Livermore's mysterious lightbulb burns 110 years »
In this transient modern world, this lightbulb is really something you can trust. [...] nobody knows the mystery of it. Inside the hand-blown glass is a jumble of carbon filament that radiates about 4 watts of soft orange light - about the strength of a nightlight. No one seemed to notice that the bulb never made that telltale pop and fade to black. [...] that changed in 1972, when an intrepid cub reporter named Mike Dunstan at the Livermore Herald News cracked the story with a lengthy investigative piece suggesting Livermore's glowing orb was possibly the oldest functional lightbulb on Earth. The bulb has been the subject of dozens of news stories, magazines, books and television shows. Dubbed the Centennial Bulb, it is a wonder among engineers and advocates of energy-efficient lightbulbs. Double-decked tour buses often stop by the fire station for viewing. Henry Slonsky, an electrical engineering student at San Francisco State, was more open-minded. Generations of firefighters have relied on the bulb's soft glow to guide them, from the days of horse-drawn carts to today's giant engines. Source Main page (current trends)
