    Flywheels are for grid level storage, which is the primary problem holding back renewable sustainables.

    Still a lot less effective than just building a pellet reactor.

      I think they're mainly for short term regulatory storage, since they can be charged and discharged quickly. I don't think anyone wants to store an entire city's power in flywheels.
