Although my little fun fact doesn't apply to THIS flywheel generator, I recently learned, that flywheel generators are used all over Europe to stabilise the Continental Europe Synchronous Area: They are constantly kept spinning and because of their inertia they level any voltage drops and peaks they encounter. Learning this blew my mind because I never would've thought that such a simple technology was used to stabilise our electricity grid.
