and change the world. strawberries ina and change the world. strawberries in a massive box. and fancy working in an enormous train station? i don't know if you have noticed, but there seems to have been the lot of election talk of late. this week, click is taking a trip to paris, where this weekend, the french take to the polls in the first round of their presidential election. and, curiously, from a technology point of view, the way we vote seems if anything to be going backwards. in the last election, france did allow online voting for those living overseas. but not this time. for both the presidential elections and the legislative elections injune it is back to pen and paper. and that is back to pen and paper. and that is due to the fear of cyber attacks, which the french nationals cyber security agency says are an extremely high risk. queues of people, paper voting... surely extremely high risk. queues of people, papervoting... surely there has to be a better way. well, we asked abc news beat‘s political editor, jonathan blake, to have a look. ancient institutions and modern technology. the two do not a lwa ys modern technology. the two do not always go together. as elections are held worldwide throughout 2017 that could radically reshape the political landscape, most people will cast their vote in the same way it has been done for decades, using a pencil and paper to put across in a pencil and paper to put across in a box. in the uk, election turnout has fallen steadily. those campaigning for online voting say the system is stuck in the past, and it is time to digitise our democracy. it would make politicians pay attention more to the groups that would be an franchise by this method of voting. so those groups would be young people, because they are the ones who engage most online. and groups like people with disabilities or with vision impairments, of whom there are two million in this country, voters abroad, and the armed forces, if they have this accessibility to boating, politicians will have to listen to them. one company is working on a way to make voting more convenient, and they say, more secure, with an app that lets you register and vote by selfie. uses facial biometrics and combine that with some sort of government document, whether it is a passport 01’ document, whether it is a passport or driver ‘s licence, to create a digital identity which the voter is in control of. so this is a demonstration version of the app which smartmatic have made. we will start registering, first of all. it is asking me to take a selfie. panik stages to add photo id. we will go with drivers license because i have that handy. 0nce with drivers license because i have that handy. once the idea is matched to yourface, that handy. once the idea is matched to your face, the apple confirms you are registered to vote. and we are voting for rush field borough council, which is not a real place. it is asking me to take a photo, so i hold up a camera and phone will ta ke i hold up a camera and phone will take a selfie automatically. so here there is a list of candidates, the same you would see on the ballot paper. i don't need to tell you who are voting for, so i won't, i will pick one at random. and that's it. it says you have cast your vote successfully and it has given me a unique receipt number which i can either copy or centre myself by e—mail. you are asking people to ta ke e—mail. you are asking people to take a photo of their face, capture an image of the photo identification. how secure is that information. where does it go? the digital identity you create is unique to you and it stays on your device, on your personal mobile phone or tablet. whatever you use to ta ke phone or tablet. whatever you use to take it. it doesn't get stored anywhere. you are in control of it at all times and you are in control of what pieces of information you use to create that idea, and who you share it with. when it comes to security, we apply a non—standard, additional layers of security, in terms of really strongly encrypting the vote on your device, to add that additional layer of protection. but concerns about cyber security mean countries once embracing the use of technology in democracy are having second thoughts. in the netherlands, where the voting system has been computerised since 2008, this year they are counting votes by hand. but they are counting votes by hand. but the country that has earned a reputation as the electronic voting capital of the world is sticking to its guns. estonia is almost the sensitive about its digital identity. here in estonia, everyone from the age of 15 carries a government issued photo id card. using this an accompanying pin numbers you can access using this an accompanying pin numbers you can access your using this an accompanying pin numbers you can access your bank, phone company, energy firm, and a lot of official information. you can see this man's name, address, date of birth, where he went to school, health records, everything down to what car he drives. in estonia, voting is just another thing you can do online. download software, user id card and pin to make a selection, and vote from the comfort of your home or wherever is convenient. around one in three voters now cast online, but officials admit it has not boosted turnout. the internet voter is a transformed paper voter. having a novelty, a convenient method of voting, is not enough to bring people from the no voting zone back to voting, or to voting. 