house are old policies, the page, the guns in assigned a set of starts october 12th on dw. 2 do you sometimes get mountains of packages that has from stressed out delivery people who only seem 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 exhaust good news. there's a solution in the though it will require new rules. the last one today show victim from serbia. a new mines folks protests. are we running out of oil? how long the reserves lost?

and a miracle material that's a base desk system. 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. ways for drones will be essential 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 carter at any point the a monitoring system will detect a potential collisions and redirect to the unmanned aircraft. it's still a work in progress, but once completed, it promises to be a significant step forward in drill 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, lying in one aerospace at the same time because we do the same thing with man deviation and most man aircraft. they don't fly wherever they want. they follow court orders. and ms. scott, the drawing corridors are just one piece of the infrastructure puzzle. a major

challenge would be integrating drawings victim r. s b system, because that's the main uh, safety aspect comes into play. heavier drones require a remote id, basically a license plate for drones, or they can be dragged 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

the most people, when they think of a drawing, based on think of a small di john clark, copper and it doesn't make a lot of noise. but if you're doing something for drone package, delivery needs to be a much larger unit. it sound 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 insists that the new drones are quieter. let's assume everything works out. drones aren't too loud, flying happily in their 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 added that is our decision making to be done as to what might be the sure rich or above which the drones can the in the us, the idea of a marketplace has been introduced to offer lando and there are some monetary incentives they can rent or sell their air space to be used by drones. besides the challenges of integration, the 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 scale, the country wants to become a drone hub by 2030. we can see it approximately on, on bringing 13 we might have a basic infrastructure of every see or an integration of drawings that on demand. as based 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 need have a full back to ease to fly to. and these usually contain lithium, but known lithium supplies unlimited. china has had the monopoly of most of the world's reserves, is to decrease reliance on china the and will soon also be mind in europe to but what price inside the residence via it could home the environment and costs and then likelihood lod,

google kind of which is a 7th generation farmer. he tends to his to doesn't cows every day and loves village live here in going, you know, needs, uh, i love you must sit for the cattle farmer 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 a thing on the middle. the medium was way navigate use for it so that they just like many other farmers on the western edge of serbia. but a global mining giant does have plans for the valley due to its large deposits of lithium, a key component and electric vehicle batteries. rio tend to has bought up land and farms across the valley. the plans to mine $58000.00 tons of the metal annually. enough to supply batteries for over a 1000000 vehicles. we're aware of savvy is rich resources and the enormous

potential with confirmed reserves of 158000000 tons of lithium bar. it's on all of it and it has to be. the government insists mining operations will meet the use strict environmental standards. while serbia isn't a member, it's seeking to join the block. so most of the only state institutions can control this industry. the investor will say, i'll give you the documentation, that's the basis of luck and also, and then to the government of the republic of serbia to monitor the weakest to be adopted. a 2nd tool, many in the opposition don't believe these words member of parliament, alexander giovanna. vege takes part in mass protests against olivia mine, to the godaddy every where we are to into has been around. the world 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 practice problem. you have to tell us about the just talking the over his mind with the help of intensive subterranean explosions. and the lithium processing will involve 1100 tons of concentrated. so if you're a gas in a daily, it will lead behind a mountain of ways that will pollute the environment for century. also be met quite a bit called him and that's what he is a guide you. is you what the civilian. okay. 3. 010. terry 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 high standards in the world, and we will not be a big hole in the grand. in contrast, where and 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 it changes, neighbors don't trust any of the parties involved, the corporation, the government, the courts or the state controlled media style is always disappear about whether the mind is coming or not the dollar, they should be the not, of course, i'm against the mind, it's not good for us, is always an exception to be in the 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 nickel, you mustn't dig up these graves and i am 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 base 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 there's still a long road ahead. eaves 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 we use, should we have run out of oil long ago, let's check it out. in 1956, a g, a scientist, rachelle and professor at stanford projected the global oil production with peak around the year 2000. this came as a huge shock at a time when well 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 try to be worried about running out of oil 1st, looking at this question now is completely different from 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 growing 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 fossil fuels. 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 have 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 part. see to maybe not stuck 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 mean 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 wire. now the concern is somewhere there from the ridges that really hit the p card applied towards the demand. this is a really huge shift. in october 2023. the international energy agency published a report predict in the end as well, and other fossil fuels. only this time, the end of the peak in demand, not supply, and it's 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 their report because less demand for 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 it, 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 projects. 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 has been 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 that it's affecting other countries, 6. so the area or you or your corvettes, and i'm actually right now because of so much over supply the market. they're producing block less than what they can produce. sun one, henry 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 and total energies are also bedding on rising demand. data suggested that to companies, i think that main p p were increasing that oil production. total energy stated it was it was full costs to spend 25 percent of its carfax to 2022 and renewables in that tricity. but 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'll be against policies that would all stop change or bringing about quicker. but at the same time promoting this very public narrative that they are doing well. they can state onto oil companies like russian ross, nest and saudi 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 to 40 percent of and talk fiscal budget could be at risk as the foundation of folds. 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

