WIND TECHNOLOGY HISTORY-BRIEF

Wind-driven mills are of ancient origin. Simple windmills may have been used in Persia (now Iran) as early as the 7th century AD. They were used for irrigation and milling grain. The wheel bearing the wind sails of the earliest windmills was horizontal and supported by a vertical shaft. These machines were relatively inefficient. Nevertheless, this type of windmill spread to China and throughout the Middle East.
