I've come to the conclusion over the years that if the press release or
website concentrates on the applications rather than the technology itself,
and the tech has not yet been clearly demonstrated, it's vapor. Sure, high
energy density flywheels would be very useful, this has been known for a
long long time- but nothing on their site shows that they know how to
*build* such things.

I believe in hardware- I've been testing a complete rocket engine and its
ignition system all week, and the functional hardware is essential to
making real progress. Talk is cheap, action is difficult.
