TheEdisonsystemoflighting was as beautifully conceived down to the very details, andas thoroughly worked out as if it had beentestedfor decadesinvarioustowns.
The Swach's cartridge, a key component of the system, resembles Edison's electric bulb and is made up of a composite of rice-husk ash (a highly porous material derived out of paddy husk) and fine particles of nano-silver, which inhibits bacteria growth.
But I sort of feel that, you know, if Thomas Edison were in the school system today, he wouldn't have failed 10, 000 times before that one time that he figured out the real one - you know, the answer to the question.
And James Fama, vice president for energy delivery at the Edison Electric Institute, said the system appears to have worked well, given that the lights came back on and the circuitry was not damaged.
