and so in the clouds it, it's time to us and then when generations flash starts january 14th on d, w. the did you know that dancing and a club can have real monetary value? not just from admission sales and expensive drinks. a club has massive energy costs to carry on a weekend. it consumes as much energy as a single household in a year. but it can also when back these costs with every step you take out, will show you in a moment the . 6 3 sun wind. 3 and water are considered the most important sources of

renewable energy. and what does dancing have to do with it? movement generates kinetic energy, which can be converted into electricity with the help of smart floors in places like clubs, concerts for when walking on city sidewalks of london based startup has developed the floor that converts the weight of our steps into energy and each step generates between $2.00 and $5.00 joules of energy. that doesn't sound like much, but it can add up such a floor. it could be installed in shopping malls or train stations where hundreds of thousands of people walk every day. but it's about more than just electricity. we made energy fun and we now realize that educating people about sustainability and energy and having people involved in the climate change journey of big corporations. and some important to us of us. you know,

i understand that. and once they've definitely creating you missed the feeling that you're participating. big about, you're making a difference by jumping on the floor of a concert home or dancing and producing energy to, to the or the, or you walk through the city making energy through that. and when you see at the end of the street, you have now produce one kilowatt hour. then you suddenly realize that you can make a difference from this office to being, i think that's the important thing, right? power. let's try that. something similar, earlier this year in a subway station, 130000 passengers generated energy for 2 days. the turn styles at the entrance and exit were coupled with a turbine. moving the turn styles generated $2200.00 watts per day. and that's enough for a 4 person household for 9 hours. and it works in different combinations, either via phone of all tech systems or movements you move much all the for honest . it doesn't generate a huge amount of energy. or that's me,

that's for sure. and no, it won't really show that big an impact on the system overall was fine. with photo voltage systems, the solar panels don't always have to be large. some companies now offer ones that even function as roof chiles. entire roofs could be covered with them in the future . in photo voltaic systems will not have to be installed on the roof. they will be the roof. it started from the design point to feel that it looks good and it's so if i didn't draw up a little thing solution at the moment to be on yours to this very lots and function, solar panels. but now we see that actually more and more also this building integrated solutions. ok, i think kind of more feasible engine deed the solar panels are almost invisible.

if that doesn't work, there's still another option. 3800. hamsters can also generate enough electricity for a 4 person household. also in the show, macro bubbles against micro plastics. x x l trucks and a copper mine and the competition for apprenticeships. the more and more microscopic plastic particles are floating and are rivers, lakes, and oceans. the result often of carelessly discarded bottles and plastic bags, according to the world conservation union. $3200000.00 tons of micro plastics enter the environment each year, almost half of which end up in the oceans. a huge problem for which a company is now developing a tiny solution. the world has

a problem, tiny plastic particles, or how spend it in waters everywhere, the harmful to both nature and humans. but a solution has recently been found. tiny bubbles can force the micro class sticks to the surface where they can easily be discarded. isn't really that simple. how soon can this be implemented? hold on time on came up with the idea. he's an engineer and entrepreneur and a successful visionary, for how many people blossom oppressors leaning wastewater with micro bubbles as a new ones learned at a lecture in london. that micro plastics are hydrophobic. they don't like water and will adhere, taken care of bubbles in the water, and the flaws in by size. so for a lot of products have some javascript years later dealings. i'm just the idea of mature. just i'm, i was watching my vacuum cleaner robot and move throughout my study. when i thought of a way to crate and here is technology for the water,

just as the tunnel mostly flowed freely in the water, well cleaning it by salt alone specified small beginnings and the lamps. the challenge was to create bubbles sooner than a hair. so that is many plastic particles that's possible here to them the then the project group, the 1st prototype was called the one which worked on a pond. it was the 1st $0.06 for dumb on his team. this is how the technology works under water bottles, escape at a depth of 2 meters. $2000000.00 per liter, plastic and water repel each other, similar to oil and water. it's different with air which does tend to attract the plastic particles. that's why they adhere to the bubbles, they literally stick to them and thus migrate to the surface. the

a lot of different kinds of i had here in technology can be used wherever micro plastic hotspots arise or are found in on the we've already been able to remove 98 percent of micro plastic components from water in the visa river. in preliminary model tests, not leaving any residue. and we did it without chemicals, just with pure micro level technology, just with their exclusive images, that the 1st large scale plants on land, not using the same technology. the bubbles do a lot, but much energy is required. another problem is that even the tiniest organisms, such as plankton, could reach the surface with the bubbles and likely be removed as a food source from your water. that's why the innovation must be used selectively, where a lot of micro plastic cumulate ideally and heavily polluted rivers such as in asia before the plastic reaches the ocean from sprints from their

a lot of guns. and we still have plenty of challenges ahead of us just especially finding the micro plastics and their respective bodies of water. and that's really hard in the right now, we can remove the needle from the haystack is gone, but we still have to find all of the haystacks and i mostly my offer and found about them as me. how often the technology should be marketable in 2026, to ensure the money does not run out by then the german government has taken over the financing. we come in contact with copper every day. it conducts electricity very well and is a component of nearly every electronic device because it does not run. it is also used for water pipes for brewing beer for, for making cheese. the stature of liberty in new york is made of copper, and so is an entire subway station in paris. copper is mind in huge open tasks, mines with enormous excavators and trucks. a case for our ex ex l

series, where business gets big. she drives one of the biggest trucks in the world, caterpillars 795 half here in europe such as copper mines run by the company. both of the vehicle is as big as a house. 8 meters tall tag along with her to load up some rocks. sophie visited them, drives through the page in this 3400 horsepower vehicle. so how does one actually get a driver's license for one of these massive trucks? you have to be uh, at least 21 years old. your drivers license for a car for 3 years and then the education like this, both of the well i will say to i sometimes,

