Your question is peculiar. He didn't use a "process". He generated electricity with a device. His generators were series wound DC generators referred to as "dynamos" at the time. The dynamos were driven by coal-fired steam engines. He manufactured all his dynamos himself and often tinkered with the engineering of them.Can anyone describe for me the process that edison originally used to produce DC when he built his original electric companies?
Tesla/Westinghouse differed not only in adopting AC for long distance transmission of power but also in being pioneers of hydroelectric systems.Coal fired steam engines was what I was wondering. Thanks. My class was watching a video on Tesla, and we were just curious.
