Engineers at GE's NELA Park facility recently discovered five intact lightbulbs inside a 100-year-old time capsule. And much to the delight of the dudes over in marketing, three of the century-old bulbs still work.
The tungsten filament bulbs needed a little cleaning after being removed from their temporary tomb, but once connected to a socket and slowly powered up to 60-volts, the majority of them slowly came to life. They're obviously not as bright as modern bulbs which use more efficient filaments, but claiming a 100 year shelf life would be impressive even today. [GE via BoingBoing]
