0:00:02 > 0:00:06Ah!! Ah!!
0:00:06 > 0:00:07Ah!
0:00:08 > 0:00:10CRASHING
0:00:10 > 0:00:11HORSE NEIGHS
0:00:26 > 0:00:29This week's Click will fly by, I promise you,
0:00:29 > 0:00:32if you're on one of the electric bikes that we'll be wheeling out.
0:00:32 > 0:00:35And if you can't get a signal to watch the big match,
0:00:35 > 0:00:40help may be at hand, but probably not from where you might think.
0:00:40 > 0:00:44We'll also find out how wireless broadband may soon be helping
0:00:44 > 0:00:47the emergency services, and we have the app that helps you
0:00:47 > 0:00:50find the fake amongst all the photos in Webscape.
0:00:55 > 0:00:57Welcome to Click, I'm Spencer Kelly.
0:00:57 > 0:01:00Welcome to the Queen Elizabeth Olympic Park.
0:01:00 > 0:01:02A couple of years ago, this was the place to be
0:01:02 > 0:01:05if you wanted to be part of a major sporting event.
0:01:05 > 0:01:09There is another one, the World Cup final, coming up this weekend,
0:01:09 > 0:01:11unless you are watching a repeat, in which case...
0:01:11 > 0:01:14..congratulations to Germany.
0:01:14 > 0:01:16Congratulations to Argentina...
0:01:16 > 0:01:19..for winning a really close fought battle.
0:01:19 > 0:01:20On penalties.
0:01:20 > 0:01:22What was essentially a walkover.
0:01:22 > 0:01:25Many people, sport fans or not,
0:01:25 > 0:01:29make plans to catch these big events live on TV
0:01:29 > 0:01:32if they can get the signal.
0:01:32 > 0:01:34That was the problem Dan Simmons faced
0:01:34 > 0:01:37when his plans to catch the match were thrown up in the air.
0:01:43 > 0:01:47It's being touted as the best World Cup ever.
0:01:47 > 0:01:49So, if you have not got a ticket for the final, it's
0:01:49 > 0:01:51time to make some plans.
0:01:52 > 0:01:57Obviously, one of the best places to see the match is probably here,
0:01:57 > 0:01:59on Copacabana Beach.
0:02:02 > 0:02:05Or, you could watch it at a bar or cafe.
0:02:09 > 0:02:11Or, you could always watch it at home.
0:02:13 > 0:02:16One place football fans definitely won't want to be
0:02:16 > 0:02:18when the big game is on is up in the air,
0:02:18 > 0:02:23because here, well, there is plenty of good movies, but no match.
0:02:23 > 0:02:26Ladies and gentlemen and children,
0:02:26 > 0:02:28the World Cup match from Brazil will shortly be shown
0:02:28 > 0:02:32live on Sport24 Channel on board this aircraft.
0:02:32 > 0:02:33Thank you.
0:02:37 > 0:02:38For the first time,
0:02:38 > 0:02:43this World Cup will be shown live to passengers midair, by seven
0:02:43 > 0:02:48airlines signed up to show a live sports channel on long haul flights.
0:02:48 > 0:02:51It's not just a business class offering, either.
0:02:51 > 0:02:55Even the seats at the back get a good view, and it seems to have caught on.
0:02:56 > 0:03:01So, how do hundreds of people each get a live feed at the same time
0:03:01 > 0:03:04while travelling at 600 mph?
0:03:05 > 0:03:09From its control room in Los Angeles, Panasonic Avionics tracks
0:03:09 > 0:03:15the 17 satellites that cover most flight paths around the globe.
0:03:15 > 0:03:18Each one can deliver up to 50 megabits per second, but that's to be
0:03:18 > 0:03:23shared between all the aircraft within that satellite's footprint.
0:03:23 > 0:03:26Although the Wi-Fi on board can get speedy,
0:03:26 > 0:03:29it needs to be shared itself between the passengers.
0:03:29 > 0:03:32So, a section of the bandwidth is set aside solely for
0:03:32 > 0:03:35the streaming of live sport.
