The windmills of Nashtifan, Iran, some of which have been in operation for nearly 1,000 years. These windmills use a vertical-axis design that has been in use since the time of the ancient Persian empire; the strong winds of the area are funneled toward the turbines by the walls around them. {WHF} {HTE} -- source link
