With the levels of non-renewable energy dwindling every day, energy conservation is the need of the hour with this objective, a speed braker power generation system is designed and fabricated in this work. Law of conservation of energy formed the basis for this work. When a vehicle moves on the road, a lot of energy is wasted, thus by intelligent systems one can render it back as a useful energy. The proposed system looks like a speed braker across the road, which is utilized to generate electric power by using the motion of the vehicle. This speed breaker will be differentiated from actual speed braker. This will be a safer system and there is no needs for reduce the speed, while vehicle crossing the system. The design and fabrication phase of this work included, the design of components, such as spur gear, deep grove ball bearing, tension spring, iron plate, coupling, guiding shaft and hanger. The system fabricated successfully to complete the working model and also results are obtained.