0:03:35 > 0:03:39Next year, the company will start focusing the data signals
0:03:39 > 0:03:42specifically to just a few aircraft at a time,
0:03:42 > 0:03:44almost doubling data speeds.
0:03:45 > 0:03:49Specially made antenna on each aircraft need to work in some
0:03:49 > 0:03:52of the most challenging conditions any electronics could face.
0:03:52 > 0:03:54First, being baked,
0:03:54 > 0:04:00and then frozen to the sub-zero temperatures of 35,000 feet.
0:04:00 > 0:04:03Next, the equipment needs to be checked for precision
0:04:03 > 0:04:06and efficiency A fraction of a degree out
0:04:06 > 0:04:11and the data rate falls dramatically which could mean no football.
0:04:11 > 0:04:14You have multiple satellites that are required to provide
0:04:14 > 0:04:16this broadcast globally.
0:04:16 > 0:04:18How do you transition from one satellite to another?
0:04:18 > 0:04:22Let's say, from Europe to the Middle East, changing satellites,
0:04:22 > 0:04:27it has to be timed exactly the same to be able to transition,
0:04:27 > 0:04:30leave one satellite, reposition the antenna on the aircraft to the
0:04:30 > 0:04:34next satellite, and pick up in the broadcast where you left off.
0:04:34 > 0:04:36Quite a challenge.
0:04:36 > 0:04:39Like other big matches, a single video feed
0:04:39 > 0:04:42of the World Cup final will be sent to each aircraft, with the passengers
0:04:42 > 0:04:47then opting in to watch it, so you can't pause or rewind the match.
0:04:47 > 0:04:51Almost 50 airlines have signed up for the satellite data service
0:04:51 > 0:04:57on board, which could also be used to personalise our in-flight experience.
0:04:57 > 0:05:01In a year or so, expect airline apps to offer you the opportunity
0:05:01 > 0:05:06to choose what you want to watch on board before you're on the aircraft.
0:05:06 > 0:05:08You'll be able to pair your own device
0:05:08 > 0:05:11to your seat number, so that you can pick from the menu what you
0:05:11 > 0:05:14would like to eat, and it will also tell you
0:05:14 > 0:05:18whether there is something interesting to look at outside the window.
0:05:20 > 0:05:23How airlines use and charge for the new services that in-flight
0:05:23 > 0:05:27data can now offer is still being worked out.
0:05:27 > 0:05:30But as live sport is offered free of charge on more planes,
0:05:30 > 0:05:36there will be even fewer places where fans will have to miss a big match.
0:05:36 > 0:05:38Presuming, of course, they're still interested.
0:05:41 > 0:05:45Dan Simmons, a man who mysteriously disappears from the Click office
0:05:45 > 0:05:47whenever the football is on.
0:05:48 > 0:05:52This World Cup has certainly had its fair share of magic moments.
0:05:52 > 0:05:56Diving, goalkeeping substitutions, biting?
0:05:56 > 0:05:59The crystal clear pictures being beamed back from Brazil have
0:05:59 > 0:06:03allowed us to see the action in greater detail than ever before.
0:06:03 > 0:06:06But through it all, some BBC engineers have been conducting
0:06:06 > 0:06:10trials which could make future matches look even better.
0:06:12 > 0:06:17For a number of years, 4K, or ultra- high-definition, has been
0:06:17 > 0:06:21touted as the next big thing in television viewing.
0:06:21 > 0:06:25While fans the world over have been gripped by football fever,
0:06:25 > 0:06:28members of the BBC's RND team in London have been testing
0:06:28 > 0:06:30the logistics of receiving a live
0:06:30 > 0:06:354K video stream from a number of World Cup games in Brazil.
0:06:35 > 0:06:39Three games in total, including the final, will be streamed in ultra-
0:06:39 > 0:06:44high-definition, which offers four times the resolution of Blu-ray.
0:06:44 > 0:06:47The games have allowed the engineers involved to get closer than
0:06:47 > 0:06:49ever before to the action.
0:06:49 > 0:06:52Everybody has talked about four times the resolution that
0:06:52 > 0:06:55you get with 4K, and that's true.
