this is bbc news. the headlines: russia has signalled a shift in its military strategy towards the ukraine invasion — narrowing its focus to the east of the country. moscow says the "first stage" of its campaign is over and it will now focus on the disputed donbass region. western officials say it's a sign of failure. in the south of the country there are fears of starvation in the besieged port city of mariupol as hundreds queued for food and water. authorities are hoping russian occupiers will allow un vehicles to bring in badly needed food and medicines. president biden has visited eastern poland to express his gratitude to workers dealing with the refugee crisis — and us troops defending nato's eastern flank. mr biden also announced

a deal to provide the eu with more natural gas, to help reduce its dependence on russian energy. now on bbc news: click. as the energy crisis ramps prices up ever higher click explores whether the latest generation of solar tech make installation is a no—brainer. this week swinging satellites and fruit. sensors to keep the city that never sleeps lit up and using tech to get better at football. apparently.

why are we throwing an apple at each other?— each other? because every story is about launching _ each other? because every story is about launching satellites - is about launching satellites into orbit. which direction would have to launch it? hot would have to launch it? not unwards- _ would have to launch it? not unwards- it _ would have to launch it? not upwards. it would _ would have to launch it? not upwards. it would come - would have to launch it? not. upwards. it would come straight back down _ upwards. it would come straight back down again. _ upwards. it would come straight back down again. if _ upwards. it would come straight back down again. if you - upwards. it would come straight back down again. if you wanted | back down again. if you wanted to make it go into orbit you had to make it go sideways about 17,000 miles an hour so, as it fell, it missed the surface of the earth and just went round it. you'd make that is why rockets need so much feel. exactly. there is another way to get this up or to go that fast. any ideas? you could attach it to a long arm and then start spinning it round and round and round and round, getting faster and faster and once you are at the right speed... you let it go. that's in alness- — speed... you let it go. that's in alness. that _ speed... you let it go. that's in alness. that is _ speed... you let it go. that's in alness. that is an - speed... you let it go. that's in alness. that is an apple. l in alness. that is an apple. here we — in alness. that is an apple. here we 90- _ in alness. that is an apple. here we go. 200 _ in alness. that is an apple. here we go. 200 miles - in alness. that is an apple. here we go. 200 miles an. in alness. that is an apple. -

satellite, stick it inside a giant dart, load it on day 100 metre long arm, gradually spin it round round, faster and faster and then... let it go. at 5000 miles an hour. don't believe me? i don't blame you. this idea sounds completely nuts. ~ , ., this idea sounds completely nuts. ~ ,, ., ., this idea sounds completely nuts. ,, ., ., , nuts. well, you know what is nuts, is rockets. _ nuts. well, you know what is nuts, is rockets. rockets - nuts. well, you know what is nuts, is rockets. rockets arej nuts, is rockets. rockets are combustion chambers that burn cryogenic propellants at temperatures that are greater than the surface of the sun. they have thousands of components that are made out of the most exotic materials known to man and they are on the verge of blowing apart at any possible minute. i think spin launch is quite a bit less nuts than a rocket. i5 launch is quite a bit less nuts than a rocket.— than a rocket. is the day has one than a rocket. is the day has gone on. — than a rocket. is the day has gone on. i — than a rocket. is the day has gone on, i have _ than a rocket. is the day has gone on, i have started - than a rocket. is the day has gone on, i have started to i gone on, i have started to believe it. by getting the projectile above the

atmosphere, you have done away with the need for most of your fuel and most of your weight. without air resistance, much smaller rocket can then get the satellite up to 17,000 miles an hour and into orbit. spin satellite up to 17,000 miles an hour and into orbit.— hour and into orbit. spin get ou hour and into orbit. spin get you most — hour and into orbit. spin get you most of— hour and into orbit. spin get you most of the _ hour and into orbit. spin get you most of the way - hour and into orbit. spin get you most of the way there i hour and into orbit. spin get l you most of the way there and then there is a smaller rocket that gets you all of the way there. it is passively stable so there is a heavy tip at the front. that provides passive stability that stabilises it like a dart so it becomes outer that a bit sideways it automatically stabilises. how many cheese _ automatically stabilises. how many cheese is _ automatically stabilises. how many cheese is desperate then? 10,000 cheese at peak speed. you can put people on this, can you? well, you can put people in but you won't get people out. these guys put an iphone four into the accelerator got up four into the accelerator got up to 12 and a half thousand.

