You may have seen this photo online recently of EDF's floating offshore vertical-axis wind turbine (VAWT) called "Vertiwind." It has a nameplate capacity of two megawatts. The Vertiwind will be part of EDF-EN's offshore wind farm project called Inflow, which the European Commission is helping fund. The strange design piqued my curiosity about VAWTs. Why…

Vertical-axis wind turbines were the first structures developed to produce the electricity, paradoxically in contradiction with the traditional windmill with horizontal axis. They have the advantage of having the control members and the generator at the ground level, which make them so easily accessible.

With vertical axis windmills (on the Darrieus models, or some of the Savonius designs which has open space between the blades and the base) -- the blades are located at a distance away from the base of the shaft. The centrifugal force that happens with the bulk of the blade weight at a distance from the shaft causes structural wear over time.

A vertical-axis wind turbine using sails rather than solid blades has been designed and tested at large model scale in a 15 ft diameter wind tunnel. The turbine has a relatively high solidity, three blades and an operating range of tip speed ratios from zero to about 2.5. Two types of sail have been tested—a double sail consisting of two ...

Horizontal axis turbines are often easier and more efficient to scale (by extending a tall, vertical tower) than their vertical counterparts. Horizontal axis turbines also experience little variable interference of the wind flow between blades, whereas with a vertical axis turbine there is direct and unavoidable interference.

turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and wide use. Figure 1.2 shows a diagram of these two types of systems.
