university, playing an important part in the future of autonomous, sustainable and connected transport. and in a city where the first ever british car was manufactured, research has moved to the next evolution of the automobile, the autonomous vehicle. for a few years now, we've been told that driverless cars are just around the corner. and on this programme, we've taken a few for a spin. but before they can truly become a reality, we need to know that we can trust them just as much, if not more, than a human driver. and if this driverless world comes about, it will be transformative. not just for the drivers but also for the cities. so we may need to rethink some of the basics. we are used to a lot of congestion on our roads but it seems here like this model of

autonomous vehicles seems to actually overcome some of that congestion. 50 actually overcome some of that congestion-— congestion. so we know that --eole congestion. so we know that peeple spend _ congestion. so we know that peeple spend a _ congestion. so we know that people spend a lot _ congestion. so we know that people spend a lot of- congestion. so we know that people spend a lot of time . people spend a lot of time driving around that is creating congestion looking for parking space. with fully autonomous parking you need fewer spaces that will reduce the requirement in infrastructure and in cities for the real estate needed for parking solutions. the vehicle will literally drive itself into a car park, find its spot, recognise the white lines and pull in and park itself. clearly the technology has come a long way but before our streets can be filled with autonomous vehicles, the companies need to figure out how to train them. and we as a society need to be confident with the rules and the choices that we allow them to make. this is what we were promised — i took a ride in this truly driverless carfrom i took a ride in this truly driverless car from russia around the streets of las vegas last year. it was both

terrifying and weirdly underwhelming. turns out the car was a much more sensible driver than most humans i know. it did me three attempts to pass my driving test, not my fault obviously, but perhaps i should have come here to cambridge where the tech firm five has developed a sort of driving school for driverless cars. five runs endless simulations to ensure that driverless car tech responds safely to challenges on the roads. 0ne safely to challenges on the roads. one small scenario has nearly 500,000 possible variations. like me, our virtual car does not pass every test first time in the simulation. any driver will tell you it's those unusual moments on the road that you were not expecting that pose the most danger. a kangaroo runs out in front of you. what? it has happened! it prompted —— prompted the firm to created first library of edge cases. we are creating the first true

driving test for autonomous vehicles on the idea is when autonomous vehicles are arriving in the uk, how will the government know that they are safe for uk streets —— drisk? but getting the data to build the library has not been easy because people don't tend to report near misses.— to report near misses. we've had stories — to report near misses. we've had stories of— to report near misses. we've had stories of people - to report near misses. we've had stories of people driving | had stories of people driving around roundabouts and seeing somebody take the wrong turn and driving along a motorway up the wrong way and one individual described in mv divisional of having sheep appearfrom nowhere divisional of having sheep appear from nowhere as they were turning around the corner —— and one individual. this -- and one individual. this driverless _ -- and one individual. this driverless car— -- and one individual. this driverless car is _ -- and one individual. this driverless car is like - -- and one individual. this driverless car is like a - -- and one individual. this driverless car is like a bit l —— and one individual. this driverless car is like a bit of a hive mind, there is a fleet of them currently driving around london, clocking up hours and hours and hours of experience which they then all use in order to make them better drivers. london based wayve doesn't make its own cars but instead builds the brains for others. but instead builds the brains for ethere— but instead builds the brains for others. ~ �* ., ., ., for others. we're not going to net for others. we're not going to get there _ for others. we're not going to get there by _ for others. we're not going to get there by taking _ for others. we're not going to | get there by taking technology from one or two decades ago and trying to commercialise it with brute force and billions of dollars of capital. things like

future of autonomous vehicles not only relies on navigating difficult roads but also reacting to new situations. and now potentially passing a government driving test. and i don't know many humans who pass their test first time. they were you there. now when it comes to the future of transport, sustainability is key —— zoe there. and that's notjust key —— zoe there. and that's not just on the key —— zoe there. and that's notjust on the ground. up in the skies, the race is on to decarbonise aviation. companies are looking at different ways to be able to make air travel more environmentally friendly. and much is like has been looking at some of the more dramatic solutions. —— marc cieslak. here is the problem. the environment. we as a species are negatively impacting it in lots of different ways. aviation