faced 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 the time of order from all of those months. there's not going to be overnight because according to all predictions, we're going to continue to need fossil fuels for a while. they're used as a backup power when wind and 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, some 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, 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 come the environment. it's like perhaps skype for example. but what is this tiny solar cell might be about to revolutionize solar energy as we know it, it's way more efficient than you spend that silicon solar cell. it can be easily synthesized and doesn't need to be mind like silica, as it can welcome to 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, but 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. they've been researching cross cards as a sign of solving material for more than a decade. hey, how you doing? good things here. and this is the guy in charge of the research, steve. i wish he even said world records for the most efficient pearl scott solar

cells. so on a very basic level, what does perhaps cut 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 cost of the structure has the x $3.00 formula. and like each component is the sort and i, the element for molecule. one of the most common combinations in the structure is methyl ammonium as the a on the corners, the metal left for 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 and combined, and it's quite wild how easily these can be put together to this is 11 environment . before we do that security 1st, as we're going to work with toxic less with one of the of all of a nice colleagues. you look

a bit like event scenario. okay, times who gets in our base materials. matthew makes is 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 a bottleneck for production. now that we have these base materials we need to produce, i'm solving perhaps 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 salt. there are sales like this one here, which i only made out of for rough guy, but in many cases there's a silicon layout beneath. so the sales i called kind 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 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 efficiency that we just measured? so when we measure almost 30 percent, it's a quite nice achievement. why does it tend them solar cell reach that much more efficiency, even single junction? so sometimes a lot of samples may much more use of the incoming lights, so we have a long so long spectrum. there's a lot of cells, they shanell this spectrum kind of the parents kind soul. so in this case, makes use of the visible wavelength. so everything which we can see by i is then converted into pay perils console on sale into electrical energy as far as the infrared light passes through with the parasite sale. and it's been converted into a silicon solar cell which is quite deficient in converting in for red line. so they should be on the spectrum. and each cell is very efficient and the reason it

doesn't sound like that much, but i can tells me that this way, roughly 50 percent more sunlight can be converted into electrical energy. so more overall of sunlight can be saw. you can find 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 pearl scott structures using 10 themselves of cells. pearls cut structures easily put together at low temperatures as we saw earlier, but they also come apart easily. even the charges that travel through the perhaps cutting the solar so it can create defects and destroy the power of god. structures . also, external factors like moisture, heat, oxygen, and u, v. lights can break it down further and quickly decrease its a 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 to sales, which is part of a european academia and industry partnership plans to develop commercial size modules with an efficiency of 26 percent over a lifetime of so 2 years, a box for tv, a company founded by oxford university graduates, has rates and 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. so sometimes they last for years with this,

teen measured the loss of 20 percent and efficiency and just hop. yeah, it takes to look them, solar cells roughly 20 years to reach that level of degradation. some companies say they've already fix this issue and are 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 sales at hospital experts view as difficult to achieve as costs for electricity from solar have declined by 8 to 9 percent since 2010. it's no more expensive to install so they can sell a penalty then to produce them. so upon themselves 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
