patent process now that viii really start
the air moving The theory OF all cooling
apparatus Is to start the air circulating
In breeze is GOODNESS. To make whole
town breezy on a hundred-in-the-shade
day is equivalent 10 lowering the temper
azure p degrees, though the actual tenn
perature by thermometer remains the
same. A few machines aim to cool the
air at the same time while moving it, but
most OF them only agitate It.
The new device which aims al giving
cool weather In dog days requires consld-
cradle apparatus 1t needs tall sfruc-
lures like windmills, and many Of them
These must be connected with the ground
by wires, and with each other also, by
Joining wire on top OF the tower is not
absolutely necessary.
The aim Of this machine is to send large
bombs up these wires from the ground TO
the top of the windmill structure. When
they reach the top. or get well of from
the ground, they explode. That brings
GOODNESS.
The windmill structures are erected
in this shape for beauty The picturesque
element OF the cross arms, the little struc-
ture and their grace are the reasons this
form is selected. It's economy is another.
A framework OF wood is cheaper than a
tower of wood. And Of course cheaper
than stone. To make these windmills still
pretter, there are vines planted around
lHEm, ana the windmill and It's arms can
be covered with verdure in summer when
they are In operation In winter they can
be taken down and stored away until next
season.
The important element Of the windmill
cooling apparatus is the bomb This is an
immense affair filed with carhonic acid
gas in a hQuefed state. The gas is pat
under powerful pressure until it lique-
shape.
The machinery of the cooling apparatus
consists of electric wires besides the car
bonic acid bombs. These wires are run
by power, so that they carry the bombs
along quickly to the top Of the tower.
Once there they come under powerful
electric shock and are exploded
Carbonic acid gas is much heavier than
the surrounding atmos phere. Primarily
II is the substance that is breathed off
from the lungs, and it settles low in cell
lars, underground and near the surface
of the earth. 1t is not a good substance
to work with in this state. But the fact
that II is heavier than common air and
settles low IS the principle upon which
the explosive works.
As soon as relieved of the pressure af-
ter the explosion of the bomb. the liaue-
ned acid eVaporates and becomes gas
again. In this evaporation the atmos-
phere around is severely chilled and the
carbonic acid gas, rushing downward
produces a swift current Of cool air. The
air upon the ground must rise as the cold
air PUSHES down. This makes a wind
equal TO the strongest northwestern
That in simple language, is what hap
pens. In its operation it requires power
ful machinery for pressure and delicate
electric apparatus.
The scheme of carrying it out is pro-
posed for whole cities. A string of tow
efs or windmills with wires attached to
them, would have to be built around the
town and the bombs operated from them
on a hot day. It's expense is considerable
and so II is likely that none but model
towns VIII try 1t right away. For a place
