Abstract

Wind turbine farms are presented including: a number of steerable wind turbines each having a turbine diameter, where the number of steerable wind turbines is separated into a number of modules each placed in a fixed module placement and oriented in one of a number of fixed module orientations, where each one of the number of fixed module orientations corresponds with one of a number of prevailing wind directions, where the number of modules is separated into a number of sets placed in a number of fixed set positions. In some embodiments, each of the number of modules is positioned no closer than approximately six turbine diameters and no further than approximately fifteen turbine diameters from each another.
