Researchers at ETH Zürich are developing a pneumatic hybrid engine—an internal combustion engine connected to a compressed air tank instead of a battery system. The compressed air supply also allows extreme downsizing. Downsizing the engine in this instance halves the number of cylinders from four to two. Rüegg / ETH Zurich.

So we have a clutch that connects to a huge flywheel. The flywheel is downsized to give a continuum between shift of gears, else unlike a ICE engine, when you take your leg off the pedal, the motor goes zero torque when you are re-engaging gears. The only other product that they have for comparison is the Sonalika tractor.
