This video shows a higher efficiency VAWT that is very easy to build. Drag type VAWTs are known to be very inefficient. By collapsing the drag element as it returns thru the wind, both the speed and efficiency are increased. Also very light materials are used and this makes it easier to support the unit. The generator can be located at ground level and this makes everything much easier.
Here is a link to more information about VAWTs.
