Abstract: Title: ENERGY HARVESTING FROM VEHICLE-INDUCED AIRFLOW ON 5 HIGHWAYS FOR SUSTAINABLE POWER GENERATION This invention relates to an energy harvesting from vehicle-induced airflow on highways for sustainable power generation. It typically includes a Hybrid VAWT Blades (1), a Turbine Shaft & Bearings (2), a Support Frame & Mounting Stand (3), a Permanent Magnet Synchronous Generator (4), a Diode Rectifier Circuit (5), a 10 Maximum Power Point Tracking Controller (6), a Voltage & Current Regulators (7), a Lithium-Ion Battery Bank (8), a Solar PV Panel (9), an loT Sensor Suite (10), a Cloud Platform & Microcontroller (11), and an Automated Shutdown (12). The advantage of this system is that it converts otherwise wasted, vehicle-induced turbulent airflow into clean, low-cost electrical energy to power roadside infrastructure without altering 15 existing highway space. The applications of this system include powering highway LED streetlights, electronic traffic signage, toll plaza operations, emergency call boxes, and roadside loT environmental monitoring sensors.
