One of the greatest phenomenon produced by Tesla
apparatus is the Flaming White Arc. This intense, highly efficient flame is produced by a finely tuned combination of transformer containing a low potential secondary, a mica condenser, and a highly quenched spark gap, and a Multilayer Disruptive Discharge Coil wound in Pancake form. The prototypes above used from 2 1/2" - 4" diameter coils. Seen above is the earliest prototype that I created on 14. September 2001. The transformer used in the above prototypes is a small microwave oven transformer, delivering around 2000V. This transformer was used to charge a mica condenser of .014 mfd. It was vital that the condenser be made of mica and copper foil - the temperature of this condenser during operation reached several hundred degrees! The spark gap was a special quenched gap used originally in a 1930s Fischer Diathermy Machine. It was a 5-series spark gap made of self-cooling aluminum heat sinks, faced with massive 3/4" diameter tungsten discharging points. The length of each gap was adjusted from .001 - .003", depending on desired effects. When the switch was closed, and the 1/8" diameter tungsten discharging rods were about 4" apart a massive violet arc jumped between the rods, interposed with this arc were occasional orange flames - the output was similar to that of a larger High Frequency X-Ray Coil. When the dischargers were moved closer together, approximately 2" apart, the violet - orange arc turned into a blinding white arc, the heat of which could be felt several feet away. This arc was as bright as a welding arc, and was hot enough to actually disintegrate the 1/8" tungsten rods - indicating temperatures in excess of 6000 degrees! I could temporarily take this discharge to my body with a large piece of metal held in my hand, however the heat felt within my arm indicated massive effects of Diathermy - which could have led to the actual cooking of the internal tissues, had I not have halted this rather dangerous experiment! It was vital to note that the discharge was that of pure high frequency currents, no faradic sensation or low frequency currents were felt at all. (I mention this in response to several skeptics that arrogantly posted remarks that these photos must have been low frequency arcs!) In replacing the tungsten dischargers with copper, steel, or brass rod all materials would melt within seconds from the intense heat. Documents of this phenomenon can be found in the Thomas Stanley Curtis masterpiece High Frequency Apparatus. |

The third prototype was demonstrated by Bill Wysock of
Tesla Technology Research at the 2001 AMTA Convention in Denver, Colorado. |
