Nintendo DS wind-up battery charger: pointless or not?

We should all think about the environment and when I see a product like this wind-up battery charger for the Nintendo DS, you got to look more into it.

Do you think it’s a pointless idea or not?

It may take a while to get the full power up and the sound it makes is pretty annoying, but one gamer said they would mod it to wind while biking…that’s a great idea.
