‘ mild spell, ‘mild spell, as chillier. very brief mild spell, as the weather fronts dies off into the continent, taking mild airwith the weather fronts dies off into the continent, taking mild air with it. cold arctic air again for the rest of the week. hello, this is bbc news, the headlines. five people — including three children — have been killed after a stolen car struck a tree in leeds. two boys aged 15 are in custody. the international trade secretary, liam fox, has said the future of the irish border cannot be resolved until the united kingdom and the eu have reached a trade agreement. he ruled out the uk staying in the single market or the customs union. drone users will have to register and sit safety awareness tests as part of plans to regulate their use. the police will also gain new powers to crack down on illegal and irresponsible drone flying. indonesia has issued its highest level aviation warning as a volcano on the island of bali spits out smoke and ash. there are fears that a full—scale eruption of mount agung is imminent. now on bbc news, it's time for click.

this week: fighting fires... naked navigation... and a real—life rocketeer. on click we often look out for technology which can help save people's lives. for example, we went to rwanda to look at how drones were speeding up deliveries of blood and recently closer to home, i looked at how the response times of the air ambulance in london were being improved by better connectivity. if you live in the developed world,

you'll probably take it for granted that you can dial the emergency number, someone will answer and help will arrive. well, in kenya, that's not the case. in the capital nairobi alone, there are more than 50 different numbers for different ambulance services and if you need a fire engine, well, that's at least a dozen more, and even then there is no guarantee they'll be able to get to you. well, kate russell has been to meet a couple of entrepreneurs who have had the great idea of amalgamating them all into one service. think uber for emergency services. for most living in a modern metropolis, calling an ambulance involves dialling a single short code. but in a city more than 6 million people, nairobi has no functioning central emergency number. with five public hospitals and dozens of private hospitals and clinics all operating independently, you have to know

who to call if you need an ambulance here and hope there's someone on duty to pick up. caitlin and maria run a start—up in nairobi hoping to address this problem. you just take for granted 911 exists and we did as well, both of us had lived here for years and we never even considered it and we'd worked in health and i never even thought what i would do in an emergency. we just started asking people, have you seen an ambulance before? who has an ambulance? we would go and meet and find ambulances in parking lots and we started a really simple tally of how many ambulances we could find. we realised there were so many ambulances and nobody has any idea where they are. flare‘s aim is to connect emergency response vehicles on an uber—style platform that can route calls to an operator that can get their quickest. when the call comes in i get to know the patient‘s location, i click on the location.

we can see all the vehicles that are within my range. i can select the ambulance service, which is six minutes away. let's click on the ambulance service i'm going to dispatch, it gives me the contact number and their location and the estimated time. it also gives me the direction route for them. so you've been using this system through states of emergency, for example the first elections. for example we used it for the election of 2017, and we also had a backup for the radios. we had the emergency services covering all the emergency situations... sorry, sorry? leah, emergency! a busy city hospital, we left patrick to his work

and headed out onto the streets to see first—hand the traffic problems that make this kind of operator routeing a lifesaver. this was especially important when violence broke out during the october elections. fla re‘s ambulances were 33% busier attending to emergencies in these hotspots. the response times we've seen have gone down from 162 minutes, which is the average, which is nearly three hours, which is insane, to about 15—20 minutes. so far the platform has 30 ambulances online, with a goal to reach at least 50 by the end of january next year. an annual membership fee gives patients access to the emergency hotline and covers the cost of any callouts, which otherwise would have had to be paid by credit card before an ambulance is dispatched. the fee is currently around $15—$20 but flare say this might change as the service matures.

eventually flare wants to add more concierge—style features for its members, like real—time updates and treatment information. the data being collected might also prove useful to help co—ordinate better service across the city. one of the things we recently learned is there's a lack of ambulances between 7am and 9am and the reason for that is that the night team is handing over to the day team, so all providers are doing that shift change, so there's a delay in that happening so then there aren't enough ambulances online to respond to the emergencies. you can use that information and go to all the providers and say maybe staggeryourtimes, right? completely, or make the handover process more efficient such that that doesn't even occur. fire means even bigger problems for emergency callouts in nairobi. as well as the fractured co—ordination issues seen with ambulances, there is a desperate shortage of both trucks and water supplies. tragedies like this in nairobi's