0:06:55 > 0:06:57We've been able to look at things in the crowd,
0:06:57 > 0:06:59read people's watches on their hands
0:06:59 > 0:07:01in the crowd shots.
0:07:02 > 0:07:04The detail on these bigger screens,
0:07:04 > 0:07:10we've been using maybe 65 inch screens, and the difference
0:07:10 > 0:07:16between HD and 4K on those screens has been quite noticeable.
0:07:16 > 0:07:19The operation has presented its fair share of logistical
0:07:19 > 0:07:23challenges, but that's all part of the testing process.
0:07:23 > 0:07:27Of course, those behind the project are keen to point out that just
0:07:27 > 0:07:28because they are testing 4K,
0:07:28 > 0:07:32doesn't mean it will be coming to our homes just yet.
0:07:32 > 0:07:35Obviously, people see 4K televisions appearing in shops,
0:07:35 > 0:07:39but you have to think about the whole of the production infrastructure
0:07:39 > 0:07:43needed to actually be able to deliver that content.
0:07:43 > 0:07:45I think it will be like HD,
0:07:45 > 0:07:49where HD production took off much more before HD distribution.
0:07:49 > 0:07:53I'm sure we'll see a similar theme with 4K.
0:07:53 > 0:07:55By the time the next World Cup rolls around,
0:07:55 > 0:07:59who knows how we'll be watching TV, or if will even exist,
0:07:59 > 0:08:02but I have a feeling we said that during the last World Cup,
0:08:02 > 0:08:04so maybe don't hold your breath.
0:08:04 > 0:08:07If you have any thoughts on that, or anything else in the programme,
0:08:07 > 0:08:09please feel free to e-mail us.
0:08:09 > 0:08:12Now, it's time for tech news.
0:08:12 > 0:08:14Passengers around the world are being advised
0:08:14 > 0:08:17to ensure that electronic and electrical devices in
0:08:17 > 0:08:21their hand luggage are sufficiently charged to be switched on.
0:08:21 > 0:08:24Updated transport rules from several governments state that
0:08:24 > 0:08:28if a device doesn't switch on, you won't be allowed to bring it.
0:08:28 > 0:08:31The new security checks have been introduced as a result of what
0:08:31 > 0:08:34American officials are calling a credible terrorist threat.
0:08:34 > 0:08:38Google Glass has been hacked so it can, apparently,
0:08:38 > 0:08:41be controlled by its wearer's mind.
0:08:41 > 0:08:44User experience agency, This Place,
0:08:44 > 0:08:46has combined the specs with a mind wave mobile
0:08:46 > 0:08:49headset that measures brainwave signals.
0:08:49 > 0:08:53It allows users to take photos and upload them to social networks
0:08:53 > 0:08:55just by thinking about it.
0:08:55 > 0:08:57The aptly named MindRDR software
0:08:57 > 0:09:00is open source, and developers believe it could give hope to
0:09:00 > 0:09:03those unable to communicate verbally.
0:09:03 > 0:09:06Although they might not be able to get decent reception,
0:09:06 > 0:09:093-D smartphones have boldly gone into space.
0:09:09 > 0:09:13Powered by Google's 3-D mapping system project, Tango,
0:09:13 > 0:09:14the phones have been sent
0:09:14 > 0:09:19to the International Space Station to work with NASA's robotic spheres.
0:09:19 > 0:09:23It's hoped that the phones will act as the eyes and brains of the droids,
0:09:23 > 0:09:26allowing them to better navigate around the ISS.
0:09:26 > 0:09:27Yep, it's official, we live
0:09:27 > 0:09:31in a world of flying space robots equipped with phones.
0:09:36 > 0:09:39Any large event like the World Cup or the Olympics brings with
0:09:39 > 0:09:41it security concerns.
0:09:41 > 0:09:44There are a large number of people in one space,
0:09:44 > 0:09:48and therefore it becomes a target for an attack.
