-From around the globe, four young entrepreneurs chosen to compete in a contest to change the world.

-Education changes everything.

-There should be some technology that should be able to capture these gases.

-I actually like to solve problems.

-And this is really how you scale an innovation so that it can be constructed locally.

-Each has only three minutes to make their presentation before some of the world's most influential people at the Ashoka Staples Youth Social Entrepreneur competition in Tucson, Arizona.

-There's a lot of problems with the way solar energy is done these days.

-Just 180 seconds that will make or break their idea.

-How can we bridge this gap, and how can we use technology to create a supportive health education network?

-180 seconds to make the most important presentation of their lives.

And the prize?

The world.

-The winner of the Staples Ashoka Youth Social Entrepreneur competition is... -You didn't think we were actually going to tell you the winner now, did you?

-No matter where you live in the world, there are problems to be solved.

-Problems such as air pollution, lack of clean water, of health care and eduction.

-But the good news is there are people, both young and old, that are working on new ways to solve these old problems.

-These people are called social entrepreneurs, and rather than generating profit for profit's sake, they build sustainable ventures to help solve problems.

-And anyone can be an innovator; you don't need loads of cash or a big fancy office.

-Exactly.

There are resources all around you that you can use in new ways to help make a difference.

-All you need is an idea and the will to follow through.

-The civic group Ashoka is the world's largest organization of social entrepreneurs.

-Ashoka provides guidance, resources, and networking to social entrepreneurs to help make their visionary ideas a reality.

-Now Ashoka has teamed up with Staples to create a competition for young entrepreneurs that are using technology to help solve social problems.

-Entries were received from all over the world.

-Over 50 countries.

-And then reviewed by a panel of judges.

-Really smart judges.

-And of all of the entries, four finalists were chosen.

-Those four where then flown to Tucson, Arizona where they were given only three minutes to make a presentation before global leaders in technology.

-Three minutes-- I'd be terrified.

-I know, we're talking about pitching to companies like Microsoft, Twitter, Facebook, Google, and DreamWorks.

-So who were these four finalists?

-And what were their creations?

-Well, let's start with Karthik, a young man from Bangalore who used Facebook to save lives.

-Hi, my name is Eden Full.

I am 19 years old.

I am from Calgary, Alberta, Canada.

And I developed a project called the SunSaluter.

When I was growing up, My dad's an artist, and he'd bring home all of these magazines and pictures of people doing different things.

What really appealed to me was solar panels.

You know, to me at the time when I was like five or six that was pretty magical.

I didn't understand the science behind it, and it seemed really interesting to me.

For the next couple of years, I'd enter these science fairs and I started to get really frustrated.

You know, I wasn't getting enough solar power out of these panels and so I started looking into how can you make a solar panel more efficient.

The way solar panels work now is they're really inefficient.

This is because they're not pointed at the sun.

This means that when it's not perpendicular to the sun it's not hitting the surface of the solar panel at exactly the angle you need to really maximize the number of electrons.

By going and pointing the solar panel at the sun you improve its efficiency by up to 40 percent.

You're getting enough electricity and every last drop of electricity out of that solar panel as you can, at every point during the day.

What I want to do is try to make it cheaper for you to rotate individual panels, or smaller sets of panels, on your roof, in your backyard, so that people who are using solar panels in their house or in a village will be able to use them in an optimized way.

Solar panels as they are right now are very expensive when you want to point them at the sun.

They use these expensive motors, which cost tens of thousands of dollars.

They're only viable when you're using them on 65,000 panels in the middle of Arizona.

These motors, not only are they expensive, but they're really hard to maintain.

The principle behind the SunSaluter is that it uses a series of bimetallic coils.

So this means having two types of metal that are welded together.

And so you have steel and aluminum, and they're blast welded so that when they're connected together, because these two types of metals are different, one will expand at a different rate than the other when it's heated up.

And so that means that when one is heating up more than the other it'll want to bend in one direction.

And so when it bends in one direction based on the ambient temperature change, it can cause a rotation of the solar panel.

At different times during the day, when these bimetallic coils will displace at different times, then that causes your solar panel to want to rotate to follow the sun like a sunflower.

I'm not using more electricity to rotate the solar panel to get electricity.

