LED Pendant Powered by Living Organisms

Dutch designer Teresa van Dongen has created Spark of Life, an LED pendant powered by bacteria. The bacteria are electrochemically active, producing sufficient current to power the LEDs and produce light. The vessels need to be cleaned and refilled with water, salt and vitamins periodically, while the bacteria remain in the electrode. Van Dongen is hoping to turn the idea into an environmentally friendly product.

    This is very impressive. Hopefully, she will concentrate on developing larger cells, where the required electrolytes, vitamins and other required components are added automatically and any waste product are removed automatically.
