:00:00. > :00:8.9This week, walking around the world for Wonga. Quantum computers and
:00:8.0 > :00:11.light Sabre, action.
:00:36. > :00:42.How would you like to earn money just by doing this? Walking about.
:00:47. > :00:50.But, very soon, it may become a thing.
:00:51. > :00:57.Dan Simmons has been given exclusive access to a new global currency project
:00:58. > :01:03.which is backed by some big investors and means if you can walk, you can earn money.
:01:17. > :01:23.You can simply make money by walking. Step goes up, step goes up,
:01:24. > :01:42.I make more money. It's a big change in life. Do you
:01:43. > :01:49.believe it? I believe it because it is happening here. The temptation to
:01:50. > :01:50.make walking a day job. Where will they walk to? Currently they are all
:01:51. > :01:56.walking to work. So we had that crazy idea that
:01:57. > :02:00.since we are walking so much, And since we didn't find anyone who
:02:01. > :02:05.actually does that, we decided to create an app that allows anyone to
:02:06. > :02:09.generate money by simply walking. It is a crazy idea
:02:10. > :02:14.from two crazy guys. Last year's project, a $7 USB
:02:15. > :02:22.stick that acts like a computer, went from one school in Nairobi,
:02:23. > :02:27.to now being used in 87 countries. Now they have schmoozed $10 million
:02:28. > :02:30.from Japanese investors to create Unlike bitcoins,
:02:31. > :02:40.the bitwalking dollar won't be mine It will be generated
:02:41. > :02:47.by human movement. Like today's wristbands and fitness
:02:48. > :02:50.trackers, the go app counts the steps you take, shows how many
:02:51. > :02:53.bitwalking dollars you make and By now you have probably had
:02:54. > :03:12.the same thought is me. It uses GPS tracking,
:03:13. > :03:26.motion type and speed sensing, and it caps what humans can
:03:27. > :03:29.reasonably do, limiting earnings to But you will be able to buy extra
:03:30. > :03:35.bitwalking dollars to make that big And depending on who you buy from,
:03:36. > :03:54.that could make a huge impact. We have come to show you the
:03:55. > :04:00.bitwalking app. We are walking and making money. Individuals will come
:04:01. > :04:07.to you with their phone and you will see they have a balance. They have X
:04:08. > :04:13.amount of bitwalking dollars, right? Now, you would be able to sell these
:04:14. > :04:21.dollars, OK, on the international market and then they will send you
:04:22. > :04:27.real currency to a PayPal account, your back account will set that up.
:04:28. > :04:30.They build then use those bitwalking dollars to top up their account, so
:04:31. > :04:33.they can purchase something in the market. OK.
:04:34. > :04:35.Malawi stands on the verge of a food crisis.
:04:36. > :04:38.The average rural income is $1.50 a day.
:04:39. > :04:41.And the President's platitudes were swiftly followed up by a 10% tax
:04:42. > :04:49.Nobody is suggesting that bitwalking will sort this out any time soon.
:04:50. > :04:51.A growing but still small number own smartphones here.
:04:52. > :04:59.But for those few it could make a difference.
