Well, unfortunately, there's that nasty old law of conservation of energy again: You're trying to store a certain amount of energy. That energy has to go someplace. Now, you can spin a little flywheel up *REAL* fast, or you can use a somewhat larger flywheel, which doesn't have to be spun up quite so fast. Or you could have your flywheels within flywheels scenario. First of all, such a setup would require much higher precision in the implementation of the system. Second, what if it were the rotating container that failed? That'd be likely to cause a failure of the internal flywheel, and you still get a rather large boom. -------------------------------------------------------------------------------- Carl J Lydick | INTERnet: CARL@SOL1.GPS.CALTECH.EDU | NSI/HEPnet: SOL1::CARL Disclaimer: Hey, I understand VAXen and VMS. That's what I get paid for. My understanding of astronomy is purely at the amateur level (or below). So unless what I'm saying is directly related to VAX/VMS, don't hold me or my organization responsible for it. If it IS related to VAX/VMS, you can try to hold me responsible for it, but my organization had nothing to do with it.
