Pure" light
Tesla invented a variety of lamps, not all of which show up in his patents. He lit up solid bodies like

the lost inventions of Nikola Tesla
carbon rods in vacuum bulbs, or in bulbs containing various inert gases at low pressure (rarefied). He
noted that tubes devoid of any electrodes may be used, and there is no difficulty in producing by their
means light to read by. But he noted that the effect is considerably increased by the use of
phosphorescent bodies, such as yttrium, uranium glass, etc. Here Tesla lays the foundation for
fluorescent lighting. Applied to such lamps were currents at potentials ranging from a lower limit of
20,000 volts up to voltages in the millions and vibrations of 15,000 cycles per second and up.
Tesla dreamed of creating what he called pure light or cold light by generating electric vibrations at
frequencies that equaled those of visible light itself. Light produced by this direct and efficient means
would require vibrations of 350 to 750 billion cycles, but Tesla believed such oscillations, far above
those attainable by his coils, would someday be achieved. Even so, his rarefied gas-tube lamps
produced a light that more closely approximated natural daylight than any other artificial source Tesla's
light is like the full-spectrum light that is coming to be recognized as far more healthful than Edison
incandescent and particularly more healthful than conventional fluorescent. Full-spectrum lighting is
believed by some health practitioners actually to have healing properties.
No sudden burnout
Tesla's gas tube lamps burn indefinitely, as do today's neon tubes, for there is nothing within to be
consumed. Tesla's lamps that contain electrodes like carbon rods, however, do undergo some
deterioration. In Tesla's words, a very slow destruction and gradual diminution in size always occurs,
as in incandescent filaments; but there is no possibility of sudden and premature disabling which
occurs in the latter by the breaking of the filament, especially when incandescent bodies are in the
shape of blocks. In vacuum lamps, the life of the bulb depends upon the degree of exhaustion, which
can never be made perfect. Also, the higher the frequency applied to such a lamp the slower the
deterioration. Electrodes glow at high temperatures, and this raises the problem of how to conduct
energy to them since wires or other metallic elements will melt. The problem must be addressed in
lamp design. For example, in the incandescent lamp shown at the opening of this chapter, the lead-in
wires connect to the hot electrodes via bronze powder contained in a refractory cup. Tesla may have
designed his capacitor-base bulbs to help address this same problem.
High heat
Tesla's search for the ideal electrode is reminiscent of Edison's search for the long lasting filament:
The production of a small electrode capable of withstanding enormous temperatures, said Tesla, ìI
regard as the greatest importance in the manufacture of light. One of the electrodes he tried was a
small button of carbon, which he placed in a near vacuum. Tesla regarded the high incandescence of
the button to be a necessary evil. For lighting purposes, it was the incandescence of the gas remaining
in the mostly evacuated chamber that was important. But the carbon-button lamp proved to have some
remarkable properties beyond its use for illumination. When the voltage was turned up, the lamp
produced such tremendous heat that the carbon button rapidly vaporized. Tesla experimented
extensively with this fascinating phenomenon. For the button of carbon he substituted zirconium, the
most refractory substance available at the time. It fused instantly. Even rubies vaporized. Diamonds,
and, to a greater degree, carborundum, endured the best, but these could also be vaporized at high
potentials.

the lost inventions of Nikola Tesla
Tesla worked on the problem of heating. I have read that he contributed to the development of a highfrequency
induction heating. Did Tesla work on the problem of space heating? Certainly the huge
current draw of conventional electric heaters, which use resistive elements, argues for some
inventiveness in this area. Tesla did observe that the discharges from a tesla coil resembled flames
escaping under pressure and were indeed hot. He reflected that a similar process must take place in
the ordinary flame, that this might be an electric phenomenon. He said that electric discharges might
be a possible way of producing by other than chemical means a veritable flame which would give light
and heat without material consumed. The behavior of the carbon-button lamp suggests that a new
heating mode might be found in the effects of high-frequency currents in a vacuum.
Lighting up the sky
Hold a fluorescent tube near a Tesla coil and it will light up in your hand. This is true of any tube or
bulb with vacuum or rarefied gas. A more efficient way is to ground one end of the tube and put a
length of wire as a sort of antenna on the other. Better yet, put a coil of wire that resonates with the
secondary in series with the tube and ground and you have the optimal wireless power arrangement.
Tesla conducted many experiments with different arrangements like this, using on some occasions the
widely available Edison filament incandescent, which lighted up more brilliantly than usual because of
the effects of high frequencies on the bulbs rarefied interior. Inside his New York lab Tesla strung a
wire connected to a tesla coil around the perimeter of the room. Wherever he needed light he hung a
gas tube in the vicinity of this high frequency conductor.
Tesla had a bold fantasy whereby he would use the principle of rarefied gas luminescence to light up
the sky at night. High frequency electric energy would be transmitted, perhaps by an ionizing beam of
ultraviolet radiation, into the upper atmosphere, where gases are at relatively low pressure, so that this
layer would behave like a luminous tube. Sky lighting, he said, would reduce the need for street
lighting, and facilitate the movement of ocean going vessels. The aurora borealis is an electrical
phenomenon that works on this principle, the effects of cosmic eruptions such as those from the sun
being the source of electric stimulation. I, for one, am grateful that this particular Tesla fantasy never
materialized since it is difficult enough to see the stars with existing light pollution, and there might be
undesirable biological impacts as well.
Rotating brush
Tesla took an evacuated incandescent type lamp globe, suspended within it at dead center a
conductive element, stimulated that element with high voltage currents from an induction coil, and thus
created a beam-like emanation, a brush discharge that was so eerily sensitive to disturbances in its
environs that it seemed to be endowed with an intelligent life of its own. The device works best if there
is no lead-in wire. In the bulb shown, every measure has been taken to construct it so it is free from its
own electrical influence. The bulb could be stimulated inductively by applying energy to metal foil
wrapped around its neck. Thus excited, an intense phosphorescence then spreads at first over the
globe, but soon gives place to a white misty light, observes Tesla. The glow then resolves into a
directional brush or beam that will spin around the central element. So responsive is it to any
electrostatic or magnetic changes in its vicinity that the approach of an observer at a few paces from

the bulb will cause the brush to fly to the opposite side. A small, inch-wide permanent magnet will
affect it visibly at a distance of two meters, slowing down or accelerating the rotation according to how
it is held relatively to the brush.