contributes to just over 2% of global emissions stop pre—pandemic, the number was predicted to rise fast. the problem with aeroplanes are those. and the fuel that they run on pollutes the environment when it is made and when it is used so engineers, scientists and aerospace companies are looking at ways of cleaning up the stuff that comes out of those. if the stuff that comes out of those. ., ., ., ., ., those. if we are going to allow --eole those. if we are going to allow peeple to _ those. if we are going to allow peeple to keep _ those. if we are going to allow people to keep on _ those. if we are going to allow people to keep on travelling . people to keep on travelling then we're going to have to make aircraft which are far more efficient. so there will be a real pressure to develop technologies, new shapes of aircraft, new propulsion systems that fundamentally reduce the fuel burn of aircraft. reduce the fuel burn of aircraft-— aircraft. here at the university _ aircraft. here at the university of- aircraft. here at the - university of cambridge's whittle laboratory, they

specialise in work related to turbomachinery. there are several technologies being developed but i considering sustainability and new methods of powering aircraft. —— but are. there are a wide variety of different projects under way encompassing different kinds of aircraft and new engines and components for big commercial airliners to projects like this one, testing out the efficiency of distributing lots of other deeply powered propellers across an aircraft's wing. fine across an aircraft's wing. one ofthe across an aircraft's wing. one of the advantages _ across an aircraft's wing. one of the advantages of - across an aircraft's wing. que: of the advantages of electric propulsion is that rather having one or two large jet engines, you could have many smaller electric motors powering the aircraft and they have a very similar efficiency, whether they are very small or very large, so you might see aircraft with maybe a dozen propellers in front of them and it allows them to design smaller wings and more efficient wings. smaller wings and more efficient wins. ., , ~ efficient wings. solutions like this have the _ efficient wings. solutions like this have the potential- efficient wings. solutions like this have the potential for. this have the potential for smaller, lower range aircraft, but for bigger aeroplanes with longer range of the look and design of the outside and inside of these airliners that

we're all with change. leading us to the designs like this one, the blended wing. concepts like this offer big advantages in terms of saving fuel to the aircraft's shape, generating large amounts of lift. they also reduce noise as a result of the engines being mounted above the wing. and more recently the blended wing concepts were exploring hydrogen as a fuel source that produces zero harmful emissions. but these radical designs, like the blended wing, come with their own issues. the technology _ come with their own issues. the technology is — come with their own issues. tue: technology is very come with their own issues. tte: technology is very important but it's getting the infrastructure to go with the technology which would radically change on the airport level as well. it would change the fuel that implies an entire infrastructure to bring the fuel into the airport as well. they will also do away with windows for passengers. the

wing blending into the cabin means you just can't have them. instead, there's a that passengers will have virtual screens which should make up for the lack of a real view. well, that's where hybrid technologies come in. aircraft which look like a conventional airliner gas engines on the wings but with an additional fan behind the tail. this is a concept known as boundary layer it ingestion. concept known as boundary layer it ihgestioh-_ it ingestion. boundary layer ingestion — it ingestion. boundary layer ingestion is _ it ingestion. boundary layer ingestion is a _ it ingestion. boundary layer ingestion is a technology i it ingestion. boundary layer i ingestion is a technology which is aimed at taking the flow that forms over the surface of an aircraft, the flow that is on the surface it is what is usually form the wake of an aircraft and causes the drag. the idea we have is to have a fan that is wrapped around the back of the fuselage so it can just all of this parasitic flow, at the back of the aircraft, and takes it in and re—energise it and turns it

into useful thrust. re-energise it and turns it into useful thrust.- re-energise it and turns it into useful thrust. time is the enemy here — into useful thrust. time is the enemy here though. - into useful thrust. time is the l enemy here though. aerospace into useful thrust. time is the - enemy here though. aerospace is traditionally a very conservative industry. can a significant amount of research and development occur in time to address the world's urgent climate issues? 50 to address the world's urgent climate issues?— climate issues? so if we're coin: climate issues? so if we're going to — climate issues? so if we're going to decarbonise - climate issues? so if we're i going to decarbonise aviation by 2050 then we need to get down to 1980s levels of emissions by 2030. so if you're looking at radically new concepts, you need to be able to work in a hardware— rich environment, you need to be able to build and test a lot of things because many of those ideas are going to fail.- ideas are going to fail. here in bedfordshire, _ ideas are going to fail. here in bedfordshire, bluebearl in bedfordshire, bluebear systems specialise in building uavs for commercial and military use. they are leading a consortium including engineers from cambridge in designing a propulsion system for a small zero emissions

