messages are so pretty like wild fire and thousands of followers are. on the streets and. they don't seem in the morning getting to. you to. start point you want to be w. . you ever feel like the walls are closing in if you live in the city they literally might be around the globe more people than ever before are flocking to urban centers where already limited space is getting tighter and more expensive megacities are bursting at the seams and so is the infrastructure that keeps them taking landfills pile up higher and higher traffic jams get longer and longer

there's an economic poles in the city where the majority of global growth comes from megacities mighty and monstrous that's our topic today on made thanks for joining us so with all these people go shoe box sized studio in hong kong sleeper van in san francisco if you view an apartment here in berlin expect hundreds of other applicants to show up as well so where does the city planner turn when affordable space grows tight that idea was already being tackled one hundred years ago by german architect named walter gropius the founder of the bauhaus and the figures in the movement with him wanted to build apartments that were beautiful functional and affordable more than design and form the house was a show a social revolution that has had an enduring impact. want urban high things look like in the future. good spend. good light

supply is tight and prices are soaring i foresee colorful cities but dense and high rise. urban design needs to be reinvented. systematically question every time. designing affordable apartments is a new venture for architect hart building a complex of one hundred forty units in the german city of. good living space and attractive architecture for citizens with low incomes it was commissioned by the local authorities. until now designing single family homes for the wealthy has been his speciality this is a new challenge clarity of line and form rectilinear a minimalist aesthetic balance work has been inspired by the bauhaus.

gendered and entirely new movement that's as relevant as ever to this day. what inspires us most is the clarity and the holistic approach of the bauhaus. a group of people came together to create something new in their teaching and in their practice ranging from skyscrapers to products to graphics every area of design and all that for the benefit of ordinary people. runs in their subsidized housing project will be six euros fifty per square meter very moderate nowadays in a city like. but it's not only about being cheap. everybody has the right to good architecture and good design. germany lacks affordable housing experts estimate it would take well over a million units to meet demand and can. struction has lagged way behind rents are

high and rising in cities like munich. there was an acute housing shortage a century ago as well with math of overcrowding and terrible sanitary conditions in gloomy tenements as here in berlin poor people often also worked in the spaces where they lived. the bauhaus movement was founded in one thousand nine hundred nineteen and soon came to champion a vision of society and design that was radically new even revolutionary it wanted to create good has thing for everybody. to achieve that goal that develops standardised units and industrialized production to bring down costs about how it was at the forefront of modernist architecture championed simple forms free of ornament large windows and light colors. it also pioneered prefabrication at the time it was simply not technically feasible

to put together entire modules as opposed to manufacturing single component. but that changed. the course for a company makes much for the construction industry. at its factory in holland for example it makes sixteen prefab units a day including flooring and windows. they'll be put together on site to make say a kindergarten school or hospital this kind of construction can prove much faster than building in conventional ways. this is a standard complaint used to be that this is somehow inferior to simple architectural inflexible but that really doesn't apply any longer we can do anything that conventional construction can do apart from circular but at a push we could do that to. for local

authorities to create affordable housing construction costs have to be kept low. when an apartment in this complex in munich goes on the market has one hundred people apply the rent is ten heroes a month per square meter that's cheap for the city. the complex was designed by these three architects for munich's municipal housing department as homes for people with average incomes their remit to build good has ing as cheaply as possible. the demand for accommodation is rising as job growth in the city continues. to market of hidden fire we're going to have to reflect on our expectations and requirements. how can we create high quality small apartments. and how small is small. this doesn't mean doing without generous bases we just have to minimize a little and get

a little cleverer in design. unadorned. standard windows the same layouts on each floor simplicity is key that something that our house taught us well. but the comfort of those who live there also plays a central role in designing and improve our lives and laid out well. for the challenges that space is limited and things are getting more expensive including brands. so we have to respond by using this space still available to us for affordable housing. because one of. us is indeed at tall order a major challenge for housing authorities urban planners and architects buildings that are cheap and actually nice to live in.

but every year some forty thousand people move here through the german capital of berlin and up with pressure on the job and real estate markets and places new stress on infrastructure like public transportation water or gas at the moment berlin has just over three point five million inhabitants it's just a tenth the size of one of the world's biggest cities tokyo the pressure on megacities like these are immense but so are the opportunities so how can it all be managed one answer could come from the growing data streams around us. big cities are more popular than ever they can be a modern habitat and a motor for economic growth fifty five percent of the world's population already lives in cities by two thousand and fifty that's expected to rise to seventy percent. more and more people are moving to the world's megacities megacities or urban centers with more than ten million residents back in one nine hundred fifty the only megacities were new york and tokyo today there are thirty three of them.