:05:00. > :05:03.This is how most people make their money in Malawi, through
:05:04. > :05:08.agriculture. But we think we have found somebody making money through
:05:09. > :05:11.IT could double the amount they earn. There is the possibility of
:05:12. > :05:15.earning $26 a month. Salim walks two hours a day to teach
:05:16. > :05:18.technology in the local school. We take walking is as simple
:05:19. > :05:20.as nature. But this time it will change
:05:21. > :05:24.my life because as I will be walking Creating a new currency is
:05:25. > :05:31.a careful balancing act. If the money behind it runs out,
:05:32. > :05:33.it falls over. But bitwalking will start
:05:34. > :05:36.in just a few countries. It has a big partner in Japanese
:05:37. > :05:39.electronics giant Murata, whose staff actually do this
:05:40. > :05:43.exercise every morning. They are also making
:05:44. > :05:46.a bitwalking bracelet to do away And there's evidence that you do not
:05:47. > :05:56.too much cash to get people on Japan's largest convenience store,
:05:57. > :06:01.Lawson, has a scheme that pays workers
:06:02. > :06:04.just $50 a year to keep fit and eat Like this scheme,
:06:05. > :06:09.bitwalking dollars will only be initially be able to spent
:06:10. > :06:12.in one store, an online one which Crucially, giving employers,
:06:13. > :06:15.sports brands, health insurance companies, or anyone who has
:06:16. > :06:18.an interest in getting us moving, to join this scheme and accept
:06:19. > :06:21.the dollars will be the real test. But let's not forget the wealth
:06:22. > :06:24.of information a project Retailers want to get to know
:06:25. > :06:30.us personally more than ever. Details about our daily routines,
:06:31. > :06:32.well, that could be And one of the main reasons that
:06:33. > :06:39.bitwalking may actually succeed. Concerns around privacy and security
:06:40. > :06:44.are being taken seriously. Whether
:06:45. > :06:47.a currency that can be endlessly printed by walking can succeed will
:06:48. > :06:50.make this an interesting experiment, as it launches this weekend
:06:51. > :06:53.across several countries, including Dan, please tell me you did what all
:06:54. > :07:03.the way from Japan to Malawi OK.
:07:04. > :07:12.Sounds like an exciting scheme. But I have to wonder what really is
:07:13. > :07:17.in it for the backers, for the people pouring loads
:07:18. > :07:19.of money into this? Yeah, it's about being part
:07:20. > :07:22.of something that will probably be The project is about environmental
:07:23. > :07:27.beliefs, it's about social equity, A lot of the companies thought to be
:07:28. > :07:41.backing this scheme, who will come on board, will be insurance
:07:42. > :07:42.companies, They'll want to be associated
:07:43. > :07:46.with something like this. And it will be in their interest
:07:47. > :07:49.because we will maybe buy more Well, if we're walking we're going
:07:50. > :07:53.to need more trainers, right? The other thing that strikes me is
:07:54. > :07:56.that at the moment bitwalking dollars can
:07:57. > :07:59.only be spent on the online store. This thing lives or dies by
:08:00. > :08:03.which companies are willing to give Yeah, it's whether people want what
:08:04. > :08:12.is on the store and whether there is enough of these products to satisfy
:08:13. > :08:14.demand, depending on how quickly people start earning
:08:15. > :08:16.these bitwalking dollars. These are the early days
:08:17. > :08:19.of a new currency, a new idea. We're not sure it's going to get
:08:20. > :08:22.off the ground or not. If it does, great, if it doesn't,
:08:23. > :08:30.that will be an Achilles heel. Can you fake it? Yes, we tried. Some
:08:31. > :08:33.of the earlier versions you can. They say they will look at the speed
:08:34. > :08:37.in which you travel, the location, where you have gone to and from and
:08:38. > :08:42.also you can't have multiple accounts. So we won't have an army
:08:43. > :08:49.of people all walking and pain in Bitwalking dollars? We spoke to a
:08:50. > :08:53.farmer. They had about 25 cars. If you put one of these on each cow
:08:54. > :08:59.they could all be earning at the same time! There is an idea! You
:09:00. > :09:03.would need 100 smartphones. In Malawi that's a tall order.
:09:04. > :09:08.Cheers. Ta-ra.
:09:09. > :09:22.Time for a quick tech news round-up. This is the week a zone project shut
:09:23. > :09:26.down. Talking, the company behind it, raised ?2 million, promising
:09:27. > :09:31.back as a small smartphone controlled zone Dull on. But it only
:09:32. > :09:39.fulfilled some of its pre- orders. -- controlled drone. I beat you wish
:09:40. > :09:42.to your phone is charged quicker. The latest phone battery tech has
:09:43. > :09:48.been unveiled. It charges your mobile to nearly half its power in
:09:49. > :09:51.under five minutes. That's ten times faster than current smartphones.
