Vertical Axis Wind Turbines were first developed over 1300 years ago in Afghanistan. They were used by local residents to automate the task of pumping drinking water and irrigating crops, such as wheat and corn. Today Vertical Axis Wind Turbines are at the forefront of the micro wind industry. They are a practical, reliable, scalable and an economically viable source of renewable energy anywhere the wind blows.
Why is it called a Vertical Axis Wind Turbine? This is, for the simple reason that the rotator shaft of the turbine is placed vertically to the ground. This leads to a number of advantages that Vertical Axis Wind Turbines have over the Horizontal Axis Turbine.
Vertical Axis Wind Turbines are Omni directional meaning they do not have to adjust their orientation to match the direction of the wind. The benefit of this is that the energy generated from the wind is maximized regardless of the direction of the wind or the turbine. Additionally, being Omni directional means that Vertical Axis Wind Turbines use fewer parts and as a result, operating costs are substantially reduced and the durability and reliability of the product increases. These are significant advantages that Vertical Axis Wind Turbines have over their horizontal counterparts.
