street. as you expect, many down the street. as you expect, many people have, from across the capital and the country and indeed the world for the carnival 2017. i want to talk to two people who have come all the way from australia. hello. you came from australia, why have you come here today? i was here last year. i had to experience it again. it was amazing. really colourful. your first carnival ever, just ascribed to those who are watching at home the amazon are here today. incredible. i cannot believe it. at home the amazon are here today. incredible. icannot believe it. no words. enjoy the rest of your time. thank you so much. i have been coming since1973. i have been coming since 1973. my goodness, this year is unlike any

other. it is a wonderful day. the past previous years it has been a bit damp and drizzly but today is a gorgeous day. and obviously i am taking part, wearing green. even down to my shorts! they are green, as well. enjoy the rest of today. thank you so much. there you go. people are here to have a good time. as you can see, the procession is well under way. we will have more later on. lovely, see you later. now the weather with simon. the weather i guess is helping things at the notting hill carnival. temperatures across the south—east potentially up to 29 celsius. it could be the hottest late august bank holiday on record. you can hottest late august bank holiday on record. you can see hottest late august bank holiday on record. you can see the extent of the sunshine from south to east. further north and west more clout and with that, outbreaks of rain across scotland and into northern

ireland. it is moving further south. getting brighter in the far north—east. hazy sunshine in wales and north west england later. in these north—west areas, temperatures 17-20d. in the these north—west areas, temperatures 17—20d. in the south east, widely in the middle and high 20s. in the evening, fine and dry. more rain spreading south and into northern england. it will break up further as it pushes south and east on tuesday. just a zone of cloud. a bit cool and fresh in the south. 23—26. treasure elsewhere across the uk. 20 celsius but sunny spells and a few showers. —— temperatures —— pressure elsewhere across the uk. —— fresh elsewhere. hello. this is bbc news. the headlines: 3,000 soldiers are being sent to houston to help residents affected by severe flooding in the wake of tropical storm harvey.

more than 130 people have been treated in hospital and hundreds more affected by a mysterious gas cloud that drifted in off the sea in east sussex. a lorry driver has been held in custody charged with the crash on the m1. -- custody charged with the crash on the m1. —— charged with causing death by dangerous driving. the third round of brexit talks take place in brussels this afternoon, with british negotiators urging the eu to show flexibility and imagination. a controversial guru has been sentenced in india for raping two of his followers. now on bbc news, click is all aboard india's technicolour dream train. we are hitting the road, rail and the water. there will be and singing. kind 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 closer, 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 has 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 115,000 kilometres of optic fibre and google is piping internet access down those cables to feed wi—fi access to 114 other train stations as well. i caught up with he man overseeing the project while he was waiting for his train. if you had to take one place in the country where you want tremendous fibre and you had to have reliable power, relatively speaking power is a challenge across the country and you had to have an entire country walking there, that one place, there is only one place that is the railway stations. can you guarantee that all services on google's wi—fi will be treated equally? absolutely, i think the whole 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 access for 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 affects that's 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 here

to jaipur to investigate, it has proper broadband and it's free. people are filling their boots. apart from some controversy at another station where commuters were using 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, the news, the office work. ifind it quick, yeah. for this studentjournalist it means she can keep tabs on breaking stories. in the morning the world changes like... there are so many things that have changed so i have to come and check. indian stations are full of thriving

businesses feeding off, or simply feeding, the thousands streaming through them every day. free wi—fi has actually been a boon to local businesses here. ashok runs a tea store on the station platform. 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 doesn't catch. when that's not working i use the wi—fi. especially when a customer is paying through digital payments, i needed to confirm that i have received the payment. digital payments are worth about 40 to 50% of my takings. this is music to the ears of people managing india's railways, a nationalised industry that runs at a loss. they are thinking 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 becomes taken for granted then i think people will transact more and more of their business. jaipur is a kind of domestic, tourist hub and an international tourist hub of high repute. people are coming out here from all parts of the world so now when you have a huge concourse it becomes an area where you can have shops, entertainment spots... 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 as least as far—reaching. the roads here are, well, utter

chaos. all the more astonishing when you consider that so few people own a car here. there arejust you consider that so few people own a car here. there are just 32 you consider that so few people own a car here. there arejust 32 motor vehicles per 1000 people in the country. in the united states there are 797. but that number is changing andi are 797. but that number is changing and i will tell you a secret, it is not going down. look at these roads. that is a pretty scary thought. 0ne solution could be to make better use of the cars already on the road. enter india's biggest taxi hailing app, the google of india, if you will. 0r app, the google of india, if you will. or as they say,... they had taken full advantage of their head start. it has historically been

number one in india, but uber said thatis number one in india, but uber said that is changing. it looks like the battle for cash is changing. this is india's silicon valley, bangalore. this is employer number one. the country is not designed to have the car industry. not even more than 10%. what are the needs of your customers and drivers in india? we made an exclusive pact that —— platform not only about taxis but some of the taxis in india, the buses we have, minibuses that we have, bikes in some cities, electric ca i’s have, bikes in some cities, electric cars and so on. it's a platform for mobility where you have different transport options and different price points for different cases. that brings in a lot of options for users. ola said it is better because