0f course, you need other incentives. you need policy, you need reason to vote. i think it is interesting, but it needs proper security, and right i'iow it needs proper security, and right now the measures are not good enough, in my opinion. using the smart idea we have, it is easy and quick access to everywhere.” smart idea we have, it is easy and quick access to everywhere. i have used it, and i think it is very useful and it is very convenient. so i don't have to go somewhere to queue. other countries seem relu cta nt to queue. other countries seem reluctant to follow estonia's lead. a british minister responsible for elections told me the government is looking only at taking very small steps. they have identification cards, and they keep the systems. it isa cards, and they keep the systems. it is a very different space to what we have in the uk where they don't have a privacy agenda about protecting individual citizens' rights, and protecting their own data. people are happy to do their banking online, shopping online. why not use technology to enable people to vote more easily? going forwards, we have got to make sure that while we embrace technology and we embrace things like online registration, online voting is a situation where if we believe the current paper and pen method is the best way forward, than actually it means that each individual‘s vote is counted equally, one voter, one vote. as technology advances, calls to digitise democracy will continue, but so will concerns about cyber security. so the pencil and paper may well always have its place. that was jonathan blake, may well always have its place. that wasjonathan blake, and world technology may not be applied to voting at these french elections, it has certainly been causing a stir in other ways. keen to draw attention to his campaign, a far left candidate took to the stage this week, addressing a crowd of 6000 at a rally in dijon. but at the same time appeared at six other rallies across the world. they call it a hologram, we call it smoke and mirrors. it is not the first time politicians have used this tech to further their agenda. politicians have used this tech to furthertheiragenda. india's politicians have used this tech to further their agenda. india's pm narendra modi used it during his campaign, and the turkish president, erdogan, used his avatar to appear ata erdogan, used his avatar to appear at a meeting he couldn't make in person. a politicaljournalist, sought melenchon's first meeting. person. a politicaljournalist, sought melenchon's first meetingm was a meeting in france, he was out lyon, with marine le pen, and there was at the same time a big meeting with macron, in lyon, as well. so he knew that he was not the top politician. so it was a matterfor him to be... to stand out. yes. now, we have seen the peppers ghost allusion before on click, and even allowing me to get down with psy in korea. but addressing melenchon allowed him to address six venues simultaneously. the trick was to arrange film lighting, which is pretty much identical to this, on a trust, a picture frame trust, very similar, and angling and lighting the stages. all around the destinations you are broadcasting to. the camera in front of the stage filmed a wide shot, and the signal was broadcast over satellite 25 french cities, and reunion island, off the coast of madagascar. do you feel that this is the way that elections will be fought in the future, with holograms and technology and showmanship? no, i don't think so. i think it is really a true for melenchon. the media were already there to see and to speak about it. i don't think that it is the way of making politics for the future days. what will this tech really help connect voters to politicians, or is this transparent projection just politicians, or is this transparent projectionjust a politicians, or is this transparent projection just a gimmicky barrier that gets in the way? egalite, oui! welcome one at all to the church of facebook, this is f8, the company's development conference which this year is being held in sanjose. i am here to find out what mark zuckerberg things we will want in the years and decades to come. i will start with the stuff that is happening right away for. facebook, you will know that have notice, is locked in a battle over augmented reality tools like this. you can have a second coffee mug so it looks like you are not having breakfast alone. facebook also launched spaces, a place to interact with avatars of your friends in virtual reality when you can't look up in reality when you can't look up in real life. the company is also releasing these curious little cameras for capturing real—life scenes, in full, cameras for capturing real—life scenes, infull, high—quality cameras for capturing real—life scenes, in full, high—quality 360. the innovation here is that ability for the camera to record footage which has depth. it allows what is known as six degrees of freedom. i can lead in —— lenient and kia around, even though the camera which took the footage i am seeing hasn't actually moved anywhere. in the past, you were frozen in the middle ofa past, you were frozen in the middle of a world, as if you were seeing a painting on the ceiling. we wanted you to actually be able to lenient and actually see the depth. at here isa and actually see the depth. at here is a need little trek. the depth perception also means you can add a kind of green screen effect without needing a green screen. once you have that information, it is really built on the fact that you have ca ptu red built on the fact that you have captured the depth. you not only know the colour of that flower, you know the colour of that flower, you know how far it is a way, and you know how far it is a way, and you know how far the ground behind it is a way, and you canjust know how far the ground behind it is a way, and you can just subtract the ground away and replace it with grass, instead of rocks 0rbach. ground away and replace it with grass, instead of rocks orbach. f8 is also about thinking what made it coming much further down the line. this little helicopter is another one of facebook‘s attempts to bring connectivity too difficult to reach places. it is tethered to the ground, but once in the air it can beam internet to an area below, perfect for helping people in disaster zones. they have made it in conjunction with the san francisco —based start—up. conjunction with the san francisco -based start-up. the idea is to basically build instant infrastructure. so