Now on bbc news, its time for click. This week, how to hide in hong kong. A new bunch of apples. And dying to save the planet . Try green fashion. 0ther save the planet . Try green fashion. Other colours are available. For the last four months, protesters have in rallying in hong kong. First against a proposed bill that would have allowed the extradition of hong kong residents to the chinese mainland to face criminal trials. But bill has now been withdrawn, but protesters remain on the streets, asking for more demands to be met, including greater democratic freedoms and an enquiry into alleged police brutality. The protests have been watched around the world, with the videos uploaded daily showing highly organised groups. In the airport, on roads, and even in the legislature. But with no clearly structured leadership. This contrasts with the so called umbrella revolution of 2014, a Pro Democracy Movement where individual organisers were targeted and jailed. This time, people are using encrypted messaging apps to organise in a more anonymous way and try to avoid interception by the police. China is a world leader in facial recognition, surveillance and Artificial Intelligence technology. So it is not unthinkable but they have found workarounds to keep an eye on the apps. Danny vincent is in hong kong and he met two protesters who are trying to organise without being identified. A smarter lamppost being kicked to the ground and opened up by protesters. Hong kong Authorities Say they are used for monitoring the weather, pollution and traffic. But protesters say they could have a more sinister purpose, housing a facial recognition camera for monitoring and identifying people taking part in the protests. They sawed it down to see what was inside. They claimed to find computer chips made by Mainland Company linked to surveillance. company linked to surveillancelj think company linked to surveillance. think the guys in the front line that took down but surveillance camera, they understand it might be a Surveillance System but is monitoring its people. They actually might not know the entire Technology Behind it. Lasers are another way protesters are using relatively low tech to the surveillance of the police en masse. The laser pens are used because if you pointed directly ata used because if you pointed directly at a camera it will make the sensor of the camera little bit unstable. It might buy time for us, it might disrupt the police from chasing us. Hong kong has seen months of protests. These protests have not been organised by individuals. They have been organised by tens of thousands of people online and tens of thousands of people have also taken to the streets. Much of the organisation has been done using online forums and encrypted messenger apps like telegram. This it professional and protester asked us it professional and protester asked us to call him tony. He is a member of several groups planning protests over Telegram Group chats. Some of these groups of thousands of members. The last time hong kong has had such large scale protests was during the 0ccupy Central Movement 01 during the 0ccupy Central Movement or the umbrella revolution. That movement had a leader. The government has targeted that organisation afterwards. So this time around, people see that it is safer to participate in this Movement Without identifying themselves. Without telegram, i cant imagine our masses would have co ordinated effectively, feeling secure that the police could not implicate us or prosecute us. Some go to even further levels to protect their digital footprints. Go to even further levels to protect their digitalfootprints. Meet go to even further levels to protect their digital footprints. Meet alex. The film i use isjust a normal android film from samsung that has got retrograde security. Phone. It works as a secondary android. It is behind a primary android system. It is two separate systems. There is a lot of passwords you have to input in order to get into that secondary android. It has military grade protection. It is very difficult for the police to trace me digitally. He suspects the authorities are also becoming increasingly tech savvy. Many have long suspected a loophole in the popular messenger up, which could allow the government to monitor communication despite its encryption. Messenger app. Monitor communication despite its encryption. Messenger app. We suspect the government has been incorporating all the hong kong phone numbers into the telegram, or the Police Force Telegram account, to help them pinpoint which person is involved in that kind of speech 01 is involved in that kind of speech or involved in that conflict. Telegram claims it has now fixed this loophole, but fixed or not, protesters are developing other methods of communication. These include using air drop on iphones and the bridgfy up. Bridgfy uses peer to peer met networking and doesnt use the internet to work. Still, these apps may not be com pletely still, these apps may not be completely surveillance free. Sometimes face to face communication is the only means available. If the internet is not good and it is not feasible for us to grab our phones, it is better to do it in the field. This movement has also become an information war between the protesters and police. Protester scouts take photos of police locations and spread the information online. After more than 15 weeks of protests, this movement shows little sign of slowing down. Hello, and welcome to the week in tech. It was the week that ali barberfounderjack ma tech.