:09:52. > :09:56.Music streaming is being streamlined. Many companies are
:09:57. > :10:01.slimming down their music offering. Pandora has bought RDO. Microsoft is
:10:02. > :10:12.laying its player to rest and a Apple has shut down its music
:10:13. > :10:20.player. This phase with tears of joy is the year's most used emoji in the
:10:21. > :10:24.world. I am feeling very emojinal about that. That's round off the
:10:25. > :10:31.week with a successful crowdfunding story. Would anyone invest in the
:10:32. > :10:35.speakers? $3 million says yes. Cat ears aside, it's a speaker-
:10:36. > :10:38.headphone combination, something rarely seen on sale, perhaps for
:10:39. > :10:46.good reason. It does look rather heavy. In the UK it has been anti-
:10:47. > :10:51.bullying week this week. It is a sad fact that as our online activities
:10:52. > :10:54.grope, so do the opportunities for cyber bullying. We have been looking
:10:55. > :11:00.at some of the ways we can help protect our kids from it. As a
:11:01. > :11:05.parent of a three-year-old I can already imagine the concern when my
:11:06. > :11:10.daughter gets online. And, with over half of UK children saying they have
:11:11. > :11:14.experienced cyber bullying, with 8% saying it happens so many times they
:11:15. > :11:18.have lost count, it seems with good reason. IMT can look at some of the
:11:19. > :11:23.latest tech that could come to the rescue. -- I am taking a look.
:11:24. > :11:29.This application has-been released this week. Once a school signed up
:11:30. > :11:32.to using it in either a parent or a child can anonymously report any
:11:33. > :11:36.incidents of bullying. It could be something that happens at school or
:11:37. > :11:42.out of school, including cyber bullying. Once reported, a mental or
:11:43. > :11:49.will be the details and will either send it by themselves or reported to
:11:50. > :11:53.a teacher. Of course it is not just about reporting problems. In an
:11:54. > :11:59.ideal world situations would be seen early enough that you can prevent
:12:00. > :12:03.issues. A new tool called Online Them could do that. It keeps across
:12:04. > :12:08.social network use, so parents can spot if there's a problem by being
:12:09. > :12:11.presented with an alert. It isn't a matter of watching everything the
:12:12. > :12:17.child is typing, it still gives them freedom and privacy, it should let
:12:18. > :12:22.you know if there's a problem. Twitter described their service as
:12:23. > :12:27.not directed at children under 13 and Facebook and Instagram have a 13
:12:28. > :12:31.plus policy. So I'm sure there are plenty of times Mum or dad want to
:12:32. > :12:35.know what's going on. The website fully launches later this month.
:12:36. > :12:40.First, a child must accept an invitation for access, then it will
:12:41. > :12:43.alert parents to any questionable activity, so worrying trigger words,
:12:44. > :12:48.new friends they might not know in the real world and time spent online
:12:49. > :12:54.will all be available for parents, both in real-time alerts and through
:12:55. > :12:58.monthly reports. It will also create alerts if a child changes their date
:12:59. > :13:02.of birth or is talking to someone in a different geographical location,
:13:03. > :13:07.which could seem strange. I am now joined by the company's CEO, James
:13:08. > :13:11.Blake. One of the biggest challenges is getting the child to agree for
:13:12. > :13:17.you to look into the account. What we find is if you have those
:13:18. > :13:22.conversations and you give children access to social media on the --,
:13:23. > :13:26.then they are more willing to engage with you. Surely the child willing
:13:27. > :13:29.to give access to their parent is the child in my talk to their parent
:13:30. > :13:33.anyway? That's a good point and that's why we are keen to spread the
:13:34. > :13:40.word on this. A lot of parents to think of social media as a threat,
:13:41. > :13:44.at that happens now. This is currently UK only and will cost ?5 a
:13:45. > :13:48.month. Internationally, quite a few products include ways for parents to
:13:49. > :13:53.keep across their kids' social media better and of course many like a
:13:54. > :13:56.closer look at all their kids' Web access. Using parental control
:13:57. > :14:01.software that can also block unsuitable content. This is a
:14:02. > :14:07.Bluetooth device. It connects this to this. It is not always the
:14:08. > :14:11.parents who want to do something. This group of 11 -year-olds at a
:14:12. > :14:17.Dublin school created this Bluetooth wristband. If a pupil feels
:14:18. > :14:21.bullied, a simple press send an alert to the teacher's phone and it
:14:22. > :14:24.will record the time and date of the incident, so it can be discussed at
:14:25. > :14:28.a suitable moment. For now it is just a prototype that they do hope
:14:29. > :14:35.for funding to launch it in the real world.
