well, not too far away, another company is tapping into iceland's geothermal power to put us on an altogether different diet. this is food for us — or, at least, it will be one day. it's not something we're currently used to eating, mind you, but tastes change. it's algae. i know. sounds kind of ewww, doesn't it? but the microalgae growing in these test units are rich in protein and omega—3 — much more so than traditional crops grown in a field — and they also consume way fewer natural resources, too. in these systems, we can grow a tonne of protein and using 300, 400, 500 times less water and 1400—1500 times less land than the best thing that we know today. and in fact, because algae is a plant, it has another environmental benefit — photosynthesis. we get the c02 from the power plant, we get that into our system, we use algae to actually fix that co2 into biomass and they breathe out oxygen, so oxygen is actually our only by—product of this product. which is not a bad by—product, really. the health authorities don't seem to mind! spencer laughs. so, right here in geothermal iceland, where electricity and hot water are both essentially clean, green and on tap, growing this algae ends up being carbon negative — it pulls more c02 out of the environment than the electricity puts back in. but in order to feed the world, these algae farms would need to be placed around the globe, and not everywhere's on top of a volcano. the system itself is always carbon negative because we take in c02, we fix it in biomass and we breathe out oxygen. but if you're having to use electricity that's generated through coal... exactly. ..then the system is generating c02 as well... yes, yes. ..and can then you connect the pipe from the power station straight back into the algae and suck it back in? that — that is actually a possibility. this is what we're doing right now. these guys, they need c02, so we could actually take whatever c02 into the system, theoretically. and in fact, vaxa is thinking even further ahead than improving the environment here on earth. growing food in small spaces with limited water and producing oxygen as a by—product sounds like a pretty useful thing to be able to do, i don't know, in a moon base or on mars — if the colonists can stomach it, that is. all right, let me ask you a question — what does algae taste like? uh, basically the medium it's in. 0k. so this algae is a cold seawater algae. salty then? so it's salty. yeah. the problem is, this one is fairly robust. by "fairly robust", you mean a tough chew? it's a tough chew, yeah, it is. laughs. 0k, i've been made an offer that i can't refuse. kiti said, "would you like to drink some algae?" of course i would! oh, my life! for real, or...? 0k. i can do it first, if you want. you're not having a laugh? i can do it first. funky music plays. yeah, it's fishy. yeah. needs a little, um... what's it called? a lie—down afterwards — that's it. 0k. laughs. hmm, maybe it will take a more creative chef than me to be able to sell this straight onto the plate. —— nobody is going to eat algae paste, green goo, so that's not the idea. so we are going to use this prop to make food. because you get soy—based stuff. exactly. it's not like you extract the protein and make stuff out of the protein. i have solved your problem for you. you know how in posh restaurants, you have your main course and you have it in a red winejus, which is basically just gravy, so you need to call this al—jay and you can charge £100 a plate. i like it! hello. here's your tech news round up. it was the week that douyin, china's version of tiktok, announced it will limit the use of the platform for users under 111 to a0 minutes per day. the eu has proposed a common charger for mobile phones, tablets and headphones. imagine that! and streaming service netflix has bought the rights to all of roald dahl�*s books. and a week after apple showed off the new iphone 13 and watch series 7, it was microsoft's turn to tempt us with their shiny wares at their surface event. the company promised its most powerful surface pro device ever, the new surface pro 8, a new surface laptop and also hyped up a new iteration of its foldable phone called — wait for it — the surface duo 2. students from the netherlands have set off on a 3,000km road trip in what they claim is the world's first self—sustaining house on wheels. the concept, home, has an array on its roof that harvests energy to power the vehicle, making it fully self—sufficient. they are taking part in the european solar tour, which aims to raise awareness of the need for sustainable travel. and finally, nasa has chosen the site for its moon rover landing near the moon's south pole. the viper mission, slated for 2023, will attempt to find water ice on the western side of the mobile crater. the moon's south pole is actually one of the coldest parts of our solar system. i'm looking forward to seeing the dark side of the moon! is it a bird? is it a plane? it's a...bird—plane. i'm at a maritime innovation hub in reykjavik and i'm being taught how to command the silent flyer. flapping a bird drone. it's all right, innit? it's... it's kind of really relaxing, just watching it. oh, yeah. engineer peter, helped here by daughter clara, is the technical lead behind a very different and quiet kind of drone — one that emits less than 70 decibels. why have you built a bird drone? surveillance, where it's important to not have an intrusive device, but something that is quite — can be obscured and can hide within a flock of birds, like if you're thinking of wildlife monitoring. of course, we have had inquiries also from the defence sector. by mimicking nature, it is hoped that this drone will be able to flap by unnoticed. actual in—air tests aren't scheduled, though, until next summer. so it might be a little while before this bird starts to fly, but in the skies above san francisco, there is an aircraft which is currently flying itself and on board is cody godwin. the streets of san francisco are home to many self—driving cars so naturally, the sky above the city is home to a self—flying plane. this is xwing, a company that has developed an autonomous flying system that handles everything from taxiing to take—off to landing to parking. the system is similar to self—driving cars and uses a lot of