I'm actually looking at building a tubular setup with multiple coils and magnets its length that is capable of producing 14.4 or better, which will then be rectified and converted to DC, used in a situation similar to an automotive electrical system, to charge batteries that are in use. I don't know if there is a single iteration that could replace an existing charging system, but there is most certainly room to use such a device concurrently to extract otherwise wasted motion.

Need the magnets be isolated from each other or stacked in opposing orientation? I feel like stacking them complementary to each other destroys the possibility of flux lines existing outside then surface of the magnets...
