Now on bbc news, click. This pitstop takes one minute. This week, a city brought to a stop by ransomware. Going greener in india. Electric whirring. We open it up, take the battery out. And does the future people now have vehicles of motorsport sound like this . Without the batteries. Electric whirring. And they use battery as a service. They do 50 kilometres, they pay for 50, they do 100 kilometres, they pay for 100. And so they dont own the batteries, they dont have to manage it. The whole thing is taken care of. 0n four, two, even three wheels, indias eclectic electric is taking shape. David reed on the road in india. Thats it from us for now. Dont forget, if you want us were formula e. Always there for you on instagram, the highest class of competition for youtube, facebook, and twitter. Electrically powered racing cars. We live bbcclick. Thanks for watching. And well see you soon. It is still very young, with its inaugural season taking place in 2014. But its quickly becoming incredibly popular. This is the car the teams race in, it is the generation 2 car, completely Battery Powered but still capable of achieving speeds of up to 174 mph. 0 60 in 2. 8 seconds. Hello. Our very unsettled spell of weather is set to continue as low pressure is still dominating our weather out there at the moment. We know how popular formula i is, but formula e is looking to overtake now this picture was taken it in the world of motorsport. On wednesday by one of our weather watchers in herstmonceux, east sussex. Grey skies there, weve had some big names like bmw, nissan heavy showers around. And mahindra are involved, much of the country has already seen with places taking place all over the world from mexico, heavy rain and we have still got to france, to china, to germany. Flood warnings in force with more persistent rain to come over the next 24 48 hours. We are here at the xl centre which will be home to next years london race. What is interesting is that this now the area we are most concerned will be the first track in the world that runs both outside. About during the day on thursday and inside a building. Is this region, the south east of scotland where there could be 80 100 millimetres of rain falling and with drivers like felipe massa falling over the highest ground. So that means disruption to travel, making the switch to formula e, there is a growing and flooding is likely. Interest in the sport. If you have a look through the course of thursday, that rain really will be quite the car is difficult to compare, relentless, only slowly easing away the car in formula e to the car as we head through the in formula i, the mentality is completely different from one latter part of the day. Championship to the other one. But the idea i really enjoy, but lets take a look at the whole and i am really happy to be part of the uk on thursday, of this championship. Lots of blue on the map. We will have more on formula e later in the show. Lots of wet weather. Across central and northern parts but first i want to tell of england, southern and eastern you about someone that has been scotland, some heavy downpours. Northern ireland having happening in baltimore in the us. A bit of a drier day, because just over a month ago, as does the far west of scotland too. On 7 may, this city of 3 million south east of england should stay mostly dry, people was struck by but therell be a few heavy showers and temperatures not doing great still, only around 11 16 degrees. A massive ransomware attack. Lots of cloud around, really, across the board. As we move through the course of thursday evening and into friday, almost instantly, get this, we keep cloud, we keep the entire citys municipal patchy outbreaks of rain, functions were shut down, probably not as heavy and they have been ever since. Or persistent as the rainfall during the day on thursday. Even now, a month on, but more downpours across england and wales, heavy showers rattling no one seems to know into northern ireland, too. What to do about it. Temperatures below what theyve been in recent nights dave lee has been finding out as those winds are set to fall light, too. What happens when hackers take down an entire city. Low pressure still with us as we move through the day on friday, itsjust drifting towards the north west a little bit. Baltimore is a vibrant city not as many isobars on the map as there has been recently, of the us east coast. Around 10 Million People live here. So not quite as breezy. But through the day on friday, its another unsettled story. But right now it is in the grip again, a lot of cloud to start the day. Of a massive cyber attack. Some showery rain here and there across england and wales and some further rain showers piling this malicious attack, this virus, in across parts of western scotland forced city officials and northern ireland, too. A little bit more sunshine here to shut down some by the time we get to friday crucial services. Today is the 10th day of a crippling afternoon, lifting temperatures to about 13 19 degrees, cybersecurity attack not quite as cool as they have been. On baltimore city. As we head through into the weekend, city leaders say the fbi has opened then, still a fairly unsettled story. On saturday, weve got some showers a criminal investigation. Technicians are working