vast clothes market gikomba are all too common and often left burning for much longer than they should be because of a simple lack of access to resources. 999 goes directly to the police headquarters, the police control room. once you call the police control room they start looking for the nearest ambulance service or the nearest fire service. there's no radio linkage anywhere. the phones they have belong to individuals. the fire and ambulance service are controlled separately by different players. ict fire and rescue is the first firefighting school of its kind in kenya. i went to visit them and got to try out some training. flare is working with the school to add as many firetrucks as possible to their nairobi coverage, as well as locating available public and private water

supplies to add to the map. there are another hydrants in nairobi theoretically, they were planned for, but a lot of the hydrants have been built on top of, so we're serveying nairobi to see where there are publicly available hydrants and where their private hydrants are that we can actually tap into. at this stage it's unclear how the membership funding model will play out for fire cover has callout costs could be radically higher and more variable than ambulance work. flare has high hopes of becoming the 911 call equivalent for the whole of kenya in the future. kate russell in nairobi solving a problem that really need solving. i have to say that's not always the case in the world of technology, take for example smart cities, which we haven't really proved we actually need so far. but authorities in canada have teamed up with a massive tech name

to develop a smart neighbourhood that it says will massively improve sustainability and affordability. paul carter has been to toronto to find out more about google‘s grand designs. google‘s parent company alphabet has its fingers in many technological pies, from home automation, search, life sciences and autonomous vehicles, but now the company has an even bigger idea, it wants to build a whole new city. well, sort of. authorities in ca nada's largest city, toronto, have announced a partnership with google‘s stablemate sidewalk labs to design a new waterfront area known as quayside. sidewalk labs say they want to see a city built from the internet up. what does that look like? streets will come alive with the vitality we expect from sort of the greatest urban environments in a way that has never actually been seen before.

the plans include modular buildings that will automatically adapt to wind and rain, robot delivery services, underground rubbish disposal trains, heated roads to melt the snow, digital navigation systems, smart traffic, self—driving buses. so far, sojetsons, but will any ordinary people actually be able to afford to live there? what's really interesting when you sit down with this and walk people through it is a big part of what they want to do and a big part of these advertisements they present for themselves is this will lower the cost of living. they're trying to find ways to reduce your cost of mobility, so for example you don't actually have to have a car at all. these plans also rely on data and lots of it. sensors in all aspects of the development, buildings, roads, open spaces, will measure how and when people use the environment. in a week when it was revealed android phones were sending location data back to google, should people be concerned

about their privacy? they have a profit motive, they have a business purpose for existence that you have to make sure at all times you safeguard the public interest and that's our job on everything we do. they made it very clear that even though they are part of the alphabet organisation, which includes other technologies like waymo, their driverless car autonomous vehicle, they are under no pressure or no directive from alphabet to have to use their technology. they believe that to fulfil their objectives, they want to get the best in class, the most innovative technologies wherever they may be. both waterfront toronto and sidewalk labs have a year to thrash out the finer details of the plan. any time you do anything complicated, i was deputy mayor of new york for the six years right after 9/11, my response included rebuilding the world trade center site, you're never going to get unanimity, but that's

what the democratic process is all about, putting ideas out there, getting feedback, adjusting them and ultimately hopefully winning over enough people that you can move forward. at the moment, this smart city of the future exists only in drawings and documents. city planners and technologists from around the world will be watching with interest to see if google‘s grand plans ever make it from concept to construction. hello and welcome to the week in tech. it was the week that us prosecutors charged an iranian man with hacking into hbo, leaking scripts for everyone‘s favourite tv show, game of thrones, and demanding over £4 million in ransom. elsewhere, skype disappeared from app stores in china after the government said it did not comply with the local law. the long—running net neutrality

debate took another turn this week as us regulators rolled back the laws that were brought in under president obama. the chairman of the federal communications commission said the changes would stop the federal government micromanaging the internet. critics argue, however, the changes could lead to unequal access to the internet. and humans and machine have once again been pitted against each other, this time in the battle of the drone pilots. researchers at nasa's jet propulsion lab set up a time trial between their artificial intelligence and drone pilot ken loo. loo was the winner when it came to speed but was less consistent overall than the ai system. it wouldn't be click news without a robot. this fine specimen stands and 5ft1 and calls itself t—hr3. the bot is designed to mirror the movements of its human overlord and may one day be used in locations too dangerous for humans. that's all fine until it gets fed up and goes on strike, citing

an inhospitable working environment. earlier in the show, we saw how a smart city can be built from the ground up. but you still need to be able to find your way around it. so i've been looking at some of the latest augmented reality that aims to help. but first, i need to go and find the man who knows all about it. but he's not the only person i'm meeting. hotstepper is a wayfinding app that uses this scantily clad character to guide you to your designated destination. it is doing so by combining ar, geolocation data, and mapping, and while it's not the only app to overlay directions on the real world, it certainly has its unique character. he's just doing a dance for some people that are walking past the pub. you must be luke.

