Yes but centrifugal forces on the simle “rotating fluid” equivalent are too strong and require a costly casing when compared to an equivalent solid flywheel. What they do is they use the rotating part as a pump to push the fluid up a vertical pressurized storage and the pressure there plus the potential energy of the fluid store the energy in a more manageable matter than having it all in the fluid speed
I remember seeing a device that used flywheels to “generate lift” and I couldn’t help but noticing it involved counterrotating units, meaning that where they approached each other they were both spinning the same direction (up or down, I don’t recall which). I thought, “I bet this doesn’t work in a vacuum chamber”.
Later I remembered rotor ships. He essentially stood a complex one on its ear, and made some math errors that backed up his discovery.
Oh yes, that's true! In Europe they are also used when there is not enough space for purely front loaders... nevertheless they still spin around horizontal axis.
Not much new here, just scaling down the production of centripetal force.
