"Mankind must put an end to war before war puts an end to mankind."
-John F. Kennedy
Man has seen thousands and thousands of wars. He killed thousands, conquered thousands and still ready to fight another thousand battles.
They fought themselves for land, water, money and even for fame.
Thomas Edison and George Westinghouse, who, more than a century ago, engaged in a nasty battle over alternating and direct current, known as the “War of Currents”.
After Edison developed the first practical incandescent light bulb in 1879, supported by his own direct current electrical system, the rush to build hydroelectric plants to generate DC power in cities across the United States practically guaranteed Edison a fortune in patent royalties. But early on, Edison recognized the limitations of DC power. It was very difficult to transmit over distances without a significant loss of energy, and the inventor turned to a 28-year-old Serbian mathematician and engineer whom he’d recently hired at Edison Machine Works to help solve the problem. Nikola Tesla claimed that Edison even offered him significant compensation if he could design a more practical form of power transmission. Tesla accepted the challenge. With a background in mathematics that his inventor boss did not have, he set out to redesign Edison’s DC generators. The future of electric distribution, Tesla told Edison, was in alternating current where high-voltage energy could be transmitted over long distances using lower current miles beyond generating plants, allowing a much more efficient delivery system. Edison dismissed Tesla’s ideas as “splendid” but “utterly impractical.” Tesla was crushed and claimed that Edison not only refused to consider AC power, but also declined to compensate him properly for his work.
Within a year, Westinghouse Electric began installing its own AC generators around the country, focusing mostly on the less populated areas that Edison’s system could not reach. But Westinghouse was also making headway in cities like New Orleans, selling electricity at a loss in order to cut into Edison’s business.
When New York State sentenced convicted murderer William Kemmler to death, he was slated to become the first man to be executed in an electric chair. Killing criminals with electricity “is a good idea,” Edison said at the time. “It will be so quick that the criminal can’t suffer much.” He even introduced a new word to the American public, which was becoming more and more concerned with the dangers of electricity. The convicted criminals would be “Westinghoused.”
To further demonstrate the lethal nature of alternating current, he held a widely attended spectacularly in Coney Island, New York, where a circus elephant named Topsy was to be executed after she was deemed to be too dangerous to be around people. The elephant had killed three men in recent years—one a trainer who had tried to feed Topsy a lit cigarette. Edison had Topsy fitted with copper-wire sandals, and before a crowd of thousands, an AC current of 6,000 volts was sent coursing through the elephant until she toppled to her side, dead.
