i've been seeing a lot of hand-powered flashlights lately, that only give 1 or 2 watts of power, but you crank it for 30 - 60 seconds for 1 hour of juice. i think the brightness would help to be seen at night but not to see at night. has anyone ever seen one with a handlebar mount? it sounds like they'd be great as a last-resort backup when your main light(s) batteries die and you are caught without spares. i saw one that also has a cell phone charger that is powered by the hand crank too, and an alarm, and a radio, etc...
