to be getting through. gets your attention straight away. you think, "0h, what's going on?" i think everyone takes notice when a child says something, and because they don't — you know, they always mean it. so what does somebody who studies the psychology of the human voice make of this? research shows that deeper adult voices are perceived by humans as having more authority than higher voices, so a child's voice wouldn't have that authority. but perhaps it's the shock factor of using a child's voice. it may be just a short—term result from this shock factor, but the station says injuries have dropped by nearly two thirds since megan's announcement started. do you think adults listen enough to children? um, no. they should listen more to children because, sometimes, children are right. dougal shaw, bbc news. somebody who is always listened to is mike bushell. having just made the cut,

it's been a great start to the 3rd round open, for england'sjustin rose, while chris wood is also making a charge. still a way to go, to make up enough ground on the leaders at carnoustie, who don't go out until this afternoon. let's join our man there, john watson. looking at the conditions, we can perhaps see why there are some really good scores so far? yes, much more favourable conditions, certainly benefiting the early starters. you talked about chris wood, the englishman, he is three shots off the lead. he reduced five birdies through the first seven holes, his best open finish was tied for third in 2009. justin rose doing well, he started on three over and just made the cut last night. he has moved to one under par. let's have a quick look at the leaderboard. zach johnson and kevin kisner are still in front on six under par. as we

know, tommy fleetwood put himself in contention with that superb round of 65 yesterday. just one shot further back. rory mcilroy with consecutive rounds of 69 and four under par. rory mcilroy was due to go out at 22 four. fleetwood is at ten to four. zachjohnson four. fleetwood is at ten to four. zach johnson and kevin four. fleetwood is at ten to four. zachjohnson and kevin kisner, the last pairing at four o'clock this afternoon. we can expect more good scores to come. england play india in london later on the first day of the women's hockey world cup. jo currie is at the queen elizabeth olympic park in london for us, and jo the action already under way? 15 minutes into the world cup, welcome to a sweltering hot in london olympic park. 100,000 tickets have been sold for the biggest women's sports event of the year.

the match has kicked off behind me. it is germany against south africa. germany already have a 1—0 lead. all eyes a re germany already have a 1—0 lead. all eyes are going to be on the hosts, england. they are one of the big favourites coming back. they are ranked second. they are the reigning olympic champions. they have not had a bad year so far, having claimed a bronze medal at the comrade games earlier this year. —— bronze medal at the comrade games earlierthis year. —— —— commonwealth games. they are battling it out to get their hands on that world cup trophy. the netherlands are ranked number one and also european championships to new zealand or the reigning commonwealth games champions. england play india at two o'clock. it isa england play india at two o'clock. it is a sell—out. england play india at two o'clock. it is a sell-out. that is all the

sport for now. now time for cabaye click. this week, i give you your next car. your next backpack. and your next pair of shoes. welcome to one of the biggest airshows on the planet. this is the farnborough international airshow, a chance to see the newest aircraft up close, and witness them being put through their paces. i mean, really, something that big should not be doing that. alongside the air displays, this is where the aviation industry does its business, and on the first

of seven show days, orders were made for more than 300 aircraft and deals of almost $50 billion were struck. oh, my goodness. i mean, it'sjust so incredible to see what these enormous flying bits of metal can do. but interestingly, the next big thing in aviation could be quite small, and very personal. this is the blackfly, a new type of single—passenger craft. now, you may have never heard of opener, the company that made it, and that's because it has been operating in secret for the past nine years.

the eight rotors are powered by a battery, offering travel distances of about 25 miles. in the us, speeds would be restricted to 62 mph. you don't need a runway because this pav, or personal aerial vehicle, can take off and land vertically. in fact, it doesn't even have wheels, and that is partly due to its amphibious ambitions. it can land on water if necessary. now, after you have towed it to your take—off spot, it's time to quickly assemble the craft. opener is targeting enthusiasts who have open stretches of uninhabited grassland that they need to get between. well, who doesn't? america's faa has approved the design, which has an autopilot function. in fact, it's even said that riders won't have to hold a pilot's licence. it is one of several companies hoping to change how our skies look. earlier this year, we reported on uber‘s plans for sky taxis. bedroom craft is being developed to