And apple unveiled its new iphone, which is giving some fancy creeps. More from the launch event in a bit. It was also the longest ever road trip by an electric car was completed. Suvs from the shanghai carmaker travelled over 15,000 kilometres from china to germany, a journey which lasted for 53 days, called for 77 recharging stops, and resulted in a Guinness World record. I hope they had toilet breaks. And sticking with motors, one day you may be able to redecorate your own in a jiffy. Thanks to a new colour changing ink from mit, nicknamed photo chrameleon after shape shifting chameleons, this futuristic dye reacts to different lights to produce various hues. And finally, here is a bright idea for a new breed of bot. The 0ssibot is powered and steered by light, thanks to a gel which bends towards and oscillates around sources of elimination. The Energy Efficient contraption could one day allow seafaring vessels to travel long distances without any fuel. Fingers crossed this flip is not a flop. The and so to the steve jobs theatre in cupertino, california, for the apple launch event, whereas expected, the iphone range was announced. These come with multiple cameras, the 11 pro and primax have three, which sees them catching up with android rivals. Pro max. What else, better batteries, a slightly bigger ipad, a bit of an upgrade for the watch, and the pricing for apples new Tv Streaming Service was unveiled, cheaper than netflix at 4. 99 per month. That is in dollars 01 4. 99 per month. That is in dollars or pounds, though many would argue it needs to be cheaper given the comparative lack of content. The event was titled by innovation only but overall there was little to quiet the rumblings over uppers lack of exactly that recently. U nless lack of exactly that recently. Unless you count a slow mo soltis as the Ground Breaking feature of the world has been waiting for. Slo mo slefies. Dave lee was there for us. First question, most important, Slo Mo Selfies. Why . For us. First question, most important, slomo selfies. Why . Good question, spencer. Ithink important, slomo selfies. Why . Good question, spencer. I think the question, spencer. I think the question for many is why not. For People Like Us with short herod might not be so good to do slow, glamorous selfie. But i think there will be the influences out there who will be the influences out there who will be the influences out there who will be very excited by the prospect of having a Slo Mo Selfie just for that added glamour on instagram. And certainly it does not feel like apple is leading the charge these days. I mean, there have been several iphone launches recently where we have said, you know, they are still playing catch up with Companies Like huawei and samsung. think that is true, but i think that is perhaps how apple has been for some time. There has never really been too much of a problem for them, apart from the initial iphone, which changed everything, everything since then has been kind of iterative. The problem will be that if you are a sort of person who, like most normal people, wants to purchase a phone that lasts three or four years, the new iphones do not have 5g. Many people will look at that and think, iam going people will look at that and think, i am going to have 5g. Even if i dont have it today, i might have it ina yearortwo. Dont have it today, i might have it in a year or two. This phone doesnt have 5g. In a year or two. This phone doesnt have 56. London fashion week has kicked off with all its usual glitz and glamour, and as the biggest designers take centre stage to showcase their latest creations and set this years trends, protesters from Extinction Rebellion gathered outside to remind the world about the true cost of fast fashion. 80 billion pieces of clothing are produced every year. And many of those are discarded not long after they have been bought. The true cost of fast fashion is now becoming apparent. The industry is now one of the largest polluters in the world, right up there with oil and agriculture. And cotton production isa agriculture. And cotton production is a big part of its Carbon Footprint. Almost half of all clothing contains cotton. Well, Lara Lewington has been to sweden to see a facility which is hoping to refashion our cotton garments several times over. From the cotton fields to the clothes rail, it takes 20,000 litres of water to make just one kilogram of cotton. And to put that into context, that is enough for a t shirt and a pair ofjeans. And that is why what is going on here is so important. At this swedish recycling mill, a fifth of that water is needed to create a comparable amount of fabric. The place runs on wind underwater power, converting cotton into viscose in a process classed as climate positive. Wind and water. These bales are stuffed full of denim, and these case leg panels from pairs ofjeans. So although this facility could separate any metal fastening or even any stitching which is made out of something that isnt cotton, he had dispatch has arrived or sorted already. All sorted. But here, and eco friendly chemical process is followed by de dyeing the fabric. Any remaining colour is been removed through chlorine free bleaching. Watered and transports this pulp into the next stage, where it will be dried for transportation. Resulting in quite literally a blank ca nvas to resulting in quite literally a blank canvas to be sold on to Clothing Companies. And this is the end result. A sheet of what is known as circular s, a type of dissolving pulp. Circular s, a type of dissolving pulp circular s, a type of dissolving pulp. Circulose. That gets sold on and turned into thread which feels a bit like cotton wool, and from there of course it is used to make loading. s clothing. Feels pretty nice. But is now made out of viscose and it is recyclable again, about five or six times. This was in 2014. Four years down the line, this facility was ready to be opened. We can produce 7000 tons per year, annually, of this dissolving pulp, and that equals the weight of 30 million t shirts. We are the First Company which is doing this