Energy Harvesting from Speed Breakers is an innovative project designed to generate electricity from the vertical motion of vehicles passing over speed breakers. When a vehicle moves across the specially designed speed breaker, the downward motion is transferred to a mechanical linkage system (such as a rack-and-pinion or lever mechanism). This mechanical energy drives a rotating shaft connected to a dynamo/alternator, which converts it into electrical energy.

The generated electricity is stored in a battery through a charge controller, and can be used to power street lights, traffic signals, or charge small electronic devices. This system is highly beneficial for busy highways, toll booths, parking areas, and city roads, where vehicle density is high.

Parts Used:

1. Speed Breaker Assembly (Spring or Hydraulic Based) – Transfers vehicle load into mechanical motion.
2. Rack & Pinion / Lever Mechanism – Converts vertical motion into rotary motion.
3. Shaft with Bearings – Supports and transfers rotation.
4. Dynamo / Alternator – Converts mechanical energy into electricity.
5. Rechargeable Battery – Stores generated electricity.
6. Charge Controller – Regulates voltage and current for safe charging.
7. Inverter (Optional) – Converts DC to AC for larger applications.
8. Output Load (LED Street Light / Charger / Traffic Signal) – Utilizes the harvested energy.
