You can rewind the alternator to output what ever voltage you want. So an alternator can be used but it can't be used to make a perpetual motion car. Its usefulness is limited to use when braking or going down hills. If it was on all the time, it would put more drag onto the car than what it would create. Hence the reason why they use them as electronic brakes.
