Wind power. A Darreius turbine or Vertical Axis Wind Turbine (VAWT),near Albuquerque in New Mexico,USA. The two catenary-shaped aluminium blades are fixed along a rotating column giving the structure its distinctive 'eggbeater' appearance. Despite the fact that this turbine is not self-starting even in high winds,it does have a number of advantages over the conventional horizontal axis aerogenerator; the axial symmetry of its design obviates the need for re-alignment in response to shifting wind direction and their is no need for the generator itself to be mounted at the top of the tower | |
