Curioso ver que sucede si escribimos una incoherencia como buscar:

Probemos :-) Pues oq lo ignora y si buscamos solo con oq lo ignora también...
Y lo que he visto es que para abrir directamente la página resultado de imágenes basta con añadir

&tbm=vid
jajajaja que sucede si le pido vídeos e imágenes??!??

Pues al ser la misma variable, como se llama en este contexto, pues vid al ser más reciente en su lectura sobreescribe el contenido de la variable tbm que era imágen y nos muestra solo vídeos de submarinos de los estados unidos de America.
Me acabo de dar cuenta que no son enlaces a vídeos en sí sino a páginas webs que supuestamente contienen dicho vídeo o lo tuvieron...

You can't see her, she can dive to over 250 meters and stay down for six months.
you can't hear, she can run for 20 years without refueling
She is the most lethal weapon ever designed.
An apocalypse machine capable of devastating entire continents
The USS Pennsylvania is an ohio-class submarine, the biggest submarine in the US Navy.
~ Now I'm right 15 degrees rudder steady, course three two zero ~
Captain Bradford S Neff is taking the USS Pennsylvania and its crew of a hundred and sixty-five men on a patrol.
His submariners are a unique breed.
Sailors on my ship have to be able to deal with being inside for an entire patrol which is not only about 72 days or so.
During this time the Pennsylvania will silently glide through the depths of the Pacific Ocean.
Invisible to her enemies, she is primed to unleash her awesome apocalypse in an instant.

Each crewman needs 12 cubic meters of air every day just to stay alive, more if they're working hard.
Even in a vessel as roomy as this, the Pennsylvania's crew would run out of air after just seven days.
so where do they get their air from
the answer the very thing they're traveling in
sea water
by passing electricity through the water it's possible to split the substance into its component parts hydrogen and oxygen
chemist and Rashid Lowe will demonstrate how this works so we have this apparatus set up
here the positive electrode here is giving off oxygen and
the negative electrode here is giving
off hydrogen what I'm going to show you
now is that we can collect the oxygen
and then reignite a glowing splint with
it thus proving that that's the gas so
I'm going to now turn our tap very
carefully here we now have a tube full
of oxygen we're now going to do the
classic test for oxygen gas which is to
see whether it relights a glowing spit
there we go one two three four five a
new world record sixth absolutely Bryn
so there we are oxygen from water by
electrolysis electrolysis is also used
on the Pennsylvania to make oxygen from
seawater but on a much bigger scale here
we have the oxygen generator her
nickname is Paris after the Hilton
sisters number one she's actually Nikki
because we think Nikki's better
no offense Nikki produces over 4,000
liters of oxygen every hour the oxygen
is used to replenish stale air which is
then circulated around the vessel pure
clean air thanks to the Hilton sisters
we need to breathe and if she doesn't
make option for us then we can't breathe
so we like to tend to her keep her happy
over two centuries ago the Turtles
operator could stay submerged for just
25 minutes on the Pennsylvania today the
supply of air is limitless when people
first built submarines I didn't really
know how to control them so they look to
nature for inspiration and they copied
the fins of a fish by putting metal fins
on the side of the submarine the USS
Pennsylvania also has fins called planes
they're operated by two of the youngest
crewmen on the ship this watch station
here is one of the first ones we qualify
your young operators on and some guys as
young as 18 19 years old are actually
driving the submarine through the water
he's got control of these fair water
planes right here they're very good at
depth keeping the operators instructions
are transmitted electronically to the
by adjusting their angle he can move the
submarine up and down in the water
the Pennsylvania has a second set of
planes at the rear outboard controls the
stern planes which you can see with this
gauge right here the stern planes are
all the way in the back of the submarine
much like the elevators on an airplane
they control the ship's angle
we can essentially fly the ship much
like an airplane under the water
during mealtimes we generally go up or
down level deck so we don't send the
food the drinks and everything else
sliding off the tables but if we had to
we'd go up and down and every once in a
while exercise that and they'll play
catch the plate down there
in World War two Hitler's submariners
need a way to attack Allied shipping
from a distance one weapon already
exists that fits the bill a torpedo that
it's powered by a tank of compressed air
and the air is released into two Pistons
their motion drives a propeller which
pushes the torpedo through the water but
this torpedo has a fatal flaw the
compressed air propelling it leaves a
telltale trail of bubbles this makes it
easy to see it coming so the German Navy
designed a torpedo that won't advertise
its position with a wake of bubbles it
doesn't run on compressed air
this new torpedo works off a small
but it needs an enormous battery to
power it to accommodate the battery the
torpedo needs to be over seven meters

line these high-tech robots can be
guided on to their target shut to -

an optic fiber spooling out of the back
of the torpedo carries the weapons
this allows him to steer the torpedo
crops under whole oceans unironically
and verging on the bearing of 0-7
Thunder Khan I now write 15 degrees
rudder steady for 3 to 0 as the torpedo
closes its onboard sensors lock on and
guide it in for the kill during the
second world war the German Navy have to
urgently solve the refueling problem
their u-boats are trying to sever
Britain's supply line of ships from
North America this takes the u-boats a
long way from home and from fuel
what they need is a way to refuel at sea
so the Germans invent a submarine that
carries fuel rather than firepower they
call it the milk cow to build it
engineers take a standard u-boat and fit
extra fuel tanks these hold 400 tons of
fuel to deliver fuel the milk cow must
surface and roll across a fuel line
during the five hours it takes to refuel
neither submarine can dive to safety
which leaves them vulnerable to attack
for the British the milk cows were
clearly a most important target if you
could attack them and sink them that
would then limit the endurance of all
the other German submarines in the
by the end of the war the Allies sink
all 10 of the German milk cows
the lesson is clear refueling a
submarine at sea is too dangerous
Engineers must find a way to make their
the answer comes in 1945 with the dawn
of the Atomic Age American scientists
attempt to harness the colossal energy
released by the splitting of an atom to
power their new submarine they fit it
with a nuclear reactor this breaks down
uranium which triggers a massive release
of heat this heat is used to generate
steam the steam shoots through a series
of turbines forcing their blades to
these then drive the propellers
but the nuclear reactor is enormous and
to accommodate it the new submarine has
to be vast the technical difficulties of
getting a nuclear reactor into the
confines of a submarine hull were just
tremendous no one had ever built a
nuclear reactor of the required type
before no one had ever tried to
deliberately put it inside a submarine
and lower it into the sea no one really
knew just how much power you could get
from a nuclear reactor no one had done
it before American engineers rise to the
challenge and in 1954 unveil the USS
Nautilus the world's first
nuclear-powered submarine
she has no need to be refueled at sea
she can travel an astonishing 100,000
kilometers on just four kilograms of
the impact of the Nautilus the first
nuclear-powered submarine was tremendous
suddenly you had a submarine that could
operate anywhere in the world and get
there by traveling dived all the way
today on the USS Pennsylvania behind
this watertight hatch lies one of the
most highly classified pieces of US
military hardware the submarines nuclear
reactor this reactor is far more
powerful than the prototype that powered
the Nautilus it pumps out more than
enough electricity to propel the 17,000
ton Pennsylvania through the water at 45
kilometers per hour it also runs the
myriad of machines and equipment on
board fueled by a lump of uranium the
size of a fist there's no sign yet of it
needing to come in for a top-up
this submarine was commissioned in 1989
20 years ago has not been refueled yet
the one thing that limits our ability to
so it's fuel for the crew rather than
for the submarine that limits the range

month supply and it's some of the best

they've learnt their lesson from the
Russian submarine Kursk she sinks in
2000 with the loss of all hands

long to control a fire and the submarine
captain Neff allows his crew just six
minutes to bring the simulated fire
under control well within time the fire
marshal sounds the all-clear their
regular practicing has paid off in the
1950s scientists on both sides of the
Iron Curtain raced to build a
and what better way of launching it than
from a submarine the idea of putting
these things on a submarine was quite
simple that the submarines are very
difficult to find and they are therefore
a secure base from which to conduct a
nuclear attack the Russians were the
their missile is so tall the only place
they can squeeze it in is behind the
conning tower to launch it the submarine
must first surface and hoist the missile
above deck but a submarine on the
surface is an easy target for an enemy
the Americans want to take this Soviet
breakthrough a step further and come up
with a submarine that can launch
missiles without having to surface first
the problems facing the Americans were
enormous they were designing a submarine
to launch these missiles from under the
water no one had ever fired a missile
through the water before rocket engines
need air to burn so they won't work
underwater so the engineers consider
using compressed air instead so the
secret is a seal that prevents water
flooding into the launch tube when the
missile hatch opens a moment before
launch the seal is blown apart before
water has a chance to pour in a valve
opens shooting a burst of compressed air
into the bottom of the launch tube the
air forces the missile out of the tube
and over 80 km/h it has enough momentum
to cut through almost 40 meters of water
once in the air its rockets are able to
ignite Man Battle Stations missile she
it's day 15 of the mission and the
captain runs the crew through a
well-rehearsed exercise launching a
nuclear strike the USS Pennsylvania
carries 24 Trident nuclear missiles and
is unconstant readiness to respond to a
message to launch them Kevin we were
receipt of a valid emergency action

package 0-1 request permission to
authenticate authenticate the message
shaky the message I sir Gulf Oscar the
command to launch a nuclear missile is
encoded with a cipher to ensure that the
order has come directly from the

concur I concur authorize the launch
whether it's going here from mr. fire
after missing the fire at Conn weapons
five away these missiles are so big they
need more than compressed air to get
the Pennsylvania uses a small rocket
fired into a tank of water the water
super heats and instantly turns to steam
this column of steam propels the missile
through the water into the air
the nuclear warheads on this submarine
alone are more destructive than all the
bombs dropped in both world wars
in the depths of the ocean light doesn't
penetrate the water more than a few
hundred meters sound waves however can
travel through the water for many
hundreds of kilometers those hunting the
USS Pennsylvania are listening out for
any noise she makes that might give away
her position section brain 379 does need
to be stealthy the Pennsylvania must be
silent one of our primary missions is to
remain at sea undetected and so our job
day-to-day hour-to-hour is to remain
quiet so that no one knows where we are
everything on the submarine the decks
equipment running machines and even the
hand dryers are insulated with rubber
shock absorbers to minimize noise caused
by vibrations the other large source of
noise that can radiate out of the ocean
is our propeller that broadband noise
can travel extreme distances in the
ocean before designers can build a quiet
propeller they have to understand why it
makes so much noise if a propeller spins
quickly it leaves a trail of bubbles
behind it as the bubbles pop they make a
these bubbles are not filled with air
but with steam the steam is produced by
the sea water boiling it is a well-known
fact that water boils at a hundred
degrees centigrade however few people
will know that at different pressures
the water will boil at different
temperatures if you increase the
pressure as in a pressure cooker for
instance then the boiling point of the
hence the cooking is more efficient few
people will know however that at reduced
pressures water will boil at lower
temperatures I have here a vacuum pump
and I'm going to turn on the vacuum this
flask here contains water and we have it
connected to a pressure gauge and we're
reading at the moment approximately 15
pounds per square inch which is one
atmosphere I turn on the pump you notice
the pressure dropping immediately and as
the pressure drops as we approach zero
bubbles start to form and the water
starts to boil so here we are at room
temperature but at a significantly
reduced pressure almost almost the
complete vacuum the water is now boiling
water boiling at twenty degrees
centigrade at almost 0 pounds per square
inch a remarkable phenomenon sad
when a submarines propeller turns
quickly an area of low pressure is
this lowering of pressure causes the
water to boil without heating up and
produces bubbles of steam this is called
formation those bubbles is dependent on
how fast we rotate our propeller so the
faster we go the more risk we are for
cavitation the Pennsylvania's propeller
design is a closely guarded secret but
the basic principles of a quiet running
propeller are known cavitation only
occurs when a propeller spins quickly
slowing the propeller down reduces
cavitation and therefore noise but
slowing the propeller also reduces a
submarines thrust to overcome this
problem the Pennsylvania's engineers
developed a unique propeller with four
additional specially shaped blades these
generate large amounts of thrust but at
much lower speeds this way the
pennsylvania produces almost no
cavitation or propeller noise she is a
silent predator of the deep
after 75 days at sea the Pennsylvania
glides quietly back to base her patrol
20 years after her launch she is still
the biggest submarine in the Western
world and she will remain so until
someone builds an even bigger one
