In 1901, a lightbulb was installed at the hose cart house in Livermore California. Except for a 22-minute period during a move to a new firehouse in 1976, the bulb has remained lit continuously the entire time. “Hanging 18 feet above the floor at the end of a black cloth-covered cord, the little light with the filament the width of a No. 2 pencil lead is unprotected by any lampshade. Firefighters won’t even dust it. Touch it, jokes one captain, and you get your fingers chopped off.” The light bulb has a website, but unfortunately, it looks like it’s currently down, showing just a plain page with an email address.
