Michael Pritchard: How to make filthy water drinkable

Prevoditelj: Jelena Horvat Recezent: Tilen Pigac - EFZG

Good morning everybody.

Dobro jutro svima.

I'd like to talk about a couple of things today.

Danas bih želio govoriti o nekoliko stvari.

The first thing is water.

Prva je voda.

Now I see you've all been enjoying the water

Vidim da ste svi uživali u vodi

that's been provided for you here at the conference,

koju ste dobili na konferenciji

over the past couple of days.

u posljednjih nekoliko dana.

And I'm sure you'll feel that it's from a safe source.

I siguran sam da ste uvjereni da je sa sigurnog izvora.

But what if it wasn't?

No što ako nije?

What if it was from a source like this?

Što ako je s izvora nalik ovom?

Then statistics would actually say

Prema statistikama

that half of you would now be suffering

polovica vas bi sada patila

with diarrhea.

od proljeva.

I talked a lot in the past about statistics,

U prošlosti sam mnogo govorio o statistikama

and the provision of safe drinking water for all.

i opskrbljivanju svih pitkom vodom.

But they just don't seem to get through.

Ali čini se da nisam uspio.

And I think I've worked out why.

I mislim da sam shvatio zašto.

It's because, using current thinking,

Stvar je u tome da s današnjim načinom razmišljanja

the scale of the problem

opseg problema

just seems too huge to contemplate solving.

jednostavno se čini prevelikim da bi se našlo rješenje.

So we just switch off:

Pa jednostavno odustajemo.

us, governments and aid agencies.

Mi, vlade i humanitarne udruge.

Well, today, I'd like to show you

Dobro, danas vam želim pokazati

that through thinking differently,

da je drugačijim načinom razmišljanja

the problem has been solved.

problem riješen.

By the way, since I've been speaking,

Usput, od početka ove prezentacije

another 13,000 people around the world

još 13.000 ljudi širom svijeta

are suffering now with diarrhea.

sada pati od proljeva.

And four children have just died.

I četiri djeteta su upravo umrla.

I invented Lifesaver bottle

Izumio sam Lifesaver bocu

because I got angry.

jer sam se razljutio.

I, like most of you, was sitting down, the day after Christmas in 2004,

I ja sam kao većina vas sjedio dan poslije Božića 2004.,

when I was watching the devastating news

i gledao katastrofalne vijesti o

of the Asian tsunami as it rolled in,

posljedicama azijskog tsunamija

playing out on TV.

na televiziji.

The days and weeks that followed,

U danima i tjednima koji su slijedili

people fleeing to the hills,

ljudi su bježali u brda

being forced to drink contaminated water

i bili su prisiljeni piti kontaminiranu vodu

or face death.

ili umrijeti.

That really stuck with me.

To me uistinu pogodilo.

Then, a few months later,

Tada, nekoliko mjeseci poslije

Hurricane Katrina slammed into the side of America.

uragan Katrina pogodio je Ameriku.

"Okay," I thought, "here's a First World country, let's see what they can do."

"O.K." pomislio sam, "to je zemlja Prvog svijeta, hajdemo vidjeti što oni mogu učiniti."

Day one: nothing.

Prvi dan: ništa.

Day two: nothing.

Drugi dan: ništa.

Do you know it took five days to get water to the Superdome?

Znate li da je trebalo pet dana da voda stigne do humanitarnog kampa?

People were shooting each other on the streets

Ljudi su pucali jedni na druge na ulicama

for TV sets and water.

zbog TV-a i vode.

That's when I decided I had to do something.

Tada sam odlučio da moram nešto učiniti.

Now I spent a lot of time in my garage, over the next weeks and months,

Proveo sam mnogo vremena u garaži u tjednima i mjesecima što su uslijedili.

and also in my kitchen -- much to the dismay of my wife. (Laughter)

I također u kuhinji, na veliku žalost moje supruge.

However, after a few failed prototypes,

Međutim, nakon nekoliko neuspješnih prototipa,

I finally came up with this, the Lifesaver bottle.

konačno sam otkrio ovo, Lifesaver bocu.

Okay, now for the science bit.

O.K., sada znanstveni dio.

Before Lifesaver, the best hand filters were only capable

Prije Lifesaver boce najbolji ručni filteri mogli su

of filtering down to about 200 nanometers.

filtrirati do oko 200 nanometara.

The smallest bacteria is about 200 nanometers.

Najmanja bakterija je oko 200 nanometara.

So a 200-nanometer bacteria

Tako da će 200 nanometara velika bakterija

is going to get through a 200-nanometer hole.

proći kroz filter od 200 nanometara.

The smallest virus, on the other hand,

S druge strane, najmanji virus

is about 25 nanometers.

je veličine oko 25 nanometara.

