You might want to do some research on just how much horsepower it takes to generate 120A. That's nearly 2KW of OUTPUT, not including the electrical losses in the alternator, the friction needed to operate the belts and pulleys, and so on.

Before the flameing starts, I realize fully that the thing isn't putting out 120A for long, but the point is, there is no free lunch. It DOES take real horsepower to operate