it still works. the company says it is eventually planning for up to five launches a day and it will cost have $1 million power launch compared to 7 million for a rocket launch. before then, testing is ongoing using the 33 metre arm in new mexico and a 12 metre i'm here in long beach, california. and i have been invited to witness a test launch first hand. now, the 12 metre accelerator will not be launching into the air. this much smaller projector will beef fired down a cheap and straight into a steel plate. what happens to those activities launch from that? this mostly turns to dust at the end of the tunnel.- this mostly turns to dust at the end of the tunnel. oh, my cosh. the end of the tunnel. oh, my gosh- now. — the end of the tunnel. oh, my gosh. now, where _ the end of the tunnel. oh, my gosh. now, where were - the end of the tunnel. oh, my gosh. now, where were we? i the end of the tunnel. oh, my i gosh. now, where were we? 0h, gosh. now, where were we? oh, yeah. gosh. now, where were we? 0h, eah. ., , ., . gosh. now, where were we? 0h, eah. ., ., ., ., yeah. now you are going about as fast as _ yeah. now you are going about as fast as a _ yeah. now you are going about as fast as a jet. _ yeah. now you are going about as fast as a jet. p _ yeah. now you are going about as fast as a jet. p projectors i as fast as a 'et. p pro'ectors and as fast as a jet. p pro'ectors and spinning * as fast as a jet. p pro'ectors and spinning armour i as fast as a jet. p projectors and spinning armour made l as fast as a jet. p projectors. and spinning armour made of carbon fibre, pretty much the

beneath the bright lights of this city that never sleeps seems to be a sensible side. it is now gambling on becoming a world leading smart city, a safe, efficient and sustainable, still kind of noisy, oasis. las vegas is not the obvious place to be trying to be a sustainable city. as for the big bright lights. um? for the big bright lights. why not las vegas? _ for the big bright lights. why not las vegas? everything else he was — not las vegas? everything else he was big, over the top. we had — he was big, over the top. we had a — he was big, over the top. we had a capital entertainment around _ had a capital entertainment around the world. i not be the world's— around the world. i not be the world's smartest city? the city that is — world's smartest city? the city that is leading—edge. right above _ that is leading—edge. right above your eye these palm trees that are — above your eye these palm trees that are made out of steel but they— that are made out of steel but they are — that are made out of steel but they are solar panels. so sustainability is kind of in our— sustainability is kind of in our dna. all the electricity the city— our dna. all the electricity the city of las vegas consumes we produce. so we are, in that

monitors have also been built in to monitor the flow of carbon heavy traffic and we know this is not a city polluted only by day. at night time this is one of the busiest spots in vegas. there are delivery vehicles dropping off, minicabs picking up, so that kerb—side activity is being tracked by cameras and sensors on the scene as a vehicle stops it will feature here on the screen. it has two one half minutes to do whatever it needs to do and once that comes down to do and once that comes down to zero, an alert will be traffic warden to come and give the ticket. this can also help keep law and order. in a desperate video analytics are being used to see if anybody is climbing up on the sino doing any sort of vandalism. there will be an alert triggered and then a speaker will tell them that they need to get down. it is also looking at how much rubbish is around so there is a fair bit to clear up, someone will be told to do so. and this

