Reinforced blade for a vertical axis wind turbine

A vertical axis wind turbine comprising:

• a blade comprising:
• a skin having a first skin section and a second skin section, wherein a first skin section thickness is greater than a second skin section thickness, and wherein the first skin section and the second skin section form a unified skin of the blade;
• a blade outside portion and a blade inside portion;
• a plurality of beam walls connected between the blade outside portion and the blade inside portion, wherein:
• at least one beam wall, from the plurality of beam walls, is located at a predefined distance from a leading edge of the blade, and
• the predefined distance is between 348 mm and 474 mm from a leading edge of the blade, corresponding to a range of 58% to 79% of a chord length of 600 mm of the blade, and wherein positioning of the at least one of the beam walls within said range is configured to optimize stress distribution, facilitate load transfer from the arms, and enhance structural integrity specific to a blade geometry and loading conditions of the vertical axis wind turbine;
• and
• a bracketed structural member disposed on the first skin section;
• a nut bar configured to be held by the bracketed structural member;
• and
• an arm configured to be attached to the blade via the nut bar.
