That is really interesting, thanks for explaining it.
I want to ask then, based on other comments, that size can greatly improve the amount stored. So wouldn't a larger safer flywheel work in many places?
Also, my thought on the water as a solid, consider a steel wheel where instead of steel all the way through, put a liquid inside of a cavity. Since water doesn't compress, it would essentially be part of the same wheel, only safer in a collision? (arm-chair engineer)
I enjoy reading comments like yours so I can move on/let go of my from my silly pet ideas. :)

Well, consider that solid steel is considered too weak for a modern flywheel. So that questions why you'd be removing steel instead of adding more of it.
Modern flywheels spin really, really, really fast. Again, fast enough that modern solid steel is too weak. Newer composite materials are superior, but still need to be designed for maximum structural integrity.
Once a flywheel spins fast enough, it literally rips itself apart due to centrifugal forces. Any "cavity" weakens the structure and will break sooner.
