Use any cordless drill as a crank charger for batteries! The basic idea is to use the drill as a crank charge generator, and regulate the voltage to charge 1.2-1.5 volt batteries.
I don't hold this as the be all, end all idea, only as a starting point for discussion and development of better ideas. I'm just showing you what I was able to do using the parts mentioned, but I'm pretty happy with the results, especially as we're about to get an ice storm here that will no doubt knock out our power for a bit.
A couple of notes: The trigger MUST be held down for this to work. The drill is in reverse setting and cranked in reverse.
