In the 1950s, flywheel-powered buses, known as gyrobuses, were used in Yverdon (Switzerland) and Ghent (Belgium) and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh
Such flywheels can come up to speed in a matter of minutes – reaching their energy capacity much more quickly than some other forms of storage. [5] A typical system consists of a
The amount of energy stored in a flywheel is proportional to the square of its rotational speed; hence, higher speeds lead to significantly increased energy storage capacity.

A flywheel energy storage system is a mechanical device used to store energy through rotational motion. When excess electricity is available, it is used to accelerate a flywheel to a very high speed.
The flywheel system is designed for 364 watt-hours of energy storage at 60,000 rpm with a 9" diameter rim and a maximum tip speed of 700 m/sec. Figure 1: Flywheel energy storage

The amount of energy stored in a flywheel is proportional to the square of its rotational speed; hence, higher speeds lead to significantly increased energy storage capacity.
Equation 12 shows the stress developed in the spinning flywheel is proportional to the material density and the tip-speed. ω Thus, one cannot arbitrarily increase the speed without
An upper limit to the mechanical energy that can be stored by a flywheel arises due to the mechanical stresses in the flywheel itself. As the rotational speed of the flywheel increases the
