The Hawaiian star. [volume] (Honolulu [Oahu]) 1893-1912, 1912-04-13

The supreme marvel in optics has
come to pass A substitute for day
light has been invented.
Now if you want to turn night into .
day you can buy the daylight to do
it.
For the way to make daylight has
been discovered and the materials Of
which it is made 1t has taken twenty .
centuries to find it out, and about |
fifteen years of experiment to bring
daylight to market so the world could
buy. But this very new discovery is
now a commercial fact, already with
millions in it,
Daylight is actually manufactured
by New York company with head
quarters on Fifth avenue, a window
less office flooded with the bright light
Of noontide continually by this COM
mercial duplicate of sunlight The
United States Bureau of Standards at
Washington has proclaimed the new
light the only artificial illuminant re-
producing daylight
Before the lay public even heard OF
the invention, the textile mills, dye
houses, oil refneries and lithograph-
ing plants snapped it up eagerly as the
one thing in the world to make them
independent of the time of day and
the weather in the hours of their
work
The day he's never been long enough
Tor some folk, and the way the solar
supply was distributed has never suit
ed others. But so long as Old Sol and
his lighting system has control OF
the situation, some 93,i00,O0O miles
outside the jurisdiction of all Leg.sla
lures and public-service boards, moth,
ing was to be done about it.
But now. behold, daylight is a do
mestic product
If the sun gives out, why, here's
recipe for daylight:
Put a little carbon dioX.de gas in
vacuum tube and run an alternating
electric current through it-and then
the result is daylight!
You can carry $50 volts of it around
is a suit case.
You can install it in daylight room
in your home or shop or office, and the
daylight VIII shine a year without re
newing the window" Or, YOU cal
keep it canned for six months in thu
land of the midnight sun, and it viii
light the other six months for yol
when YOU are ready to trun on thu
current.
It is as portable rs a photograph o
typewriter and who knows, if day
light was generally used for lightini
the night and the darkness instead
gas and electricity, but that this pool
myopic, astigmatic world might She
its eyeglasses and spectacles in on
generation!
II you read this the Sunday morn
ing it IS printed, look out of the vii
dow and conceive the wizardry Of tn
process by which the light of day wa
analyzed that it might be reproduce,
There have been lights and light
that have tried to duplicate daylight
and to realize the real marvel of ma
ing daylight it is necessary to tas
