ABSTRACT:
BACKGROUND OF THE INVENTION
The world is dependent on natural resources for the production of energy. This dependence is resulting in a depletion of the natural resources available in the world. Also, the pollution produced as a result of using natural resources has become a problem that will last for generations to come.
Industry is concerned with the increase in prices for natural resources since these costs directly impact the competitive pricing of their products. Consumers are concerned with the price they must pay for electricity. Analysts are concerned with the diminishing supply of natural resources. Environmentalists are concerned with the pollution caused by using natural resources in the production of energy and the consequences of an accident at a nuclear power plant.
Wind is a renewable energy source that can be used to produce energy rather than non-renewable sources such as coal or oil. Wind energy can replace nuclear power plants if the technology and cost savings were found.
SUMMARY OF THE INVENTION
Traditionally, windmills have required extensive cutting and shaping of the blades, resulting in high engineering and manufacturing costs. Also, traditional windmills rely on either/or high wind speeds or high altitude posts.
The polygonal windmill relies on its much larger wind surface area rather than high speeds for energy production. But the faster the wind, the greater the amount energy produced by the polygonal windmill. A high altitude post would enhance the performance of the polygonal windmill but is not needed for its operation.
The polygonal windmill is physically and structurally stronger than traditional windmills. It can withstand wind speeds that would normally destroy traditional windmills.
The polygonal windmill is essentially a windmill with the blade components contained within a rigid polygonal frame, preferably cubic in shape. 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.
