Greetings. (With all this BS and the confused/stunned/FUBAR folks trying their hand at interperting it, I thought I'd add to this mess) Ok, say we have a nice big flywheel. Yes, if it fails we get a nice big BOOM... lots of heat, plasma, you name it... flying your way. Also, you have to contend with the gyroscopic effect that this thing will produce in any vehicle that uses it... the magnetic bearings better be good, strong - and, as Mr. Murphy is whispering in my ear - DAMN reliable... Understood. Fine. Ok. So, what can you typical GM engineer do to pass Fed tests in the design of a car/auto/bus/whatever that uses this flywheel? Well, first off, it better pass the 5mph crash test without vaporizing the prototype & all the observers. This would be a Bad Thing(tm). Second, it should have minimal gyro effect on the handling of the car - we want this thing to sell. I guess this may be partially improved with an array of flywheels instead of one MONSTER one. Third, in case the bearings DO fail, what's the effect? Well, you COULD mount the thing in a sort of deflector dish so that an explosion is not limited to a container but instead is rediated AWAY from the occupants - Anyone see that episode of the Twilight Zone about some guys that enter suspended animation in a cave and wake up in the future with the gold bar they hope will be worth a fortune only to kill each other and [MY POINT] a couple in a "futuristic" car noting that gold is "so worthless". Anyhow, if you saw that episode, take a look at the car. It looks very funky because its windows look like reflector dishes... Well, how about mounting the flywheel so that when it does [note:not IF] blow it blows literally "Sky High". A similar idea is in every military arsenal - I believe it's called a Claymore which is a directional anti-personel mine. Fourth, why mess with all these problems when we can just wait for that guy [what's his face] to prove that you can get all that energy out of copper wire [remember the abstract that was posted here?] Well, I figure that both are about as practical. Not to start another thread but Golly Gee, imagine what would happen if all those trillions of watts from that inch of wire were suddenly released all of a sudden? Gosh, can you imagine what would happen if that force failed in the McKenly deflector field generator? Good lord, there goes the town... [Ignore me, I'm catching up on sci.electronics after a 2 week vacation in the Florida Keys... and driving 24 hours [yawn]] Take care :-) P.S. What suprises me is that no one out there gets ticked off by all this crap and builds a scale model of a flywheel, cranks it up to 5k RPM, releases the magnetic bearings, and reports how many counts of murder they are charged with ;-) >------------------------------------------------------------------------------- >Carl J Lydick | INTERnet: CARL@SOL1.GPS.CALTECH.EDU | NSI/HEPnet: SOL1::CARL >Disclaimer: Hey, I understand VAXen and VMS.