the same tech, like lidar cameras and sensors to navigate the skies, while a command centre on the ground helps the autonomous system communicate with the humans in air traffic control. and now that i'm suited and booted, let's see this thing in action. so this is basically a beta version of what they're working on, which means it will make always require a safety pilot on board, but the company is working to be entirely autonomous, meaning none of these by the end of next year. and they're also hoping to get faa certification in 202a. all that the human pilot on board has to do is physically turn the plane on, check that all systems are go and press the button that activates the autonomous system, then it's up to the plane. it does have to liaise with a human in the ground control centre while it's making its way to the runway for take—off, but that's just to ensure it's safe to cross certain parts of the strip. during take—off, it's almost like an ghost is in control because all of the parts are still moving but i'm not seeing what's moving them. once you've trained a robot once, you can build as many robots as you want, they all do the same thing, right? yeah. some of what the sensors and cameras are picking up is augmented over a real—time view from three cameras mounted on the exterior of the plane. the purplish bits off to the side are other planes that are in the area, while the bluish coloured lines in front of the plane are the flight path. on our way back to base, the team decided to let me fly the plane. so we're taking control of the aeroplane. 0k. so he's out of the loop because he doesn't know what you are doing. all right. i don't know what i'm doing. perfect. after a quick lesson on an xbox controller, i was flying a plane for the first time ever. sure, i was just controlling the direction and the altitude but it was a lot of fun. they even let me go as far as a 45—degree tilt. aeroplanes have been equipped with autopilot systems for years already but the system xwing has developed takes that to the next level. if i was just a passenger in this plane, i would have never known it was being flown autonomously. the ride, take—off and landing were as smooth as any other flight i've been on. what makes this possible is the control room. the goal is to eventually have one person overseeing a fleet of flights and sending instructions from control to the computers flying the planes. this plane took its first autonomous flight in december 2019 and since then, xwing has been building up the capabilities of the system. right now, they are planning to use the system to transport cargo. the next step is to fly commercially unmanned so no—one aboard the aircraft, but over unpopulated areas so you're not putting anybody�*s life in jeopardy or anybody on the ground in jeopardy. and if you are flying over unpopulated areas, you're also not jeopardising anybody. the company also sees this as a way to make the process more cost—effective. it's uncharted territory, but to make it even this far has proved to the federal aviation authority it is possible and more importantly safe. i've always wanted to get a pilot's licence, but maybe tech like this means i won't ever need to. but it's still likely a ways off before we see widespread adaptation and faa approval of unmanned aircrafts. drones built at this country house in chichester don'tjust hover above the back yard. a ground—breaking new licence mean pilots can fly these aircraft from hundreds of miles away. typically, drones are not allowed to be flown outside of line of sight of the operator and even when this does happen, regulators only give permission for specific flights on a specific date and for a specific cause. that could be about to change. a company based here has just been granted the uk's first ever blanket licence to make beyond line of sight flights at a moment's notice. the pioneering first flights also rely on autonomous systems. our system maps the world in 3d, in real time, understands that 3d world and its position in the world. that can allow the pilot to stand back and observe. the drone is going to turn, the cameras going to turn. we can go and have a look at those trees over there. 0h, cool! what's the difference between flying it in here and out of the line of sight than it would be if you were stood outside? if you're flying on an oil rig or a long piece of structure, you don't have to keep walking along and looking at the drone, you don't have to have a trained pilot at each site, it could be a nice, quiet office like this focus on what they are doing without the distraction of the wind in the rain. drones fitted with cameras or sensors are particularly useful at locations that are difficult or dangerous for humans to be. parts of this nuclear power plant and the uk's high—speed rail network have already been surveyed from afar. a0 miles away, remote—controlled drones are also helping skanka construction with reservations in surrey. the visual line of sight gives us the opportunity to have fewer people on site. fewer people is less risk, which is a massive plus and busy construction sites. the capabilities of it mean we can cover large areas quicker and it's also more reactive, being able to set a certain task and check beam or a concrete finish and checking the view from above is key. later down the line, delivery of online shopping medicine by drones could change our lives but industrial sites are a good place to prove the systems are safe. i really want to press it. i won't. if the pilot becomes incapacitated, someone just has to press that button and the drone comes home and lands safely. cesda, along with amazon, boeing and volocopter are also working with the uk's aviation regulator, shaping rules that may one day permit drones to transport human passengers. the software doesn't know if it's carrying a camera or a human in a drone taxi. we'll start with simple and end up withjetsons' flying cars. after i go on a simulator, i don't think i should be flying any precious cargo. i don't think i'm going to be coming for anyone because my job anytime soon. i'm quite nervous, even though isn't real! i'm going to try to get through that without crashing. argh! i bit more practice needed there! on a similar theme, let's talk about how your deliveries are going to