Sprouting Windmills

We've had just the right amount of rain this year for growing beans and corn. The windmills are growing pretty well too. I finally got a chance to check out the progress for myself the other day and sure enough, the first five turbines are in the air! Here's a view of one and one under construction from about a mile away, looking out over the bean fields. The picture is a bit washed out and grey because it was, well, rainy.

The car, the crane, and a partially assembled tower. The crane is the same one that I raved about a month or so ago.
For scale, I had Kenrick stand next to the nacelle, or generator housing. The cylinder in the foreground is the top section of the tower. It has the ladder and power cables already installed inside. Cool, huh?
I don't know for sure, but I think these are 1.5 MW (Mega-Watt) turbines from GE. According to the specs, it has a 60 to 100 meter (197 to 328 ft) tower and a 77 meter (252 ft) diameter rotor. That's big, but not as big as their new 3.6 MW turbine, which has a 104 meter (341 ft) rotor diameter! If you laid those rotors flat on the ground, their swept area would cover just over 2 acres! Enough exclamations! Okay, I'm done already! Bye.
