the leasing to stop at every 2nd address for wes, yet of a wasted for a package that never arrives because the driver is stuck in traffic for hours, polluting the environment with the exhaust. good news. there's a solution in the though it will require new rules. the last one today show mr. young from serbia, a new mines, fox protests. are we running out of oil? how long the reserves lost? and a miracle material, that's the base stuff. the cell drones have long been seen as the future of delivery services from parcels to food and even medical supplies. less traffic,

fewer emissions delivering even to remote areas. sounds perfect, right? well, not quite. this guys above us are crowded with more and more aircraft. if thousands of drones are added to the mix, how can they all share the same air space, especially in densely populated urban areas? the idea of sharing the sky is simple. the lower aerospace belongs to drones, while higher altitudes are reserved for air planes, just like roads on the ground, highways for drones will be a central drone car doors are currently being tested and developed around the world . britain is working on a pretty big one. a 265 kilometer route connecting several towns and cities. drones can enter the card or at any point the a monitoring says to move the tech to potential collisions and

redirect the unmanned aircraft. it's still a work in progress, but once completed, it promises to be a significant step forward in drove delivery. the system is set to be available for commercial use by early 2025. i think that's one of the best ways we could organize a lot of drones flying and one aerospace at the same time because we do the same thing with mandation and most man aircraft, they don't fly wherever they want. they follow court orders and miss scott drove the car. there's just one piece of the infrastructure puzzle. a major challenge would be integrating drones victim or as based system, because that's the main uh, safety aspect comes into play. heavier drones require a remote id, basically a license plate for drones. they can be tracked and assigned to an owner, crucial in the case of accidents. for example. the drones are also controlled by

a detect and avoid system to prevent collisions. after a hopefully safe journey, they need somewhere to touch down at the moment. drones are still not allowed anywhere near airports, but in the future landing areas could be added to them. that would also be arrival pads and city centers. but even if you live in this city, you probably won't get your delivery at your doorstep. you still need to go somewhere to pick it up. if the landing spot is close by, you might be notified by this tell tale sound to the most people when they think of a drug, they should think of a small di john quad copper. it doesn't make a lot of noise, but if you're doing something for drone package delivery, it needs to be a much larger unit. it sounds like homeless long hours running next year has when amazon tested drone delivery and college station texas residents complained about

the noise, prompting the mayor to write a letter to the federal aviation administration. amazon insist that the new drones are quieter. let's assume everything works out. drones aren't too loud, flying happily and they've drone corridors monitored by sage systems and kept away from airplanes. that solves lots of issues except for one major legal, one in countries such as the us and india. the aerospace above homes belongs to land owners. we are still in a piece of of that is our decision making to be done as to what might be done. so i sure i could rich or above or rich the drawing scan the in the us, the idea of a marketplace has been introduced to offer land owners on monetary incentives. they can rent or sell their air space to be used by drones. designs the challenges of

integration. a global market for drone services is forecast of growth significantly in the years to come to one country that wants to be part of that is india. with liberalized regulations and incentive scheme, the country wants to become a drone hub. by 2030 we can see it approximately on on the 2013 we might have a basic info aspect of every c, r, and integration of drawings. that mind has been in a limited amount of so when will your pizza be delivered by a drone? not for a while yet. although the technology is advanced, various uncertainties remain regarding regulations, safety, and disruptions to everyday life. and honestly, we'd better take it slow because drones dropping out of the sky could cause serious injuries or material damage. drones could revolutionize delivery services that whether they will actually deliver to your doorstep isn't clear yet. and who knows

whether it's really safe to have countless drones buzzing around in the air. drones lead powerful batteries to fly to. and these usually contain lithium. but no lithium supplies are limited. china has had the monopoly of most of the world's reserves fee is to decrease reliance on china the and will soon also be mind in europe too. but at what price in serbia residents via it could home the environment and costs and then likelihood lod, google kind of inches is 7th generation farm or he tends to his to doesn't cows every day and loves village live here in going you and that leads bobby most of the we've cattle farmers and every year we sell about a 100000 leaders of milk, my family, my 5 children, we live from that and we don't plan to change the thing on the middle. the medium

was way navigate usefully. it's just like many other farmers on the western edge of serbia, but a global mining giant does have plans for the yadda valley due to its large deposits of lithium, a key component and electric vehicle batteries. rio 10 to is bought up land and farms across the valley. it plans to mine $58000.00 tons of the metal annually. enough to supply batteries for over a 1000000 vehicles. we're aware of savvy as rich resources and the enormous potential with confirmed reserves of 158000000 tons of lithium branch on all of it . and it has that to be the government insists mining operations will meet the use strict environmental standards, while serbia isn't a member id seeking to join the block. so most of the only state institutions can control this in the suit. the investor will say, i'll give you the documentation,

that's the basis of all what and also, and then up to the government of the republic of serbia and to monitor the public is to be absolved to share control. many in the opposition don't believe these words member of parliament, alexander giovanna vege takes part in mass protests against the olivia mine. is it godaddy? everywhere we attempt to has been around the world. it is left behind devastation and misery, and that's wake, including civil wars. and the destruction of nature and cultural monuments here the quite a name a bit his skepticism is shared. this expert has seen studies on the potential environmental impact more up for that. most problem. you have to tell us about the just talking the or is mind with the help of intensive subterranean explosions. and the lithium processing will involve $1100.00 tons of concentrated, so fewer gas in the daily, it will lead behind a mountain of ways that will pollute the environment for century also be met quite so they called him and that's what he is a guide you will see what the civilian,

okay. rio 1030 says it's willing to talk. it's invested 600000000 euro so far with plans for a further 2000000000. the company claims the mining will be done using precise planning and environmentally friendly methods and create thousands of new jobs. while i want to assure everybody this project is 100 percent size, it's been designed to the highest standards in the world, and we will not be a big hole in the grand. in contrast, we're in, i'm the grandma on agriculture co exist on the surface with them on together. and in terms of what we would not impact any agriculture, water, any drinking water, we would not be poisoning any water sources. but it's not cool kind of edge and his neighbors don't trust any of the parties involved. the corporation, the government, the courts, or the state controlled media. i found the police always disappear about whether the mine is coming or not the dollar. they should be the not, of course, i'm against the mind. it's not good for us. there's always an exception to be and

that does it when nobody lives will be left with no will test the mood and the yadda valley is tons. this farmer is determined to keep his land and his livelihood . not only so the nichol, you mustn't take up these graves and i'm prepared to sacrifice my life to prevent that. that's boise, what zillow's name is that the one that sits on at this compromise on the list of mine is a long way off this trust and started b as institutions and rewards. vento is to grade so the government has announced that it will approve the mine in 2 years at the earliest the future may be electric, but they're still a long road ahead. e v have yet to become widespread, and most of our economy is still based on fossil fuels. so will be reliance on oil for a while to come. so based on various studies that to be used,

should we have run out of oil long ago. let's check it out. in 1956, a g, a scientist for a show and professor at stanford projected the global oil production with peak around the year 2000. this came as a huge shock at a time one oil was driving more and more of the economy. some people thought it would mean a global financial crisis and others a full on apocalypse. since then, predictions about peak oil have popped up again and again. supply problems were supposed to start in 2011 for the effects noticeable by 2015. there was talk of high prices for food and fuel, supposed to impact agriculture and electricity. but none of this ever happened. the supply problems that everyone freaked out about never came. so what did happen, and should he be worried about running out of oil? first, looking at this question now is completely different from the decades ago, because there have been huge changes in our lives, in the early 2,

thousands. we weren't really thinking about life, that fossil fuels, electric vehicles, for nearly unheard of, to an end of our oil supplies seems like i just central crisis for the planet. the going awareness of climate change, renewables of taken off, and the amount of them in the mix of guns usually is not cheaper to generate electricity from solar and wind then from the cost of or there's also a way more attention on electric vehicles. 14 percent of new vehicles sold globally and 2022 or electric compared to just 5 percent and 2020. even the united states and china to huge polluters are making has the investments into green technology. and something pretty special happened in 2023. when we're looking at renewables, investment, which clearly is been growing rapidly in trends, trends to net dot from top to field in 2023. far see to maybe the stock doctors or any set to widen. one not much would move without fossil fuels, and oil, in particular, the future of renewables is looking brighter and brighter. and that is me the end

of oil take on a whole new meaning to go up to say about 15 to 20 years back. there was a concern that bio supply is going to be run out of wyatt. now the concern is somewhere there from the ridges that really hit their p. carter applied towards the demand. this is a really huge shift. in october 2023. the international energy agency published a report predicting the end of oil and other fossil fuels. only this time, the end of the peaking demand not supply, and is predicted to come in 2035 demand and low supply means a high price. low demand and high supply means a low priced oil executives around the world were up in arms over the report because less demand, but the same amount of supply to mean following prizes for fossil fuels and less profit for the industry. this is a big deal since demand for oil, it's been growing every year except 2021 covet hit. this wouldn't mean that we wouldn't use fossil fuels anymore for that it would become much harder to justify new fossil fuel projects. because our supply of fossil fuels is doing great

