Interesting story on how First transmission happened through wire:
In 1873, at the Vienna (Austria) exhibition, circumstances led Hippolyte Fontaine to realize in public the first industrial application of the electrical transmission of forces.
Hippolyte Fontaine is doubly present in Austria under the Société Gramme of which he is the administrator and which exposes his current generating machines and inventor of small domestic engines.
When he was not yet forty, his encounter with the Belgian inventor Zénobe Gramme after the 1870 war was decisive for his future. The latter was looking for a sponsor to exploit the patent he had just filed and which concerned a machine generating direct current. The Count of Ivernois, administrator of the Docks de Saint-Ouen, a company in which Fontaine had worked as an engineer responsible for works before the Franco-German war, had agreed to sponsor the creation of the new magneto-electric machine company Gramme. Fontaine was appointed director. These two men of so different origin were made to understand each other and to esteem themselves:one, Gramme, had the temperament of the inventor, the other, Fontaine, that of the director and the industrialist , this is the secret of the exceptional success of their association, which lasted more than thirty years and the newly created company was going to grow very fast.
The Company has two Gramme machines, a generator generator for electroplating, powered by a gas engine, and another receiver powered by a battery bank to set in motion a centrifugal pump operating a waterfall. This last device aims to show the reversibility of the dynamo, which Fontaine has just highlighted.
The Emperor of Austria having announced his visit, the battery of batteries is unfortunately down. Fountain having only the generator generator to power the second dynamo, but whose operating voltage is much lower than the voltage of the first, the idea of causing a voltage drop by inserting a cable of copper between long enough, two kilometers, until the pump runs at its normal speed: it has just shown that it is possible to transport energy while production and use of electricity were confined until then in the same places.
