The light bulb - and the market for it ... "world's first economically viable system of centrally generating and distributing electric light, heat, and power."Edison invented the first practical Dictaphone, mimeograph, and storage battery. After creating the "kinetiscope" and the first silent film in 1904, he went on to introduce The Great Train Robbery in 1903, which was a ten minute clip that was his first attempt to blend audio with silent moving images to produce "talking pictures."
Thomas Edison's light bulb was special because it was one of the first practical and commercially viable electric light sources. His improvement over earlier designs included a carbon filament that could last for over 1,200 hours, making it more durable and efficient. Edison's development of a complete electrical system, including generators and wiring, allowed for widespread adoption of electric lighting, transforming everyday life and paving the way for modern electrical infrastructure.
Thomas Edison built his first lab at age 10 ten.
The first solar battery was used for generating electricity power for some specific works, jobs and functions, which were to be required the power for completion of their targets and works.

1. Marion Edison is Thomas Edisons older sister. 2. Marion Estelle Edison Oeser is Thomas Edison's first child.
That was the alternate current which put to Edison electric monopoly in the late 1800s.
Thomas Edison's first successful light bulb lasted for about 13.5 hours when he first demonstrated it. However, he and his team later improved the design to last for over 1500 hours.
No, the first light bulb that Thomas Edison invented is not still operational. Over time, light bulbs burn out and lose their ability to produce light due to the filament burning out. However, Edison's invention laid the foundation for modern lighting technology.

Edison invented both the incandescent light bulb and the first phonograph.
To measure Mark McGwire's home run distances.
Thomas Edisons phonograph (gramophone) was the first device invented that could play recorded audio. The first sound recording device was the phonautograph, invented by Eduoard Leon-Scott in 1857, people had also found was to record audio onto foil, but the phonograph was the first audio reciprocation device.