in the west but eastern parts of the uk, sunny spells and just one to resolve the issue, or two isolated, scattered showers. But until then many files temperatures starting to creep in the citys Computer Systems are unusable. The citys interim mayor, who is less than a month in the job, up by a degree or so, faces a crisis. Our team is working very hard. I cant give you a timeframe, theres still a noticeable because you know, when the virus breeze around on saturday. And then as we look further ahead hit, we had to find out into the course of next week, where it is throughout the whole system. Eventually we should lose the showers, at least the hackers are demanding 100,000 from the south. Worth of bitcoin to set still fairly unsettled across the north, but temperatures the citys computers free. On the rise. Bye bye. I am just heading to one of the municipal buildings here in the city, a place i am told where people are having to go in person to pay things like parking fines, which they would normally be able to do online, but of course the website isnt working. I am expecting to encounter some rather fed up people. I think ultimately they need to pay the ransom, but thats just me. But i know you dont want to inspire other people to do the same thing, but i think they need to solve it, because they are losing a lot of money themselves. It is a big inconvenience, but you gotta get it done, so. One of the most disrupted industries has been real estate. The systems used to put through sales was knocked offline. Anybody who was having a transaction, they were not able to go through with it to the settlement table, meaning that everything was delayed home ownership, commissions being paid to the real estate agents, fees being paid to lenders as well as title companies. A manual workaround has been put into action, but realtors are still nervous about the long term effects that this is going to have on the housing market. There could be an added kick in the teeth. They were early reports that hackers may have used a flaw not discovered in china or russia, but perhaps here, just 20 miles away from baltimore. The New York Times reported that the hack may have used an exploit known as eternal blue, developed by americas own National Security agency, the nsa. The nsa however denies its exploit was used, and even if it was its, advisers argue that baltimore should have protected itself, as a Security Patch for the vulnerability has been available for more than two years. So focusing on a single exploit, especially one that has a solution through a patch that was issued years ago, is really shortsighted. Vulnerabilities will continue to be welcome to bbc news found, doing the basics is required broadcasting to viewers for responsible network in north america and around the globe. Administration. My name is mike embley. Our top stories regardless of how exactly the hackers breached baltimores donald trump declares open defences, Security Experts say he would accept information from a Foreign Government about political rivals it speaks to a bigger problem. In the next election campaign. Unfortunately baltimore citys it this is the scene operations are not in great shape. Live in hong kong the city is underfunded where the authorities have announced for its it department. The closure of some government it is a man made disaster. Offices for the rest of the week. Its quiet, currently, after the storm of the past few and it is a disaster days. There were violent clashes on wednesday against that is the result of negligence a controversial extradition law. And of putting things off until tomorrow. So im on my way now to city hall, to meet with the woman tasked all it has done has made people more with leading baltimores angry. They are trying to rake recovery from this attack. There is talk that they will apply through the Police Barricades over for federal emergency funds, there and things are being thrown. That is the same thing the entire situation has become a as if there was a big flood or some other natural disaster. Lot more baltimore, like many governments, faced challenges in terms of resources and systems being antiquated, that may make them vulnerable to these types of attacks. What our city has shown is that our employees are willing to work really hard to find ways to keep the operations of City Government moving, and to support our citizens and our employees, and that is what we are doing. The city has said it wont pay the ransom, but more than a month on now, Recovery Efforts are still ongoing. The eventual cost will run into the tens of millions of dollars, and unless millions more are spent bringing the network up to scratch, it could happen again at any time. Hello and welcome to the week in tech. It was the week that apple pulled the plug on itunes, leaving separate apps for music, podcasts and tv in its place. Amazon said it would be making deliveries by drone within months. Its new quieter prototype can carry 5lb packages for up to 15 miles, and can identify people, dogs and even avoid clotheslines. And the sky isnt the limit for elon musk. He is facing a growing backlash against his plans to launch 12,000 spacex satellites. The International Astronomical union says that too many satellites in the night sky could end up hindering rather than