Vertical Axis
Wind Turbines
A new way to harness wind power.
What are vertical axis wind turbines?
Vertical axis wind turbines are a type of wind turbine where the rotor blades rotate around a vertical shaft. Unlike the common fan-like design seen on horizontal-axis wind turbines, the blades of vertical axis wind turbines often appear in the spiral shape or H-shape.
Pioneering based on ancient wisdom
Although horizontal axis wind turbines are the most well-known wind power generators, vertical axis wind turbines are the oldest among wind turbines. Simple yet robust, the use of vertical axis wind turbines dates back to as early as the 7th century as a Persian invention.
Turning motion into electricity
Wind turbines produce electricity from kinetic energy in the wind. By rotating the rotors, they generate electrical current. When connected directly to the power grid or integrated with power storing units, they become autonomous power providers limited only by wind.
The two working principles
Savonius: The Resistance Runner
Savonius vertical axis wind turbines use the flow resistance principle of the rotors. The dynamic pressure of the wind against the blades creates a drag effect, pushing the blades into rotation. Because of this, Savonius rotors never move faster than the wind speed.
Darrieus: The Uplift Runner
Also known as the “egg beater”, Darrieus vertical axis turbines use the lift effect of the blades. By flowing around the structure, the wind creates a suction on the front side of the turbine, driving the blades to rotate. The rotation speed of a Darrieus turbine can be significantly faster than the wind speed.
Why choose vertical axis wind turbines?
Although vertical axis wind turbines has lower power output capacities compared to horizontal axis wind turbines, they have qualities that make them the best solution for populated areas and small-scale usage on various landscapes.
