"Tesla had a keen memory and ability to visualize and construct complicated objects in his mind's eye. While working on his first job with the American Telephone Company in Budapest in 1880, Tesla suffered a nervous breakdown in which he claimed to suffer from a Edgar Allen Poe-like hypersensitivity of perception (Hunt and Draper 1991, p. 32). After he recovered, he was walking with a friend when the idea for the polyphase system of generating alternating current suddenly occurred to him. As of yet, he did not possess the means to actually build the necessary equipment........"

We know that he was undoubtedly persecuted by the energy power brokers of his day -- namely Thomas Edison, whom we are taught in school to revere as a genius. He was also attacked by J.P. Morgan and other "captains of industry." Upon Tesla's death on January 7th, 1943, the U.S. government moved into his lab and apartment confiscating all of his scientific research, some of which has been released by the FBI through the Freedom of Information Act...

In the realm of electrical engineering the name of Tesla stands out most prominently above almost all others in the present age. The achievements of this singular individual, in particular his discovery and mastery of Alternating Current, practically created the modern world, bringing power to the people in all countries, including global communications. In his field Tesla was the pioneer. And his research greatly advanced the technologies responsible for generating and distributing power, both of great magnitude and also over great distances. Indeed, his particular interest in this regard was to develop ways of actively transmitting power wirelessly; something that he did indeed manage to achieve during his work, as is well documented.....

Of all the great inventions and discoveries of Nikola Tesla, nothing stood out with greater potential benefit to the whole of humanity than his discovery of Radiant Energy in 1889. The series of observations that led to the discovery of Radiant energy initially grew out of experiments that Tesla had conducted in an attempt to duplicate the results that Heinrich Hertz had claimed to achieve in affirming the existence of electromagnetic waves, the discovery of which Hertz announced in 1887. While replicating Hertz’s experiments...
