this is bbc news, the headlines: hurricane fiona has ripped through canada's eastern seaboard after making landfall in nova scotia. torrential rain and winds of up to one hundred and sixty kilometeres an hour, caused exstensive flooding and mudslides. numerous coastal homes have been swept into the sea violent anti—government protests have continued in in iran. police have arrested more than 700 people and at least 35 people

have been killed. the protests were triggered by the death in custody of a young woman who'd been detained for breaching rules on dress code. 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 has been to the british seaside. not on holiday, though. i have 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 the 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 in mid—summer. i'd say 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 arc, 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 the 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 fair post—pandemic. i mean, would

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

to grips with the supply chain issues, component shortages is 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 we are a bit short of money...and energy. around ten halls�* worth of ifa were dedicated to the smart home, which traditionally gas meant plugging in bits of your life that didn't previously need to be plugged in. and that's why many of the big names here were keen to attach a particular word to the product. 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 to control the climate. when the window is open, it automatically sends a message to the smart phone 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 come here on an aeroplane, we're all sitting in air—conditioned buildings. 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 ecoflo delta which consists of this solar panel here and one of these three boxes. what's interesting is on a bright, sunny day, the solar panels can charge this box here in about four hours and give you 3600 watt hours, which means you can keep yourfridge 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, right, of higher energy costs, everywhere of energy and security, so in a lot of regions in the world, power isn't a very secure a feature, you have outages a lot, you have prices everywhere in the world, so it more and more it becomes, let's say, consumers and people start to think, "0k, what other way do

i have to have my own secure power generation, independently from any grid, from any provider?" so you could keep your essentials going for a few hours during a blackout, but with a maximum output of 1800 watts, you could blow it all — literally — on some high—powered necessities. just don't get these two the wrong way round. i bet that's the closest you've been to either of those two tools. you know me too well. we will 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? yeah, i've been to dorset, which is beautiful and hopefully 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 is 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 needed 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 current, wave height and tidal conditions. and that's all fed back to shore, with speeds claimed to be 8,000 times faster than current technology used out of sea. it's so vital, it enables real—time decision—making. so any changes or sudden changes in the weather, be — notified, and people are kept up to date to help keep safe, and make sure 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. add 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 rate and saying, "is the seaweed developing at the rate we would expect it to?" and 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 like the sea temperature, the sea state, wave height to connected signs. the whole point really is to give people a now—cast rather than a forecast of what conditions are like in the water. the connected signs 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, 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 also using 56 technologies to connect sensors along the jurassic coast. it's a very unstable, it erodes quite quickly. that's what makes it so stunningly beautiful. if we can use that 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, that data, 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—0ctober 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 will find all sorts, big and small, weird and wonderful, and while there was not a lot that was brand, brand—new this year, we were able to check in on some technologies we have had our eyes on for a while. we have seen glasses like these get better and better over the years. i'm currently playing a playstation 5 game. it's completely taking over my vision so i cannot see you but if i want to see what is going around, i can go full sci—fi bug eye.

this is not augmented reality, no motion tracking, so i cannot 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 usbc cable, so i am off for a drive! yet, over time, you will see previously groundbreaking technology becoming mainstream at these events. you mayjust come across the next big thing, too, if you walk the floors for long enough. mind you, they are darn clean floors these days! this is what happens when these things breed! look, they are all over the place! but how do the latest robot vacuums shape up? time to compare some of the best. here is chris fox with a �*sweeping' review! rock music.

welcome to top of the bots! we're putting four robot vacuum cleaner 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 will 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 are only planning to test their most basic functions. completely unscientifically, we willjust turn them on and press go! let's check out the obstacle course. first up we have some pet hair and we've trodden that into the carpet.

over here, we have soil. over here, a little obstacle, a chair, and we will see if the bots will get under there. and then a few extras over here, some toys and a phone charger. as one final challenge, we will cover the whole course in glitter! chimes. let the challenge begin! and they are off! the eufy has made a beeline for the messiest corner with dirt and glitter. we are 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 section on the miele looks very strong. this vacuum has two types of attachable arms for cleaning different services and cameras that help 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 are detected through its inbuilt 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. 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 did not attempt a full clean until we set up the companion app. and that is the proscenic heading back to base, and it's taking the charging

cable with it, too. come on, give it back! not a very good clean. ok, so the eufy has finished but there still is a lot of glitter, fur and mud. and that is the miele done and even though it got caught on pretty much every obstacle we left out here, it has done a very good job of cleaning. the irobot has gone back to base and it has taken the charging cable all the way with it, and even sent me a photo of the charging cable to the phone, to say it detected an obstacle. you can see a lot of glitter in the corners over there, and a bit of dog hair. rock music. 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 is best to do it yourself! i feel like it was quicker than using the robots. i didn't get anything tangled up in the obstacles but my back is sore! rock music.

