DEFINITION OF A DARKBULB

Edited by Dr. George H. Scherr,  Workman Publishing, New York

James L. DeLucas

The darkbulb is an electronic device thai produces darkness. It is
similar in appearance to the ordinary lightbulb. Whereas the lightbulb
is considered an energy source, the darkbulb could be considered an
energy sink.

The darkbulb looks like the ordinary lightbulb. It is much heavier, a
typical 60 watt bulb weighing about two pounds. The darkbulb's outer
shell is made of a special metallic material called heliotex. Heliotex
was made specially for the bulb, and it is necessary for the bulb's
operation. The bulb screws into an ordinary light socket and can be
run on house current. The bulbs are normally coated black for easy
identification.  Darkbulbs come in power sizes similar to the
lightbulb.  Two and three-way bulbs and special purpose bulbs are also
available.

The Hay Field

Unlike the simple heating filament of the lightbulb, the inner
contents of the darkbulb are complicated and electronic. The heart of
this device is the crystalkanoogin valve. The crystalkanoogin valve
was designed by Edison A. Thomas, an engineer at General Electric.
(See "An Inexpensive Dissipator of Radiant Energy," Electronics,
Vol. 42, No. 7, pp. 59-67, July 1970.) The valve is made up of a
series of miniature electronic components. The sole purpose of the
valve is the production of the Hay field.

The Hay Reverse Electromagnetic Field, or Hay (REF), was theoretically
proven to exist by R.E.F. Hay at MIT in late 1969. This invisible
field is able to dissipate normal electromagnetic energy, such as
light, by converting this energy into the reverse electromagnetic
energy of the Hay field. This energy conversion process is the means
by which the Hay field propagates through the air. In a vacuum the Hay
field would propagate indefinitely. In air, however, the Hay field
would lose energy to the surrounding medium and it would soon
disappear.  Thus, the crystalkanoogin valve must continuously produce
the Hay field. Also, the Hay field will not propagate unless the
surrounding medium contains electromagnetic energy, since the Hay
field uses this energy to sustain itself.

The Hay field is analogous to a vacuum cleaner that sucks
electromagnetic energy from the air.  Electromagnetic energy such as
light can be thought of as being absorbed by the darkbulb and then
converted into the Hay field. The recycling of the trapped light
energy not only solves the energy dissipation problem but also puts
this energy to useful work.

The crystalkanoogin valve sets up the Hay field on the inside surface
of the heliotex shell. The properties of the heliotex material cause
it to radiate the Hay field into the surrounding space, much like a
lightbulb would radiate light energy from the heating filament.  The
heliotex shell thus acts as a radiating antenna for the Hay field. The
type of radiation absorbed by the bulb is dependent on the impurities
present in the heliotex shell. The impurities can be controlled during
the making of the heliotex. Thus, special purpose bulbs that absorb
only one kind of electromagnetic energy can be made. For instance, it
is possible to Create a darkbulb that absorbs only red light, or a
bulb that absorbs only cosmic rays.

During operation, the surface of the bulb will actually become cool
due to dissipation of heat from the heliotex material. The darkbulb
"sucks" light energy from the air, but the bulb is not a perfect
discriminator, and very small amounts of other forms of energy in the
vicinity of the bulb will also be dissipated. The bulb will become
cold because of a loss of heat energy to the field.

The ordinary darkbulb is one that will absorb light. The bulb will
dissipate light, that is, produce darkness in as large an area and to
as comparable a degree as a lightbulb of the same wattage will produce
light.

The Dark Fantastic

The ordinary darkbulb has many uses. A flip of the switch makes it
possible to sleep in the daytime 

     [ Image not available]
     Sunlight streaming into a room inhibits sleep, but flipping on
     the darkbulb envelops the subject in soothing darkness.

     [Image not available]
     Darkbulbs come in a variety of sizes, shapes, and wattages.

without the use of eyepatches. Photographic enthusiasts no longer need
to spend money "lightproofing" a darkroom. Just screw a darkbulb into
a socket and any room becomes an instant darkroom. Eye doctors have
found darkbulbs particularly useful for conducting eye
examinations. There are applications of the bulb in the scientific
fields, where many experiments require the absence of surrounding
radiant energy. The darkbulb also seems to be popular at parties.

