Nearly every one of the 80’ class and larger have carbon fiber leading edges and tips.
Static charge generation is a huge problem, along with ice buildup.
Yes, same thing with cell towers. One of the things I did in the wireless industry was design lightning protection systems for towers. Now I'm wondering how they would drain off charge from the blades? Draining the tower is easy, provided that soil conductivity cooperates. With the blades, though, somehow you have to be able to drain the charge from a rotating shaft that is part of a generator. Interesting.....
