this is bbc news, the headlines... hurricane ian is battering the us state of florida with powerful winds and a huge storm surge that has flooded communities along the southwest coast. governor ron de santis said the hurricane would rank as one of the top five ever to strike the state. the bank of england's taken emergency action over the market turmoil in the uk saying it would buy government bonds to protect the uk's financial stability. the pound plunged — and the cost of government borrowing soared — after the conservatives announced their new economic approach last week. iran's president's accused protesters of misusing the death of mahsa amini to cause riots. as protests continued for a 12th day, mr raisi said the death of the young woman while in the custody of the morality police had saddened everyone and was being investigated

with transparency. now on bbc news, click. this week, we're back in berlin as europe's largest tech show powers up. yeah, we'll glide through the halls to see what's big, what's new, and what's bonkers. what are you doing? multitasking. meanwhile, lara's been to the british seaside. not on holiday, though. i've been looking at how 56 is hoping to make our coastline safer. and it's robot floors! chris has been making a right mess to put

vacuum bots to the test. our robot now has a tail. yeah, i'm not sure that was the aim. it's big, brash, bright, bold, really big, and it's back. did i mention it's big? set in the heart of berlin, ifa is europe's largest tech expo. and for the first time in such a long time, i got to come back to the coolest city in the world to see what's cooking. ifa is back to its heady mix of showiness and practicality. a place where your fridge can be part of a massive light show, with colour—changing panels and a party mode. your garden is also now portable, and lives indoors. those could do with a water, though. and, yes, they do go big

on their washing machines. either that or i've shrunk in the wash. disinfection robot. all right, i'm disinfected, thank you. here's a tip — if you're ever asked to do an action photo, do launch yourself into the air. it always makes you look good. i've really missed this place. we used to come here every year to take the temperature of the tech world mid—summer. and let's say that, after a couple of years on ice, it's definitely warming up again with a few old favourites being reheated. although some do have a new twist. here's samsung's odyssey ark, a curved oled screen that can be used in landscape or portrait mode for a different, all—encompassing view. and, for those who don't know whether they actually want a curved screen or not, the lg oled flex will be out later this year, promising to bend to your will. we have been wondering how

big events like this would fare post—pandemic. i mean, would we all still want to fly in from all over the world and gather in one place? or are we happy to do our business and our product launches online these days? injanuary, the us equivalent of the show, ces, was decidedly smaller and quieter. but i'd say that, while ifa definitely had fewer visitors, its chairman told me that the show was up to about 85—90% of its pre—pandemic size. we all have learnt in the pandemic that those online tools work very well, but we have also learned that we missed the handshake. there's a longing for the personal interaction, especially when you make new contacts, and especially at ifa, where you have such a need for haptic and tactile products, actually. and this is the reason why we we're doing ifa. yeah, the show�*s back on its feetjust in time for the next crisis. we're here in germany. energy is a big question as well. cost of living is a big issue.

and i think for the consumer electronics companies that are here, they were just starting to get to grips with the supply chain issues, component shortages. it's starting to ease up — and now, we've got another body blow for them. yeah, the biggest issue hanging over a massive trade show that's trying to persuade us to spend money on stuff that uses energy is... ..right now, we're a bit short of money. and energy. around ten halls�* worth of ifa were dedicated to the smart home, which traditionally has meant plugging in bits of your life that previously didn't even need to be plugged in. and that's why many of the big names here were keen to attach a particular word to their product. sustainability... and sustainability... sustainability... the argument is that the bits that are now connected to the grid can help you monitor and control your energy consumption in a way that ultimately leads

to smarter power management. we see, at ifa, manufacturers of devices who help you control the climate. when a window is open, it automatically sends a message to the smartphone and turns down the heating. great idea, perhaps, but let's not forget they're not new ideas. but they do seem more relevant right now. one of the big overarching themes of the show has been the environment and sustainability, but we shouldn't lose sight of the fact that we've all come here on an aeroplane. i do feel, for the first time, it is a story that is starting to get more prominence and therefore every company has to have a story. but the problem is, you have to cut through this kind of desire to do green—rinsing or greenwashing on what's actually real. there are definite attempts to be green here. well, there's some greenery about, anyway. i'm just not sure it's enough to solve the energy crisis.

but, in amongst the weeds, there were some definite energy positives. this is the ecoflow delta, which consists of this solar panel here and one of these three boxes. and what's interesting is, on a bright, sunny day, the solar panels can charge this box here in about four hours and give you 3,600 watt hours, which means you could keep your fridge running for about a day—and—a—half, maybe even two days. it uses a fast—charging lfp four—battery system, like those used by tesla. and, like many ideas that originated before the current energy crisis, its time mayjust have come. so people are looking for these renewable, safe, sustainable solutions to generate their own power, to store it and to use it. we have the global situation of higher energy costs everywhere, of energy insecurity. so, in a lot of the regions in the world, there is...