So that's definitely going to get through those 200 nanometer holes.

Tako da će on definitivno proći kroz filter gustoće 200 nanometara.

Lifesaver pores are 15 nanometers.

Pore Lifesaver boce su 15 nanometara.

So nothing is getting through.

Tako da ništa kroz njih ne prolazi.

Okay, I'm going to give you a bit of a demonstration.

O.K., sada ću vam malo demonstrirati.

Would you like to see that?

Želite li to vidjeti?

I spent all the time setting this up, so I guess I should.

Proveo sam toliko vremena postavljajući ovo. Valjda bih trebao.

We're in the fine city of Oxford.

Mi smo u lijepom gradu Oxfordu.

So -- someone's done that up.

Dakle -- netko je ovo zašarafio.

Fine city of Oxford, so what I've done is I've gone

Ono što sam učinio u lijepom gradu Oxfordu je da sam otišao

and got some water from the River Cherwell,

i uzeo malo vode iz rijeke Cherwell

and the River Thames,

i rijeke Temze

that flow through here. And this is the water.

koje ondje teku. I ovo je ta voda.

But I got to thinking, you know,

No mislio sam, znate,

if we were in the middle of a flood zone

da smo usred poplavljenog područja

in Bangladesh, the water wouldn't look like this.

u Bangladešu voda ne bi izgledala ovako.

So I've gone and got some stuff to add into it.

Pa sam nabavio još neke stvari da dodam u vodu.

And this is from my pond.

Ovo je s mog ribnjaka.

(Sniffs) (Coughs) Have a smell of that, mister cameraman.

(Miriše) (Kašlje) Pomirišite ovo, gospodine kamerman.

Okay. (Laughs) Right.

O.K. (Smijeh) Tako je.

We're just going to pour that in there.

Sada ćemo uliti ovo ovamo.

Audience: Ugh!

Publika: Uh!

Michael Pritchard: Okay. We've got some runoff

Michael Pritchard: O.K. Imamo ovdje i otpadne vode

from a sewage plant farm.

iz kanalizacije.

So I'm just going to put that in there.

Tako ću i to uliti ovamo.

(Laughter)

(Smijeh)

Put that in there. There we go.

I ovo ćemo ubaciti. Evo ga.

(Laughter)

(Smijeh)

And some other bits and pieces, chuck that in there.

I neke druge dijelove i komadiće ćemo ubaciti.

And I've got a gift here from a friend of mine's rabbit.

Imam i dar mog prijatelja zeca.

So we're just going to put that in there as well.

Pa ćemo i to ubaciti.

(Laughter)

(Smijeh)

Okay. (Laughter) Now.

O.K. (Smijeh) Sada.

The Lifesaver bottle works really simply.

Lifesaver boca funkcionira zbilja jednostavno.

You just scoop the water up.

Samo zagrabite vodu.

Today I'm going to use a jug

Danas ću koristiti vrč

just to show you all. Let's get a bit of that poo in there.

da bih vam sve pokazao. Uzmimo malo ovog prljavog.

That's not dirty enough. Let's just stir that up a little bit.

to nije dovoljno prljavo. Malo ćemo to promiješati.

Okay, so I'm going to take this really filthy water,

O.K. uzet ću ovu stvarno prljavu vodu

and put it in here. Do you want a drink yet?

i stavit ću je ovdje. Želite li je sada popiti?

(Laughter)

(Smijeh)

Okay. There we go.

O.K. Idemo.

Replace the top.

Zamijenimo vrh.

Give it a few pumps. Okay?

Nekoliko puta napumpamo. O.K.?

That's all that's necessary.

I to je sve što je potrebno.

Now as soon as I pop the teat,

I sada čim skinem čep

sterile drinking water is going to come out.

sterilna, pitka voda će izići van.

I've got to be quick. Okay, ready?

Moram biti brz. O.K., spremni?

There we go. Mind the electrics.

Idemo. Pazite na elektriku.

That is safe, sterile drinking water.

To je sigurna, sterilna pitka voda.

(Applause)

(Pljesak)

Cheers.

Nazdravlje.

(Applause)

(Pljesak)

There you go Chris.

Izvoli, Chris.

(Applause)

(Pljesak)

What's it taste of?

Kakvog je okusa?

Chris Anderson: Delicious.

Chris Anderson: Ukusna.

Michael Pritchard: Okay.

Michael Pritchard: O.K.

Let's see Chris's program throughout the rest of the show. Okay?

Da vidimo kako će Chris biti do kraja prezentacije, O.K.?

(Laughter)

(Smijeh)

Okay. Lifesaver bottle is used by thousands of people around the world.

O.K. Lifesaver bocu koristi na tisuće ljudi širom svijeta.

It'll last for 6,000 liters.

