In 2012, 100-watt incandescent bulbs will be a thing of the past, but fear not, as there's some great energy-efficient lightbulb tech to illuminate the way. It ranges from compact fluorescent lights to LEDs to halogen bulbs, and, if Philips has anything to do with it, bacteria-powered lights.
The system uses bioluminescent bacteria that feeds on methane and composted material to produce a soft green light, not all that different from the light emitted by fireflies and red tide.
The bacteria is housed in a wall of hand-blown glass cells and connected to a food source at the base through thin silicon tubes. The bacteria's food source comes in the form of methane gas, which is converted from solid bathroom waste and vegetable trimmings using the methane digester located in Philips' bio-digester kitchen island--the main hub of the Microbial Home.
The Bio-light could be "powered on" as long as there were a supply of nutrients, but the resulting light isn't bright enough to illuminate an entire room. Instead, Philips sees the Bio-light as more of an ambient light source, as well as a way to power night-time road markings, warning strips for planes and stairs, and more.
