the Edison direct-current generator


Did famous Edison invent this?


Yes. It was used to light an electric light bulb.

Really? What is an electric light bulb by the way?  
  An electric light bulb means a so-called ordinary bulb and it is different from a fluorescent bulb. In order to create a long-lasting bulb, Edison had searched for appropriate material for filament, a part of a bulb that glows to give off light.
I see. Did he find it?  
Yes, he found out that bamboo in Kyoto was best suitable.
Wow! It is surprising that Japan made great contribution to the practical use of an electric light bulb.  
Thomas Alva Edison, known as the inventor of practical incandescent lamps, also developed various devices to power electric lamps such as a direct-current generator. Direct-current generators, which were manufactured and sold by Edison Machine Works in those days, were built on the same basic design but they came in several types with different outputs to serve different purposes. This generator is a typical example of the lineup and the same type as the generator used for electric lighting at the Shimotsuke Linen Spinning Company's spinning mill in 1890. The Edison generator, which was used at Tokyo Electric Light Co.'s Electric Light Station, was the No. 10 generator and had a larger generating capacity than the exhibit, with an output of 25 kW.
