Ancient - as in 1000 years old and still working. These are in Nasjifan, Iran. The Ancient Windmills of Nashtifan NE Iran, a stones throw from Afagapcrapastan vertical windmills that produce - Flour Power! Along the southern edge of town, a towering 65-foot-tall earthen wall shelters residents from the abrasive gales. The high wall houses two dozen mostly functional vertical axis windmills that date back to ancient Persian times. It’s estimated the structures, made of clay, straw, and wood, are around 1,000 years old, used for milling grain into flour. These guy must have one hellva Preventative Maintenance program.... To compare to Western windmills of Holland, where they have been in use since the 11th Century. The oldest windmill probably originates from China and was built somewhere between the years 25 and 220. But this was a very different mill than the Dutch windmills. The Dutch windmills originate from the 11th century. The Netherlands used to have 10.000 windmills, nowadays over a 1.000 are still standing and most of them still work. Some of them are clustered together, this is called a ‘molengang’. For example, the 19 Kinderdijk windmills were built to work together is such a ‘molengang’. One mill alone can’t drain an entire area, but all the Kinderdijk windmills together were able to dry the land of the Alblasserwaar. Even back then and in the Europe, they had Govt supported wind power....some things never change... 300 your old windmills - still in use today Just a fun note, the 'blades' on these Dutch mills are actually sails, which can be set, reefed and struck - just like on a boat, albeit one that goes nowhere.... It's Friday and I'm Tired of the non-stop poly-ticks, so something fun to look at to give your noggin a vacation for a few minutes.

Just curious as to why the Scientific article I linked to was deemed not appropriate? It simply gave the history of a ancient tool that has a documented history of use of around 30,000 years and is even more widely used today than it was in its stone age forms. Looking again through the ROC or COC I find nothing that covers that link or its content. It was a very tastefully written article that gave the long history of said tool and its impacts on various cultures around the globe. The article itself did not go off into distasteful territory. So I am really not seeing the offense here.
Rope blocks fascinate me every time I use them. Think about them for a second and the guy or gal that created them. Amazing. It’s almost like magic.
