LoneWlf794 Bigger Weight? (596 comments)

I think my laptop would require a slightly larger weight to pull this off.
Of course I didn't RTFA, but I assume that as the weight is descending some sort of friction is being produced, which in turn produces your electrical charge. So wouldn't it make sense to have many smaller weights instead of one larger one?