isjust will be told to do so. and this is just the start. next is the tracking of the huge sprawling buildings here and how they use their energy. at the heart of all this is data and that data is being shared through what is called a digital twin. what is being shared through what is called a digital twin.— called a digital twin. what we are building _ called a digital twin. what we are building as _ called a digital twin. what we are building as a _ called a digital twin. what we are building as a digital- called a digital twin. what we are building as a digital brain | are building as a digital brain fora— are building as a digital brain for a city— are building as a digital brain for a city which enables all of the sensors placed around the city monitoring everything from air quality to traffic, pedestrian movements, security, be brought into a single system and then— be brought into a single system and then processed using artificial intelligence. you will — artificial intelligence. you will he _ artificial intelligence. you will be able to go anywhere in the city— will be able to go anywhere in the city virtually and see things— the city virtually and see things like how many spaces are available — things like how many spaces are available in the car park or how— available in the car park or how many, you know, watts of electricity— how many, you know, watts of electricity are being used by vehicle _ electricity are being used by vehicle charges and that sort of thing _ vehicle charges and that sort of thing. the technologies employed in this project are 56. artificial intelligence are 5g. artificial intelligence are ai. another one is block chain. another— ai. another one is block chain. another one is digital twins. use — another one is digital twins. use the _ another one is digital twins. use the internet of things and that means everything around us is becoming smart and connected

us and elsewhere but will expand to 150 countries. the us national traffic safety is opening a formal investigation into phantom breaking by cars using the company driver assistance system autopilot were slowing down suddenly, even when there were no hazards ahead. finally, researchers have designed a bipedal robot that combines walking with flying. standing at two and her feet this little robot can pop, jump, feet this little robot can pop, jump, fly and solve problems. it can also walk a tightrope and skateboard. living the dream. researchers hope leo could help open up new environments for robotic exploration. it isjust environments for robotic exploration. it is just a question of whether as humans can keep up. there are all kinds of tech been woven into football to improve both the players and the beautiful game itself such as video assistant

referee and goal line technology. what about us? the fans of the sport. the sunday league. the ones who want to go pro one day play every week until we cannot run any more. well, now there is tech for us, too. a few companies to provide state—of—the—art kits to the pros have now created consumer versions of their products. first up we have got these vest worn by players underneath their shirts. they house pods which are trackers that collect different data points on the wearer. and now letting the public give it a go, too. they've gone into partnership with arsenal who have used a wearable tech for years that consumers will be wearing a slightly different vest but the black pods they will be wearing are exactly the same ones they use. here is where it gets a little bit more interesting. i have got the kit on and i am out on the pitch ready. but then... i am out on the pitch ready. but then... iam in out on the pitch ready. but then... i am in a lot of pain. i've had to sit out for now

pros. it is a virtual reality set up with foot trackers so users can kick around a digital ball. now they are offering a bit of a scaled—down version for the consumers on less powerful headsets like the quest. we're still really testing the user. it is called player 22 and though you can only use your hands and not your feet it still has a number of tools to test the user be at their reactions, fitness and accuracy but there is also a very football specific drill. heading. something that can hurt and be a lie. so, heading. something that can hurtand be a lie. so, to heading. something that can hurt and be a lie. so, to make it less painful, they've made a drill for it in vr. 0k, it less painful, they've made a drill for it in vr. ok, that is enough. what? 0h. that was weird. the heading itself, it was really accurate but not having the pressure of the ball in your head is kind of strange. i could get used to it but i'm curious a lot of people

know you are not actually hitting a ball you are still moving your head around quite a bit and your brain inside might be bouncing around. during a game we heading may be up to 20 balls depending on their position from but that is going to be multiplied significantly during training. heading a ball as i think four times more impactful than not so obviously that level of safety is increased by using vr and removing that impact with the ball itself. to be fair, even the kids were enjoying it. that the kids were en'oying it. that was amazing. i the kids were enjoying it. that was amazing. that _ the kids were enjoying it. that was amazing. that was - the kids were enjoying it. trust was amazing. that was really good. was amazing. that was really nood. , , was amazing. that was really mad, , , . ., ., was amazing. that was really nood. , , it was amazing. that was really good-_ it is - was amazing. that was really good-_ it is a - good. this is cool. it is a aood good. this is cool. it is a good thing _ good. this is cool. it is a good thing because i good. this is cool. it is a i good thing because heading is something that is banned in games for children under 12 in the uk foot of the fa have also made new measures to reduce the amount of headers in professional training sessions to lower the risk of long—term damage so maybe theyjust need to switch to heading virtual balls instead. last up we have wearable trackers that go inside these malls which fetter

