Hey that's sort of neat. I didn't know flywheels were really being deployed anywhere.

I bet the fail state would be a proper disaster though. Centrifuge accidents are no laughing matter!

Quite correct. Even if the outer casing is enough to contain the rotor, that is still 32 kilowatt hours of kinetic energy that goes somewhere. They're saying they saved money by putting it above ground, that means if potentially the casing fails you have little shards of metal going out with great energy in every direction.

Yea I would have hoped that it’s basically regulated that any sufficiently large fly wheel needs to be underground.
