Los espacios los escribimos con el simbolo +

Se puede añadir otra forma de búsqueda que no se a qué se corresponde y es: &oq=y+el+mismo+texto

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=isch y para vídeos &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.

Once our hatch is closed to dive, a crew are sealed inside the submarine for the duration of their mission.

 

Why our t  ?¿?¿?

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

fair water planes

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

propels itself

it's powered by a tank of compressed air

on launch a valve opens

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

electric motor

but it needs an enormous battery to

power it to accommodate the battery the

torpedo needs to be over seven meters

long

restore your Lord on a pity River

the Pennsylvania's mark 48 torpedo

are not limited to firing in a straight

line these high-tech robots can be

guided on to their target shut to -

ready now respects fire for procedures

cr7 tube - solution ready chef ready

weapon ready shoot - to set shoot you -

fuck

an optic fiber spooling out of the back

of the torpedo carries the weapons

officer's commands

this allows him to steer the torpedo

towards the target

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

Atlantic

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

fuel go further

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

rotate at high speed

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

uranium fuel

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

stay at sea is food

so it's fuel for the crew rather than

for the submarine that limits the range

of the Pennsylvania she carries a three

month supply and it's some of the best

Chow in the Navy trapped underwater in a

steel tube foods also an important

morale booster for the crew Saturday

night is pizza night BBQ freeway even

during mealtimes the crew are on

constant alert let's burn marks for fire

masini wine and fire from the grandpa

controller down the general arm the

greatest fear for submariners is fire so

they run through fire drills as

regularly as they eat pizza

Ecco defeated with me to record fires on

mercy

they've learnt their lesson from the

Russian submarine Kursk she sinks in

2000 with the loss of all hands

when she's brought up from the bottom

it's clear that her crew had taken too

long to control a fire and the submarine

had exploded

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

rocket-powered atom bomb

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

first to do it

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

bomber

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

white sounds are alarm

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

message the direction launch of target

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

President himself

come the message is authentic I concur I

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

them through the water

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

combined

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

except us

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

lot of noise

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

water increases

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

created on the blades

this lowering of pressure causes the

water to boil without heating up and

produces bubbles of steam this is called

cavitation

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

completed

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
