How do you know from what direction the wind is coming? And don't windmills in Ireland spin the opposite direction than the windmills in Holland. This has me so curious that I am going to have to google windmill directions all day long.
It looks find to me and more fine each time I watch the video, though I am not sure why and it's now driving me mad. I must know the truth of the matter.
I know the way the wind is coming because the trailing edge is the one that is leading. If it is merely the angle of the blades that is causing it then whoever built the windmill didnt know what they were doing. I assume that even in this fantasy world that those who took the time to build such a machine would take the time to do it correctly.
Most windmills can be rotated so that the wind hits the blades from the front.That way, the leading edge will always cut in to the wind. If they can't, they certainly wouldnt be built in the manner that the one in the trailer is built. There are various designs that function best under particular conditions.
Also, it's a lie that all windmills in Ireland spin the opposite direction from ones in Holland. Like I said, there are various designs that dictate the rotation of the blades. You will find counterclockwise and clockwise spinning windmills all over the world. What you will never find is one where the trailing edge cuts in to the wind...that is to say, that the trailing edge is the one that is leading. (unless the design is like one I pointed out in my previous post, where the trailing and leading edge are the same width. In that case the direction of the wind and angle of the blades are what determine the spin)