megacities promise access to well paying jobs modern health care schools and universities. urbanization is stagnating in europe the world's biggest and most densely populated cities are in asia. but the fastest growth in urban populations is forecast for africa. an example of explosive urbanization is lagos' in nigeria one of the fastest growing cities in the world. and here the problems of rapid growth are impossible to oversee living space in crowded urban centers become scarce hence expensive worldwide twenty five percent of city dwellers already live in informal settlements or slums. these neighborhoods often have unreliable or nonexistent supplies of drinking water or electricity another problem inadequate waste disposal and sewage systems and roads and

transportation systems in fast growing cities are chronically congested. infrastructure just can't keep pace with the growth of megacities. city planners want to solve these problems with the help of electric vehicles and renewable power sources they hope to make cities smarter and better networked by collecting more data about the residents. when do they travel to work when does the garbage get put out when do parking spaces free up. it all has to become more efficient. and urban agriculture can move food production into cities as well but what happens to the countryside will entire regions soon be devoted to the inhabitants neglected. maybe that's a good thing finally an opportunity for nature to recover.

those megacities grow they create mega amounts of trash and it can't just be pushed the immediate outskirts of the city because it is everywhere expanding all the time the world already produces over a billion tons of garbage a year and that's projected to double in the next ten years so what happens when more waste is concentrated within a city perimeter my colleague ben physical and took a look at how a very prominent corner of berlin is dealing with just this challenge. roseann prosperity can have a certain smell about them. the make in cities of the future will have to manage waste differently unless they want peace on their doorsteps. but then found a solution a long time ago i bought some of plots one of the city's main causes. it's been to a large europe's busiest intersection the berlin wall country into then europe's

biggest construction site the perfect opportunity to dig deep. this is where the wall used to split east from west nowadays thanks to the waste management firm alba it's all about up stairs where life goes on and downstairs where the dirty work happens i'm here to meet the lord of the underworld. he will shortz first i've got to find him. it's a giant leverage down here. sure five kilometers of service tunnels for the offices hotels in theaters about i've never seen anything like it. and seen an unsung heroes for the one hundred thousand daily visitors to put some accounts. out over the lives of youth by stars like lady gaga award ceremonies. what i was looking for actually is. the ice cream that.

he is the guy who helped plan this place a visionary he came up with the concept in the ninety's with no knowledge of in a different i'm sure. he says the set up is one of a kind that would make city small livable. the people seven stories above us produce eight tons of trash a day. separating plastic from organic is still a major challenge for so many people when they throw away their rubbish but the manual task of separating all the gunk from junk is worth it nothing goes to waste these leftovers of pureed the fat siphoned off for using cosmetics the water removed from treatment all that's left a tiny little flakes sent off to a bio gas plant to create energy. six thousand for the dehydration machine saves a six thousand kilometers of unnecessary transportation within berlin every year

instead of fifteen thousand containers we only have to transport five thousand fight in other words we reduce the garbage in our cost by two thirds. and that in a country often stuck in analog. and other details on the days are scanned this is the system knows which ones belong to which customers then they're billed and it's all logged and biggest. then there are others silver bins they detained since it is done have a shredding company secrets that won't see the light of day. what's not a secret is that the global population is booming it could reach ten billion by two thousand and fifty but the projections show the mountains of waste will grow even faster. modern underground ways. management is he solution and in the future robots. taking deliveries and removing waste is tricky we want to

start sending robots through the service tunnels to do the cleaning at night and she can. get a lot of the signals ya know there's a lot of interest from abroad especially from big cities they all take a good look around and want to use this as a model for what they're building this takes the burden off the environment being underground there's no noise pollution in the streets or on clogged life is better above. usual and this it is of the future looks likely just as well to get the digitized underground everything serviced from below and the vibrance of life above . the sea is not the vibrance of life he's talking about but this is the way so many cities operate leaving the rest of the planet to drown in its own waste. and cities grow bigger they also have to grow more efficient and trash collection as we just saw but also on public transport energy delivery water treatment you

name it and that's why more and more urban centers are turning to digital platforms where settings for all of these services can increasingly be tailored to real time data the so-called smart city is more than just a blueprint in taiwan it's already in the works and it's all being powered by electronic currency. cities around the world are growing at an unprecedented pace in asia half a billion people are expected to move from the countryside to the cities over the next few decades my question on a monumental scale and one that involves monumental challenges. has come up with an idea to meet some of the challenges he's the co-founder of the successful cryptocurrency iota sheet or wants to use io technology to let machines in urban areas communicate with each other and turn megacities into smart cities. so the city of the future is obviously fully automated where we have to send

actuators to actually interacting with each other because the biggest problem that we have today is we have all of these different data side us where data is not being exchanged and through that we don't really have a smart environment and a city of the future stephanus smart network right where these different actors and machines and also human start exchanging data with each other and then make decisions based on that data. created in twenty fifteen iota and now has a workforce of ninety people worldwide domenichino has developed algorithms that enable large quantities of data to be processed rapidly the major applications for yoder definite is machine economy right so where for example the car now has a wallet and the car now can start paying smart infrastructure which includes and charging or toll stations or. paying for data buying data from other machines and so on and so forth as one city that is already making use of this technology is

