- 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 ;-)
