- You seem to be missing something here: The amount of energy you'd have to
- store in a flywheel to make it work as a "battery" for an EV is MANY times more
- than the energy required to accelerate a 50's Caddy to 100 mph. Further, the
- flywheel's presumably going to be in something intended to contain it in the
- event of a catastrophic failure. If that container fails, it will nearly
- instantaneously release much of the energy that had been stored in the
- flywheel. In other words: Release a lot of energy inside a pressure vessel,
- and allow that vessel to fail. BOOM! Really?

- Try picking a vaguely valid analogy next time, will you?
