This is my smart drive wind turbine, its based round the smart drive alternators out of a smart drive washing machine. It is capable of producing a maximum of 1.6 kw's, most of the parts i found around my house and the blades are carved from wood. all the electronics i made myself so they are simple but effective. there is now a full step by step at http://www.instructables.com/id/Smart-Drive-Wind-Turbine-Tutorial/
This is perfect for off grid properties.
