(...) Thanks for that addition Derek. One issue with high angular velocities is stalling. To get the high RPM you tend to need lots of gearing, and starting out can be a pig. Ideally, a high speed flywheel behind a CVT should work great, but I (...) (18 years ago, 24-Oct-06, to lugnet.org.ca.rtltoronto)

(...) Angular momentum plays a big role in flywheel design as well. So you can bring velocity into it. You can add a small, light, fast flywheel, and a large, heavy, slow flywheel to your options. Also flywheels don't have to be circular and they (...) (18 years ago, 24-Oct-06, to lugnet.org.ca.rtltoronto)

If you want the math for the moment of inertia of a rotating object, here is the wikipedia article: (URL) (hehe) Bottom line is a flywheel is more effective when its inertia is larger (mass is further from the center of (...)
