I don't think that this is quite a good idea. The weight feels a little too heavy to hang on a wall consistently, and the mechanisms are a bit too intricate. I'm also not sure the string would take that much weight, and because the weight falls slowly it might be prone to being stalled. I think it's easier to have a hand-cranked lamp that recharges a battery, which is probably much cheaper and easy to use.
