This week, solar powered cars, huge pipes, and lots and lots of green

:00:00.:00:15.

goo. That sounds like a good night out to me!

:00:16.:00:39.

Think power, think power stations, think power stations, these days

:00:40.:00:52.

think fossil fuels. That means emissions and huge amounts of carbon

:00:53.:00:57.

dioxide being pumped into the air. This is a miniature version of the

:00:58.:01:01.

new carbon capture facilities that we will start to see in power

:01:02.:01:06.

stations in the next few years. Their job is to capture as much CO2

:01:07.:01:15.

from waste emissions as possible. This facility at Imperial College

:01:16.:01:19.

London catches 500 tons of CO2 per year. A full-sized version will

:01:20.:01:25.

capture 1 million tons per year. This is... I am surrounded by

:01:26.:01:31.

science right here. This is part of the training for engineering

:01:32.:01:37.

students at Imperial, looking at alternative energy sources. As the

:01:38.:01:40.

largest solar research facility in the UK, much of what it does us try

:01:41.:01:44.

to improve the efficiency of solar cells. Doctor Alvarez is creating a

:01:45.:01:52.

new kind of solar cell that is two or three times more efficient than

:01:53.:01:56.

traditional silicon. Why aren't current solar cells very efficient?

:01:57.:02:04.

The problem is that silicon only picks up one part of the solar

:02:05.:02:09.

spectrum, and much of it is lost as heat. . You can put other cells in

:02:10.:02:19.

using different parts of the spectrum in, and that makes the

:02:20.:02:27.

overall efficiency much higher here is one of those so-called multi-

:02:28.:02:30.

junction solar cells. It may be tiny but it can cope with the sunlight

:02:31.:02:36.

focused from Lens 5002000 times bigger than itself. That is another

:02:37.:02:39.

thing traditional solar cells can't do. Last year, Australia held the

:02:40.:02:49.

world solar challenge. It is a race for cars powered entirely by the

:02:50.:02:52.

sun. Jonathan Blake was covering it for us and this is the story of what

:02:53.:02:58.

happened. Sleek, stealthy, futuristic

:02:59.:03:04.

machines. These solar cars will attempt to 3000 kilometre journey

:03:05.:03:07.

across Australia. I am with the first high school from Europe to

:03:08.:03:11.

take part in the challenge. From Darwin, through the outback to

:03:12.:03:16.

Adelaide. Their car looks a little different. It was built on a budget

:03:17.:03:22.

by teenagers from a college. It does stick out a bit but I think it is in

:03:23.:03:26.

a good way. It shows it is doable to do it as students with off-the-shelf

:03:27.:03:30.

items, just make something that does look great. After three years of

:03:31.:03:35.

work there is one final hurdle to clear before the team can race. A

:03:36.:03:39.

test lap to check the top speed, steering and brakes. It is a nervous

:03:40.:03:47.

wait for the team. The car passes and after a little helping hand, the

:03:48.:03:52.

team have a place on the grid. It is an amazing feeling, we are in the

:03:53.:03:59.

race! It is today the race, and previous winners from Delft

:04:00.:04:03.

University in the Netherlands are also preparing for the start. There

:04:04.:04:09.

are high-efficiency solar cells, a very aerodynamic car. It has about

:04:10.:04:14.

the air resistance of the side mirrors of a normal car, and it is

:04:15.:04:18.

very lightweight. We use the lightest materials we can find. We

:04:19.:04:24.

have carbon fibre and aerospace rated aluminium. The cars are making

:04:25.:04:30.

their way one by one across the start line and beginning the epic

:04:31.:04:34.

3000 kilometre journey across Australia. So excited, it is crazy.

:04:35.:04:44.

There is only one route between Darwin and Adelaide, but the team

:04:45.:04:47.

finds out it is still possible to get lost. About 50 metres into the

:04:48.:04:52.

race a policeman pulled us over because we are on the wrong road.

:04:53.:04:55.

They are not expecting solar vehicles on this road. It was a good

:04:56.:05:00.

start. Soon after the car gets moving again its words out of

:05:01.:05:06.

control. It is so scary because of all these cars going along at about

:05:07.:05:12.

