Then the breaking flywheel may just cause the housing |to turn faster. The flywheel particle momentum is lost with a less |forceful impact (prolonged impact) because the turning housing is moving at |a lower speed relative to the flywheel particles (which in turn move at a |lower speed relative to the housing). It's a flywheel inside a flywheel inside |a flywheel. Unless the vessel is spinning at a significant fraction of the rotors velocity, there will not be time to transfer a significant amount of energy to it, before the shock waves tear it apart. Then again if it were spinning that fast, it would already be under a lot of stress and would need less of a shock to cause a catastrophic failure. Sounds like your working on the idea of multiple flywheels, so that each wheel needs to carry less kinetic energy. -- Mob rule doesn't become any prettier, just because the mob start to call itself a government.
