Would you use a wind up charger for your mobile phone?

I imagine you've seen those emergency chargers that are available for phones that give you five minutes-worth of charge. Would you be willing to sit there winding like a fool to fill the battery completely if it meant saving tons of pollution every year? Or how about a charger attatched to your stepper or static bycicle? Excercise would be even more useful!
Or how about a generator connected to your office chair. If an automatic watch gets wound by the movement of a wrist, how much energy would be generated by the whole country when it turns to get up and get coffee?
Let me rephrase, would you be willing to commit a bit of elbow grease to save the planet a little bit more in exchange for having modern technology?
