Nikola Tesla was certainly an eccentric scientist, but many believe that his inventions were more prominent than the invention of Alexander Graham Bell and Thomas Edison. His electric car, exuberant imagination and eccentric style became a symbol of "a crazy genius».
1. The wireless power
About 120 years ago, in 1893 at the World Exhibition in Chicago, Tesla demonstrated wireless power, sparking a series of phosphoric light bulbs in a process called electrodynamic induction. He dreamed that one day this technology will help us to transmit electricity over long distances in the atmosphere, providing remote areas with the necessary energy for a comfortable stay.
Now, after more than a century, large companies such as Intel and Sony are interested in using the nonradiative energy transfer to such things as mobile phones, so that we can charge the battery without the power supply wiring.
Research Tesla in the field of electromagnetism helped radiologists around the world to see the human anatomy without having to rip open his stomach. However, at the end of the 1880s, this idea seemed quite insane.
Although the discovery of X-rays attributed to German physicist Wilhelm Roentgen in 1895, Tesla was in his experiments with this technology for eight years before Roentgen noticed some danger of radiation for human flesh.
3. Death Ray
In 1930 Nikola Tesla, according to some allegations, he invented a weapon of the particle beam, which is called the "death ray." In theory, the device could generate intense directed beam of energy that could be used to destroy enemy aircraft, army and other stuff. However, the "death ray" was never released by Tesla, although he tried to sell it to various military units.
