FlywheelRelated: A flywheel can store recovered braking energy for later acceleration.
Hybrid electric vehicleRelated: Hybrid vehicles use it to recharge the battery while slowing down.
BusRelated: Electric and hybrid buses can recover energy during repeated stops.
SupercapacitorRelated: Supercapacitors can absorb brief, high-power bursts of braking energy.
Endurance racingRelated: Hybrid endurance cars can recover braking energy for later propulsion.
Hybrid vehicleRelated: It recovers energy that conventional brakes would dissipate as heat.
Bicycle brakeCompared with: It recovers energy instead of dissipating all braking energy as heat.
