hatred of the people, the exclaimed, oh, hold on, go. the history of anti semitism is a history of stigmatization and exclusion of religious and political power struggles. it's a history of slender, of hatred and violence, or even 77 years after the holocaust hatred towards jews is still pervasive. oh history that you semitism this week on d w ah ah ah ah ah ah, if you live in the countryside, you are surely familiar with the smell of fresh air. the sight of

a clear blue sky and the feel of wide open space. it's simply gorgeous, and it may makes you wonder why anyone would choose to move to a city. but the fact is, 3 quarters of the world's population now live in town. so cities that is over 5000000000 people. and as these areas grow, so do the problems from traffic congestion to storing energy demands. what we need are urban visions, our topic to day on may to welcome. now did you know that one in 8 people not only live in a city, but in a mega city sharing limited space with millions of other inhabitants? and now imagine those millions on their way to work. not sure if the term rush hour still applies. in order to ensure people can actually move from one part of a city to another, new mobility concepts on need it. and sooner rather than later mushrooming

mega cities are a global phenomenon. there are now 3 times as many urban areas with $10000000.00 plus residents as just a few decades ago. but as cities grow, so do their problems. stretches, inched cities or microcosms of society. we can observe all the opportunities and challenges in a very small space, sort of like under a looking glass of you want an implant glass. the income the biggest conservation on the planet is greater tokyo population. 38000000, followed by jakarta with around 34000000 daily mon, by manila and shanghai are each home to more than 20000000 people. as are the biggest metropolis is in latin america, south palo, and mexico city. traffic is a major problem in mega cities. but there are new ideas out there on how to tackle

it globally. hm. we're also used to cars that we can't imagine cities without them anymore. but if we were to experience that, we wouldn't want to go back to cars method an auto silicon. this is how cities might look in future if different kinds of road uses were separated. one road is for fast moving electric vehicles, another for pedestrian, cyclist and scooters. with the 3rd, a promenade reserved for pedestrian, those will be self driving and run on electric power or hydrogen. the many city itself will be powered by solar and geothermal energy, with everything coordinated centrally. by a i, technology. it's been designed for a population of 2000 people who clued as like when it smarter ideas about how people can move around, then be a nash. that's been a city with 5000000 residents and 3000000 cars that are idle, 90 percent of the time. you just need to do the mass and i sent off gobber. and so

that we could probably reduce the number of cars by 80 percent young aunt ben gunn, with a smart sharing system. people could still enjoy the same level of mobility for the answer. the mention of, i meanwhile, at the other end of asia in saudi arabia, there are plans for a new megalopolis, ne um, a linear city comprising for urban hubs. the pet project of the saudi crown prince is set to cost an estimated 500000000000 euros road and high speed rail. transportation are all electric and under ground, neon, nicknamed the line because it's meant to be 170 kilometers in length. is designed to be carbon neutral with a 5 g network driving all manner of applications. as yet. right now, it's a thinly populated and undeveloped area on here. we want to create sustainable infrastructures and stimulate economic activity on the right,

which will in turn create new kinds of jobs and economic development in saudi arabia. ready the country is seeking alternatives to its oil based economy. neon should also boost tourism and attract start up st. media production companies . the entire city's energy requirements are to be supplied from renewable sources. here we have a huge amount of sunlight and ideal wind conditions. so our energy system will run exclusively on primary energy on this energy will and also be used for desalination is energy, but back us water is a big problem here. i was bring me on is an acronym for new future. the plan is to create a city for 1000000 people in just 10 years. but is that really feasible? is love of indiana combined them if the 2 projects have something in the well, it's that they're not what was originally hoped for blueprints and reality

a miles apart. 8 the project assume a managerial perspective, which ignores the fact that cities are more than just infrastructure. what draws people to living there is not something you can plan just like that on the floor plan because woven city and me arm 2 visions of eco friendly, high tech cities where people can actually enjoy life. but will they actually get off the ground? well, all i know is that compared to cities like tokyo or mexico city, berlin is a village and it does have lots of parks and green spaces like tree light, boulevards. but the streets are getting busier. traffic is getting worse. it's not just cars, delivery bands and buses, and of course more and more people are riding bicycles and as often not enough room for everyone thinks must change. and that's why city planners are joining forces

with start up to come up with new and sustainable concepts. who owns the city streets of berlin are increasingly busy with calls, cyclists, pedestrians. all the c color gets around by bike newton. i not so little newton loudon graham and i don't want to live in noisy, polluted concrete jungles with i. i want to live in a city where people, chad on the pavement in common, don't have to shout at one another over the roar of portions whizzing past to puerto. kn beautiful by it. oh, the platform fix, my balin was set up a year ago for the city cycling community. it allows he uses to see, for example, where there's a new psychopath or where a new one is planned. it already has over 1500 uses. the idea is to put pressure on

up and planning authorities. if a bite on klondike mash gonna cv authorities or planning a new bicycle boulevard, or new bike ranch on the public and see whether they approved the plans in northern michigan. okay, back to so you can see what's possible, what the public sees as a priority and what it sees as the less urgent hyphen botany, where there is less demand. if it had been a drop it off, auto. felons population increases by about $20000.00 a year. according to forecasts, the city will be home to some 4000000 people by 2030. how can traffic be reduced? how can traffic flow be diverted to reduce congestion and pollution? these are questions that a group of scientists are seeking to answer with the help of data collected by traffic commerce plume. if my own building knows biospine, let's take a busy berlin street as an example at a street,

you'd think it would be quite dangerous. a cyclist to detect orleans, but besides, if you're ha, we'd look at their trajectories. invoicing, see if they often need to overtake trucks and buses, say a and see if that could be quite high risk of symptom competency. i, ah, the findings could be used by urban planners to redesign busy crossroads. for example. traffic patterns are constantly in flux. recent months have seen a 25 percent rise in cyclists on berlin streets. when the pandemic hit, the city created a number of pop up cycle parts, but the fix, my berlin team says there's still a lot of work to be done. and i to unsticking british merriman, the non stackable compared to other cities or the mayor of the student government and aren't very invested in cycling policy medical em than at one in paris and london. it's a political priority, long, etc. water or hot truck here for chefs healthcare cloud. perhaps not yet,

but the vision reason, city lab a working hard to get berlin up to speed. and yet green smart with pop up a bicycle pass. it's going in the right direction. but the future of mobility will still include cars, and while many consider e cars or electric cars, a sustainable alternative to gasoline and diesel power transportation. it's not that straight forward is a look at some of the issues. electric cars, like me, are still quite a rare sight. there's only $17000000.00 of us worldwide. that's just a tiny fraction of the estimated $1400000000.00 cars in total. but our numbers are growing. e cars use raw materials, mind in south america, the democratic republic of congo and china. these include lithium,

cobalt and rare earths needed in our batteries. admittedly extracting and transporting these materials is an environmental nightmare, often carried out under in humane conditions. but their reserves are abundant. studies show that world wide deposits of these materials could meet demand for years to come. one good thing about us e cars is that we don't emit greenhouse gases, although manufacturing us certainly does. all my components still have to be produced, but my power train only has $200.00 parts, as opposed to a combustion engines. 1400. where my electricity comes from is another huge issue, renewable sources or fossil fuels. the good news is that the share of green energy is growing, which definitely please, in my favor, as battery technology improves, the range of e cars is increasing. right now, it's rarely more than 500 kilometers and often weigh less. finding

a tracking station can also be an issue as to our batteries, 95 percent of them could be recycled in an environmentally friendly way, but it's still not economically viable. but i recommend you sit back and relax. it's surely only a matter of time to day electric cars cost more than conventional models. but that gap is closing the day of climate friendly, affordable electric cars, maybe about to dawn. so whether electric, gas or diesel far too often cars and ob, stuck in traffic jams. but why? because who health there are simply too many cars on the roads. but to we can look to mother nature to find a perfect example of how to keep traffic running smoothly. and i'm talking about

ants. and when it comes to regulating traffic, they seem to have it figured out. there are no jumps on their motor ways. bad traffic, bad vibes and highways are also super busy, but clearly run a lot more smoothly. in the human world, congestion on the roads is a normal part of life. we even keep track of record breaking jams. when hurricane rita hit the southern united states in september 2005, 2 and a half 1000000 people fled houston or tried to the resulting tailback on interstate $45.00, heading inland towards dallas, reached a length of 160 kilometers for 48 hours in the run up to the 2014 world cup and brazil, the roads in and around sell. paolo will gridlocked,

340 kilometers of stationary traffic, almost equivalent to the distance from sao paolo to rio. moscow, november 2012. the notorious russian winter paralyzed much of the biggest country on the planet. for 3 days and 3 nights, snow storms blocked the highway between saint petersburg and the capital. but how do traffic jams actually come about it? the main reason is that you do not have enough capacity. um, of course there are other reasons um, but these reasons, reasons are not that they do not happen that often. um, dumb people sometimes make driving mistakes. of course, for instance, they do not pay enough attention, then they have to break heart rate heavy weather conditions. know that the percent reach

you to look at the same time and the same news in the same direction. but the world runs differently when i met with the principal is one for all and all for one not hardly applies to motorists on the road. everyone's thinking, what's the quickest way of getting to my destination? individuals focus on themselves and don't care about the others. the drivers have a lot to learn from, and i know it on the order of a driver. so they're waiting, and that is a thing which hinder it to be effective. so

that we have different method, good maxima, if you use optimum and a system of dim and nominated for the duration of the user, but didn't look for the lanes. so and cooperate and have a common goal. humans on the road do 2 in a way they each want to get from 8 to be. but the lack of cooperation results in countless people wasting vast amounts of time in traffic jams. how much time precisely telemetry experts have the figures take, for example, germany's biggest city think tom tom has made this kind of statistics and they they have a number of days. how much more time have you invest on your daily commute and for role in this number is about 30 percent in other cities, it's much,

much worse. 3rd spot goes to book, go to the residence of the colombian capital, spend an average of 230 hours a year, going nowhere fast. that's almost 10 full days. the frustration can sometimes boil over ah, number to bring in 29. g drivers in the indian mega city spent an average of 243 hours stuck in traffic. ah, but when it come to rose beating congestion look no further than manila researchers worked out that in 2019 rude users in the capital of the philippines. last 257 hours of their lives to the dean commute to many self absorbed drivers with big egos crammed into narrow, spacious, anti waste by contrast are always busy,

but never congested. how did they manage that? all medical and answer communicate via sense. they have plans to produce them various pheromones, convey information such as danger, food, all this way. he has a community, they want to have the system up to that one through a working on a flow which is not stopped by individuals. so we can run from the and i don't think that's going to teach the people to be like, oh, aunts depend on a communal effort and adapt as conditions change. humans communicate not so much with each other as against each other. and while costing us precious time that comes at a financial cost as well, if it didn't thank you to make this power. so we have highway and you say you have

to pay for kilometer gen g remain for 3 hours and you can drive only 10 instead of 80. then you can calculate what is the last time for all the drivers there and you end up with it being 510-0000 euro one. check on my cadillac info or germany. for example, if you come up with 862100 1000000000, you rule for year english, 80000000000 euro, we lost just by standing still. and jeff, so he jumps only lose time. ah, so what's left to the lessons? can we learn from an individual unit with a medic sisters that we can copy it? and this is the hope that then at the end we will have

invoking traffic system which has a much larger capacity we have today. oh, insights from ounce might soon be translated into better traffic routing and better attitudes. it's ultimately up to us. we need less ego and more consideration for others. it's better to cruise at a moderate speed, for example, than speed and slam on the breaks. perhaps then we'll be able to see ourselves a lot more time and money and avoid seems like fish. ready and how do we get one h a into a city pox help without a doubt. but to what about those places? we actually spend most of our time in buildings, from offices to homes, shouldn't they to be more equal, friendly and healthy? now our ancestors lift in wouldn't, what's, perhaps it's time for this material to experience

a renaissance. oh, my new stance we put with deal in a forest lake is that i have nothing to do with the story. the story is about construction size, concrete buildings and the hopes and dreams of people living in concrete buildings . ah, maybe it's forest full of deer lay. dreema said there is a connection after all. perhaps that might explain why would is a fashionable construction material. it's those almost 20 percent of new builds in germany are made of wood either there in the north where we're just about anybody who enters a home made of wood is almost always overwhelmed by its quality and atmosphere level. when seen, if you go into a newly built wooden house, you'll feel wonderful from the very 1st moment thanks to the structural design and

the very special atmosphere or one atmosphere. thomas vaskins company is developing what is said to be the tallest wooden apartment building in germany, 29 stories 98 meters high. it's called, well, how and is to go up in berlin? langley, not the cities decided that entire district should be built of wood with new school buildings made of timber. and there is some justification for that. we have to aims . we climate neutral in our cities, trees of bound c o 2 for centuries. and when that timber is used for building it remains bound. well, that's the key difference between wood on concrete slabs off, baton and concrete is getting a lot of bad press. nowadays. a key ingredient is cement and according to the u. n's intergovernmental panel on climate change. the cement industry accounted for 3

times more, c, o, 2 emissions than commerce, full ebby ation in 2019. another un reports as construction and building usage. other source of 38 percent of global c. o. 2 emissions concrete is the default construction material, at least for large scale projects. an entire new concrete corta is going up in a district of berlin. only one building currently under construction will be mostly made of wood. only its foundations and staircases will be made of concrete architect, sorry to robbie, has been working with wood for well over a decade with indefinite if you would definitely pioneers. and as such, we've also suffered. we had to overcome many obstacles. met with a lot of resistance from the authorities. we are to assemble a team of experts and of course, convince our client's property owners to begin with. it was anything but easy. i am

far, biden 48 in berlin as a recent project of his. the 6 story cow up with about 40 apartments is almost entirely made of wood and a finalist for the 2021 german sustainability award for architecture. labor all had to be honest, our practice didn't originally warm to would for ecological reasons. that was 2007 i'd started thinking about would perhaps 2 years earlier for its aesthetic aspects aspect is funded by buffoon. i just found it beautiful. oh, it was only later that i learned how eco friendly it is, and that it binds large amounts of c, o 2 is r as mary arrow, the not all forgotten the whoa, whoa, high rise is not just meant to be eco friendly, but also an exercise in inclusivity and social cohesion, it won't be condos for the rich, but rather housing for people of all income levels. as is, yeah, it's about living in a neighborhood in a community. if you live in

a project like this, you have to have the right attitude to wood as well because it lives and moves and creeks. man, you have to be able to and want to deal with that avoid. ah, but to build with timber, you have to cut down trees. how eco friendly is that? we certainly shouldn't just chopped down entire forest, so they're gone forever. well, we need to use the resources we have in germany and central europe, and fell trees selectively. importing timber from further afield would be less sustainable. on suspension. construction him get started at the warehouse site in downtown berlin. but if all goes to plan, the wooden skyscrapers should be standing by 2020. ah! and i was the final urban vision from us city dwellers on this edition of made for