the oil, and i'm probably not going to the base of the kind of the reserves we have about 40 years old. i am. and that doesn't even count on the new plan project. this is mostly thanks to newest technology called hydraulic fracturing of practice. tracking is a process that involves injecting a slushy of water and chemicals into rock, getting tons of tiny cracks. this allows oil and gas to escape and be collected at the surface. the waste water is then often injected deep under ground, which can contaminate the local environment and cause of earthquakes. fracking took off in the united states in the early 2, thousands and the country now produces more oil per year than any other nation in the world. so much, but it's affecting other countries to solve the area or are you a new york corvettes? and i'm actually right now because of so much over supply the market staff, reducing block less than what they can produce. on the one hand, they might have an over supply of oil and on the other plateauing demand. also,

investors turning away from fossil fuels. the oil companies are used to expanding and major oil producers like show exxon until it's how the energies are also bedding on rising demand. data suggested that to companies, i think that means the p. we're increasing that oil production, total energy, stated it was full costs to spend 25 percent of its carfax to 2022 and renewable that tricity. so when you look at what that includes, it also includes some kind of gas fired power. they may seem like they're shifting towards the renewables put, they're actually still banking on a fossil fuel future. the business operations on changing particularly, or the pace needed that will says it will be against policies that would polls that change or bringing about quicker. but at the same time promoting this very public narrative that they are doing well, they can state on the oil companies like russian ross, nest, and savvy around color, also betting on future money from fossil fuels. even though projects approved now may never be profitable. new sites take years to build up infrastructure and to get

ready for drilling and financial times they might become stranded assets, something that was invested in that became obsolete. some countries 30 to 40 percent of and talk fiscal budget could be at risk as the foundation on falls quite an old price is full. that's going to have a massive impact on the economies. these countries increase the living standards of those in these countries, and that impact to also help individual citizens directly. many pension funds around the world are invested in oil and gas. these companies fail spectacularly. millions of people could be plunged into financial insecurity in their old age. so based with the end of oil, it seems like investing in renewables at the smart financial decisions. they're cheaper and there's less risk of new projects becoming stranded and unprofitable in the future. all of that is going to move away from way as much. there's not going to be overnight because according to all predictions, we're going to continue to meet fossil fuels for a while. they're used as

a backup power when wind in solar are running and widespread. nuclear isn't likely to come on line and time transport and energy storage also need to improve for us to be able to quit them entirely. but the more investment goes in, the more renewables improve, and we desperately need that to keep existing on this planet. it's critical for all future that we keep making breaks. what you say, renewable energy's well, quantity or the potential for mass adoption is important. qualities to, for instance, finding ways to get more energy, saving yourselves before using materials whose extraction doesn't harm the environment. it's like perhaps skype for example. but watching this tiny solar cell might be about to revolutionize solar energy. as we know it, it's way more efficient than you know, spend that silicon solar cell. it can be easily synthesized and doesn't need to be mind like silica, as it can work on in the field to poly as not how speak up,

but it also it can go on your roof. say hi to this crystal structure. coolants paradox caught it, promises improvements to solar cells that are almost too good to be true, to understand why they are so superior to your standard silicon. so i went here, the helm holds institute invalid baseband researching, cross cards as a sign of solving material for more than a decade. hey, how are you doing? i'm good. let me see if i search here. and this is the guy in charge of the research, steve i, but he even said world right codes for the most efficient parole, scott solar cells. so on a very basic level, what does for us kind of look like the temper off good is a very generic term for a specific crystal structure, right? you can see that here over there. so the christmas structure has the x 3 formula. and like each component is a certain i the element for

a molecule. one of the most common combinations in the structure is methyl ammonium as the a on the corners, the metal left for the be in the center and chloride or iodide as the x which form around the metal. but there is a vast range of materials that can be used 10 combined, and it's quite wild how easily these can be put together. so this is 11 volume. and before we do that, security 1st, as we're going to work with toxic less with one of the of all, when i call these you look a bit like a met scenario. okay, times who gets an hour based materials? matthew makes this methyl ammonium, chloride. and let's iodide so latex 8, our abs, fried crystal structure. so what is now the advantage of these materials compared to silicon? so, i believe that one of the main advantages of prostate or silicon as material is the

ease of processing. so silicon is something that is relatively energy intensive to fabricate, but this is something that can be done at post to room temperature. so it doesn't require much energy. so it's easy to do. everything is relatively abundant. and so, um it, it's, it shouldn't be bottlenecked for production. now that we have the space materials we need to produce on solving corrupts. got out of it. matthew does lose by using a technique called spin coating, but perhaps kind of sort of sales can also be directly printed onto surfaces using similar processes to those needed for printing. newspapers. spin coaching however can be tedious. matthew accidentally dropped the glass, not a big problem in the lab environment, but for commercial production, this is not viable. matthew gives it a 2nd try. and this time everything works. after this been coaching, it goes onto

