This Desktop Energy Seed Lamp is interesting. It uses old batteries as a power source. All of the batteries are put in parallel using two large metal plates and a jewel thief circuit (I prefer the rusty nail implementation though) is used to create the larger voltage needed to power the LED circuit.
