Gonna go out on a limb and say, I don’t have any issues with the power of modern ceiling fans.
The bigger, the quieter, the better. I’m surprised he didn’t instead comment on this trend of small, ultra fast ceiling fans that sound and look like a drone on the ceiling of the bedroom.













If nobody wanted them, including you, then you have your answer, no? Or maybe you are undecided? It sounds like you can’t decide if you want to keep them or not. Nobody here can make that decision for you.
Personally I don’t think an art project or a donation amounts to much more than avoiding the question of whether you want to keep them or not.