100 kilometres per hour, we didn't get very far. We are going to try to

:05:13.:05:17.

get to the next control stop, we will have an opportunity to work on

:05:18.:05:24.

what went wrong on the road. But then, more drama. In the rear

:05:25.:05:27.

support car we can see smoke coming from the trailer. You are wrong

:05:28.:05:35.

fire! You are wrong fire! It has started rubbing against the metal

:05:36.:05:40.

frame causing it to smoke. I think we are going to take the car off,

:05:41.:05:44.

jack up the trailer, try to get the wheel off and go from there. After

:05:45.:05:50.

an eventful first, the team set up 400 kilometres down. You never

:05:51.:05:56.

assume things will go your way in a race, always something will come

:05:57.:06:00.

up. Definitely one thing we learned today. It is the morning of day two,

:06:01.:06:07.

and the team have had to make a difficult decision. After

:06:08.:06:10.

yesterday's near miss they are going to keep the car on the trailer and

:06:11.:06:15.

drive to Alice Springs. That is the halfway point, and there they will

:06:16.:06:18.

test the car and tried to figure out what went wrong. The team have

:06:19.:06:22.

decided it is not safe to put anyone in the drivers seat. It is

:06:23.:06:26.

disappointing, but we have to put safety first. It is the right thing

:06:27.:06:31.

to do. It means two days on the road and the team losing points for not

:06:32.:06:37.

driving the solar car. They can still stay in the race if they hit

:06:38.:06:43.

the checkpoints of time. -- runtime. In Alice Springs, the car gets to

:06:44.:06:47.

checkup and a test drive. After two days on the trailer, we are in Alice

:06:48.:06:51.

Springs, halfway, and the team have had a chance to regroup. It looks

:06:52.:06:56.

like it will get back on the road. Although chuffed to be back on the

:06:57.:07:01.

road, there are one or two hazards to deal with. We have an incoming

:07:02.:07:08.

road train. Our first major roundabout, what the hell do we do?

:07:09.:07:15.

Incoming truck! Soon, the car has another problem. All of a sudden the

:07:16.:07:22.

current started going up very quickly. The speed started going

:07:23.:07:25.

down, and we thought it might pass but the car kept going up and be

:07:26.:07:31.

speed kept going down. We think the brakes are constantly slowing down

:07:32.:07:36.

while taking more power. It is back on the trailer and onto next

:07:37.:07:42.

campsite. The brakes are fixed and the car is back on the road. The

:07:43.:07:45.

team from Cambridge University who have worked closely with them pass

:07:46.:07:51.

them on the road. It was amazing, it was beautiful driving along here.

:07:52.:07:56.

The car was working very well and it is great to get some kilometres on

:07:57.:08:02.

their. How was your foot? My foot is killing me, stuck in the same place

:08:03.:08:07.

for quite a while. It is great to get this far. At least an hour or so

:08:08.:08:11.

on the road for the car today, which is a real achievement. They were

:08:12.:08:15.

hoping to swap drivers but there is a problem with the battery, so after

:08:16.:08:19.

some roadside repairs it is back on the trailer and hopefully some more

:08:20.:08:24.

miles on the road later today. At the next control stop to fix their

:08:25.:08:28.

latest problem, the team had to break the seal on the car's battery,

:08:29.:08:31.

which could mean they have to withdraw. There is a chance phone

:08:32.:08:36.

call to a senior race official. We have heard from mission control that

:08:37.:08:40.

we can finish the race having done fix that we are going to do now. The

:08:41.:08:46.

car is taken off the trailer one final time despite all the problems

:08:47.:08:50.

the team has faced, and it is in one piece, ready to drive the final few

:08:51.:08:54.

kilometres through the city to the finish line. Congratulations! Well

:08:55.:09:06.

done, you made it. That is 3000 kilometres down for the team, so big

:09:07.:09:11.

celebrations tonight, and it will be great to see them come through the

:09:12.:09:15.

finish line with the car. It is a good feeling to have all the crowd

:09:16.:09:19.

here cheering. It was so good, everyone was cheering. We are so

:09:20.:09:25.

happy we have finished! A great effort for the students, who came

:09:26.:09:32.

sixth in their class. The overall winners were the Delft University

:09:33.:09:37.

team in the Netherlands, completing in just under 38 hours, and only

:09:38.:09:43.

eight minutes ahead of second place. Welcome to the week in technology.

