Wind Generators

Gang: I couldn't stay away, and I'm sorry for scolding the net for so
much kit-talk. I realize now that kits are vital to the growth of QRP
and kit-building is the next best thing to homebrewing (or might even
be considered homebrewing) (had to cover myself there - recall the thread
6 months ago?).

Now, I'd like to get some ideas about making a wind generator to charge
batteries; during my weekend dumpster-diving at the harbor I periodically
find 120VAC fans (the interior of boats can get quite hot during the summer
months here in Hawaii many of the live-a-boarders keep a fan cranking
day and night while on shore power).

My question is this: can a 120VAC fan motor work as a generator? I know
the output voltage would have to be rectified and regulated, but will
there even BE an output voltage? Someone has said `yes, if the motor
contains permanent magnets'.

The fan I found this weekend has very nice 6 bladed prop - very sensitive
in that the slightest breeze will cause it to start churning, but I'm
not getting any voltage reading. I've tried to detect for permanent
magnets by running a thin steel blade into the housing but don't feel
any attraction so I doubt there are any magnets.

Anyone ever had success implimentating such an idea?

.73,
