Three years to the date after Nikola Tesla delivered a famous lecture to the American Institute of Electrical Engineers outlining the efficient production of electricity from a centralized location and transmitting the power generated over long-distances using alternating current, the International Electrotechnical Exhibition opened at Frankfurt’s Westbahnhof and demonstrated the first such inductive feat, the power generated from a hydroelectric source some one hundred and seventy five kilometres south from a waterfall at Lauffen am Neckar. The Post Office helped erect the transmission lines, a considerable amount of copper wire—the three phase arrangement (3ฯ†) that is used for most modern grids to this day trebling or rather thirding voltage across three wires each with the current offset by one hundred twenty degrees—that retained about three-quarters of the output over the distance, the experiment proving that generation in situ, with direct current, was not ideal in most domestic and industrial applications, confirmed and adopted by the United States and favouring rival George Westinghouse (Tesla’s employer) over Thomas Edison in the War of the Currents at the Columbian Exposition in 1893.