helping space discoveries. Spacex launched its first 60 satellites last month. Lab grown patches could help your heart keep beating after a heart attack. So say scientists at imperial college, london. These thumb sized strips grown out of human stem cells are programmed to turn into working heart muscle. They have now been deemed safe for human trials. And finally, it seems our travel could getting a bold new book. This concept plane has cabins in its wings, and is designed to use 20 less fuel. Thanks to a cash boost from klm, a small model may be flying this 0ctober. Now, formula e is notjust a competition between electric powerhouses. It is also a testbed so the teams can further develop the tech in these racers. The idea is that this tech then filters down into everyday electric road cars, in the same way that other motorsports have influenced petrol and diesel vehicles. But one of the main features of formula e is that all teams have to drive this car, they are not allowed to change anything about it. Except for one thing. So what is that . Kate russell went for a spin in berlin to find out. Woohoo this years formula e season has been a beauty pageant for the latest in electric car tech. As Second Generation racecars eat up the tarmac with more power than ever before. I was one of a handful ofjournalists who got to drive a generation 2 car for the first time on a track, following the berlin e prix. With 25 more torque and 25 more power than the gen 1 cars, gen 2 goes 0 60 in a blistering 2. 8 seconds. The powertrain is what converts the electricity from the battery into power to drive the wheels. And what they learn on track goes directly into the production vehicles. The teams all have the same core hardware, so eking out a winning performance is about tuning the powertrain. There is also more race strategy this season, as battery range has almost doubled meaning no need for a pitstop, as long as you can manage your power regen over the 45 minute race. Coasting, that is something we do during the race. We have to use our energy most efficiently, and then using the regen because you can slow the car down incredibly well by just using the regen, and not using mechanical brakes. And in a move to make the sport more exciting, the fia has added an engine boost feature reminiscent of triggering power ups in a video game. Basically you have to go off the ideal line to trigger this attack mode, where you have more power, 25kw additional power, during eight minutes. And if somebody is right behind you, it means they will likely overtake you. Then you will have to overtake him again using more power. So it is like playing chase while driving. The other striking change for season five is the look of the cars. And lets face it. It looks too much like the batmobile not to fall completely in love with. With the combined look and sound, it does feel a little like driving into the future. Wow. And new to formula e this year is the Market Leader for electric consumer cars. We were able to use a lot of our knowledge in the production side to come racing. Of course racing will help us develop future technologies, but we really wanted to demonstrate what was capable today. See how much of this tech the commercial cars have packing. Now i could drive around the car park in a road car for this bit, but. Has someone gone in the wall and the exit. This season jaguar launched the i pace e trophy, racing on the same city circuits, and well, it would be rude not to, really, wouldnt it . This i pace may have been stripped down for racing but it is the same basic car you can drive out of a showroom. The road car is focused on comfort and driver ability to use it every day, whereas this is a pure race car. And Lessons Learned on race day are vital for future innovation. Which is why so many carmakers want in. What we hope is that season one, we focus on development of the race car, and then season two, three, beyond, we can bring what we learn from the race, or the race track, back into the road car. The same engineers who developed the i3 and i8 powertrains have developed our motor on the formula e car, so it is really directly related. Like their formula e siblings, these cars are quick and quiet. You said there is no frills, you can hear the noise of the track going under the car. You are able to hear a lot more of what the tyres are doing and almost what the brakes are doing as well, so it adds an extra dimension to it. And after spending a day on the track here in berlin, i am going to look at electric road cars with a lot more respect in future. Wow. That was kate russell. And that was amazing. Now, being only five years old, formula e is still relatively unknown to some. And being born in an age when formula one is arguably the most well known motorsport and with most of us buried in our mobile phones these days, it could be difficult to attract new fans. However, they are using your phone in theirfavour. 