doesn't cause undo wear or breakage so it is reliable, the clearance between the stator and rotor is easy to control (quality bearings and fitment) and the momentum helps keep output up as load is suddenly increased. The normal generator makes a decent flywheel when it isn't under load.
This thing lacks all of these features. It has combustion very near its coil. The gas spring must stop the movement or it is instantly trashed.
The upside- It is small and has fewer parts.
That's about it. In my opinion it will be a while before these replace the world's ubiquitous generators.

Thanks for posting this, I'd never seen one of these.
