hello, this is bbc news. the headlines at 3.30pm: a minute's silence has been observed at the notting hill carnival to pay tribute to the victims of grenfell. earlier organisers held a remembrance ceremony to open the festivities. two lorry drivers have been charged with causing death by dangerous driving in connection with a collision on the m1 near milton keynes in which eight were killed. shadow brexit secretary, keir starmer says britain should remain in the single market for ‘as long as necessary‘ after leaving the eu, to avoid the economy falling off a "cliff edge". president trump announces he is to travel to texas, as the remnants of hurricane harvey continue to cause catastrophic flooding across the state. now on bbc news: it's time for click. this week, the second of our repeats from india.

we are hitting the road, the rail and the water. there will be dancing, and singing, sort of. driving in india is an experience. the roads are crammed, the horn is omnipresent, and the rules are... well, the rules are here somewhere, i'm sure of it. and that's why we won't be doing a piece about self—driving cars in india any time soon. despite the fact that it seems

like everyone in india owns a car, that's not true by any means. many people choose to travel by train instead, but if you think that's any less intense, think again. yeah, about those rules... mumbai central station is a massive, heaving hub, connecting the city to the north and east of india, but if you look closely, you'll see something else connecting the commuters to the rest of the world — 116 wireless access points provide free wi—fi to anyone with an indian phone number. it's been provided by google, which, at the moment, says about 2.5 terabytes are being downloaded here every day. and here's the interesting part — this is notjust about this station. along india's railway tracks lie 16,000 kilometres of optic fibre and google is piping internet access down those cables to feed wi—fi

access to 114 other train stations, too. the man overseeing the project is gulzar azad, and i caught up with him while he was waiting for his train. if you had to take one place in the country where you wanted tremendous fibre and you had to have reliable power, relatively speaking, power is a challenge across the country... and you had to have the entire country walking through it. that one place, that's only one place — that's the railway stations. can you guarantee that all services on google's wi—fi will be treated equally? absolutely, i think the whole idea and motivation for us, if you look at the reason why we did this, was to see if we can provide an open internet, completely open, with full access to the entire web, the way the web was designed. so there is a fibre—optic network

that's rolling out from train stations like this to the vast rural areas of this enormous country, and david reid hopped on a train to find out what effect that is having elsewhere in india. it's hard not to be romantic about india's railways. british colonial rulers laid track for control, shifting resources, mostly out, and prising open markets. now it's about moving people, millions a day, and thanks to optic fibre, data. i took the train tojaipur station to investigate. it has proper broadband, and it's free. people are filling their boots.

apart from some controversy at one station where commuters were using the free wi—fi to download hard—core pornography, the provision of high speed wi—fi has been almost universally praised. 90,000 people pass through jaipur station every day. i'm using my wi—fi for entertainment. i find it great. for studentjournalist urja sharma, it means she can keep tabs on breaking stories. every morning, you know, the world changes. there are so many things that change, so i have to come and check. indian stations are full of thriving businesses, feeding off or simply feeding the thousands of people streaming through them every day.

free wi—fi has been a boon to local businesses. ashok runs a tea stall on the station platform, and he's making more money now that his customers can make online payments to him. translation: i use the wi-fi when my ag signal does not catch. when that does not work, i use wi—fi, especially when a customer pays digitally. i need it to confirm i have received the payment. digital payments are worth 40% to 50% of my takings. this is music to the ears of people managing the railways of india, a nationalised industry that runs at a loss. they think that high—speed wi—fi could be a good pull for a station like jaipur. they plan to build a huge concourse and attract retail and service businesses. it mightjust be an earner. as wi—fi expands and it becomes taken for granted, then i think people will transfer more and more of their business.

jaipur is a domestic hub and a tourist hub of high repute. people come out here from all parts of the world. so now when you have a huge concourse, it is an area where you can have shops and entertainment. for google, more people online is more people to sell to. india's railway is the country's backbone. its public wi—fi is poised to be at least as far—reaching. you may have noticed by now that the roads here in india are, well, utter chaos. that's all the more astonishing when you consider that so few people own a car here. there are just 32 motor vehicles per 1,000 people in india. in the united states, there are 797.