0:09:48 > 0:09:50There are new technologies around that help the police
0:09:50 > 0:09:53and emergency services deal with such events,
0:09:53 > 0:09:56and those developing the tech are now urging governments around
0:09:56 > 0:10:02the world to save dedicated broadband space just for that purpose.
0:10:02 > 0:10:06Jen Copestake was asked to breach security to test some new systems.
0:10:13 > 0:10:16Imagine someone is trying to place a bomb under a car.
0:10:16 > 0:10:19That's what I have been asked to do here to create a fictitious
0:10:19 > 0:10:21security alert.
0:10:21 > 0:10:25I'm testing new broadband technology for public safety and policing
0:10:25 > 0:10:28from Motorola Solutions.
0:10:28 > 0:10:33I may think I'm not being watched, but this is no ordinary car park.
0:10:33 > 0:10:37Despatch to car one, pushing video now. Over.
0:10:37 > 0:10:41This is car one, we are receiving live video. Over.
0:10:41 > 0:10:45This exercise is being run at Motorola Solutions research
0:10:45 > 0:10:48centre in the south of England.
0:10:48 > 0:10:50Large amounts of data, like maps and video
0:10:50 > 0:10:53collected on the security threat, me,
0:10:53 > 0:10:58are sent live to the patrol car that acts as a mobile response unit.
0:10:58 > 0:11:01All the security video taken throughout the day has been digitally
0:11:01 > 0:11:03analysed for blue,
0:11:03 > 0:11:07isolating me amongst the crowd by the colour of my dress.
0:11:07 > 0:11:10The result? A layered video of my movements.
0:11:11 > 0:11:15Next, facial recognition data can be fed directly to the police car.
0:11:16 > 0:11:19It won't be long before I'm under arrest.
0:11:19 > 0:11:23Can you send us a picture of the suspect, over.
0:11:23 > 0:11:27Wireless broadband technology brings some of the same abilities
0:11:27 > 0:11:30that you and I as consumers rely upon.
0:11:30 > 0:11:33It brings the ability to virtually bring scenes to life
0:11:33 > 0:11:38from a remote location by transfer video, by creating ways to communicate
0:11:38 > 0:11:40that are not possible with just the spoken word.
0:11:40 > 0:11:44A picture is worth a thousand words, video's worth maybe a million words.
0:11:44 > 0:11:47The critical communications industry has been moving
0:11:47 > 0:11:50away from narrowband private mobile radio networks
0:11:50 > 0:11:52towards superfast 4G broadband.
0:11:54 > 0:11:57This will allow vast amounts of data to be shared fast
0:11:57 > 0:11:59between first responders.
0:11:59 > 0:12:02In the future, paramedics working on a victim in an ambulance could
0:12:02 > 0:12:06send data back to medical specialists at base.
0:12:06 > 0:12:09Sensors on firefighters can monitor core body temperature,
0:12:09 > 0:12:11heart rate and blood pressure.
0:12:11 > 0:12:14Police officers could see a hazard in advance.
0:12:14 > 0:12:17What it allows in a public safety environment is for a CCTV
0:12:17 > 0:12:21camera of a specific area, maybe around the corner from where the
0:12:21 > 0:12:25that officer is, to be streamed into the officer's device,
0:12:25 > 0:12:28so he can see clearly what is around the corner before
0:12:28 > 0:12:31he has to put his head around the corner.
0:12:31 > 0:12:34The pressure it could put on networks is already clear.
0:12:34 > 0:12:38When Hurricane Sandy hit the east coast of America in 2012,
0:12:38 > 0:12:42it only took a few hours for communications to jam,
0:12:42 > 0:12:44causing chaos for first responders.
0:12:48 > 0:12:51We're all using so much internet bandwidth in our daily lives
0:12:51 > 0:12:54that the spectrum is getting crowded.
0:12:54 > 0:12:57Unless bandwidth is reserved for the emergency services,
0:12:57 > 0:13:00public safety could be compromised.
0:13:00 > 0:13:03Many countries don't have dedicated bandwidth for first responders
0:13:03 > 0:13:07and this will become an increasing problem worldwide.
