Thomas Edison is remembered for his contributions to many great innovations, including the phonograph, the light bulb, and the movie camera. But few people today remember one of his most spectacular failures: a talking doll that was the must-have Christmas toy in 1890. There was just one little problem with the dolls. They sounded like they were possessed by demons.

This is the oldest recording of an American voice and the first-ever recording of a musical performance. Recorded by a Thomas Edison-invented phonograph in 1878, the audio recording (which lasts 78 seconds) is pretty much “as far back as we can go” in terms of the history of recorded sound. More »
A Berkeley Lab research team in California has successfully restored a 134 year-old audio recording. The historic audio was originally captured in 1878 by a phonograph designed by Thomas Edison, which consisted of a cylinder wrapped in tinfoil that used a stylus to record sound on the surface of the material. Due to the foil’s frailty, recordings were only good for a few playbacks on Edison’s phonograph. To restore this century-old mixtape, the research team created a 3D model of the grooves in the foil and ran it through a software that recreated the original audio track. As for the great mystery of the recording’s contents, it’s a 23-second horn instrumental followed by what is believed to be political writer Thomas Mason reciting Mary Had a Little Lamb and Old Mother Hubbard. Using modern technology for playback, the restored recording is set to have a listening party this week at the Museum of Innovation and Science in New York.

Back in the 1920s, Thomas Edison’s dream of an electric automobile was ultimately foiled by those meddling petroleum engines. But thanks to nanotube research from Stanford University, one legacy from that era may regain some glory: nickel-iron batteries. It turns out that carbon nanotubes doped with nickel and iron crystals can top up the normally slow-charging cells in a matter of minutes — according to the scientists, that’s almost 1,000 times faster than in the past. Although the batteries couldn’t power your Volt or Prius due to a lack of energy density, they could give an extra jolt to their lithium-ion siblings for quicker starts and regenerative braking. The researchers are working on improving stability to allow more charging cycles, but it might be an extra in-your-face for Edison if it pans out.
