Nikola Tesla Books
⢠(-//!!) - 5 This photograph shows one of the very early Tesla coils. The more sophisticated versions developed later at this Colorado Springs site were housed in large buildings with a 4 foot diameter copper sphere elevated some 150 feet above the ground. A wireless transmitting tower built on Long Island, New York, was a sturdy structure 350 feet high. These are now all housed at the Nikola Tesla Musuem on Proletarian Brigade Street in Belgrade, Yugoslavia. In one of his papers he wrote:- "Impossible as it seemed, this planet despite its vast extent, behaves like a conductor of limited dimensions. The tremendous significance of this fact in the transmission of energy in my system had already become quite clear to me, Not only was it possible to send telegraphic messages to any distance without wires, as I recognized long ago, but also to impress on the entire globe the faint modulation of the human voice. Far more significant is the ability to transmit power in unlimited amounts to almost any terrestial distance without loss." It was to prove this point that Tesla lit a bank of two hundred carbon filament lamps consuming about 10 kilowatts, 26 miles from the experimental station without any physical connection between them something that has never since been repeated.
