this is bbc news. the headlines: president trump says he would welcome a full trial in the senate if the house of representatives votes to impeach him. he told fox news the process would help him get re—elected. mr trump added he'd like to hear from the whistleblower whose report led to the inquiry. with less than three weeks to go to the british general election, the leaders of the four biggest parties at westminster have been given a grilling by members of the public in a special edition of the bbc‘s question time. there were uncomfortable moments for them all as they made their pitches. a man who strangled a british

backpacker in new zealand and hid her body inside a suitcase has been found guilty of murder. grace millane was found buried in bushland outside auckland last december. the 21—year—old was killed after a night out on the eve of her birthday. now on bbc news, it's click. this week, could this be the future of gaming? move over vin diesel, we are about to go fast and furious. and are you ready for a debate with a robot?

streaming services have changed the entertainment landscape. they are taking bigger and bigger chunks from the dvd market. they have completely revolutionised the music industry. and they've got terrestrial tv execs quaking in their expensive boots. but what about streaming video games? well, that's a lot harder, because you need to make the game responsive and playable. so could streaming ever kill the games console? this week, tax giant google launched stadia, a brand—new games streaming platform. —— tech giant. you would no longer need an expensive computer or the latest game console to play the best titles. in theory, you would only need a good wi—fi connection. or at least, that's the idea. much is like has been putting stadia through its

paces to see if it lives up to the expectations. google stadia does away with one of these, a games console, and replaces it with one of these, a chrome cast ultra. if you wa nt to these, a chrome cast ultra. if you want to play a game on a tv, that is, stadia also allows you to play ona is, stadia also allows you to play on a tablet, computer or phone. in theory it is capable of producing 4k visuals. it plugs into the back of the tv and then connects to a router. this then makes a connection with the data centre. this controller communicates with the router via wi—fi and allows me to actually play a game. streaming again is more difficult than streaming video, because with video you have data travelling in one direction, from the server to the viewer. with a game, data travels both ways. the inputs i am making to control the game travelled to the server control the game travelled to the server and the graphics displaying the effect of my input have to come back to me. this is where a potential problem could occur due to a thing called lag. if the inputs do

not match up to the graphics, the game becomes impossible to play. google claims its data centres use special tack which helps avoid this, as well as recommending that you as are capable of receiving particular internet speeds. —— special tech. so the minimum required for tim on back to work as an internet connection of ten and bps download and one mbps upload speeds. i have everything connected by wi—fi. are we ready now to consign our consoles to the bin? initially, no. because as you can see, performances, well... it is a little bit a little bit like you. —— a little bitjuddery, a little bit laggy. and nowhere near as smooth as you would expect from a console. and now the connection isn't stable so the game has stopped. i am inside the game has stopped. i am inside the bbc building using a router which should be more than capable as far as this is concerned. so what is

stadia like out in the real world? so we take a quick trip across town to jack. i have come to a flat in north london, and i've got stadia set up here. we have quite a good internet connection here, about 20mbps, well inside the specification that should work with this device. it is a little bit of a faff to get it set up, because each one of these things, the controller, the phone, and the chromecast ultra which is plugged in, has to connect to wi-fi which is plugged in, has to connect to wi—fi individually. it is quite impressive. it is smooth, it works, you are playing the game. everything is working properly. but after a little bit of time playing, i've encountered quite a few issues with performance. graphics sticking... this is actually working quite well now, it has actually settled down quite a bit. i should now, it has actually settled down quite a bit. ishould point now, it has actually settled down quite a bit. i should point out i couldn't get stadia to work on any public wi—fi, though, the kind of

stuff you find in cafe ‘s and bars. there are a number of videogame streaming services already available, but stadia is perhaps the most ambitious. so far it has a list of 22 titles at launch, but only one exclusive, and while games like tomb raider and destiny to our solid titles, they are not exactly brand—new games we have work to do. but perhaps the biggest challenge to google comes from microsoft, with its games streaming offering, which was on show at a recent xbox event. microsoft's response to videogame streaming is project x cloud. i am playing halo, the master chief collection, on a mobile phone over a wi—fi connection. the crucial difference, i suppose, wi—fi connection. the crucial difference, isuppose, between disservice and google stadia, is that this is currently in its phase and microsoft is taking a very cautious approach. we are early in this technology. we believe it will

ta ke this technology. we believe it will take many years before this technology becomes mainstream. the best place for you to play will be on your local device connected to your tv, and that will be true for many years. the same thing for a gaming pc. the local computer capability but you have, you are not dealing with internet irregularities, you are dealing with a dedicated device which is meant to go a dedicated device which is meant to 9° play a dedicated device which is meant to go play those games, connected to a display device which is probably the best display device in your house. when it does work it is a minor miracle. both of them are. it is amazing when you can just switch devices on the go, jump from your tv to your tablet or your laptop, you know, that barely runs microsoft word and then suddenly you are playing destiny two on it. that is amazing, when it works. but it is a little off in the distance before it is sort of universally accepted as the new way to play. there has been a lot of confusion about stadia's pricing, with lots of people thinking it is a netflix for games.

