Hi
Welcome to Fieldlines
I'm sure you can get something out of it, but it won't be a lot.
The case is open, which means that lots of water/dust/snow will get inside and rust it out.
The shaft is fairly thin - for a wind turbine to last you need big shafts and bearings.
Are you interested in re-winding the wire?
The electrical configuration now is another strike against it- single phase doesn't run smoothly as a 3-phase machine can, and it probably won't allow a lot of current to flow. Being a capacitor start + run motor that's a sure sign, in fact. Lastly, as a low-power motor, it will be a fairly low-power wind turbine. To make a rough estimate:
As a motor:
0.25 HP = 750/4 = 188 Watt
188 Watt / 220 V = 0.85 Ampere
As a generator, if you use a 12-volt battery:
14 Volt * 0.85 Ampere = 12 Watt
If you live in a windy place, this can maintain a bank of batteries with about 20 Amp-hours capacity. More if you don't demand much from the batteries, less if you use the battery power often.
There are rewards for having a higher-voltage system, and it will also benefit you to run the generator at higher voltage too. If it can - your motor may not offer wiring options to do this, without re-winding the wire.
