several ways by which we become
aware of the existence of this pres
sure. 1t exists and acts equally
in every direction, or, in othel
words, it is always tending te
, equalize its effect in all directions.
take pipe, attach an exhaust fan
to one end, exhaust the air (the
medium ON which the pressure
acts) by applying power or mo.
ton to the fan. You remove the
air from the pipe. The tendency
of the universal pressure to estab-
lish an equilibrium forces more air
in at the other end, in an effort to
maintain the pressure of the in
side equal to that of the outside.
Now if you will place any kind of
an air motor, or fan, within the
pipe or in the path of the air as it
is forced in, the motion of the air
will cause your motor to revolve
and give back as mechanical mo-
ton a portion of the energy sup
piled to the exhaust fan. Stop the
exhaust fan; sufficient air will fill
the pipe to equalize the pressure,
and the motor will also stop The
pressure in an equalized or satisf-
ed state will not produce any mo-
ton. 1t requires cause to pro.
duce an effect. The air which
filled the pipe was not the cause
which produced the motion; it was
only the medium on which the
cause (pressure) acted. 1t was the
condition of the air, not the air,
which performed the work. There
was more air in the pipe after the
equilibrium was established than
there was while it was being dis
turbed. but it was not in state of
potential; that is, it did not have,
by its condition, the power to do
work. In the illustration the pri-
mary work was done by driving
the exhaust fan; the transforma-
ton Of that motion was done
through the pressure.
Suppose we take our pipe and
close each end, then divide the
pipe in the middle into tight
chambers. Now the air within
each chamber is at atmospheric
pressure, Is pounds per square
inch. Insert an air pump SO that
q portion of the air may be taken
from one of the chambers and
forced into the other. We will
then have partial vacuum on one
side and an increased pressure on
The other side of our particion,
and each chamber will be in a con-
lition known as a state of poten-
.ial. That is, each chamber now
has within itself the power to per-
;orm the work, which may be
lone when Nature is allowed to
,qualize the pressure within the
;wo chambers with the all prevail
ng pressure within. Should we
connect the two chambers together
~ pipe attached to a suitable
motor, work would be performed
when the air passes from the
'hamber of high pressure to that of
over pressure, and as long as We
work. our pump to increase the
pressure on one side and decrease
t on the other, Natures efforts to
xuaIize the pressure in the two
hambers will continue. We will
all our pump a dynamo. The
wo chambers are the positive and
legatlve side of our dynamo. The
alive of our pump performs that
vhish the magnetism of our dyna-
40 performs; that is, it raises the
'ressure on one side and decreases
on the other. The pipe by
7hich we connect the two cham
'ers together is ovr circuit. To
ssist US in this illustration, we

is In state of potential. The
esilience of the spring will give