a heating plate. and the darkening shows us that the crystals are being formed. it works the same way as when salt water evaporates and you start to see the salt. there are sales like this one here, which i only made out of the rough guy, but in many cases there's this cindy can layout beneath. so the sales i called 10 themselves and looked like this. right now they have the most promising candidates when it comes to increasing the efficiency of solar cells. but at some point, it might be also possible to abandon the silicon completely to test that 10 themselves. the efficiency, the research has at hand holds institute, use this on simulator. it determines exactly how much sunlight is converted into electricity. what kind of efficiencies it we just measured. so when we measure almost 30 percent, it's a quite nice achievement. why don't they tend them so a cell reach that much more efficiency than single junction so. so sometimes all

samples may much more use of the incoming lights, so we have a long so long spectrum there's a lot. so they shanell this back from the parent sky. so also in this case makes use of the visible wavelength. so everything which we can see by i, it's been converted into pay of care was canceled on sale into electrical energy. whereas the infrared light passes through the peril sikesdale and he's been converted into silicon salsa which is quite deficient in converting in for red line . so the share of the spectrum in each cell is very efficient. and the reason it doesn't sound like that much, but i could tells me that this way, roughly 50 percent more sunlight can be converted into electrical energy. so more overall sunlight can be solved by con, by any of these tendons. so yeah, because before they go into serious productions, there's a lot of stuff that needs to be a major issue is the stability of the parole. scott structures using 10 themselves

of cells. pearls cod structures easily put together at low temperatures as we saw earlier, but they also come a pop easily. even the charges that travel through the perhaps cutting the solar cell can for a defect and destroy the power of god. structures. also external effect, as like moisture, heat, oxygen, and u, v light can break it down further and quickly decrease its records breaking efficiency. this whole process is called degradation, which researches and companies are trying to fight with different forms of encapsulation. it's yields of the solar modules from external influences and is an essential step for commercialization. the queue sales, which is part of a european academia and industry partnership plans to develop commercial sized manuals with an efficiency of 26 percent of a lifetime of. so it's a yes. ok sport, p v. a company founded by oxford university graduates,

has reached an efficiency of 28.6 percent and supposedly solve the degradation issue. already bought me, the company has published verifiable data yet nor is there a lot of published research on real world outdoor tests. these are a lot of so that you test. yeah. wow. this is catalina. oh, she oversees the degradation tests of 10 them. solar sales at the helm holds institute at what kind of stability is we currently looking at here, sometimes to fail after a few days old. but sometimes they last for years. literally measured the loss of 20 percent and efficiency and just hop. yeah. it takes to look in solar cells roughly 20 years to reach that level of degradation. some companies say they've already fix this issue and ready to go to market next. yeah. do you believe that's possible because sometimes here we must also have conferences,

but they normally don't show the data. it's all very secret or 10 them solar cells would also need to price match existing cells at hospital experts view as difficult to achieve as costs for electricity from sola have declined by 89 percent since 2010. it's no more expensive to install so they can sell a penalty then to produce them. solar panels, those have a rates potential, but there's still a lot of things that need to fall into place for them to work. and i'm really, really curious if they're actually going to be on the market next year or ready for another edition of mays where we have playing high and freshly energized. let's do away with the old head into a sonia right. so if you see you next time the shredding band in germany,

the killing of male chicks is prohibited by law. but where the roosters now animals rights activists following the trail. they are dumped in poland or end up in gardening and chicken markets for cheap need. is the good law causing more problems abroad? next, on d w. how's tiny brains do really and things? insects are smarter than we thought. the researchers are investigating their true abilities and making a sounding discoveries. these little creatures are pretty clever. martin insight into l is on d w the

the do you know which of these 3 industries has the highest c o 2 emission rates? would you guess the concrete transforming business to live is on to figure out what's the real new deal? it's just reimbursing the watch now the you'll see about the video that goes enabled other data media and legal law give a lot of your time. but again, i will stop into that and i'll give you a go on would you? are you able to order that? i'm jo made any of the current key, more people than on the move world wide in search of it. that's a nice to jump. be able to use them in a decade to mess with the guns already already a few megs of appears and mid afternoon. does our pearson minutes to school or is

that almost 3 gets expose? go to lunch. when you find out about all the story info, migraines, reliable news for language, wherever they may be. the for 2 years, many a cartons in germany have been marked with labels that say no mail checks, colt sounds good, right? before mail checks would be shredded since they serve no purpose in egg production . so called brother roosters of commercially bred hens cancel a ex. there meet isn't popular with consumers either time. no one wants the rooster on 5. he said with this read line, i'm just not plausible to raise the brother copy center, but they still germany's former agriculture ministry lily i think.