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 are not taking over, unfortunately for his back! just before we leave you, let's go back to ifa, in berlin, where spencer has found a friend? 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 to you if you are one of those old—fashioned types who likes your furry very friends to be...er...real! it is 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. ahhhhh, that is soooo good!

stop, don't stop! stop it now, don't stop! look, it is hard work, alright? as i said, you can find everything at ifa, from the frivolous to the much more important. if i were to say to you jabra, you might think earphones 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, meaning you don't have to go to a specialist to get them configured for you. you set them up using a hearing test in the my phone app and, unusually for self—fitting hearing aids, these let you stream music and calls using your bluetooth from your iphone, too. they are designed for people who should wear hearing aids but don't really want to. so you wear these out and about

and it looks like you are being funky. just wish i had 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 specialising avatars that speak different languages and perform different gestures on the fly. when you are making a video, you have to hire a model, and do the filming and editing. now 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 are out. it isjust yourface. mind, you just have to hope that it fits to one of the preprogrammed body types and styles. i am imagining it is a dark, rainy night. my car has broken down and i knock on the front door of the nearest mansion and it is opened by that lady, and ijust run! the result, i would

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

reminds me of the interrogation in starwars. imagine you are home or the office any put on the vr ads you have the wind and the smell and you have the feeling you are in the maldives. if you really do need transporting somewhere else, here is the city transformer cti micro car, 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 is 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 is 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. i keep on saying it, keeps on being true. thank you for watching. we will see you soon. hello. it's set to get colder for all of us over the next few days, although that said, lowest temperatures likely

to be sunday morning. with light winds, we could see a touch of frost in some rural parts to begin the day, a few mist and fog patches, too. they will quickly clear and for most, a chilly start to sunday but a lovely, sunny one. isolated shower, too, over norfolk and suffolk, the channel islands, and as cloud builds in the north and west through the days, a few showers will crop up. most, though, will be dry. the exception as the winds strengthen will be the north—west of scotland — a band of heavy rain quickly sweeping across these areas by the end of the afternoon. temperatures for all down on what we've seen through recent days, aided and abetted by that strengthening wind. those winds will go north—westerly as we go into sunday evening. that band of rain through the evening, scotland, northern ireland, pushes through quite quickly, then clear skies and showers, and then that rain spreads its way southwards across much of england and wales, too, into monday morning. now, it's actually going to be very cold on monday morning but it probably won't feel as chillyjust because of the strength of the wind, and that wind will be a key feature because as we go into monday and, indeed, tuesday, it's coming down from the north and north—west, feeding with it the air that's come all the way from the arctic.

you've got to remember it's september, so in the sunnier moments, it probably won't feel too bad out there but when you're in the showers — and there should be plenty around on monday — it will feel distinctly chilly. those showers spreading southwards and eastwards across the country quite rapidly, so ever—changing skies. early rain on the south coast clears to allow a sunnier day but around the coasts, it's where we'll see some of the strongest of the winds, gusting 40, maybe 50 mph, and that will make it feel colder than these temperatures suggest. just note on the thermometers — only around nine degrees in aberdeen. it will feel even colder than that. a chilly day to come on tuesday as well. a slight shift in wind direction means some eastern areas of england will have a much brighter day. showers in the north and the west, maybe some longer spells of rain sliding through ireland, clipping south—west wales and in towards cornwall. temperatures here maybe up to around 15—16 degrees but only around 10—14 degrees for many on tuesday. a chilly night will follow. rain towards that south—west corner will clear and winds will fall lighter for wednesday and thursday as the area of low pressure gradually pulls away. but it's still going to be

on the chilly side — temperatures only in the teens and there will be some further rain at times, too, before the winds strengthen later on friday. see you later.

had our eyes on for a while.

this is bbc world news. our top stories: knocking. eyewitnesses say armed soldiers are going door—to—door in occupied parts of ukraine to collect votes for so—called referendums minister.
