ARTIFICIAL LIGHTNING erupts from a Tesla coil in the inventor's experimental station in Colorado Springs in 1899 or 1900 [top]. Tesla often employed large wire coils, some wound on a frame running around the lab, to achieve these spectacular effects. In the image at bottom (taken at his New York City lab in 1898), Tesla watches as powerful electromagnetic fields induce electrical streamers packing nearly half a million volts in the front coil.
