Jeff Berezin of Berezin Technologies shows us how to make a vertical axis, Savonius wind turbine using plastic barrels.
“The Zoetrope is a vertical-axis wind turbine made from common materials such as stove pipe, metal brackets, plastic sheet and a trailer hub. Many of the materials can be found at local hardware or home improvement stores, the rest can either be made at home or purchased online. The Zoetrope was commissioned by Washington (USA) resident and renewable energy supporter Mike Marohn to provide supplemental water heating.
Applied Sciences made the decision to open source the wind turbine and provide a freely available introduction to wind power, thereby allowing others to improve the design and functionality.”

Since it is a vertical axis wind turbine, the Zoetrope avoids many of the problems of the horizontal axis wind turbines we are more used to seeing such as noise, creating hazards for birds and so on.
