Abstract
A wind turbine operable as either a vertical axis wind turbine or a horizontal axis wind turbine is disclosed.
Claims26
A wind turbine vane including:
- a) a first end;
- b) a second end spaced apart from said first end;
- and
- c) a leading edge connecting said first end and said second end and substantially conformed to a surface of a spheroid having a polar axis, said leading edge approximating a sine wave having a neutral axis substantially parallel to a longitudinal axis of said vane, said longitudinal axis approximately bisecting a chord of said first end and a chord of said second end and skewed relative to said polar axis such that a projection of said longitudinal axis beyond said first end does not intersect said polar axis.

A wind turbine comprising:
- a) a vane support arranged for rotation about an axis of rotation;
- and
- b) a vane attached to said vane support, said vane including:
- i) a first end;
- ii) a second end spaced apart from said first end;
- and
- iii) a leading edge connecting said first end and said second end and substantially conformed to a surface of a spheroid having a polar axis, said leading edge approximating a sine wave having a neutral axis substantially parallel to a longitudinal axis of said vane, said longitudinal axis approximately bisecting a chord of said first end and a chord of said second end and skewed relative to said polar axis such that a projection of said longitudinal axis beyond said first end does not intersect said polar axis.

A wind powered energy converter comprising:
- a) a foundation;
- b) a substantially vertical tower having a first end supported by said foundation and a second end;
- c) a wind turbine rotationally mounted on said tower proximate said second end;
- d) a power transmission apparatus having a first connection to said wind turbine and a second connection;
- e) a flywheel rotatable by said second connection of said power transmission apparatus, a mass of said flywheel variable by altering a quantity of matter comprising said flywheel;
- and
- f) an energy converter attached to said flywheel to convert the rotational energy of said flywheel to another form of energy.
