Having a fairly long commute each day, I have time to think through some different ideas to improve my mpgs. I know that an alternator delete can make for a pretty substantial improvement, but I am pretty nervous about doing it. A 45 mile commute, each way, is a long distance. Even if I bought a deep cycle battery, I'd be worried about getting stranded.

That said, I saw people talking about a DC-DC converter here a couple of weeks ago. Cool, now I can string a couple of batteries together in series, mounted in the trunk, run a DC-DC converter outputting ~14.5V and delete the alternator. But it seems a shame to have a battery pack and only to delete the alternator.

But here's where my cogitating went: What if I added a couple more batteries and used it to power a small motor mounted in the current location of the alternator? Could I disconnect the motor's drive pulley and use the motor to drive the accessories?

Okay, what's wrong with this idea? Surely I'm missing something.
