    The Eiffel Tower is 330m tall at the tip. This windmill is 185m at the hub, and with the blades being 153m, that adds up to 338m. Technically taller than the Eiffel Tower.

    However, the blades are spinning, which means the windmill has a variable height. With three identical, equally-spaced blades, the windmill would vary in height between 338m at the tallest, and 261.5m at the shortest. The average height of the windmill, assuming the blades keep moving, is just shy of 300m. In fact, the windmill is only taller than the Eiffel Tower about 10% of the time. Even if we include the changing height of the Eiffel Tower, which has ranged from its current 330m to as low as 312m, or even if we take the Eiffel Tower’s architectural height of 300m, the Eiffel Tower is still, on average, taller than this windmill. I will grant that the maximum height of the windmill is higher than the Eiffel Tower, but both the median and mean height of the Eiffel Tower is greater than both the median and mean height of the windmill.

    Not knocking China or their engineers for this tremendous achievement, I just think they would want to play this kind of thing straight.
