hello, this is bbc news. i'm shaun ley. the headlines. the unite union has announced eight days of strike action by staff at the uk's largest container port, felixstowe, in a dispute over pay. the met police say they had contact with owami davies on the day she was reported missing by her family. daria dugina, the daughter of one of president putin's close allies, dies after her car exploded as she was driving home. now on bbc news, click is all about sustainable travel. we are in the netherlands to look at a solar—powered car and in sweden to hop aboard an amazing electric boat. this week, more clean, green fun in the sun with battery robots, solar cars and electric boats.

in an unassuming garage in the netherlands, there's an electric car with a secret. no, it's not its ultra—light, ultra—strong carbon—fibre frame, although that is important to the story, and it's not the aerodynamic design that makes it look like a future car from the 19505, although that is important too. no. look closer at that shiny finish, and you'll see that it's not paint. the entire thing is covered in solar panels — solar panels on the bonnet, solar panels on the roof, solar panels instead of a back window. yes, this is a solar—powered car, and they call it lightyear one.

the first production model will be going on sale this summer. its five square metres of solar panels come in narrow sections that better curve around the body and also mean that if it's parked partly in the shade, the sections that are in the sun still work at full capacity. but even though the battery can take you 440 miles on a single charge, a day's worth of sunlight will only provide about 45 miles of that. the rest still has to come from plugging it in. however, 45 miles might be enough to get you to work and back. you can fast—charge it using a normal charger, but the solar panel will recharge your commute every day. so, basically, when you put it outside of your office space, then it recharges itself, and when you get back, the car is full again.

and, basically, that happens every day. in the summer in the netherlands, you wouldn't have to charge for months if you do just your commute. really! i'm from the uk — i know what you're talking about, yeah. yeah. and, basically, uk and the netherlands are the worst i%, right? it will get a lot better when you go to south europe. why did you set up a company here, then, and not in the sahara? because we love the sun because we see it so less. actually, the netherlands is a european leader in solar power, getting as much as i7% of its energy from the sun. lexis a bit of a world leader too. in 2012, he co—founded the team that went on to win the solar challenge cruiser race across the australian outback four times in a row. unsurprisingly, the design of lightyear one is somewhat more conventional. now, solar cells are getting better and better at turning sunlight into electricity, but lex's company is more focused on making what energy it can harvest go further.

the result will be the most energy—efficient five—seater on the market when it launches, with a ruthlessly aerodynamic design weighing about half a tesla model s, and which trades the crazy acceleration of that beast for range and efficiency. so, the tendency has been for electric cars to look at high acceleration and large batteries. so, because of those two, cars get very heavy, and very heavy cars that accelerate quickly, they need very high power. so, we say it's more important to get to the destination quick than it is to be quick at a traffic light. and what's great about in—wheel motors is that they are direct drive, so, basically, there's no gears at all. there's just four moving parts — four motors. that's it. so, it means that no heat is lost in drive shafts or other gears, etc. so, every bit of energy goes directly to the motors and to the wheels. and that makes it more efficient and therefore on the same amount of solar you get in, you can drive more.

now, lightyear 0ne isn't the only solar—powered car being developed. this one from german outfit sono is due to hit the market in 2023. and, look, of course it makes sense to get your electricity free of charge from the sun rather than from fossil—fuelled power stations. but solar cars also come with new challenges. for a start, you're going to need to keep it clean to maximise charging. and you know those stone chips you get in your windscreen? well, now, much more of the car is covered in glass, although lightyear does say that any chips can be filled with resin in the same way as windscreens. it does seem like it's been a long time coming, but looking at this, it is a bit easier to believe that one day your car might be wearing a sea of solar cells. but you know, lara, it is slightly depressing that even with a highly efficient body, it's those solar panels that need to get more efficient if we're to run completely on solar in future.

maybe for now we need to focus on getting more power into batteries quicker. that's a nice idea but it is hard. can i show you something that might help? here's a british company hoping it has sold the fast—charging challenge. the nyobolt cell is the same size and weight as a traditional lithium ion one but it can power things better while it's doing the job and crucially it charges a lot faster. the eventual aim is three minutes compared to three hours, and here in this lab, batteries are being tested along with visualisations of their charging speed, heating and the current. the cells are then grouped together and tested in regular devices. it's possible to charge batteries in five minutes. we have had robotic vacuum cleaners charge in three minutes. it's possible to charge power tools in ten minutes or less. much of the success here lies

