'Man has taken his greatest stride towards turning light into day.'

0:00:020:00:07

'The invention of microfilm has...'

0:00:070:00:09

'This is the software...'

0:00:090:00:11

'Identified as penicillium...'

0:00:110:00:13

'The laser beam has an information capacity...'

0:00:130:00:15

'The white heat of technology come to life...'

0:00:150:00:18

This is D-4, one of eight hangars

0:00:200:00:23

belonging to the UK's Science Museum,

0:00:230:00:25

a mind-boggling collection of hundreds of thousands of inventions,

0:00:250:00:29

all of which have changed our world.

0:00:290:00:32

Everything from steam engines to some of the very first computers.

0:00:330:00:38

I find this an inspiring place. A reminder of how inventive we can be.

0:00:400:00:45

But I've come here to find out about

0:00:470:00:49

some of the most exciting of today's inventions.

0:00:490:00:52

I am going to meet the men and women who are the driving forces

0:00:540:00:58

behind some of the inventions that are changing our world.

0:00:580:01:01

They're pioneers in four areas of science that are shaping our future.

0:01:030:01:08

But it's not just about the inventions themselves.

0:01:110:01:14

I want to know how they go about it, what inspires them,

0:01:140:01:18

how do they drive their ideas forward

0:01:180:01:20

and ultimately end up with a ground-breaking invention?

0:01:200:01:24

I am hoping to get a sneak preview of tomorrow's world.

0:01:250:01:29

For over a million years, this, a simple flint tool,

0:01:490:01:54

was the pinnacle of human invention.

0:01:540:01:57

It remained pretty much unchanged for 30,000 generations.

0:01:570:02:02

But in the past 150 years,

0:02:020:02:04

the pace of invention, from planes to rockets to smart phones,

0:02:040:02:08

has been extraordinary and it shows no signs of slowing down.

0:02:080:02:14

In the US alone, more patents have been filed

0:02:140:02:17

since the year 2000 than in the previous 40 years combined.

0:02:170:02:23

More scientific papers are being published globally year on year.

0:02:230:02:27

And more countries than ever before are getting involved.

0:02:270:02:31

Today anyone can innovate, anywhere in the world, whether that's

0:02:340:02:37

in the West in a garage or in Nairobi on a mobile phone.

0:02:370:02:41

Google, two guys from Stanford University wrote

0:02:410:02:44

a very simple algorithm that now is a multi-billion dollar company.

0:02:440:02:47

I think we're only at the very beginning of our journey.

0:02:470:02:51

If you like new ideas, and you like disrupting things,

0:02:510:02:54

and you like change and doing the new,

0:02:540:02:56

then there has never been a better time to be alive.

0:02:560:02:58

'We have...we have lift-off.'

0:03:000:03:03

I want to start with one area that has fascinated me

0:03:040:03:07

since I was a child -

0:03:070:03:10

the exploration of space.

0:03:100:03:12

It's an area which is being revolutionised

0:03:140:03:17

by 21st-century inventors,

0:03:170:03:20

like Peter Diamandis.

0:03:200:03:23

He started out as an engineer and physician,

0:03:260:03:30

but now he's an entrepreneur who's spearheading a new race to space.

0:03:300:03:35

OK, sure. OK.

0:03:360:03:39

Do you need me to draft...

0:03:390:03:41

And he has some friends in high places.

0:03:410:03:43

OK. It's the White House.

0:03:440:03:48

If I had to put one thing that inspired me,

0:03:500:03:53

it was the Apollo programme.

0:03:530:03:55

You know, seeing humanity going to the moon

0:03:550:03:58

and then seeing America stop going in 1972,

0:03:580:04:02

that really said, OK, they're not going.

0:04:020:04:05

What am I going to do to get us there?

0:04:050:04:07

The lunar programme was brought to a halt in part

0:04:100:04:13

because of the huge price tag.

0:04:130:04:15

The equivalent of over 100 billion in today's money.

0:04:160:04:20

Peter's challenge was to find a way to encourage the private sector

0:04:220:04:27

to pick up where the state had left off.

0:04:270:04:29

He found inspiration in one of history's great aviators,

0:04:330:04:36

Charles Lindbergh,

0:04:360:04:38

and his quest to be the first to cross the Atlantic solo.

0:04:380:04:41

One day a very close friend of mine gave me a copy of Lindbergh's book

0:04:430:04:47

and I read about the fact that

0:04:470:04:49

Lindbergh crossed the Atlantic in 1927 to win a prize.

0:04:490:04:52

I had no idea. He was going after a 25,000 prize

0:04:520:04:56

and that 25,000 drove nine different teams who spent 400,000,

0:04:560:05:02

16 times the prize money, going after that prize.

0:05:020:05:05

The idea of creating a space prize

0:05:050:05:08

for private space flight came to mind.

0:05:080:05:10

I called it the X Prize cos I had no idea who would put up the money.

0:05:100:05:13

The X was a variable to be replaced by the name of the sponsor.

0:05:130:05:17

It's a pleasure to celebrate the launch of the Google Lunar X Prize.

0:05:190:05:23

In 2007, Diamandis set up the Google Lunar X Prize.

0:05:260:05:30

It offers a 20 million reward to the first private team

0:05:330:05:37

that can successfully land a robot on the moon,

0:05:370:05:41

get it to travel 500 metres across its surface...

0:05:410:05:44

..and send data and high-definition images back to earth.

0:05:460:05:50

The Google Lunar X Prize is a competition that will demonstrate

0:05:520:05:56

that small dedicated teams of individuals can do

0:05:560:05:59

what was thought only once possible by governments.

0:05:590:06:02

One of the front-runners for the prize is Moon Express.

0:06:050:06:09

They're based here at Moffatt Field, California,

0:06:120:06:15

where they're using some of NASA's surplus research facilities.

0:06:150:06:19

Their CEO is Bob Richards.

0:06:200:06:23

The Google Lunar X Prize is a master stroke.

0:06:250:06:27

It's an inspiration and a motivation for small teams to try

0:06:270:06:31

what was only accessible to superpowers in the past.

0:06:310:06:34

What used to take thousands of people with slide rules

0:06:340:06:36

can now be done with young engineers sitting in a room

0:06:360:06:40

with desktop computers, and the spacecraft themselves can be

0:06:400:06:44

so much smaller because micro-miniaturisation of technology

0:06:440:06:47

has shrunk electronics and shrunk propulsion,

0:06:470:06:50

and this brings the economics into the realm of the private sector.

0:06:500:06:54

Moon Express's technology is already pretty advanced.

0:06:540:06:58

So this is the lander test facility that we use

0:07:000:07:03

to replicate the spacecraft and what it experiences on its journey to the moon,

0:07:030:07:07

all the way from Mission Control to its landing on the surface,

0:07:070:07:10

so we can actually make it think it's landing on the moon

0:07:100:07:13

and we can watch how it behaves and adjust all the software

0:07:130:07:16

so it just perfectly knows where it is and can land softly on the moon.

0:07:160:07:20

Their work isn't open to the public...

0:07:240:07:27

..yet.

0:07:280:07:30

The team have been designing unique landing gear

0:07:330:07:36

and cutting-edge miniature radar systems.

0:07:360:07:39

And the competition is attracting young scientists and engineers.

0:07:480:07:52

The project manager, Mike Vergalla, is just 27.

