3:30 am
drive against what he called "an explosive increase" in leaks of classified government information under president trump. four people have already been charged and mr sessions said he would not hesitate to order more prosecutions. a british computer expert has appeared in court in the united states, charged with creating software to steal bank details. lawyer representing mark hutchins say he denies all the charges against him. prosecutors insist he has admitted writing and selling malware code. mo farah won gold last night at the world athletics championships. it was in the 10,000 metres, his last competitive race at the distance. natalie pirks followed the action in stratford. this was the scene of his greatest victory.
3:31 am
five years on, london and his family were ready to watch britain's team get off to the perfect start. one more time for mo farah. he adopted his favourite position near the back of the pack. it seemed there was a tagteam of other nations working together to keep him out of the hunt, lap after lap he stayed out of trouble, biding his time, even asking the crowd for more passion. he is realising it. the gauntlet had been laid down. he has before, he has in london... but when he went into the final lap in the lead, it was never in doubt. london's crowd, his crowd, brought him home. what a race, what a legacy. i got a bit emotional at the start, i had to get in the zone and yeah, it has been amazing. it is not only sir mo farah who is saying farewell, the fans are gearing up to say goodbye to the sport's greatest entertainer.
3:32 am
usain bolt has not been lightning quick this season — perhaps he is saving his best. here he comes, and there he goes. the time was not spectacular but it didn't have to be, strolling through to tomorrow's semifinals where he is aiming for his 12th, that's right, 12th, world title. london loves him. i'm really feeling the love here, i really appreciate it, and always happy to be here. sprinting has suffered more than most from the spectre of doping. today, retribution to the likes of the athlete who collected two bronze and an upgraded silver as she and another relay team members were cheated out of past games.
3:33 am
and for brits through to the semis of the women's 1500 metres including laura muir. she looked calm throughout, she will need to be — britain has never had a champion in the event. but it has yet another in sir mo farah, the greatest athlete britain has ever had. in a few minutes, it'll be time for the film review. but first, here's click. they're ugly, huge and they ruin the landscape, but we do kind of need them to get from a to b. but sometimes a road can be more than just a road. and that's the idea behind a french
3:34 am
government backed initiative using the massive space given over to the transport network to also capture the sun through solar roads. i mean, look at this road, what's it doing right now, it's looking straight up the sky. and it's estimated that even busy roads can see the sky for 70—90% of the time. but it's not all plain... sunning. the problem with putting photovoltaic cells into roads is the slightest bit of pressure, the slightest bend, and... so the cells are stuck onto slabs and covered with crushed glass and a translucent resin. at the facility near versailles, in france, these seven millimetre thick panels are being tested for their strength and durability so they can withstand heavy traffic as well as ensuring that they aren't slippery. we have the cell and on each face we added polymer to increase the stiffness and the durability
3:35 am
of the cells itself. so do they bend or are theyjust resistant to bending? yes, of course they bend, butjust a little bit. so it resist. the costs, though, are proving high. although the panels can be laid over existing roads, this one—kilometre stretch in normandy covering 2,800 square metres came in at 5 million euros. that's an estimated 4—6 times the price of covering the area with conventional solar panels. currently, yes, of course the cost is quite high. it will be within at least one year. after concerning the interest it's really a political approach. critics have questions about the viability of panels on busy roads and the efficiency of laying panels down flat on the road surface. the angle or the tilt angle of the panels will also influence the efficiency. if we have them lying on the floor, on the road,
3:36 am
then we are influencing the tilt angle. one possible advantage of having the panels flat on the ground is that in the future they could be used to charge electric vehicles as they move along the road. and charging vehicles as they move is another idea on the horizon. developed by qualcomm technologies, this 100—metre stretch of dynamically charging road is also being trialled in versailles. i do like the idea that although the road networks have obviously been a major source of the planet's pollution problems, they could also be, in the future, one of the solutions to the planet's energy crisis. and with the uk government phasing out diesel and petrol vehicles, renewable transport solutions like this mightjust be the ticket. stationery induction charging works like wirelessly charged phones, producing a magnetic field that's converted to dc power. though this technology has been with us for a while, dynamic roads
3:37 am
are an exciting development. how accurately do you have to park this thing so the two pads are aligned? at the moment we're talking about an area the size of about a dinner plate, as long as that's aligned on both sides you should be able to send the charge through that. you have a line of these on a road and you simply connect them all up and that would effectively give you a charging road. as long as the car was obviously aligned with that, and the technology was all linked and synced up, the car could actually charge while it's driving along using exactly the same principles and technology. critics though worry about the infrastructure cost of dynamically charging roads. 0thers point to the rapid developments in electric vehicle battery capacity that may remove the need for electric cars to charge while on the move. but if solar roads can be made cheaply enough and withstand heavy traffic, this could be one to watch in the not too distant future.