on an industrial scale. We are not just producing this on an industrial scale. We are notjust producing kilos, we are producing times of this, and that is very important for the industry tons of this, and that is very important for the industry, to realise that this can be done on a realise that this can be done on a real scale, and make a real difference. Because as soon as you talk about kilos, nobody can make a change with a few kilos, but you can make a change with thousands of tons of material, and you can show the world but it is actually working. Raw materials being sorted is just one piece of the puzzle. This denim had to be shipped from the us, although with the scale, more facilities could open worldwide, reducing the Carbon Footprint of that element. And how about the labour afterwards . That is not in this company was in agreement, but it is of course part of the bigger picture. Companys remit. Meantime, high street retailer h m, one investor in the company, will soon have clothing originating from this process on the shop floors. But the big here is that by 2030 the clothing industry might use 100 recycled or sustainably sourced materials. And while that may sound unachievable now, clearly times and attitudes are changing. That was la ra attitudes are changing. That was lara in sweden. So recycling Raw Materials will undoubtedly be part ofa materials will undoubtedly be part of a greener future for the fashion industry. But in the meantime, how about this . It looks and feels like about this . It looks and feels like a thin cotton t shirt, but this is actually made from algae and wood pulp. The print is 100 algae, and the material is made of trees and linen from plants. Pretty co mforta ble, linen from plants. Pretty comfortable, i have to say. Make our instructions are a little bit fiddly, basically keep it cold and dont iron the algae. But the most interesting thing is, when you have finished with it and you want to get rid of it, you can bury it in the garden and it will be gone within three months. Something that is even more harmful to the environment than growing cotton is dying textiles. Half1 trillion gallons of freshwater are used in textile dies each year, the untreated wastewater from the dye is often discharged into rivers, leaving entire communities with no access to clean water, killing aquatic life, and eventually reaching the sea. And get this it can take about 150 litres of water to diejust one can take about 150 litres of water to die just one kilogram can take about 150 litres of water to diejust one kilogram of can take about 150 litres of water to die just one kilogram of cotton. Well, lj reg has visited a lab in london which is only using 200 millilitres of water to die a one kilogram piece of silk. So what is the secret . This lab houses a fashion scientist who uses petri dishes to make carolling colour including more environmentally friendly. This could be the future of fashion, and it smells like beetroot. These beautiful designs were created by bacterial activity, no chemicals required. So how did you come across using bacteria to die clothing . So when i was studying material. I met professorjohn ward here and he introduced me to a particular bacterium, depending on how it is grown, and the environment, we can produce Something Like a navy blue, bright pink, so we use all of these conditions as a design tool kit to influence our patterns and outcomes on the textile. The bacterium ferments in a small amount of sugar solution which produces pigment directly onto fabric as a colony of microorganisms grow. Like a brewery with yeast, the growing conditions are engineered to produce different varieties of colour. I am really interested in how technology is changing, how we design and fabricate our environment, and especially in the context of Climate Change and our resources and the impact they have on the environment. So the imperative for us right now is to try and find ways to change the way in which we process and manufacture textiles, reduce water use, do away with the need for chemicals at the beginning, at the end of the stage. The process is simple enough that even i could get a start on creating my own microscopic civilisation. So satisfying laughs . In that year. Wow there you go, my first, kind of culture . Wow there you go, my first, kind of culture . It is a cell culture. We are going to ferment this now for approximately seven days. Right. And we should, at the end of it, have something that looks a little bit more like this. It is a slow and thoughtful process, it takes a week for the bacteria to transform plain power plain fabric into a kaleidoscope of colours, and it works. 0n kaleidoscope of colours, and it works. On a small scale. kaleidoscope of colours, and it works. On a small scale. I think the challenges are to then take it from a lab scale and then develop it into really large scale a lab scale and then develop it into really la rge scale processes that both work efficiently, but also at the right kind of cost. As well as these unique organic patterns, the technique could also block my fabric a uniform colour, but could these tiny microorganisms make a big enough impact on an industrial level . I am all for it, the Innovative Element we are exploring, i think it is vital, it is crucial, but it has to happen in parallel with behavioural change. Should we be consuming as much as we are consuming . Perhaps not. Ithink be consuming as much as we are consuming . Perhaps not. I think for us consuming . Perhaps not. I think for us it is a 2 pronged approach. Consuming . Perhaps not. I think for us it is a 2pronged approach. And this might help the fashion industry start to get a bit more down to earth. Brilliant, that was lj. Meanwhile, i am visiting London College of fashion to see a very strange catwalk. I am looking