typing in february twenty seventeen iotas signed a partnership agreement with the taiwanese capital. interesting thing about taiwan is that they're very open to new innovations so they also want to provide an environment where you can explore your technology very contested out and so the city came to us and they wanted to partner with us smarts it is of great interest to us because there is true r.t.m. contest different use cases from different sectors where it is energy it's mobility it's supply chain. the we know sharing project is also geared up to this large city it has several thousand electric scooters available across taipei that are reserved and paid for by and the aim is to reduce noise and pollution. the type you thor and he's also have a joint venture with the supermarket chain to improve convenience for food shoppers . support over twenty cashless payment systems the credit cards to. markdowns of course they're open twenty four seven. and in taipei self-service smart technology

has now expanded to include garbage recycling the i trash machines automatically process cans and bottles while issuing credit to the disposer it can be used for a bus or train ticket or further incentive for residents to recycle the future's going to be a condiments where these machines around us make our lives easier and research tells us your neighbors off his future because there's the inherent business model behind it by so i want to pay the machine to do do a certain service for me and this this pain may can only happen through this open network and is open crypto currency right so that the machines can actually accept my currency and i can a pain machine and i can pay them for the service. machines that communicate with each other by the foundation of tomorrow's smart urban centers there are some concerns about the security of the new technologies but there's no question they'll play a major role in the cities of the future. what would modern cities

be without elevators a lot closer to the ground that's for sure but that's not an option for the mega-cities of the future which won't build outs but up german firm to syncrude hopes to be at the forefront of the latest developments by completely rethinking the humble lifts among its developments a mag lev elevator that can go higher than any of its traditional counterparts and move sideways as well sounds pretty cool doesn't it take a look. the way skyscrapers a bill to set to change dramatically to get a sneak preview i went to a new elevator testing tower in southern germany. about two hundred forty six meters it's the tallest in the world. the tao is great news for engineer marcos yet or he can now finally test his state of the art maglev elevators. the idea of developing a cable less elevator has been around for a. century but we are now taking this step and breaking new ground where that other

elevator manufacturers would also be keen to have this kind of system. than down we head in one of four elevators this one works with cables. it feels a little like freefall it takes thirty seconds it could go faster but that has a drawback. we are with the gate meters a second do you feel it in your ears compensating for the air pressure the whole time is there a speed limit. presently there is no limit as such it's more a question of comfort for passengers. no elevators to stand at speeds faster than ten meters per second to know that because it hurts. yes it can hurt so where are the maglev elevators it's community come the store approaching the core of the tower which contains the shafts for testing our new elevators.

they've been twenty years in development unlike conventional models they function without weights or cables. the elevator kavin sits on a kind of slide that travels along to guide rails. the rails essentially do the same thing a cable does in conventional lifts the power generates a mobile magnetic field that propels the cabin in the planned direction. the cabin can also travel sideways. what's called the exchanger sets it on the horizontal track. i'm not allowed to take a ride the engineers are still waiting for safety approval that should happen in about two years time. if there's a sudden power outage the brakes immediately grab the guide rails cooking the cabin

in place. the system would open up entirely new possibilities for architects every day in major skyscrapers thousands of people need transport. one idea is to link several skyscrapers together with horizontal elements then passengers will be able to travel in a circle. because they don't require cables or weights maglev elevators can also travel much higher than conventional designs that's why you had turned his team are testing the elevators for use in new buildings and brand new markets. your car the indians i wasn't just using this cable a system we want to go beyond the limits posed by today's conventional elevators we want to go far beyond three hundred or six hundred meters up we're shooting for the thousand meter range of. the test tower built by star architect whole modi'in is really striking the company spent money on it for a reason it's also an elevator showroom for its client. but lots of people want to

visit the viewing platform. tickets cost nine euros two hundred thousand visitors come every year. there are very annoying and can you use them as guinea pigs as if we don't experiment with our visitors and they don't get in the way at all we've managed to combine the functions we've organized that very well with the visitors like those you see here today we can get on with our work just fine with them here. on the way up my stomach drops into my shoes. with the elevators here have special dimensions and weights. the tower was specially built in order to test them. it took ten months to construct the building shell it went up at the rate of several meters a day. it contains a dozen test shots offices and

a visitors platform. the exterior of the tunnel is covered with a translucent textile skin to cut down on the amount of sway when the wind is high . for many visitors just riding the elevator is experience enough but marcus yet it would also like to finally earn money selling the modern elevator systems. it won't be long the first maglev elevator is slated for installation in a skyscraper in berlin in two years' time. as cities grow so will the innovations that make them cleaner more connected and ultimately more livable but will we actually make communities out of these cities or grow more and more anonymous the people who live right next door that's the bigger question so check in on your neighbor once in a while and ask how it's going and that's it for made this week we look forward to seeing you know next time until then take care.
