Many current VAWT models resemble eggbeaters, with two blades attached to a central shaft, which is in turn anchored in a power generator. Others have a number of large, flat blades protruding from the central axis; and still others have a helix of extremely light plastic surrounding the axis. They typically stand between two and five feet in height and the best ones are able to attain 30 – 60% efficiency, depending on where they are located.sindhuhttps://www.blogger.com/profile/08541825289462669020noreply@blogger.com