—— bedroom craft is being developed. this week, aston martin joined the growing list of companies with personal aviation in its sights, when it showed off its concept design, and rolls—royce pitched in with its own helicopter—like four—seater. so personal aviation is fast becoming a thing. opener hopes to be selling the blackfly from next year at the cost of an suv, and while that's not an exact figure, it seems that it would be within the price range of quite a few people in the us and elsewhere. now, just after the blackfly was announced, it was revealed that the man funding it all is google co—founder larry page. now, this is a guy who seems to collect flying cars like they're cadillacs, because this week there was another big announcement from his fleet, this time in las vegas, and david lee

travelled there in a boring old normal plane to check out the kitty hawk. this used to be a top—secret project, but not anymore. you are seeing the kitty hawk flyer in all its glory. so many people think this thing is the first step in a dream that we as humans have had for a long time — the dream of flying around in a flying car. this test flight flown by brittney lasted about nine minutes. right now, battery capacity allows for around 20 minutes, but the speed is limited to six mph. not exactly fast travel, but you can cut them some slack. this is a flying car, after all. i really don't have to think about a lot, other than letting the aircraft do its thing, and then putting in where i want to go. it's, like, that simple.

that's the beauty of it, because you're about, you're flying, beautiful scenery, and i just tell it where i want to go. i don't have to ever think about anything, the controls, so it's like, all you have to think about is how awesome it is to fly. kitty hawk has created this small hangout at the edge of a lake near las vegas. the location is important. it rarely rains, but it does get incredibly hot, and sometimes too windy to fly. the vehicle itself weighs less than 254 pounds, which is important, because it means the us aviation authority does not require a rider to have a pilot's licence. instead, kitty hawk puts them through a training regime that lasts just 90 minutes. first a simulator, then a real machine, strapped to the ground, and then this fun ball—pool, with a serious purpose. this is where you practise getting out, if the flyer was to crash into the water. 0k.

there's not much of an interior yet, but i imagine they'll be working on that. and here is the seatbelt. sadly, they wouldn't let me fly it myself, but i did at least have a chance to try it out for size. so i'm in, and then i have the controls here. one of them does altitude, the other one is the direction of where i'm travelling. these things, they are going to crash one day, right? have you had any issues? has one fallen out of the sky yet? we have not had a single — flying people, we have not had a single person go in the water. we do a ton of flight testing on this, and as we're always developing new things, we find bugs and we fix bugs. that is a huge core part of what we do. as is often the case with new and exciting technology like this, it's not a question of whether they can do it, but whether we're going to be allowed to. in orderfor this flyer to be a reality in our daily commute, a lot of laws need to change

to make it possible. but it's not the only way humans can get into the sky. dan simmons has been looking at another idea. that is so loud, but he does it with such grace. so the jetpack does 250 mph. it will go up to 500 metres, which is like 1,500 feet. it can fly for ten to 15 minutes, and it only weighs about 65 kilos. the main straight at goodwood is more familiar with fast cars than jetpacks screaming past the stands, but as part of the future lab exhibition here, this man dreams of us all taking to the skies.

this jetpack — as soon as the whole thing is off, you do want to clear all of that fuel and all of that baggage. it might be thejb11, it might be new, it might be extra—special in terms of the amount of power and agility it offers david as he goes flying around this circuit, but once he's done with it, just get the thing off. great landing, like it. tell me a bit about this. so jb11, six engines, this is our latest version. sojb11, this is the 11th iteration. so there have been ten before this. flew around statue of liberty injb9, that was two years ago, but it only had two engines. so you have some redundancy. you can lose one of these thrusters and you will stay up. and the computers have got to be robust. where are they? so that one is the starting one, that is on the throttle. and then there's a computer system in here, that's our main computer, and this distribution system, and then each of the engines has their own computer. so there are six computers,

then a master computer and throttle computer, so a lot of computers. how long has it taken to get to this stage with a jetpack? over 12 years. i started 12 years ago. and it's gone quickly, but it's been a hell of a process. and now you have got this, this is supposed to be in a sweet spot. is it ok if ijust sit here? i'm not going to take it up for a spin. but from this position, what am i looking at here? so on the pilot's side, you're looking at the left engine and the right engine, so you're looking at all the engine information on this side. so how hot they are, how fast they're spinning, what's the battery voltage, how much fuel you're using, et cetera, that is this side. and when the batteries turn on, you see all of that information there. and those leds are basically — if it's green, everything is good. fly. if it's orange, probably want to start thinking about it. if it's red, definitely land. jetpack aviation says the jb11

would sell for north of $300,000, if the public could be trusted to be let loose with one, which is why it's not for sale, although the us military is looking into its use, as they have been with jetpacks for the last 50 years. the new design will wow crowds around the world, but it could also offer us the chance to have flight sessions in the near future. you know, my idea is that young kids or 14—year—old kids, you know, my daughter included, should be able to fly in one of these on a tether system, in complete safety, and get a feel for the future of aviation. because it's not the aeroplanes anymore. it's about the capacity for individuals to move around the environment, you know, go from their house to the shops, or their house — you know, to be able to take an autonomous flying vehicle from one place to another. it will happen. it's not to happen tomorrow, it will happen. hello and welcome

