That's not what he did. By running the load current -- not the individual dynamo currents -- through the compounding coils on all the dynamos, whether in service or not, the powerhouse can have the necessary negative resistance characteristic while the individual dynamos can behave as if they were uncompounded. The scheme uses an "equalizer bus". Pure genius! Jerry

And I never ceased to be amazed at what those guys (gals too) achieved. Edison combined his genus with a hard work ethic and business acumen to achieve many great results. Linking the generators that way is purely genus, but I bet he tried many methods until he achieved this one. It is sort of like when you see a concise mathematical proof. And you wonder how in the hell did that get figured out. But then you find out a significant amount of work preceded the final polished solution. Edison had a drive to constantly improve things. Clay

I believe that was the DC generator and motor, where someone, at a Chicago fair as I remember, had two generators hooked up and noticed that turning one would cause the other to turn. -- glen