in the development of a new material which allows lithium ions to transfer quickly at a safe temperature. the heating you get primarily. because your anode and cathode materials are not able to move . lithium ions fast enough and then the heating causes a whole series of degradation, - electrolyte decomposes, _ the cathode decomposes, giving off oxygen and that causes fires. but even having addressed this, there are still challenges for the fast charging of the thing many of us care about the most, our smartphones. years of miniaturising their subsequent growing screen sizes has made this more difficult. these limitations come from the components, so the wires and connectors, and are usually limited to five amps, that is what you have in most usb sockets so the usb—c has to go to its next generation. that can allow faster charging

and you need chargers that wouldn't become too big and bulky to carry around. vehicle charging is on the agenda as well. when it comes to recharging electric vehicles, there are a lot of variables. this isn't exactly your standard electric car. to fully power something like this right now would take about three hours, partly because the initial bit of that charging happens quite fast and then it slows down later, but these batteries should overcome that problem, making it possible to reach full charge injust five or six minutes. driverless taxi pods could spend more time shuttling people rather than sitting charging. the company has also been working on this prototype mobile charging device. the idea is it can be used on building sites or to charge cars. it can move forwards and backwards, from side to side and you have three detachable batteries.

they only take three minutes to charge and there are also ac sockets, and thanks to 2000 cells inside it can provide 30 kilowatts of power, about the same as a tesla power wall. there are still issues to be overcome. what happens to the battery at the end of its life? and there are compromises. if you don't mind an additional 10% or 20% lower run time but can get all that energy in five minutes, this is something our technology allows. 0nce lab trials are finished it will be time for industrial testing and validation in the hope these fast charging batteries could be speeding up our lives in the next few years. hello and welcome to the week in tech, in the week nintendo announced the breath of the wild sequel is delayed until 2023,

elon musk says he's thinking of building a new social media platform that is open source and supports cryptocurrencies, and tiktok announced a new in—app creation tool called library with select content from giphy, the source of many gifs and animated stickers, it aims to encourage more entertainers to access content and take part in trends. the pompeii archaeological site is using a spot robot dog to explore the ancient ruins, collect data and assess structural issues. authorities are also using laser scanning grounds to help create 3d models of the site. as part of its move towards zero, the government in britain has ordered research to begin on orbital solar farms. proponents of solar power in this form believe they can provide round—the—clock renewable energy that's wirelessly beamed to earth and fed into the grid, and finally dyson have announced the launch of their new noise—cancelling headphones that come with a built—in air purifier.

the company claim the cans can deliver a continuous stream of clean air without touching the wearer's face. you heard it ear first. this is greenwich naval college in london. with its brand—new cycle way, play area, benches and bike park. it's an urban regeneration that didn't need council approval — in fact it was only completed ten minutes ago. it's a visualisation of how things could be, the kind of thing you see skilled urban designers make, although this is betastreets, a tool that can be used by anyone. often the visualisation can be done at the end of hundreds of thousands of pounds of design work and then the decision—makers decide they don't like it, and therein lies a problem because a lot of money and time has been spent getting there.

we kept betastreets as a simple tool for most people and not something you need to work in design for two years to be able to do. the idea is anyone can take a photo of their local area, upload it to betastreets and the software will do the work for you. this tool analyses the photo to work out the geometry of the image and that makes adding street furniture, cycle lanes and trees a doddle. is that a sensible place to put a bike hangar? laughter. that's a no, then. this is chaos. you do not want someone like me having a go at your street. let's put a slide here over the kerb so you can climb up there and then slide down onto the red bit of the road. have you got flumes? that's something we could add in. i can see the shadows of the tree tracing across the bench. 3d gaming engines like unity

and unreal engine take care of the visuals, allowing objects and lighting to be easily manipulated and opening up a previously highly skilled profession to many more people. they have been around a while but it's more that people's computers can now handle what we are giving it. i mean, this is fun. it's a disaster for me and for everyone that lives on that street but it's fun so i can how people would engage with this. it's incredibly easy, that's the first time you have used it and ok, you have made a bit of a mess but it looks. . .semi—believable. whether or not you would put those objects there... it looks... longest pause in the history of television. ..believable! the system was used by the charity london cycling campaign to start a conversation about making london's streets greener and more cycle—friendly.

not sure i'd want to have a conversation with the residents of this street. think i will leave it to the professionals. because this tool runs in a browser it's fairly easy to make it run on a tablet or phone, which means you can take the photo you need and then stand on the street corner and do your sketch there and then. different cities will require different solutions in their quest to become sustainable so let's go somewhere completely different. i'm going to hand you over to captain lewington. it's icy out there. it's very, very icy. with 3,000 kilometres of coastline and nearly 300,000 islands, sweden plays host to a variety of sailing vessels. motor boats use fuel that create greenhouse gases. they can leak petrol and they can

cause noise pollution. so, i'm here to take a look at some electric boats that aim to overcome these problems, including one that doesn't cut through the waves, but glides above them. right, i'm following you. yes, come. under this 25—foot craft is a wing for hydroplaning and sensors that collect hundreds of data points every second. you'll have to take the passenger seat first. 0k. and then we'll let you drive. we need to stabilise it, much like a fighterjet. then we feel how we're oriented, where we are in the world, and then about 100 times per second, we are adjustable by twisting it and changing the angle to keep stable. this is where it gets exciting. let's go.

