Thomas Alva Edison was born February 11, 1847 in Milan, Ohio.
He was an inventor and invented something that would change the world, light bulb.
Before the light bulb he invented the phonograph which is a simple kind of gramophone. It was, according to him his best invention, but the update, the real phonograph invented a German inventor named Berliner.
Thomas's first major invention was an automatic counting machine that counted the votes in political elections, but politicians did not like the idea and Thomas decided to never again do something no one liked.
Thomas Alva Edison
Even in elementary school, Thomas was smart and questioned a lot, the teachers got fed up and Thomas was taught by her mother at home.
After a few years, Thomas was already smarter than her mother and instead sat all day and self-taught through books.
At 12 years of age he began to work on a train where he sold newspapers and edible things. After many interviews got Thomas a job at a telegraph station when he was 15 years old. But after a few years he quit to devote all his time to inventions.
He failed to invent something useful until he was 20 years old when he was a small change at the Telegraph, exchange Telegraph. He took out a patent on the invention, and with the money he got, he bought a small shop in New Jersey. He used the workshop as laboratory and got money from the little things he made. The shops started to go a bit dull so he thought it was due to the workshop. With help from his father, he built a new laboratory, also in New Jersey. He hired some inventors assistants and began inventing things full time.
People found out what he did and gave ideas and orders inventions.
He did what people said and made a lot of money. He expanded on Bell's telephone so that you could talk with a normal voice with each other.
With all the money he started, he employed 50 staff to.
If Thomas felt he was close to inventing something work he sometimes several days at a stretch and sometimes he managed to say things that have changed history.
He made a rule in his workshop that every tenth day invent something small and every six months invent something great that he wanted to become world famous. How much money did Thomas than for his inventions, he worked not for money, he thought it was funny and wanted to give people things that would make life easier.
1913 Thomas Edison invented the light bulb today with tungsten wire and glass.
Thomas la several years to just find the right thread.
He bought several thousands of different threads that he thought would keep.
When he and his co-working Joseph Swan tested frock councils managed to keep them off the bulb for about 45 hours straight. But when a messenger boy would give Thomas bulb, he dropped it and the only example was addressing. Thomas did not care so much because he wanted to make the bulb last even longer, so he went looking for the right thread.
Thomas was still worrying because he did not like the idea that everyone should have a generator in the house and replacing the bulb all the time. So he invented the electric utility. It was built a large power stations in the city and when the generator was ready succeeded Thomas find the right thread. He hung up a few bulbs outside the house and the newspapers and the people of the town were astounded how long they held.
Thomas continued testing wires and finally he came to the tungsten wire, a wire that can withstand high heat for long. Hand bulb became a world sensation, and Thomas became acclaimed by the world as history's best inventor. The bulb was begun used around the world and that people could start working at night was the best found many.
The bulb today
Even today, the same kind of light bulb around the world and it had been difficult to manage without the bulb.
The tungsten filament is in the glass because if tungsten in contact with oxygen burns thread up in seconds.
Now in the 2000s, there are dozens of different kinds of lights to choose from, from the bulb to the UV lamps. But how many lights there than there are many agree that the bulb is still the best and will be on top for long.
The use of the bulb does no harm to the environment but ordinary bulbs consume a lot of energy, but there is a dangerous metal in the socket named lead.
The bulbs in Sweden is the largest source of lead emissions in nature.
20001 became law in Sweden that the bulbs are collected and recycled.
And sooner when using candles and it was very expensive in the long run because they had to buy new lights all the time.
And when tungsten is dug out you have to open large mines and dig, it's not good for the environment and the greenhouse effect much because of all the machines and all the exhaust gases.
The electricity that we get to bulb manufactured in wind turbines, hydropower and so on. But electricity is also produced by nuclear power plants that are extremely bad for the environment. But now there are not many nuclear plants there for people understand that it's not smart to destroy the environment.
