风车在人类在地球上繁荣的能力突出显示。风车从使用风力磨削（磨机）谷物的谷物获取食物。可持续食品生产的主要积木之一是面粉。如果您没有尝试过，手动磨削面粉需要很多工作。与许多人的努力一样涉及工作，找到更容易获得工作的努力成为优先事项。
One of the earliest known forms of for a working windmill is the vertical wind mill for grinding wheat found in Nashtifan, Iran. According to historians, the first writing and sketches of this style of windmill occurs between 700 and 900AD, although this form of windmill may have already been in use for quite some time. The windmills in the photo are known to have been in existence for at least 2-300 years according to the local caretaker and are working to this day.

For those readers with a business background, consider what the amortized cost of these windmills might be based on an operating life of 2-300 years and negligible maintenance expense. They are virtually free.
The ancient Persians located the windmills in arrays on rises where they could take advantage of seasonally high winds and increase the effectiveness of the winds by ducting arrays of wind turbines located right next to each other. These windmills operate 120 days out of the year when the spring winds blow in Iran, 33% of the time, slightly higher than the horizontal windmill of the modern era.
在解决任何机械问题系统时，重要的是要仔细考虑所需的任务并找到最简单，最具成本效益的解决方案。波斯风车简单，廉价，并在所有风速下运行。它有效吗？不是特别的。有人关心吗？当然不是。这是工作，并没有成本没有操作。
From a mechanical standpoint notice that the vertical windmill requires no tower, has no gearbox, no steering, no brake to limit the rotor from turning too fast, and doesn’t kill birds. The vertical windmill is ducted slightly to improve the density and speed of the wind in the area of the rotor. This simplicity of construction and siting can be applied to the mechanical problem of creating electricity from wind.
Wright Brothers在Kitty Hawk北卡罗来纳州的动力飞行中开始努力，因为它是恒定的陆上风。美国沿海地区提供了潜力，使正确解决方案可能产生50或75％的设备，而不是25％的DOE报告水平风。
If a system were simple, inexpensive and extremely lightweight, it could be placed on coastal high rise buildings without any need for expensive towers. There are a number of companies attempting to approach wind power in this manner. Hopefully a technology winner will differentiate itself from the mainstream in the coming years.
