First off thanks for the quick replys on my first post. Now, I'm looking to build a home-made generator, I've been told that I can just reverse the motion of a electric motor and *poof* it becomes a generator, is this true? And I was also considering just using a automobile alternator as my generator, But at what RPM would the alternator have to spin to give off efficient charge to charge a 12v car battery?
