They should put a microphone in the top of the tower so that it will have the highest call to prayer in the world..

Excellent updates for an excellent tower project! There were talks that the Farmont will be opening there,according to the Saudi Forum. Excellent news if true.

That is a silly comparison as any engineer will tell you (and yes, I am an engineer). In the case of the wind mills, it is the 45m blades that are turning the the centre shaft. In the case of a clock, the centre shaft would have to turn the arm. BIG difference.
Yep. And the wind mill wings are balanced, the clock hands are not. Even bigger difference.
And then. That doesnt change the constraint, which is transfer of angular moment, which in the case of these windmillls is much bigger than for the clock.