to the week in tech. it was the week that google was fined a record £3.9 billion for illegally cementing its dominant position in search. amazon'sjeff bezos was announced to be the richest man in the world, worth a whopping £113 billion. and netflix saw its shares drop by 14% after recording disappointing subscriber growth. it was also the week that shares in tesla plummeted after elon musk insulted one of the rescuers of 12 thai footballers from a cave. he was angry after vernon unsworth called his mini—submarine, designed but not used for the rescue, a pr stunt. musk later apologised for calling unsworth a paedophile on twitter. facebook‘s mark zuckerberg controversially defended the rights of its users, including holocaust deniers, to free speech. he said, while he finds

holocaust denial offensive, he doesn't think facebook should take down content just because people may be getting information wrong. the remote north coast of scotland will be the first place in the uk to get a spaceport, which could be ready to start small rocket launches within four years. and finally, do you talk to your plants? would you like to take them for a walk, but don't have time? now you can employ this adaptable hexa robot, which can take your plants for a walk, letting you know when they need water, and even dancing when they're happy. the company hopes that one of these robots can eventually look after creatures on mars. away from the amazing aerobatics of the farnborough airshow, the aviation industry is big business here, and showcasing its newest innovations. one of the mid—term goals of the field is to make electric

and then possibly solar—powered planes. well, these are the first pictures of the latest airbus zephyr plane, an unmanned solar aircraft which is currently circling above arizona, where it's hoped it can stay up continuously for 30 days, at altitudes of 70,000 feet in the stratosphere. and today, at farnborough, airbus has given us an exclusive look at the new zephyr s. and this is the new uk production facility for the zephyr s. and there is — 25 metres long, just those two little propellers. and the most amazing thing, i think, is how much it weighs — 75kg, which is about the same as me. high above commercial aircraft and bad weather, there are two suggested uses for this so—called high—altitude pseudo—satellite — remote surveillance, or as a communication platform in remote parts of the world. so this is reaching out to those 4 billion people in the world today

that have no link to the internet, and this is a game changer, which the zephyr can bring into play here. so the problem with a satellite, it's great for consistency, but what happens when you want to change a payload? you're not bringing a satellite down and saying let's quickly change the payload. and this is where the beauty of the zephyr comes in, is the flexibility. it means we can bring that bird down, we can put a new payload on, and we can send it back up again. and this means we can take the new leaps in technology that are coming, we can take advantage of that, and just put it on the zephyr and bring it up again. the main challenge is keeping planes like this aloft at night. without the sun to power them, they need to rely on rechargeable batteries to keep the propellers turning. the key is to allow the plane to gradually lose height in the dark but ensure it's still above 50,000 feet by the time the sun rises again. this height is called the dawn altitude. we just got the news that

came in from the team, we have set a new dawn altitude record of 59,000 feet, which is outstanding and really going beyond expectations that we had. such are the harsh conditions and constant recharging cycle in the stratosphere, the zephyr will need to come down every three months to have its batteries replaced. and on top of all this, airbus is also collaborating with facebook, which recently ditched its own solar plane project, aquila. we have been talking about the so—called wonder material that is graphene for a while. this one—layer thick carbon was the world's first 2d material. a million times thinner than a human hair, and stronger than steel. and it's flexible, superlight, conductive, has thermal properties. the list goes on. so while it may be commonly

used in smartphones, for example, why is it not, well, everywhere? the trouble is there is no set standard for measuring graphene, which means manufacturers who could be incentivised to use it don't really know what they're working with. but that could be about to change. a launch today at uk parliament aims to standardise what constitutes graphene, and it has come some way since we first talked about it on the programme a few years ago. in fact, i've even been testing some graphene trainers. they feel pretty normal to run in, but the benefits are really meant to be felt further down the line. it's that durability and flexibility, particularly over tougher terrain, that's where they claim to come into their own. but the potential uses of the material are vast and varied, keeping researchers busy. here at the national

physics laboratory — pretty impressive, isn't it — not only are they testing the latest ways that graphene can be used, but also, they have this chemical mapping system which is just one part of the equipment to actually test the graphene content in any item. is it notjust as simple as working out what percentage of graphene an item would need to be to qualify as graphene? the first issue is understanding the measurement of the material itself to say, well, is there graphene in there? when you look in a black powder there could be anything in it, so that is the first issue of having measurement procedures everybody can follow. if it's not dispersed through it, if it's clumped in one part, it may actually make the composite worse. i've actually got my hands on a whole vial of graphene. and with such qualities, isn't this rather a lot? what could you do with it?