it is an aircraft ona infrastructure. so it is an aircraft on a tether, where fibre and power run—up essentially the strongest your mac longest extension cord you have ever seen, your mac longest extension cord you have ever seen, so your mac longest extension cord you have ever seen, so in an earthquake ora have ever seen, so in an earthquake or a cyclone, you can set up in the sky and instantly provide internet to all the people who need relief, and can't be reached because of disaster. and then, just when we thought the new ideas were over, things got weird. what if you could type directly from your brain? even something as simple as a yes/ no brain click would fundamentally change our capability. it is many yea rs off. change our capability. it is many years off. they may never be able to do it. but this is the plan. hardware and software that would allow you to post to facebook without moving a muscle. so that's it for another year, and as they pack up, we are all left pondering the question, do i really want to plug facebook into my brain? now, back to paris. and how would you feel about renting your car to a com plete you feel about renting your car to a complete stranger? well, believe it or not, here, there is an app that lets you do just that. drivey has been operating for six years. over 40,000 car owners have chosen to list their cars on the platform, mainly in france, germany, and spain, racking up 1—and—a—half million days of rentals. the alp gives me a list of vehicles available in the designated area. and then i can slow through pictures and details of each car. —— app. it is basically a b&b for your car. —— airbnb. here in the start—up, it has all the signs of a start—up. and how they convince people to learn their ca rs they convince people to learn their cars to others? because i am british, maybe, buti cars to others? because i am british, maybe, but i think it is a crazy idea to hire my car to other people. giving norn would partake in this because of the risk and damage? we knew from the start that it would sound like a crazy 80 two rent your car to most people. but the question is if some people would agree it was a good idea and efficient, and these are the people we target. give it is are the people we target. give it is a reason why sharing services do very well. i think that special because it has the fact that businesses go well in the law is enforced, with still a mediterranean culture. british and americans are more scared about lending their ca rs. more scared about lending their cars. i heard that you teach kids about stranger danger in britain. and that is something we don't know in france. and maybe less trusted people you don't know and less willingness to share time or things with other people. you have been to london, then, clearly. can you find a lost car? we can geo- locate cars and see where the car is going and how it is behaving. you can use the accelerometer to sit there are in fa ct. accelerometer to sit there are in fact. —— impacts. the development is an autonomous cars are playing to our favour, because the amount of darker and control over the way that it is driven is going to increase until it is autonomous, and then whoever is in the car is no longer a problem, except for sandwich crumbs or something like that. in their early stages, start—ups like drivy famously used desks anywhere they could find them. and very soon, a lot of those desks could be here. in the biggest start—up incubator i have ever seen. goodness me! and thatis have ever seen. goodness me! and that is because when it opens in june, this 90—year—old paris train station will become the world's biggest start—up incubator. the director spoke to me earlier. what i like are these future pods apa. what are those? these are our meeting rooms. “— are those? these are our meeting rooms. —— “— are those? these are our meeting rooms. —— —— pods up here. are those? these are our meeting rooms. -- -- pods up here. massive walls, pens they are, you can put things up on the walls?|j walls, pens they are, you can put things up on the walls? i hope so. if you are a start—up, you need to write on the glass. station f is full of big numbers. privately funded, it cost 250 million euros. it has 34,000 square metres of floor space. it is as long as the eiffel tower is tall. it will seat 3000 entrepreneurs, and that is just in the middle section. we have not even got to that bit yet. so this is the start—up zone. got to that bit yet. so this is the start-up zone. oh my goodness, that is insane. and filling it with building dust like this makes it look awesome. and below us, we actually have showers and lockers if an entrepreneur was to stay all night, he can. what you mean if somebody was to stay all night? that is part of an entrepreneur! it may seem like overkill, it does to me, but roxanne is confident that france can not only compete for start—up interest with the likes of the us and the uk, but in these uncertain times, it actually has an advantage. we've actually seen the impact of brexit, we have seen the impact of donald trump in the us, and silicon valley prices of its currency —— have been skyrocketing. a lot of countries that would have looked at uk are now looking at france and other places in the eu. france is currently second, behind the uk, in terms of both money raised in the darker, ai, and other deep tech in the last two years. —— data. and also in the size of its workforce. so it might not need a massive leap. everybody gets a locker? everybody gets a locker. i like this under lighting. do you think in france, there are more regulations, more red tape, more official stuff that you how to cut through? i do think that administratively, it is a place that has potentially more complexity than elsewhere. it depends on what ecosystem you a re elsewhere. it depends on what ecosystem you are comparing two will stop them may promote seen here in france is that things change. when a new administration comes in every three