Abstract: Energy plays a crucial role in our daily lives, but with a rising population and finite natural resources, finding sustainable solutions is essential. Wind energy is a renewable and cost-effective source that can significantly contribute to conserving non-renewable resources. Although wind power has been harnessed for centuries, it has only recently gained prominence in global energy solutions.
This project focuses on utilizing wind energy through a vertical axis wind turbine (VAWT), specifically designed to capture airflow generated by moving vehicles on highways. The VAWT, strategically positioned on highway dividers, features aerofoil-shaped blades that are lightweight yet highly rigid, enabling efficient wind capture. The turbine's blades rotate due to the passing vehicle-induced airflow, transmitting mechanical energy to the generator, which achieves a maximum rotational speed of 500 rpm, generating up to 14.5 volts.
The generated electricity is stored in a battery, ensuring reliable power supply for various applications such as road lamps and other essential infrastructure needs. By harnessing wind energy in high-traffic areas, this innovative approach contributes to sustainable energy solutions while maximizing the efficiency of natural resources.
