You might think that dead batteries become useless as soon as they're unable to power your gadgets, but they can actually still be used as a power source for street lights. The Energy Seed, designed by Sungwoo Park and Sunhee Kim, utilizes this phenomenon brilliantly.
Energy Seed is an LED street lamp that uses trashed alkaline batteries. Most people just throw away batteries together with their other waste, which poses an enormous environmental problem since traditional batteries feature environmentally harmful metals and chemicals. As these batteries degrade, their toxins go right into the soil.
With Energy Seed, people within the vicinity are encouraged to deposit their dead batteries in the lamp. The street lamp has slots for all sizes of alkaline batteries. The lamp lights using the combined power left in all the batteries. Your single battery may not be able to power up your remote control, but when collected and used with other batteries, the energy would be enough to make your street bright at night.
When all the batteries inside the Energy Seed are used up, they will be properly collected and delivered to the right recycling centers.
