The polygonal windmill is essentially a windmill with the blade components contained within a rigid polygonal frame, preferably cubic in shape. The polygonal windmill relies on its much larger wind surface area rather than high speeds for energy production. The simple design of the frame and the blades allow the windmill to be constructed with off-the-shelf components and materials, i.e. minimal engineering and manufacturing costs, and minimal labor to construct the windmill. No special cutting or shaping of the blades is needed in the production of the polygonal windmill. |
