Abstract
A vertical axis turbine includes a rotatable hub assembly that is configured to be connected to an energy sink and rotatable about an axis of rotation. At least two blades are mounted on the hub assembly, each blade including a leading edge and a trailing edge, the blades being oriented so that the respective leading edges face in a common rotational direction. Each blade further includes a straight section that is substantially parallel to the axis of rotation and two helical sections, the straight section being interposed between the helical sections, and the helical sections extending at least partially around the axis of rotation.

A vertical axis turbine that includes:
- a rotatable hub assembly that is configured to be connected to an energy sink and rotatable about an axis of rotation;
- and
- at least two blades that are mounted on the hub assembly, each blade including a leading edge and a trailing edge, the blades being oriented so that the respective leading edges face in a common rotational direction, and each blade further including:
- a straight section that is substantially parallel to the axis of rotation;
- and
- two helical sections, the straight section being interposed between the helical sections, the helical sections extending at least partially around the axis of rotation, and the helical sections being substantially identical to each other.