wow! i can feel the sensation of the boat lifting up. it does actually feel like we're flying. and without the hull in the water, it's using 80% less power than a boat would conventionally need. batteries are still no way close to the same energy density as gasoline. but as hydroplaning reduces friction, electric becomes a more viable energy choice. this feels beautiful. whilst most electric boats eat up more energy the faster they go, this consumes the same at five knots that it does at 20. on a full charge, it can hydroplane for two hours, covering 50 nautical miles at a sensible 20—knot cruising speed. and we can have a conversation like this. it's not like it's slamming in the waves. which is very sociable, and it also feels very smooth, like an electric car. you want to try it?

i'd love to. ok, let's do it. apparently this is easy and when i raced a tas lacked a little while ago and beat a race driver that was easier than i was expecting so let's do this. seat belts on, everybody! i took to this like a duck to water. well, after a few big unplanned splashes. that feels faster than you went. pull it down a bit. i'm heading for the big waves. whoa — whoa! that was amazing! good work! i barely felt those. a very different experience to our producer's boat. thank you for the warning! it's a leader amongst its electric peers, but i do wonder if prices — starting from around $300,000 — might stall adoption, especially when similar—sized motorboats can still travel several

times further and go around ten knots faster. of course, there's going to be petrol—powered boats for quite some time, but, i mean, once you try this kind of experience, it's quite easy to imagine everyone driving like this. yeah. and when you're here, looking at this beautiful water and the beautiful scenery, it feels good to know that you're not damaging the environment whilst you're out. 0n land, bigger crafts are under way, with a 40—foot public shuttle set to launch with the city of stockholm next year. this is our first electric hydrofoiling ferry. this one will be able to carry 30 passengers. and it's exactly the same technology, just scaled up? exactly. it's the same concept. but next for me is another swedish company called x shore that's making electric boats better connected. hey!

hello. nice boat. thank you, thank you. she's a beauty. i believe you have something to give me before we get on board. i have. so, you will be able to start the boat with this one. garmin�*s gps and vitals—tracking smartwatch comes with added nautical functions. man overboard on, unlocked. and then if you fall in, then it stops. now, this won't be as energy—efficient as hydroplaning, but it's still powerful. in four seconds, we will be up well above 30 knots, so everyone needs to hold on. is everyone ready? yes. give her everything you got. just full throttle. laughter. yep, i'm flooring it. it's similar to candela in cost and top speeds, but can cruise slowly for double the time. as it sails, the vessel collects 150 data points each second. everything is shared back to h0 to optimise performance, but with private info being beamed

straight from my wrist, i was curious about security. technically, you can hack the pentagon, right? so, you can probably hack our boat, if you're that good, but we have the same kind of security layer as any car company. just like connected cars share data to improve urban spaces, smart boats could help local authorities improve life at sea. so, this is our r&d lab. so, this information like water quality and water temperature... mm—hm. ..you can't do anything about it. no. so, how much use is that data? for the cities, it's lots of use because they can see if the temperature suddenly rises, where to go swim, where to avoid, if you have coral reef areas. i mean, this is something that our customers would want to monitor, actually.

with remote—control tools built in, floating sea labs could one day operate themselves. are you working towards these becoming autonomous? yes, we are. when? in a few years' time. a few years. that was great fun but it's not just about that. 90% of the world's trade is shipped and that accounts for 3% of all co2 emissions. going electric could be one solution but another is using sailboats, and one company has been trying to bring that idea into the future. with world trade growing, it's important we do something to reduce co2 emissions by up to 40% by 2030. we are using wind. this is where you get the different runs, where you have the most power, that is where you have an aeroplane

wing that can be put up the ship. measuring the flow that is actually clear is really difficult. this vessel here is seven metres long, mainly made out of glass fibre. the full—scale ship will be around 200 metres long, roughly 80 metres in height and the mission is this would sail at the end of 2025 or early 2026. what makes wind really interesting, it's of course free of charge, we know there will be wind in the future. up there, you will have very little disturbance. it has been a lot of learnings. we have roughly around 150 sensors measuring up to 200 data points every ten seconds, pressure, wind speed and also the direction of the ship. when you change the angle of attack, that will be a big difference in how

you can optimise the hull, how you can optimise routing, how you can optimise wind sails and combining that will bring us up to 90% c02 reduction. there are unexpected things going on. one example, when the wings are flipping over there and it also starts to move backwards, so these are things we have learned and then look into how we can work on that to make sure you avoid this going forward. when it comes to the full systems over the atlantic ocean you will have very good solid wind more or less all the time. if you get closer to the equator you will have less wind where you need to put in some other kind of energy. it could be a wind assist for you just to reduce co2 emissions from the main engine. you also need a back—up system in case you have no wind. taking new steps will be a challenge.