Special purpose darkbulbs are finding wider applications. The special
purpose radio wave darkbulb will absorb radio waves from the
surrounding area. One application of this bulb is in the scientific
field where certain experiments require shielding from radio
waves. The cosmic and X-ray darkbulbs absorb cosmic energy and X-rays
from the air. These potentially hazardous forms of energy can now be
snatched from the air before they reach the vulnerable human being.
As scientific technology advances, the special purpose infrared
darkbulb will eventually be produced.  Such a bulb would absorb
infrared (heat) energy. The invention of this type of darkbulb would
have a profound effect on modern society.

Refrigerators would no longer need a complex mechanical cooling
system -- just an infrared darkbulb inside. Sunbathers in the
vicinity of an infrared darkbulb could get a tan without worrying
about the harmful rays that cause sunburn.  Air cooling could be
accomplished with a darkbulb.  Unfortunately, technology has not found
a way to prevent the heliotex shell from becoming frozen solid during
the bulb's operation. In the frozen condition, the heliotex shell
fails to maintain the Hay field.  

The darkbulb can be found in any store that carries lightbulbs. The
cost of this modern advance in technology has been considerably
reduced, although it is still much more expensive than the
lightbulb. However, the darkbulb is not beyond the reach of the
average-income American family. Indeed, they are becoming as common as
the home radio.

But surely someone has put a blacklight in a computer case:

All that paint is going to make a mess.

You can get an RGB keyboard (like mine), an RGB wrist pad for the
keyboard, an RGB mouse, an RGB pad for under the mouse, RGB speakers.

It can be quite a light show.
My office has XMAS lights running around the ceiling, one
desk lamp, and the glowing keyboard.  Oh, yeah, forgot the glowing
speakers (not RGB, just color changing lights).

I'm sort of maxed out on glowing lights.

Because it's built around light _emitting_ diodes, it is necessary to use
additive color mixing instead of subtractive color mixing. Now if you
instead used a white backlight, behind a three-layer liquid crystal panel
with a suitable design...

I was joking, of course ... but I /did/ find "RGB" a strange name for
the feature "can emit any color". OTOH I cannot easily come up with a
better one ... possibly "controllable colored light".

Brown = #A52A2A

Looking at the color it's pretty much what I'd expect brown to be.
Perhaps "saddlebrown" is a little closer.

SaddleBrown=#8B4513

So, high on red, low on green and blue.

I think I know where you're going with this, but I did shine it on
something.  I started an xterm with:

xterm -bg brown
then
xterm -bg saddlebrown

In both cases I see light on my screen that looks brown.
Doesn't that count as "shining"?

Well, it's 'through', rather than 'onto'

Well, there's probably an "onto" in there somewhere.

I don't understand what you are trying to say here.  Fill the OLED
screen on my phone with brown, and point it at something in the dark,
the something appears brown.

The Amiga computer had a RGB monitor, red-green-blue.

I meant to say it looked strange /in context/: I googled and found web
pages about "RGB computer cases".

I had never heard about this phenomenon before. I have obviously not
been paying attention. I went to a local store's page now, and decided
to look at desktop (non-tower) cases.  The only hit was for a case
that was built into an actual desktop!  (Lian Li DK-05F).

I also note that 241 cases out of 309 there were black, the most
impractical color for a piece of hardware.

Oh, come on. When I was a kid and interested in electronics (not 
exactly pre-computer, but before transistors were common), me and my 
friends knew that the way to identify the best (often surplus) 
equipment was that it had a black crackle finish. But even today, the 
3 towers in eyeshot of my desk have black cases. (Crackle, alas, seems 
to have vanished, probably takes too long for the paint to set. Or 
it's just out of fashion.) What's impractical?

Hard to see the connectors and switches without a strong light.

It's worse with keyboards, though.  I have an Apple Aluminium these
days, with white keys.  A wonderful keyboard in every way (except for
non-standard keycodes -> extra configuration needed).
