From what I remember, if these fly wheels are housed in vacuum and stabilized using a magnetic field, they should be able to spin almost indefinitely. Sure it takes a lot more resources, but I am surprised that this company hasn’t looked into developing more effective means of storing power than just air exposed fly wheels and ball bearings.

CO2 can be collected from the air by wind, wave and geothermal power and shipped globally to flywheel power transmitters