easier to get into. the full—size pot is expected to fit around 25 people, but more importantly than that, it's going to house all of the tech that makes this hyperloop system work. that is important because if something breaks or goes wrong, all they have to do is remove the pod and fix it somewhere else, instead of going into the tube and potentially disrupting a lot of travel. 0ne potentially disrupting a lot of travel. one of the key components of hyperloop travel is the ability to go really, really fast. so they designed away for the pubs to levitate using opposing magnets which in theory will help it go as fast as an aeroplane. the pods will travel in tubes about this size, and should be able to reach speeds of up to 670 mph. that is fast enough to get you from london to paris in under half—an—hour. the system of tubes can be built on land, overwater or underground, and maybe, just maybe one day, across oceans. by building an

entirely new infrastructure across a city or country will take a lot of work, and a lot of money. but virgin's hyperloop system isn't the only one being developed. underneath the streets of las vegas is another hyperloop tunnel, this one by the boring company, yes, the one owned by elon musk. his system will essentially be a underground motorway. 0ld system will essentially be a underground motorway. old tv shows and movies may have led us to believe the future of transportation will include flying cars, but may be the modern day version of that is actually a pod flying through a tube. that was cody. electric vehicles are becoming commonplace on many roads. but the problem is, you've got to charge them, and it is not always as simple as we would like it to be. so how about putting down the lead and opting for a spot of wireless charging, courtesy of the road? just think of it as being like putting your mobile phone on a wireless charger. the aim of

this taxi isn't to be fully recharged, butjust to get this taxi isn't to be fully recharged, but just to get a bit of a boost while it is waiting at a taxi rank without any passengers. but maybe we are missing something here. why worry about recharging the batteries, when we could just be swapping them? stephen beckett has been to taiwan to look at some other ways electric vehicles could be powered. this is type a's famous but perhaps infamous scooter waterfall. famous but perhaps infamous scooterwaterfall. it famous but perhaps infamous scooter waterfall. it is one of the main routes into central taipei for thousands of commuters every way. it is mind—boggling how many mopeds there are here. thousands of them, theyjust keep on coming. and you really get a sense of just how much pollution these guys are probably causing. this is the same spot a few weeks later, believe it or not a good chunk of those bikes aren't producing any pollution at all. this is publicity stunt for

ever you can keep up with the team on social media, find us on youtube, instagram, facebook and twitter. thanks for watching and we will be back next week. hello there. the hottest weather of the year so far awaits us as we head into the weekend. it's sunday that will be the hottest day of the two, with temperatures reaching 30 degrees in the very hottest areas. it's pretty humid across parts of england and wales on friday, but that humidity will be easing somewhat as we head into the first part of saturday morning. fresher air moving in for most. that said, it will stay pretty humid around the channel islands, still with some low cloud and some fog patches here to start saturday morning. 0therwise, we've got

broken cloud, and these are the kind of temperatures we'll have to start the day — around about 10—14 degrees for most, so a mild start to the day already. now, for saturday morning, really, across the northern half of the uk, you'll see patches of cloud. eastern scotland probably having some decent sunshine. wales, the midlands, east anglia, southern england as well having a largely fine and settled start to the day with plenty of sunshine, too. for most areas, the weather will brighten up, but it will turn cloudier and more humid in northern ireland and western scotland. it never gets that warm, for example, in stornoway — 1a degrees here. further southwards, that's where the highest temperatures will be. across england and wales, low to mid 20s once again. and for the cricket of edgbaston, unlike the first test, no chance of interruptions. this time around, it stays dry with lots of sunshine. and wales get their european football campaign under way in azerbaijan. it will stay dry with warm sunshine here. now, for the second half of the weekend, the weather's going to get even hotter. high pressure building in for most of the uk, although we do have this pesky weather front moving into the far northwest, and ultimately, that will bring

some rain across the far northwest of scotland. but otherwise, most parts of the country having some long spells of sunshine, and for many, it will be very, very warm and feeling really quite humid. 26 degrees in aberdeen. highs reaching 30 degrees in the hottest areas further south. never that warm across the far north—west with that thicker cloud and the rain. it does mean as england start their european campaign against croatia at wembley, it's still going to be pretty warm — 27 celsius — and a warm night will follow sunday night. these are the temperatures, still, at 11 o'clock. a warm one for sleeping with those temperatures still well into the 20s. into next week, there will be some rain moving in to some northern areas of the uk, but it'll be still sunny and very warm further south.