That is really counterintuitive and frustrating and doesn't make any sense to me.

What I want to do is be able to incorporate harnessing that thermal component of solar energy while being able to collect as much light as possible in order to stimulate the electrons.

Last summer, I had a chance to deploy two pilot projects for the SunSaluter in Kenya.

And it really helped me to sort of understand how can I make the technology be more durable, do they actually have access to bamboo, where can they get recycled metal.

Like, these were all things that you could only understand once you actually go on the ground.

Each of these villages has about 500 people.

A lot of them have bought cell phones and solar lanterns, but they don't have a consistent way to charge them.

I remember the first week I was there I was just going to do an assessment.

And there was this woman that I met there, and she has three kids.

She's a wife, she cooks and she cleans and she's doing everything that she can for her family, and she showed me these three solar lanterns she has.

She was telling me how the solar panel that came with these lanterns, it was enough to charge two of them, but there wasn't enough to charge a third lantern.

And I thought, "Well, this problem can be easily solved.

I'm going to go back into town, make sure I buy the right materials, and I will build you a SunSaluter."

I came back like, a week and a half later maybe.

And I asked around, where is she?

And a lot of the villagers were telling me she got trampled by a buffalo.

She wandered into the dark, right, to collect firewood.

It really struck me that if she had enough electricity to be charging that solar lantern the whole situation would have been avoided.

Part of the reason that I am still working on this technology is I would really like to do my part so that something like this doesn't happen.

When I was in Kenya, I didn't really know what I was doing.

So this is how I got in contact with Darrel DeBoer.

He's an architect who works a lot with sustainable materials and one of his passions is in bamboo.

-I've been working with alternative materials, which are actually the ones that people have been using for millions of years.

Earth, straw, very simple materials, things that aren't owned by companies, that are the kinds of things that three-quarters of the world lives in.

-He has a lot of insight into what kind of materials should I be using, and how should I be joining the bamboo together.

And these are all really important skills that I'm still learning.

He's definitely an expert in the area.

-I think if she succeeds it allows for an incredible increase in the efficiency of what we're trying to do right now.

Being able to use energy much more efficiently and effectively is really the answer.

I mean, we're running out of resources.

-How do we make the SunSaluter something that's viable in many different locations across the world?

Really, the most important thing is designing a technology that can be used in as many different places as possible.

That's how you really get something to scale.

I really think of myself as an inventor, an ideas person, someone who comes up with different ideas that, you know, have a social good and a social impact on the world.

And I really want to do my part to really make sure that these ideas are going to scale in the way that they need to in order to, get them out to as many people as possible.

I believe that passion plus hard work equals success.

If you like something, you care about it, and you're willing to work for it, you can make anything happen.

-My name is Vineet Singal.

I'm a senior at Stanford University, and I'm the co-founder and Executive Director of Anjna Patient Education.

Ever since I can remember I've been overweight.

And that problem escalated as I moved from India to Saudi Arabia to New Zealand.

In New Zealand, I actually remember being heavily bullied because of my condition, delayed puberty.

And so, I stuck out, you know, a short, chubby Indian boy with glasses in a very homogeneous white environment.

And one time I remember these three bullies sitting in front of English class, and I was coming late to class.

This one boy screamed in front of the entire class, "Hey Vineet, show us your cleavage."

This was an example of the kind of experiences that I had that led to me having all sorts of mental health problems, and all sorts of self esteem and self confidence issues.

I realized that this was a problem that not just I had.

This was a problem common to many people around the world.

My parents who had always been physicians, who had always been learning about different kinds of medical issues, and always had instilled in me a deep desire to become a physician... That desire was actually cemented when I took time off from school and worked full time for this free clinic in Galveston, Texas.

The clinic, I started a health education program which specifically utilized my experience overcoming obesity and overcoming diabetes and overcoming clinical depression.

And this was a very simple thing, but it eventually led to a lot of good things down the line.

Especially when I saw patients coming back and... you know, on a monthly, bi-monthly basis, having made extremely significant behavioral changes.

-Our mission at Clinic by the Bay is to provide preventative and primary care.

Critical to that mission is having accessible, user friendly health education materials.

