10 Wind Turbines That Push the Limits of Design

Dec 18, 2009 · How It Works /// Traditional wind turbines capture horizontal winds and must rotate to follow changes in wind direction. The qr5's helical design allows the turbine to collect wind from all directions equally. Where To Find It /// The first qr5 turbine was installed in Dagenham, a suburb of London, in March 2007.

This turbine produces around 5,000kWh/year with an average annual wind speed of 4m/s or around 15,000kWh/year at 6m/s. Taller towers and good siting allow wind systems to access faster wind speeds. Manufacturers should state the 'cut-in' wind speed of the turbine, the speed at which the wind generator begins to turn and generate power.

Vertical axis wind turbine - Wikipedia

A vertical-axis wind turbines (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair.

However, wind turbines do not occupy all of this land; they must be spaced approximately 5 to 10 rotor diameters apart (a rotor diameter is the diameter of the wind turbine blades). Thus, the turbines themselves and the surrounding infrastructure (including roads and transmission lines) occupy a small portion of the total area of a wind facility.