it's not. basically, the user pays a subscription to access the service. all the games must then be purchased in order to play them. it costs £69.99 a month for a stadia subscription. this allows users to use the service and play games at 60 frames a second. there are a host of features for stadia which are not ready at launch, like sharing clips to youtube. but on this evidence, videogame streaming is surely the future. the problem is, today's technology isn't quite up to the task. that was mark. now, last month we spent a whole episode of click looking at all electric class, and as part of that, we showed you just how quick electric cars can be. —— electric cars. this was lower in eight has low saloon car out gunning a lamborghini. electric ambitions don't stop in supercar territory. no, several manufacturers are working on electric hybrid cars.

this is tesla's vision, this quarter of $1 million 2020 roadster is due next year. and here is the rimac c2. it has the equivalent of 1888 horsepower, and it has a claimed zero to 62 time of 1.85 seconds. and a base price target of $2 million. but both of those cars could be outgunned by a british designed hypercard like none other, and it is even more expensive, too. —— hyper—car. dan simmons has been to hassle in norfolk for what is hoped to be the rebirth of a legendary sports car badge. he built his first carforfun. no—one sports car badge. he built his first car for fun. no—one knows sports car badge. he built his first carforfun. no—one knows why, but he called it a lotus. since the 50s, lotus has been producing lightweight ca i’s lotus has been producing lightweight cars designed to thrill, from the

classic 60s elan to formula 1. 23 speed races are on the grid to start the european grand prix. lotus has been specialising in affordable sports cars, offering two, three, or even 400 horsepower. but now, with new investors, it is first for a into electric is as i watered willingly expensive as it is powerful. —— eye—wateringly expensive. and nobody has seen anything like it. this car is the first all british electric hyper—car. it will be the most powerful production car in existence when it goes into production next year. it is a huge statement of intent. announcing that lotus is

back. we have four motors to deliver 2000 ps back. we have four motors to deliver 2000 p5 in back. we have four motors to deliver 2000 ps in total. that is german for 1973 horsepower. to do that in this packaging we have had to take existing technology and radically improve on it. what are engineers and designers have achieved is something which looks beautiful, but have done it as a form through function. every part of the design has a use. these are the first pictures of the avaya in action on a test track. while it is still being tinkered with, it is in camouflage paint. the new poster child for lotus is not just paint. the new poster child for lotus is notjust a pretty picture. the avaya will have some truly astonishing abilities under the hood. so, there's no gears. there is a single box which means we have com pletely a single box which means we have completely linear reconciliation

form, from zero to over 225 miles an hour. what that does do, it gives us unbelievable acceleration. so we can go from zero to 300 limiters in our in significantly less than nine seconds. —— kilometres an hour. in significantly less than nine seconds. -- kilometres an hour. the low seating position is afforded by placing the 600 kilograms of batteries in a pyramid formation behind the driver's seat. liken it mounted engine. —— like a mid— mounted engine. —— like a mid— mounted engine. —— like a mid— mounted engine. those batteries are special, too. after recharging 3000 times of mixed driving modes, performance dropped just 10%. and in this car, with a conventional 350 kilowatts charger, you can go to 80% in12 kilowatts charger, you can go to 80% in 12 minutes kilowatts charger, you can go to 80% in12 minutes and kilowatts charger, you can go to 80% in 12 minutes and 100% in about 16 minutes. we are working with partners to develop ultrafast charges, which means we could charge the same time in less than nine minutes, up to 100% in about six minutes, up to 100% in about six minutes, up to 80%. that would be truly world—class. that's all very well, down, i hearyou truly world—class. that's all very well, down, i hear you say. truly world—class. that's all very well, down, i hearyou say. but

where do i put my luggage? well, how about the carbon suitcase that you fit just here about the carbon suitcase that you fitjust here inside the driver ‘s door? there is also one on the passenger side, so you are not fighting for space. the downforce on this car can be increased fourfold, with the rear wing and undercarriage adapting according to conditions. out £2.2 million each, just 130 avayas will be made, starting next year. but the tax behind them will be around for a long time to come. —— tech. hello. welcome to the weekend tech. it was the week iran a near total internet blackout following protests against petrol prices, leaving almost 80 million people without online access. britain's conservative party came underfire for