0:07:540:07:58

'What we're doing is taking commercial off-the-shelf parts

0:08:000:08:04

'and we're able to make a full vehicle in a very tiny package.'

0:08:040:08:07

Probably good to couple that with the RPMs.

0:08:070:08:10

Oh, you're in the red zone.

0:08:100:08:12

This is a small rover

0:08:120:08:14

with HD cameras there

0:08:140:08:17

and this little guy sits on the side,

0:08:170:08:20

and we land, pop him off and it goes and it explores.

0:08:200:08:25

It roves around and we're able to map,

0:08:250:08:26

look at items of interest, do sample collection,

0:08:260:08:29

try to do spectroscopy and learn about this new world.

0:08:290:08:33

And these are some of the other entries...

0:08:370:08:40

from all over the world.

0:08:400:08:43

To date, since the announcement,

0:08:500:08:52

we've had 25 teams from round the world who have registered to compete

0:08:520:08:56

from nearly a dozen nations.

0:08:560:08:58

And if you think about it,

0:08:580:09:00

there's only two countries have ever been to the moon -

0:09:000:09:03

the United States and the Soviet Union

0:09:030:09:05

and today any number of companies, individuals or countries

0:09:050:09:09

could go to the moon privately.

0:09:090:09:11

But private sector involvement means that these moon missions

0:09:160:09:20

have a more commercial edge than the Apollo programme.

0:09:200:09:22

We will be sending robotic landers initially to the surface of the moon

0:09:240:09:27

carrying scientific and commercial payloads.

0:09:270:09:29

Kind of a Fedex or a lunex model.

0:09:290:09:32

It's a transportation model.

0:09:320:09:33

Then we'll get into the era of exploring for resources and learning

0:09:350:09:39

how to process those resources, and bringing them back to earth.

0:09:390:09:42

After that we'll have the era of settlement, where people

0:09:420:09:45

will need to go there, and we'll have people living on the moon

0:09:450:09:48

and people will be born on earth to look up to the moon and to see

0:09:480:09:52

lights up there, and the children will know that mankind is not

0:09:520:09:56

limited to one planet, but we're actually now a multi-planet species.

0:09:560:10:01

I think the people who are working on the Google Lunar X Prize

0:10:030:10:06

are motivated by the dream,

0:10:060:10:08

the idea that they're part of humanity's expansion into space.

0:10:080:10:13

I mean, think about this -

0:10:130:10:15

millions of years from now, whatever humanity is,

0:10:150:10:19

they'll look back at these next few decades as the moment in time

0:10:190:10:23

when the human race irreversibly moved off planet Earth to the stars.

0:10:230:10:28

And people want to be part of that significant epic adventure.

0:10:280:10:33

Prizes in science have a long history,

0:10:350:10:38

but today, they've staged something of a comeback.

0:10:380:10:41

They're helping to drive innovation in areas from genetics

0:10:410:10:45

to environmental science.

0:10:450:10:47

Competition is really important when it comes to innovation

0:10:470:10:50

because all inventors are people, and people like to get there first,

0:10:500:10:54

they want to make all the money, and to do that,

0:10:540:10:57

you need to have some drive, some reason, some deadline.

0:10:570:11:00

People want to be known as the innovators.

0:11:000:11:03

They want to be known as the Jobs or the Neil Armstrongs,

0:11:030:11:06

and competition is a really good way of forcing people towards that.

0:11:060:11:09

The best inventors are people who are motivated,

0:11:110:11:14

not by making lots of money or building a business,

0:11:140:11:17

but by solving a problem.

0:11:170:11:19

And if the problem is well articulated in a prize,

0:11:190:11:21

that can be a real rallying cry and can bring people together.

0:11:210:11:24

What is striking is that today's private investors have ambitions

0:11:240:11:29

that only governments once dared to have.

0:11:290:11:31

But are a few tens of millions of pounds of prize money

0:11:310:11:36

really enough to be effective?

0:11:360:11:38

Mariana Mazzucato is an economist at the University of Sussex

0:11:410:11:45

who studies the economic forces that drive innovation.

0:11:450:11:49

What's very interesting in space is that we see this role

0:11:500:11:53

of the private sector today. They are calling themselves

0:11:530:11:57

the big risk-takers, the mavericks,

0:11:570:11:59

but the question is, would they be able to do

0:11:590:12:01

what they are doing today if they were not actually riding the wave

0:12:010:12:05

of major state investments in the early stages when space exploration

0:12:050:12:09

was actually much more uncertain than it is today.

0:12:090:12:12

So are there many other examples of industries that were

0:12:120:12:15

initially funded by the state and the private sector moved in later?

0:12:150:12:19

Yes. If you take, you know, one of the sexiest products out there,

0:12:190:12:23

the iPhone, it's really interesting that many people use the iPhone

0:12:230:12:27

to argue that this was created by the entrepreneurial spirit

0:12:270:12:29

of Steve Jobs but, in fact, the sort of key technologies behind it

0:12:290:12:33

that actually make it a smartphone were almost all state-funded.

0:12:330:12:37

I mean, the most obvious example is the internet.

0:12:370:12:40

The iPhone would not be as smart if it didn't have the internet,

0:12:400:12:43

which was funded by part of the US Department of Defense.

0:12:430:12:45

But even the nitty-gritty inside, and the microchips, were funded

0:12:450:12:49

by the military and space departments of the US government.

0:12:490:12:52

We have GPS, which is obviously also very important in the iPhone.

0:12:520:12:56

That was actually created through their satellite programme.

0:12:560:12:59

A multi-touch display was funded by two public sector grants,

0:12:590:13:03

and one from the CIA,

0:13:030:13:05

so, you know, all this great stuff inside the phone

0:13:050:13:08

which actually makes it smart, were funded by the public sector.

0:13:080:13:12

And without that, you would not have the iPhone today.

0:13:120:13:15

In a year or so, we'll know who gets to the moon and gets the cash.

0:13:160:13:21

The second area I want to explore is the world of materials.

0:13:250:13:30

After all, they define our technology.

0:13:300:13:34

From the mass-produced iron of the Industrial Revolution,

0:13:340:13:37

to the complex alloys of the jet age

0:13:370:13:40

and the silicon that underpins the information age.

0:13:400:13:44

Now we could be about to enter a new age, based on our ability

0:13:440:13:49

to manipulate matter at the smallest scale,

0:13:490:13:52

based on nanotechnology.

0:13:520:13:55

Not all inventions are a result of identifying a need

0:14:000:14:04

and coming up with a solution.

0:14:040:14:06

Sometimes, scientific discoveries are so radical and so unexpected

0:14:060:14:11

that it can take a while to realise their potential

0:14:110:14:13

for practical applications.

0:14:130:14:15

These innovations often rely on the mavericks of invention

0:14:150:14:19

who tend to look at the world in a very different way.

0:14:190:14:22

Yeah, so I guess it's liquid hydrogen...

0:14:220:14:26

'Like physicist Andre Geim.

0:14:280:14:30

'He shared the Nobel Prize for discovering

0:14:300:14:33

'one of the strangest new materials in the world.'

0:14:330:14:36

All Nobel Prizes rely on luck.

0:14:370:14:41

With a little bit more experience, you can drink liquid hydrogen.

0:14:410:14:45

'The more you try, the more chance that you get lucky.'

