Wind Farm field trip

Yesterday we drove up into the hills, got lost twice and finally ended up on an unlabeled dirt road to see the windmills! Now, these things are HUGE and you can see them from most anywhere so you would think it would be tough to get lost but there are 19 of them and, well, they all look exactly alike. We did finally find the windmill that our homeschool group was visiting, though, and it was a spectacular sight.

These stand over 300 feet tall. The rectangular part at the top that houses the generator is as big as a school bus. And each blade weighs seven tons! As I stood under it to take this picture, the clouds were moving in such a way that it looked like the turbine was moving toward us (or falling on us) - kind of scary. Especially given that one DID fall last year - I am not making this up. Fortunately, the injury list was limited to several rows of corn.

There was an actual blade that the kids could explore. These are hollow on the actual windmills and workers can walk inside them when necessary. 300 feet up and in complete darkness. Now there's a job my high school guidance counselor never mentioned. Go figure.

The blades are made of fiberglass.

And make a lovely play structure if you have the room.

We found out that these 19 windmills produce enough power to run 9,500 homes. Amazing!

Interesting note:
Since the hills upon which these windmills stand lie directly under a major migratory flyway, there was apparently some concern that birds might be killed by the blades. Several environmental agencies came out and checked around and, finding no dead birds, they came back with some of their own and spread them around the bases of the windmills!

No, really, I promise I am not making this up.

The idea was that maybe birds really were being killed, but they were quickly being dragged into the woods and consumed by predators. After a week of checking on the carcasses, they were satisfied that this was not the case. One could go into a discussion of the ethics involved in killing one set of birds to see if another set might be in danger but one won't because one needs to go to bed.

I did mention to Z-Man that, again, through obvious negligence, I was never made aware of "dead bird distributor" as a potential career path. And I guess I'm OK with that.

  1. Cool field trip!! We see the semis driving through town with these blades frequently, but I don't know where they are taking them, since I don't think we have a wind farm around here.
