Here's a task for you to try: Go check your encyclopedia to find the answers to the following questions: (The answers are given in parentheses)
In fact, while you're at it, check to see who discovered the fluorescent bulb, neon lights, speedometer, the automobile ignition system, and the basics behind radar, electron microscope, and the microwave oven. Chances are that you will see little mention of a guy named Nikola Tesla, the most famous scientist in the world at the turn of the century. In fact, few people today have ever heard of the guy. Good old Tommy Edison made sure of that. After all, Tesla was considered an eccentric who talked of death rays that could destroy 10,000 airplanes at a distance of 250 miles, claimed to be able split the Earth in two, believed that both voice and image could be transmitted through the air (in the late 1800's), and essentially told Edison to take his DC electrical system and stick it you know where. In other words, anyone that has even heard of Tesla probably considers him to be a first class wacko. But, the times are a changin'. The problem is that Tesla probably could do all these things that he claimed were possible. In fact, Tesla invented every single one of the items listed above (but gets no credit) and much more. Look around you and chances are Tesla is somehow responsible for most of the things that make modern life so modern. No doubt about it, Nikola Tesla is the greatest mind since Leonardo da Vinci. So who is this genius? Little Nicky Tesla was born in Smijlan, Croatia way back in 1856. He had an extraordinary memory and spoke six languages. He spent four years at the Polytechnic Institute at Gratz studying math, physics, and mechanics. What made Tesla great, however, was his amazing understanding of electricity. Remember that this was a time when electricity was still in its infancy. The light bulb hadn't even been invented yet. When Tesla first came to the United States in 1884, he worked for Thomas Edison. Edison had just patented the light bulb, so he needed a system to distribute electricity. Edison had all sorts of problems with his DC system of electricity. He promised Tesla big bucks in bonuses if he could get the bugs out of the system. Tesla ended up saving Edison over $100,000 (millions of $$$ by today's standards), but Edison refused to live up to his end of the bargain. Tesla quit and Edison spent the rest of his life trying to squash Tesla's genius (and the main reason Tesla is unknown today). Tesla devised a better system for electrical transmission - the AC (Alternating Current) system that we use in our homes today. AC offered great advantages over the DC (Direct Current) system. By using Tesla's newly developed transformers, AC voltages could be stepped up and transmitted over long distances through thin wires. DC could not (requiring a large power plant every square mile while transmitting through very thick cables). Of course, a system of transmission would be incomplete without devices to run on them. So, he invented the motors that are used in every appliance in your house. This was no simple achievement - scientists of the late 1800's were convinced that no motor could be devised for an alternating current system, making the use of AC a waste of time. After all, if the current reverses direction 60 times a second, the motor will rock back and forth and never get anywhere. Tesla solved this problem easily and proved everyone wrong. He was using fluorescent bulbs in his lab some forty years before industry "invented" them. At World's Fairs and similar exhibitions, he took glass tubes and molded them into the shapes of famous scientists' names - the first neon signs that we see all around us today. I almost forgot - Tesla designed the world's first hydroelectric plant, located in Niagara Falls. He also patented the first speedometer for cars. Word began to spread about his AC system and it eventually reached the ears of one George Westinghouse. Tesla signed a contract with Westinghouse under which he would receive $2.50 for each kilowatt of AC electricity sold. Suddenly, Tesla had the cash to start conducting all the experiments he ever dreamed of. But Edison had too much money invested in his DC system, so Tommy did his best to discredit Tesla around every turn. Edison constantly tried to show that AC electricity was far more dangerous than his DC power. Tesla counteracted by staging his own marketing campaign. At the 1893 World Exposition in Chicago (attended by 21 million people), he demonstrated how safe AC electricity was by passing high frequency AC power through his body to power light bulbs. He then was able to shoot large lightning bolts from his Tesla coils to the crowd without harm. Nice trick! When the royalties owed to Tesla started to exceed $1 million, Westinghouse ran into financial trouble. Tesla realized that if his contract remained in effect, Westinghouse would be out of business and he had no desire to deal with the creditors. His dream was to have cheap AC electric available to all people. Tesla took his contract and ripped it up! Instead of becoming the world's first billionaire, he was paid $216,600 outright for his patents. In 1898, he demonstrated to the world the first remote controlled model boat at Madison Square Garden. So you can thank Tesla for the invention of those