Windmill direction based on illustration.

[Mdanner423]

How can you tell which way a windmill will blow based upon an illustration of it's blades? I've done some research and can't understand it!

The wind is blowing directly at it. There are different shapes of the blades but I haven't been able to determine how that shape determines direction. The wider part of the blade is on the left side, with a skinnier side on the right.

Thanks,
Matthew

You need to post some illustrations or pictures or something. For some windmills it is obvious which way they will turn (the propeller type), but for some it is much less obvious.
