- But how hot would this "cotton" be? You're dumping what is presumably
- the equivalent of several gallons of gasoline's worth of energy.
- That's a very large amount of energy.
-
- After all, a Fuel-Air-Explosive is nothing more than some hot gas...
-
- Gasoline powered automobiles don't usually explode on impact despite
- what you see in the movies. Flywheel powered vehicles seem a lot more
- risky to me.
-
- I hope they do lots of crash tests before unleashing such a dangerous
- technology on the unsuspecting public.

- Can you imagine the bumper stickers:
