NEW BALLOON IDEAS.
TWIN SYSTEM SCHEME 70 MAKE
LONG VOYAGES FEASIBLE.

"h'
In Tandem-Hoe Air to Raise and Lower
the Outfit and Titus Keep Hydrogen In
tact For Carrying Purposes.
NJ Savine, a Russian living in Paris,
who is at once "a scientist and a maker
of pictures for illustrated newspapers,
has invented a balloon Of novel design
with which he hopes to accomplish some
remarkable things, the first of which is
a voyage from New York to Europe,
and the second-starting with the warm
weather next year-a journey to the
pole. To arrange for the first mentioned
voyage an agent has been appointed in
NJ. Kroll of New York city.
So far as lifting power is concerned
there is nothing novel in NJ. Savine's
invention. He utilities the hydrogen gas
bag commonly in use among b~alloonists,
with the usual basket below it. This
gas bag is Of 3, 1000 cubic meters capaci-
ty, and the basket will hold two men.
No ballast of any kind is carried in this
basket, save such supplies of food and
drink as would be needed in long voy-
ages. 1t is in the substitute for ballast
that NJ. Savine has developed a novelty.
At the end Of a cable, 40 meters long,
hanging below the basket, is suspended
a second balloon Of 1000 cubic meters
capacity, with a stout metal car at
tached that will carry two men, 800 Kill
ograms Of petroleum, and an apparatus
for burning the oil, and by it's combus-
tion to heat air for initiating this lower
balloon.
The operation of tho whole outfit, as
described by NJ. Knoll, is easily under
stood. On initiating the upper gas bag
with hydrogen the lifting power OBJ
tanned will be sufficient to carry up the
entire outfit to a moderate height-pos-
sibly high enough to reach a steady
current Of air flowing in the direction
in which it is desired to travel.
In this case it will be necessary, ac-
cording to M. Knoll, merely to let the
balloon travel. In case, however, the
hydrogen balloon does not raise the out
fit to the desired altitude, the crew of
the lower balloon will fire up their ap-
paratus and initiate the lower balloon.
Naturally this will gradually relieve the
upper balloon Of the weight suspended
below it, and so the whole concern will
continue to rise until the sought for cur
rent is reached. Then the fire in tho
lower balloon will be turned down, or
entirely off, as may be needed to hold
the balloon at its proper altitude.
Eventually, Of course, the hot air will
cool of a bit and the upper balloon will
be unable to maintain the altitude.
Then, too, the favoring current Of air
may cease to flow or may change its
course. In such cases as these it will be
necessary to again fire up the apparatus
for initiating the hot air balloon and so
keep the balloons in the old current or
lift them to q higher level in search of a
new current. In case they get too high
weight a easily be added to the load
on the upper balloon by debating the
lower one, and so the hydrogen gas can
be kept intact and the balloons be sunk
or raised. as the balloonists may choose.
NJ. Kroll's description of the appara
for heating the air was not detailed,
but he said in general that the petrole-
UNI would be carried in rubber bags and
fed by pipes to a system Of 400 burners
or jets, set like gas burners in a Yankee
butter cake baker, the flames being six
centimeters long and the area of the ar
of burners one square meter
Above this heating surface a metal cone
would capture the hot air and conduct
into the bag above. The system pro-
vides for carrying 500 Kilograms Of De-
troleum, and it is calculated that this
would entirely fill the lower bag go
times. NJ. Savine thinks this will be
ample for all alterations in ballast dur
ing the time needed for aver a voyage
to the pole and back. M. Knoll says
that experiments have been made with
air heater in the presence of many
balloon experts in Paris, and that 81
minutes was the average time required
70 fill the bag holding 1000 cubic me
ters.
The date for starting for the pole il
axed for a day next June, and the start
ing point is to be Spitzbergen island
The time for sailing from New York for
Paris will be fixed whenever any New
York capitalist is sufficiently interested
in such doings to contribute a matter of
b, 900 or $lO,O 900 for preliminary ex-
Denses. New York Sun.
