one feeling a bit overwhelmed by all of this ai a bit overwhelmed by all of this a! stuff. let's take it one step at a time. ok, let's. i'm at ifa in berlin. it's europe's biggest tech show. where in hall 20, the robots are doing their thing, whatever that thing actually is. ifeel like i'm about to have my brain operated on or something. the lasers are going to come out and suddenly, it's going to yank the top of my head off and do some kind of minority report stuff. it's notjust the bots, though — every type of tech is here for every part of our lives. it is a real spectacle with attention—grabbing booths, gravity—defying demos and any attempt possible to make the hottest tech look extremely cool. it's definitely one of the more colourful shows that i get to go to. more of the rainbow next year, though, please — just a personal request there — but it's maybe the white goods that have the biggest outing here. home appliances are well represented and this is a place where they deliberately break an egg on yourfloor so they can vacuum it up again. eh, sticky roller, though. tell you what else is cracking — tv screens. not literally, mind you, but the latest oled tvs are big, bright and sharp and they also turn up in the most unusual places. this could get in the way of shaving, if you ask me. from the bathroom to the bedroom, there is something weird lurking around every corner and if it's your kind of thing, then this place can be fun for all the family. oops! that's what ifa is. but what ifa isn't is a place where you are guaranteed to see the next big thing. certainly don't come to ifa expecting there to be new ideas and new inventions on every single stall. i mean, they are here, but you have to know where to look. this is as much about manufacturers and retailers selling their version of the latest tv or vacuum cleaner or toothbrush or toy or washing machine. but one thing you can do at shows like this is take the temperature and spot the trends. what is everyone talking about this year? and the new boss of the show was in no doubt about the big talking points for 2023. there's two themes that've completely blown everything else out of the water. they've almost kind of zoomed out of nowhere, if you like. ai. you know, if we're being honest, nobody was talking about a! a year ago. now, everybody�*s grandmother is an expert, right? we're in the sustainability village, which is the, you know, physical embodiment, if you like, of the fact that everybody is talking about eco sustainability, energy uses on your washing machine, power. of course, it's easy to say you're green, but harder to live up to that branding. we'll visit one of ifa's more sustainable stands later in the programme. but that other theme — ai — is also something that seems to creep in to lots of product slogans. a! has been in a lot of stuff for a long time. yes. how is it manifesting itself here this year in a way it hasn't before? yeah, well, i would say potentially, it hasn't yet. right. i think where it gets relevant probably for the next year or two and then going forward for our large clients — your samsung's and bosch, siemens, miller miele and those people — they've been talking about smart things in the smart future and that has been taking off a bit slower than they would like to. when proper intelligence gets into your machines and they can really start to influence your life, and i think you will see the hardware reallyjump. and i think there's going to be some revolutions in the home that happen once the power and the capability of a! really gets understood and built into the software and then, the hardware of some of our home appliances. and after spending a little while with desdemona here, i am actually starting to believe that smart appliances of the future really could add at least a little personality to our homes. what can you tell me about the presenter of bbc click? they say the presenter of bbc click is an expert on all things tech and ai—related. i can only assume they must be a robot like me. laughter. and we will be back at ifa soon. one of the things that make travelling to berlin so memorable, for me at least, is, weirdly, it's airport. it was called tegel and it was really unusual. the architecture was pretty brutalist and its layout was like nothing i've seen anywhere else in the world and when it was replaced just a couple of years ago by a more modern airport, it made me a bit sad, really. but tegel lives on. plans are under way to turn it into a tech hub and alasdair keane has been airside. this was, for decades, berlin's gateway to the world. transporting millions of passengers every year to and from the german capital. until demand finally outgrew what its 70s chic could offer. when berlin's tegel airport closed in 2020, there was one big question — what to do with such a huge site? answer, as they sought technology companies, university and even the homes of the future, let's take a look. where better to start a tour than the highest spot? tell us about tegel airport. well, yeah, it is a true panoramic experience. what we can see really well from up here is actually the former orange heike —— cargo holds that the formal workshops will be have the first community of start—ups already here. they do autonomous driving, all sorts of urban tech innovations, yeah, they

