Eco-Clock by Bor-Ru Huang
The Eco Clock is a brilliant way to make sure we extract every bit of juice from a discarded AA battery. There are 12 slots on the face of the clock to host the used batteries and collectively they power the device. The design also includes a really fun feature where the different levels of juice in each battery are represented by color. Neat.