power is not a not a very secure feature. you have outages a lot. you have crisis everywhere in the world. so, it more and more becomes, let's say, that consumers and people start to think about, "ok, which other way do i have to have my own secure power generation independently from any grid, right, from any provider?" so, you could keep your essentials going for a few hours during a blackout, but with a maximum output of 1,800 watts, you could blow it all — literally — on some high—powered necessities. just don't get these two the wrong way around. i bet that's the closest you've ever been to either of those tools. you know me too well. right, we'll be back at ifa later in the programme. the only thing i really missed this year was you. but you've been to the great british seaside instead, haven't you? yes, i've been to dorset, which is beautiful and has hopefully been made safer thanks to 5g.

every year, around 22 million people flock to the spectacular jurassic coast in the south of england, so public safety is a serious concern. whether it's hiking along the coast or swimming in the sea, huge crowds and a wild location means serious incidents are inevitable. it wasn't so long ago that if you got yourself into trouble, you'd need to make your way up here to use this. but now, 5g has connected the coast. and the initiative to save lives starts out at sea with the world's first 5g—connected buoys. the data they collect includes currents, wave height and tidal conditions, and that's all beamed back to shore with speeds claimed to be 8,000 times faster than current technology used out at sea. lower latency is so vital because it enables real—time decision—making, so any changes

or sudden changes in the weather can be notified and people are kept up to date to help keep safety, and make sure that people are utilising the coastal environment sensibly. these buoys offer more than just sensor data. aquaculture — farming at sea — is a growing part of dorset�*s economy. and 5g—connected cameras underneath the buoys offer continuous monitoring of seaweed growth — and also make sure that no—one steals it. believe it or not, people do steal that kind of crop - along the jurassic coast, - and we're feeding those images via high—definition cameras into an ai algorithm, - which is analysing the growth rates and saying, "is this - seaweed developing at the rate that we would expect it to?" i add the sea data connected by the buoys is also transmitted via 5g to connected signs dotted along the coastline, providing potentially life—saving real—time information

for visitors. the buoy is sending information about things like sea _ temperature, sea state, wave heights _ to connected signs. and the whole point, really, l is to give people a now—cast, rather than a forecast| of what the conditions are like in the water. the connected sides also have footfall counters to relay real—time data back to emergency services to prevent overcrowding. and, with millions of annual visitors coming to a spot with limited connectivity, the 5g network could make a vital difference. if you come down to the beach here, there is no cellular connectivity, which is quite annoying if you've just come here for the day to play with your kids, or whatever. but actually, from a public safety point of view, it presents real challenges and can really be the difference between saving lives or not. and, whilst erosion has helped shape this stunning coastline, it can also be dangerous.

so sensors have been installed along the coast that use the 5g network to track ground movement. we're also using 56 _ technologies to connect sensors along the jurassic coast. it's very unstable, and it erodes quite quickly — l and that's what makes it so stunningly beautiful. i and if we can use thati connectivity to monitor the movement of the land - and make sure that we can make changes to the way we manage the coast as a result of that. information and that data, l that's good for local people, and it's good for the visitors who come here. _ so, with a 5g network that connects sensors out at sea, in the cliffs and onshore, this coastline has been revamped for the 21st century, letting visitors enjoy and explore this beautiful landscape safely. in this week's tech news,

ride—hailing giant uber is investigating a hack to its computer networks. it says several internal communications and engineering systems have been compromised after a hacker showed the new york times evidence they had access to e—mails, cloud storage and code archives. videos and images from the next instalment of the grand theft auto franchise have been leaked online. the long—awaited game will be the next in the series following 2013's grand theft auto v, which is the second bestselling video game of all time. the hacker claims to have the game's source code, too. the source code is literally the thing that runs the game, the nuts and bolts of the game, if you like, and if that has been leaked then it means that rockstar's rivals could potentially look under the bonnet of the game and see how it works, potentially steal some of the trademark ideas that make it so successful. streaming site twitch has announced it will be banning gambling sites including slots,

roulette or dice games from mid—october unless they're licensed in the us or other jurisdictions that provide sufficient consumer protection. and, finally, sony's announced plans to start developing its own brand of hearing aids. the devices, which will be available over the counter, are designed to be able to pick up and use as naturally as contact lenses. at tech expos like ifa, in berlin, you'll find all sorts — big and small, weird and wonderful. and, while there wasn't a lot that was brand—brand—new this year, we were able to check in on some technologies that we've had our eyes on for a while. now, we've seen glasses like these get better and better over the years. i'm currently playing a playstation 5 game. it's completely excluding my vision at the moment,