but that number is changing, and i'll tell you a secret — it's not going down. looking at these roads, that's a pretty scary thought. one solution could be to make better use of the cars that are already on the road. enter 0la cabs, india's biggest taxi hailing app, orthe uber of india. or as they say... uber is the 0la of india. founded back in 2010, three years before uber launched in india, they have taken full advantage of its head start. 0la have historically been number one in india, but uber has said that that's changing. it looks like the battle for india's cab cash is onlyjust beginning. these are the head offices in the silicon valley

of india, bangalore. this is 0la's employee number one. india is not designed to have many cars, 10% ownership. what are the specific needs of your customers and drivers in india? we made an inclusive platform that is notjust about cabs but about many other things in india. rickshaws and tuk—tuks. .. the buses that we have in a few cities, the minibuses, the bikes, electric rickshaws, etc. so it's an inclusive platform for mobility where you have different platform options at different price points for different uses, so that brings in a lot of options for users. 0la says that it's better because it is local and it knows what works in india. they offer things like walk—in centres for drivers and being the first to allow customers to pay by cash. uber is coming into the indian market. how are you different from uber,

and how will you stay ahead of uber? there is a fundamental difference in the belief of how we operate. we believe in what we want, not what we have, in terms of plugging in things which have worked elsewhere. you need to build it from the ground up. it's about the connection you make. it's not just about the transaction. part of that connection is offering centres like this. here, drivers can talk face—to—face with 0la, for example, when theyjoin the service, for training, or if they have a problem, an issue with their wages, for example. but 0la doesn't actually employ any of these people. 0la calls everybody here a partner. in reality, they're self—employed. that means they don't get things like holiday pay, and they are responsible for maintaining their car and paying for fuel. the flip side is that drivers can,

in theory, set their own schedule and work when they please. it's a controversial system that 0la, uber, and other transport and delivery companies around the world have used to keep costs down. despite this, 0la really, really wants drivers to drive... a lot. so much so that there are carrots if you stay on the road and sticks if you don't. what india really needs to focus on is to enable mobility for a billion people. we need to leapfrog all sorts of impediments and we need to promote shared mobility, sustainable options. 0ur government is focusing in a big way on electric vehicles. the government want all vehicles to be electric by 2025, 2030.

0la is one of the most successful start—ups to come out of india's education system. called indian institutes of technologies, these universities are dotted across india and they are the driving force behind many of the country's technological successes. getting into an iit is a competitive business. only a tiny fraction of applicants get in in any year. but if you do, you get to work in incredible campuses like this. my first appointment is at the olympic—sized swimming pool — although it's not me who's taking a dip. this is matsya, named after the avatar of vishnu which takes the form of a fish — it's a multipurpose underwater robot that can operate autonomously, without a human controller, to locate sounds, and recognise, grab, and manipulate objects. the team tell me it might be used

to find flight recorders from crashed aircraft, although they're also pitching it to the military to fire torpedoes. the project is in its fifth year, and the team leader tells me the work here is hard, but can be massively wide—ranging. "like a racing car, or a satellite." brilliant! matsya is one of 100 projects that have been supported by iit bombay‘s society for innovation & entrepreneurship since 200a. sine is an umbrella for start—ups and, as with incubators everywhere, you'll find all kinds of ideas bubbling away behind its doors. as you might expect, there are aerial ideas,

there are medical ideas, but there are also musical ideas — which is why you find me making strange noises with my face... # doooo—deeee—doooo...# very good. you got some score over here. "some score"! if you do it better, your score will increase. yeah, the worst karaoke india has ever heard. but then, this singing—training app is so much more than normal karaoke—style games. most karaoke apps do a very cursory kind of evaluation of your singing. some of them don't even evaluate the singing, theyjust have some input — you just open your mouth, you get a good rating. what we do is a multidimensional evaluation of your singing on different aspects of music — pitch, rhythm, vibrato, falsetto, dynamics, timing... # eeeehhhh—oooohhhh...#

