While a (BJT) can be simplistically thought of as two diodes with a shared terminal (anode for the PNP variety), the transistor polarity is usually expressed based on the prevalence of in the parts of the device: for the regions where the charge flow is primarily due to the electrons (free due to the presence of ), and for the regions where the flow is mostly due to (available spaces for additional electrons.

First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass.OverviewFlywheel energy storage (FES) works by spinning a rotor () and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced a. .
A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
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.
