A trillium wind turbine can have a plurality of blades. Together, the swept-back, complexly-curved blades can be attached to an electricity-generating nacelle. Each blade has a main blade, and a trailing edge blade, and can optionally have a diversion blade. Wind is directed down the length of the blade and exits the tip. The main blade resembles a portion of a cylinder in form, the cylinder being twisted to change the angle of attack, thereby adding more lift throughout the length of the blade. The trailing edge and diversion blades are pitched relative to the wind and produce lift. Additionally, wind hitting the diversion blade is diverted behind the blade. Because the surface area and volume of the blade are larger near the base and smaller at the tip, the air traveling along the blade increases in velocity producing more thrust/lift. The turbine also automatically faces into the wind without the need for sensors or positioning motors. |

1. A trillium wind turbine blade, comprising:
a main blade extending along a main blade longitudinal axis from a proximal end to a distal end and having a blade tip at the distal end; an edge extension protruding out from a top edge of the main blade and attached thereto and wherein the edge extension begins in proximity to the proximal end and extends down the main blade towards the distal end, the edge extension first increasing in height from the main blade and then decreasing in height; a trailing edge blade protruding out from a bottom edge of the main blade and attached thereto and wherein the trailing edge blade begins in proximity to the proximal end and extends down the main blade towards the distal end, the trailing edge blade first increasing in height from the main blade and then decreasing in height; and a combination comprising the main blade, the edge extension, and the trailing edge blade, the combination being cupped inwards so as to have a volume and an inner surface area, the combination catching and directing a wind down a length of the blade. |
