Vertical Axis Highway Wind Turbine

Vertical Axis Highway Wind Turbine

Project Overview

The Vertical Axis Highway Wind Turbine (VAHWT) is an innovative renewable energy system designed to generate electricity from wind energy produced by moving vehicles on highways. Unlike conventional wind turbines, this system uses a vertical axis design, allowing it to operate efficiently regardless of wind direction.

The project aims to harvest otherwise wasted kinetic energy from high-speed traffic and convert it into usable electrical power for highway lighting, signals, and nearby infrastructure.

Working Principle

The system works on the principle of aerodynamic drag and lift generated by airflow from moving vehicles.

1. Vehicles moving on highways create strong air turbulence.

2. This airflow strikes the vertical axis wind turbine blades.

3. The blades rotate around a vertical shaft, independent of wind direction.

4. The rotating shaft drives a generator.

5. Mechanical energy is converted into electrical energy.

6. Generated electricity is regulated and stored in a battery system.

7. Power can be used directly or supplied to loads such as street lights, sensors, or charging units.
