What is a Wind turbines?
This is a placeholder for an exploded diagram of a Wind turbines
Basic Information
A wind turbine is a device that converts kinetic energy from the wind into electrical power. The term appears to have migrated from parallel hydroelectric technology (rotary propeller). The technical description for this type of machine is an aerofoil-powered generator.

The Golisano Institute for Sustainability
The vertical axis wind turbines in use at GIS are darrieus helicoidal type turbines. This means that they have airfoil shaped blades twisted around a vertical axis of rotation.As the wind blows over the cross-section of the blade, it creates a pocket of low pressure underneath resulting in a pulling force on each blade that causes them to move toward the low pressure. When this happens at a high enough speed, the force to move the blades finally surpasses the magnetic forces in the generator and the turbine starts to spin. As the low speed shaft of the turbine spins, it spins the input shaft of a gearbox that outputs a much higher rotational speed to turn the generator to produce electricity. This electricity is fed into the GIS buildings micro-grid, which in turn distributes the energy around the building when it is demanded from a battery storage system.
