Cool. Wonder if the'll stick one in a reborn Cosworth.

Actually pretty familiar with the company and concept. Built a simplified version with some CAD software cause I wanted to get a better grip on the motion(simulation). The "coin flip" motion is interesting, but the realization that the contrarotation of the assembly comes from planetary gears hit like a ton of bricks (obvious when you think about it).

Pretty cool upside to the design, but believe the applications it is currently being used is limited.

It has sealing and lubrication problems with the head plate and the cylinders. Worse than a Wankel. Looks good for a short test, but put it in a car and put 50,000 miles on it and pass emissions. Won't beat a regular IC engine.

negligible when used in a torpedo.

How do you cool it? Sealing and reseal rotating water jackets surrounding the cylinders?
