- ridgeguy 9y agoIn-ground gives additional protection, but things can still get away. Beacon Power is AFAICT the leader in deployed flywheel electrical energy storage. Their units are all underground. One of their failures dislodged a heavy concrete and steel lid on the unit [1]. Part of their emergency shutdown routine is a water dump into the flywheel chamber to dissipate energy. The water flashed to steam and blew a multi-ton lid partly off the unit. The spinning rotor did not escape, so all was well. More about Beacon Power technology: [2].