0:13:07 > 0:13:11Spectrum problems are ubiquitous in the world,
0:13:11 > 0:13:15It's a challenge. Scarce resource, highly valued by lots of services.
0:13:16 > 0:13:20Right now, Europe hasn't moved to allocate spectrum.
0:13:20 > 0:13:21But there are many issues to overcome.
0:13:21 > 0:13:23Privacy is one.
0:13:23 > 0:13:28With vast amounts of data flowing around, how do you control who sees it?
0:13:28 > 0:13:32And prioritisation. How do you avoid data overload?
0:13:32 > 0:13:36Anything is actually possible. The number of devices and so on.
0:13:36 > 0:13:40It's very important to note that when moving into a dangerous situation,
0:13:40 > 0:13:44an officer doesn't want the data fed to him.
0:13:44 > 0:13:47He needs somebody telling him in his ear what he's about to face
0:13:47 > 0:13:50and he wants to know somebody can talk back.
0:13:50 > 0:13:54So it picked me up, suspect Jen in the blue dress.
0:13:54 > 0:13:57Technologies like this are developing rapidly,
0:13:57 > 0:13:58especially in the US.
0:13:58 > 0:14:02Those backing these systems are pressing for dedicated
0:14:02 > 0:14:04broadband space for public safety.
0:14:04 > 0:14:09Otherwise our crowded online lives may have an unintended impact on security
0:14:09 > 0:14:11and the work of the emergency services.
0:14:13 > 0:14:15Jen Copestake.
0:14:15 > 0:14:18That funny looking building is the Olympic velodrome.
0:14:18 > 0:14:20With the Tour de France in full swing,
0:14:20 > 0:14:23we thought it was time we showed you this.
0:14:23 > 0:14:25It looks like an ordinary bike.
0:14:25 > 0:14:28It is heavier than an ordinary bike
0:14:28 > 0:14:32because it's a prototype of a new e-bike, an electric bike,
0:14:32 > 0:14:36which goes by the grand name of the Vanmoof 10 Electrified.
0:14:39 > 0:14:43If you've ever ridden an e-bike before, the first thing you'll
0:14:43 > 0:14:47notice about this one is it doesn't have the unsightly battery pack
0:14:47 > 0:14:49below the saddle.
0:14:49 > 0:14:54That's because the power cells are built into the frame itself.
0:14:54 > 0:14:56It takes about three hours to charge fully
0:14:56 > 0:14:59and can give you between 19 and 37 miles of range,
0:14:59 > 0:15:03depending on terrain traffic, weather and how you're cycling.
0:15:04 > 0:15:09This is a so-called pedelec. The electric motor only works when
0:15:09 > 0:15:11you pedal so you do have to do some work.
0:15:11 > 0:15:14But as soon as you do, the power kicks in,
0:15:14 > 0:15:20helping you whiz up hills and whistle along the flat at top speeds of 18mph.
0:15:21 > 0:15:25Although you can cycle at quite a pace, I have to say you notice the
0:15:25 > 0:15:29electrical assistance most when you are pedalling slowly or up a hill
0:15:29 > 0:15:34because the motor kicks in and it's actually difficult to cycle slowly.
0:15:36 > 0:15:41There's almost no effort on my part at all to go at this speed.
0:15:41 > 0:15:43HE LAUGHS
0:15:43 > 0:15:45It's fast!
0:15:47 > 0:15:52That's why there's a button to switch down from 100% power to 50%,
0:15:52 > 0:15:55although to be honest I still had trouble keeping it slow and
0:15:55 > 0:16:00there's no way of actually switching it off from the control panel.
0:16:00 > 0:16:03There is a button for the LED lights built into the frame
0:16:03 > 0:16:05and even a remote control.
0:16:05 > 0:16:07The bike won't work without it,
0:16:07 > 0:16:11so it kind of acts like a theft deterring immobiliser.
0:16:11 > 0:16:16The dawn of the electric bike has certainly come and gone before.
0:16:16 > 0:16:21But as long as you have 3,000 to spare, this one could be here to stay.
0:16:23 > 0:16:26Cycling is becoming increasingly popular in town.
