Windmills

Have you ever wondered just how big those windmills are that you see off in the distance? Last week, I had the chance to get out and see some of them up close. I knew they were big but they are huge. It's impressive when you calculate the velocity of the blade tips. I think they are doing about 0.5 revolutions per second.

Here are some blades lying on their side.
The tower is two pieces stacked one on top of the other. This picture does not even show an entire piece.
You can see hundreds, if not thousands, of these windmill dotting the West Texas landscape. Just five years ago there was not one. I guess it is Texans doing their part to save the planet.