you asked for a hard exercise! # eeeeeh—eeeeee—eeeeehhh...# echoing if my singing went right through you, i've got something upstairs that will really cut to the bone. the algosurg team are working on a system to help surgeons to plan surgery. they've created software that's learned to create a 3—d model of bones from just two two—dimensional x—rays. i can imagine, after a lot of experience, a bone — if i just look at an x—ray, i can imagine it in 3—d. can we do the same thing with computers? a surgeon can do it, because he has learned a lot of correlation between x—ray image and that 3—d bone which he sees during the surgery. we used the same logic to develop the software. we have a machine—learned algorithm which has learned the 3—d shape of bones across the population. we have created a lot of 3—d

models from ct scans, and we used this as a kind of database, and we create an algorithm to understand that database in a very particular way to predict a 3—d model from an x—ray image. these 3—d models also allow for tools and guides to be designed to the patient‘s specific dimensions. for example, if a surgeon was preparing to cut and realign legs. we have special, specific instrumentation which uses the bone surface in 3—d, and it is like a negative of the 3—d bone surface. if you make that part and print it in 3—d, and put it on the real bone, it will exactly fit in a very unique fashion. so what we do is, we use that concept to cut, to make surgeon cut more accurately, so this part will be exact fit on the bone, but it will also have a slit which will be aligned with the cutting plate. that slit can be used during the surgery to guide a cutting tool.

two x—rays are, of course, cheaper than a full 3—d ct or mri scan and, once again, it means patients can be assessed who can't get to a fully kitted hospital. it's no surprise that many of the projects here concentrate on low—cost, rugged solutions to developing—world problems. you may have come across braille displays before, which allow you to connect via bluetooth to your android tablet, then whichever menu item is highlighted on the screen, the text is mirrored on the braille readout here, and you can control the navigation using up and down buttons here. well, this is a prototype braille display called brailleme, which works in a slightly different way. the braille displays currently existing on the market are based on piezo—electric technology. because of that very thing, the cost of these devices are around $2,000 to $3,000 each. we developed a completely new technology based on magnetics

through which we are able to reduce the cost ten times. we can sell it to the user at a price point around $300 to $1100. this machine needs to work for at least ten million cycles of up—and—down movement, it has to be quiet, low power — all of those features make it very difficult to make such a compact device. so that is the challenge. this is the anjuman urdu primary school in the town of kundapur in karnataka. there are 155 kids here from grades one through to seven, and a whole bunch of dedicated teachers. and this is how they start their day. singing over in vijaya nayak‘s classroom, things are a little more serious.

so, at the back of the projector, there's an android device which is plugged in and is running videos on english, maths and science. the videos are made for the entire region. but then they're dubbed in different dialects, different languages, depending on where they're being sent to. today, we're learning about fractions. it is a great teaching tool — as long as there is electricity. but there are plenty of times when there isn't. translation: this is a village school. earlier, it would be difficult to teach because of power cuts. we would get electricity in the mornings but, as the day passed by in the afternoon, we would have power cuts for more than two hours. that's why the projector and tablet are hooked up to this box, which is itself attached to a solar panel on the roof. together, they can provide up

to five hours of electricity a day, meaning that classes don't have to be interrupted or cancelled if the power cuts out. then, we started using solar power, as it is an easy and natural source of generating electricity. we have introduced a study of generating power through solar energy to our students, and are teaching them the importance and working of it. we also explain to our students that this process will help us, in the future, to generate electricity. this whole system has been provided by the selco foundation, an indian charity with the aim of helping to alleviate poverty by improving access to energy. with this, students can get a better education through audiovisual teaching, and also there is no problem with electricity. so any time the teachers can take their students to the classroom, they can teach through this medium. selco and other ngos they work with pay for half of the cost of installing the projector and solar system —