3:38 am
hello and welcome to the week in tech. it was the week that the script for an unseen episode of game of thrones, as well as those from other hbo shows, was leaked online by a group of hackers. an new version of bitcoin was mined for the first time as the crypto currency split into two. and the us navy's launched its first fighter jet powered by electromagnetic energy. the high—tech, high speed, hyperloop one has completed its first journey. a test that propelled this pod through a tube in the nevada desert at 192 mph, edging closer to its eventual aim of one day transporting passengers at speeds of up to 650 mph. meanwhile a security researcher managed to hack an amazon echo, making it possible to remotely
3:39 am
stream audio from someone‘s device. the attack could only work on pre—2017 versions though, and physical access to the echo is needed first. and finally the team behind the hand—held spray printer painting device, which we showed you a couple of months ago, have developed a robotic version that made it possible to paint this giant masterpiece on an abandoned power station, using five different colours at once. the sky's the limit. i'm scott helm, here to give you a 101 to black hat, bsides and def con, which all happen during one crazy week in las vegas. this is a very, very popular course, we've got some of the latest stuff that we've found in our own hacking that we do for clients and we put it into the class. the good guys have got to learn it because the bad guys already do. i've embedded some code into the page and then when you load the page it puts that message up,
3:40 am
that it's not supposed to do. it was a nice introductory level course. so obviously this could be used for harm and the flip side of this is, if you were setting up to be a cybercriminal would you come to a formal conference like this and register to do a training course under your name? or would you go and learn how to do this on the dark web somewhere else? i don't think we would really expect to see criminals coming here to learn how to be criminals. so we are in the vendor hall right now. this is where all the different companies have their stands, they can demo their products. this represents what they do inside your network, in that an attacker now doesn't know where the real target is and which one to attack. i don't know where to look. tell me if i'm doing it wrong. this in the front? hang on, waita minute... one, two, three, go! top three tips? we're in the desert, drink plenty of water. get a goodie bag and fill it with swag. and don't use the wi—fi. so we've just checked in b—sides, i have my bag, everyone that attends
3:41 am
the conference gets a little bag of goodies so we're just going to take a look. got a few stickers here, the little hawaiian necklaces, a bsides beach towel. it's very corporate, it's very kind of official and formal. this is like a much more relaxed setting, it's much more enjoyable. the opening key note is taking placejust behind me, and we're going to go and take a look around the vendors around the outside of the chill out room. scott, what did you just do? so, the wi—fi network is here is monitored, and the screen behind me shows you things that people are doing on the network. so we managed to just get the bbc click logo and rory up on the big screen. this is a tool called a doppler. the whole idea is it's analysing the network, and then carving out images real time, and displaying them up for everybody to see.
3:42 am
so anything that anybody is looking at on the network, we can see as well. —— i found some friends. i found some ex—colleagues of mine from england. so which talks are you going to? i'm going to the banking on insecurity nets, which you are banned from. as members of the press. yes, so being members of the press at bsides, we can't go into the underground track, which is no press, no filming. most people don't even use their real names in the schedule, and unfortunately we're banned, we can't go in there. it's like a party in here. i can't hear anything. it's a tech conference, it's a hacker conference. people often think it might be less sociable, but this is where most of us do our networking. we're in the middle of filming and somebody has just hacked the pa system in the hotel. thank you. we made it, we got one. effectively, this badge is like a tiny computer, and i can make it do like really cool stuff. flames. yeah, we have come to the chill out
3:43 am
zone just to take a little break. i bumped into an old work colleague and friend of mine, andy. he's a goon here, at def con this year. most people probably won't know what being a goon is, so... so being a goon is basically the enforcement of fun. so we were walking the corridors earlier today, and we heard some numbers being thrown around, in the region of 50—60,000 attacks a day are launched against the def con network, is that accurate? it's what you would expect of a hacking conference's network. there's no official challenge, but hackers going to hack. federal agents attend the conference dressed in plain clothing. there's 30,000 people here. it's easy for them to blend in, and there's a running competition every year to try and spot and identify federal agents. my guesses would be they're looking out for people they may need to keep an eye on, and the other side of that is talent acquisition.
3:44 am
so we were watching somebody get their first implant. are you nervous? yes, a little bit. i'm kind of wondering, how much it will hurt. oh, that felt weird! i am going for the nfc chip. i'm going to apply a little bit of pressure. it was literally like something poking around inside my hand. my front door lock at home, i'm going to replace it with an nfc lock, and it will sense the chip in my hand and unlock my door forjust me. when you're at def con, you just never know what is going to happen next, it could be a complete surprise. you will find more on privacy, security, and hacking on our website and social media as part of bbc media's hacking season. that is the short version of click for this week. the full version is online. thank you for watching and we will see you soon.
3:45 am
hello and welcome to the film review on bbc news.
