I saw one time in a 4wd magazine where it was suggested that in the backcountry you carry a chainsaw with no bar or chain but with an appropriate sized v belt and pully so you could hook it to your truck's alternator in case of a dead battery...
That's the stupidest thing I've ever heard. Take a _usable_ chainsaw with you, having figured out how to flange a belt to it in the field. You're more likely to need the saw than the charger!