september. ifa is full of strange sites, so of course there is the occasional fashion show with... what are those, handbags? no, not handbags. it is a phone. of course it is. this is the honour the purse which is taking wearable tech to the extreme. it is a foldable with screens on the outside, both sides as you can see and it comes with an attachment allowing you to carry it with pride. this is obviously mainly aimed at women plus anyone for whom pockets about a dream or whom pockets about a dream or who likes matching accessories. it comes with customisable characters to complement your coat your, which thanks to the phone's motion and touch sensors can jangle about like a charm bracelet, fluff like love or swim away like any fish in a handbag would. this is what they call a concept launch, to get feedback from the market at this stage but the honour on sale already in china is the magic v2. it is the more traditional model but has no strap. the interesting thing from a technology point of view is that the honour foldable phones are very thin. this is something that we got used to with traditional so—called candy bar phones but when you fold a foldable it necessarily becomes twice as thick. but look at this. this is a reasonably recent traditional phone, and thickness wise, they are... almost on a path. and the reason these can be this thenis the reason these can be this then is because of the battery. it is a variation on the traditional lithium ion battery, and it is already in use in electric cars. it uses a specific mix of silicon in certain parts of the battery, and this gives it nearly 13% more energy density. meaning you get more charge in the same space, or hear the same charge in a smaller one.— in a smaller one. typically you have the iphone _

u.s.—based companies. this u.s. —based companies. this famously u.s.—based companies. this famously meant its phones could no longer carry official google apps. effectively killing their appeal to a lot of the world. but in 2020, honour was spun off as a separate company, so although its phones are still made in china it now has no connection to highway and that means among other things, all the phones now have access to google services once more. —— huawei. how important is it to have google services on your phone? have google services on your hone? ~ ., ~' have google services on your hone?

~ ., ., ., , ., ecosystem. we are at a stage where every _ ecosystem. we are at a stage where every phone _ ecosystem. we are at a stage where every phone maker i ecosystem. we are at a stage where every phone maker is i where every phone maker is struggling to find a point of difference. that's why there is a lot of foldable action these days. new battery technology also feels like a significant selling points. phones as purses? it may not be everyone's bag, but who knows. now, as we said earlier, although whitegoods are ifa's big thing, one of its big themes is green. sustainability was a big theme last year. of course it's a big theme this year and it's only going to get bigger until we solve the problem. the question is, are we any closer to that? as we know, the whole purpose of tech fairs like ifa is for companies to sell brand—new products. it's an industry that is heavily led by new versions — new versions of phones, for instance. we are being made like made to feel very negatively about ourselves that you know, we just don't belong and we're not as cool or as amazing if we don't have all these gadgets. and that is something that i really had to put to the managing director of this massive new tech trade show that we happen to be at. we can be very sustainable by not buying new stuff. and yet here we are at a trade show full of new stuff. so, yeah, how do we balance those two? we obviously have got customers spanning the whole gamut of, let's say, durability and reliability. a lot of our customers pride themselves in the fact that their products are going to last a long time. i think are more enlightened customers realise that they're not really in a battle about, is it... have we shifted 1.2 million units this year versus 1.1? they're really in a battle for brand love. if you've got somebody that's so in love with your product they're willing to repair it and tie up with elastic bands and reuse it as much as possible, that's worth, rather than going and looking on the market again and potentially going to a competitor that's worth just as much. so i think that kind of re—use and repair can have an impact. and so it was that in a tiny corner of ifa's so—called sustainability village, a small group of volunteers were asked here to encourage visitors to make do and mend. it's working. it's working! it's working. ingo used to be an electrician and when he retired, he occupied himself by fixing everything at home. then he set up his own repair cafe where volunteers breathe new life into broken electronics. in germany, the awareness of longevity of articles is growing, and of repairability. people want to repair. the younger generation is rather looking for latest technology, latest design and rather prefers to buy new. i'm not criticising that, but i'm saying in terms of interest in repairing something, it's more prone in the older generation. have you repaired many things while you've been here? actually, five or six only. who comes to an exhibition with a broken vacuum cleaner? laughs there might not be any vacuum cleaners so far, but sebastian has brought his mother's blood pressure monitor. it has brought his mother's blood pressure monitor.