- Arrogant prating becomes you, sweetie. Nice to see a preacher here 'bouts.

- The largest difference, in any case, between the "exploding gasoline"
- scenarios and the broken flywheel is not the energy but the instantaneous
- power - probably between 8 and 10 orders, depending.

- The energy dissipation within the volume of the container tends to zero
- for a vacuum; most of it occurs at the container walls. If one could
- spread out the volume of energy dissipation, the chances of containment
- are concomitantly higher. Despite this fact, I don't *really* think foam
- is going to do it.
