Street lamps powered by discarded batteries light the neighborhood for cheap

That battery you're throwing away may not have enough energy left to power your gadgetry, but it does have enough juice to light up a low-energy LED. That's the driving idea behind South Korean designer Sung Woo Park's conceptual Energy Seed, a stylish street lamp powered entirely by discarded batteries.

Drop a battery into one of the Energy Seed's disposal holes and it'll fall down into a tube. Several batteries can be stacked one on top of the other, daisy-chaining drained batteries into a long-lasting power supply for an LED lamp that will give pedestrians a bit of light on the sidewalk. It's a great way to re-appropriate trash that we'd otherwise consider useless.
