1. A fluid turbine comprising:
a rotor mechanically coupled with a generator; and
a duct in fluid communication with said rotor and surrounding said rotor; and
at least two sensors spaced about said duct, configured to measure static pressure; and
a processor to interpret signals from said at least two sensors; and
at least two flaps engaged with said duct and contiguous with a surface of said duct, mechanically coupled with motion activation equipment configured to rotate said at least two flaps contiguous with said duct surface and away from said duct surface; and
said motion activation equipment electronically coupled with said processor;
wherein
rotation of at least one of said at least two flaps alters a yaw direction of said fluid turbine to equalize measurement signals from said at least two sensors, and said signals may be interpreted to determine alignment of said fluid turbine with a fluid stream.
