Green machines

I was at work in November in the Science Gallery during an exhibit on environmentally friendly contraptions, and a little girl in a splendid red raincoat came up to me. Pointing at our model of a newly designed rooftop wind turbine, she asked rather incredulously: "Excuse me, what is the purpose of the giant blender?"

It did indeed look like some sort of whisk. I was delighted with her curiosity and perceptiveness, and wished more of my customers asked such things.