0:14:450:14:50

The best way to describe my approach is hit-and-run experiments.

0:14:500:14:56

There's a very simple idea, we try it, it doesn't work.

0:14:560:15:01

We go somewhere else. If it works, we carry on.

0:15:010:15:05

He's a man who's made tomatoes, strawberries

0:15:050:15:09

and even frogs levitate.

0:15:090:15:12

And who has designed a sticky tape based on the feet of geckos.

0:15:150:15:19

But for Andre, good inventions are about more than just good ideas.

0:15:220:15:29

99% of good ideas lead to nothing or to mediocre results.

0:15:290:15:34

What follows the idea - hard work, and what follows this idea -

0:15:370:15:41

this is important.

0:15:410:15:44

The journey that led Andre to the Nobel Prize

0:15:440:15:47

began with pure scientific curiosity about the world of the very small.

0:15:470:15:53

As a scientist, I was always interested in what happened

0:15:530:15:58

with materials when they become thinner and thinner.

0:15:580:16:02

Eventually, you reach the level of individual atoms and molecules,

0:16:020:16:06

and this is a completely different world.

0:16:060:16:09

Working with materials at these scales is a huge challenge.

0:16:100:16:15

Conventionally, scientists use complex and expensive machines

0:16:160:16:20

to manipulate atoms and molecules.

0:16:200:16:23

But Andre thought there had to be a better way.

0:16:250:16:28

It's very hard to move to a scale, OK, a thousand times smaller than

0:16:300:16:35

the width of your hair, because materials oxidise, decompose,

0:16:350:16:40

segregate, destroy themselves.

0:16:400:16:42

Something new had to be invented to study materials at a smaller scale.

0:16:420:16:47

For their experiment, they chose a widely available mineral -

0:16:490:16:53

graphite.

0:16:530:16:55

It's made up of sheets of atoms like the pages in a tightly-bound book.

0:16:550:17:00

But up until then, there was no easy way of peeling the layers apart.

0:17:020:17:08

We use a completely unorthodox, DIY, if you wish, approach.

0:17:080:17:13

One that required no hi-tech machines.

0:17:150:17:18

The easiest way to chop, we found, is to use Sellotape.

0:17:210:17:26

You put Sellotape on top of graphite and peel it off.

0:17:260:17:32

Then you put it together and make a fresh cut.

0:17:320:17:37

Essentially, it gets twice thinner,

0:17:370:17:41

so you make another cut and so on,

0:17:410:17:44

and then you ask yourself a very simple question -

0:17:440:17:49

how thin you can make graphite by repeating this twice,

0:17:490:17:55

twice, twice, and so on. What the thinnest material can be.

0:17:550:18:01

We looked at what is left on the Sellotape in a microscope,

0:18:050:18:10

and found, to our great surprise, films of graphite which were

0:18:100:18:14

in the range which we wanted to achieve.

0:18:140:18:18

It was a perfect hexagonal lattice

0:18:220:18:25

only one atom thick, called graphene.

0:18:250:18:28

But this material couldn't be more different to the pencil you hold

0:18:280:18:33

in your hand, because when you get down this small, everything changes.

0:18:330:18:38

We started studying properties of graphene

0:18:380:18:42

and then the real surprise came.

0:18:420:18:45

The properties turned out to be unique, and it was my eureka moment.

0:18:450:18:51

This material has 20, 30 superlatives to its name.

0:18:510:18:58

It's the strongest material that has ever been measured.

0:18:580:19:03

It's the most conductive material for electricity, for the heat.

0:19:030:19:07

It's the most impermeable material.

0:19:070:19:10

In fact, this nanomaterial is so different to anything we know,

0:19:130:19:18

it's hard to get your head around quite how powerful it is.

0:19:180:19:22

Graphene is so strong that if you take one-by-one metre of material

0:19:220:19:28

and make a hammock out of graphene,

0:19:280:19:32

it would sustain a cat, a one kilogram cat,

0:19:320:19:36

lying on this hammock, despite this material being only one atom thick.

0:19:360:19:41

It would be like a cat hovering in midair.

0:19:410:19:45

The discovery of graphene may sound like the purest of pure science,

0:19:520:19:56

but I want to find out from Andre's colleague, Sarah Haigh,

0:19:560:20:00

how it will lead to inventions that we can use every day.

0:20:000:20:03

So this is it, this is how you get graphene.

0:20:080:20:11

Is it still the most effective way to get that one atom-thick layer?

0:20:110:20:16

This really is still how we make the most perfect graphene sheets,

0:20:160:20:20

which have the best electronic properties.

0:20:200:20:22

And let's talk about, you know, those incredible properties.

0:20:220:20:26

I mean, how can something so small, one atom in thickness, be so strong?

0:20:260:20:31

it's to do with the bonds we have between the carbon atoms.

0:20:310:20:35

So this is a model of the structure of graphene,

0:20:350:20:38

and each of these black dots represents the carbon atoms.

0:20:380:20:41

The white lines are the bonds between them. And you can see

0:20:410:20:44

that each carbon atom is surrounded by three other carbon atoms,

0:20:440:20:48

and the bond between those carbon atoms is really, really strong.

0:20:480:20:51

And another very exciting property of course is its conductivity.

0:20:510:20:54

Why is graphene so conductive?

0:20:540:20:57

So the electrons inside graphene behave in a really unusual way.

0:20:570:21:01

They behave like they have no mass, and that means they can travel really, really quickly.

0:21:010:21:05

And do we know why that occurs?

0:21:050:21:07

It's really difficult to understand,

0:21:070:21:09

and there are still a lot of questions around exactly how

0:21:090:21:12

graphene has such amazing properties.

0:21:120:21:14

So when it comes to graphene's incredible conductivity,

0:21:140:21:18

does it have potential to replace what was a wonder-material

0:21:180:21:21

for conductivity, silicon? What's going on there?

0:21:210:21:24

We know that silicon has its limits.

0:21:240:21:26

We're going to reach a point where silicon transistors

0:21:260:21:29

can't get any smaller, they can't get any faster,

0:21:290:21:31

and graphene doesn't have the same limitations, and so it could be that

0:21:310:21:35

the next generation of electronics could be made out of graphene.

0:21:350:21:38

But rather like when we first had the original computer switches,

0:21:380:21:42

like this one here,

0:21:420:21:44

and now we're able to produce electronic chips that have

0:21:440:21:49

thousands of these switches built into this tiny chip.

0:21:490:21:52

That change required a whole new way of thinking,

0:21:520:21:55

and using graphene in electronics

0:21:550:21:57

is going to require the same sort of revolutionary new approaches.

0:21:570:22:00

Are we being a little bit impatient?

0:22:000:22:02

We are, but that's because graphene has such potential.

0:22:020:22:05

And there are people working on graphene all round the world,

0:22:050:22:08

thousands of different researchers who are trying to exploit

0:22:080:22:11

the properties, so much so that there are hundreds of papers

0:22:110:22:14

being published every single week, and they are continuing

0:22:140:22:18

to throw up new ideas and new suggestions for applications.

0:22:180:22:21

The speed at which ideas now move around the world

0:22:240:22:28

is one of the defining characteristics of invention today,

0:22:280:22:31

but another is the degree of specialisation it takes

0:22:310:22:35

to make these advances in the first place.

0:22:350:22:39

When you think about all the science that lies behind innovation today,

0:22:410:22:45

it's so complex and so advanced,

0:22:450:22:48

it seems impossible to be able to stay on top of everything

0:22:480:22:52

that's happening, and so, to keep the pace of invention up,

0:22:520:22:55

scientists have to work in a very different way

0:22:550:22:58

to that of lone scientists in the past.

0:22:580:23:01

Certainly, science has become so specialised now

0:23:020:23:05

that it's impossible to be an expert in all areas.

0:23:050:23:08

Once upon a time, there was just one science journal.

0:23:080:23:14

Today, there are over 8,000.

0:23:140:23:16

I reckon no scientist knows what other scientists are doing.

0:23:190:23:23

They might have some basic idea of the background,

0:23:230:23:25

but right at the cutting edge, there's no way they could keep up with each other.

0:23:250:23:29

When I'm researching stories,

0:23:290:23:30

sometimes I'll just see something and think, "What is that?!"

0:23:300:23:34

Or I'll have a scientist on the phone, be talking to him and

0:23:340:23:36

just be frantically Googling as he's saying things to try and keep up.

0:23:360:23:40

Look at the Nobel Prize.

0:23:400:23:42

When you read the citation for what somebody's done, it very often

0:23:420:23:46

is totally non-understandable to the average person.

0:23:460:23:50

Indeed, the simple categories we remember from school have now

0:23:500:23:55

multiplied into a complex web of interconnected fields,

0:23:550:23:59

each with their own highly specialised subject areas.

0:23:590:24:02

Quantum optics in photonics in nanotechnology.

0:24:040:24:08

Genomics, that's about genes, but I never did Biology O-level,

0:24:080:24:12

so that's one of my weak areas!

0:24:120:24:14

-INTERVIEWER:

-Systems biology?

0:24:140:24:16

Er, yeah, I think I could... Systems biology... No.

0:24:160:24:19

Quantum teleportation, quantum cryptography.

0:24:190:24:23

Neuroelectrodynamics.

0:24:230:24:24

It seems to make sense but I've never actually... What does it do?

0:24:240:24:27

I think that is using electric currents to make the studies

0:24:270:24:30

of nerves, repair nerves, look at nerves, all that stuff. I think!

0:24:300:24:34

-Transcriptomics, never heard of it.

-INTERVIEWER:

-Bioelectrochemistry?

0:24:340:24:38

I think it's the study of how you can use electro... OK, I have no idea.

0:24:380:24:42

One thing is clear - in a highly specialised world,

0:24:420:24:47

scientists and technologists have to collaborate to create

0:24:470:24:51

the next generation of inventions,

0:24:510:24:54

and one field where this is already happening with enormous success

0:24:540:24:57

is biomedical engineering.

0:24:570:25:00

Cambridge, Massachusetts.

0:25:060:25:09

This is Professor Bob Langer,

0:25:090:25:12

one of the most inventive scientists working today.

0:25:120:25:16

Over a hundred million people have benefited from his innovations

0:25:160:25:20

in cancer and heart research, so we spent a day with him

0:25:200:25:25

at his lab at MIT to find out how he does it.

0:25:250:25:30

This one is a National Medal Of Science.

0:25:300:25:32

That's given to you by the President.

0:25:320:25:35

That's the highest scientific award in the United States.

0:25:350:25:38

And Draper Prize up there.

0:25:380:25:41

That's often considered the Nobel Prize of engineering.

0:25:410:25:44

With over 800 patents to his name, not surprisingly,

0:25:470:25:51

Langer is a little hard to keep up with.

0:25:510:25:54

Well, that's not open.

0:25:540:25:56

Leon. So this is Dr Leon Bellan. What is the number?

0:25:560:25:59

Can we go...? Yeah, we'll go to take a look at Leon's lab and...

0:25:590:26:05

Dr Bellan is using some rather unconventional lab equipment.

0:26:050:26:10

This is actually very cool stuff.

0:26:110:26:13

Let's plug this guy in.

0:26:150:26:18

What Leon's been able to do is convert a 40 cotton candy machine

0:26:180:26:22

into something that can make all kinds of scaffolds

0:26:220:26:24

for regenerative medicine and tissue regeneration.

0:26:240:26:28

This will take a while to warm up, so this is just some sample

0:26:280:26:32

cotton candy-like material that's used to make artificial capillaries,

0:26:320:26:38

basically the smallest blood vessels in your body.

0:26:380:26:40

This is extremely cheap micro-fabrication.

0:26:400:26:43

-Yeah, and it works.

-And a high throughput, yes.

-And it works.

0:26:430:26:46

Langer's signature approach is

0:26:460:26:48

to bring people from different scientific disciplines together.

0:26:480:26:54

It all started for him with a search for new materials for medicine.

0:26:540:26:59

Pretty much all the materials in the 20th century

0:26:590:27:01

that have been used in medicine, when I looked at it,

0:27:010:27:04

largely were driven by medical doctors

0:27:040:27:06

who would go to their house and find an object that kind of resembled

0:27:060:27:10

the tissue or organ they were trying to fix. So if you look at this,

0:27:100:27:14

the artificial heart, that started actually in 1967

0:27:140:27:19

with medical doctors saying "Well, what has a good flex life?"

0:27:190:27:23

They actually picked a lady's girdle and used the material in that.

0:27:230:27:27

But those materials can sometimes cause problems.

0:27:270:27:30

For example, the material in the artificial heart,

0:27:300:27:32

when blood hits that, it can form a clot, and that clot can go

0:27:320:27:36

to the patient's brain and they could get a stroke and die.

0:27:360:27:39

So I started thinking, could we have materials that we could specifically

0:27:390:27:42

design for medical purposes rather than just taking them off the shelf?

0:27:420:27:47

When Langer started over 30 years ago,

0:27:480:27:51

his big idea was to design new materials - polymers -

0:27:510:27:55

that could go inside the body and carry out all sorts of

0:27:550:27:59

medical procedures before dissolving safely,

0:27:590:28:03

like delivering drugs or acting as scaffolds for growing new skin,

0:28:030:28:08

bone and cartilage.

0:28:080:28:10

The problem was it had never been attempted before.

0:28:100:28:14

When we first started this,

0:28:140:28:16

people said that we wouldn't be able to synthesise the polymer.

0:28:160:28:18

The chemists said it would be too difficult or couldn't work.

0:28:180:28:21

They said the polymers will break in the body, they're fragile,

0:28:210:28:24

and people said it wouldn't be safe.

0:28:240:28:27

It involved polymer science, chemical engineering

0:28:270:28:30

and chemistry and pharmaceutics and pharmaceutical science.

0:28:300:28:33

It involved also neurosurgery and pharmacology,

0:28:330:28:35

medicine and radiology, and toxicology.

0:28:350:28:39

This collaboration turned out to be a success, and here's the proof.

0:28:390:28:45

These are polymer wafers being put into someone's brain

0:28:450:28:49

to treat a tumour with targeted drugs.

0:28:490:28:52

Devices like these have now become a routine part of treating cancer.

0:28:520:28:57

One of Langer's key collaborators is neurosurgeon Henry Brem.

0:28:570:29:02

The patient goes home three days later.

0:29:020:29:06

They're not sick from chemotherapy, they don't lose their hair,

0:29:060:29:09

they don't throw up, they don't have

0:29:090:29:12

any of the typical, sad side effects of chemotherapy,

0:29:120:29:16

and yet they have a very effective drug that's working on their behalf.

0:29:160:29:21

Langer's way of drawing people together is proving to be

0:29:210:29:25

an immensely powerful way of driving innovation in 21st-century science.

0:29:250:29:30

The way we have developed the interdisciplinary approach, really,

0:29:300:29:33

is the people I have in the lab.

0:29:330:29:35

We probably have people with about ten different disciplines.

0:29:350:29:38

Hey, Chris, I'll look forward to seeing you later, but also, I gave you comments.

0:29:380:29:42

-Yes, I saw that. Thank you.

-OK, great.

0:29:420:29:44

'I think the big advantage of trying to do interdisciplinary research is'

0:29:440:29:47

you can take things that are, say, in engineering

0:29:470:29:50

and apply them to medicine and vice versa.

0:29:500:29:53

So, you have the possibility of going down avenues and roads

0:29:530:29:57

that other people just wouldn't go.

0:29:570:29:59

In fact it's hard to find anyone in this lab

0:30:020:30:05

who's got just one area of expertise.

0:30:050:30:08

Hey, I'll be right there.

0:30:080:30:09

And Langer is always hunting for new collaborators, like Dr Gio Traverso.

0:30:110:30:17

He's got incredibly neat stuff.

0:30:170:30:19

He's actually the perfect example of somebody

0:30:190:30:22

who's super-interdisciplinary.

0:30:220:30:24

I'd say now he's got medicine, molecular biology, and engineering

0:30:240:30:29

all in one person so he'll tell you a couple of things that he's doing.

0:30:290:30:33

They're actually amazing.

0:30:330:30:34

-One of the things that we're working on, we're developing...

-And all these are inventions.

0:30:340:30:39

We're developing a series of ingestible devices,

0:30:390:30:42

which are actually coded with different needles.

0:30:420:30:45

Here the needles are actually fairly long so they're getting smaller

0:30:450:30:48

and shorter as we progress with the development.

0:30:480:30:51

When devices like this can be sufficiently miniaturised,

0:30:510:30:54

external injections might become a thing of the past.

0:30:540:30:58

So, are you working on a vaccine, or on bubbles, or which?

0:31:040:31:08

-Right now on the bubbles.

-OK.

0:31:080:31:10

Bob's mind works very differently than the rest of us.

0:31:100:31:13

He sees the world as a song, as an orchestral piece

0:31:130:31:18

and he is the ultimate conductor.

0:31:180:31:20

He knows what it's supposed to sound like, and at the end of the day,

0:31:200:31:25

he can have all of us play

0:31:250:31:28

so that what we produce is not only harmonious,

0:31:280:31:32

but each individual player, so much better than we could ever have done alone.

0:31:320:31:38

You'll find something. If it works, that's a good thing, but obviously

0:31:380:31:42

-if it works according to theory, that's a better thing.

-Yeah, yeah.

0:31:420:31:45

After almost four decades, Langer's method now provides

0:31:490:31:54

something of a blueprint for the rest of the scientific world.

0:31:540:31:58

I think the days of an individual working in a garage

0:31:580:32:02

and coming up with major inventions that really make an impact are over.

0:32:020:32:06

It's teams now of people with a unified purpose that work together,

0:32:060:32:10

and you build on everyone's expertise.

0:32:100:32:13

Eight hours later and Bob Langer is on his way home,

0:32:140:32:18

but I don't think he's finished his work just yet.

0:32:180:32:20

It seems that collectively we can do far more

0:32:240:32:27

than even the most brilliant individual,

0:32:270:32:30

and now a new breed of inventors

0:32:300:32:32

is taking this interdisciplinary approach a step further

0:32:320:32:36

by using the internet to develop a concept on a global scale.

0:32:360:32:40

One of them is Cesar Harada,

0:32:420:32:44

an inspirational young inventor who's been tapping

0:32:440:32:47

into the true power of the internet, the power of the crowd.

0:32:470:32:52

His invention came as a result of one of the biggest

0:32:570:33:00

environmental disasters of the last decade -

0:33:000:33:03

the Deepwater Horizon oil rig explosion of 2010.

0:33:030:33:07

Millions of barrels of crude oil poured into the Gulf of Mexico

0:33:090:33:13

and the race was on to clear up the mess.

0:33:130:33:16

Cesar Harada wanted to help,

0:33:190:33:22

but he'd just won a coveted place at MIT.

0:33:220:33:25

As events unfolded, he faced a difficult choice.

0:33:250:33:28

I was watching TV, and I was, er, terrified and sad,

0:33:310:33:36

and my response was to leave my job,

0:33:360:33:41

my dream job in MIT, and move to New Orleans

0:33:410:33:43

and try to develop technology to clean up the oil spill.

0:33:430:33:46

Cesar believed that the fishing boats adapted with skimmers,

0:33:470:33:51

which were being used to clear up the spill, weren't up to the job.

0:33:510:33:55

The tools they were using to capture it are these small fishing boats

0:33:560:33:59

and they capture some of the oil,

0:33:590:34:01

but imagine if you're swimming into an ocean of oil and you're just

0:34:010:34:04

extending your arms like this, you're not going to catch very much.

0:34:040:34:07

It's such a big surface.

0:34:070:34:08

What's more, when seas were rough, no skimming could take place.

0:34:100:34:14

So obviously there were many problems to cope with,

0:34:170:34:20

but how did you go about it? What were you mainly focusing on?

0:34:200:34:23

The first was to remove human beings from the...from the equation

0:34:230:34:27

so how do you make a boat that is going to operate better?

0:34:270:34:29

And I will use wind power, surface currents and the waves to actually

0:34:290:34:33

navigate up the wind to capture the oil that is drifting down the wind.

0:34:330:34:37

Cesar's plan was to create a fleet of unmanned remote-controlled

0:34:380:34:43

sailing drones that could cover the sea surface more effectively.

0:34:430:34:47

Each boat would tow behind it a huge absorbent sponge

0:34:480:34:52

that would get heavier and heavier as it soaked up the oil.

0:34:520:34:56

So how did you go about designing a sailing vessel

0:34:590:35:01

that is able to tow something like that upwind?

0:35:010:35:04

So imagine this is a conventional sail boat

0:35:040:35:07

and a conventional sail boat has a rudder at the back.

0:35:070:35:11

So imagine you have something very, very long behind,

0:35:110:35:14

it's going to be really difficult and very ineffective to move that part here.

0:35:140:35:17

You can't manoeuvre the boat?

0:35:170:35:19

So what we did is that we took the rudder that's normally here

0:35:190:35:22

at the back and brought it at the front, right here,

0:35:220:35:25

and so you can imagine, if you have something long and heavy behind,

0:35:250:35:28

you already have a lot more influence in controlling this part.

0:35:280:35:31

And then we kept adding a rudder, and at some point we were like,

0:35:310:35:34

what if we make the whole boat curve

0:35:340:35:36

and the whole boat becomes the organ of control, so we have more control

0:35:360:35:40

over something long and heavy, it would be a lot more.

0:35:400:35:43

So the whole hull is flexible, the entire thing?

0:35:430:35:46

-It resembles some kind of skeleton of a dinosaur or something.

