i'm ben bland. the headlines: tens of thousands converged on central london in protest at president trump's visit to britain. there have also been demonstrations in other cities around the country, and he is now facing fresh protests in scotland as he continues his visit to the uk. earlier, he met queen elizabeth at windsor castle and described the relationship between the us and the uk as the "highest level of special". president trump is now in scotland at his turnberry golf resort — the last stop on his trip to the uk. and three days before mr trump meets vladimir putin, a grand jury in the us has decided to charge 12 russian intelligence officers with hacking into the computers of the democratic presidential candidate hillary clinton and her party. now here on bbc news, it's click.
fed up of the football, your teeth has gone out? well, let's talk hollers instead. this weekly at the austrian grand prix. we in and do self driving car in india. —— at in —— we are in. the second is wind down before the start. and ifi drivers... formula1 has been at the cutting edge of technology and design since its creation in 1946. welcome to the pit. every year, teams compete
fiercely to outdo each other in aerodynamics, dated the indications and materials, all with one aim, to make their cars go really, really fast. and they do a really good job of making that is, as we are finding out at the austrian grand prix, lewis hamilton's ride. the show is permanently on the road with cars, drivers, engineers moving from country to country and track the track. now, these are the most expensive motorhomes i have ever seen. each of these is a lie and they just write to the seen. each of these is a lie and theyjust write to the next formula 1. theyjust write to the next formula i, them together, and that is ferrari's office for the length of the race. and ahead of the race here in austria, because of being prepped, tweaked and tested around the clock. visagie ‘s other current world champions in every other team
here, they spend millions on their carand here, they spend millions on their car and developing the technology that will hopefully win in the race. —— and like every other team. what you see it every grand prix is just the tip of the iceberg, it takes hundreds of people to develop that technology. so we went to mercedes hq to find out what really goes into winning a race. away from the truck, the people, the preparation, the planning and the decision are pivotal. hire, iam planning and the decision are pivotal. hire, i am from the bbc. hello, can i just pivotal. hire, i am from the bbc. hello, can ijust put security stickers on your phone? of course, no problem. so we are allowed to film here but i must not take any pictures with my phone. there is clearly a lot at stake here so it is no surprise that formula i is notoriously secretive, but today, we have got some behind behind—the—scenes access. this
business is big bucks and millimetres and milliseconds matter. this is known as chassis number five, lusty‘s winning power, in fact it has not even been cleaned since its last winning race in abu dhabi. but the main thing you know the standing here next to it is the amount of detail varies throughout the kind after each race, if there is something they are not happy with, it can be perfected. this was a winning car last year, so clearly it has been very successful but you obviously not happy with that because you're working on a new one, so because you're working on a new one, so what do you think needs to be improved? we are never happy with that, as you say, this was the winning carfrom last year. it was the first car we made on the back of a really big regulation change, we worked really ha rd a really big regulation change, we worked really hard on all the small bits you see around the car, which is all of the aerodynamic pieces. bits you see around the car, which is all of the aerodynamic piecesm that all of the metal bits? yeah,
every piece has itsjob, what we are not happy with this because we focus on much on that, we now need to do more on the packaging internally to make much tighter. the tidy can get it, again the better you can get there ergonomics around the car. those big black dips in the side where the echoes in the cool the engine, we think we can do some improvements around that area as well. there's so much money at stake here, how much does it cost to create a car like this, from the beginning of the process all the way through? what sort of figure would put on data? well, i can't tell you that figure but i can tell you it is many, that figure but i can tell you it is any that figure but i can tell you it is many, many million. are we talking tens of millions? tens of millions. tens of millions, over 50 million? close. crikey, would not want to pay the insurance premium on that. the operation here goes way beyond the car itself though. welcome to the race support room. when a race is
