Regenerative brake
A regenerative brake is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a 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 brakes and therefore wasted. In addition to improving the overall efficiency of the vehicle, regeneration can also greatly extend the life of the braking system as its parts do not wear as quickly.
