Century-Old Light Bulb From Ohio Site Still Works At least one of five century-old incandescent light bulbs still works after being pulled from the cornerstone of a Cleveland-area building along with a time capsule. The Plain Dealer reports (http://bit.ly/GUrSIB) GE Lighting began a 100th anniversary celebration of the Nela Park operation on Monday at one of the park's original buildings at the East Cleveland research center. The lead-box time capsule held photos of Nela founders, journals, a book of technical specifications and a Plain Dealer. The 40-watt light bulbs were packed in sand above the box. A special socket was used to show off one bulb's longevity. The rest went to a research lab. The Nela industrial park is the headquarters of GE Lighting, and is listed as an historic place by the U.S. Department of the Interior. Information from: The Plain Dealer, http://www.cleveland.com
