Have you heard of vertical wind turbines used on an industrial scale?

I just saw a program on the BBC about wind farms in New Zealand. The main complaint was noise and subsonic vibrations. Why all the big companies chose the classic 3 turbines of blade / / / I had heard "somewhere" that vertical W / T are much quieter and more efficient are … They are viable on a large scale? It was interesting …. Thanks for any information

Yes they are sold commercially. They are being considered by the Princess cruise lines to provide some power, while the vessel is port.They also docked in the spec-ed by security companies to provide power for pole lights to feed parking and wireless security cameras from the top the poles. And yes they are very quiet.

Do Wind Turbines Make Noise?

Wind Turbine Noise $94.50 Noise from wind turbines is a major constraining factor in the location of turbines. A recent survey in the Netherlands showed that sound was the aspect of wind turbines which led to most complaints. Investigation, understanding and reduction of noise from wind turbines is a necessary progression in the development of this sector of renewable energy. This book, authored by an international grou…
