15 Thomas Edison's inventions that changed the world

February 11, 1847 in the town of Milan, Ohio, Thomas Alva Edison Birthplace - an incredibly successful inventor, scientist and businessman, received in 1093 for his life of the patent.

His first patent registered in Edison for 22 years. Later, in his laboratory in Menlo Park, New Jersey, he was working as productively as "hot cakes" creating revolutionary new products that once promised to issue on one small invention every 10 days and one major every six months. And although many of the discoveries attributed to him have been created by other people, in any case, Edison played a significant role in shaping the modern world. And today, we remember the most important technological advances of the American engineer, the most influenced the modern world.

The electric vote counter elections

This was the first patent of Edison. "Yes" or a device allows voters to press the button "no" instead of writing on paper. Unfortunately, the demand for this device was not - as it turns out, when you use the policy could not so shamelessly deceive present and using the rigging of the results to persuade colleagues to change their opinions. Parliament rejected the invention in favor of the usual written accounts.

Automatic Telegraph

To improve the telegraph, Edison created yet another - on the basis he invented the perforated boron - for which the person was not necessary to print the message on the other end. This new technology has increased the number of words transmitted per minute, with 25-40 up to 1000! Edison was also the inventor of the "speaking telegraph".

Elektrobor

The predecessor of the perforated boron, which makes a hole in the telegraph became elektrobor creating template for writing, which could be used to stamped ink on paper and make duplicates.

Phonograph

Phonograph record and reproduce audible sounds via first wax paper and then with a metal foil on the cylinder. Edison created many versions of a few years, more and more perfecting each of the models.

Carbon telephone

Edison perfected the weak spot telephone Alexander Graham Bell - the microphone. In the original version had a carbon rod, but Edison decided to use coal battery, which significantly increased the stability and range of the signal.

Light bulb with carbon filament

Bulb Edison carbon filament represents the first commercially convenient source of electric lighting. Previous versions were not so powerful and to make them used too expensive materials such as platinum.

electric lighting system

Edison designed his system of electric lighting, in order to maintain the same amount of electricity for the entire device. His first permanent station he established in Lower Manhattan.

Generator

Edison designed a device to control the flow of electricity between the devices - the idea has been used in many of his works, such as an incandescent lamp.

is a monograph (speakerphone)

This device is lowered electrical currents from high to low, which made it possible to transmit voice sounds over long distances and at a higher volume. Another invention of Edison - a carbon rheostat - helped create a monograph. Speakerphone Edison for several years been used in England.

The technology of fuel cells

Edison was one of many long chain inventors tried to create a modern fuel cell - a device that would produce energy by reaction between hydrogen and oxygen, leaving only water as a byproduct.

Universal printer

Although Edison did not invent the telegraph exchange, he perfected his own telegraph technology to create a versatile printer, which is faster than the existing version.

Magnetic iron ore separator

Edison designed device which shared the magnetic and nonmagnetic materials. Thus it was possible to separate the iron ore from the unsuitable low grade ores. This further development was the basis of the milling equipment.

peep show

Edison was looking for a way to create "a tool that will do the same to the eye that the phonograph to the ear." Peep show photos in quick succession, which is why it seemed as if the image moved.

alkaline battery

Experimenting with a nickel-iron battery, Edison applied alkaline solution, allowed to obtain a "long-playing" battery. This product went on to become one of the best selling.

Cement

While the cement is already existed, Edison perfected its production via rotary kiln. Development of the inventor, as well as its own company Edison Portland Cement made this product available commercially.
