Electrochemically active bacteria can emit small electrical currents in their metabolism while cleaning waste water. I explored these specific bacteria as a means to generate electricity for domestic use. The research led me to develop Spark of Life, a lamp that emits light without the need of a plug. This "living lamp" only needs a teaspoon of acetate every two weeks and some new water every month. A tiny bit of nourishment in return for energy and light. I imagine that having to feed and thus take care of your lamp could result in a closer relationship between the lamp and its user.
