since the industrial revolution,

factories have often been portrayed

as dirty and dangerous places...

Churning out products at the expense of the work force.

But one American factory is challenging this view...

...the Tesla factory.

Located in Fremont, California,

this state-of-the-art automotive manufacturing facility

is kick-starting a new technological era.

And Tesla's Alexis Georgeson has witnessed the birth

of this giant industrial machine.

The processes here, in this factory,

are designed to be as efficient as possible.

It's a 5.3 million square-foot facility.

This American car manufacturer

revolutionized the industry

with the world's first electric sports car.

But producing hundreds of thousands of electric cars

for mass consumption

required an even greater scale of engineering.

That's one of the biggest challenges ahead,

as our CEO Elon Musk has said,

is really building the machine that makes the machine.

Starting production in 2012,

this machine is the biggest factory

in the western hemisphere.

The 5.3 million square-foot factory

employs 6,000 workers and state-of-the-art robots

to transform raw materials into high-tech vehicles

in just a few days.

Here, the staff and some of the world's mightiest machines

come together to cast, stamp, paint, and assemble

component parts into 2,000 cars every week.

That's before they go through the final lap

on the factory's dedicated test track.

But making this many cars in a factory this big

would have been impossible without mass production.

We're rethinking the way

that the automotive industry

has approached production in the past,

through first principles of physics

and through vertical integration

and just really treating this

as an engineering problem, first and foremost.

Once upon a time,

there was no such thing as mass production.

Sword, please.

Everything was made by artisans.

Thanks, peasant.

Though charming and unique...

Tada! hmm.

...the process was inconsistent...

What a chopper.

Mine's a tiddler.

...expensive...

More.

More.

More!

...and slow.

With this approach,

making mass quantities of products was impossible.

What's this?! Gah!

But a revolutionary change was on the horizon.

Architect and historian Benedetto Camerana

is in the iconic city of Venice, Italy,

to reveal where mass production got its start.

In the middle ages, the Republic of Venice

was a political power

with a strong reputation for war and conquest.

The strength of the venetian empire

was based on naval muscle and commercial trade.

Both needed ships and lots of them.

Naval boat building had been carried out

in different shipyards

sprawled throughout the city.

That could take weeks to produce a single galley.

And that was not fast enough.

In the 12th century,

the Venetians developed a game-changing solution.

And this is it...

the Venice arsenale.

Here, they completely re-imagined the way

that ships were built.

For the first time in history,

each individual component of a ship was mast produced...

Across a centralized row of specialized workshops.

The ships were moved around the dockyard

to different workshops.

Each focused on pre-fabricating

the different elements of the ship.

Hulls were made and launched as shells.

They were then towed across the shipyard and equipped

with ready-made masts, rudders, and anchors.

At the final workshop,

they were rigged and set up with oars and armaments.

At its height, they could assemble a galley per day here,

which is truly incredible.

At the arsenale,

venetian shipbuilders invented the production line.

And bringing this production line into the 20th century,

engineer Giacomo matte-Trucco

designed another one-of-a-kind factory

in Turin, Italy,

for the car company fiat, called the lingotto.

When it was completed in 1923,

this was the largest car factory in the world...

five stories high.

For the first time, all aspects of production

came together in a single building.

Specialized workshops were

placed strategically on each floor,

producing parts that would be fitted to the vehicles

as they progressed through the 1,600-foot-long factory.

Raw materials would arrive by rail

to the ground floor of the building.

Here, they would fashion the car components.

On the second floor,

the engines and bodies of the car were made.

One story up, gearboxes and steering were added.

The fourth floor specialized

in brakes and upholstery.

And on the fifth floor, finishing touches were made.

Finally, the completed cars would emerge on the roof...

the most iconic feature of the building.

All the cars coming off the lingotto production line

came here, a purpose-built rooftop test track.

For nearly 60 years,

this phenomenal test track high above the Turin skyline

would have been witness

to the birth of hundreds

of thousands of cars.

For over 50 years, the lingotto factory produced

countless vehicles until 1979.

But its tremendous legacy lives on.

At the Tesla factory in Fremont, California,

the principles of mass production,

first applied at the Venice arsenale

and further developed at the lingotto,

are getting a 21st-century makeover.

We move cars from one end to another.

So much of the factory is vertically integrated.

We're actually producing so many components here, in house,

rather than shipping them from other parts of the world

or other parts of the country.

While the production line principles remain the same,

compared to factories of the past,

the Tesla factory is practically unrecognizable.

We wanted this, first and foremost,

to be a beautiful working environment

that really was a testament to the quality of the products

that we were building here.

