Thanks, that is an interesting idea. As concerned as manufacturers supposedly are about fuel efficiency, I wonder why they don't use higher efficiency alternators such as permanent magnet. There must be a reason, I just don't know what it is. Perhaps they wouldn't be reliable in such a harsh environment or something. I remember reading that there are ways to build alternators with 80-90% efficiency, but their downsides such as reduced output and reduced reliability in harsh conditions make them unsuitable for automotive use. I'm sure cost has something to do with it also, but there must be another reason.
