12. All for electricity

? Sir? Said Captain Nemo, showing me the instru-ments on the walls of
Here ?, his cabin equipment required for navigation Nautilus. As in
the classroom, I have here under my eyes, telling me my situation and my exact address
middle of the ocean. Al-UNPACKING of them are known as the thermometer marking the
temperature inside the Nautilus, the barometer, which weighs the air and predicts changes
time; the higróme-tro recording the dryness of the atmosphere; the storm? glass,
whose mixture decomposes, announces the in-eminence of storms; the compass,
directs my path; sextant, that the height of the sun tells me my latitude, timers,
that allow me to calculate my length and finally, my glasses day and night to me
They serve to scrutinize all around the horizon when the Nautilus rises to the
surface waters.
? They are the standard tools of the navigator and its use is known me? I answered ?. But
There are others here that respon-den certainly the particular requirements of the Nautilus. That
Quadrant I see, tour a stationary needle is not a gauge?
? It is a gauge, indeed. Placed in communication with the water, the external pressure
suggests, also it gives the pro-depth to which my unit remains.
'And these probes, a new class?
? Son temperature sensor indicating a tempera-ture of the different layers
water.
? I do not know what the use of these other instruments.
? Professor Lord, here I am compelled to give some former complications. I beg
listen.
Captain Nemo was silent for some urge-tes and then said:
Is there a powerful, obedient, fast, easy agent, which folds to all uses and
Queen aboard my boat as master. Everything is done here for his mediation. Me
enlightens, warms my soul and my MECA-mechanics devices. That agent is electricity.
? The electricity! ? I cried quite surprised.
? Yes sir.
? But Captain, the extreme rapidity of movi-ledge that you have not
consistent with the power of electricity. So far the dynamic power
electri-ity has been very restricted and could not produce more pro-very
small forces.
? Lord teacher, my electricity is not around the mun-do, plaster is all I can
tell.
? Well, I do not insist, even if I was amazed that result. One question, however,
I can not answer if you consider intrusive. I think that the elements
You used to produce this marvelous agent must be spent soon. For example, the
Zinc how replaces us-ted, since not maintain any communication with tie-rra?
? I will answer your question. I will say that in the seabed zinc mines exist,
iron, silver and gold, whose exploitation would certainly possible. But I do not turn to
none of these terrestrial metals, but I get the same media sea
produce my electricity.
? From the sea?
Yes, professor, and not lacking the means to do so. I could get electricity
establishing a circuit-tre wire immersed at different depths through the
different temperatures of the same, but I prefer em-plear a more practical system.
? What?
? You perfectly know the composition of seawater. Are each thousand grams
ninety-six hundredths and half water, and two thirds two hundredths
rough-mind / sodium chloride and very small amounts of magnesium and dor-ros
potassium, magnesium bromide, magnesium st4fato and of calcium carbonate. Of that
note-ble cahtldad sodium chloride water contained by mari-na I draw I sodium
necessary to compose my ele-ments.
? Sodium?
? Indeed. Mixed with mercury forms an amalgam-ma replacing zinc in
Bunsen elements. The mercu-rio never spent. Only the sodium is consumed, and the sea I
so abundantly supplied. I must also tell you that the batteries sodium must be
considered the most Ener-cal and its electromotive force is twice that of the
the pi-zinc.
? I understand well, captain, sodium excellence in the conditions in which you are located.
The sea contains. Well. But you have to make it, remove it. How does he do it?
Clear-mind, batteries can be used for such extraction, but if not mistaken,
sodium intake needed by electrical devices would exceed the amount
produci-da. And you happen to consume to produce more than you would get.
? That's the reason why not extract from the batteries, professor. Simply,
I use heat-rrestre coal.
-¿Terrestre?
? Say sea coal, if you prefer? Ca-whistle replied Nemo.
? Perhaps you can you exploit offshore deposits of coal?
? This is and will be to see you. I do not ask more than a little patience, since it has
you time to be patient. Remember one thing: I owe everything to Océa-no. He
produces electricity, andthe electricity gives the Nautilus heat, light, movement,
a word, life.
? But not the air you breathe ...
? Oh !, I could make the air we consume, but it would be useless because when I want to upload
to the surface of the sea. If electricity does not provide me breathing air, other drives, to
less powerful pumps that store it in special tanks, which I
can extend for as long as desired, if necessary, my stay in the ca-pas
deep.
? Captain, I have no choice but to admire. He finds-do you obviously what
men certainly someday discover the real dynamic power
electricity.
? I do not know if they discover? Coldly he replied Nemo capi-tan ?. be that as it may,
You already know the first appli-cation I have made this precious agent. It is he who
It enlightens us with equality and continuity that has no sunlight. Look at that clock,
It is electric and powered by a re-regularity that defies the best chronometers.
I have divided into twenty-four hours, like the Italian clocks, because for me there is not
night or day, no sun or moon, but only this artificial light that led to the bottom of
the seas. Look, right now it's ten in the morning.
? Indeed.
? Here's another application of electricity, in that cua-quadrant used to indicate the
Nautilus speed. An electric wire puts it in communication with the helix
co-slide, needle and tells me the actual running of the ship. Fix-it, right now
We sail at a speed moderate-da, fifteen miles per hour.