:14:36. > :14:41.Unless you have been living in a galaxy far away you should know
:14:42. > :14:49.there is a new Star Wars movie on the horizon... What do you mean you
:14:50. > :14:52.don't have one of these? Not only is the about about to a weekend but
:14:53. > :14:59.there is a brand-new video game coming out. This has made me a very
:15:00. > :15:12.happy nerf herder. Fire up your light Sabre. -- lightsabre. Dispatch
:15:13. > :15:23.rebels gun. I used to do this in the playground as the six-year-old. Now
:15:24. > :15:32.I can do it from my living room. In Battlefront you can assume the role
:15:33. > :15:40.of soldiers loyal to Palpatine. Or, if you are on the side of the good
:15:41. > :15:48.guys, you can join the rebellion. This game is more about combat on a
:15:49. > :15:54.huge scale. You can play against AI opponents, but that isn't as fun. It
:15:55. > :16:05.is better to play on line with up to 40 players. One minute it is all
:16:06. > :16:14.kicking off on Hoff and the next you are underneath a transport as it
:16:15. > :16:19.powers overhead. Classic locations from the Star Wars universe provide
:16:20. > :16:24.the battleground, but they aren't the only familiar thing. Heroes and
:16:25. > :16:33.villains from the movies appear as well. Crucially, you can play as
:16:34. > :16:40.then. There is something undeniably fun about deflecting blaster bolts
:16:41. > :16:46.using the lightsaber or taking to the skies with a jet pack. Just
:16:47. > :16:56.letting loose with the dark side of the force is fun as well.
:16:57. > :17:08.(LAUGHING). That almost makes up for the Phantom Menace. Why, George,
:17:09. > :17:12.why? Almost. It falls to the dark side with the lack of locations. It
:17:13. > :17:17.is likely there will be more in the future, but only Yoda will be able
:17:18. > :17:25.to predict if the downloadable content costs more to purchase. The
:17:26. > :17:34.player can also take charge of vehicles. Like this ferociously fast
:17:35. > :17:43.speeder bike which takes a bit of getting used to. Or, you can have a
:17:44. > :17:45.spacecraft battle. While it may be easy to get cocky after early
:17:46. > :17:53.victories, aerial combat is nothing like dusting crops back home, and
:17:54. > :17:58.truly takes a while to master. And, as this is essentially a game
:17:59. > :18:01.without a story, it keeps things interesting by introducing a myriad
:18:02. > :18:11.of different game modes, like capture the flag and allowing for
:18:12. > :18:15.customisation of the character. You get more things to customise with by
:18:16. > :18:22.completing tasks. The rebel bombers have pinpointed your location. While
:18:23. > :18:25.I enjoyed playing the characters from the movies, encounters with
:18:26. > :18:31.them can be difficult. The force is strong with this game. It is fast,
:18:32. > :18:37.frenetic, and full of style, that will impress Jedi and Sith alike. It
:18:38. > :18:42.comes to consoles and computers. This grown man could not be happier
:18:43. > :18:57.that I can play with my friends in the comfort of my living room. 100
:18:58. > :19:01.years ago, this week, Albert Einstein unveiled his general theory
:19:02. > :19:07.of relativity. One of the most groundbreaking, spacewalking pieces
:19:08. > :19:13.of thinking ever. He studied and later returned to work here in
:19:14. > :19:17.zero, at the Swiss Fred rural Institute of Technology. I have come
:19:18. > :19:23.to see some pictures of the man before he was a legend. -- Federal.
