Time Your Light

Should the apocalypse ever come where you won't have any more power routed to your home, perhaps the Time Your Light concept would be very much welcome. After all, it relies on pent-up wind-up energy just like how a windup doll does. All you need to do to get some light is give it a twist, and hopefully the irritating ticking noise problem would have been solved by then. It begs the question of whether this is a timer with a light attached, or is it a mechanical light that functions just like a timer? Love the color scheme it comes in though.
