- I'm not all that technically educated, so please clear something up for
- me:
-
- Everyone seems to be saying that the release of energy would be
- vitually instantaneous; and this instant release of energy would
- result in an explosion.
-
- When a flywheel is spinning, the largest amount of motion is in the
- same direction as the casing of flywheel. If the flywheel were to
- suddenly turn into "fluff", wouldn't the fluff continue to spin (or
- more accurately race around the inside of the housing) for some time
- within the housing and gradually lose it's energy (and velocity) to
- friction in heating up the housing?
-
- I don't see why any feasible casing for the flywheel wouldn't be
- reasonably polished so that there would be a relatively small amount of
- friction when contact arises.
-
- Wouldn't this tend to spread the energy release over a larger period
- of time? If so, wouldn't this reduce the possibility of an explosion
- and perhaps result in the unit gradually (relatively speaking!)
- melting down without an explosion?
-
- Am I missing something obvious?
