Cool. I've never seen one in a crate before.

Very cunning. The largest ones have a rotor diameter of 220m so 721 feet, give or take. That makes each blade at least 355 feet long!
We don't have anything that size here. But the ones we do have still require amazingly large concrete footings. Each footing for the ones we have here is 375 cubic metres of 30MPa concrete and 28 tonnes of reinforcing steel. Now, take into account that each concrete truck transports 6 cubic metres of readymix and you'll see that, for each footing, that means 63 concrete truck loads! At four trucks an hour, you're still looking at a 16 hour continuous pour.
