Configurable multi-purpose cross-flow wind turbine with performance enhancements

A turbine comprising:

• a plurality of primary blades disposed at regular intervals around an axle;
• a plurality of secondary blades disposed around the axle between the primary blades of the plurality of primary blades, each secondary blade of the plurality of secondary blades being smaller than each primary blade of the plurality of primary blades, each secondary blade of the plurality of secondary blades being positioned such that each secondary blade provides a shielding effect to an adjacent following primary blade of the plurality of primary blades;
• and
• a plurality of tertiary blades disposed between the plurality of primary blades and the plurality of secondary blades, each tertiary blade of the plurality of tertiary blades smaller than each of the secondary blades of the plurality of secondary blades, wherein at least the primary blades and the secondary blades alternate contributions to torque transmitted to the axle through redirection.

A turbine system for generating electricity, the turbine system comprising:

• an electric generator;
• and
• a turbine comprising:
• an axle mechanically coupled to the generator;
• a plurality of primary blades disposed at regular intervals around the axle, the plurality of primary blades;
• a plurality of secondary blades disposed around the axle between primary blades of the plurality of primary blades, each secondary blade of the plurality of secondary blades being smaller than each primary blade of the plurality of primary blades, each secondary blade of the plurality of secondary blades being positioned such that each secondary blade provides a shielding effect to an adjacent following primary blade of the plurality of primary blades opposite a direction of a rotation of the wind turbine rotor;
• and
• a plurality of tertiary blades disposed between the plurality of primary blades and the plurality of secondary blades, each tertiary blade of the plurality of tertiary blades smaller than each of the secondary blades of the plurality of secondary blades, wherein the primary blades and the secondary blades alternate contributions to torque transmitted to the axle through redirection.