:19:24. > :19:29.This was a picture of him graduating. What is most amusing is
:19:30. > :19:38.that in the third year, in practical physics, Albert Einstein scored a
:19:39. > :19:44.one, that is often. -- bottom. The theory is not that he was bad and
:19:45. > :19:51.physics by that he did not want to turn up. That is a bad haircut. He
:19:52. > :19:59.was a contrarians spirit. I think he did not like to be told what to do.
:20:00. > :20:03.-- contrarian. People told him, it is a closed science, we know almost
:20:04. > :20:08.everything. Almost. That is the magic word. There were very funny
:20:09. > :20:13.things people could not explain, like an experiment that shows that
:20:14. > :20:18.light travels in the same speed no matter the direction. Esau in that
:20:19. > :20:25.the possibility that everything we knew was wrong. -- He saw in. There
:20:26. > :20:31.was a tiny crack and he took a tool, opens that crack, and opened a new
:20:32. > :20:34.horizon for humanity. That is the most important thing. What are the
:20:35. > :20:41.theories of special and general relativity? I would love to put them
:20:42. > :20:46.in a nutshell for you but to do so I would need to accelerate at close to
:20:47. > :20:50.the speed of light. Science joke. Maybe it is enough to say they have
:20:51. > :20:58.shaped our understanding of the universe, of the calls, of the big
:20:59. > :21:03.brain. -- blackholes. -- bang. He didn't stop there, he developed
:21:04. > :21:11.quantum physics, a weird world, where things can be two things at
:21:12. > :21:16.once or be in two places at one. But he himself found the whole area far
:21:17. > :21:24.too weird. So I wonder what he would have made of what is in this
:21:25. > :21:30.laboratory. This is a laser table. You expect me to talk? No, Mr Bond,
:21:31. > :21:35.I expect you to die. That felt weird... Was that supposed to feel
:21:36. > :21:42.weird? Was that my mind? And I do it again? What does it do? -- can I. It
:21:43. > :21:48.changes the shape of an atom. This is the tool we use to control
:21:49. > :21:54.information. Why do we do it? Why? We like playing with quantum
:21:55. > :22:00.mechanics. This is a quantum computer. Believe it or not it is a
:22:01. > :22:04.very basic one. Quantum computers deal with data in a different way to
:22:05. > :22:13.normal computers. Instead of using its that are either zero or wine,
:22:14. > :22:19.these use quantum bits, they are both zero and one at the same time.
:22:20. > :22:22.Weird... What kind of problems with a quantum computer be able to deal
:22:23. > :22:27.with that a classical computer could not? One of the extent of problems
:22:28. > :22:34.is cryptography, big numbers that you cannot process in a computer.
:22:35. > :22:37.Some algorithms in a quantum computer can break into these
:22:38. > :22:44.numbers in a way that a classical computer can never do. And these are
:22:45. > :22:49.quantum bits. They are calcium atoms that can each be in two shapes at
:22:50. > :22:55.the same time. See, I told you this was weird. A chain of these canned,
:22:56. > :23:00.in theory, solve a problem extremely weekly by considering all possible
:23:01. > :23:15.solutions at the same time and jumping to the correct answer in one
:23:16. > :23:22.step. -- can. -- quickly. How close are we? This whole laboratory
:23:23. > :23:28.operates a quantum transistor many times. We need a million of them to
:23:29. > :23:34.get to a quantum computer. You need to shrink this down. Quite a bit.
:23:35. > :23:38.OK. What would Einstein have made of this? She did not like the basic
:23:39. > :23:44.laws of one to mechanics. And we have them here in this laboratory
:23:45. > :23:48.under control. -- He. -- quantum. It may have set him at ease or made him
:23:49. > :24:02.more uncomfortable. Would you like to come in so you can say, look at
:24:03. > :24:09.this. -- him to come. That is enough quantum for Click, I think. I still
:24:10. > :24:46.have not found Schrodinger's cat though. MEOW.
:24:47. > :24:49.Some of us might have had some wintry weather overnight.
