Vertical Axis Wind Turbine Evaluation and Design

These turbines spin on a vertical axis. Figure 2.6 is an example of a Darrieus vertical axis wind turbine. This turbine is an example of a commercially used vertical axis turbine. One of the major problems with vertical axis wind turbines is that an initial force is required to start the turbine's spinning.
