No real title just kind of spacing out and rambling on...

While getting power from blood isn't exactly new (dracula) and human batteries aren't new either (Matrix), actaully getting electrical current from a human body is quite novel. According to the story you could power 1000 watts or enough to power a lightbulb.
Based on this hand cranked charger for a Sony Play Station Game Boy, my question is could you reverse engineer this to increase a person's energy level by adding a hand crank charger to them? More seriously though a plugin port where one could draw temporary or low amounts of currency could be pretty handy.
