This lamp is powered by electrochemically active bacteria that require regular feeding of acetate and water to survive. Inside a microbial fuel cell, bacteria emit electrical currents and exchange electrons with an electrode. The electrode powers 3 light-emitting diodes that produce a sustained, dim glow. The living lamp and its owner have a symbiotic relationship in which the lamp provides illumination, but only if the bacteria are nurtured.