? It's wonderful, and I see, Captain, you have done very well by using this agent
It is intended to replace the wind, water and steam.
? We're not done yet, Mr. Aronnax? Capi-tan said Nemo, rising ?, and if
do you follow me, look-back oars Nautilus.
Indeed, he already knew all the front of the ship sub-marinc-, the exact division,
the ram center forward, was this ?? the dining room, five meters, separated from the
library by a watertight bulkhead, ie, impervious to water; library, five
meters; the great hall of ten meters, separated from the captain's cabin for a second
watertight bulkhead; the captain's cabin, five meters; mine, two and a half meters, and,
Finally, an air reservoir seven and a half meters, which extended to the stem. The
together it gave a total length of thirty-five meters. Watertight bulkheads had
doors that hermetically closed by means of rubber seals, and they
guaranteeing safety on board the Nautilus, in the event that a route is declared
water.
I followed Captain Nemo over runners-mos and reaches the center of the ship. There
there was a kind of well that opened between two watertight bulkheads. An iron ladder,
fi-xed to the wall, leading to its upper end. Captain Nemo asked what was the
Using this scale.
? Drive the boat replied.
? What! Do you have a boat? ? I asked astonished.
? So it is. An excellent boat, light and insumergi-ble that helps us to wander and
for fishing.
? But then, when you want to engage in it you will be forced back to the surface
sea, right?
? No. The boat is attached to the upper hull of the Nautilus, housed in a
cavity disposed therein for receiv-yo stud. Has bridge is absolutely waterproofed
and it is retained by bolts solids. This scale leads to an opening made in the
hull of the Nautilus, which com-unique with a similar one in the side of the boat. For that double
aperture is why I enter into the boat. It closes the Nautilus, I close I
the pot by tor-pressure screws, long bolts and then the pot up with
prodigious speed to the surface of the sea. Then I open the hatch of the bridge,
carefully closed until Enton-ces, put the mast, hoisted sail or oars lame, and
I'm ready to pasearme.
? But how do you back on board?
? I am not the one who returns, Professor Aronnax, but the Nauti-lus.
? At his command?
? That's right, because I joined the Nautilus by a power line, I just issued by it a
telegram.
? Well? I said, I wonder ?, nothing more simple, indeed.
Having passed the stairwell leading to the platform, I saw a cabin
about two meters longi-tude in which Conseil and Ned were still co-miendo
with visible appetite and satisfaction. Open a door and found ourselves in the kitchen, about
three meters in length, located between the large pantries on board. There was the
electricity, stronger and more obedient than the same gas, which made possible the
preparation of the comi-das. The cables coming to the stove to communicate
platinum burners heat distribution and regular man-tainment. Electricity
also heated about apara-tos distillers by evaporation
suppl-they lock excellent drinking water. Near the kitchen there was a bathroom very
well with taps they provided them cold or hot water at will installed.
After cooking the bedroom crew was in one piece five meters
length. But the door is closed Taba and I could not see inside that would have given me a
indication of the number of men required by the Nautilus for management.
In the background there was a cuario watertight bulkhead separating the bedroom from the
machines. A door he opened and I entered there, where Captain Nemo? Engineer
first order, surely? He had installed their apa-times of locomotion. Fourth
Machinery, clearly ilu-mined, rnedía not less than twenty meters. EN-taba
divided into two parts: the first, reserved to the elements producing electricity,
and second, the mechanism) -ransmitían movement to the propeller.
Upon entering, I was struck by the sui generis odor lle-naba the piece. Captain Nemo
He noticed my reaction.
Are they gas emissions produced by the use of sodium. But this is only a
slight drawback. Ade-over, every morning the boat fanning purify
completely.
I examined, with the interest can be assumed, the ma-machinery of the Nautilus.
? You see? I told Captain Nemo ?, elemen-tos use and not Ruhmkorff Bunsen,
that would be powerless. The Bunsen elements are few, but large,
strong, which gives better results as we experi-ence. The electricity produced
It goes back, don-of electromagnets acts on a large-scale sis-theme
particularly of levers and gears that transmit motion to the propeller shaft. This,
with a diameter of six meters and a pitch of seven meters and a half, you can give up to one hundred
twenty revolutions per second.
? With what gets you ...
-a Speed ​​of fifty miles an hour.
Here was a mystery, but did not try to clarify it. How could the electricity act
such potency? What could find its origin that almost limited force? Perhaps in your stress
Excessive obtained by coils of a new type? Or in transmission, a system
-known des [L8] levers could increase to infinity? That was what I could not
explain.
? Captain Nemo, I check the results, without trying to explain them. I have seen the
Nautilus maneuver before the Abra-ham Lincoln and know what to expect on your speed.
But not enough to move. You have to know where you are going. Po-der must go to the right or
left, upwards or downwards ha. How do you do to achieve large
pro-depths in which you must find an increasing resistance, evaluated in hundreds of
atmospheres? How do you su-bir to the ocean surface? And finally, how
you can stay in the place that suits you? Am I indiscreet to ask you
taléslweguntas?
? In any way, Professor? Replied the capi-tan, after a slight hesitation ?,
since this submarine boat you never will. You come to the salon, which is our
True cabinet work, and there will know everything you need to know about the Nautilus.
