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


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


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


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


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


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


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


from waste emissions as possible. This facility at Imperial College


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


happened. Sleek, stealthy, futuristic


machines. These solar cars will attempt to 3000 kilometre journey


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


current started going up very quickly. The speed started going


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


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


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


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


team from Cambridge University who have worked closely with them pass


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


smaller scale jobs like microsurgery. It is also the week


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


algae. The breakthrough research here is that scientists have managed


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


living algae at the correct rate without stopping anything, and


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


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


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


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


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


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


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


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


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


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


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


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


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


offer. For 17 years I have worked as a


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


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


cameras in low light. Night. -- Nice.


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


they proved that first person shooters can work on consoles by


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


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


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


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


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


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


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


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


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


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


turret. It means you can approach tactical problems in different


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


airport project was avoiding skyhigh electricity bills. They needed to


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


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


it for now. See you soon.