years, we are changing things that we have put into place. and start—ups cannot keep up. every yea rs start—ups cannot keep up. every years they have a completely different tax credit or scheme, so there needs and that is stable and that they can count on. not that red tape is was a problem here. one start—up ina tape is was a problem here. one start—up in a northern suburb has really been given permission to place three of its pods around the city. so, what on earth is agricool that makes the shipping container so desirable? it is a strawberry farm! you probably know that fruit sold in city supermarkets has usually been ona city supermarkets has usually been on a long journey over several days to get there. and that means it has to get there. and that means it has to be picked before it is right and is not as sweet or nutritious as it would be if it was left on the plant. this is a way of keeping fruit on the plant in cities until the very last minute. there you go, for walls of strawberries bedding under led lights. these are the sources of water in a closed loop system. here are your nutrients, and over here, a box of bumblebees. did you know you could order bumblebees by the box? i didn't. that is where they live, and that is where the pollination occurs. agricool is currently experimenting with different colours of light and different colours of light and different mixes of nutrients in order to get the very best strawberries. inside, we are creating a real paradise. based on their, the c02 level, the best light. it is 125,000 times more productive. using 90% less water. no pesticides, and only renewable energy. the two founders, sons of farmers, have noticed how tomatoes and strawberries that have been transported over long distances are tougher in order to survive the journey. they try to find the best pieces, they can last longer, that have lighter skins than the fruit usually does. more skin and less fruit inside. it affects the case. just to be clear, the shipping containers won't move. they will be permanent fixtures in cities. and with a minutely controlled climate, a new batch of strawberries can be grown in another room weeks —— every 11 weeks. giving people in the city the case to the country all year round. if you dig about the amount of agricultural land that has been swallowed up across the planet every day, this could be the future of buying. —— if you think about. that is it from paris for the moment. there seems to be a lot going on here. we had to come back soon. but check us out on twitter. —— have to. hello there. we may well be heading towards the end of april now, the weather is feeling a little bit wintry, particularly next week we have got some chilly weather on the cards. during friday there was some glimpses of sunshine, this was the view taken in south yorkshire by one of our weather watchers and during the weekend there will be a bit of sunshine and things mostly dry but temperatures still on the cool side, not as cold and frosty as earlier in the week. during saturday we've got this weather front working its way slowly south across parts of england and wales introducing a bit of cloud, perhaps the odd spot of light rain here and northern ireland seeing some cloud and some drizzle. through the day some showers pushing into the north of scotland but elsewhere quite a good deal of dry weather. this is at 4pm on saturday afternoon. fairly cloudy for a time in central and southern parts of england, maybe the odd light shower and temperatures up to 15 or so. sunshine in east anglia, the midlands, parts of north wales, mostly cloudy for northern ireland but some brighter spells potentially and in scotland and northern england, some sunshine, but to the north of scotland we'll continue to see showers and a bit of snowfall on top of the mountains. then moving through saturday evening and overnight we'll continue to see the showers in the far north and north—east of scotland. the winds tend to come down the east coast too so quite chilly around the east coast. clearer skies so first thing sunday temperatures lower than this in the countryside, but even in towns and cities down to around five or six, so a cold start to sunday morning. if you're planning on running or watching the marathon in london you might want to wrap up warm first thing but by the afternoon, sunshine breaking through and that should lift the temperatures into the mid—teens. across much of the country sunday not looking like a bad day. probably a fair amount of sunshine, some rain for the far north of scotland, most other places dry and temperatures typically between 11 and 12 in the north, 15 or 16 further south. high pressure not far away as we look through sunday night and the new working week and then we see low pressure moving in from the north, and this is when we introduce that very cold air, look at the blue colours and the northerly arrows moving from monday into tuesday, we could even see some sleet and snow showers around too. monday into tuesday, one or two wintry showers particularly in the north and east. further south it's colder and there will still be some sunshine in between those showers. to summarise the weather into next week, staying pretty cold, a bit of sunshine around, wintry showers and most places largely dry. bye— bye. hello, my name is tom donkin, with bbc news. a very warm welcome to our viewers in north america and around the globe. here are our top stories: french officials say the gunman who shot dead a policeman in paris had been jailed previously for trying to murder officers. us ground troops have killed a leading member of the islamic state group in a commando raid near mayadin, in syria. anti—government protests continue in venezuela. 11 people are killed in the latest violence and looting. the duke and duchess of cambridge. go. he had 13 weeks as number one before harry came along and spoiled his easter. and from takeaways to game of thrones, wills and kate take to the airwaves for some revealing regal radio.