-So Anjna Patient Education is a Stanford based non-profit organization that aims to institute quality health education programs, utilizing technology and free clinics.

Our first project is the Health Education Database Project, where we provide free clinics with access to health education materials that are visually appealing, textually minimal, and available in multiple languages designed to be culturally appropriate.

It's the first ever health education database developed specifically with free clinics in mind.

And we have done this with the help of our volunteers and our faculty mentors.

-Can you click on that so we can see that?

We use Anjna's database.

It's a health education database.

They create information that is accessible, easy to use, simple, visually pleasing, and very user friendly.

It's also in multiple languages, which... here at Clinic by the Bay most of the patients that we serve don't speak English.

It's not their first language.

It's usually Spanish or Cantonese.

-Our second project is called Project Not Alone, which enables clinics to utilize tablet computers for the purpose of reaching out to socioeconomically disadvantaged populations.

Especially in certain free clinics when people are waiting for as much as three hours, we believe that the time that is spent reading magazines can be utilized for positive health education.

Our third project deals with text messaging.

Everyone has a cell phone, and we want to utilize that phenomenon to... in order to reach out to underserved populations, giving them reminders to take their medication, make future appointments, or just simply advice on leading a healthy lifestyle.

-It's been a perfect match, and a great partnership.

It's had an incredible impact on our volunteers to have information that they can easily share with the patien... our patients, who then learn to take better care of themselves, eat better, exercise more, and ultimately live healthier lives.

-So we have, you know, different projects that are going on... We started out with a team of two people.

And we realized the importance of targeting free clinics, especially with something as serious as underemphasized as health education was concerned.

We built a team.

We got friends together, we got volunteers, we got people to help out, and we've grown to a team of over 200 people, which constitute mostly undergraduates and graduate students from Stanford and Berkeley, as well as students from 14 college campuses around the country.

This is really what we see as the central focus of the organization going forward.

The organization's motto is "Design to be Sustainable".

Our goal is not to provide the health education volunteers, but rather empower and enable free clinics to be able to do the health education themselves, because we know that they are the ones that know the most about their own specific clinics.

-The reality is there are a lot of health education materials and information out there for all of us, on the Internet, in books, in brochures.

But what Anjna has done is created materials that are easy to use, user friendly, visually pleasing.

So this is a critical opportunity for us, I think particularly in this country, to improve health outcomes by using health technology.

-I think that technology has huge potentials in health care.

But I also think that because the health care industry's always behind the technology industry there needs to be some specific efforts made to bridge that gap.

And this is where Anjna Patient Education is helping do that.

If you have a burning issue, you have a burning problem, you can make a change.

You can make a difference.

It just takes you, a lot of enthusiasm, a lot of passion, and a lot of perseverance, and a few friends to help you.

You can do it.

-So there you have it-- the four finalists for the Staples Youth Social Entrepreneur competition.

-And as finalists, each will have just three minutes to pitch their ideas to bigwigs at the Techonomy Conference in Tucson, Arizona.

-The conference is held once a year to share new technology that could change the world and change how we think of our social problems.

-Techonomy is a conference that aims to explore and explain why technology is becoming so central to our lives, and what that means for the future.

The idea is that especially leaders and especially leaders in government and really senior people in business and non-profit education, wherever, for the most part don't really see how big the changes are that are coming.

No matter what you do, no matter what you think about, here is why you should be thinking even more about technology's impact on that than you already do.

-I'm actually really excited about it.

There's going to be this opportunity to meet so many different people who are working, you know, at the intersection of technology and economy, which is what the conference is all about.

-I realize this was such a great opportunity for me to showcase my ideas and showcase my organization on a more national stage.

-Well, the Techonomy Conference is really aimed to educate everybody about why technology is becoming more important in every single thing that people do.

-As an aspiring social entrepreneur, it will be really important for me to actually talk to all of these people who have that business experience and that real world experience that I don't have yet, and that I'm still looking for.

I really like to think of myself as an aspiring social entrepreneur.

Bill Drayton, the founder of Ashoka, came up with the concept of social entrepreneurship back in the '80s, and it's really about promoting business ideas that can be sustainable and really promoting the use of scaleable technologies.

-Our essential goal is how do we help society become an everyone a change maker society?

So young people practicing being change makers is critical for that.

-At this conference, business leaders will learn of innovative new ideas and how those ideas will impact our future.

-It's the perfect place to pitch an idea that could change the world.

-And the winner of this competition will win an around-the-world tour with Ashoka.

-Winning could mean taking their technology venture global.

-It's a good thing our finalists had a couple days to prepare.

-Yeah, because the rehearsals were a little rough.

-The first rehearsal we had was, for the most part, a pretty big disaster.

Partly because they were unorganized, they didn't really have everything down yet.

-Karthik is the one that's the most nervous.

Karthik has never talked in front of an audience before, and on Monday morning we're going to have close to 300 people, plus live streaming, and it's a huge stage with two screens.

He's nervous and I'm nervous for him.

He's working really hard.

-Karthik, he's also coming from India.

And dealing with giving a presentation to an English speaking crowd, we want to make sure that his Powerpoint isn't pushing him too much, that he can slow down a little bit and really emphasize what's on his slides and create a relationship with the audience.

And I think that's going to be a really hard thing for some of our international participants.

-You have 40 seconds to spare.

I mean, do you know how you want to end it?

Okay, if you feel comfortable, I mean... Karthik right now does not have an ending to his speech.

And we really need to work on that, because he needs to woo them.

He needs to hook them at the end.

Okay, do you have the remote?

-I don't... oh, here we go.

The upcoming conference is extremely exciting, but I'm still a little nervous about the pitch because I know it's only going to be three minutes, and I know I have so much to talk about and so much to say.

So condensing that into, like, three minutes is going to be a big challenge, and I'm a little nervous about that.

We identified that there was a lack of... there was a... -Vineet, he's looking really good.

You know, he had a lot of slides up there, but he really has a very strong personal story with why he's doing what he does.

And I think that will bode really well with some of the participants and some of the audience gatherers as well.

We just need to work with him to pick out what he really wants to emphasize because he was a little over.

He's about halfway through his presentation when he hit the first three minute mark.

-And... yeah, I'm out of time.

Is it okay if I keep going?

-Are you over three minutes?

-Yeah.

No, I think you're going to get cut off.

-Okay.

-And you were only halfway.

-Yeah.

-Tonight we're just going to boil down what slides he actually wants to show, and make sure that he feels comfortable with the presentation he's making.

We're just here to help.

We don't want to change their presentations.

We want them to feel comfortable with what they're doing.

After all, this is their idea and, you know, we're here to help them.

-So that's how you want to do it.

-Yeah, you were only eight seconds over, so that's good.

-So we'll get to practice later today, too.

-I am nervous.

I think it's a good thing, it keeps me on my toes.

I don't want to go into anything knowing exactly how it's going to happen.

I feel like it's important for me to be prepared for the unexpected.

And basically...

I can't remember the words.

-Eden is just, you know, she... she definitely looks much younger than she is, but once she starts speaking about her passions and her idea she comes across very professional.

There's a lot of potential for this technology to scale.

-She is definitely very serious.

She puts a lot of effort into her presentations.

-Okay, do we want to try running through her again?

Or do we want to go through everybody once and then... -Do we need to run through it again?

-She will be the one that will try to do the presentation over and over again, with a timer, with a clicker, to make sure she's on her three minutes and it's the best it can possibly be.

-Vivek is very different from everyone else.

His style is very much, "I go up on stage, I say what I say, and it's going to come out great."

Vivek is a visionary.

We did his presentation a couple times during rehearsal and he had all these slides, which he totally forgot to click.

That was good.

You forgot all of your slides.

So you know, that's okay.

Maybe we decide not to do any slides or maybe we just do two.

-We really need to work on how he is articulating his message.

-So this is his first time coming to the United States and giving a speech to an English-speaking crowd.

That's not his native tongue, so we're going to have to work with him to really consolidate his message, to slow him down and to make sure that the proper slides and videos are in place to make sure his message is known.

-Okay, all right?

Let's do it one more time.

-What he's doing is truly amazing, and we want the audience to think that, but they're not going to be able to think that if he's really rushed, if he's really nervous and going a million miles an hour, which we all do when we're on the spot.

So we're going to work with him over the next 24 hours and make sure that gets taken care of.

-He has a very complicated project.

It's very difficult to understand.

So he has to show it through slides and video and really speak slow, because he's also a really fast speaker.

So that's going to be his challenge.

-For Vivek's presentation?

-Yeah, so there's a Powerpoint.

Well I think the four finalists, you know, they're getting there.

Okay we've got to go now, so...

But I think the next 24 hours are going to be pretty critical in the way that they really prepare.

-With time running out on the stage, the contestants move to individual one on one sessions.

Now is the time to concentrate on message and delivery.

-All right, how are we feeling here?

That's just a lot of... you need to write that into one page.

-Yeah.

-Do you want to try it at least one time now with the new text?

-Okay, stop, stop, stop, stop.

You... you've said this story a million times.

-Yeah.

-The newspaper, this young girl that is suffering from thalassemia, a very rare disease where you need blood transfusions 25 times a month.

-Yeah.

-You know this!

I definitely have a few worries about the presentations.

You know, they're... you can definitely tell which ones have been working on this for a very long time and the ones that put it together at the very last minute.

But now that they're here, they're really going to have to focus to pulling things together.

-Can you believe that?

-Make the connection between the aunt and the society.

-They only get three minutes.

So three minutes is a very very short time for slides, for introducing yourself, and really, you know, telling the entire audience what it is they're doing.

-We only give them three minutes because we think it's an important exercise to teach youth how to boil down their message.

To be an entrepreneur you need to have your elevator pitch down.

You need to be able to get your point across quickly, and you need to capture them, you need to hook them so that they'll take that next step in either helping you out with your venture or connecting you to someone that will.

And so even though three minutes is not a lot of time, it's important that they understand how to condense their message to be effective in promoting their idea to other people.

-Slow.

-Okay, yeah.

-Whoo-hoo!

Okay, awesome.

I want you to do it actually one more time.

-Yeah?

-I liked the ending.

Here, you know what?

Repeat it.

"We only make it for one dollar."

-Yeah.

-Either you pause, "One dollar."

400 versus one.

And I keep telling you, this is awesome.

-I think it's always good to be a little nervous to keep you on your toes, but I think it's just a good experience to be here.

This is kind of the biggest scale event I've ever been to.

I think my work speaks for itself.

I've just got to tell them what it is, you know, why it's important, how they can help, what I'm working on now and, you know, what the future looks like.

-So one minute.

-I'm feeling...

I'm feeling pretty good.

I'm just rehearsing, so I'm finalizing my pitch, what I'm going to say, how's that going to relate to the Powerpoint, and then practicing.

So I mean,these are all the points I want to get across in the first minute.

These is like... lived around the world, battled these different challenges, and then the St. Vincent's stuff.

Romina, Josh, and the other participants have been extremely helpful.

They've actually helped me finalize my slides and then helping me do run-throughs, and helping us be more articulate, be more concise.

My name is Vineet Singal, and I want to talk about three things that have influenced my project.

The first one is that I've lived around the world, from India to New Zealand to Saudi Arabia to New York City, and now in the Bay Area in Stanford University.

The second... -How did the fact that you lived abroad influence you?

-Oh, empathy.

-Having... having lived through racism.

-And that's how your experience abroad should be.

To learn of empathy and the importance to understand where people are really coming from.

You have to be the taskmaster, because otherwise they'll just keep going and talking for ten minutes, and I want them to do the best that they can.

I mean, that was really our role.

It wasn't about one more than the other or helping them win the competition.

It was more about, "What can I do to help you give the best pitch you've ever given before?"

So if you have done this ten times, I'm going to help you do it better than the ten times.

If this is your first time doing this, I'm going to help you do the best you can for a first time pitch.

-Yeah, there's a lot to be done, and a lot to educate new participants in new surroundings.

And so it's fun for us because we get to lend our expertise and, you know, we've been in similar situations that they have in the past so we get to use the, you know, the mistakes or the nerves that we felt, and we're able to help comfort them in any way we can.

Help give them new ideas, new tips, new techniques to make their presentations better.

-Practice continues throughout the day, and no time is wasted.