0:16:26 > 0:16:30Because of that, many cities now have a community bike scheme,
0:16:30 > 0:16:33where you can hire special bikes from docking stations
0:16:33 > 0:16:36using your credit card and then return them
0:16:36 > 0:16:39to a different docking station later, where your card is charged.
0:16:39 > 0:16:43Now, it's usually the docking stations themselves
0:16:43 > 0:16:47that are the brains of the operation but in Copenhagen, in Denmark,
0:16:47 > 0:16:51the community bikes have become smart.
0:16:51 > 0:16:52Lara Lewington took a ride.
0:17:01 > 0:17:06Copenhagen, one of the cycling capitals of the world.
0:17:06 > 0:17:10A place where there are as many bikes as there are inhabitants.
0:17:13 > 0:17:17In the '90s this was the first capital city to install a cycle hire
0:17:17 > 0:17:21system, so it's little surprise they've just upgraded to
0:17:21 > 0:17:22one at the cutting edge.
0:17:24 > 0:17:28When it comes to hiring a bike, it needs to offer something extra.
0:17:28 > 0:17:31Not only are these electric but they also come complete
0:17:31 > 0:17:35with their own built-in, apparently vandal proof, tablet.
0:17:35 > 0:17:39When it comes to reserving, booking and paying for one, you can
0:17:39 > 0:17:40do it all on this.
0:17:45 > 0:17:48You can select manual or whatever level of pedal power
0:17:48 > 0:17:50assistance you desire.
0:17:50 > 0:17:52You can go for longer distances.
0:17:52 > 0:17:56Even if you have a manual bike and you want to go 5km,
0:17:56 > 0:17:59the fastest and easiest way to go is on an e-bike
0:17:59 > 0:18:01and you get there without sweating.
0:18:04 > 0:18:06I'm not that confident on a bike.
0:18:06 > 0:18:10I was actually quite relieved that even with the electric element
0:18:10 > 0:18:14kicks in, it still feels comfortable and stable and safe.
0:18:14 > 0:18:17And the thing is, it's very easy to stop.
0:18:18 > 0:18:23The tablet offers GPS travel guides enhanced for cycling, making the bikes
0:18:23 > 0:18:26a liberating way for tourists to explore the city
0:18:26 > 0:18:30or for commuters to get to unfamiliar locations.
0:18:30 > 0:18:32There's an option to check train times
0:18:32 > 0:18:35and you can even book a bike for someone else, pre-setting
0:18:35 > 0:18:39a meeting destination to make sure they head to the right place.
0:18:40 > 0:18:44At the same time, the GPS tracks who is going where, when
0:18:44 > 0:18:48and that data is sent home every ten seconds,
0:18:48 > 0:18:53meaning information on battery life, location and usage is constantly being collected.
0:18:53 > 0:18:57It is, of course, early days but the open platform means
0:18:57 > 0:19:00the potential for software development is huge.
0:19:00 > 0:19:05One idea they are trying out at the moment is location-based marketing.
0:19:05 > 0:19:07But there's also scope for improving the cycling
0:19:07 > 0:19:09experience for the whole city.
0:19:09 > 0:19:12We'll get a lot of data from the bikes.
0:19:12 > 0:19:15We are already getting that, the average length of the trips,
0:19:15 > 0:19:18the speed people are cycling with, because we can then adjust
0:19:18 > 0:19:22the traffic signals to the speed of the bikes in the morning.
0:19:22 > 0:19:24If you have a headwind, maybe they change with them,
0:19:24 > 0:19:26than if you had the wind in the back.
0:19:28 > 0:19:32Is looking down at a tablet when on a bike safe, though?
0:19:32 > 0:19:35Apparently there's been no problem yet.
0:19:37 > 0:19:40If you've finished your journey and there's no room in the docking
0:19:40 > 0:19:44station, you can actually just leave the bike in a designated safe zone.
0:19:44 > 0:19:49You put the stand on, lock it and you can leave. But right now I'm in luck.
0:19:50 > 0:19:53250 of the bikes have been up and running for a couple of months
0:19:53 > 0:19:57now but the hope is it will soon become thousands.