remote controlled planes, cars, and boats (and televisions!), also. Tesla had a dream of providing free energy to the world. In 1900, backed by $150,000 from financier J.P. Morgan, Tesla began construction of his so called "Wireless Broadcasting System" tower on Long Island, New York. This broadcasting tower was intended to link the world's telephone and telegraph services, as well as transmit pictures, stock reports, and weather information worldwide. Unfortunately, Morgan cut funding when he realized that it meant FREE energy for the world. Many stories claim that the U. S. government destroyed the tower during World War One for fear that the German u-boat spies would use the tower as a landmark to navigate by. In reality, Tesla ran into financial trouble after Morgan cut funding for the project and the tower was sold for scrap to pay off creditors. The world thought he was nuts - after all, transmission of voice, picture, and electricity was unheard of at this time. What they didn't know was that Tesla had already demonstrated the principles behind radio nearly ten years before Marconi's supposed invention. In fact, in 1943 (the year Tesla died), the Supreme Court ruled that Marconi's patents were invalid due to Tesla's previous descriptions. Still, most references do not credit Tesla with the invention of radio. (Sidenote: Marconi's radio did not transmit voices - it transmitted a signal - something Tesla had demonstrated years before.) At this point, the press started to exaggerate Tesla's claims. Tesla reported that he had received radio signals from Mars and Venus. Today we know that he was actually receiving the signals from distant stars, but too little was known about the universe at that time. Instead, the press had a field day with his "outrageous" claims. In his Manhattan lab, Tesla made the earth into an electric tuning fork. He managed to get a steam-driven oscillator to vibrate at the same frequency as the ground beneath him (like Ella Fitzgerald breaking the glass with her voice in those old Memorex commercials). The result? An earthquake on all the surrounding city blocks. The buildings trembled, the windows broke, and the plaster fell off the walls. Tesla contended that, in theory, the same principle could be used to destroy the Empire State Building or even possibly split the Earth in two. Tesla had accurately determined the resonant frequencies of the Earth almost 60 years before science could confirm his results. Don't think he didn't attempt something like splitting the Earth open (well, sort of). In his Colorado Springs lab in 1899, he sent waves of energy all the way through the Earth, causing them to bounce back to the source (providing the theory for today's accurate earthquake seismic stations). When the waves came back, he added more electricity to it. The result? The largest man-made lightning bolt ever recorded - 130 feet! - a world's record still unbroken! The accompanying thunder was heard 22 miles away. The entire meadow surrounding his lab had a strange blue glow, similar to that of St. Elmo's Fire. But, this was only a warm-up for his real experiment! Unfortunately, he blew out the local power plant's equipment and he was never able to repeat the experiment. At the beginning of World War I, the government desperately searched for a way to detect German submarines. The government put Thomas Edison in charge of the search for a good method. Tesla proposed the use of energy waves - what we know today as radar - to detect these ships. Edison rejected Tesla's idea as ludicrous and the world had to wait another 25 years until it was invented. His reward for a lifetime of creativity? The prized (to everyone but Tesla) Edison Medal! A real slap in the face after all the verbal abuse Tesla took from Edison. The stories go on and on. Industry's attempt (obviously very successful) to purge him from the scientific literature had driven him into exile for nearly twenty years. Lacking capital, he was forced to place his untested theories into countless notebooks. The man who invented the modern world died nearly penniless at age 86 on January 7, 1943. More than two thousand people attended his funeral. In his lifetime, Tesla received over 800 different patents. He probably would have exceeded Edison's record number if he wasn't always broke - he could afford very few patent applications during the last thirty years of his life. Unlike Edison, Tesla was an original thinker whose ideas typically had no precedent in science. Unfortunately, the world does not financially reward people of Tesla's originality. We only award those that take these concepts and turn them into a refined, useful product. Scientists today continue to scour through his notes. Many of his far flung theories are just now being proven by our top scientists. For example, the Tesla bladeless disk turbine engine that he designed, when coupled with modern materials, is proving to be among the most efficient motors ever designed. His 1901 patented experiments with cryogenic liquids and electricity provide the foundation for modern superconductors. He talked about experiments that suggested particles with fractional charges of an electron - something that scientists in 1977 finally discovered - quarks! Wow! Maybe now, history will now finally recognize a true genius when it sees one! |