it is local and it knows what works in india, meaning offering 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 them and how you will you stay ahead ? different from them and how you will you stay ahead? i think there is a difference in the way we operate. we believe in what we want. not in what we have. in terms of plugging in things which have worked in markets. you need to build it ground up. it is about the connection you make and not just the transaction relationship you have with the drivers. part of that connection is offering centres like this. here drivers can talk face—to—face with the 0la, for example when theyjoin the 0la, for example when theyjoin the service for training or if they have problems. an issue with wages, for example. but 0la does not actually employ any of this. the controversial system is used by

other transport and delivery companies around the world to keep costs down. despite this, 0la really, really wants drivers to drive a lot. so much so there are carrots if you stay on the road. sticks if you do not. we are producing —— we are promoting

new sustainability. this is something we are focusing on in a big way. we want all makers to be electric by 2025—30. it is one of the most successful start—ups to come out of the indian education system in recent years. called indian institute of technology, iit, these top level universities are dotted across the country and are a driving force behind many of the country's tech successes. getting into iit is incredibly competitive asa into iit is incredibly competitive as a business. 0nly into iit is incredibly competitive as a business. only a tiny fraction of applicants get in in any one year. if you do you get to work in incredible campuses like this. my my first as the olympic sized swimming pool. it is not me taking a dip. this is named after the avatar

vishnu taking the form of a fish. it isa vishnu taking the form of a fish. it is a multipurpose robot that can operate automatically without human controlling to locate sounds and recognise rab and manipulate objects. the team tell me it might be used to find flight recorders from crashed aircraft. they are also pitching in to the military to fire torpedoes. the project is in its fifth year and the team leader said the work is hard but it can be massively wide ranging. what we especially like about it is that we have got a way to test it out... like a racing car or a satellite. brilliant. this is one of 100 projects supported by iit bombay‘s society for innovation and

entrepreneurship since 200a. it is an umbrella for start—ups and as with incubators everywhere you will find all kinds of ideas bubbling away behind the 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. do—de—do... do-de-do... you do-de-do. .. you got some kind of score here. the worst karaoke india has ever heard. but this singing and training application is so much more than normal karaoke style. most apps doa than normal karaoke style. most apps do a very cursory evaluation of your singing. some don't even evaluate yoursinging. you singing. some don't even evaluate your singing. you just open your mouth and get a good rating. what we

do isa mouth and get a good rating. what we do is a multidimensional evaluation on different aspects of using, rhythm, vibrato, falsetto, dynamics, timing... you asked for a hard exercise! eee...... ifmy eee...... if my singing went right through you i have got something u psta i rs through you i have got something upstairs that will really cut to the bone. this search team are working ona bone. this search team are working on a system to help surgeons plan surgery. on a system to help surgeons plan surgery. they have created software learning to create a 3—d model of bones from just two two—dimensional x—rays. bones from just two two—dimensional x-rays. i can imagine after a lot of experience, this bone, looking at an x—ray, i can imagine it in 3—d, can we do the same with computers? a surgeon can we do the same with computers? a surgeon can do it because he has

learned correlation between the imaging and doing this subject. we use imaging and doing this subject. we use the same logic. to develop the software. we have a machine that has learned the 3—d shape of bones across the population. we have created a lot of 3—d models from the scan. and we use this and we create it to understand data in a particular way to predict from the image. these 3-d models also allow for tools and guides to be designed to the patient‘s specific dimensions. for example, ifa surgeon dimensions. for example, ifa surgeon prepared to cut and realign legs. we have this specific implementation using bone surface and it is like a negative of the service —— service. if you make that pa rt service —— service. if you make that part and print in 3—d and put it on the real bone it will exactly fit. what we do is we use that concept to

cut, to make surgeons cut more accurately. this part will be an exact fit on the bone but also have a slit which will align with the cutting plate. that can be used in surgery cutting plate. that can be used in surgery to guide cutting. two x-rays are cheaper than a full mri scan and once again it means the patient can be assessed when they cannot get to a fully kitted out hospital. it is no surprise many projects here concentrate on low—cost rugged solutions to developing world problems. you may have come across these displays before which allow you to connect on bluetooth to your android tablet. whichever menu item is highlighted on the screen, the text is mirrored on the braille recount here and you can control the navigation using the up and down buttons here. this is a prototype display which works in a slightly different way. the braille displays

currently existing on the market are based on electric technology. and because of that very thing the cost of these devices are around $3000 each. we have developed a completely new technology based on magnets where we can reduce the cost ten times. we can sell it to the user at around 300— $1100. this machine needs to work for at least 10 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 and rugged device. that is the challenge. this is the urdu primary school in karnata ka. challenge. this is the urdu primary school in karnataka. there is 155 kids here from grade 1—7 and a whole bunch of dedicated teachers. this is how they start their day... they

