A scientist ahead of his time – Nikola Tesla
Nikola Tesla – a genius whose inventions we use every day without realizing it. Next we are going to tell you a little about the most significant discoveries of the scientist.
Alternating current (AC)
Nikola Tesla was the first to discover that AC can serve as both an energy carrier and an information carrier (for example, audio or a radio signal). Of course, this signal must first be modulated. Today the European electricity distribution network is managed with single-phase AC 50 Hz and with a voltage of 220 Vz.
The Tesla coil is made up of a series of Tesla turbines that create electrical discharges with a range of the order of several meters. These discharges resemble lightning during a thunderstorm. In 1998 Stanford engineer Greg Leigh demonstrated to the audience the effect of the Tesla coil with lightning "on demand," which is produced in a metal cage. With the help of a metal bar "the magic stick" he created, managed and modified the downloads as he pleased. He recently started a campaign to raise funds for the construction of two towers in the US (similar to the one Tesla was trying to build back in the day) The project is expected to cost more than 6 million dollars.
Nikola Tesla wanted to create a world system for the wireless transmission of electrical energy based on electrical conductivity (the ability of a material to let the electric current free). In early 1891 he claimed to have demonstrated the wireless transmission of energy. However, he was never able to put it into practice in an efficient way.
Nikola Tesla Museum in Belgrade
The “Nikola Tesla” museum is located in the center of Belgrade. It has more than 160,000 original documents, more than 2,000 books and magazines, as well as more than 1,200 technical exhibitions, 1,500 original images of his technical creations, instruments and devices, more than 1,000 plans and drawings, all of them related to the life and work of Nikola Tesla. I entered the UNESCO list in 2003.
Today it is the only museum in the world that keeps original documents and personal belongings.
