The gold leaf. [volume] (Henderson, N.C.) 1881-1911, 1899-03-16
HENDERSON, n c., THURSDAY MARCH 16 1885,

had not been forced into the engine
under pressure, and there was no per-
ceptible heat under the boiler; in
deed, the tube which passed for q
boiler was soon shaggy with white
frost. Yet the little engine stood
there in the middle of the room rum
ming apparently without motive
power. making no noise and giving
out no heat or smoke and producing
no ashes. And that is something
that can be seen nowhere else in the
world-it is a new and almost in
conceivable marvel.
FUEL FOR THE TAKING.
''Air." said Prof. Tripler to Mr..
Baker, lis the cheapest material in
the world. but we have only begun
learning how to use it.. We know a
little about compressed air, but al
most nothing about utilizing the heat
of the air. For centuries men have
been digging their source of heat out
of the earth at enormous expense,
and then wasting 80 per cent. OF it in
burning. Coal is only the suns
energy stored up. What do is to
use the SUMS energy direct.
''It is really one of the simplest
things in the world when you under
stand it. In the case of a steam
engine, you have water and coal.
You must take heat enough out of
the coal and put it into the water to
change the water into a gas-that is
steam. The expansion of this gas
produces power. And the water will
not give off any steam until it has
reached the boiling point of PIP de-
grees Fahrenheit.
.Now, steam bears the same rela-
ton to water that air bears to liquid
air. Air is a liquid at 312 degrees
below zero-a degree OF cold that we
can hardly imagine. If you raise it
above 312 degrees below zero it boils,
just as water boils above PIP degrees.
Now then, we live at a temperature
averaging, say, 20 degrees above
zero. In other words, we are 382
degrees warmer than liquid air, we
are living in burning fiery furnace.
A race of people who could live at
312 degrees below zero would shrivel
up as quickly in this room as we
would if we were shut up in baking
oven. Now, then, you have liquid
air-a liquid at 312 degrees below
zero. You expose it to the heat Of
this furnace in which we live, and it
boils instantly and throws off vapor
which expands and produces power. y
WONDERFUL ENGINE.
There would be no practical ad-
vantage of making liquid air for
running an engine, for under ordinary
circumstances it would be more
economical to use the steam direct
according to the present practice for
the reason that quantity of liquid
air introduced into Mr.. Tripler's
engine produces many times its
equivalent in liquid air.
"There is no perpetual motion
about it. The heat of the atmosphere
is boiling the liquid air in my engine
and producing power just exactly
as the heat of coal boils water
and drives off steam. l simply use
another form of heat. ! get my
power from the heat of the sun; SO
does every other producer of power.
Coal, as l said before, is only form
of the suns energy stored up. The
perpetual motion crank tries to util-
ize the attraction of gravitation, not
the heat of the sun.
:'You will understand this pro-
gressive operation better after show
you exactly my process of making
liquid air. Briefly, the liquefaction
of air is caused by intense cold, not
by compression, although compress
sion is part of the process. After
once having produced this cold, l do
not need so much pressure on the air
which 1 am forcing into the liquefy-
ing machine. Indeed, SO great does
the cold actually become that the
external air rushing in under ordinary
atmospheric pressure to fill the
vacuum caused by liquefaction, itself
becomes liquefied. That is, my
liquefying machine will keep on pro-
ducing as much liquid air as ever,
while it takes very much less liquid
air to keep the compressor engine
going. This difference I save. 1t is
hard to understand just how this
comes about, for you must remember
that we are dealing with intensely
low mperatures-an unfamiliar
domain, the influences and effects of
which are not yet we'll understood
and not with pressures.
TEN GALLONS MADE WITH THREE.
I have actually made about ten
gallons Of liquid air in my liquefier by
the use of about three gallons in my
engine. There is, therefore, sur
plusagc of seven gallons that has cost
me nothing and which can use else
where as power"
If Mr.. Tripler can build success
full ''surplusage machine" it is be-
wildering to dream of the possibili-
ties of source of power that costs
nothing.
