anyone know about this engine

HAPPY EASTER all; I can across this website http://www.grossishop.com/ and was wondering if anyone knows anything about these motors. Check out their YouTube on their assembly and how they use magnets for the rotory disk. I've never seen this before and not sure how it works. Mario

Well it looks awfully pretty.

They're definately buggy engines. With that crank, it would be difficult at best to use in a boat.
