If I'd been present when the one of the local ones caught fire, _that_ would have been interesting. Lightning strikes are also supposed to be good - for pictures.

Re: PESO: Wind Turbines--Response
Thanks for the comments. Yes, these are hard to shoot, and I deliberately chose a dark day to eliminate the problem of white turbine blades against a bright sky. I hoped that the tracks through the field in the foreground would lead the eye into the photo. The problems are that these things are widely scattered, and rather static at the shutter speed necessary on a blustery morning (too windy for anything less than a 10kg tripod; maybe the K10D would have managed at 1/20 or so had it been available!). Re wind power: I found these devices very intriguing, and did a good deal of reading about them. The main problem is that the wind blows least when the power is needed most (a hot, humid summer day), and blows the most when power is needed least (a wet 4C November morning). So, power companies have to keep lots of capital tied up in fossil-fuel-burning reserve capacity, and that's not attractive.

Re: PESO: Wind Turbines
You can see them all over the American west as well. They're somewhat of a solution to energy problems, but not very efficient. Interestingly enough, a lot of east-coast democrat congressmen and women were high on these at one time. And then someone proposed building some within viewing distance of the Kennedy compound on Martha's Vineyard. Now wind-powered generators are suddenly taboo among the liberal leadership. Go figure.
