this week, in—your—face pollution! retro electric cars and spaceships roasting coffee. this is the site lots of cities gci’oss this is the site lots of cities across the world wake up to every morning. pollution well over the safe limits. we now know this is killing more people than smoking.

this week the ultra low emission zone launches in london. it hopes to keep the worst polluters off the streets. but whether a £12.50 surcharge. enough people using their vehicles is, some might say, questionable. it is a beautiful day in london today and right now pollution levels aren't too high. but, hour the story changes. this goes beyond the busy roads, too. london's deepest tube stations, study suggests, can be 30 times more polluted. at london marylebone, a new airfiltering polluted. at london marylebone, a new air filtering system is trying to tackle the problem. well, i wouldn't usually be standing this close to a fan blowing air in my face, but apparently this is giving me the cleanest air in the station. behind there ‘s advertising board is

a contraption containing a nano carbon filter, capable of removing over 90% of harmful gases from the environment. the devices are deliberately positioned alongside the shops and waiting areas where most passengers spend their time. this map shows how the quality of the air is improved significantly where the filters are. the polluted air is being sucked in through the top of the unit and sent to a chamber in which there is a high—voltage electrical field where the ultrafine particles are being captured. the second stage is then a gas filter where we take out the nitrogen dioxide, we take out the eventual ozone that is produced in the first chamber, and then the last chamber is to direct the airflow out to get the clean air in the right place. but it's notjust london.

last year a0 cities across the uk either reached or exceeded the safe limit for either reached or exceeded the safe limitforair either reached or exceeded the safe limit for air quality. and some have their own plans to better the air. in southhampton, this bus is claiming to clean the air as it drives. the filter on the roof removes the ultrafine particles from the air that diesel engines on vehicles like these are spewing out. basically there are two large filter papers, filter slabs in the unit. there are three fans that suck air in. the bus doesn't go fast enough to get the air in so we have three fa ns to get the air in so we have three fans driven by electricity. they suck air in. it is filtered on the roof of the bus and it comes out much cleaner when it comes out the other end. and the hope is it could doa other end. and the hope is it could do a lot more than clean up its own act. if the city's 5000 buses have these filters they could, in theory, clea n these filters they could, in theory,

clean the entire city's air twice over. after what height of ten metres, at least. i suspect that cities that might be interested in looking at this sort of technology and if it is not a bus it could be a refuge vehicle, delivery laurie, on all sorts of things. now we don't need to just keep things running with low emissions. keeping things running at all can be a challenge stop imagine the chaos if these traffic lights went down. now imagine if the whole system went down due to a cyber—attack. but it's not just about transport networks. it's also large factories or power stations which have already fallen victim to these types of attacks. and dan simmons has been shown to new research which suggests our infrastructure might be a lot more vulnerable than we previously thought. the ukrainian example is presumably

done by a nationstate actor and there they were able to successfully turn off the lights in a neighbourhood. and that, to my mind, shows just how severe the consequences are. this man has been helping secure the energy and utility sectors for almost ten yea rs. utility sectors for almost ten years. you may want to disrupt oil and gas markets. the saudi example was the more recent of the two. that was the more recent of the two. that was one where presumably a nationstate actor was specifically targeting safety systems and oil and gas refineries. the assumption was directly trying to cause physical harm and that one was really scary because they were directly going after the safety systems. so where does it all begin for the countries 01’ does it all begin for the countries or criminals behind such attacks? today he has offered to show me a two called showdown. joe dunne specifically tells me what devices are open facing to the internet. what that tells me is that there is

pa rt what that tells me is that there is part of my attack service, that is out there and it probably shouldn't be out there it helps me then prioritise where i am expose and reduce risk. we are searching for these. individual bits of kit that controlled the big industrial systems. they are called programmable logic controllers and if you are running a water plant, power station, factory, for example, you don't want to just anyone fiddling with them. we know there is 110w fiddling with them. we know there is now 6000 of these connected to the internet. this is real time stafylid is real internet. this is real time stafylidis real time they should never be connected to the open internet like that. there are over 5000. this is a list of the countries where they are located. and so the power of the tool is the ability to click down. there is nearly 1000 of these in germany. so let's pull that up. what this will start to do is give us more information on the specific devices,

companies, where they are. just to give you a sense, you have a wide range of leading german companies, smaller manufacturing firms, what we're finding is that industrial control systems are vulnerable everywhere. it is a risk for everyone. it is part of your cyber exposure. many of the control systems and infrastructure are old andi systems and infrastructure are old and i get a software update that often. it is one reason to keep them off—line. but increasingly we are connecting more devices to the workplace so the opportunities for an attack go up. this week an independent report conducted by a specialist research agency suggests afar specialist research agency suggests a far worse picture than previously thought. nine out of ten of the 700 security professionals working in critical infrastructure that took pa rt critical infrastructure that took part in the survey commissioned by tenable said their workplace had suffered damage as a result of at least one successful cyber—attack in the last two years. but does it mean systems also went down? if you look

at healthcare, oil and gas, utilities, transportation. roughly half of them in the last two years of experience some sort of attack or a breach around the industrial control systems that has led to a shutdown. now, i think it's control systems that has led to a shutdown. now, ithink it's fair control systems that has led to a shutdown. now, i think it's fair to say that you have to take this report with a pinch of reality, because the experts that responded did so possibly because they had something to say. they might expect the figures to be a little bit higher than, perhaps, what is truly the case. but even allowing for an adjustment for that, this report paints a very different picture to the everything is ok scenario that the everything is ok scenario that the public might be persuaded to believe. underreporting of cyber attacks against critical infrastructure is commonplace and it's not just infrastructure is commonplace and it's notjust to protect reputations. it's in order to keep the confidence of us, the public, in the confidence of us, the public, in the services provided to us all around us every day. the anonymity

provided to the workers who responded to this are not the ceos or the bosses, may also have loosened some tongs. back at the board and we've narrowed our search to one particular programmable programmer that is known to have security problems. what i have been able to do is find this device with able to do is find this device with a known vulnerability found by tenable. surely nobody would leave these connected to the internet. you even have a gps. you can find it on the map. what i am able to do now and again remotely is click into the device and i can remotely change the password. it's notjust this one company. shower down delivers up dozens company. shower down delivers up d oze ns of company. shower down delivers up dozens of potential targets for us, including a major telecoms provider in the uk, germany, and in this scan, romania —— showdown. showdown and tenable help companies find where their vulnerabilities are. but

our organisation is doing enough to protect us and could this happen ain? protect us and could this happen again? absent electricity core function goes down. you don't want to lose medical care. the consequences can indeed be quite severe. as to the motivations of the attackers, i don't know, but certainly nothing good. it's a way to almost disable a modern functional society. what do you believe is the probability of an attack on that scale in the united kingdom? on that scale, quite low. i think it's important not to fear mongering like that, right. the risk is real, the vulnerabilities are real comedy cyber exposure is growing. there is that gap that you andi growing. there is that gap that you and i talked about earlier, but that doesn't mean the lights are going out in london next week. and i think we should be really sober about the risk. you don't need to exaggerated in order to address it. and if they do go out, if this programme goes out after such an attack... and i

was wrong? i trust you'll editor thoroughly. hello and welcome to the week intact. it was the week that google finally shut down its failed social network goolge+. tessel was fined for violating laws hazardous waste storage at its california factory. an toyota announced it will offer free access to as hybrid technology patterns until 2030 to encourage a transition to full electric cars. the clearing of the backlog of marijuana possession convictions will be helped along by artificial intelligence. an algorithm will determine if cases are eligible for dismissal or resentencing. it will help clear 5a,000 convictions. recreational use of marijuana was legalised in the state in 2016. nasa is wanting a satellite down by india is wanting a satellite down by india is at risk of endangering international space station, calling the destruction a terrible, terrible thing, nasa's she said a00 pieces of

orbital debris created, 2a pose a risk to the arsenals on the station. a woman carrying two chinese passports, multiple phones, and a thumb drive with malware was arrested at president trump's mar—a—lago resort in florida. she told them she was at the club to use the swimming pool. before she said she was therefore a nations event. 32—year—old woman was removed and arrested. and, finally, do you fancy working alongside this? boston dynamics have shown how was gigantic handle robot can be put to use in a factory. here it is accurately moving boxes between pallets. they weigh about five kilos each but the robot can lift up to 15 kilos. terrifying and useful at the same time. 0bviously time. obviously an easy way of helping reduce pollution in the city is to encourage people to cycle more.

doctor spike schemes that became popular in asia have started popping up popular in asia have started popping up in cities across the uk in the last couple of years. unlike the so—called boris bikes, they don't require any infrastructure. cycles can be left anywhere, anytime, and be picked up by another user. while this might be ok in some countries, here people didn't find it quite so acceptable. so now a new crop of dr alit schemes are hoping to keep eve ryo ne alit schemes are hoping to keep everyone happy. i'm not much of a cyclist myself, so i needed a spot of help. kitty knowles has taken one of help. kitty knowles has taken one of the brand—new barrel bikes for a spin before they hit the streets in the seaside town of bournemouth and here in east london. well, kitty, you have been getting exercise today. about this one? this one has a tracker and it, this means it should be easierfor you

this one has a tracker and it, this means it should be easier for you to find. the cycles are designed by the same company that put the green lights on transport for london bikes. now it is using the same technology to reimagine how douglas bikes could work in uk cities. it's a lwa ys bikes could work in uk cities. it's always on tracker gets yourjuice from pedal power and a solar panel is based on its basket. the marked areas provide virtual versions of the docs and cyclists are encouraged to leave their bikes in them. you can park in the beryl bay, but you can park in the beryl bay, but you can also park it wherever you wish, and pay a small premium to do that. 0ther and pay a small premium to do that. other users will also be paid a small amount to pick up that i can parkit small amount to pick up that i can park it in a bay. if the bike is in the wrong place you can always paint another line somewhere else, no need to put in infrastructure. if working up to put in infrastructure. if working upa to put in infrastructure. if working up a sweat is not your thing, no

need to give up on that might give up need to give up on that might give up on your cycling dreams. california —based electric bike company liime encourages users to cycle a nd company liime encourages users to cycle and park responsibly. it may not work every time, but the company says tipped over bikes send out distress signals to the maintenance team. hopefully they will come to the rescue. but electric comfort comes at a cost. a 20 minute journey will set you back £a while the same one costs just £1 on beryl‘s top up scheme. while biking undoubtedly helps keep a city moving, it is hard to believe that on its own it will be enough to keep us breathing. we are starting to see some interesting things in the way that the road is shared. some examples in cities in america where rather than bike lanes they are starting to have slow speed lanes. so rather than a bike lane where people think only bikes can

use, it is shared space where maybe scooters or other slower vehicles can share. certainly more and more journeys will start using electric power, including our cars. but not eve ryo ne power, including our cars. but not everyone wants to get rid of their old gas guzzlers. so mark has been finding out how they could still be saved from the scrapheap. when we think of electric cars, images of sleek, modern, almost silent automobiles spring to mind. their interiors are spartan and stripped of buttons and switchgear. replaced with touchscreens and acres of space. discovering that this 1953 morris minor is in fact a fully electric car might come as a bit of a surprise them. it has been converted from petrol to electric by the london electric car company, based here in vauxhall. this fine example of a vintage british

automobile has had its fossilfuel drinking guts ripped out and replaced with an electric motor and batteries, a task which is not as simple as! batteries, a task which is not as simple as i am making it sound. matthew set up this company converting classic cars to electric backin converting classic cars to electric back in 2017. park in his garage now isa back in 2017. park in his garage now is a range of customised —— customers‘ different old school cars all being converted, from land rover to lancia ‘s. as a result matthew has to figure out the best conversion solution for each individual car. in a lot of cases ca rs are individual car. in a lot of cases cars are converting that have never been converted before. there are a handful of electric morris minor is in the entire world. the lancia beta behind me, no—one has ever converted that to electric. the first one is the spoke version, we are figuring out where batteries go, how to connect the motor to the gearbox, how much range can make a physical

intake. this morris minorfor example, we have the gearbox, in fa ct example, we have the gearbox, in fact the entire —— intake inversion has been done in such a way that it could be converted back to petrol very easily if the owner so wished. you are getting 100 horsepower... comedian jake‘s morris you are getting 100 horsepower... comedianjake‘s morris traveller is currently in the workshop undergoing conversion. the car itself is 55 yea rs conversion. the car itself is 55 years old, but the electric parts have been salvaged from a modern ness leaf. i balk this car specifically to be electrified. ness leaf. i balk this car specifically to be electrifiedlj always specifically to be electrified.” always wanted morris minor but have awaited grappled with the idea that it is polluting, if i wanted to buy another car it should be an electric car, i another car it should be an electric car, lam another car it should be an electric car, i am very excited about getting a snazzy entertainment system satnav unit from the nissen leaf, i want that in there because it is an old car, but i enjoy toys. i am looking forward to going to service stations on motorways and going and driving

into the bay for electric cars to charge, and watching people look at it, going... that's an electric charger, oh wait! it is an electric car! butjust how practical is a car like this on london‘s congested roads. matthew took me for a spin so i could experience it myself. this car has about a 40 mile range, and thatis car has about a 40 mile range, and that is on the low side as far as i —— electric cars are concerned. that is on the low side as far as i -- electric cars are concerned. that is to keep costs down and it is designed to be a city car. it is a 1950 series to morris minor. its top speedis 1950 series to morris minor. its top speed is about 55 mph. frankly anything over about as myers deputy speaker about as mph is petrified. we are not wearing a seatbelt because we don't have to do, because a car built in that area would not have seatbelt so we are not obligated to install them. so

