Dutch startup TouchWind has created the Mono, a tilting, one-bladed turbine that claims to survive extreme wind speeds and reduce energy costs by up to 30%.
Touchwind''s single-blade design solves both these issues in one stroke. How does a single-blade turbine work? The blade is attached to the mast at a slight upward angle. When the wind...
An unprecedented floating offshore wind turbine design, Touchwind''s wind turbine has only a single blade and does not require complex active pitch control, which can reduce costs and
Below rated wind speed, the generator torque control is active while the blade pitch is typically held at the constant angle that captures the most power, fairly flat to the wind.
The design of Touchwind is different from the traditional three-blade giant wind turbine that looks like an electric fan. This technology has only one long leaf, which looks like a hang glider,
How Do Wind Turbines Work? Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like
As you approach an individual wind turbine, its enormity becomes apparent. You realize that the blades and tower must bear the force of the wind pushing them backwards, and they must be very strong to
Touchwind claims its innovative single-blade turbines will solve several problems to drive down cost and downtime, using a single, huge blade with no fancy active pitch controls.
How does the single-wing floating wind turbine work? The machine, named after Mono, has a huge single-piece rotor, installed perpendicularly to a pole that is connected to a large floating barrel.

The ratio between the blade speed and the wind speed is called tip-speed ratio. High efficiency 3-blade-turbines have tip speed/wind speed ratios of 6 to 7. Wind turbines spin at varying speeds (a consequence of their generator design). Use of aluminum and composite materials has contributed to low rotational inertia, which means that newer wind turbines can accelerate quickly if the winds pick up, keeping the tip speed ratio
One of the latest innovations being developed and tested at the Harry Butler Institute by Dr Jonathan Whale is a wind turbine with a single vertical blade. This contrasts with the three bladed
