I *TOLD* you the propaganda would be effective. The answer to your question is: That flying piece of cotton will have approximately as much kinetic energy as was originally stored in the flywheel. That follows from the law of conservation of energy. Just because it's fluffy doesn't mean it's not dangerous, given that it's going fast enough. -------------------------------------------------------------------------------- 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.