hiya. lara, good to meet you. you too. so why am i following this man around? why have you designed him looking like this? after the year we have had in 2017, i think we all needed some humour so itjust makes it more interesting to get from a to b. there are a lot of navigation apps out there. why are people going to choose this one? some people find maps on their phones quite complicated to use. we have also put in gigantic 3—d arrows at the end of the road so you can follow him and can you also see from the arrows where you want to go. there are some challenges — we don't actually know where a road begins and a pavement stops, so we have to kind of do our best to calculate where we think that is. to make it look as believable as possible, what we're doing is try to find out where we think you are, what the weather is like where you are, so if it's a sunny day or a cloudy day, and then specifically the location of the sun.

and if we can work out where the sun is, we can then render his shadow naturally to where to should be. but when you're not having fun on foot, then maybe you're trying to find a place to leave your car. well, ar measuring app airmeasure are prototyping a function to help you parallel park — not something you would want any inaccuracy on. in the meantime, the app can be used for measuring furniture, creating a floor plan, or seeing how tall you are. but if you are more focused on finding your way around and have taken a shine to hotstepper, just don't lose your friend or you might lose your way. ok, you cannot miss that arrow but where has my man gone? where is he? the way we talk online has changed in the last decade — and i'm not talking about the rise of social networks like facebook and twitter, but the even bigger explosion in mobile messaging apps like whatsapp, line and wechat, depending on where you are in the world. since 2014, we have been using them even more than the big social networks.

and with all of those people spending all that time chatting, rather than browsing, it is not surprising that companies are desperate to talk to us too. and that can only mean one thing — bots. chatbots. and plenty of them. modern bots promise to connect with us and understand us in more natural ways than ever before, and that means they could potentially do more than just sell us stuff. for example, they might even change lives. dave lee has been looking at a unique project in seattle which is using chatbots to help women who are working in the sex industry stay safe. this is aurora avenue in north seattle — a long, straight road full of liquor stores, worn—out car dealerships, and cheap motels. it is known as one of the tracks in the area, and that means it is a popular place where women

would come and be involved in street prostitution and men come to basically drive up and solicit for sex. as day passes into night, we see only a handful of working women walk by. just because this street isn't as busy as it perhaps once was doesn't mean this business has gone away. in fact, it is quite the opposite. the scale of the job to save these women who are now behind closed doors is incredibly overwhelming. like just about every business you can think of, the sex trade is now almost completely online, powered by listings websites which do little to prevent abuses. it makes the women caught up in this dark world much less visible than ever before. i was in the life for ten years. i had a pimp, it was very violent, i had a quota that i had to meet every day. if i didn't make that quota, like, there were punishments for that, you know? i stayed sometimes in hotels

for weeks, months at a time, the same room, not leaving, maybe just to smoke a cigarette or go to the vending machine to get a snack. and those four walls, and i can remember having the tv playing just so there was noise going, right? and i remember sitting in there and feeling that the whole world had forgotten about me. and what would have shifted if i would've looked down on my phone and someone said "hey, this is jackie from rest. i used to be in the life. i have resources. do you want to chat?" real escape from the sex trade, or rest, is a group that seeks out and helps women trapped in the sex industry. this is a centre for those taken out of the life. it is temporary, safe accommodation. the organisation is backing a new initiative, developed with the help of microsoft, that uses chatbot technology to intercept anyone considering buying sex. the team places fake sex ads on popular sites.

when a potential customer texts the number seeking to buy, it's a chatbot that replies. so in this case, we have set up the bot so that is simulating a 15—year—old trafficking victim. this isjust asking me questions. it's saying how old am i, it says $100 an hour, what service am i looking for. we work with survivors of trafficking to ask them how would a conversation like this go? what are the things that you would say? what would be tip—offs to you that this would be maybe not bot but maybe a law enforcement officer. it has told you that it is 15 and says how does that sound to you? and that's where the hammer drops. and here's the message. wow! that's a really shocking feeling for someone who thinks they are anonymous, who thinks that they can go on the internet and buy another human being, it is a big wake—up call. the bot isn't being used to arrest people. instead, it is intended to work as a deterrent. similar artificial intelligence

technology is being used to scrape websites and reach women who may need help. outreach comes via a text message — something that is much easier to hide from a pimp than talking to a charity worker in the street. with text outreach, we can reach so many more individuals on these phone numbers that we are pulling from online ads and when a girl gets a text message, she can respond to it in a time, in a place that is safe for her to do so. impressed with what they've seen so far, law enforcement agencies in seattle are now using the tech with encouraging results. there are thousands of buyers online at any time of the day or night. when we post a fake ad posing as a person in prostitution, we will get 250 responses in the first two hours. there is no way that law enforcement has the capacity to respond to that. a chatbot allows us to connect with and deter all of those buyers online at any time. we've never been able to do that.

