Nikola Tesla's Wireless going Mainstream

The Economist reports about the 'progress' in wireless technology - 100 years after Tesla did it. A nice article about the current state of research into wireless transmission of electricity. It also describes the harvesting of radio frequency electricity (e-smog) in the scale of milliamps to use as new source of power to charge or operate electronic devices, a technique also known as “energy scavenging”. What presumably escaped the author's attention is the fact that Nikola Tesla utilized resonance phenomena of the earth itself to conduct energy. He was not into "beaming gigawatts of power" through the air. Tesla's experiment were high voltage, high frequency, but not necessarily high current. The Wardenclyffe Tower was designed to use the earth as one conductor and to establish the return path by what Tesla called “electrostatic induction” through the air.
"You see the underground work is one of the most expensive parts of the tower. In this system that I have invented it is necessary for the machine to get a grip of the Earth, otherwise it cannot shake the Earth. It has to have a grip on the Earth so that the whole of this globe can quiver, and to do that it is necessary to carry out a very expensive construction."