:09:44.:09:48.

Let's start with something for science fiction fans, which includes

:09:49.:09:53.

me. Researchers have created a tractor beam made of sound, using

:09:54.:09:58.

speakers. It can successfully track, move and twist a small object.

:09:59.:10:02.

Instead of holding spaceships, research is expected to be used for

:10:03.:10:05.

smaller scale jobs like microsurgery. It is also the week

:10:06.:10:11.

that Apple announced more profits, Wall Street failed to be impressed

:10:12.:10:20.

by Twitter's meagre 4 million new users, and Microsoft unveiled the

:10:21.:10:23.

tablets oblique it comes with its own handle. And for something rather

:10:24.:10:27.

lighter, would you write this into space? One space tourism country

:10:28.:10:32.

seem to think so. They have completed test flight for a

:10:33.:10:34.

passenger balloon. It was successful, which puts it on track

:10:35.:10:43.

for a 2040 launch. If you have a spare ?50,000 and don't mind riding

:10:44.:10:49.

20 miles up in a balloon. By a strange twist of fate we have a

:10:50.:10:52.

second balloon story this week, courtesy of Google. The balloon

:10:53.:10:59.

internet project is scaling up, with the company launching a massive ring

:11:00.:11:03.

of helium balloons 60,000 feet into the stratosphere to being the

:11:04.:11:06.

internet to people living under their path. -- deem. Just starting

:11:07.:11:18.

my own business venture... Now, contrary to what you may

:11:19.:11:22.

think, there are other ways to use the energy from the sun than just

:11:23.:11:27.

turning it into electricity. This is the solar hydrogen lab at the

:11:28.:11:34.

Imperial: -- Imperial College in London. They producing algae, which

:11:35.:11:40.

produces hydrogen, and that is the fuel. We talked last week about

:11:41.:11:45.

hydrogen's use as a renewable energy, able to fuel cars without

:11:46.:11:50.

harmful emissions. Up until now, producing it in large quantities has

:11:51.:11:56.

involved burning fossil fuels, which is not at all green. That is where

:11:57.:12:00.

this lab comes in. It is green, bright green. Step one, store the

:12:01.:12:06.

algae in one of these. Step two, grow it in one of these. Step three,

:12:07.:12:12.

cultivated in some tubes like this, and step four, you put them into one

:12:13.:12:17.

of these photo by a react as. That is where the magic happens. It is

:12:18.:12:23.

inside these custom contraptions that the algae is put into a harsher

:12:24.:12:26.

environment, causing them to produce hydrogen. Stressed algae. Problem is

:12:27.:12:34.

it also kills the algae. Ordinarily, you would have to stop this process

:12:35.:12:38.

every so often to get rid of the dead plant matter and feed in new

:12:39.:12:42.

algae. The breakthrough research here is that scientists have managed

:12:43.:12:46.

to make that an ongoing process. They can replace the dead algae with

:12:47.:12:51.

living algae at the correct rate without stopping anything, and

:12:52.:12:54.

keeping the mini factory producing hydrogen for over a month. Batch

:12:55.:13:00.

system, you grow it, you make hydrogen, then it stops and you

:13:01.:13:04.

start from the beginning. In the continuous system you can use

:13:05.:13:09.

hydrogen all the time. The larger version of this test system can

:13:10.:13:14.

produce four litres of hydrogen each hour, which is six times as

:13:15.:13:19.

effective as a batch method. But really, even that is just a drop in

:13:20.:13:23.

the ocean. If you want to use hydrogen as a fuel, these have to be

:13:24.:13:31.

going for thousands of litres. When the sun goes down, these go to

:13:32.:13:35.

sleep, but as we all know that is also when the fun really starts. A

:13:36.:13:39.

couple of weeks ago we showed you a new camera that can shoot

:13:40.:13:46.

exceptionally good pictures in the dark. There seems to be a battle

:13:47.:13:49.

between manufacturers at the moment to create cameras that can do that.