the other half comes from local schools or local government. how important is the projector? translation: before this project came in to use it, we had very few students. but since we have started using the solar power, our number of students has increased in a good way. we have students coming to us from different villages to learn, and not only students — we have other schools coming down to our institute for smart classes. the smart class is a good way of teaching kids these days. they seem to enjoy and learn more than usual. after we introduced smart class, our school stands proudly in the educational sector. we plan to grow larger as the years pass by. cool whoa! the same system is already in hundreds of rural schools, and they're aiming to add hundreds more this year. and it's notjust key for schools — across rural india, businesses can

be helped massively by having a reliable power supply. somana is a seamstress who lives a short drive from kundapur. she became the main breadwinner for the family after her father was taken ill. the more clothing she can repair, the more she gets paid. with her old, hand—operated sewing machine, she could fix a couple of items a day. but thanks to the solar panels on her roof, her electric machine can whiz through five or six clothes per day. plus, she has a fan, a tv and a light, so she can work earlier and later. 0ne quarter of india's rural population lives below the official poverty line. that's 216 million people whose livelihoods could be improved by the addition of basic facilities like electricity. and, of course, one key way of helping people out of poverty is... education.

it's always such a privilege to come to a place like this and see how the simplest technology can make a world of difference. that's it from india for the moment. you can see plenty of photos and more backstage gossip on twitter — we live at: bbcclick. thanks for watching. see you soon. for many it has been a very sunny sunday. certainly the case in lyme regis earlier today, jostling for

space on the beach, barely a cloud in the sky. a very different story further north and west. lots of cloud across cumbria and scotland, northern ireland and north—western parts of wales. by and large where we have had the sunshine we have seen we have had the sunshine we have seen clearer skies this evening and overnight. cloud continuing to build overnight. cloud continuing to build over northern ireland and scotland, heavy outbreaks of rain, a strengthening breeze, that rain arriving in northern ireland towards dawn. temperatures on a par with last night, 13 to 16 degrees. fairly u nsu btle last night, 13 to 16 degrees. fairly unsubtle tomorrow across northern ireland and scotland, squeezing isobars indicating a strengthening wind and some outbreaks of rain pushing east. fairly unsettled and cold feeling day, lots more cloud across north—west england and west wales. for east wales and much of england, it is dry, plenty of sunshine. could see temperatures up to 28 degrees. a very different feel across scotland and northern ireland, given the strength of the wind and outbreaks of rain. quite cool feel, that rain will clear from

north—western parts of scotland through the day. a cloudy affair across north—western england, maybe the odd spot of rain, further east through east wales and england it is dry and warm, if not hot. plenty of sunshine. highs of 28 degrees potentially. if we do, it will be the warmest late august bank holiday on record. some potentially quite hot conditions here. the rain which has been across northern ireland and scotla nd has been across northern ireland and scotland is associated with this front. as it slips across the country to tuesday it tends to weaken. more cloud, the odd spot of rain across the morning which will ease. fairly cloudy across the country. for most of the country, fresher conditions on tuesday. 15 to 17 degrees for many, still holding onto some warmth in the far south—east. looking ahead into wednesday, we are attacked from two sides by every of low pressure. this one from the atlantic and another across the net continent. that means across the net continent. that means a fairly messy picture. details a

bit tricky at this stage, but lots of cloud around midweek. there will be some outbreaks of rain. temperature wise, probably between 16 and 20 degrees. this is bbc news. the headlines at 11.00: two lorry drivers are charged with dangerous driving offences after the m1 crash in which eight people were killed. a minute's silence has been held at the notting hill carnival in west london to remember the victims of the grenfell tower fire. a shift in brexit policy — labour says britain should stay in the single market and customs union for a period after the leaving the eu. lewis hamilton celebrates his 200th formula one race with victory at the belgian grand prix, halving sebastian vettel‘s championship lead to seven points. and in half an hour on bbc news, join us for weather world.
