- Wouldn't you expect that a containment failure in one would quickly
- cause all the others to fail too? Wouldn't 20 flywheels in general be
- more likely to have one failure than one flywheel would, assuming the
- same levels of margin were engineered into both designs? (just as a
- trivial example, if you use electro-magnetic bearings that's 20 times
- as many connectors which could fail. There's also 20 times as many
- vacuum valves which could fail.)

- Not only that, but a spokesperson (president of the company, actually)
- who is obviously intentionally using misleading words like "fluff".
- (his success rate at deceiving the public must be phenomenal
- considering how many USENET english majors he's hoodwinked)