be dropped off in future. will it be by drone? by cute delivery robot? or by an overworked human driver? we'll, this place have found a way to combine all three. the academy of robotics have treated a self—driving electric delivery vehicle. it's fully road legal and houses 12 cameras and a number of sensors to tell when it's going, not to mention it features a slew of solar panels to constantly power and charge it up. in this version of kar—go, there's space for an operator to make sure everything is running well and that will be phased out once they can connect to the car with confidence remotely but the company says it only takes one pass through an area before kar—go learns it and then it can drive around comfortably with no help. we are told this thing can deliver up to 48 packages a day and hit up to 60 miles an hour but we won't see that speed here as we follow it through a local neighbourhood during its trial run. itjust looks like a really small racing car, but with just a whole lot of green, plastic trim. i guess it doesn't matter how it looks, it's about how it functions and right now it's functioning fine, it's going down the route, it's driving well, avoiding parked cars, it's impressive. it almost looks like someone is driving it. it then completed its run of deliveries with no trouble at all. but this isn't the only vehicle they've created. the company needs a command base to control everything from as well, remotely connect to the car and make sure everything is going all right, intervene if need be. well, they put that on wheels too. inside is a system built to process what they can't see in real time, a driving seat so someone can manually take control of a car if need be and even space to be load it up and move once it's done. but this was a late innovation. before anything else, the company spent three years focusing on just the software. most cars are looking at the road is one giant scene and then trying to figure out whatever it's is doing but when we're driving us your eyes are darting from there to there and you zoom in, zoom out, and you do all these little things so we just simulated this in software where we make a cluster of ms doing little things and together they synchronise. and how they train these ais is not typical, either. instead of gathering tonnes of data to teach them, the company compute its scenarios, giving many driving possibilities to teach the car. this is the only self—driving delivery car out there. over in the states, there are other vehicles, quite similar in the way they look, work and drive about like kar—go. but the company is looking to do more than deliver to people's homes. we are on the raf brize norton base, watching as their car delivers items across the massive site. for security reasons, the company couldn't scan the base as it normally would a neighbourhood but they've gotten around that. what they've done is preloaded the bot with pre—existing data about similar sites and fine—tuned it to the specific set up, like we are certain places are and a traffic light that's green here actually means stop. weird that, isn't it? that, coupled with the on—board cameras and sensors, means it can go across the relatively unknown site without any pre—training. so this self—driving car has a lot of promise, potentially the future of delivery for consumers and businesses, too, but with humans are still needed behind the wheel for safety�*s sake, it may be a while before we see these swarming our roads. and that's all we have time for in click for this week, from iceland. you can find out what we're up to on social media. we live on youtube, facebook, instagram and twitter. thanks for watching and we'll see you soon. we have quite a big change on the way in our weather, something cooler and more unsettled through the week ahead. make the most of today if you like warm weather because it is another one of those days temperatures will be above where they should be for the time of year. a lot of dry weather around — but rain moving into the west thanks to this stripe of cloud on the satellite picture. this is a frontal system bringing rain into northern ireland. initially that rain will push eastwards and behind this front, a cold front, we change the air mass, we change the feel of the weather and lose the orange colours and get the yellow and then the blue shades and things will turn markedly cooler over the next few days. that rain moving into northern ireland through the afternoon. some heavy bursts with strong and gusty winds. some of that rain getting into western scotland. eastern scotland, much of england and wales staying largely dry and dome spells of sunshine and just the odd rogue shower. temperatures in the high teens and low 20s celsius, up to 22 or 23 in places. through this evening and tonight that weather front and band of rain will track east and notice the bright green colours. that indicates there will be really intense downpours accompanied by squally and gusty winds. that rain not reaching the eastern side of england till dawn. it will be a mild night and mild start to tomorrow but the rain will reach all remaining areas as we go through tomorrow morning. very soggy start in the east and as that clears skies will brighten and we will see sunshine and showers racing in from the west and some will be heavy and possibly thundery and it will be quite breezy and it will feel much cooler and fresher. top temperatures between 111 and 18 degrees — much closer to where we should be at this point in late september. low pressure takes charge this week. this weather system promises persistent rain for many on tuesday and will be accompanied by strong and gusty winds, some gusts of a0 mph to 50 mph in exposed spots. temperatures ia to 18 . wednesday will be cooler still. but it will bring something of a dry interlude. more unsettled weather for the end of the week, some rain at times, some brisk winds, and it stays cool and autumnal. good afternoon. the transport secretary has insisted there is no shortage of fuel and has urged drivers to fill up only when they need to. it is days after queues at some filling stations. the government has announced a temporary these are scheme for hgv drivers and poultry workers in an attempt to limit supply disruption to food and fuel in the run—up to
