We don't have it on Tesla's scale. He wanted to transfer wirelessly enormous amounts of electricity and communication on a global scale. His idea resolved using Earth as part of a powerful type-two oscillator... Basically, his solution would have enabled a cheap and global distribution of electricity and communication. "Using a global array of these magnifying transmitters, it was Tesla's plan to establish what he called the "World System", providing multi-channel global broadcasting, an array of secure wireless telecommunications services, and a long range aid to navigation, including means for the precise synchronization of clocks. In a more highly developed state he envisioned the World System would expand to include the wireless industrial transmission of electric power." from http://en.wikipedia.org/wiki/Wardenclyffe_tower http://en.wikipedia.org/wiki/Wardenclyffe_tower - his unfinished project intended for commercial trans-Atlantic wireless telephony, broadcasting, and to demonstrate the transmission of power without interconnecting wires. I don't really think we can imagine what world Tesla saw or what solution he had in mind, but it's clear for us now that Tesla was correct in many of his assumptions regarding the Wardenclyffe tower, e.g.: "Despite the ridicule he has been subjected to by scientists for many years, many of Tesla's ideas are being demonstrated to be essentially correct. For example he correctly predicted the existence of the ionosphere and electrical resonance of the Earth-atmosphere system. Resonance of the earth-ionosphere cavity with a fundamental frequency in the vicinity of 7.3 Hz was demonstrated in the 1950s as the Schumann resonance[37]. The latter phenomenon was named after Schumann, for although Tesla had detected a resonance of the Earth-atmosphere system, he was not taken seriously in his time.[38] Furthermore, Tesla appears to have excited a different terrestrial resonance mode with a fundamental frequency of 11.78 Hz."
