'Constant-frequency uninterruptible power supply using flywheel energy storage'

I'll let you know when I finish the steel flywheel I am making and test it out. If possible, i am going to run up the flywheel until it explodes, so I know a relatively safe speed to be running flywheels at in the future.

Flywheel is used to store Rotational Energy.

The most familiar energy storage device is a battery used for electrical power supply. Energy can also be stored in a flywheel, in a spring (wristwatches, in earlier decades, used to be powered by a mainspring that you had to wind up by hand, rather than by batteries) and various other things.