actually on, 60 members of the team are allowed to be at the track, so this provides the opportunity for more people to be looking at the dasa and making sure that vital advice can be provided. 0n the screens, advice can be provided. 0n the screens, they will be looking at a feed from the race, they will also be looking at leads on within the drivers's cars, plus all the vital and after that they want to act on. and if they want to communicate, they simply do it to a pair of these. later times, gps they simply do it to a pair of these. latertimes, gps data, everything can be tracked and analysed here, where 5000 different deter points are being assessed. information from races in europe taking just information from races in europe takingjust 0.1 information from races in europe taking just 0.1 per second to reach year or taking just 0.1 per second to reach yearor0.li if the taking just 0.1 per second to reach year or 0.4 if the date is from australia. —— data. meanwhile, this is not a practising at speed. but it is not, as i can
tell you, first—hand. —— this lot make it look easy. oh no. so it is meant to be really quick but i wasn't. meanwhile, spencer is already living life in the fast lane. thank you, and by the way, this is how you really do it. this year, mercedes has got its pitstop down to an incredible 1.85 seconds, now that is quicker than it ta kes to seconds, now that is quicker than it takes to say 1.85 seconds. it is a finely tuned operation, that the engineers practice over and over in the days before each race. is a bit ofa the days before each race. is a bit of a ballet and the ergonomics is quite important for this, there's 20
people around the car trying to do a job in two seconds and it start banging into people, then you're losing half a second or second then you start to just can't get the numbers right, and then you do not get the decision you need. the human element to this ultrafast movie is accompanied by technology, individually developed by each team. even the hydraulically powered wheel guns are a closely guarded secret. and i hear they are quite expensive? they are expensive and they move a lot of pressure on. to a year about £30,000 each? i would not know the exact cost but that sounds quite low to me. now we are going into mercedes's garage now. keeping the pit crew safe is of utmost importance. these lights, for example, let the crew no other cars have become electrified, stopping them from getting more than a nasty shock. and then there is what goes
into the cars or more specifically, what comes out of the cars, which is monitored by trackside labs and high—end scientific equipment. between every session, the cars are given the equivalent of a blood test, the oil and the fuel is taken to see if it is contaminated and that gives an idea as to the state of the engine, and that is done in the fuel that. the oil is put into a spectrum was, which tests the different metals in the fluid. the amount of the specific metal present can reveal if a particular part of the engine is the grading too quickly. —— the —— degrading. yes, these may be some of the most skilled drivers in the world but i wonder if they would struggle with driving in david reid's neck of the woods. 0k,
driving in david reid's neck of the woods. ok, here we go. hejust overta kes woods. ok, here we go. hejust ove rta kes m e woods. ok, here we go. hejust overtakes me on the inside. crazy. yeah, that is me, thank you. driving he is tough. i reckon if western autonomous car makers came here they would hide in their hotel rooms, but indian inventors see the chaos on the roads here and they want to take it on. look at this mobile footage, this rickety second—hand suv has been made single—handedly into a self driving car. it is a bit rough but it makes it down the sort of road that gets wemo very worried indeed. the man behind it is a us educated artificial intelligence specialist, he says the algorithm behind the car has been designed specially for india's nightmare roads. driving in india is very chaotic so it is very hard to predict. 0nce chaotic so it is very hard to predict. once you find a solution,
then you can apply that in any restrictive environment and it can work because you already have it working in the most difficult conditions possible. today there is a hitch, the car is refusing to drive itself, so he takes the wheel. top end driverless cars cost a bomb, they are developed by big teams, have pricey radar and lasers, and use the data maps to find their way. he is is cheap and not short on brains, his off—the—shelf cameras talk to an algorithm that reads the road talk to an algorithm that reads the roa d eve n talk to an algorithm that reads the road even without maps. india's government is against driverless ca rs government is against driverless cars because they feared job losses, but the tech being delivered here could still travel far, especially with the advent of artificial intelligence. now whether or not sometime in the future india will have d riverless ca rs sometime in the future india will have driverless cars is very debatable, however, the same technology can be used to make
