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?

If you look at ebay for a PMA (permanent magnet alternator) coil you will see several stator coils listed and they are not too expensive. Of course for this application you would not use a permanent magnet rotor as you want to be able to turn it off. The point is that some of these coils can put out well over 300 volts and a stock rotor can handle well over 12 v for short periods of time. The one thing to watch is the diodes, use the style alternator that uses the press fit ones on the plate inside the back as these can be easily replaced with 600 volt ones. I think that would be a 10si or 12si early model GM alternator.
