Abstract:
Energy Scarcity And Depletion Of Non-renewable Fossil Fuels Are Two Of The Most Pressing Challenges Facing Modern Civilization. This Paper Proposes And Analyses A Novel, Low-cost Mechanism For Harvesting Electrical Energy From The Kinetic Energy Dissipated By Vehicles Crossing Road Speed Breakers. The Proposed System — The Power Hump — Integrates A Rack-and-pinion Mechanism Beneath A Spring-loaded Speed Breaker Plate. Vehicular Pressure Drives The Rack Downward, Rotating A Pinion Gear. Through A Compound Gear Train (1:5 Speed Ratio) And Belt Drive, Rotational Motion Is Transmitted To A DC Generator Capable Of Generating Up To 70 V. Electricity Is Stored In A 12 V Rechargeable Battery For Road And Street Lighting. A CATIA V5 Three-dimensional CAD Model Has Been Developed To Validate The Mechanical Design. Experimental Results Demonstrate Stable Voltage And Current Output Across Varying Vehicle Loads. A Single Power Hump Unit Can Generate Approximately 3.5 KWh Per Day At A Moderately Busy Intersection, Sufficient To Power 8–10 LED Street Lamps Throughout The Night.
