You seem to be missing something here: The amount of energy you'd have to store in a flywheel to make it work as a "battery" for an EV is MANY times more than the energy required to accelerate a 50's Caddy to 100 mph. Further, the flywheel's presumably going to be in something intended to contain it in the event of a catastrophic failure. If that container fails, it will nearly instantaneously release much of the energy that had been stored in the flywheel. In other words: Release a lot of energy inside a pressure vessel, and allow that vessel to fail. BOOM! Really? =Take a loaded tractor-trailer with bad brakes. Put it down a mountain =road. Send it up the "Failed Brakes" escape road. Did it go BOOM? Try picking a vaguely valid analogy next time, will you? -------------------------------------------------------------------------------- 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.
