Is there a way I can power small appliances with the motor? I really am just interested in powering Lights(5 fluorescent) or a single fridge.
 I also have a spare car battery that I would like to link with the 12volt, any help on connecting those two together would be nice as
All you have to do to power a 110V appliance from a 12-volt battery is purchase an inverter. Connect the inputs to the battery and you have 110VAC
outlets on the inverter itself. No motor is required. I got the inverter I used in my truck for years at WalMart; 700W continuous duty, was enough for
a laptop and TV, plus I could manage to run a small battery charger if I needed to (like for flashlight batteries), and it cost about $80.
You won't be able to continually use any such power system indefinitely without recharging, however. Your initial apparatus with the motor simply had
enough charge to run that long; it did indeed use some charge, although not enough to drop the voltage yet. Batteries do not slowly lose voltage as
they discharge; they barely lose any until the charge is almost depleted, then drop off quickly as it id fully depleted.

When looking at wind power, why cant one use a 230w heavy duity car alternator from a junk yard instead of a purchased unit from some
You can, definitely. But you have to have enough power and speed to use it (as you mentioned).
230W is approximately 3 hp that you will need to get out of the fan blades. You'll also have to have the alternator turning at a minimum of 1000 RPM
to get good output power from it. Unless you have a gale-force wind, that's some big blades, and that's a lot of gearing (although pulleys would be
cheaper and easier) in any case.
