So the link to our ongoing debate/discussion would be that a heavier flywheel like those big ones in the video store more power or store the power longer? Than say a lighter flywheel, completely disregarding what autoteach had explained earlier about the distance of mass to center of rotation?? ???
What auto tech said still applies. Basically the farther you get from the center line the higher the velocity at a given rpm. Put the mass where the velocity is higher and you will have more inertia. Notice in the video how the flywheels are constructed, they are both massive and have a large diameter with most of the mass at the edge of the wheel. using the same amount of material they could have made the flywheel more compact (smaller dia but thicker) however it would be far less effective.
