Vertical axis wind turbines (VAWT) for sale by online retailers

While recently having a discussion with my uncle about VAWTs has made an impression on me. I have reported on them here before, but I have not detailed all that much about them.

VAWTs actually require less wind than the traditional wind turbines do. They have a lower start-up wind speed required. Here are all of the online VAWTs for sale on the web, compliments of Google.
