    Flywheel Power Generation

    Are flywheel generators capable of producing more power than it takes to keep them spinning?

    No.... energy cannot be created from nothing.

    Flywheels are like batteries. They store energy but do not produce it.

    A flywheel is a very heavy wheel, formerly a large spoked wheel with a heavy metal rim but now more commonly made from a carbon-fiber composite material, with a smaller cylindrical form that is only about a quarter as heavy. In both cases the principle is the same – it needs significant force to set the wheel turning, and the same to stop it from spinning. In other words, it has high angular momentum