sing... 0ver how they start their day... they sing... over in the next classroom things are a little more serious. at the back there is an android device plugged in and running videos on english, maths and science. videos are made and they are dubbed in different languages depending on where they are sent to. today we are learning about fractions. it is a great teaching tool, as long as there is electricity. but there are plenty of times when there is not. early on it would be difficult to teach because of power cuts. we

would get electricity in the morning but as the day passed by, in the afternoon we would have power cuts more than two hours. that is why the project and tablet are hooked up to a box itself attached to a solar panel on the roof. together they can provide up to five hours of electricity per day, meaning classes do not have to be interrupted or cancelled if the power cuts out. translation: then we started using solar power. it isn't easy and natural source of generating electricity. we introduced the study of generating power and solar energy to students. —— each is a very easy and natural source. we explain to stu d e nts and natural source. we explain to students this process will help us in future to generate electricity. this whole system has been provided by the cell co—foundation, an indian charity helping to alleviate poverty by improving access to energy. so actually students can get a better education with the team and there is

no problem for electricity. any time the teachers can take their students to the classroom and they can teach with this medium. this company and other ngos they work with meet half the cost of installing the system and the other half comes from local schools, or local government. how important is the projector...? translation: we had very few stu d e nts translation: we had very few students before but since we had started using solar power, the number has increased in a good way. we have students coming to us from different villages to learn. not only students. we have other schools coming down to the institute for smart classes. the smart class is a good way to teach kids these days. they seem to enjoy and learn more than usual. after we introduced smart class, the school stands proudly in the educational sector. we plan to grow larger has the years pass by. the same system is already

in hundreds of rural schools. they are aiming to add hundreds more this year. it is not just it is notjust key for schools. across rural india businesses can be massively helped by having a reliable power supply. this is a sea mstress reliable power supply. this is a seamstress living a short drive from kabul. she became the family's main breadwinner after her father was taken ill. breadwinner after her father was ta ken ill. the breadwinner after her father was taken ill. the more she can repair, the more she can get paid. with the old and operated sewing machine she could fix a couple of items per day but thanks to the solar panels, her machine can whizz through five or six items per day. she also has a fan, tv and light, so she can work earlier and later. 0ne quarter of india's rural population is living below the

official poverty line, 260 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. always such a privilege to come to a place like this and see how the simplest of technology can make a world of difference. that is it from india for the moment. you can see plenty of photos and more backstage gossip on twitter. thanks for watching. see you soon. good morning. many of us enjoying

fine sunny weather across the uk today. the best sunshine is down to the east and south—east of england. that is where we could get up to 29, maybe 30 celsius. it would make it the hottest late august bank holiday we have recorded. but not sunny everywhere. as you can see we have got more cloud across scotland, northern ireland, some rent dregs of rain, gradually moving south. —— outbreaks of rain. in north—west england and wales, some hazy sunshine this afternoon. largely sunni in southern england. getting up sunni in southern england. getting up into the mid and high 20s. a bit more cloud into what's wales and the north—west of england. —— north wales. some rain moving into the la kes, wales. some rain moving into the lakes, as well. in south—west scotland, northern ireland, the rain continues here. northern scotland,

after the rain is clearing to the south, brighter and sunnier spells. in the north and west, temperatures 17-18. not in the north and west, temperatures 17—18. not enjoying the heat in the south—east. potentially 29 celsius. in the evening, a fine end to the day for many but that rain in scotla nd day for many but that rain in scotland and northern ireland gradually moving further south and east and breaking up as it does so. quite a warm night in england and wales. temperatures 15—17. but cooler and pressure in scotland and northern ireland. 0n cooler and pressure in scotland and northern ireland. on tuesday, this cloud and rain will move its way further south, breaking up, cloud and rain will move its way furthersouth, breaking up, really, a zone of clout in the south—east, still sunshine across the far south east and temperatures down by some degrees, but still warm at up to 26 degrees. elsewhere is noticeably more fresh. highs of 15—19dc. 0n wednesday, two areas of low pressure are moving in, converting together,

bringing outbreaks of rain on wednesday in england and wales. it could be heavy across the south of england. largely dry with sunny spells for scotland, northern ireland and some showers. temperatures in the south—east down by several degrees competitive day —— today. pressure by wednesday and on thursday and friday, around 16-20dc. a mix on thursday and friday, around 16—20dc. a mix of sunny spells and showers. just to summarise, it is a warm and if not hot start to the week, cooler by wednesday and by the weekend, high—pressure returns and it should be largely fine and dry, again with some sunny spells. this is bbc news. i'm joanna gosling. the headlines at 12: with water levels rising fast in houston in the trail of tropical storm harvey — tens of thousands more people are told to leave their homes. this lady, she will not come out. she is handicapped. she is over here