so i can't see you at all. but if i do want to see what's going on around, then i can go full sci—fi bug—eye. just to point out, this is not augmented reality. there's no motion tracking in this, so it's not like i can walk around the room and see objects hanging and sticking in space. but this is compatible with pretty much anything that you can connect through a usb—c cable. so, i... ..am off for a drive. yeah, over time, you will see previously ground—breaking tech becoming mainstream at these events, and you mightjust come across the next big thing, too, if you walk the floors for long enough. mind you, they're darn clean floors these days. this is what happens when these things breed. look, they're all over the place. but how do the latest robot vacuums shape up? time to compare some of the best. here's chris fox with a sweeping review.

chris fox: welcome to top of the bots. we're putting four robot vacuum cleaners like this through their paces on our assault course to see who cleans up. let's have a look at the contestants. we have the eufy robovac x8 hybrid, the miele scout rx3, the irobot roomba j7, and the proscenic m8 pro. we'll be testing them against a hand—held unit — the dyson vis detect absolute. can the bots beat it? there are many different features built into each of these vacuums that can be used to tailor your cleaning experience. but today, we're only planning to test their most basic functions. completely unscientific, we'll just turn them on and press go.

let's check out the obstacle course. first up, we've got some pet hair, and we've trodden that into the carpet. over here, we have soil. over here, a little obstacle — we have a chair. so, let's see if the bots can get under there. and then, a few extras — over here, we have some toys and a phone charger. as one final challenge, we're going to cover the whole course in glitter. whistle. let the challenge begin. and they're off! the eufy has made a beeline for the messiest corner with all the dirt and glitter. we're not testing it here, but this vacuum also has a setting that helps it detect areas that need more suction to clean. and it can mop the floor, too. the suction on the miele looks very strong. this vacuum has two types of attachable arms for cleaning different surfaces, and cameras that help it navigate obstacles.

the irobot maps out the space on its first run around the room, not picking up too much dirt in the process. this vacuum can deposit dust into a bin on the base station. it also uses al to help it avoid obstacles when they're detected through its in—built camera. the proscenic has run into trouble pretty early on. it gobbled them up like pac—man. this vacuum has mopping and dust—collection features. but it wasn't the only one tripped up by the toys. it hasn't actually sucked them up. onwards. the eufy ran into trouble, too. our robot now has a tail. and the miele ran into the same problem. ok, let's take that out. the irobot didn't attempt a full clean until we set up the companion app.

and that is the proscenic heading back to base, and it's taken the charging cable with it, too. come on, give it back. not a very good clean. ok, so the eufy has finished — but there is still a lot of glitter, fur, and mud. and that is the miele done. and, yeah, even though it got caught on pretty much every obstacle we left out here, it has done a very good job of the cleaning. the irobot has gone back to base, and it's taken the charging cable all the way with it. and it's even sent me a photo of the charging cable to the phone to say it detected an obstacle. i can still see a lot of glitter in the corners over there, and a bit of dog hair. now, we're going to pit all the robots against this hand—held dyson. i'm cleaning up really quickly and effectively here. sometimes, if you want a good job doing, it's best to do it yourself. i feel like it was quicker

than using the robot. i didn't get anything tangled up in the obstacles. but my back is sore, so... he laughs. i feel like all the vacuum cleaners actually did a fairly good job at picking up a lot of the dirt. there was always a bit of glitter left over, but these were never going to be as strong as one of these hand—held vacuum cleaners. chris there, proving the robots aren't taking over — unfortunately for his back. and just before we leave you, let's go back to ifa in berlin, where spencer's found a friend? spencer: yeah. do you think she likes me? how could she not? well, as long as she doesn't leak oil on the sofa. and at ifa, there was even something for you if you're one of those old—fashioned types who likes your furry friends to be, er, real. it's a pet dryer. a dryerfor your pets. yeah, i'm not convinced either. but, seeing these crazy ideas on the show floor did give me a warm, fuzzy feeling.

vibrating: ohh... ..that�*s soooo goooood. stop, don't stop. ohh, stop it now. don't stop. look, it's hard work, all right? as i said, you can find everything at ifa, from the frivolous to the much more important. now, if i were to say to you "jabra", you might think headphones and earbuds. that's what the company's normally associated with. but it actually has its origins in hearing aids. and that is what i'm wearing right now. these are the enhance plus, and they are some of the first self—fitting hearing aids, which means you don't need to go to a specialist to get them configured for you. you set them up using a hearing test in the iphone app. and, unusually for self—fitting hearing aids, these let you stream music and calls using bluetooth from your iphone, too. and they're really designed for people who should wear hearing aids, but don't really want to. so, you can wear these out and about, and itjust looks like you're being funky.