-Yeah!

0:35:460:35:50

Cesar had a brilliant idea,

0:35:530:35:55

but neither the technical skills nor the hard cash to bring it to life.

0:35:550:35:59

So he did something which I think is pretty radical for an inventor.

0:35:590:36:04

He shared his idea on the internet,

0:36:040:36:07

opening it up to collaborators for free.

0:36:070:36:11

I started posting it on a website and some scientists

0:36:130:36:16

and engineers just started looking at this and thinking it has

0:36:160:36:18

a lot of potential and people were really excited about it.

0:36:180:36:21

Soon inventors from all around the world started to contribute

0:36:210:36:26

their ideas to the project, and many others began to donate money.

0:36:260:36:30

So we had 300 people give us ten, 15 dollars,

0:36:320:36:35

20, 100, and we collected more than 33,000.

0:36:350:36:39

With this funding, Cesar was able to set up a workshop

0:36:410:36:45

and he invited inventors from around the world to come and work with him.

0:36:450:36:50

I'm Tu Yang-Jo, I come from China.

0:36:500:36:53

I'm Logan Williams, I'm from the United States.

0:36:530:36:56

My name is Roberto, I am originally from El Salvador.

0:36:560:36:58

My name is Francois de la Taste, and I am from Paris, France.

0:36:580:37:01

My name is Molly Danielson, I'm from Portland, Oregon.

0:37:010:37:05

This free not-for-profit exchange of ideas through the internet

0:37:070:37:11

is known as open hardware.

0:37:110:37:14

Open hardware means that we can innovate a lot faster

0:37:170:37:19

because we are not limited to a small number of people

0:37:190:37:23

but the whole internet community is giving us feedback.

0:37:230:37:27

The only condition for those participating

0:37:270:37:30

is that they must credit other inventors' work

0:37:300:37:32

and use the information to further the project.

0:37:320:37:35

You're almost flipping the whole system on its side.

0:37:350:37:38

It's not about profit first, environmental near the end.

0:37:380:37:42

You're making the environment a priority,

0:37:420:37:44

-which means we all have to start thinking differently?

-Yep.

0:37:440:37:47

The conventional way is that a scientist or an inventor has an idea.

0:37:470:37:51

He goes to the office of patents and says, "OK, the idea is mine,

0:37:510:37:54

"and I'm going to talk to a manufacturer and together

0:37:540:37:57

"we're going to make a deal and we'll sell this as expensive as possible to people,"

0:37:570:38:01

and the thing is that this is really good for the manufacturer

0:38:010:38:04

and the inventor but not really good for the people.

0:38:040:38:07

Open hardware, open sourcing, crowd sourcing,

0:38:100:38:14

releasing intellectual property freely on the internet -

0:38:140:38:18

these are all part of a new culture of openness and sharing

0:38:180:38:22

that's re-shaping how and what we invent.

0:38:220:38:24

I think the biggest change

0:38:330:38:34

is the fact that things now happen worldwide.

0:38:340:38:38

You don't get the individual inventing things on his own.

0:38:380:38:42

It's a worldwide collaboration on almost everything.

0:38:420:38:46

The inventor today is a collaborator, a sharer.

0:38:460:38:49

Somebody who isn't selfish and protective about their ideas,

0:38:490:38:54

but wants to, er, throw them out there and see how they can be nurtured and grown by others.

0:38:540:39:01

Today there's a really interesting

0:39:010:39:03

tension going on between

0:39:030:39:05

the open source movement

0:39:050:39:06

and business, so on the one hand people having ideas

0:39:060:39:10

and wanting them to go out into the public and flourish,

0:39:100:39:13

and people to riff on them, I suppose, and then there's making money.

0:39:130:39:17

And there's a battle between these two worlds.

0:39:170:39:20

I love the idea of where an idea

0:39:200:39:21

can come forward, where it can be

0:39:210:39:23

shared, where there's no patents,

0:39:230:39:25

where there's no copyright and where it's for the common good

0:39:250:39:28

but underneath all that, it has to get delivered

0:39:280:39:31

and somewhere, somebody has to earn something

0:39:310:39:33

so it's a difficult balance but the concept is fantastic.

0:39:330:39:36

At the heart of the open source movement

0:39:380:39:40

is of course our ever-increasing connectivity.

0:39:400:39:44

Today 2.3 billion of us are online.

0:39:440:39:47

What the internet gives today is the chance for people

0:39:480:39:53

to collaborate very quickly, to come up with the idea,

0:39:530:39:56

the messaging to communicate the idea, and then

0:39:560:40:01

the distribution platform to share the idea really, really quickly.

0:40:010:40:05

It just makes such a difference

0:40:050:40:07

to be able to suddenly send an e-mail to somebody

0:40:070:40:10

that you've never met, never seen before, and ask them a question.

0:40:100:40:14

How do you do this?

0:40:140:40:16

And they know how, and I can get that back immediately.

0:40:160:40:19

I think that more than ever now, the internet has reached

0:40:190:40:23

a kind of mainstream so that it's more possible to connect

0:40:230:40:26

with more people in a more profound way than ever before,

0:40:260:40:28

and to create different products and services on a global scale.

0:40:280:40:32

If you take a look at the patents currently being filed,

0:40:400:40:43

you can get a very good sense of where the next generation

0:40:430:40:46

of inventions is coming from.

0:40:460:40:48

What's clear is that many inventors are concentrating on the area

0:40:480:40:53

of alternative energy,

0:40:530:40:55

joining the race to find a replacement for fossil fuels.

0:40:550:40:58

Tapping the sun's energy is sometimes seen as the holy grail

0:41:040:41:08

but it's not all about solar panels.

0:41:080:41:12

In the deserts of New Mexico,

0:41:140:41:16

one company is taking a different approach.

0:41:160:41:19

Michael Glacken is on his way to their first ever production plant...

0:41:210:41:25

..a showcase for a new way of harvesting energy from the sun.

0:41:280:41:32

Inside this plant,

0:41:500:41:51

they've harnessed the power of one of the world's oldest organisms.

0:41:510:41:55

So, welcome to south-eastern New Mexico and our new plant.

0:42:020:42:07

You guys are pretty lucky

0:42:070:42:08

because we've only been in operation now for less than 24 hours

0:42:080:42:12

so you'll get to see everything as it happens.

0:42:120:42:15

The company's founder is Noubar Afeyan.

0:42:220:42:25

He's a biologist who's spent his life looking for alternatives to fossil fuels.

0:42:290:42:33

His inspiration comes from nature,

0:42:350:42:38

and one of the most common micro-organisms on the planet -

0:42:380:42:41

called cyanobacteria.

0:42:410:42:43

This is a piece of soil, and of course to the eye

0:42:450:42:49

it just seems like dirt that you find

0:42:490:42:52

in daily life in a lot of places,

0:42:520:42:54

but in fact, if you were to take this soil and refine it

0:42:540:42:58

and isolate from it all of the life forms,

0:42:580:43:01

a substantial amount of the life forms in fact will be cyanobacteria.

0:43:010:43:05

And these organisms have the basic capability of using sunlight

0:43:050:43:12

and carbon dioxide to live, and to exclusively live on those nutrients.

0:43:120:43:17

Cyanobacteria have remained almost unchanged for 3.5 billion years.

