This guy is correct.
As an interesting side light, the largest forging ever made is
the largest flywheel ever that stores energy at MIT for the
ALCATORC-MOD fusion reactor. It takes like 500 hp all night to spin it up,
and 3 seconds to stop when the switch is flipped.
Yeah, megajoules, many of them. If there was a quake when the thing
was spinning, it would remove a large section of Cambridge.
Its surface speed is just below the speed of sound, and it weighs like
a very large steam locomotive ; and its right next to the FISSION
reactor..... they know there is no way to stop it if there is a quake,
so its just in a simple flimsy building.