All four contestants worked with little let-up to better craft their speeches-- cutting dialog, changing slides, smoothing rough spots, all in an effort to make the best possible presentation.

-You really get to understand this enormous potential that young people have to create change.

Whether it's, you know, change through technology, which is what they do, but also just simply creating change to better the world.

-I think there are a lot of other women and girls doing the kind of work I'm doing, and I'm hoping that I can just be, you know, a role model to some of those who are younger than me.

And I think having a lot of role models is especially important, and so I'll just do what I can.

-The pace is relentless, and as time goes on, the four work together sharing tips and offering support.

They may be competitors, but working together in such an intense situation creates fast friends.

-I think there was a turning point late at night where everyone just crashed.

Okay, each person gets two.

-Two, okay.

-So we just decided to go to dinner, play some games and, you know, do a little bit of practice in the late evening, but that was about it.

-It all depends upon how tomorrow pans out, but I think that whatever happens will happen.

-Dawn breaks over the Arizona desert.

It's the morning of the show and Karthik has been awake practicing since 1:00 AM.

-How are you?

-Best of luck, I'm doing well.

-Thank you so much.

-Big day today.

You going to go get them?

-One by one the contestants arrive in the hotel lobby.

Each has a case of the jitters, although you wouldn't know it from Karthik.

-I will personally come and drag you off stage.

-Eden, Karthik, Veneet, and Vivek have traveled from the corners of the globe to an event that could change their lives.

In a few hours they'll know who will be named the winner.

They're more than competitors-- they're now friends, thrown together in this once in a lifetime competition.

-15 minutes to showtime and the audience filters in-- business and tech leaders who will decide the winner.

The contestants use this time for one last rehearsal, even if they only thing listening is the coffee maker.

-And three, it doesn't require any man power to be updated... -They put all the effort.

I was sharing a room with Eden and I'm pretty sure she was up until 3:00 AM last night.

I also know Karthik woke up at 1:00 AM.

Vineet I think was up at 5:00 AM.

So they kept practicing over and over again.

-Everyone tries to push back their nerves on the anxious walk to the stage.

-Ladies and gentlemen, please take your seats.

Our program beings in one minute.

-And then, before you know it, it's showtime.

-Good morning everyone.

You're about to meet four extraordinary and extraordinarily young innovators, who are winners, and now finalists, in the Staples Ashoka Youth Social Entrepreneur competition.

The four finalists are going to deliver their pitches this morning and you're going to chose the grand prize winner, who's going to be awarded an around-the-world learning tour with Ashoka.

Pay close attention to their presentations, because you will have to vote immediately after they finish.

And now, the candidates.

Eden Full is 19 years old, she's from Canada, and she's the founder of Roseicollis Technologies.

Karthik Naralasetty is 22, he's from India.

He's the founder of Socialblood.com.

Vineet Singal, 21, from the U.S. His company is Anjna Patient Education.

And Vivek Nair is 23 years old, he's from Singapore, and he founded Damascus Fortune.

Each candidate has exactly three minutes to make his or her pitch to you.

Contestants, be warned-- we will unceremoniously yank you from the stage if you go over your time limit.

Without further ado, Eden, take it away.

-Hi, everyone.

My name is Eden Full and I'm the founder of Roseicollis Technologies.

I've developed a technology called the SunSaluter.

-Education changes everything.

I have spent 18 years of my life living around the world in countries like India, Saudi Arabia, New Zealand, and New York City.

And there have been two things that have been common throughout my life.

The first is that I've always been different.

The second is that I've always been overweight.

-What is the SunSaluter?

Well, it's a low-cost non-electrical rotator for your solar panel to generate up to 40 percent more electricity from each individual panel at every point during the day.

-It's not that information doesn't exist, but it's not presented in a way that is accessible to underserved individuals and readily available to them.

-I thought of a way to rotate the solar panel, and I had a chance to test this out in Kenya last year.

And I built the whole prototype for just about ten dollars, on the ground, right there.

-So we have iPad and Android applications that are interactive.

They use animations and game dynamics to make the patient the narrator of his or her own story.

-Currently though, 80 percent of these solar panels don't rotate.

And I really believe that with the SunSaluter we can do better than this.

