You coul dif you knew how much energy it takes to keep the flywheel rotating which is my point of how silly it is to consider a flywheel as energy storage. You have to keep pumping energy into it to keep it running. Just like your car when you hit cruising speed, you do not turn off the engine, only decrease power from acceleration to cruise. You are still burning fuel.
That is OK if you have say a Data center and need a few minutes to bring the generator only line and could careless how much power the Flywheel uses in standby mode. Every second that Flywheel spins in standby is draining efficiency to almost nothing. In a solar system you do not have that extra energy to spare 24 hours a day, then the dang sun sets and your flywheel comes to s stop, and you have to waste all that energy spoiling it up again to repeat daily. That is insane use of the technology.