banjo bits. these are used by pro clubs but now the company has come up with their consumer version. you put the trackers inside the modes and then slip them onto your bits, collect them onto your bits, collect them to the app via bluetooth and then play away. as you are playing they are supposed to pick up physical metric similar to stat sports but also things like kick velocity, number touches and more. and you can also compare yourself to the pro players on this platform, too. i pro players on this platform, too. , ., ., too. i use it a lot coming back from injury — too. i use it a lot coming back from injury so _ too. i use it a lot coming back from injury so i _ too. i use it a lot coming back from injury so i could - too. i use it a lot coming back from injury so i could come i from injury so i could come back to the levels i was when i was fed. the feedback gave me that and i knew what i had to work on so it really accelerated me getting back to where i was preinjury.- where i was prein'ury. even an in'u where i was prein'ury. even an injury these _ where i was preinjury. even an injury these trackers _ where i was preinjury. even an injury these trackers are - injury these trackers are useful but there is a problem with all of the products that we have looked at. just so expensive. 200 quid. 250 quid. and only £11 in the store but

to get it quest in the first place, at least £300. it is hard to justify playing that much for extra data. we are kicking around a ball in a park, its fee. i remember something said to me. quick legs but quick thinking, you no. especially making the right decisions on the pitch, will make your world class player. if you look at me just based on physical data when i was younger i probably would not have made it so everyone is on a different path so we need to respect that. so maybe these are nice to haves rather than essentials. eating that next level of footballing greatness takes more than just extra data. so maybe tech is not the answer. that was 0mar. he left his ball behind. 0h, answer. that was 0mar. he left his ball behind. oh, my goodness. what are you doing in the middle of this pack? relaxing. yoga.- the middle of this pack? relaxinu. youa. �* ., relaxing. yoga. are you really? on my coat. _ relaxing. yoga. are you really? on my coat. in _ relaxing. yoga. are you really?

temperatures early on saturday could be close to freezing in some rural areas. it'll warm up quickly. any mist and fog in northern ireland will lift. it will stay quite cloudy in the far north of scotland. otherwise lots of sunshine, just a bit of fairweather cloud once again and the winds will be light. and temperatures on saturday similar to what we had on friday, could again make 19—20 degrees in some northern parts of england. a reminder that on saturday night, the clocks spring forward by one hour as we move into british summer time. so, an hour less in bed. for many people waking up across the eastern side of england, it could be a cloudy start, though, on sunday. we've still got high pressure around, but there's more cloud coming in off the north sea. it could be quite low cloud, misty as well. it means it's going to be a mild start to sunday across eastern parts of the uk. a little bit chillier further west. there's the cloud that we've got across eastern areas. it will tend to filter its way through the midlands towards east wales. some of that cloud could linger all day through parts of the midlands, around some eastern coasts of england, but for many, i think

the sunshine will come through. it may not be quite as warm as it has been of late. more sunshine, though, further north for scotland some and northern ireland, so again here, temperatures are likely to reach 17 degrees or so. major changes, though, heading into next week. high pressure that's brought the fine, warm weather is no more. pressure's going to be dropping. and at the same time, we're going to find more cloud moving in as well. not everywhere, mind you. and many places are still going to be dry even though pressure is falling, but we could see some rain across these central areas. north and south of that, though, i think we are likely to find some sunshine. and the temperatures are still reasonable for this time of the year. 16 degrees in the sunshine, won't feel too bad at all. but it is a downward trend, really, through next week. not only will see more cloud and an increasing chance of getting some rain, those temperatures are really going to be dropping away as well. so, rather than being warmer than average, it will get colder than average, especially later on next week as the wind changes to more of a northerly. that brings the colder air, and across some northern parts of the uk, it could even

bring some snow.
