Mariah Windspire

Mariah and its Windspire will go down in history as another novelty Vertical Axis Wind Turbine that was doomed from the start. Tall and slender, it was, if nothing else, distinctive. Unfortunately, a tall and slender wind turbine mounted on a short tower is still a wind turbine on a short tower. The company soon realized that the design was really only suitable in "architectural" applications that were looking for visual bling. Architectural ornamentation alone is not enough of a market to support a wind turbine manufacturer as Mariah learned to its regret.

If you don't know why these are bad installations, then please read a good book on wind power. There are dozens of such books now available in English.