So we came in, we repainted the entire space,

we put sunlights in the roof.

We wanted a lot of natural light

and a place where workers could come

and be proud of the craftsmanship

and the space where they were creating these products.

But to create a truly futuristic factory,

filled with cutting-edge robots,

the engineers had to draw

on the great innovations of the past...

The robot is correcting itself to achieve its objective.

...to deliver more impossible engineering.

The Tesla factory.

As the largest industrial plant in America,

this cutting-edge electric car company

has one of the most advanced production lines on the planet.

The 5. 3 million square-foot factory

takes raw materials in at one end,

and in as little as three days,

transforms them into cars.

6,000 workers interact

with the most futuristic technologies

to produce a staggering 2,000 electric cars a week,

all of which go through the final lap

on the dedicated test track.

But to produce vehicles on this vast and ever-growing scale,

engineers had to design with extreme economy.

How do we streamline this?

How do we ramp production?

How do we keep the costs down?

And how to do we make this manufacturing process

as efficient as possible?

To be ultra efficient, the engineers looked

to one of modern history's great breakthroughs...

...robots.

Science communicator Kate Mulcahy

is in southwest England

to find out how a scientific investigation

into brain function

actually led to a breakthrough in robotics.

Oh, lord, alive!

As I attempt to cross this beam,

signals are being sent to my brain

through my eyes, my inner ears,

and my sensory systems.

This feedback helps me to correct my weight distribution,

and, hopefully, I won't fall.

Each time Kate feels herself losing her balance,

he senses warn her.

This sensation is something

that scientists call negative feedback.

Yes!

For decades, scientists tried to incorporate

this negative feedback into robots

so that they could direct themselves.

And in 1948,

American-born neuroscientist William Grey Walter

had a breakthrough

and invented a truly pioneering robot.

And here it is!

Each machine contains two valves,

two relays, two motors, and two sensors...

one for light, and one for movement.

So, essentially, it's a two-cell nervous system,

which, when you think about it,

compared to the billions of nerve cells

that are in our brain, isn't that many.

But it still did something really amazing.

Grey Walter called his device the tortoise.

The tortoise's sensors are designed to sense the light

and move towards it.

So...

You can see it heading towards the light bulb right now.

The tortoise uses a photo-electric cell

to detect the light.

That's the sensor you can see on top of it,

moving back and forth.

When it registers the light, it stops the steering

and moves towards it.

Because there are different light sources

in the room,

the tortoise regularly stops to check its position

before adjusting its direction

to move closer to the brightest light.

So, that's negative feedback.

Just like when I was balancing on the beam

and adjusting myself,

the robot is correcting itself to achieve its objective.

Now, if we put obstacles in its way,

things get really interesting.

The shell of the robot now acts as a bump sensor.

So it's making decisions based on two sensors...

one is sensing the light,

and the other is detecting the obstacles.

Though it may look simple,

this is actually complex behavior.

The tortoise has a different solution

ever time the experiment is run,

and each path it takes involves

a multitude of different

corrections and movements.

Every reaction they make

is a result of sensing the environment around them.

Then, they react and create a new path.

Amazing!

For the first time, a machine could demonstrate

a complex decision-making process,

and this discovery paved the way

for a revolution in robotics.

Autonomous machines have come to replace humans in many realms,

from the domestic to outer space.

And they've revolutionized the industrial world.

But at the Tesla factory in California,

engineers are integrating robots and workers

to a much greater degree

than the factories of the past...

Making it one of the most automated facilities on earth.

Some robots here even resemble Grey Walter's

breakthrough tortoises.

We've solved a tough logistics problem

in the factory, too, with the use of robots.

So our cars actually move around several sections

of the process of production

on these little smart carts.

Their robots that actually

follow these magnetic strips in the floor,

and they move from one section to the next,

following these little strips.

Also using negative feedback,

these robotic vehicles use sensors

to spot people or objects in their way

and wait until the path is clear.

Incredibly, they take themselves out of rotation

when their batteries run low

and put themselves back when fully recharged.

And this simple guidance system

allows their routes to be adapted instantly.

But these carts are relatively primitive

compared with most of the factory's robots.

The robots behind me are kuka robots.

They're actually trained to do up to five tasks.

They rivet, they weld, they glue, they move pieces

from one part of the line to the other.

So they're incredibly smart robots.

Hundreds of the kuka robots

perform amazingly complex but repetitive tasks

with incredible precision...

And without ever getting bored.

But when it comes to heavy lifting

and carrying 5,000-pound cars dynamically,

engineers at the Tesla factory

had to develop even more serious heavyweights...

So most conventional robotic arms

that you'd find on the market

wouldn't be able to lift weights

nearly as close to this one.

...to make the impossible possible.

The Tesla factory.

As the largest industrial plant in the western hemisphere...

...this technologically- advanced facility

uses cutting-edge robots to help produce an astonishing

2,000 electric cars every week.

But for robots to actually lift and rotate 5,000-pound cars,

engineers had to rely on a breakthrough innovation.

This is one seriously impressive robot.

This is the Fanuk M-2000ia/1200

multi-arm manipulator.

Now, this robot is so strong,

it's capable of doing four times the work

of a conventional robot.

It's able to lift a really impressive 1.2 tons,

and it's used on the Tesla assembly line.

But its bigger brother,

which is also in use on the Tesla assembly line,

can lift a huge 2.3 tons.

Now, that's really useful

if you want to move a car in a single lift.

So most conventional robotic arms

that you'd find on the market wouldn't be able to lift weights

nearly as close to this one.

On top of that, this robot is capable

of running 24 hours a day

and seven days a week.

Yes! it's working!

Traditional ways of moving heavy weights,

such as lifts or hoists,

can only go up and down, whereas this,

because of its six different axes,

allow this robot to move with unbelievable accuracy.

And it's exactly this that Tesla uses

to save them both time and money,

and to ensure that cars

can keep rolling off their production line.

And all of that make this

a truly incredible feat of robotic engineering.

12 of these heavyweight robotic arms

use the six different axes

to provide both flexibility and sheer power

to keep the car production going.

Named after superheroes, the likes of Wolverine

and ice man continually lift up these heavy cars

without breaking a sweat.

Robots are incredibly valuable

in the automation of this process

at helping us to ramp production

and to make this process as seamless as possible.

But robots aren't the only remarkable machines

required for a 21st-century car factory.

To produce hundreds of thousands of electric cars,

Tesla's engineers must continually satisfy

a very modern challenge.

All of this is an effort to indulge

as many electric vehicles and get them on the road

as quick and seamless as possible.

The Tesla factory in Fremont, California,

is the largest industrial plant

in the western hemisphere.

This futuristic facility

produces over 2,000 electric cars

every week made of aluminum.

But to shape the vehicles with this material,

engineers had to rely on an inventive

manufacturing process from the past...

the industrial press.

Today, bicycles are everywhere.

But when they first appeared, they were strictly for the rich.

Historian Chris sweet is on the trail

of the industrial innovation

that brought bicycles to everyone.

Late-19th century bikes were luxury items,

costing up to $100 each.

That was as much as an average worker would make in six months.

But all that changed here, in Chicago.

In the late 19th century,

entrepreneur Adolph Schoeninger

revolutionized how bicycles were made.

Because early metal bicycles were manufactured

using a cumbersome process,

Schoeninger hoped to improve the building technique.

Traditional method of making bicycle components

was known as drop forging.

It involved taking a chunk of metal

and heating it till it was malleable,

like this chunk of Clay,

and forging it into shape by repeated pounding.

It was a long, labor-intensive, and expensive process.

That is what Schoeninger wanted to change.

And this is what he did.

He came up with an industrial press

to shape cold steel.

Imagine this sandwich maker is our press.

You put in a sheet of cold steel...

Press it.

Out comes a three-dimensional bicycle component

ready to be assembled and painted.

By pressing bicycle components

with an industrial press instead of forging them,

Schoeninger slashed the prices of its bicycles,

finally making them affordable to the general public.

Soon, Schoeninger's western wheel works

was turning out 70,000 bikes a year,

with markets as far away as Europe,

transforming Chicago

into the bike capital of the world.

And his methods were picked up and used by Henry Ford

and other pioneers of the automotive industry.

The mass stamping of parts revolutionized manufacturing

in America and around the world.

At the Tesla factory, engineers have super-sized

Schoeninger's revolutionary industrial press

to shape the cars.

This is one of the largest hydraulic stamping presses

in north America.

It's actually seven stories high.

We can only see four stories.

Three of them are actually underground.

There are five main sections of this press,

each one weighing up to about a million pounds.

The giant stamping press uses a variety of heads

to turn the flat sheets of aluminum

into all kinds of ultra-lightweight

car body parts.

And cold-forming the aluminum helps preserve

the physical strength of each component.

You need a machine that can exert a ton of pressure

and force down on those panels without a lot of heat.

That's what this hydraulic press is capable of doing.

We take those sheets of aluminum that you saw,

and they're actually stamped between four to five times

as they move down here.

This powerful press is capable of exerting

around 9,000 tons of pressure per square inch,

the equivalent of having 3,000 cars

pressing down on your thumbnail.