:13:50.:13:55.

We asked our online camera guru to check-out Sony's latest lowlights

:13:56.:13:56.

offer. For 17 years I have worked as a

:13:57.:14:09.

cameraman. For the last ten years I have been a freelance filmmaker. I

:14:10.:14:13.

worked with George Lucas on his last film. Today I want to talk about

:14:14.:14:21.

cameras in low light. Night. -- Nice.

:14:22.:14:25.

As the light goes down and the winter nights come to us it is time

:14:26.:14:35.

to switch cameras. This is the A7S2. You can buy this on high-street. The

:14:36.:14:40.

image quality from this is to good, there is nothing stopping it being

:14:41.:14:49.

used in a cinema. -- so good. In the film days used to bias on that was a

:14:50.:15:01.

ISO. You would holiday in England. -- buy film. If it was dark and you

:15:02.:15:05.

would have a higher number. Digital is different. You can get the ISO

:15:06.:15:13.

you want in your camera. This is going to get darker and starker. You

:15:14.:15:19.

need higher numbers to compensate. -- darker. That is dark. Let me push

:15:20.:15:28.

the ISO up to 10,000. On my camera that looks like daylight. You get to

:15:29.:15:42.

a point where... Right now, it certainly sees more than my eye can

:15:43.:15:47.

be. I cannot see this lady's face with my eyes but this camera can. --

:15:48.:15:55.

can see. When I first got it I went down to Brighton beach and was

:15:56.:15:58.

amazed at how much I could see. I was seeing things I wasn't supposed

:15:59.:16:03.

to see with couples. I felt embarrassed and pointed the camera

:16:04.:16:09.

away. So, for me, the biggest benefits of a camera that I can

:16:10.:16:17.

shoot comfortably at 60,000 ISO is where I can go into where light is

:16:18.:16:24.

low and I can see better than I can with my eyes. This is the max I can

:16:25.:16:34.

see. 490,000. I don't think I would ever shoot at 400,000. Then again,

:16:35.:16:37.

five years ago, I said the same about 1600. By far, the hardest

:16:38.:16:44.

thing about shooting in lowlight situations... My eyes cannot keep up

:16:45.:16:50.

with the camera. I have trouble seeing the dots on the lens to get

:16:51.:17:00.

them in the right place. Well, it has got to that point of the year

:17:01.:17:04.

where so many blockbuster videogames are about to be released. We are

:17:05.:17:12.

testing the first one, Halo five. The Master Chief is back and this

:17:13.:17:16.

time he has brought his mates along for the ride. An Xbox exclusive,

:17:17.:17:23.

they proved that first person shooters can work on consoles by

:17:24.:17:27.

blending a grand space opera with incredible dialogue... If this all

:17:28.:17:35.

goes sideways... I understand... And shooting. Lots and lots of shooting.

:17:36.:17:43.

Baby came the yardstick by which all sci-fi shooters are now measured. --

:17:44.:17:51.

They became the. Their missions are now carried out by two different

:17:52.:17:58.

teams of Spartan super soldiers. The first team is led by Master Chief.

:17:59.:18:07.

Just like John Paul Van Damme, he has gone AWOL. The second team is

:18:08.:18:16.

led by Spartan Loch, their job is simple, track down the Chief. Being

:18:17.:18:23.

part of a team changes up single player. Other teammates can be given

:18:24.:18:29.

instructions or orders. Mark that turret. It can be fun, though it

:18:30.:18:36.

does lead to becoming a bit of a bossy boots. Routine, take that

:18:37.:18:41.

turret. It means you can approach tactical problems in different

:18:42.:18:46.

ways. -- Blue team. You can also have other humans playing with you

:18:47.:18:55.

via Xbox Live. There is a new big bad. I am the board. If by talk, you

:18:56.:19:01.

mean shoot everything that moves while hurling plasma grenades, well,

:19:02.:19:10.

you are in for it. There is a new multiplayer mode. It is called

:19:11.:19:16.

warzone, it allows 25 players to go out into huge maps while try to

:19:17.:19:21.

capture invaders. It is as slick as ever. You can still customising or

:19:22.:19:28.

personal Spartan, ensuring he is dressed in the highest of fashion.

