NOT perpetual motion, altenator regen?

Alright now bear with me guys, it accured to me that since I'm utilizing the 9" ADC double shaft motor,and I'm not using the double shaft end for any purpose, why not use pullys and belts to drive an altenator ( free wheeling most of the time), coupled with switches so that when I hit the brakes it turns on the altenator, slows down the vehicle and acts as a form of regeneration. I've already been told that my series DC motor isn't suitable or designed for regen and I'm mostly interested in the range of my vehicle. I can imagine that even in the freewheeling state said altenator would decrease my range just by turning the shaft, but what of the regen. possibilities could they significantly increase my range? I do live in a little bit of a hilly regon as a matter of fact if i go one way from my house I immeadiatly asscend a 300-400ft hill, I would love to be able to recapture some of that expended energy on the other side of the hill with regen......... comments?

Hopefully this didn't post twice.
It is possible to obtain higher voltages from an automotive alternator. Try to find one that uses an external regulator. I got 80 volts from a late 80's- early 90's unregulated Chrysler alternator coupled to a 3000 rpm ac motor with 12 volts applied to the field coil of the alternator. I set this up on my workbench and connected the alternator's output to 5 discharged 12 volt batteries. This caused considerable drag on the alternator and ac motor. So some braking should occur. Don't yet know what running this for an extended period of time would do to the rectifying diodes.