anything over 30 miles an hour is taking life into your own hands. it has hundred foot—pounds of torque which is about... which is something people think about electric cars, there is a performance there. we find that 40 miles is about a week's worth of driving in london. how long did it take to convert this car?m took about six months. normally we would estimate between 3— six months the conversion based on whether or not we have done it before, how complex the conversion was going to be. how much are we talking about to do this? at the moment we generally suggest a based figure of about £20,000, which is a lot more than we would like it to be. ideally we would like it to be. ideally we would like it to be. ideally we would like to get to the point where you are looking at £5,000 to convert this car. classic cars have several economic fact is in their favour. they are road tax exempt and classic car insurance is often very cheap. electric motoring may be the future, but there is not any reason why

these cars can‘t have the flavour of these cars can‘t have the flavour of the past. mark there. and if you thought that was a bit out there, nick has been to dubai to meet someone with even more outlandish ideas. a land famous for extravagant displays of wealth. towering skyscrapers, gigantic indoor fish tanks, and next? coffee? here at royal coffee and downtown dubai hipsters hangout sipping bruise made from beans roasted on site. patrons are charged a bit more for your regular joke, are charged a bit more for your regularjoke, sure, but the stuff hits the spot. today i am reading an unconnected entrepreneurs set on taking the traditional roasting process to new heights, literally. what about, we could send coffee beans to space, and when they come

back through the heat of the re—entry we can harvest that heat and race these coffee beans. so they wa nt to and race these coffee beans. so they want to load up a capital with beans, striper torok, blasted into space and as it comes back to earth, beans inside a special chamber will roast them up, obviously. he and his partner first have the idea while studying at international space university in strasbourg. why are we a lwa ys university in strasbourg. why are we always trying to stop this heat and prevented, when we could use it and harvest it to do something with. tell me more about this thermal chamber, how would that work exactly? chamber, how would that work exa ctly ? is chamber, how would that work exactly? is it hypothetical or is this real science? it is real science in theory. until we tested really through this coming year 2019, to be able to confirm that the desires and proposal and emulation we are doing is really matching the real data we will get from this test. —— designs. real data we will get from this test. -- designs. is there a need to

roast coffee beans in space?” really hate the staying we should not reinvent the wheel. —— saying. i think someone lazy zs. what is the current proposed cost per cup? why are you laughing? for the last two weeks we have had a lot of speculation from other scientists, our goal would be to bring it to something around $a5 per cup. our goal would be to bring it to something around $45 per cup. there is no way i am buying it for £35. evenif is no way i am buying it for £35. even if this project did not work, for us the january of inspiring and motivating people is not —— is the most important thing. it is not the end product, it is really going to come out as something exciting for making this project. at 40 quid a pipe it is going to be too much to swallow the money. but in city of

expensive tastes it could be their cup of coffee. that‘s it for this week. if you want to keep track of what the team are getting up to you can find us on facebook, instagram and twitter at bbc click, thank you for watching. hello there, it‘s looking like a pretty mild weekend across most parts of the uk, but, as i‘ll show you in a moment, sunshine amounts will vary. now, the last few days have been characterised by heavy downpours, areas of cloud circulating around an area of low pressure, but as we start the weekend, that low is retreating southwards, taking a lot of the rain with it and leaving us with easterly winds. where you are exposed to that easterly wind, parts of eastern england, a good part of scotland, we will have cloud and patchy rain at times. the further west you are with some shelter from the easterly wind, that is where we will see the driest

of the weather and the best of the sunshine. the rain associated with that low pressure continues to pull away south—westwards through the early part of saturday. more patchy rain pushing into the north—east of scotland. in between some clear spells, most temperatures holding above freezing, but some areas starting with a touch of frost. through the day there will be some spells of sunshine but generally more cloud coming in from the north sea into eastern parts of england. cloud spinning across scotland, some outbreaks of rain sometimes, in the north sea coast the wind coming off the sea. elsewhere, particularly where sunshine further west, it will be a mild day, 11—1a degrees, and at aintree for the grand national, blue skies overhead and a bit of patchy cloud here and there. temperatures as the race gets going, and around 5:15, around 13 degrees. it will be western areas that hold onto the clearest of the skies as we go through saturday night, so much so that parts of northern ireland could see a touch of frost. elsewhere, more and more cloud feeding in from the north sea, a spot of drizzle and blanket of cloud holding temperatures between 5—7.

it does mean a grey start on sunday for many of us, and still a bit of patchy rain across north—east england and scotland. moving through the day signs things will brighten up down towards the south, but that could just serve to kick off one or two hefty showers, particularly to the south of the ma corridor. some hit and miss thunderstorms by the end of the day. 17 degrees in london, a little bit cooler further north and east. next week gets off to a mild start, but it looks increasingly likely that cold air will come back in from the north—east as the week wears on. the forecast looks like this. showers towards the south on monday and tuesday, a mild start to the week, but from the north—east things are expected to turn cooler,

temperatures beginning to dip away.
