F1: Sebastian Vettel explaines KERS System

The German Red Bull Racing Team driver Sebastian Vettel (reigning champion of Formula 1) talks about the KERS System and the utility of the adjustable rear wing.

Kinetic Energy Recovery System (KERS) is a regenerative brake, an energy recovery mechanism which slows a vehicle by converting its kinetic energy into another form, which can be either used immediately or stored until needed. This contrasts with conventional braking systems, where the excess kinetic energy is converted to heat by friction in the brake linings and therefore wasted. The most common form of regenerative brake involves using an electric motor as an electric generator. In electric railways the generated electricity is fed back into the supply system, whereas in battery electric and hybrid electric vehicles, the energy is stored in a battery or bank of capacitors for later use. Energy may also be stored via pneumatics, hydraulics or the kinetic energy of a rotating flywheel.