india's road safer. many here place their faith india's road safer. many here place theirfaith in dashboard mounted cameras to protect their safety, but the driver assistance programme invented in bangalore might also merit a look in. so why did it go there? well, because there were policeman. this is a clever backseat driver. it measures acceleration, orientation and has four g, but also artificial intelligence. it learns what is safe and what is not, it is helping indian truckers drive better. we are tracking every single object on the road and we are basically measuring any unsafe identifying any unsafe event. we actually identifying what the
driver's movie is and if you drive a response to a positive manoeuvre or it was actually something that the driver can improve upon, and the driver can improve upon, and the driver did something that could be considered unsafe. like a london with the cops, we got the video because the system sent it back when warning sounded. 0ne rather surprising area that driverless technology is making inroads in his actually off—road. in chennai, one of india's main carmakers is developing self driving tractors in response to lower crop yields and a lack of farm workers. tractors can work around the clock, just what you need when you're up against a short window for selling or harvesting. and it has two —— when it has to happen, it has to happen right at that time or else you can actually miss the interlude for the season. it is not an easy piece of equipment
to drive every time can you get that consistent operation? and that can be done by technology. nor off-road, self driving tech has incredible potential, helping ourfarmers, disciplining unruly drivers, and harnessing chaos as a testbed for even smarter systems. hello and welcome to the week in tech. it was the wicket facebook faced fine of £0.5 million for breaches in the cambridge analytica data scandal. and we learned the scale of apple's autonomous vehicle ambitions, a court filing accusing a former employee of stealing trade secrets has revealed that 5000 the company's secrets has revealed that 5000 the com pa ny‘s staff secrets has revealed that 5000 the compa ny‘s staff know secrets has revealed that 5000 the company's staff know the project. the smart phone company has a notoriously tightlipped on the issue. across the channel, family and france have become the first to
live in a 3—d printed house. the cement filled home was built in just 54 hours, but the city's university and council behind the project thinks they could do it all again in just 33. its curved walls make the property less humid and the construction cost 20% cheaper than using traditional methods. it was also the week nvidia showed off its photography skills, using deep learning it has trained its artificial intelligence to fix cranial corrupted images. amazingly, it has learnt how to do this, having only seen corrupted ones. which means it could make restoring pictures a little easier in future. magic. and finally, mit have designed a musical instrument specifically to space travel. it contains chimes equipped with gyroscopes, that change sound depending on how they are shaken, allowing budding astronaut musicians to beat the box in the zero g. these stats for formula 1 online
lolling. these cars come around the track at more than 350 kilometres an hour, which is why more than 350 million fans tune into these races. at attracting new viewers is an issue for the sport. watching these ca rs issue for the sport. watching these cars go round and round and round is and round can get a bit warring. cars go round and round and round is and round can geta bit warring. —— boring. formula 1 are aware of the problem and part of their strategy is to use all the latest tricks and technologies to pull in new fans, especially those who play racing video games and are used to feeling like they really sitting the driving seat. sport broadcasting technology is moving at such a pace. everybody is moving at such a pace. everybody is talking about, as we said, 3—d, 360, virtual reality, that is a big
talking point at the moment. mixed reality is quite nice as well. whether that is bringing actual footage into cgi world, it works really good as an engagement tool. the demographic for a formula 1 fan is, i believe, and middle—aged man. we want to make it available for young people, boys and girls, all sorts of people. this year, every formula 1 car has one of these 360 cameras right on the front. that's correct. why have you done this? to give the public and more interactive feel, so you can go wherever the action is. and if you record it you can watch it back from whatever angle you want. have you tried this? what is it like when you look through the goggles? we haven't found anybody who hasn't been wowed by it. arid tension is to eventually streamed as live off the par, you can pick your favourite driver and have an experience with him around the track. but while this may be a
