Patent ID: 8915697

Claim:
A method of moving a wind power extraction device comprising: providing a wind turbine having at least two rotating blades rotatable about an axis of rotation, each of the blades being configurable between a first open position substantially perpendicular to the axis of rotation and a second closed position substantially parallel to the axis of rotation, providing an articulated mast at a first end connecting to a support structure and a second end connected to the wind turbine, the wind power extraction device having: (a) a first storage configuration that positions the wind turbine at an elevation proximate to a platform, with the mast being substantially horizontal and the axis of rotation being substantially parallel to and laterally offset from a long axis of the mast; and (b) a second deployed configuration that positions the wind turbine at an elevation remote from the platform, with the mast being substantially vertical and the axis of rotation being substantially perpendicular to the mast; first moving the wind power extraction device from the first storage configuration to the second deployed configuration; and second moving the wind power extraction device, after the first moving, from the second deployed configuration to the first storage configuration; maintaining, during the first moving and/or the second moving, the axis of rotation of the wind turbine in an orientation that is generally horizontal as the wind power extraction device moves between the second deployed configuration and the first storage configuration.
