Who invented the radio?
Go check your encyclopedia to find the
answers to the following questions:
(answers are given in parentheses)
1) Who invented the radio? (Marconi)
2) Who discovered X-rays? (Roentgen)
3) Who invented the vacuum tube amplifier? (de Forest)
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 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
lightbulb 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 lightbulb, 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 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 finally recognize a true genius when it sees one!