— pressure monitor. it didn't compress _ pressure monitor. it didn't compress the _ pressure monitor. it didn't compress the arm - pressure monitor. it didn't i compress the arm anymore. we decided to buy a new one and it wasn't that reliable. so my mother trusted in this device and she wanted this to be prepared. —— repaired. and luckily i found this place where they found the right solution. so she will be happy, the environment will be happy. so another happy customer. but there is a reason that the repair cafe is run by volunteers. the labour cost of repairing these small items means that operations like this aren't usually commercially viable. this is an item of e20. the phone is an item of e6—800. but they're difficult to repair. they are difficult to repair, but they're... if you then spend e30 to open the unit, you can say, yeah, this is worth it, i want to keep my phone. for this unit, it's not worth it because it's more than the new one. so we have we're in this niche where the professional shops cannot really help. but in the future, legislation could help make it easier and cheaper to fix our goods than it is to buy new ones. in march this year, the eu proposed a law that requires more products to be more easily repairable, even after their warranty has expired. and some european countries are already trying to encourage repair. france is leading the way quite a bit there. they have got this very interesting repairability index, showing, with a figure from 1 to 10 how repairable your product is. as a citizen, you can think, "do i want this because it's only a one?" or "do i think i'm going to go for the other one that's "a lot more repairable, which will make it last longer "and be more worth my money?" i think there's a lot that we can do ourselves to make choices that are actually more beneficial for ourselves, especially in times when life is just expensive. i think we tend to think of it short—term in terms of investment and living more sustainably. but if we think about it a bit more long—term, thatis about it a bit more long—term, that is much more in our own advantage, paying a bit more for higher quality can be a lot less expensive. a laptop is better than a desktop because it is smaller, so it uses less material unless impact. also it will use less of your energy. whether tech companies do give us more sustainable products may be a reflection on how much pressure we and governments put on them. and given the importance of repair, i wonder if these guys will be given a bigger stall at ifa next year. and that is it from us at ifa 2023. we will be back for this show�*s 100 anniversary next year. can't wait! meantime, thanks for watching and we will see you soon. hi there. for many, this weekend is going to be hot and humid again, especially for england and wales, with temperatures only slowly coming down across scotland and northern ireland. and as the cooler air starts to invade in there, we're likely to see increasing chance of thundery downpours, some of which could be quite heavy in places. certainly england and wales on sunday. now we've had some cloud drifting up from the south as we move into the early part of saturday, some mist and low cloud around some coasts of south west england and wales. and it's here where we could see some showers or some thunderstorms, same too, across the north and the west of scotland. but elsewhere, it's a dry and a clear night. and again, another very warm and muggy one to start saturday morning with temperatures no lower than around 18 or 19 in one or two spots. so it's a very warm start to saturday, pretty much from the word go. we'll have sunshine around, but well, this weather front will be pushing into the north west of scotland, bringing thicker cloud breeze, outbreaks of rain, a few showers elsewhere. and there will be some scattered thundery showers developing across england and wales as we see temperatures peak at around 32 or 33 degrees in the southeast. so this could be the hottest day of the heatwave. but these showers and thunderstorms, although well scattered, could be pretty intense if you catch one and there's a chance of some localised flooding as well. but most places will be dry to take us into saturday evening. we could see further clusters of showers and thunderstorms running up from the south. again, it's going to be a warm and a muggy night, especially so for england and wales with temperatures beginning to come down across the north—west. now the great north run on sunday across north—east england looks pretty decent actually, although there will be some rain around. some of it could be thundery. these temperatures will be pretty comfortable for running in, but we could start off with some thundery rain in the morning and then into the afternoon. heavy showers could develop with a bit of sunshine in between. but sunday is another warm and humid one for england and wales, with a scattering of thunderstorms developing into the afternoon. temperatures again up to 30 degrees in the south—east, but you'll notice the low 20s for scotland and northern ireland. so things are turning cooler and the trend as we head into next week is for this cooler, fresher, less humid air to spread southwards across the country. and that'll introduce north—westerly winds and also plenty of showers, particularly in the north and the west. it'll be much cooler by day, much fresher at night, but still some good spells of sunshine across the south.
