I'll agree on this point.

Yes they have been built and they presumably have been tested to
failure.  However, I read it in a newspaper report which I have since
tossed and cannot provide conclusive references.  Either the flywheel
"con"s are not aware of the report or they dispute it.

This is the main point of dispute.  "Pro"s like me believe the testing
that showed failure dissipating into fluff.  "Con"s believe that
failure means BOOM.  Without a controlled test, its all speculative,
regardless of the quality of analysis we apply.

A clarification, as Carl surmised, is that I really don't believe in
EV per se, but rather in using the flywheel as a power "capacitor" in
between a small, efficient IC engine and the driveshaft.  By storing
mechanical energy in a FW over a large time, we can dump it in 100hp
bursts for acceleration.