The seven-story-tall monster press

can create strong, complex shapes quickly

and at a much lower cost than other techniques

like hot forming or machining.

This is an incredibly important machine to us

to help stamp the individual parts

for model S and model X.

They're electric vehicles,

and they're already very heavy cars

because battery packs weight a lot.

So it was important that the other parts of the vehicle

be as light-weight as possible for efficiency.

The aluminum panels make the range and the safety

very, very possible in these cars.

But these fresh-pressed panels

must also be painted.

So how do you efficiently paint 2,000 cars a week

without waste?

This would have been impossible

without the innovation of electrostatic painting.

To reveal the origins of industrial painting,

physicist Suzie Sheehy

is visiting an inner-city graffiti workshop

where the inefficient use of paint is clear.

Spray painting is a brilliant way

to cover a surface area

with an even coat of paint.

But as any graffiti artist can tell you,

it's pretty messy and inexact.

As the paint particles are released

from the pressurized canister,

they have a tendency to go everywhere,

all over your hands and the floor.

That's leads to a lot of wasted and scattered paint,

which is both costly and inefficient.

During the depression of the 1930s,

Harold Ransburg was working at his father's house ware factory

when he saw how much industrial paint

was simply getting wasted.

This salt shaker is exactly the kind of article

that Ransburg was trying to paint.

So if I try and paint it...

...you can see there's a lot of mess

and a lot of wastage,

and I haven't even really achieved a very good finish.

And you can imagine on an industrial scale

how expensive that would be.

So with lab assistant Harry green,

Ransburg experimented with electrical currents.

Because negative and positive charges attract each other,

Ransburg and green introduced

an electrical charge to the painting line

in order to attract all the paint to the product

without waste.

And in 1938,

Ransburg spent all the money he had, $35,

to buy a high-voltage transformer

typically used in hospital X-ray machines.

I'm gonna use a Van Der Graaf generator instead,

but the principle is more or less the same.

This generator uses a moving belt

to build up an electrical charge in a hollow metal globe.

To if I connect this up, that will give a positive charge

to the shaker

and then the paint, which is still neutral,

is gonna become attracted to it...

at least, that's the theory.

All right. So, if I just ground the paint tin.

Switch it on.

Let's see.

Oh, that's great.

So it's actually coating all around the sides.

It's actually pulling the paint all around,

onto the back.

It's got a really good coverage,

and, actually, there's a lot less paint wasted, as well.

Called electrostatic painting,

Ransburg's pioneering technique

transformed industrial painting across the world.

You might not realize it,

but electrostatic painting

is used to decorate all kinds of everyday objects...

from shop fronts to railings,

lamp posts to bicycles.

We are surrounded by the fruits

of Harold Ransburg's innovative approach to painting.

80 years on,

the Tesla factory has taken electrostatic painting

to a level that Harold Ransburg

could only have dreamed of.

In a state-of-the-art paint shop,

each car is attached to an electricity source

and grounded.

Robots spray positively-charge paint

that is electrostatically attracted to the car.

Primer, color, and, finally, a clear coat

are efficiently applied with very little waste

to create a completely flawless finish.

But mass producing electric cars effectively and efficiently

isn't the only challenge the factory faces.

To surpass the high expectations of the car-driving public,

Tesla's engineers had to overcome

the historic problems of the electric car...

20 miles an hour.

I'd say that's about as fast as I'd like to go.

...to create even more impossible engineering.

In California, Tesla's engineering innovators

are in the process of creating the factory of the future,

attempting to turn the more-than-century-old

automobile industry on its head.

They're using advanced robotics and technology

to bring back the electric car

and transform it from a niche item

to an everyday mass-produced product.

Everything about the 5.3 million-square-foot facility

is designed for speed, accuracy, and efficiency.

But technical advances aren't the only challenges

the factory faces.

It must also turn out a vehicle that the public,

who are used to the speeds and distances

that internal-combustion engines provide,

will actually want.

Hmm.

In 1908, Henry Ford had a bright idea...

Aha!

...to bring the internal-combustion engine

to the people.

The revolutionary technology changed the world...

Demand for gasoline went through the roof.

I'm rich!

Cities swelled as new suburbs

within reach of the workplace grew.

Hi, honey! I'm home!

Modern life quickly centered around

the internal-combustion engine.

And people could go faster...

And further than ever before.

But once upon a time,

the combustion engine had a surprising rival...

the electric car.

This is a pope-waverley.

Built in 1901,

it's one of the world's first electric cars.

And this particular one was used by Harrods for deliveries.

Physicist Suzie Sheehy is taking a ride

on this classic piece of American engineering.

