Tesla himself said that he did his utmost to *suppress* normal radio transmission, as he considered this to be wasted energy. The Colorado transmitter was in fact nothing more than a huge spherical capacitor with a coil attached. It sat on a tower to prevent arcing with the ground. The other end of the coil was grounded. This "unit" formed one end of a tuned resonant connection that ran through the ground (not the air), and was connected to any other similarly tuned resonance at any distance. The ground (not the Earth's ionosphere - Earth cavity) was the energy transmission medium. It was a one "wire" transmission system, with tuned circuits at both ends. Because it relied on conduction through a real solid conductor it was nearly loss free over large distances (just as the wires we currently use). BTW I am probably the only person on the planet who believes this. :) Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
