I wrote a blog about this the other day, and here is another story about vertical axis wind turbines.
However, don’t stop with the article. There are a number of comments that have valuable info in them. For example, the first talks about how wind power varies as functions of wind speed, the cross sectional area of the wind turbine, and altitude; in short, explains why wind farms use the giant propeller type turbine. The next one talks about aesthetics and the home owner, and why less efficient turbines are appropriate, or at least more applicable, in suburban and urban settings.