the shipping industry has been going on for the last 100 years. what we can show as if this is a profitable way of going forward and also a very environmentally friendly way, that would make it super interesting for all ship owners in the world. that was nicholas zull finishing off the sustainable journey by road and water on what turns out to be click�*s 22nd birthday, would you believe? now, we're making a few changes behind the scenes here on the programme, so while we get things sorted, we're going to treat you over the next few weeks to a few of our favourite programmes from the last few months. do enjoy those. we'll still be on social media. on youtube, facebook, instagram and twitter at @bbcclick. thanks for watching, and we'll be back soon.

hello. let's take a look at the weather for the week ahead. in general it's going to be quite a messy picture as we head into next week, rather unsettled, low pressure dominating and a bit of everything in the forecast, so some outbreaks of rain, most light and patchy but the odd heavy downpour here and there but also sunshine and towards there but also sunshine and towards the south in particular it will feel warm and humid that humidity is swept away by the end of the working week. here is the satellite picture from earlier and you can see with the cloud has been across england and wales and here we will see some clear spells overnight, the best across north—eastern scotland and north—east england on the weather front continues northwards and eastwards introducing a lot of

cloud, outbreaks of patchy rain and coastal and hill fog with the humidity levels rising towards the south. quite mild and muggy underneath all of the cloud and temperatures where we see the clear skies will drop back into high single figures. 0n skies will drop back into high single figures. on monday, this is where the weather front will be moving its way eastwards throughout the day, introducing mostly lighten patchy rain but there will be the odd heavy downpour as we head through the afternoon across the midlands and east anglia perhaps towards the scottish borders and some breaks in the cloud forming across northern ireland, western wales and the south—west of england through the afternoon but if you see any sunshine, watch out for thundery downpours as well. sunny skies for north—east scotland, temperatures 17 to 19 degrees elsewhere generally the low 20s but may be 25 celsius still in norwich. 0n the low 20s but may be 25 celsius still in norwich. on tuesday, most of us will be between weather systems but an occlusion the far west of scotland so shari outbreaks of rain pushing east and also lots

of rain pushing east and also lots of low cloud out towards the west and pantry outbreaks of rain but toward central and southern england, dry and sunny spells, and temperatures could rise as high as 27 and a warm muggy feel. this is the position of the rain on wednesday and the weather front pushes south and east and towards the north and west we always have fresh feeling conditions but the warmer feeling air sticks with us in southern and eastern areas of the uk and the weather front is also out and the weather front is also out and temperatures to get a size 28 or 29 celsius in parts of east anglia. the weather front, although 29 celsius in parts of east anglia. the weatherfront, although it 29 celsius in parts of east anglia. the weather front, although it is fizzling out, it could pep up as we head through thursday, especially on thursday night bringing much—needed heavy, thundery downpours maybe to east anglia and the south—east of england, so there could be some high rainfall totals on thursday night that eventually clears into the north sea leaving us some fresh feeling airjust north sea leaving us some fresh feeling air just about north sea leaving us some fresh feeling airjust about everywhere as you can see from the charts across

the capital cities, so friday, mostly dry, shari outbreaks of rain across northern areas of scotland and that's because we have low pressure centred there, and further south as we head through saturday, although it's mostly frontal rain moving into the far south, perhaps pushing north but still lots of uncertainty. i pressure is out towards the west and it is this that is going to drag down more of a northerly wind as we head into next weekend. of course, the bank holiday for some, so in generalfor next weekend, looking mostly dry, some showers towards the north of scotland, may be some rain towards the south but it will be patchy and feeling cooler.

this is bbc news. i'm shaun ley. the headlines at 5pm: the unite union begins eight days of strike action by staff at the uk's largest container port, felixstowe, in a dispute over pay. the met police say they had contact with student nurse 0wami davies on the day she was reported missing by herfamily. daria dugina, the daughter of one of president putin's close allies, dies after her car exploded as she was driving home. we'll be live in altrincham, where police will be making a statement shortly on the stabbing of tyson fury�*s cousin, rico burton. good afternoon. i am a detective

superintendent with greater manchester police. at around 3am
