windmills

recently i had the chance to watch closely 1 of those gigantic propeller blades for windmills (called wind turbines). i was on the road to toronto when we saw it towed by a trailer, and we reached it slowly. i could not believe my eyes how sophisticated it was. then, as we stopped at a road restaurant, the trailer stopped there too, so i could walk back and forth to my leisure. so many details.
and i think there are few chances to have 1 laying down so it could be studied completely. i was just lucky. turbulators, wind deflectors, devices to release static electricity, everything that any could imagine. i have been intrigued by the propeller and have studied it so it was the time of my life. but this is science fiction at hand.