(timer sounding) -Karthik, I hate to unceremoniously interrupt your talk but... -And if SunSaluters are installed on 15 percent of solar panels by 2020 all of Tucson will be carbon neutral.

Thank you.

-We have reached almost 5,000 patients monthly and collectively over ten clinics, and we plan to reach over 100,000 patients by 2015, with 40 partner clinics.

-Sorry to interrupt.

-Thank you so much.

-Thank you.

-Now it comes down to voting.

The delegates vote by texting in their choice.

-The votes will then be tallied and the result will be announced at a big dinner later.

-They all did great, but there can only be one winner.

-Yeah, I wonder how they felt about their presentations.

-You know, I wonder what's for dinner.

-Pretty relieved it's done, it's over.

Three minutes flew by like that.

-I'm really glad I got to go first, because if I had to go last or something I would have just been totally freaked out.

I'm pretty happy with how I did, I think.

You know, I finished right at the three minute mark when Adam said thanks, so that was kind of crazy.

-And it was... it was just a great experience.

-Man, from rehearsal to presentation it was amazing.

I think the kids really honed in on what they wanted to say and made their points so... they articulated it so well.

-Oh, I feel relief.

I'm like, "Thank God this is over-- we can enjoy the rest of the conference."

But I'm really happy.

They all did amazing.

-All the hard work they put in for the last 48 hours here in Tucson, it was just really remarkable.

These youth competitors really put everything they had on the line and they came through in the end.

-It was a humbling experience to watch them.

That's the first thing I was thinking.

-I really was very very impressed with the young woman who was working on the solar panel issue.

She was just very inspiring.

- I have two personal favorites.

The first one was the solar rotation panels, and the other one was I believe the carbon fiber ones.

-I've already cast my vote and I'm not at liberty to reveal what it is.

-Really, all four are winners for making it to the finals.

But this is a competition, and there's only one grand prize.

Do you have a favorite?

Is it Karthik, using Facebook to connect blood donors and their recipients?

-Or Eden, with the SunSaluter?

-Or Vineet, using patient education?

-Or Vivek, turning waste carbon into nanotubes?

-Let's see who won.

-This was really a wonderful experience to have these young people presenting their innovations this morning.

Regardless of who the final winner is, I think we all can agree that this is an amazing quartet.

And now, the winner of the Staples Ashoka Youth Social Entrepreneur ccmpetition is... Eden Full.

Congratulations, Eden.

Would you like to say something?

Please say a few words.

-I'm really honored to receive the prize.

And I think I will do my best to continue scaling the SunSaluter and really doing the best that I can with the opportunity I've been given.

And I'd also like to thank the other three, Karthik, Vivek, and Vineet.

You guys have been awesome to hang out with in the past couple days and an inspiration to me and, like, I really hope that we'll be able to work together in the future.

Thank you.

-Do you have an idea that will change your school, your neighborhood, even the world?

-Have you ever cared about something enough to really want to change it?

-Have you ever thought what would happen if you used everyday materials to make an impact?

-Maybe it's something that will save lives.

Or maybe it's something that will make everyday life a little bit better for everyone.

-Anyone can invent, anyone can start a project.

So why not send your idea to Ashoka's next competition?

And maybe next year you can be the one to get three minutes to change the world.

BOTH: See you, Biz Kid.

-If you have an idea and you think it can solve a big problem I would say go for it, do it.

And, you know, you have nothing but opportunities and possibilities ahead of you.

-We already won, you know?

It's not about the grand prize-- we already won.

We are doing different things, right?

One is doing a 100 meters running, and one is doing swimming, and one is doing long jump, right?

It's very different things, and we're all winners.

-We have already have won, okay?

And we all got this big opportunity to come over here and, you know, it's... that message is always very big for me.

So I'm already happy.

That's why you see me happy.

-I mean, all doing good things.

I think that Eden deserved it because she's doing some incredible work, and I'm really happy for her.

-This is going to be so exciting.

I think I'm going to learn so much from being able to travel and meet the Ashoka fellows.

I mean, I have to admit I was kind of daydreaming about it but I didn't actually think it'd happen.

So, you know, this is just... it's a great honor, and I'm thankful that people selected me, and I'll do my best to make them proud.