Traje do 6.000 litara.

And when it's expired, using failsafe technology,

I kad istekne valjanost, koristeći sigurnosnu tehnologiju,

the system will shut off, protecting the user.

sistem će se zatvoriti kako bi zaštitio korisnika.

Pop the cartridge out. Pop a new one in.

Izvadite uložak. Stavite novi.

It's good for another 6,000 liters.

I bit će dobra za drugih 6.000 litara

So let's look at the applications.

Pa da vidimo mogućnosti primjene.

Traditionally, in a crisis, what do we do?

Uobičajeno, u krizi, što činimo?

We ship water.

Dovozimo vodu.

Then, after a few weeks, we set up camps.

Tada, nakon nekoliko tjedana postavimo kampove.

And people are forced to come into the camps to get their safe drinking water.

I ljudi bivaju prisiljeni dolaziti u kampove da bi dobili pitku vodu.

What happens when 20,000 people congregate in a camp?

Što se događa kada se 20.000 ljudi skupi u kampu?

Diseases spread. More resources are required.

Šire se bolesti. Potrebno je više izvora.

The problem just becomes self-perpetuating.

Problem se samo povećava.

But by thinking differently,

Ali s drugačijim načinom razmišljanja

and shipping these,

i dopremanjem ovih boca,

people can stay put.

ljudi mogu ostati gdje jesu.

They can make their own sterile drinking water,

Mogu sami sterilizirati vodu.

and start to get on with rebuilding their homes and their lives.

i početi obnavljati svoje domove i živote.

Now, it doesn't require a natural disaster

No, nije potrebna prirodna katastrofa

for this to work.

da bi ovo funkcioniralo.

Using the old thinking, of national infrastructure

Primjena starog načina razmišljanja, nacionalne infrastrukture

and pipe work, is too expensive.

i cjevovoda je preskupa.

When you run the numbers on a calculator,

Kada izračunate na kalkulator,

you run out of noughts.

nemate mjesta za nule.

So here is the "thinking different" bit.

Ali i ovdje možete razmišljati drugačije.

Instead of shipping water,

Umjesto da dopremate vodu

and using man-made processes to do it,

i koristite standardne procese da se to učini,

let's use Mother Nature. She's got a fantastic system.

hajde da iskoristimo Majku Prirodu. Ona ima fantastičan sistem.

She picks the water up from there,

Ona uzima vodu odande

desalinates it, for free, transports it over there,

desalinizira je besplatno i prenese je ovamo,

and dumps it onto the mountains, rivers, and streams.

i baci je na planine, rijeke, i potoke.

And where do people live? Near water.

A gdje ljudi žive? Blizu vode.

All we've go to do

Sve što trebamo učiniti

is make it sterile. How do we do that?

je sterilizirati je. A kako ćemo to učniti?

Well, we could use the Lifesaver bottle.

Pa mogli bismo koristiti Lifesaver bocu.

Or we could use one of these.

Ili bismo mogli koristiti jedan od ovih.

The same technology, in a jerry can.

Ista tehnologija u karnistru.

This will process 25,000 liters of water;

Može obraditi 25.000 litara vode.

that's good enough for a family of four,

A to je dovoljno četveročlanoj obitelji

for three years.

za tri godine.

And how much does it cost?

A koliko košta?

About half a cent a day to run.

Pola centa na dan.

Thank you.

Hvala vam.

(Applause)

(Pljesak)

So, by thinking differently, and processing water

Tako da drugačijim načinom razmišljanja, i procesiranjem vode

at the point of use,

na mjestu korištenja

mothers and children no longer have to walk four hours a day

majke i djeca ne moraju više hodati četiri sata dnevno

to collect their water.

da bi došli do vode.

They can get it from a source nearby.

Mogli bi je dobiti iz izvora u blizini.

So with just eight billion dollars,

Tako bismo sa samo osam milijardi dolara

we can hit the millennium goal's target

mogli dostići milenijski cilj

of halving the number of people

i prepoloviti broj ljudi

without access to safe drinking water.

koji nemaju pristup pitkoj vodi.

To put that into context,

Da to stavimo u kontekst,

The U.K. government spends about 12 billion pounds

britanska vlada potroši približno 12 milijardi funti

a year on foreign aid.

godišnje na inozemnu pomoć.

But why stop there?

Ali zašto tu stati?

With 20 billion dollars, everyone can have access to safe drinking water.

Sa 20 milijardi dolara svatko može imati pristup pitkoj vodi.

So the three-and-a-half billion people

I tri i pol milijardi ljudi

that suffer every year as a result,

koji zbog toga pate svake godine

and the two million kids that die every year,

i dva milijuna djece koja zbog toga umru svake godine

will live.

će živjeti.

Thank you.

Hvala vam.

(Applause)