you don't exactly know what you'll get as a reward... well, that's addictive too. to be clear, we want that, right? to be very clear, that's what makes a product engaging and interesting and we're going to say netflix, please make your shows less interesting and apple, please make your devices less user—friendly? of course not, we wa nt user—friendly? of course not, we want them to be engaging. a few years ago, this man wrote hooked, a book that details these techniques to make company products more habit—forming but he said he hoped they would be used to form good habits. tech companies have been using these techniques for a long time and the idea behind the book was to democratise those techniques, why shouldn't companies use this to form healthy habits? ididn't like use this to form healthy habits? i didn't like these for the gaming companies and social networks, they knew them, but i wanted companies like fitbod to get hooked in the gym, and kahoot to get kids hooked

to classroom using so we can do this to classroom using so we can do this to get good techniques. whether hooked or facebook, many of us are feeling hooked and now a.l. has written an antidote. indestructible, a book to help us break our smartphone habits. poacher turned gatekeeper? maybe. today it is social media, yesterday it was games, the comic books, things people said were melting our brains and addicting us but none of that has really happened. his book deals with suggestions on how to resist the internal triggers like boredom or foam how to resist the internal triggers like boredom orfoam that how to resist the internal triggers like boredom or foam that cause us to reach for our phones. i think we all have to face up to the fact that these big corporate moneymaking corporations are going to want to use every means possible to make us use every means possible to make us use their products more. that's just correct. you're right. really? they

don't want to create addicts, they wa nt don't want to create addicts, they want lifelong users, so it's a competitive threat to these businesses if people say, "this product is hurting me", and that's what people do with time if a product hurts them, we're not stupid and not puppets on a string, if a product sucks people will stop using and find an alternative. in ten yea rs, and find an alternative. in ten years, where do you think we will be? if you think the world is distracting today, wait a few years and that's why it is crucial, crucial to teach our children to become indestructible. that is the skill of the century. speaking of those skills, i've been taking a look and some of the apps and functions within our phones to help encourage us to spend a little less time looking at these screens screens. so how about the idea of being rewarded for the time that you spend away from your device? now, i get the idea that an app to do that is kind of ironic because it's on the phone, but apps like forest aim

to create the right feeling that makes you want to not use your phone. the aim here is to build a whole forest one tree at a time so each time you want to take a break from your phone, you set how long thatis from your phone, you set how long that is for. could be half—an—hour, could be ten minutes, and then you tap on plant. so a tree is being planted as long as i spend that time away from my device. every time you're tempted to go back and check your social networks, tempted to go back and play that game you're so addicted to, well, you have to actively tap give up to do so which psychologically does make you want to put the phone back down and carry on with what you're doing. the ultimate aim here is to create a whole forest and, at the same time, you can track your progress to see each day, each week, each month how long you managed to stay away from your phone each day. you can even set up group tree planting where if one person falters, you all fail.

another way that you can spend less time connected to the internet is actually reducing the amount of time you can connect to your wi—fi. think of it as like parental controls but for yourself, and this can be done at ruto level. this is what's known asa at ruto level. this is what's known as a mesh wi—fi system. it allows you to upgrade your home internet function, including setting rules about the times you can connect phones, tablets or computers to the web. and then you connect all of your gadgets to the device, so you can select various functions. you can add antivirus but you can also go in and change those all—important timings. of course, the one robin with theirs is you could switch to mobile data, so to avoid that temptation, you can switch mobile data are thin those apps that are going to tempt you the most. but for

those moments when fiddling on your phone seems pretty unavoidable or simply irresistible, then another option is to switch it to greyscale, as those apps are going to look a lot less appealing, so you're likely to wa nt lot less appealing, so you're likely to want to spend less time using them. creating the iphone shortcut is easy, and once you have, triple tapping the home button allows you to switch the function on all of. it's a little bit more complicated on the android device, though, as you do need to enter developer mode. realistically, all of these options do require a little bit of willpower still, and if you had enough, i guess you wouldn't need them in the first place. but hopefully they are somehow. right now i think i need to get back to checking my phone. —— some help. keep scrolling, lara, keeps rolling! now, computer scientists around the world a re now, computer scientists around the world are working on ways to make

artificial in indistinguishable from humans, with varying degrees of success steadily but one way this is being tested is in debates between humans and computers, and this week ibm's aia system was on stage at cambridge university and jane croad state was in the audience to see the results. cambridge union is the world's old est cambridge union is the world's oldest debating society. in the past it has hosted winston churchill, the dalai lama and theodore roosevelt but tonight's star guests are not human but artificial intelligence. the next issue is bias... ibm's project debater is the first of its kind in the world and can debate humans on complex objects. in another world first, it is here tonight to help to humans debate the motion ai will do more good than bad. project debater, these take the floor.

