are up to date, but stay with us here, auntie w up next planet. a asks why we aren't all flying in electric plains by now. for more news, you can always visit our website. that's a d, w dot com and follow us on social media at p. w. news. i'm david levitz for me in the whole team here in berlin. thanks for watching. the name is the calls back. saved loud. thank you so much for joining in. welcome to don't hold bad. a lot of people do that. it's called about saying it aloud. that's what it being nosy bay like. good everyone to kings to check out the award winning called call. don't call back. january 2021. the attack on the united states capital, thousands of people took pods and among them some of these manipulative voices. our

former high ranking military leaders wanted us veterans turned their backs on democracy. and what does this mean for the upcoming election? the enemy within starts to lie 12 on d, w the, the best throughout the world. i think i flew in this electric plane, who's joining you could argue, started in 1883. that was the 1st electric aircraft that ever to around 20 years before the right products along the line of funny and useful aircraft scheme, often including unmanned aerial vehicles in drones and let the thought that today, oh my god, this is the 1st flight of 510 to fly electric and it was right, the dozens of projects around the world and now figuring out how to finally make electric aviation reality and some the speed of downright funky that convinced the

time has come. some companies already settings tickets. the silent cheap to operate and potentially up to 90 percent more efficient than just you with that across on a plans or just but as you can see here, it's really easy to get caught up. and all the hype, they've never really worked at security before. so i'm in northeast and sweden to find out why we all know slang. electra gaps. it won't surprise you to hear that. how we fly today needs to change, if you shouldn't mix up for around 3 percent of silverland missions. and okay, that really doesn't sound so bad. but by 2050, that numbers projected to rise to over 8 times. but, and there are no real ways to fly pollution free. so it is, why are you, what is the most promising solution? so a vision pollution of biofuels, more broadly sustainable aviation fuels. they're mostly made from non petroleum products like bio mass. so out again, you can basically just swap the fossil fuels in here for biofuels. i'll make

a blend. but we need so much of with the scaling up is very hot and the lands that they use for other purposes like screwing food or saving far. and then there's also hydrogen to think on this, especially hydrogen made sustainably, a lot of prototypes are being tested. electric plans are a 3rd option, and they can make a really compelling case up here where we know we, we run off hydro power or wind power. so then to consider we have is this sustainable renewable. so for us that's, that's the demo sustainable we can do right now. so the for us, this is you on know, but as going of a, the issue and one of the only people flying airplanes every day. when a vision screwed in sweden with future pilots, i've been chained and flying electric lands we, we want to sort of me the industry into something new and showing that it's possible to find new products with high quality and the sustainable. what i mean is

i'm quite confident that it's going to happen. i mean, i feel confident in the way that i'm an electrical engineer as well as one major difference compared to maybe 10 years ago with stuff there's proper money being put into. that's because if we get electric engine side, we, when the efficiency get electric engine is going to be 3 times more efficient than those that he was supposed to the fields. and of course they don't degrade the quantity during operation. the purpose for the ballast, they fly here doesn't mean much electricity. it takes around an hour and a half to charge on which is going 545 minutes with the result of 30 percent patchy is mostly used for pilot training or private key. she left the airport has a one mega what charging station, which is enough to judge a small fleet of electric plans at the same time. so i get faster tough to get in. so house 1st is easier. i'm ready, correct. i've got the

fast this is a super light plane, but it can only go to people with no have luggage to go. any big o e plans are faced with a big problem. heavy batteries, even though they've been a lot of advancements and thought cheese, we actually haven't come that far. because successful for cause, roughly for an electric chevrolet boat to drive the distance, a honda civic, good on a full deck with you, with the battery would need to be 17 times heavier and cost to stay on the ground. so the weight doesn't matter so much, but for boeing, 747, to fly from say, london to istanbul. batteries will need to be this much heavier than a full time. this just going to work, since this wouldn't be 10 times heavier than the heaviest payload ever. lifted when you're storing energy, you need a very high level of energy density. that's good,

garry, how does the app, what's program at the u. s. department of energy use national renewable energy lab or, and petroleum and petroleum related products or petroleum. dr. products like biofuels have a really high energy density when compared to the energy density of traditional fuel batteries fed very poorly coming in at only 2 percent. but conventional aircraft, we fly and today i'll be this for jet fuel. it all started with a design off, and the 1950s, they mean propeller plans the most popular at the time. and still by an end to it looks like this. the performance characteristics between those 2 aircraft where the turban was slightly faster, but it couldn't go as far. and, you know, you've got marginal gains by doing that. and then 5 years later, they figured out for different sizes, for different configurations, all of a sudden it makes sense to use these because of now how like you can make a service. over time this though bye in or cuban wing design became vastly more