at three identical ladies, each one is sporting a different piece of streetwea r. Sporting a different piece of streetwear. And it really feels like they are in the room with me. I am wearing the magical eat mixed reality goggles, which overlay computer images onto the real world. Magic leap. The college wants to explore how we might one day use mixed reality to enhance our Online Shopping experiences pop this app was the result. This is really so much better than looking at photos of clothing on a website. You really get a sense for how the material hangs and the quality of the fabric. Return rates for Online Shopping are over 60 , so the possibility of trying clothes on virtually before you physically have to do that will make a huge difference to consumer experience. This could certainly be a better way for shopping for clothes online, of course what would be good is if it wasnt an avatar of martina here wearing the clothes, but an avatar of me. Which is why i find myself wearing the brightest and tightest clothes while my curves are being scanned by a phone. Capturing 3d content for fashion in the past was either incredibly difficult, with hours spent in front ofa difficult, with hours spent in front of a computer 3d modelling, or very expensive using vast camera arrays. What we are beginning to get towards is the possibility of capturing photorealistic avatars through a smart phone. You do still have to stand absolutely still for several minutes, all the time remembering what mum used to say, blue and green should never be seen. And there is several hours of online, but finally, here i am. The same method is also used to capture clothing items. The idea is that Clothing Companies will scan all their garments in all different sizes, which you can then pop onto your digital double. The team here think this application will go far beyond Online Shopping. They are looking to a time when we will all have a presence in the digital world, and will want our avatars to meet each other looking their best. And not only might there be a market for these completely virtual outfits, one day we might also be able to augment our actual close back in the real world. Clothes. Augment our actual close back in the realworld. Clothes. We truly believe in what is called the ar cloud, is a digital layer across the real world. Where there will be different experiences that you can begin to have, and one of those will begin to have, and one of those will be fashion. There will be digital clothing, and certainly from smart phones, we are able to have depth sensors, track the body to a much more precise level, we can overlay digital garments on to what we are currently wearing, the possibility is absolutely realistic and we believe we will get there. And those who would like to see me in the hoodie next week . Programme, vote now on youtube, facebook, instagram and twitter. Its not going to happen. Thats it for now, thanks for watching and we will see you soon. Hello there. The kind of weather you should expect this weekend depends very much upon where you are going to be spending it. The further south you are across the uk, you can expect plenty of sunshine, it will be dry and it will turn warmer. The further north you are across the uk, there will be some outbreaks of rain at times, not all the time, it will feel a bit cooler and it will be windy, particularly across the far north of scotland. Because low pressure will be trying to muscle its way in here, quite a deep area of low pressure with a set of frontal systems, down towards the south though, High Pressure will hold on, giving a lot of dry weather. Underneath that high, quite a cool start to saturday morning in fact one of two spots in the countryside hovering around two or three degrees. Further north and west, Northern Ireland and scotland not so chilly to start the day, because more of a breeze will be blowing, we will see more cloud, some outbreaks of rain, particularly across the far north of scotland where it will be very windy through the day. Further south across england and wales, once any early mist has cleared, you can expect a lot of sunshine and those temperatures not doing badly at all for this time of year, 23 24 in the south east, 16 19 for scotland and Northern Ireland, which is still not bad by any stretch. In to saturday night, some pretty windy weather across the far north, in fact for shetland we could see gusts of 60 70 mph, maybe a touch stronger than that, at the same time this band of cloud and increasingly patchy rain will be sinking southwards across scotland, Northern Ireland down into northern england, to the south about some clear spells and generally speaking not quite such a chilly start to sunday morning. Sundays weather will be split essentially by this frontal system here. This will wriggle around through the day, there is a bit of uncertainty about exactly where its wriggles will take it, but it looks like we will see some cloud and rain for Northern Ireland, that rain fringing into southern scotland at times, perhaps getting as far south as the north midlands and north wales. To the north of that we will see some spells of sunshine, but again a brisk wind across northern scotland and a rather cool feel to the weather, 15 in aberdeen, but to the south of that frontal system, it will be pretty warm. 25, maybe 26 with a lot of sunshine. As you go through sunday night into monday, that front, weakening feature, will push away southwards, Building Back in from the south west, but that brings us a flow of air from the north or the north west, so generally speaking as we head into next week, things are going to feel rather cool. There will be a lot of dry weather, one or two showers here and there, but those temperatures around the high teens or low 20s at best. Welcome to bbc news. Im maryam moshiri.