:19:29.:19:33.

Your team scored. Gay Meadow. Victory! Halo fight is not perfect.

:19:34.:19:43.

-- Victory. The story is not that great but the primary mechanic,

:19:44.:19:50.

digitise destruction, is as enjoyable as ever. -- Halo Five. We

:19:51.:19:59.

have been is seeking about solar panels. -- we have been speaking.

:20:00.:20:03.

Would you believe you can power an entire airport? It is possible. You

:20:04.:20:09.

need many solar panels and a whole lot of sons of the fortunately, we

:20:10.:20:17.

found both in India. -- lot of sun. Take a deep red. Out of the top 20

:20:18.:20:24.

of the worst cities for air pollution in the world, the top

:20:25.:20:28.

three is India. --. You can point the finger at coal and gas powered

:20:29.:20:35.

stations. You can breathe again now. We are in India. The air is not

:20:36.:20:43.

perfect on the southern tip of India but it is better than elsewhere. The

:20:44.:20:47.

views are pretty good as will. A nice place for a holiday. -- as

:20:48.:20:54.

well. When you fly in, the land of the world's first solar-powered

:20:55.:21:02.

airport, 46,000 solar panels in total. The main driver behind their

:21:03.:21:09.

airport project was avoiding skyhigh electricity bills. They needed to

:21:10.:21:12.

make enough power when the sun was out to also cover the electricity

:21:13.:21:20.

they used when the sun goes to bed. That is the reason why we have gone

:21:21.:21:24.

for a huge plant, 12 megawatts, which will be able to, in a short

:21:25.:21:31.

eerie and 6-7 hours, to generate enough electricity to reach our

:21:32.:21:38.

requirements. -- period. They are confident they can get back in five

:21:39.:21:43.

years the 10 million they have paid to build the plant. But is this a

:21:44.:21:49.

good model for others to copy? The success of solar-powered does not

:21:50.:21:54.

just depend on how much we care about the environment, or for that

:21:55.:21:58.

matter, the weather. It is also down to the money. In India, because you

:21:59.:22:05.

pay more for electricity than you get if you sell it, it makes more

:22:06.:22:09.

sense to go solar if you are going to use the electricity it self,

:22:10.:22:12.

otherwise it is going to take you far longer to make back what you

:22:13.:22:18.

spend on a shiny new solar plant. -- itself. That is fine if you are a

:22:19.:22:22.

power hungry airport, but not for the rest of us. Solar panels should

:22:23.:22:29.

get cheaper. The hopes pinned on lectures and they have to be more

:22:30.:22:33.

highly valued. That airport are telling others to look for power up

:22:34.:22:44.

in the sky, not down in the earth. -- that airport is. That was David.

:22:45.:22:51.

We will finish our solar show with, what else, but they solar bench.

:22:52.:22:57.

Yes, ladies and gentlemen, a solar bench for charging your mobile

:22:58.:23:02.

devices. They are five in London, four in Canary Wharf here. Here are

:23:03.:23:06.

the charging point. This one is for an iPhone, one for everything else.

:23:07.:23:13.

And these can be very easily replace yes, and indeed when, they get

:23:14.:23:20.

pinched. Two USB ports for your computer. -- replaced. This is not

:23:21.:23:29.

just a solar bench, it is also a smart bench. This monitors the

:23:30.:23:32.

temperature, pollution level, and ambient noise, which you can call up

:23:33.:23:39.

on the accompanying application. As if you don't have it these days. The

:23:40.:23:45.

bench has been designed by a Serbian architect. In his hometown of ELT

:23:46.:23:49.

rate you will also find a smart stray. -- Belgrade. Not just a

:23:50.:23:55.

charging station but a Wi-Fi hotspot. -- smart tree. It is

:23:56.:24:02.

charged by the sun so it can work in the dark. But that is it for this

:24:03.:24:07.

week. We are out of juice. Fortunately, I have the powers that

:24:08.:24:10.

be joined us on Twitter throughout the week. -- power. -- join. That is

it for now. See you soon.