efficient or clear. we know if the res, today's deadline has been almost 50 percent less fuel passenger kilometer, then they did 50 years old. but they have a better engines improve enter dynamics and a lot of other often invisible changes. but the thing is, this design has peaked in the way it's very hard to become more carbon efficient unless you squeeze even more people onto already very died plans. so governments and many of the industrial going back to the drawing board to redesign in another 1950 style design of it's a really, really interesting time in that sense because things are up for grabs. again, this is done by a vision expert who looked at on the ground infrastructure to support the transition by working together with detroit. but we looked at 2 main modes of operation for doing that one, which was a battery charging system, so where the battery would remain fixed within the craft. you would plug it in as if you would like

a normal device. you would just charge it. this would be the simplest way operationally speaking, but they also found the charging would waste precious time when current air traffic relies on a quick down around bands would ok by limited space in the airport. and of course, the amount of power needed would take away significantly from the city's grid. the 2nd sort of mode of operation we looked at was a battery swapping system. and that would be where you would have pre charged batteries. and then when an across came in, you would remove the battery from the frame and then swap it with the one that had already been pre charged. this would save space and time, but it would require a lot of specialization, which we currently don't have anywhere. and it wouldn't be a big risk. meddling with an airframe is always dangerous. and there's also the major risk of files from holding so many batteries in one place. a site of the 2 systems we. we favored the battery charging system. but we were very aware of the potential limitations, but that compose,

so not easy. the now i mean you can find your. so what do i do if you want to know if it go down for just x board? if you want to think back to this is what the 1st plans to be certified, but this is another huge shot and what a vision has compared to cause being certified for safety. so everything takes time for our in the testing, including for battery safety and the use long certification process. but this january the yorba in solomon bush with the idea of more e plans for shot and mid range flights. they just bought of a while ago to got 90 percent of emissions from transport by 2050. all right. thank you. all those crazy sit on the equity. okay. the company that means that the district is now working on a full cedar plan and the already big ones, a plane called olive secretary, 9 passenger,

the 2 crew members seem to be close to commercialization, promising to fly around 400 kilometers hot aerospace and sweden has a proof of concept aircraft that looks like 25 passengers up to 800 kilometers by 2026. when you look at, if you think about their existing cargo routes that use small aircraft, their existing communities, that they're only connection is a, as a 9 senior, correct? unless they take a ferry for or 6 hours type of a situation. and those are real existing route that have to be either subsidized or paid for by by communities. this is the main application so far, and it is significant. in 2020, the us spent $326000000.00 to subsidize the costs of across to smaller apples. the don't see a profit ambulances at taxis and small cargo planes also need only small across the child has ordered 12 plants for low emissions postal deliveries, which can help local noise and quality too. but let's put this all in perspective

with everything that electrification can do. now, based on current battery tech and operational challenges, a study by the international center on team aviation estimates, but electric aircraft called govern 9 percent of the coming to markets. that slides with more than 19 passengers and distances shorter than 500 kilometers. but this only accounts the 0.002 percent of global deviation. by 2050, the estimated could be up to 0.2 percent, which is still small. what am i talking about? carbon emissions. but this is purely electric. we're talking about equals a house versions of hybrid. so you could have a series hybrid which is where essentially fuel is used to power an electric my to which then powers the craft. so you're using fuel to charge a battery, essentially, and then you also have local power, low hybrids,

which is where you have the electric mertsa and the fuel source, so kerosene to hydrogen boats being used for propulsion. i couldn't imagine this tiny plan getting much bigger in the next 2 years, but the hybrid argument really makes sense. the idea estimates that hybrids would be the next leap, navigation of the 20 thirty's, with new designs replacing the tubing wing. and this will contribute to a 40 percent reduction in emissions by 2050 long flights and most likely use bios deals with some parts of the teen electric side and some use of hydrogen. the petition is a small step, but it gives hold for the potential of the diversity of technologies that we're going to need for the 0 to the plan and the 2 to those plans. like that's the comments section below, come back. every fridays, the machine they go, we often contel, but you little bit suspicious. is nato the strongest defense alliance in the world?

the global self have lost confidence in organization. is the 3 w said light on the reasons behind this would be the not group. how did we get here? know, so next on t w, the down thing, despite the 16 year old and you know, aspires to become stop, to live his dream. he sees his native ukraine. germany, can you just keep around on an international body competition, puts his skills to the test. in 45 minutes on d w, the

you can draw the line between the space is because i don't believe that space is, is i'm all really relevant criteria. and any more than i believe that rice or sex is on frontier in. 2 2 2 2 we humans are closer to a chimpanzee and vanishing. pansy is even to a dog a dr. series about our work. i'm sex with animals watch now on youtube dw documentary. 7 daniel's engine, you belong to the 77 percent to come to i don't good, i'm 65 total was while your top 5 years, 3 reasons why 1115. we are here to help you make up your mind. we are here on please find your mind. so all of the topics i'm much up to you from trouble

fixed a new culture. and then 15 minutes, let's say about community life on the research is now on the top. the nature of cult itself, the strongest defense alliance in the world and the community of values multiple conflict, but to prevent the conference. but this view is not shared by actually want you don't have a protein rights to be in charge. in many countries it's enough for kind of asia. the military alliance is regarded with skepticism and distrust we often call and tell, but you're a little bit suspicious that we are being set up for the future.