great experience for the viewer, the teams, which consider every centimetre of these cars, might not these are happy about formula 1's mandatory addition. the initial camera we used was the size of a cricket all, but that obstructed the drivers' vision. so we repackaged it and got it down as low as possible. this is the design we have come up with. i think the balance of what we have achieved from the penalty outweighs, the good outweighs the bad. and the experience is notjust about what you see, it is also about what you hear. as f1 cars have developed, that iconic engine noise has died down, and so steve and the tea m has died down, and so steve and the team plan to read it up once more. --. it has been a long-held goal of the audio department to mount a microphone in the exhaust. how hot does it get? up to 360 degrees. this microphone touched the exhaust on it and see what happens. it has to live outside the bodywork. when they come toa outside the bodywork. when they come to a corner and they change down,
before, it wasn't very emotional. now when you listen to it, it really isa now when you listen to it, it really is a rasp. it is a really emotional sound. we have had lots of feedback from around the world, from broadcasters and everybody loves it. even broadcasting these races is a huge operation, from australia to our rain to china, the broadcast centre needs to be built in a matter of days to beam this race out to more than 200 countries. —— from australia to bahrain. the most amazing thing about this broadcast centre is not all the screens and technology, impressive though it is. it is the fact that at the end of the race you just hold up these desks, pop a lid on it, and it is already in a loaded aircraft container, ready to ship to the next race. about 200 tons of equipment in this building. which takes up about two 747s. and 24 trucks,
effectively. the idea is that you can quickly get from one race to the next race. i think it is the biggest mobile broadcast centre in the world. as you say, we have come a long, with the concrete patch. away we go. we build the whole thing. last sunday you finished day race, and by thursday you have come all the way to austria and you are up and running. that's right. next thursday we will be in silverstone, fully ready. look at the man! he is not breaking a sweat. and actually, it looks like the most stressfuljob this week is being done byjen copesta ke, this week is being done byjen copestake, our star in a reasonably priced, if somewhat weatherbeaten, carr. —— car. priced, if somewhat weatherbeaten, carr. -- car. yes, i am braving this
hurricane in cologne, germany, to experience europe's most advanced weather testing centre for cars. ford built this at $108 million facility to see how its most popular models there against the most extreme conditions on earth, from altitude, high heat and humidity, sneu altitude, high heat and humidity, snell and hurricane strength winds and driving rain. there are three wind tunnels here and it has the capability of testing up to three ca rs capability of testing up to three cars at once. i pretty much control these facilities. i conduct those tests. now we have centres of relative humidity for solar radiation, for temperature. and for the airspeed. which is measured through differential pressure from the nozzle. first we are going to see what it might be like to drive your car see what it might be like to drive yourcar ina see what it might be like to drive your car in a rainforest. it gets up to 55 degrees in this room, and the humidity can go to 95%. this is one
of four temperature controlled test chambers, complete with birdsong and fa ke chambers, complete with birdsong and fake palm trees to simulate a tropical environment. it is baking and air. that is so hot. from extreme heat to extreme cold. that's be snow room. these doors are really happy. it is about —17 in here right now. at the temperature can be set to go as low as minus 30. -30, of course, is rather important for cold starts. it is important for hvac issues like the heating system, for comfort, and of course for safety, it is we have a defrosting of the windshield. they are also testing how the windshield wipers operating heavy snow. the snow is falling from above and can test the maximum stress on different parts of the car. this is impressive. it is testing the weight of the snow on the car. this is actually a realistic situation in some parts of the world, to get a big snow boulder
on the wing mirror. next we are going to see how cars are tested in hurricane conditions. we have a climatic wind tunnel, so we always control the wind speeds to simulate that the car is actually moving on the roads, we move the wind. so it is actually 156 kilometres an hour winds out of air right now, it can go winds out of air right now, it can 9° up winds out of air right now, it can go up to 160. it is testing the automatic function of the windscreen wipers, so whether or not there is an equal amount of time going between each blade. the tunnel does not just test the rain and between each blade. the tunnel does notjust test the rain and the wind, but also the effect the sun has on the car in extreme conditions. it is set up with 28 spotlights with 4000 watts bulbs to mimic the sunlight. the solar system is always interesting when it comes to heat loads that affect our powertrain and that affect vac performance. that really looks like being outside in bright sunlight. it brightens my day every time i can use it! the ability to test cars at high altitude while also simulating challenging weather