0:43:210:43:27

They were the first organisms to evolve the process of photosynthesis

0:43:320:43:37

that we see in plants today,

0:43:370:43:38

converting sunlight and carbon dioxide into chemical energy.

0:43:380:43:42

But Noubar's plan was to genetically modify them

0:43:450:43:48

to take control of this process.

0:43:480:43:50

The heart of the technology was to take that organism

0:43:530:43:56

and to begin to engineer the capability of that organism

0:43:560:44:00

to take the carbon from carbon dioxide and convert it into a fuel molecule.

0:44:000:44:06

The fuel molecule he sought to produce was ethanol...

0:44:080:44:12

..a biofuel which is usually created

0:44:130:44:16

by fermenting food crops such as corn.

0:44:160:44:18

But making it from corn can divert land away from food production.

0:44:200:44:24

At his labs in Bedford, Massachusetts, his team began

0:44:280:44:32

to search for a way to genetically modify the cyanobacteria.

0:44:320:44:36

When we entered the field, the tools that are needed to manipulate

0:44:400:44:44

the genetic make-up of these organisms did not exist at all,

0:44:440:44:47

and so there was a lot of inventing to do to transform them.

0:44:470:44:50

After five years of research,

0:44:510:44:53

the team managed to introduce the right combination of genes

0:44:530:44:57

into the cyanobacteria so that they would produce ethanol.

0:44:570:45:01

It was a remarkable achievement.

0:45:040:45:06

But to make the process economically viable,

0:45:080:45:11

all of the bacteria's energy

0:45:110:45:13

would have to be channelled into producing the fuel.

0:45:130:45:16

To do that, the team had to switch off

0:45:160:45:19

what is the most basic function

0:45:190:45:21

of every living organism on the planet - reproduction.

0:45:210:45:25

And when you do that,

0:45:270:45:28

you'll see a lot more carbon goes to making the product,

0:45:280:45:32

and that allowed us to create a micro-scale, single-cell factory.

0:45:320:45:37

It's a factory that does a very precise chemical conversion.

0:45:370:45:40

Think of it as a micro-refinery that could convert carbon dioxide

0:45:400:45:45

and solar energy into a fuel molecule.

0:45:450:45:49

And so today in New Mexico,

0:45:510:45:54

this plant is about to start harvesting fuel

0:45:540:45:57

from genetically modified cyanobacteria for the very first time.

0:45:570:46:01

So all these tanks, all this technology, all these valves

0:46:080:46:11

have been designed and installed to do one thing

0:46:110:46:14

and that is to use trillions and trillions of bacteria

0:46:140:46:18

to make fuel from the sun.

0:46:180:46:20

The first stage of the process is to make enough bacteria to produce the fuel.

0:46:210:46:26

The green is actually the cells themselves.

0:46:310:46:35

And last night we introduced them to this system.

0:46:350:46:40

This is a large circulation unit, 4,000 litres,

0:46:400:46:44

so what we want to see them do right now is get greener and greener,

0:46:440:46:47

basically reproduce, make more cells,

0:46:470:46:50

and increase in mass by about tenfold.

0:46:500:46:54

It'll take just a few days to reach the right amount of cyanobacteria.

0:46:550:47:00

The next stage is to make them stop reproducing, and shift them entirely

0:47:030:47:07

towards producing fuel using just carbon dioxide and sunlight.

0:47:070:47:13

And inside this can is the product of all that research.

0:47:190:47:24

So this is it, 500ml of the world's very first ethanol fuel

0:47:260:47:32

made by genetically engineered bacteria.

0:47:320:47:35

Now there are still many technical challenges to overcome

0:47:350:47:39

but this is a bold attempt to make a renewable fuel

0:47:390:47:43

that has the potential to be greener than oil.

0:47:430:47:45

Now, whether you like the idea or not, the technology that

0:47:480:47:52

allows us to make another organism produce something it normally wouldn't,

0:47:520:47:56

that can be of such value to us, is an incredible invention.

0:47:560:48:00

What they're doing is effectively re-engineering nature for our benefit.

0:48:000:48:06

It's part of a growing and important field called synthetic biology.

0:48:060:48:11

So what nature has is billions of years of practice

0:48:130:48:17

to perfect amazing solutions,

0:48:170:48:19

and what inventors are trying to do today

0:48:190:48:23

is to compress those billions of years into a few months

0:48:230:48:26

that can bring around something really useful.

0:48:260:48:29

If I had a billion pounds,

0:48:290:48:30

I would invest it in synthetic biology companies

0:48:300:48:33

because that area is so exciting.

0:48:330:48:35

They're going to programme organisms to do everything from

0:48:350:48:38

clean up oil spills to create new fuels, new drugs.

0:48:380:48:43

It's going to be an entire platform of stuff.

0:48:430:48:46

I think we've always taken inspiration from nature

0:48:460:48:48

for the things that we've invented,

0:48:480:48:50

but the point is that we're understanding the natural world

0:48:500:48:53

so much more at the moment and every new breakthrough

0:48:530:48:56

at a fundamental level I think leads to new technologies.

0:48:560:48:59

Today, all over the world, we're seeing some incredibly complex

0:49:000:49:05

and beautiful bits of science driving innovation.

0:49:050:49:09

But even with all this increased collaboration

0:49:090:49:12

and globalisation spurring on invention,

0:49:120:49:15

the most important thing of all is still a simple idea.

0:49:150:49:19

Michael Pritchard is a British inventor who decided

0:49:220:49:25

to tackle a simple but devastating problem.

0:49:250:49:29

How do you get clean water in a disaster zone?

0:49:290:49:32

The crisis that spurred him on was the Asian tsunami of 2004.

0:49:330:49:38

The initial tragedy of the wave's destruction

0:49:410:49:43

rapidly turned into a greater human catastrophe,

0:49:430:49:47

as drinking water supplies became polluted,

0:49:470:49:49

spreading sickness, disease and death.

0:49:490:49:52

The thing that struck me most was watching the tsunami,

0:49:570:50:01

was that there was water everywhere.

0:50:010:50:03

They were surrounded by water, the thing for life,

0:50:030:50:06

and yet they couldn't drink it and all the wells had come up

0:50:060:50:09

and they were contaminated,

0:50:090:50:11

and I just...I don't know, it just touched a nerve.

0:50:110:50:14

It just made me angry.

0:50:140:50:16

And that was sort of my cue really.

0:50:160:50:18

We don't need to ship water,

0:50:180:50:20

we just need to make the water that's there safe to drink.

0:50:200:50:23

Michael began looking at the membranes that are used

0:50:240:50:27

in sewage plants to filter harmful pathogens out of water.

0:50:270:50:32

He wondered if these nano-scale meshes could be used in a portable bottle.

0:50:320:50:37

Was it fairly easy to get your hands on a mesh that had pores the right size?

0:50:390:50:43

No, I had to work with people in the membrane world

0:50:430:50:48

to transfer their technology, if you like,

0:50:480:50:51

into a portable device, which is the lifesaver bottle.

0:50:510:50:54

And if I break it down, I can show you its sort of constituent parts.

0:50:540:50:58

That's the first level of filtration,

0:50:580:51:00

that's kind of a sponge, and that will stop an elephant to a twig.

0:51:000:51:05

But the...the real clever bit, if you like, is in this filter here.

0:51:050:51:10

I don't know whether you can see inside there, but there's windings.