these are graphene flakes in a powder. you would imagine adding this into a composite. if you think of something like lightweight planes, fuel savings, this is the material you would need to put into the composite. ok, and for our batteries and devices, are these sorts of flakes you'd use? yes, for energy storage, even things like making flexible electronics as well. back at farnborough i've come to see the latest research by rolls—royce into keeping our current crop ofjet engines safe and well maintained. sometimes a bit of debris can get sucked into an engine and hit one of the blades and damage it. it might bend it out of shape ever so slightly. that's really dangerous, because as this engine spins millions of times the blade could end up cracking. what you normally do is send somebody to ever so slightly shave away the damage. they remove the part

of the blade that is bent. well, this is a prototype robot, which you can attach to the outside of the engine, and then a tele—operator can remote control this part of it. they can be anywhere in the world. they lower this tube into the engine, there is a camera and a scanner to assess the damage, and when they find the damage they use this tiny little dental drill to remotely shave away the damage. bob's your uncle. one day, engine damage could be assessed by this little fella and his friends, wiggling into the crevices of the machinery. if me or you went and inspected the combustion chamber it would take us hours, just because we've got to get inside with a flexible bit of spaghetti and look around and map everything that's in there, all those features. with these, we can send in maybe five or ten and they can go to different parts of it and transmit the images back. we've got a very quick map of the expected area.

the whole point is trying to make it efficient and get the plane back out flying. we've got a group of people working on it at the moment, doing some pretty exciting stuff, walking around upside down on bits of engines. it looks like science fiction but there are areas where we are building the new key building blocks to make it work. they walk upside down in engines? yes, they have to, because we need to inspect all the surface area. how do you achieve that? are they magnetic? i can't disclose too many details about that, that publication is in review just now. that is the secret sauce? this isjust a prototype. the real robot will be half the size. now, from robots that can repair damage to robots intent on destruction. let's head to china for something completely different. shenzhen bay sports centre. home to the region's biggest sporting events, with room for 20,000 spectators. and every summer, this place hosts

one event with a difference. welcome to dji robo masters, a big, loud, robo shootout. in each round, two teams remote control their robot tanks around a complex battlefield. the aim — to take out the opponent's base robot while defending your own. and before the 2018 robo master event this weekend ijoined one of the teams for some vital practice. nihau, i'm spencer. let's do this. let's do this! talking team tactics is going to be difficult on account of the chinese—english thing. go! this competition is all

about attracting and inspiring engineering students who get to massively redesign and modify the starter kits which contain four ground robots and a drone. now, these already come with lasers for training. they fire balls at the opposing team's pressure sensors, and they have wacky wheels. this is huge fun! the whole thing feels like a really realistic videogame. come on! what started as a competition for local universities has now become a mega event, attracting talent from all over the world. students work for months honing their designs. turning these beasts into ultimate fighting machines is no easy task. to prepare students with this kind of system thinking, we need to give them a project where they can integrate the different areas, learn how to co—ordinate as a team, they are collaborating with each other. that's what we did, actually, in company, for a drone,

we have electrical circuits and mechanical designs, and a drone is similar to a robot. so it is a very good way for them to train. each bot is transmitting back a live point of view image. any delay in transmission and you're toast. am i dead? i was the longest lasting of the three of us. we would hope that a robotics competition like this, in the future, can become a popular sport where people don't admire those athletes, but they admire engineers. brilliant! and that's it from my a350 and my attack chopper for this week. i hope you enjoyed what you've seen. don't forget, there are loads of extra photos on twitter, and we're on facebook as well. thanks for watching,

and we'll see you soon. hello, there. despite quite a bit of cloud to start the day, it will be drier for most, brighter, with more sunshine throughout the rest of our saturday. with those lengthy spells of sunshine coming through, temperatures are expected to be higher than those of yesterday. the fly in the ointment is more rain coming in on the weather front into the north west of scotland later. but for most of us, temperatures are higher. 27—28 in the south—east, perhaps the odd sharp shower, but fairly hit and miss. through the evening and overnight, the mist and low cloud returns, particularly to the north and west. as the humidity rises it will start io become a little bit more uncomfortable for sleeping again. 20 degrees potentially in london itself, more likely

the teens for any of us. any mist and fog will clear quite readily. we have more cloud for the north—west of scotland, northern ireland, north—western fringes of england and wales, but warmerfor most in eastern scotland, the east of northern ireland and pushing 30 degrees, i think, tomorrow, across the south and east of england. goodbye for now. good afternoon. the multi—billion pound project to install smart energy meters has been heavily criticised by a group of mps. they've warned it's likely to save customers just £11 per year. the report says the programme risks falling behind schedule and ending up heavily over budget. our business correspondent joe lynam reports. malcolm got a smart meter... it is the biggest infrastructure project you have probably never heard of, costing £11 billion they mass roll—out of smart meters into 30

million homes across the