ai will not be able to make a decision that is the morally correct one. two project debater ‘s are present in this this single avatar using a female voice and each team's debater presents the opening arguments, which has been determined from over 1000 contributions, something ibm calls speech by crowd. we will demonstrate how ai will automate repetitive tasks and the next issue will show how ai will create new jobs. the system solves the responses into meaningful groups and identifies central themes and the ai generates a narrative from what it deems the most relevant information. then the human team members take over to continue the debate. they peered deeply into our soul because of the amount of data we trail on an everyday basis. with ai, it's absolutely crucial stop ear? because without data, there is no ai. absolutely crucial stop ear? because without data, there is no al. the fa ct without data, there is no al. the fact you have an ability to collect information or get evidence and... with the other side is taking things

humans already do as part of debating, enhancing abilities to do things much better. some abilities will be able to be pushed much further with the technology. project debater first faced debate, the debate champion in february in san francisco. and while losing the debate, the audience felt they had learned more about the subject from the ai and from the human champion. about the subject from the ai and from the human championlj about the subject from the ai and from the human champion. i think when you have access to far more information, it changes the way in which you think about the topic. humans augment that by being able to talk about some of the emotional and moral issues, and i think at least at this stage, artificial intelligence is behind. the future is in intelligence is behind. the future isina intelligence is behind. the future is in a synergistic collaboration between the system and humans, and not in replacing humans. you never think it will be sophisticated as a human in developing arguments?” believe when you're actually trying to use this technology, you should do that in collaboration with humans. in the end, the ai assisted

debate was a tight run contest, 51% voted against the motion that al would do more harm than good with 48 cents voting for and 1% abstaining. and ever so slightly upbeat view on the future of human interaction and ai in cambridge. that was gen in cambridge and that's it for this week. don't forget that we live on, altogether, youtube, facebook, instagram and twitter, @bbcclick. thanks for watching and we will see you soon. hello there. rain is the main concern over the next 24 hours. there are various met office warnings warning about that persistent rain, but there could be some travel disruption, even possible flooding.

it's certainly been wet through the evening and night across the south—west and wales and across northern ireland. that rain's been moving northwards, so the warnings come into force as well through the midlands and then northern england, eventually parts of scotland too. so, given that we've already had well in excess of what we'd normally see through the autumn, rain—wise, there is a concern that there will be some further flooding because we could see another half a month's worth of rain in some parts of england, wales and later up into scotland as well. it looks pretty wet for northern ireland as well. all this rain is meandering around an area of low pressure sat towards the south—west. so, even once the main rain clears, there'll be showers around, some quite hefty ones. may dry up for a time, but we'll have a legacy of drizzly and rather cloudy weather, low clouds and some hill fog around as well. you can see the day looks quite wet through the midlands, northern england and through the afternoon as well. that rain's creeping up into eastern parts of scotland. so, the north—west, after a chilly start, might see the best of the sunshine.

the northern isles as well doing quite well in terms of dry and bright weather on saturday, but the rain then arrives through the evening and overnight, across eastern and north—western parts of scotland. elsewhere, well, we see a brief ridge of high pressure, so that's a window of drier weather, 12 to 24 hours for most of us before the next low pressure rolls in by the end of sunday and into monday. so, sunday does look like the drier day of the weekend for most of us — not all of us, but most of us. however, there'll be a lot of grey weather, some morning fog. of course, after all that moisture around, that takes a long time to clear in november because we're lacking strength in the sun, and then it just lifts into low cloud. we've got a much wetter day for the northern isles and here comes the rain later on. the winds won't be as strong tomorrow as they will be today, so it'll feel cold today just because of the wind as well as all the cloud. but that's easing tomorrow. but still, it's only 9s to 11s, which is about average for the time of year. sunday night sees the arrival

of the next band of rain — turns quite showery. tuesday's rain, or monday night and tuesday's rain, looks a little bit more persistent once again, so we're into this unsettled picture. temperatures are up on those of last week. there's just a hint that later in the week we might again get a respite from the rain and have some drier weather. bit for the weekend, rain is definitely the concern. particularly, as we say, in england and wales and then into parts of scotland. it does look drier for many of us on sunday. the warnings are on the website.