ijust wish i'd shaved my ears this morning. now, does everyone want you to be everywhere at once? do you need a virtual customer service assistant who looks a bit more human? i'm having my photo taken... because i'm about to be cloned. this korean company specialises in avatars that speak different languages and perform different gestures on the fly. when you are making a video, you have to hire a model for filming and editing something. it's a whole process. but we can reduce all of that process. all you need is one photo of your face, and the system will map it onto a virtual version of you which can then step in when you're out. it'sjust yourface, mind. you just have to hope that it fits to one of the pre—programmed body types and styles. i'm imagining — it's a dark, rainy night, my car's broken down, and i knock on the front door of the nearest mansion.

and it's opened by that lady. and i just run. the result, i would say, needs more work. robotic voice: now i i have a clone, i can take the rest of the week off. and, while that totally believable version of me fields my calls, i've nipped off to the nearest vr multisensory dome. there's a giant mining truck going by. and, yeah, i canfeel... i can feel it rumbling, thanks to the vest. yes, it's a haptic vest, which vibrates whenever the experience demands a little extra sensation. also... now i'm sitting with a lady on a chair. she's asking me to sniff a piece of chocolate cake. ok, i will. i can certainly smell something — is that chocolate? i think that's probably chocolate. all right, well, i'm having all my senses stimulated here. my nose is being tickled by scents emitted by this smell ball, which only slightly

reminds me of the interrogation droid from star wars. imagine you are in your home or in your office, and then, you put on the vr, you put on the vest, and the wind and the smell, and you have the feeling you're on maldives. she laughs. if you really do need transporting somewhere else, well, here's the city transformer ct—i microcar. an electric vehicle that can change shape to squeeze into tight parking spaces. and for those who have to pull heavy loads around an industrial setting, here's the soflow mover — possibly the coolest way to carry goods around a warehouse. pulsing blue lights are not included. oh, it really has been a wild ride this year. now, there are plenty of

challenges ahead for all of us, so i don't think it's wise to make any predictions at the moment. but i'm sure whatever happens, some entrepreneur somewhere will have an answer for it. and i'm afraid that is it from ifa 2022. it is so. good. to. be. back. keep on saying it, keeps on being true. thanks for watching. we'll see you soon. hello. yesterday was a day of sunshine and showers. today, it's a pretty similar

theme, but if anything, i think more in the way of sunshine and fewer in the way of showers. still quite a cluster around first thing on thursday on the tail end of this weather front that's sliding off towards the continent, but actually this little finger, a brief finger of high pressure is going to try and settle things down for this thursday. so, there's some showers to start the day across the south—west of england and pembrokeshire, gone through the morning, but winds in off the north sea will feed some scattered showers into northern england, the north midlands, perhaps the north of east anglia through the afternoon, a few across scotland, too. but predominantly, i think, dry and sunny and temperatures upa degree or so on wednesday, 15—17. through the evening and overnight, it's going to turn quite chilly across eastern areas of england, winds fall light and the skies stay clear. different picture towards north—west, winds kick up, cloud comes in and rain by the end of the night for northern ireland and western scotland. so, 10—11 the overnight lows here. perhaps the odd three across the south—east of england.

friday, we are going to be dominated by low pressure. we start the day fine with some sunshine across central and eastern england, but wet towards the north—west. and this whole system will swing its way through during the course of the day, brighter but with some showers through the afternoon for scotland and northern ireland. temperatures dipping behind the weather system yet again, and then it's a wet end to the day across eastern england. that whole frontal system, though, does push away quite quickly, and in time for the weekend, we're left with low pressure, yes, but i think more in the way of sunny intervals again. some showers, just the chance of some more persistent rain running into the south of the uk later on on saturday. so, in comparison to friday, well, yes, it's still quite breezy on saturday, but we shouldn't see so much cloud around and outbreaks of rain will come and go rather than being persistent, aside from potentially this area pushing into southern england later on in the day on saturday. and that could linger on overnight saturday into the early part of sunday, too, but sunday daytime, of the two days, perhaps the one offering up less in the way of showers. it's still quite a notable

westerly breeze. our greatest chance of getting caught in the rain will be along many of our west coasts, but in the east, with some shelter, it should feel pretty pleasant again. temperatures getting up into the mid—teens.
