> So the "tallest and most dense wind farms are long past being completely invisible" means that they are so large as to be visible even from space? As you ascend, the tallest wind farms cease to become visible at about 30-40 miles of altitude. At that point you still have more 200 miles to ascend before reaching the low end of low earth orbit. So by the time you reach LEO, you are long past the point where wind farms became invisible. > This is begging the question. I am proposing you attempt to visualize the scale of things involved in your question, and that such a visualization ought to make the answer very clear. If the question were "at what point does my box fan collection affect the climate in my zip code" I would answer in a similar way.