conditions is the unique feature of the test centre. they can reach heights of 5200 metres, as high as mount everest‘s northern base camp. engineers even have to take dissent brea ks engineers even have to take dissent breaks when they finish working in this tunnel. more than house of our vehicles are sold in markets globally with altitudes of more than 1000 metres. —— half. we can also simulate you pulling a trailer up the hill, on different altitude levels, so testing the powertrain, regarding what is happening in terms of temperature, how is that developing, and making sure that the ca rs are developing, and making sure that the cars are safe. we have seen everything here, but! cars are safe. we have seen everything here, but i for one am looking forward to getting back to some nice british weather. that was jen copestake, and some nice british weather. that wasjen copestake, and that's it from the austrian grand prix. i have you found it as the ruling and strange as i have. —— thrilling. you
can see a lot more photos up on twitter. thank you very much for watching and we will see you soon. hello. welcome to the weekend, which will offer a bit of cloud and some rain to parts of scotland and northern ireland, whereas much of england and wales will stay dry. here's the rain—maker — this weak weather front coming in. for saturday, it is just towards the far north, north—west of scotland. it will affect more of scotland and northern ireland on sunday. for many over the weekend there will be sunshine, there will be warmth. in fact, building warmth particularly across parts of england and wales. sunday looking even hotter in places.
a range of weather this weekend. this is what it will look on saturday morning. the cloud, some outbreaks of rain, far north—west of scotland, maybe to the west of northern ireland later in the day. yes, cloud increases ahead of that. but the further south and east you are in scotland and northern ireland there will be some sunny spells to be had. some cloud building in england and wales. you can see from the colours, warm to hot sunshine to be had. a range of temperatures, quite breezy as well with the cloud and some outbreaks of rain in north—west scotland. maybe isolated showers popping up across eastern parts of england. most will avoid that and stay dry. here is how it is looking for the wimbledon finals this weekend, the men's final could be one of the hottest for decades, coming up on sunday with temperatures around 30 celsius, if not slightly above in south—east england. heading out and about on saturday evening, a lot of fine weather to come. but through the night some outbreaks of rain moving into northern ireland and western scotland.
stay dry in england and wales. these are the overnight temperatures going into sunday morning. on sunday, scotland and northern ireland, more have cloud, more have outbreaks of rain. gradually pushing further east. it mayjust reach into the far north—east of england later today. elsewhere across western england and wales there could be showers popping up here and there. most will avoid them and stay dry. most in england and wales will hold on to the very warm to hot sunshine. temperatures will be a few degrees higher in the sunshine compared with saturday, 17 in stornoway. this weather front is taking some cooler and fresher air south eastwards across the uk. it willjust take its time. on sunday evening, not a great deal of change for the position of that front, if you are heading out and about. it will gradually slide further south—eastwards monday and tuesday, but it is a slow process. any rain on itjust becomes a few showers. we are left with something, eventually, into next week, cooler and fresher, with more cloud around and than some of us have seen recently. welcome to bbc news —
broadcasting to viewers in north america on pbs, and around the globe. my name is nkem ifejika. these are our top stories: protests across the uk, as tens of thousands of people demonstrate against president trump and his policies. more are planned over the weekend. there was pomp and pageantry. queen elizabeth welcomed the president for afternoon tea at windsor castle. there was also an apology for his interview with a newspaper and mr trump rowed back on his criticism of the prime minist calling her instead an "incredible woman". as his visit draws to a close, president trump is now in scotland. he's expected to spend the weekend playing golf at turnberry. in other news, the us justice department charges 12 russian intelligence officers with meddling in the 2016 us election.
