Edison's Failed Inventions
Edison had 1,093 patents for different inventions. Many of them, like the light bulb, the phonograph, and the motion picture camera, were brilliant creations that have a huge influence on our everyday life. However, not everything he created was a success; he also had a few failures.

One concept that never took off was Edison's interest in using cement to build things. He formed the Edison Portland Cement Co. in 1899, and made everything from cabinets (for phonographs) to pianos and houses. Unfortunately, at the time, concrete was too expensive and the idea was never accepted. Cement wasn't a total failure, though. His company was hired to build Yankee Stadium in the Bronx. What else do you think Edison tried to create?