0:19:57 > 0:20:04Then, maybe other cities will follow Copenhagen's example once again.
0:20:04 > 0:20:07Lara Lewington. If you've been following the Tour de France, you'll know that
0:20:07 > 0:20:10one of the major talking points this year is the issue of people
0:20:10 > 0:20:14taking selfies too close to the cyclists.
0:20:14 > 0:20:17Of course these days it's hard to work out which pictures are real
0:20:17 > 0:20:21and which ones are just people having fun with Photoshop.
0:20:21 > 0:20:24However, don't fear. Kate Russell may very well have the answer.
0:20:24 > 0:20:26Here comes Webscape.
0:20:26 > 0:20:30What if you have a spectacular shot and you want to prove to
0:20:30 > 0:20:34others it hasn't been photoshopped or tampered with?
0:20:34 > 0:20:38Izitru will help you prove it's genuine and unmodified.
0:20:41 > 0:20:45You probably won't have any need to prove your family holiday
0:20:45 > 0:20:49photos are real but, if you've captured a newsworthy moment
0:20:49 > 0:20:54or are taking evidential shots for an insurance claim or to sell an item on
0:20:54 > 0:20:58an online auction, then this service could really come into its own.
0:21:00 > 0:21:03You could also use it to prove something you captured
0:21:03 > 0:21:06to enter a photographic competition has not been tampered with.
0:21:06 > 0:21:09Just upload your shot and the website will host it,
0:21:09 > 0:21:12together with prominent trust ratings.
0:21:20 > 0:21:24As cities sprawl out and 24-hour lifestyles takeover,
0:21:24 > 0:21:27light pollution is a growing problem.
0:21:31 > 0:21:33As well as limiting our view of the heavens,
0:21:33 > 0:21:37unless you have blackout curtains, it has a negative effect
0:21:37 > 0:21:42on our well-being, as sleep patterns are largely regulated by light.
0:21:42 > 0:21:46If this concerns you, a couple of interesting citizens science projects
0:21:46 > 0:21:50aim to track the extent of light pollution around the world.
0:21:50 > 0:21:54Android has the free Loss of the Night app which allows you to
0:21:54 > 0:21:56monitor and report light levels in your area.
0:22:04 > 0:22:05If you have an iPhone, there's
0:22:05 > 0:22:08a similar project called Dark Sky Meter.
0:22:08 > 0:22:11The app isn't free but it's not expensive.
0:22:11 > 0:22:15The result can be viewed on the project's live map.
0:22:29 > 0:22:31While some cities are always in the light,
0:22:31 > 0:22:34some music remains in the dark.
0:22:34 > 0:22:37Spotify revealed statistics on its fifth birthday
0:22:37 > 0:22:39that said 80% of the 20 million or
0:22:39 > 0:22:43so songs in its database had been listened to at least once.
0:22:43 > 0:22:45Read between the lines, though,
0:22:45 > 0:22:50and you can deduce that at around 20% have never been played.
0:22:50 > 0:22:56That's four million unheard tunes that Forgotify wants to help
0:22:56 > 0:22:57you find.
0:23:03 > 0:23:08Spotify is famously not terribly musically discerning about what
0:23:08 > 0:23:11it allows to be uploaded to its library.
0:23:11 > 0:23:17So, there are some fairly shocking tracks in the fabled no plays list.
0:23:17 > 0:23:19It is an interesting journey, nonetheless,
0:23:19 > 0:23:21and I did come across the occasional gem.
0:23:27 > 0:23:30You'll need to be logged in to a Spotify account to play,
0:23:30 > 0:23:36as you dig deeper and deeper into the musical rabbit hole of unloved tunes.
0:23:43 > 0:23:48Kate Russell, whose taste in music turns out to be just as bad as mine.
0:23:48 > 0:23:51We've made it to the top of the ArcelorMittal Orbit at the Olympic Park,
0:23:51 > 0:23:54where you get not only great views of the park,
0:23:54 > 0:23:57but also the city of London just over there.