It's a little-known fact that at the turn of the century,

about a third of all cars were electric powered.

When the automobile was first invented,

there were three main forms of propulsion...

internal combustion, steam-driven,

and the popular battery-powered engines.

Now, this beautiful machine, in its day,

would have had a range of about 20 miles

and a top speed of a whopping 20 miles an hour.

But having driven in it for a while,

I'd say that's about as fast as I'd like to go.

But electric cars were soon eclipsed

because automobiles running on gasoline

developed a longer range, became more reliable,

and got much faster,

leaving the electric car in the dust.

But Tesla's designers and engineers believe

they've overcome the problems that held the electric car back.

To see how, rally race driver Alex Roy is

taking the model S out for a test drive.

Earlier generations of electric vehicles

didn't have the benefit

of batteries with decent power density.

It is the first time that you have an electric vehicle

that's a genuine sports car.

With the model S...

You can do this.

And that is Ferrari-level acceleration.

It's...

It's impressive.

The beating heart of the design

is the powerful electric motor.

And it couldn't be more different

from a traditional internal-combustion engine.

The standard gasoline engine has hundreds of moving parts.

But the motor on the model S and model X

only has one moving piece... the rotor.

Powering it are nearly 7,000 small lithium-ion batteries

packed into a tray that fits in the floor of the vehicle.

And to produce these batteries,

Tesla is doing something extraordinary...

...creating an even bigger factory,

the size of which has never been seen before

on planet earth.

It's still under construction.

We're building it in phases so that we can actually start

production of battery cells and packs inside

while we continue construction outside.

That factory will, once complete,

be the largest building in the world by footprint.

Called the Giga-factory,

this enormous solar-powered facility in Nevada

will take the mass production of batteries for electric cars

to an unprecedented scale.

Within a couple of years,

we'll be putting hundreds of thousands of battery packs out

every year.

These powerful batteries,

combined with radical automotive design,

allow the electric car to drive much further distances.

But to compete with the hundreds of miles

that gasoline-powered vehicles can go on a single tank of gas,

Tesla's engineers had to give the electric car

yet another source of power.

It's an absolutely brilliant piece of engineering.

And, suddenly... Science fiction isn't tomorrow,

it is today.

...to make the impossible electric car...

Possible.

The Tesla factory...

as the largest industrial plant in America,

this facility has produced and sold

over 200,000 electric cars worldwide.

But making a battery-powered vehicle

that can drive as far and as fast

as gas-powered cars

would have been impossible

without giving it more power.

Anyone who's ever ridden a bicycle...

Whoo-hoo!

...knows how much power is wasted

when you brake.

The kinetic energy from the bike's forward motion

is thrown away

as the brake pads rub against the tires,

converting that energy to heat.

Just how much energy is lost becomes painfully obvious

when you start pedaling again.

Determined to use the energy normally lost in braking,

Tesla's engineers have coordinated the motor

to work with the brakes.

When the brakes slow the vehicle,

the motor also acts as a generator

and converts the otherwise wasted energy into electricity,

returning it to the batteries.

This energy recycling process is called regenerative braking.

Regenerative braking is a technology

that grew out of racing.

And in formula 1, regenerative braking was

developed to make cars go faster.

In a Tesla, that extends the car's range,

and it's one of the reasons

the Tesla has a range of 300 miles

as opposed to earlier generations of electric cars,

which were restricted to 250, 200, even 150.

All this means electric cars

can now match the distances of gasoline-powered vehicles.

If you didn't have a regenerative braking system

dumping power back into the battery,

I would imagine you'd have somewhere between a, you know,

10% and 30% drop in range.

It's an absolutely brilliant piece of engineering.

And, suddenly... Science fiction isn't tomorrow,

it is today.

These trailblazing engineering innovations

would not be possible

without the giant cutting-edge factory

that builds them.

This extraordinary engineering process begins

with humble coils of aluminum sheets...

And ends just a few days later on the test track.

That can-do, think-outside-the-box

is really something that informs both the vehicle

and the factory side of the equation here at Tesla.

You'll see that both in the engineering of our products,

as well as the engineering and in our approach

to manufacturing and production within this facility.

By drawing from the great innovators of the past...

This was the largest car factory in the world.

Oh, that's great!

Amazing!

...adapting their ideas,

and making trailblazing discoveries of their own...

Every single manufacturer will be making a car

just like this with their own brand on it

within five years.

Things can be done better.

You don't have to be trapped in the past.

...the planners, designers, and engineers

behind this futuristic factory

are succeeding in making the impossible possible.

Being in this factory, certainly,

is something that, I think, every employee can agree

is something they're incredibly proud of.
