We might complain that it's 2015 and we're still waiting on our hoverboards. But if Nikola Tesla were alive today, he'd probably wonder where the hell our fuel-free, super fast airplanes were. And who could blame him? Fuel-free planes aside, he actually predicted a lot of 21st century technologies quite accurately.
The January 30, 1926 issue of Collier's magazine included an interview with the legendary inventor. In it, Tesla relayed his amazing predictions for the future — a world of flying machines, wireless power, and female superiority. Some of the predictions were spot on. Others, not so much.
Tesla on TV and portable phones
July 1922 cover of Science and Invention imagining broadcast TV
At the beginning of 1926, when this interview with Tesla was published, television was barely making its first baby steps. But Tesla was already looking into the distant world of videophones, broadcast TV, and worldwide mobile communication.
When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do his will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket.
We shall be able to witness and hear events—the inauguration of a President, the playing of a world series game, the havoc of an earthquake or the terror of a battle—just as though we were present.
When the wireless transmission of power is made commercial, transport and transmission will be revolutionized. Already motion pictures have been transmitted by wireless over a short distance. Later the distance will be illimitable, and by later I mean only a few years hence. Pictures are transmitted over wires—they were telegraphed successfully through the point system thirty years ago. When wireless transmission of power becomes general, these methods will be as crude as is the steam locomotive compared with the electric train.
Wireless transmission of power was of particular interest to Tesla, but it's his predictions around mobile phone technology that have proved most prescient here in the early 21st century.
Tesla on flying machines
1925 Postcard of Future New York
Tesla was incredibly optimistic about the future of flying machines from the perspective of 1926.
Perhaps the most valuable application of wireless energy will be the propulsion of flying machines, which will carry no fuel and will be free from any limitations of the present airplanes and dirigibles. We shall ride from New York to Europe in a few hours. International boundaries will be largely obliterated and a great step will be made toward the unification and harmonious existence of the various races inhabiting the globe. Wireless will not only make possible the supply of energy to region, however inaccessible, but it will be effective politically by harmonizing international interests; it will create understanding instead of differences.
The idea of zipping from New York to London in just a few hours would remain a fantasy until the jet age, but we're still waiting on airplanes that "carry no fuel," as he predicted.
Tesla on wireless power and printing newspapers in the home
April 1934 cover of Radio Craft magazine
Tesla was way ahead of his time in so many ways. And since he and Hugo Gernsback were friends, one can draw a direct line between some of the ideas that Tesla had and the fascinating predictions that would show up in Gernsback's many tech and sci-fi magazines. One perfect example is that of the wireless newspaper:
Present wireless receiving apparatus will be scrapped for much simpler machines; static and all forms of interference will be eliminated, so that innumerable transmitters and receivers may be operated without interference. It is more than probable that the household's daily newspaper will be printed 'wirelessly' in the home during the night. Domestic management—the problems of heat, light and household mechanics—will be freed from all labor through beneficent wireless power.
Tesla was predicting wireless newspapers in the 1920s, but the folks at companies like RCA would actually get test runs of wireless newspaper printing in the home by the 1930s. Aside from being incredibly noisy and slow, the things actually worked.
