This research proposes a novel micro-renewable energy harvesting system named Highway Air Harvester (HAH), which captures the high-speed airflow generated by moving vehicles and converts it into usable electrical energy via strategically placed micro wind turbines. As traffic increases globally, vast kinetic energy from vehicle-induced wind remains unutilized. This study presents the system design, aerodynamic analysis, prototype development, mathematical modelling, and performance evaluation of the Highway Air Harvester. The results indicate that airflow velocity increases by up to 200–350% in high-traffic zones, enabling sufficient turbine rotation to power street lighting, sensors, and IoT devices. The proposed system is low-cost, eco-friendly, and scalable for smart city infrastructure.
