Step 1. Some special vehicles have spinning disks (flywheels) to store energy while they roll downhill. They use that stored energy to lift themselves uphill later on. Their flywheels have relatively small rotational masses but spin at enormous angular speeds. How would a flywheel''s kinetic energy change if its rotational mass were 3 times ...

The following equation shows the energy of a flywheel [1] : Erotation = Iω2 2 E r o t a t i o n = I ω 2 2 where, • Erotation E r o t a t i o n is the energy stored in the rotational momentum ( Joules, J) • I I is the object''s moment of inertia (kilogram * meters 2, kgm 2 ) • ω ω is the rotational speed (radians per second, rad/s) The ...

The issue with a flywheel is that you have friction while you are storing energy. The more energy you store, the higher loss rate, assuming normal bearing losses. With hydro, you have friction when you try to use the energy. You can store hydro as long as you want, simply shut the valve.

Function of Flywheel. A flywheel is a heavy wheel attached to a rotating shaft so as to smooth out the delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use. Flywheels are found in almost all types of automobiles ...

Share this post. Flywheel energy storage systems (FESS) are a great way to store and use energy. They work by spinning a wheel really fast to store energy, and then slowing it down to release that energy when needed. FESS are perfect for keeping the power grid steady, providing backup power and supporting renewable energy sources.

Physics questions and answers. Energy storage devices that use spinning flywheels to store energy are starting to become available. To store as much energy as possible, it is important that the flywheel spin as fast as possible. Unfortunately, if it spins too fast, internal stresses in the flywheel cause it to come apart catastrophically.
