Is it possible to use a step up transformer to increase the voltage delivered by an alternator? If so how much can you increase the voltage just depends on how many turns the copper has or what?

If your refer to AC then sure. What is the context of your question?

Yes I was referring to AC. I was meaning it in the context of using an alternator to charge multiple batteries say hooked up to a stationary bike or something.

That's perfectly possible. Its actually what's done all over the world. But remember, the Higher the voltage you use, although the conductor size decreases, you will be paying higher due to added cost of insulators.

There's usually some optimum operating voltage, based on copper prices and safety. 110 or 230V are good choices for domestic supplies but lower volts afe good for charging batteries as the current won't be all that high.
There's a lot to be said for using 12V because that's a common voltage for batteries and you can usually charge a number of batteries in parallel (you may consider blocking diodes to prevent batteries discharging into one another).

Its possible to use step up transformer to increase the voltage delivered by an alternator. You only decide the limit for your step up voltage. Just search in the market about what rating of transformer is available and what is your output voltage requirement.