yet this issue needs a more permanent solution to stop websites being used to sell sex. that's what is being worked on here at the us senate. it's time to say no more. new anti—sex trafficking measures have bipartisan support here, but some tech companies have raised concerns that the new rules could be too broad. while tech companies and legislators iron out the detail, amanda's work in saving women continues every each day. just yesterday, i had a young woman come up to me who was living in our residential programme. she comes up to me and she's like "amanda! i have a car, i have a licence, i have insurance! like, insurance — legit!" those are the moments that make it more worthwhile and make it seem less overwhelming, because we know we are making a difference. whenjames bond used a jet pack to escape the bad guys in thunderball, the world wentjet pack mad. but the us military—designed

bell rocket belt that he used was later scrapped due to its high price and limited flight time. almost 60 years on, science fiction is finally becoming science fact. several companies, and even individuals around the world, have taken to the skies in recent years to show off their versions of a jet pack. and recently, i was invited to strap myself into one. fortunately, this was only in vr. ok, here we go. we are going to go up. 0k! the real thing has been built and tested by new zealand company martin aircraft, which has now been bought by the kuangchi science company in china. first things first — technically, it isn't a jet pack. it lifts off using two ducted fans which are powered by a petrol engine. it is still in testing but the team hopes that by the time it is ready,

it will be able to fly as fast as a0 kilometres an hour at an altitude of 2,500 feet. on a single tank, it should last for about 30 minutes covering distances of 20 kilometres, carrying about 100 kilos. and kuangchi says it will be used for far more than just fulfilling the dream of human flight. translation: what can we do if there are people stranded in a high—rise fire? this jet pack can reach places where a helicopter cannot. a helicopter requires space but with a jet pack, you can get very near and hose the fire down. martin aircraft has been developing flight technology for over three decades and previously thought it would start selling these by last year. now, the company hopes the chinese financial boost will finally be enough to get it off the ground. back at my vr demo, i am starting to realise i may not be the idealjet pack pilot.

yes, that's quite enough from us for this week's click, but there is plenty more happening on facebook and on twitter. thanks for watching and we will see you soon. hello. some briefly milder but wet and windy weather on the way from the british isles overnight tonight. here is the weather system that will be packing all of that game and we will see the rain and strong winds arriving into northern ireland and scotla nd arriving into northern ireland and scotland soon after dusk. since no also for the scottish mountains. the system clears through to bring heavy

rain into the north—west of england and wales and then will sit across southern england by the end of the night. a much milder night and we are used to recently. could be frost across eastern scotland and the risk of ice. they generally the lively weather will be courtesy of this weather will be courtesy of this weather front. we have weather will be courtesy of this weatherfront. we have seen weather will be courtesy of this weather front. we have seen heavy bursts of rain embedded in it as it stretches across southern england from the morning rush—hour. there could be difficult conditions south of the ma, but temperatures in double figures. some showers for wales and the north—west of england, showers too for northern ireland, and for northern and western scotland, and we could see some wintry ones especially in the north. we will still have a strong wind here as well. that front gets out of the way into the south and the channel by lunchtime. think should brighten by the afternoon. we should continue with showers for northern and western areas. but temperatures in the south in double figures on monday. that is the first time we have seen that in a while and

probably the last time as we look further into the week ahead. that mild weather with this briefly, once that weather frankly is into the continent, we open the doors to the cold aircoming continent, we open the doors to the cold air coming down from the arctic once again for tuesday. there is the weather front plunging into the continent, though pressure to the east, high pressure to the west end straight from north to south the air across the british isles. tuesday, plenty of showers, some significant snow. a lot of winter sunshine however, that it will feel chilly. frosty nights as well, a cold start to wednesday, a chilly start for many. a windy story in the east and afairfew many. a windy story in the east and a fairfew showers many. a windy story in the east and a fair few showers that could be wintry across the higher ground. scattered showers for the south—west of england and wales. the week ahead, briefly milder, but only briefly on monday. then we are back into a cold regime and a biting northerly wind. this is bbc news.
