Experiments with Alternate Currents of High Potential and High Frequency (1892)
Nikola Tesla - Experiments with Alternate Currents of High Potential and High Frequency
There is no doubt that with the enormous potentials obtainable by the Use of high frequencies and oil insulation luminous discharges might be passed through many miles of rarefied air, and that, by thus directing the energy of many hundreds or thousands of horse-power, motors or lamps might be operated at considerable distances from stationary sources. It is now a fact that a body may be rendered incandescent or phosphorescent b) bringing it either in single contact or merely in the vicinity of a source of electric impulses of the proper character, and that in this manner a quantity of light sufficient to afford a practical illuminant may be produced. It appeared that under the molecular impact caused by the rapidly alternating potential the body was fused and maintained in that state at a lower temperature in a highly exhausted bulb than was the case at normal pressure and application of heat in the ordinary way -- that is, at least, judging from the quantity of the light emitted.
