Abstract
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.
Claims17
A windmill comprising:
- a multisided frame formed of an open framework through which wind can pass freely having a first multisided section and a second multisided section with each section having at least one corner;
- said first section and said second section connected together by at least one connecting member at said at least one corner;
- two blades immediately adjacent to each other, each defining a plane such that the defined planes are angularly disposed to a horizontal axis such that said horizontal axis intersects said defined planes connected at opposite ends of the blade to the multisided frame and completely contained within said multisided frame, such that as wind strikes the blade, the windmill is rotated about said horizontal axis;
- at least one apparatus connected to the horizontal axis which is driven by the rotational force imparted by said windmill.

A windmill comprising:
- a multisided frame formed of an open framework through which wind can pass freely having a first multisided section and a second multisided where said first and second sections are rectangular in shape;
- said first section and said second section connected together by at least one connecting member at said at least one corner;
- at least two blades immediately adjacent to each other, each defining a plane such that the defined planes are angularly disposed to a horizontal axis such that said horizontal axis intersects said defined planes, connected at opposite ends of the blade to the multisided frame and completely contained within said multisided frame such that the blades are disposed in different directions such that of each of the blades, one end of the blade is connected to the first section of the frame and the opposite end is connected to the second section of the frame, such that as wind strikes the blade, the windmill is rotated about said horizontal axis;
- at least one apparatus connected to the horizontal axis which is driven by the rotational force imparted by said windmill.

A windmill comprising:
- a multisided frame formed of an open framework through which wind can pass freely having a first multisided section and a second multisided section where said first and second sections are rectangular in shape;
- said first section and said second section connected together by at least one connecting member,
- at least four blades [angularly disposed,] each defining a plane such that the defined planes are angularly disposed to a horizontal axis such that said horizontal axis intersects said defined planes, connected at opposite ends of the blade to the multisided frame and completely contained within said multisided frame such that the blades are disposed in difrferent directions such that of each of the blades, one end of the blade is connected to the first section of the frame and the opposite end is connected to the second section of the frame, such that as wind strikes the blade, the windmill is rotated about said horizontal axis;
- at least one apparatus connected to the horizontal axis which is driven by the rotational force imparted by said windmill.
