of the water, too — it doesn't bounce about on the waves! it is pretty steady. i can't really tell i am out of the water, but i can tell i can feel the of something around. but actually, our boat is using the same hydrofoil but actually, our boat is using the same hydrofoi— but actually, our boat is using the same hydrofoiltechnologies, so it means is also _ same hydrofoiltechnologies, so it means is also out _ same hydrofoiltechnologies, so it means is also out of— same hydrofoiltechnologies, so it means is also out of the _ same hydrofoiltechnologies, so it means is also out of the water. i and look at him — he's having the time of life out there! this is the science bit. when you raise a boat almost entirely out of the water, it becomes unstable, because you have all the weight up here above the wings that it's balancing on in the water, a bit like trying to balance a pencil on yourfinger. in order to keep it upright, you have to do a lot of that, and that's what this boat is having to do. having to adjust its position hundreds of times a second

to keep it perfectly balanced. you couldn't do that manually, so this thing is covered in sensors that monitor exactly what the orientation is in the computers are doing the compensation and they do that by adjusting the angle of the wings in the water. again, hundreds of a second, to keep a perfectly balanced. why has nobody made an electric hydrofoil flying ferry before? i think the main reason is it's freaking hard! over 70 countries have commitments to net—zero targets. some are enshrined in law, others are golf laid out in policy. large companies have also

made net—zero pledges, but how do we know that they �*re being met? that they're being met? there's one company that might have the answer. satellites have been capturing images from space for decades. this is a radar one here. you've also got optcal images like these and any cloud cover around you won't see what is going on beneath and you need daylight for most of these. but satellite vu has a different plan, for them, it is about thermal imaging. its first satellite was launched injune on a spacex rocket flying out of california. it started sending back high—resolution images to earth, its thermal sensors enabling it to chase hot and cold features down to 3.5—metre accuracy.

that citcle, there's a lot more than four kilometres. it's the culmination of years of work. we have satellite view, the world's thermometer and these are literally the raw images. here, the first image we took was of rome, and you can see the hot areas in brighter colours and the blue areas are the cooler areas in the city. this one is taken at night, and what you can see, the vatican is very, very hot. this summer, there were big heatwaves, that building absorbed a lot of energy, and at night, it's radiating. the heat maps, which are still images in short images and videos, could have wide application, but a particularly useful in climate—related matters. we think every city would want this. there's a new city manager

called chief heat offices, seven appointed around the world, and one is in athens, for example. and they are wanting this data so they can go and help people help save energy. but the bigger picture is to help monitor how companies are meeting their net—zero commitments. you can look at oil storage, for example, and see how much fossilfuels are being burnt and how much are being pumped. when people are declaring net—zero or reducing their oil consumption, we can come and verify that that is actually occurring. 60 organisations are currently playing around with these early heat images to see if they can improve their existing climate models. we're striving to help the planet. you need this transparency of information. and we've done it.

in the race to reduce emissions, plans to build windfarms are sky windfarms are skyrocketing, but while the electricity they generate is clean, the green industry has a waste problem, and now the race is on to try and solve that, as adrian murray has been finding out. these towering machines are getting ever more powerful. nowhere is that more on show than at this test centre in northern denmark. it is the latest and biggest turbines they have, the prototypes. this is like seeing and tasting the future right here. the largest, a staggering 208 metres high, has broken world records for the most power. and experts say they're only getting bigger. this race towards bigger and bigger turbines will continue for a while more. we are looking into the possibility of creating a new test centre in denmark and the design turbine we are designing for is 50 metres from ground 50 metres from ground to highest tip. by 2030, wind power could supply

a fifth of the world's electricity, we need clean energy but this green industry has a growing headache when it comes to waste. turbines are built to withstand the forces of nature, the forces of nature — they're flexible, light and super strong. but that's also where the problem lies. when they reach the end of life, they're really hard to recycle. while the steel in the towers can be reused, the massive blades are almost indestructible. and as older models are replaced, many get dumped in landfill. by 2050, there could be 43 million tons of redundant blades globally that need to be dealt with. it is problematic because we want the renewable energy to be