0:51:100:51:15

-Yes.

-There's actually... that's a hollow fibre membrane

0:51:150:51:19

so now, with a pump, I can build up the pressure that I need,

0:51:190:51:23

and that will force the water through the membranes,

0:51:230:51:27

leave the contamination on the dirty side

0:51:270:51:30

and just let the sterile clean water come up.

0:51:300:51:33

I suppose what remains to be seen is if it works,

0:51:330:51:35

-which is why I presume this tank of water is here?

-Yeah.

0:51:350:51:38

That looks fairly benign.

0:51:380:51:40

In the middle of a flood zone, your water doesn't look like this

0:51:400:51:44

so I've gone and got some bits and pieces to put in it

0:51:440:51:47

to try and recreate what's going to happen in a flood zone.

0:51:470:51:50

Bits and pieces, you say?

0:51:500:51:51

Bits and pieces, so let's start off with something pretty simple,

0:51:510:51:55

some detritus, some leaves, twigs, that sort of thing.

0:51:550:51:59

Nice organic matter, it's all good.

0:51:590:52:01

Nice organic matter, that's pretty fine.

0:52:010:52:03

But that's not bad enough.

0:52:030:52:05

So, I've gone and got some water from the pond.

0:52:050:52:08

I'm just going to put that in as well.

0:52:080:52:10

What kind of pond do you have?!

0:52:120:52:14

THEY LAUGH

0:52:140:52:16

But what happens in a disaster is, the water surges

0:52:160:52:19

and up come the drains, OK,

0:52:190:52:21

so you've got all sorts of stuff going on in the drains.

0:52:210:52:25

So, I've gone and got some run-off from a sewage plant

0:52:250:52:29

and I'm just going to pop that in there, as well.

0:52:290:52:32

So...

0:52:320:52:34

Toilet roll and everything!

0:52:340:52:36

Yes! The whole nine yards.

0:52:360:52:39

But what I've also gone and got,

0:52:390:52:42

is a little gift from my dog, Alfie.

0:52:420:52:46

HE LAUGHS

0:52:460:52:47

And it's genuine.

0:52:470:52:49

It looks very real!

0:52:490:52:50

OK, so just let's put that in there.

0:52:500:52:52

Oh, good grief.

0:52:520:52:54

People don't believe this stuff.

0:52:540:52:56

And you're going to drink it.

0:52:560:52:58

This is not a smile of happiness. I smile when I'm nervous!

0:52:580:53:01

This is not good.

0:53:010:53:03

So, now, when you look at that, that is more like the water

0:53:030:53:06

that you're going to be faced with in the middle of a disaster.

0:53:060:53:09

So, what we're going to do is,

0:53:090:53:11

we're going to scoop up a jug of this water.

0:53:110:53:15

And let's just stir that up a bit. OK, let's get some of that...

0:53:150:53:20

Oh, look. We know where that came from, don't we?

0:53:200:53:24

-Exactly.

-Those bigger bits.

0:53:240:53:25

All we're going to do is pop it in here

0:53:250:53:27

-and make it safe to drink.

-Mm-hm?

-OK?

0:53:270:53:30

So, we chuck it in here like that.

0:53:300:53:33

That's it. It just goes everywhere. OK?

0:53:330:53:37

Put the base on. Give it a few pumps.

0:53:390:53:42

OK?

0:53:440:53:46

And then...

0:53:460:53:48

-Are you ready?

-Yeah.

0:53:480:53:49

-Do you want to hold it?

-Sure.

-OK.

0:53:490:53:52

Get it in. There we go. That's it.

0:53:520:53:55

And that is clean, sterile drinking water.

0:53:560:54:00

I am going to just check for those little bits of...

0:54:010:54:05

Have a smell. Have a smell.

0:54:050:54:06

-OK?

-It smells perfectly fine.

-Have a taste.

0:54:080:54:10

-What's it taste of?

-Water. Clean water.

0:54:150:54:17

Because that's all it is. OK?

0:54:170:54:20

It's fantastic. It's just brilliant.

0:54:200:54:21

And that is sterile, clinically sterile.

0:54:210:54:23

This filtration system is now being used by thousands of people

0:54:290:54:33

all around the world.

0:54:330:54:34

It's being used in Haiti and Pakistan

0:54:340:54:37

in the wake of devastating earthquakes.

0:54:370:54:40

And, to me, it shows that having a bold vision and the drive

0:54:400:54:43

to implement it are sometimes the most important part of invention.

0:54:430:54:48

Small, dedicated teams of individuals can do

0:54:540:54:57

what was once thought only possible by governments.

0:54:570:55:00

We've seen some inspirational inventors.

0:55:000:55:03

Together, they and thousands of others like them

0:55:030:55:06

are helping to create tomorrow's world,

0:55:060:55:09

and I've been intrigued to see what makes these men and women tick.

0:55:090:55:13

I think the one attribute

0:55:150:55:17

that all scientists and engineers and innovators need is curiosity.

0:55:170:55:22

Being curious about the world, asking questions that no-one else has asked.

0:55:220:55:27

I think you'll probably find that all inventors have

0:55:270:55:30

kind of darting and volatile minds.

0:55:300:55:35

Not regularly proceeding from A to B to C.

0:55:350:55:39

I think that, if you want to be an inventor, have good ideas,

0:55:390:55:44

then you can't get away with not doing the hard work.

0:55:440:55:47

The more challenges we have in life, the more exciting life is.

0:55:470:55:50

That's what it's like to be a human being.

0:55:500:55:52

Some people like to sit on the sofa and do bugger all.

0:55:520:55:55

Most of us like to rise to the challenge.

0:55:550:55:57

Innovative people and great ideas

0:55:590:56:01

have always been at the heart of invention.

0:56:010:56:04

But, what I find fascinating is how, today,

0:56:040:56:07

these inventions become a reality in a very different way.

0:56:070:56:10

We've seen how scientific prizes are making a comeback.

0:56:150:56:18

The importance of collaboration across different fields.

0:56:210:56:24

But there will always be a place for blue-sky thinking.

0:56:260:56:30

How we're starting to re-engineer nature itself.

0:56:300:56:34

And how the internet is changing everything.

0:56:370:56:41

Pretty much anyone today, if you have an idea,

0:56:510:56:55

you can actually make it, you can make it happen

0:56:550:56:58

and you couldn't do that 10 years ago,

0:56:580:57:00

let alone 100 years ago.

0:57:000:57:02

As human beings, we are really pushing boundaries at the moment

0:57:030:57:06

and that's what we're here for, and that's why

0:57:060:57:09

I never worry about the future of the human race,

0:57:090:57:11

because I think we're totally capable

0:57:110:57:13

and have shown, historically,

0:57:130:57:14

that we're totally capable of solving problems.

0:57:140:57:17

I think we're on the cusp of being able to create more things

0:57:190:57:23

in more innovative ways than ever before in history.

0:57:230:57:26

The process of invention is becoming a global conversation

0:57:330:57:38

with many minds interacting, sharing ideas,

0:57:380:57:41

making the seemingly impossible possible.

0:57:410:57:45

And the speed at which this is all happening

0:57:450:57:47

means that these inventions are changing our world

0:57:470:57:49

more quickly than ever before.

0:57:490:57:52

It's an exciting time to be alive.
