of living crisis deepens. zoe o'brien, bbc news. now it's time for a look at the weather with ben rich. hello. there will be places that stay dry through the rest of today with some lengthy spells of sunshine. but in other spots, some blustery winds and some quite heavy thundery downpours, particularly along the line of a weather front. this narrow band of rain pushing out of southern scotland and northern ireland into the far north of england could be the odd flash of lightning, the odd rumble of thunder, some heavy thundery showers into northwest scotland. quite windy out there for many. highest temperatures across eastern england, up to 25, maybe 26 degrees. through this evening and tonight, this band of rain will sink its way south tending to break apart, but still the potential for the odd sharp shower in north wales, the north midlands. by the end of the night, more showers into north west scotland, dry elsewhere with lows between ten and 15 degrees. now, tomorrow across

northern ireland, scotland, the far north of england, it should stay mostly sunny with just the odd shower. further south we'll see more cloud rolling in from the west, providing rain for parts of wales and the southwest by the end of the day. highest temperatures in the east of england, 25 degrees. hello. this is bbc news. i'm lewis vaughanjones and these are the headlines. sevastapol, the home of russia's black sea fleet in crimea, appears to have come under drone attack again. mexico's former attorney—general is arrested in connection with the disapppearance of 43 students eight years ago. human rights campaigners call for the immediate release of a saudi student jailed for 3h years over critical tweets. the widow of the basketball legend kobe bryant tells a court of her devastation by leaked photos of a crash that killed her husband and daughter and six others.

more travel disruption on train lines across the uk as thousands of rail workers go on strike for the second time in three days over pay and working conditions. despite a year—long family feud, the coronation of a new king of the zulu nation is taking place in south africa — the first such event in 50 years. now on bbc news, click is all about sustainable travel. this week, more green, clean fun in the sun.

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 1950s, 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 one 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, it is slightly depressing that even with a highly efficient body it's those solar panels that need to get more efficient if we are to run completely on solar in future. maybe for now we need _ completely on solar in future. maybe for now we need to _ completely on solar in future. maybe for now we need to focus _ completely on solar in future. maybe for now we need to focus on - completely on solar in future. maybe for now we need to focus on getting l for now we need to focus on getting more power into batteries quicker. can i show you something that might help? he was a british company

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 would take about three ours, 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 in just 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 cards. it can move forwards and backwards, from side to side and you have three detachable batteries. they only take three minutes to charge and are also a seed sockets and thanks to 2000 cells inside it

can provide 30 kilowatts of power, about the same as a tell lap power wall. there are still issues to be overcome. what happens to the battery at the end of its life? find battery at the end of its life? and there are compromises. if you don't imagine _ there are compromises. if you don't imagine ah — there are compromises. if you don't imagine an additional ten or 20% lower— imagine an additional ten or 20% lower run— imagine an additional ten or 20% lower run time but can get all that energy— lower run time but can get all that energy in— lower run time but can get all that energy in five minutes, this is something our technology allows. once _ something our technology allows. once tab — something our technology allows. once lab trials are finished it will be time for industrial testing and validation in i hope these fast charging batteries could be speeding up charging batteries could be speeding up our lives in the next few years. hello and welcome to the week intact. nintendo announced the brat 0f intact. nintendo announced the brat of the wild sequel is delayed until 2023, elon musk is thinking of building a new social media platform thatis building a new social media platform that is open source and supports cryptocurrencies and tiktok

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. it 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. a p pa re ntly 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 belt 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. on 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 nauticalfunctions. 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 notjust 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. ~ ., ., the future. with world trade growing. — the future. with world trade growing. it's _ the future. with world trade growing, it's important - the future. with world trade growing, it's important we | the future. with world trade | growing, it's important we do something to reduce co2 emissions by “p something to reduce co2 emissions by up to 40% in 2030. we are using wind. this is where you get the different, the most power, that is where you have an aeroplane rink that can be put up the ship. measuring the flow that is clear is really— measuring the flow that is clear is

optimise routing, how you can optimise wind sales and combining that will bring us up to 90% co2 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 —assisted for you take 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 it's also a very environmentally friendly way, that would make it super interesting for all ship owners in the world.- super interesting for all ship owners in the world. that was nicola s le owners in the world. that was nicola style finishing _ owners in the world. that was nicola style finishing off— owners in the world. that was nicola style finishing off the _ owners in the world. that was nicola style finishing off the sustainable - style finishing off the sustainable journey by road and water on what turns out to be let's 22nd birthday. 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.

hello. we've got some rather blustery weather out there in some parts of the uk today, some quite brisk winds for the time of year, bringing some heavy and perhaps thundery downpours, but there will be many places that stay dry with some spells of sunshine. what we have is an area of low pressure to the north—west of the uk, quite a few white lines, quite a few isobars indicating those brisk winds, and a weather front journeying southwards with a narrow band of heavy and perhaps thundery rain. those are the sorts of wind gusts around lunchtime, 40 mph gusts still possible across parts of scotland, especially up to the north—west. this band of rain working its way southwards out of northern ireland and scotland, getting into the far north of england through the afternoon with the odd heavy thundery bursts. some blustery, perhaps thundery, showers to the north—west of scotland. ahead of our rain band, mainly dry, just one or two showers and spells of sunshine, and the highest temperatures across eastern england up to 25 or 26 degrees. now, during this evening and tonight, our band of rain will sink its way southwards, tending to fizzle as it goes,

there could still be the odd sharp shower into north wales, the north midlands by the end of the night. further showers pushing into the north—west of scotland. most other areas dry with clear spells and temperatures between ten and 15 degrees for the most part. now, tomorrow, some differences, compared with today. across the north, it will be sunnier than it has been today. across the south, cloudier, thanks to a weather system beginning to push its way in from the atlantic. this weather system will take a while to arrive so most of us on sunday morning will get off to a fine start with spells of sunshine, a few showers here and there. northern ireland, for scotland, for the far north of england, it should stay mostly sunny, albeit with the odd shower, but further south, we will see this cloud rolling in from the west, providing some splashes of rain quite sporadically during the afternoon, especially for parts of wales and the south—west. 25 degrees there in norwich, more like 18 the high in glasgow. now, as we go through sunday night and into monday, this weather

system will make its move, delivering some heavy thundery bursts of rain in places, so it could be quite a soggy start to the new week for some. some outbreaks of rain in places on monday. the rest of the week looks predominantly dry, a few showers here and there, and turning quite warm for a time in the south.

good afternoon. train passengers are facing a further day of disruption after thousands of rail workers started another 24 hour walk out in a dispute over pay and conditions. across the country, only around 20% of services are running. the government say the strikes could be ended if the unions put the pay deals on offer to their members. this report from our correspondent, helena wilkinson.
