As a mechanical engineer, he explains his concern is with the force that builds up in the rotating flywheel.

The use and role of flywheel energy storage systems

Print this page. Flywheels, in short, are machines that store kinetic energy in a rotating mass. The flywheel operates via a "flywheel effect"whereby its rotation is maintained via its own inertia [1]. Although ancient science did not understand the mechanics of flywheels, ancient engineers were able to develop spindle whorls (by 6000 BC ...

Flywheel Energy Storage | Working & Applications

A flywheel energy storage can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. They work by spinning up a heavy disk or rotor to high speeds and then tapping that rotational energy to discharge high power bursts of electricity. It is difficult to use flywheels to store energy for ...
