| Abstract: Various technologies described herein pertain to a vertical axis wind
turbine blade configured to rotate about a rotation axis. The vertical
axis wind turbine blade includes at least an attachment segment, a rear
swept segment, and optionally, a forward swept segment. The attachment
segment is contiguous with the forward swept segment, and the forward
swept segment is contiguous with the rear swept segment. The attachment
segment includes a first portion of a centroid axis, the forward swept
segment includes a second portion of the centroid axis, and the rear
swept segment includes a third portion of the centroid axis. The second
portion of the centroid axis is angularly displaced ahead of the first
portion of the centroid axis and the third portion of the centroid axis
is angularly displaced behind the first portion of the centroid axis in
the direction of rotation about the rotation axis. |
