The Ugly Truth About Thomas Edison When I was in secondary school, I was involved in a play about Thomas Edison. And so I decided to do a little bit of research even though at that time I already knew a lot about him, because he was one of the greatest inventor that I'd ever known. But the result from the research that I conducted expose the ugly truth about him, that he wasn't the hero that people thought he was. The rivalry between him and Nikola Tesla, eventually revealed his true colours. It started when, Nikola Tesla migrated to America to work with his hero, Edison. Tesla soon discovered that Direct Current (DC) that was invented by Edison has a flaw. DC current could only supply current at a distance of 1 mile in any direction. This would mean that a substation have to be built every 2 miles to supply sufficient current. This would result a massive pollution to the world. Tesla quit his job and invented a new generating current that is known as Alternating current (AC). (the current our household use today). THE WAR OF CURRENTS. Edison soon saw Tesla as a threat to his business. He then plotted and evil plan to sabotage Tesla's invention by electrocuting several animals to falsely proof that AC current is dangerous to the public. NIKOLA TESLA. Nikola Tesla was an inventor who invent for the love of science and for the good of mankind. He even wanted to create FREE electricity. Imagine a world with free electricity, everything would be so different. But his investors didn't see the profit they would make if it was for the purpose to provide something for free, so they stop investing to Tesla's experiment. Although Edison was a terrible man, we need to remember that he invented motion picture (videos), light bulbs and batteries. He's also the reason why we greet someome on the phone with "Hello" instead of "Ahoy" (otherwise we all would sound like a pirate). Thomas Edison was a very good businessman and unfortunately, a guy who couldn't accept defeat very well.
