The vertical axis wind turbine is an old technology,dating back to almost 4,000 years ago. Unlike the HAWT, the rotor of the VAWT rotates vertically around its axis instead of horizontally. Though it is not as efficient as a HAWT, it does offer benefits in low wind situations wherein HAWTs

Due to the vertical axis geometry of the rotor, the blade tips are close to the axis of rotation and travel a shorter distance per revolution. This results in a lower blade tip speed further reducing noise levels. Revolutionary blade tip designed to shed noise. Unique aero-elastic blades design captures turbulent wind and absorbs vibration.
