These impressive towers, just a shade under 300 feet (I'm of an age that doesn't do metric), are the first outward sign that production has really gotten off the ground at the new Siemens wind power plant in east Hull. The blades that go with these babies are nearly 250 feet long. When it comes to wind power it seems size matters. These are destined to sit in the North Sea and power our homes and industry at least while the wind blows. I suppose we'll get used to seeing these things over the coming years but they were quite a surprise when first seen the other day.
