Flywheel shape
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high specific energy (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The energy efficiency (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 kWh to 1… Webk = inertial constant - depends on the shape of the flywheel. m = mass of flywheel (kg, lb m) r = radius (m, ft) Inertial constants of some common types of flywheels. wheel loaded …