0mar mehtab takes a look at how that has been working out. Youtube, twitter, ghost racing, and the formula e app. These are the four apps that formula e are using to try and reach a new younger audience online. So how are they doing that . Lets start with youtube. We all know how massively popular it is, with over 2 billion monthly logged in users checking out all kinds of content. Thats a lot of new potential fans. And so formula e want a piece of the action. At the beginning of the season, i tagged along to watch formula es new live show, voltage, being streamed. Its their attempt to introduce a younger audience to the relatively new sport. Famous youtubers present the show and give live race commentary. A lot of young people dontjust sit and watch one thing. Theyll watch something on their phone and watch something on their tv at the same time. And thats what i think makes formula e innovative is, as a sport, they dontjust go take that, thats what youre given. They listen to the audience and say, right, what do you want to see more of, you know, do you want to see in the drivers cabin, or do you want to see hear more from the guests . Well, that was the idea. But the show was canned halfway through the season. Next up fanboost. Before a race fans can vote for the favourite driver via twitter or the formula e app. The five drivers with the most votes get a five second power boost, which could be crucial to victory in a really tight race. But not everyone is a fan of fanboost. When kate asked online what you thought of it, some of you thought it was ok, but the majority of you thought it was a popularity contest. I mean, this persons only tweets are to vote for one driver. So is it subject to abuse . Should fans have this much input in a race . So lets finish up with probably my favourite out of all of them and what i feel is the most engaging, ghost racing. Fansjoin in using the smart phone or tablet and race against the drivers in real time as the e prix is taking place. Now this is something that hasnt been done before. You cant go and race live with other drivers in any other sport. You just have to have pretty good wi fi at home to do with us. Thats the only thing you need. We equip the race cars with a gps decoder to so we know exactly where they are and then we ingest the data from the race cars and the scenery and we ingest you as the ghost racer into that live cgi feed. 0ur signal, the live cgi feed is faster than broadcast, because broadcast generally has a satellite and were online. So there is no latency. Although formula e is hoping this will be enough to attract new young fans, building a following online isnt as easy as it seems. This is brian hamby, otherwise known as the gaming terroriser, who knows a thing or two about hitting the right notes online. The best tool in youtube is your community. If you ignore them youre not going to know what they want. So when youre trying to just, you know, lets just pay to get these people to come on, and then its going to work its not. Its not going to work. Kids now are not stupid, theyre not dumb. They can tell when things are being pushed down your throat. Natural promotion works so much better than an obvious brand integration. Who is coming in quick . While formula es attempts to connect with the new audience havent exactly hit home, the sheer number of potential fans online means you can bet they will keep on trying and trying. Back in berlin, the e prix is also home to the first green tech festival, founded by former f1 World Champion nico rosberg. One thing that remains is my passion for innovation and innovative technologies. Thats been the same in formula one. And im finding it now in these sustainable technologies, these green. Im so passionate about the innovation, the pioneering thats happening there. 0n show here are some greener ways to travel. Like this fully electric ship that can travel up to 100 nautical miles on a single charge. But some things are just, well, conceptual, to say the least. This airbus drone is supposed to lift cars out of traffic and drop drivers to their destination. Theyll have a range of 30 miles. But it may take more than these to solve some of the pollution problems that are out there. Fossilfuelled cars, bikes, and buses are turning some of indias teaming cities into snarled up and smoking mega jams. In fact, according to greenpeace, 22 of the worlds most polluted cities are in india. Now, flogging electric tech to india is proving a tough sell. But inroads are being made. And david reed has taken to indias streets to find out how electric four, three, and two wheelers are having an impact. Its so nice to be back in mumbai. Its always on the move. An outfit called glyd, which is associated with the indian car manufacturer mahindra, has Just Launched an uber style car service. And the entire fleet is electric. I met up with a regular customer. Its absolutely fantastic. Just about anything that you want in the car is there. There are tv screens. Yes, you have in car entertainment available. In flight entertainment. You have wi fi, you have Video Conferencing facility available in the car. Its like your office on wheels. So why electric . The fact that our cities arent exactly low on pollution means that every vehicle running on petrol or diesel adds to that pollution. Would you ever buy an electric car . I would love to. The only challenge here really is infrastructure around. Which means you dont have enough chargers, charging points. Glyds a good mobile showroom for mahindras cars. 00 22 50,346 2147483051 48 09,888 theyre a tough sell 2147483051 48 09,888 4294966103 13 29,430 because of the recharging issue
