Electromagnetic Railway

Biography

Thomas Alva Edison was born in Ohio in the United States, was a businessman, inventor and scientist who lived between 1847 and 1931. There is an extensive list of patented objects on your behalf and that if did not get to come true in life at least the basis for something later was created.
He was the creator of the incandescent light bulb, its great and recognized invention. In addition, objects like tattoo pen, vacuum packaging, rubber wheels, X-ray machine and even video cameras were designed by the inventor.

Electromagnetic Railway

 Although not applied in Brazil, electric trains and subways are widely used in major cities in the world for passenger and cargo back and forth.
Electromagnetic irons roads emerge as effective and clean alternative for urban mobility and also for transit between cities, states and countries around the world. On May 13, 1880, Thomas Edison was the first test of his road electric iron in Menlo Park, United States.
For over 130 years, so when sustainability and alternatives to fossil fuels were not as on the agenda, the scientist already started an idea that floraria years later in various parts of the world. The largest cities in the world with electric trains and subways to carry passengers and cargo from one side to another.









However, with the technology that we have rails and trains as what Thomas Edison designed become increasingly "outdated". Nowadays we can ride on trains to even touch the ground. The Union between advanced technology and physics allows the train to move by magnetic fields, called magnetic levitation.
           The train (train) of magnetic levitation or Maglev (Magnetic levitation transport) is propelled by the attractive and repulsive forces of magnetism through the use of superconductors. The lack of direct contact with the rail, how does the conventional trains, the only force of friction that exists is between the train and the air, which provides relatively low energy consumption, little noise and very high speeds.




The first commercial train that uses this technology made its maiden voyage in 2002 in China. The project was imported from Germany, being able to reach a speed of 501 km/h connecting Shanghai to the Pudong International Airport.
           In April 2015, the Maglev train is operated by Central Japan Railway Company in Japan slammed his own world record of speed upon reaching 603 km/h.
