Light by bacteria

Philips's new Bio-Light concept explores the possibilities of using bacteria from household waste to power light sources.

While compact fluorescents and LEDs are certainly playing an important role is lighting systems greener and more energy-efficient, electronic manufacturer Philips are taking the quest for truly green lighting just a little bit further.

Philips have looked to fireflies and deep-sea creature to find a way to create lighting that is not supported by electricity or even solar power, but by bacteria.

The Bio-Light concept is one of the systems in Philips’s Microbial Home initiative. As such, the Bio-Light is a lighting system powered by the waste that a typical household generates.

Bio-Lights consists of different hand-blown glass compartments. Methane, which would be generated by the Microbial Home kitchen bio-digester from vegetable scraps, would be funneled along the thin silicon tubes of the bio-light, to a reservoir at the base of the object.

The light produced by this bacteria would be luminescent (cool), as opposed to glowing incandescent light. The living bacteria in the bio-light is able to produce light as long as the necessary nutrients are available.
