I have a annemometer cups that I want to see if the miniscule power output will trickle charge a cell phone battery. I'll try it while I'm home and post the results.
I read a post about this either here or read an article about it somewhere elese. The general idea was the annemometer had some "electrical" things that didn't work out so well. I'll look for it. I know that is in no way helpful but I just I would put my 1 cent.
