This is a bit of a silly thread, but I'm curious if that's the case. Assuming that the issue is that the blades are hard for birds to see, not "impossible", then having them black on the windward side may solve the problem. For a given wind speed `x` and bird flight speed `y`, the relative speed when approaching the blades from the windward side would be `x + y`. The relative speed when approaching from the leeward side would be `x - y`, giving the bird additional time to react. ... on the other hand, at `x + y` the bird's body would pass through the blade plane is less time than at `x - y`, potentially reducing the likelihood of a strike. Now I'm curious if there are data showing where birds have been found dead are wind turbines. Intuitively, I would expect there to be more dead birds on one side than the other.