truly sustainable, and if you have a waste material that goes to land filling, it's not truly sustainable. it's a problem players have been scrambling to figure out. now turbine makers siemens gamesa has had a breakthrough. it manufactures some of the world's biggest blades at its site here. and while this one looks like any other, it can be recycled. it all comes down to a resin called epoxy, which acts like a really strong superglue, binding together the fibreglass, binding together the fibreglass. usually, this is incredibly tough to break down, but not here. we change something in the backbone of the chemistry, this has gone through our recycling process, we just turn it around. you can see all the different glass hairs placed through in

the production of the blade and how they are separating from the blade. to do that, it needs to be soaked in a big bath of mild acetic acid. after a few hours at 80 celsius, you get the result you see here. so it's just like vinegar in a supermarket? exactly. exactly like you would make pickles or descale your coffee pot. i can actually smell that. there is a scent of vinegar coming from the blade. this won't tackle today's waste, but when these blades retire, the materials could go into making other things. we could be furniture, suitcases, you can use it for surfboard manufacture, etc. so general consumer goods. but not new turbines? not as it is right now, but i'm never going to say never. and that's it for our round up of some of the latest sustainability stories. hope you've enjoyed them. from sweden and me and my electric ferry,

thanks for watching. and... i wonder what this does? hello there. the weather so far this year has been making the news headlines for all the wrong reasons, with flooding, rain — it has been very unsettled. if we take a look at the satellite picture throughout this week, you can see areas of low pressure pushing their way from west to east, only to be replaced by another. and even once the significant lows have moved away, we've seen a rash of pretty frequent showers. but looking further ahead into next week, high pressure is going to build — we haven't seen this for quite some time. the isobars will open out, the winds will fall light. clear skies by day will lead to some frost and fog, but it will lead to a quieter story. and we'll start to see the first signs of that this weekend. largely dry. there'll be some cloud around,

but it will feel noticeably colder. now, as we go into saturday, we will have some lingering cloud to the east of the pennines from a weakening weather front, still quite windy up into the far north. and here still some showers into the northern isles. and here, still some showers into the northern isles. but there will be a slice of finer weather with a few isolated coastal showers and temperatures around 5—9 celsius. now, as we move out of saturday into sunday, this high pressure continues to build in from the west and it's going to merge with this one across into scandinavia. the winds will fall pretty light. early—morning mist and fog could be an issue, some of it slow to lift. and with that slight north—easterly across lincolnshire, down into east anglia and the south—east, could have a rogue shower through essex and kent. here, it'll feel a little cooler with any exposure to that breeze. and the temperatures a little bit below par for the time of year. clear skies by day will lead to clear skies overnight. frost and fog could be an issue, not just monday into tuesday morning, but throughout the week, particularly where the winds fall light.

so, monday morning, we will see a little more in the way of cloud around. we will be chasing cloud from time to time. that north—easterly breeze particularly bringing some cloud into east yorkshire, lincolnshire, east anglia and the south—east. and those temperatures perhaps at around 3—5 celsius. there will be some brighter spells the further west with a little more shelter from that breeze. the high pressure is going to drift its way steadily westwards. the winds still circulating around that high in a clockwise direction. so, with any exposure along that east coast, it could be a little bit fresher, but with the fresher breeze on tuesday, that should help to shift the cloud and there should be a little more sunshine coming through on tuesday. still not a particularly warm day, 3—5 celsius. certainly going to be a shock to the system as we haven't seen temperatures like this for quite some time. now, the high pressure not moving very far very fast, just drifting its way slowly north—westwards, the wind direction coming round to more of a north—easterly.

so, with that longer sea track, we'll see more cloud coming in off the north sea, so that means cloudier skies for eastern scotland, north—east england in particular, and perhaps hopefully a little more sunshine through central and southern areas. so, top temperatures, again, similar values through much of the week, but we're looking around 4—7 celsius the high. now, as we move further ahead, it looks likely that the high pressure is going to start to lose its grip and allow low pressure to move in from the north. and with that northerly wind starting to kick in, it may well turn colder still, darker blues, the temperatures falling away, and that could bring some showers as well, particularly into the north. and with those temperatures below par, well, some of those showers could be wintry in nature. but on the whole, a good deal of dry weather for the following week. enjoy.
