Energy Harvesting from Moving Vehicles on Highways

Various technologies have been developed to harness energy sources present on roadways, such as electromagnetism, and photovoltaic modules. The focus on developing and implementing sustainable renewable energy systems is increasing due to the high emissions resulting from the use of natural fossil fuels. Wind turbines are commonly utilized to convert wind energy into electricity, with potential for harvesting wind energy generated by traffic along highways. This study analyses the aerodynamic impact of traffic on highways to estimate the energy generation potential through computational fluid dynamics (CFD) analysis.[1] The feasibility of using this energy to power highway lighting systems is also explored. The paper reviews existing technologies for energy harvesting from roadways, categorizing them based on transduction methods and system architecture. Commercial systems available for energy scavenging from roadways are also surveyed, with comparative analyses provided to identify promising solutions for developing self-sustainable smart roads in the future. As and when the vehicles pass on the road a trail of wind is generated. With the help of VAWT energy is generated from this trail of wind and stored in the battery. [2]