i mean shift is 8 hours to pass down into the mine is steve tied here. so we have to waving is required. so that other drivers can see that your away can doing fine. the truck transport $600.00 tons of rock per trip and breaking times are long. i think maybe i don't know with reaction time rates time are because this is a big truck and it depends on how we load the road. if it's no way it is said to be loaded. now the world's largest excavator vehicle gets into position the p. n. h excavator, 4100. c 10. 1 load carry 60 to 80 tons of rock. it has 2 motors

and can even be operated electrically. massive explosions are a common place occurrence here. every months, new layers of stone are being loose and for transport. the curvy route state used to be there, i'm no longer exist. and that even gets on sophie's nerves. sometimes when you are free for we do come back to you. it's not sure that you will find your way around here because it always, always change under your belt stretch for miles, transporting the proper rich rock to the stone mill. it's also the world's largest of its kind. they use the same amount of energy as some cities. it makes me feel very small. the rock is put in water basins,

where it is chemically processed to separate the cover from other substances. in the end, you're left with this concentrated copper mixture engineer monkey selina works in the preparation hall and is one of the people in charge of the refining process to add another factory cover is separated from the mixture and melted down apart from small amounts of silver and gold, more than 99 percent of the production consists of copper to factories consume massive amounts of energy. plus the electricity they're using comes from 100 percent renewable sources,

such as from this nearby hydro electric plant. that has improved the minds, carbon footprint in the past years, and that's important to the industries customers the customer, the demand, uh i will say a cup, the product, the test has low call them footprint and also good quality if they are fortunate to have mainly high on the hydro power elections to hear sophie under colleagues driving 3 shift, gee and tonight, all year round, over half of the 60 drivers here are women. this is usually something that people think is a man's job or something that women can do it too. so why would you like me? oh, i think it's attractive because it's fun. now it's time to fill up the fuel tank with overs 7000 liters of diesel. it's as much as the heating oil needed by one

house over a year. the truck can go for 32 hours per tank load, then it's also set to change less diesel and more renewables are truck isn't electric hybrid with one diesel engine and one electric motor. the. so now we're going to connect to the trucks, drive on renewable energy coming from the electric cables above them, the by 2030. all the trucks in service will be electric, then the company will marketed as green. copper virtually c o. 2 free and powered by 100 percent renewables. yet

diesel engines and trucks. excavators and agricultural machinery still bother us. and diesel means exhaust fumes set. and c o 2 emissions. electric motors like those in cars are not an alternative. the longer the distance and the heavier the vehicle, the less likely it is that a battery will suffice. could hydrogen be the solution? the, the global population is growing. more and more energy and resources are needed. goods are being transported around the world, resulting and for higher levels of c o 2 emissions. transportation needs to become climate neutral. could hydrogen engines be the solution for a long whole vehicle? the a, b. c, the advantages of

a hydrogen combustion engine. when it comes to heavy duty vehicles on the high load vehicles all and high durability vehicles, internal combustion engines are durable and can deliver millions of kilometers in performance. what it's actually very simple. you can, we fit a classic diesel combustion engine there by turning it into a hydrogen engine that's completely climate neutral. and that way, all diesel engines get refitted instead of being chunked, the piston, some other components need to be modified. automotive suppliers, mike mullins, are adapting and producing the components for the new hydrogen engines. demand from engine builders is hi, this is an come off list of you're using this 7.88 or diesel engine that we've said with hydrogen components instead of covenant and fuzzy and how we lift everything

the way it was. because the engine is a good starting point, that's why we chose it and just added the hydrogen component of components to the boat. we convert basic diesel engines into hydrogen and jobs all about that stuff most all inside your and also has a very low ignition temperature, which means you need very little energy to ignite it. that's why we need to install an ample amount of control technology. the engine is being stress tested using the continuous load. it's scheduled to go into series production by 2024. at 1st, they'll be used to power generators for construction sites and hospitals. demand for hydrogen will continue to rise for commercial and private vehicles to the german national hydrogen council. estimates that demand for hydrogen fuel is expected to increase by more than 8 phone by 2015 by source tough hudson to lease.

if you want to have hydrogen on the road, then you have to fulfill certain requirements involved in those like building filling stations successfully enough vehicles would have to use them for the stations to be economically viable. so $400.00 cars would be needed is that would be difficult because there are only a few hydrogen cars around i was, but a fleet of 20 trucks and wouldn't be enough to make it economically viable, especially for commercial and fleet transport bias. because under the union, in front of the price of hydrogen at filling stations is still relatively high. but once the infrastructure is in place, the prices should go down. a car, for example, needs one kilo of hydrogen per 100 kilometers. and 12 years time, the price of hydrogen is expected to go down by more than half from 14 year olds to just over 6 engine manufacturer, doyle develops and produces engines for commercial vehicles. hydrogen propulsion

has many advantages for tractors, agricultural vehicles, and trains. then i'm on the vehicle with the machine, you have a very large machine that has c 300 horsepower and it's run with a heavy load for a long time when it needs a loss of power. the machine no such as with excavators, whitestone, then you need so much energy, the bonds where they would come to getting bigger and bigger. a mistake you bought the year even with an excavator at some point, that is hard to build that big enough back to the think about that even type of thing. it's a necessary infrastructure is built, then hydrogen engines could help to create a more climate friendly future. we need skilled workers in germany, half a 1000000 in fact, and the energy and electronic sectors. b, i t industry and or secretary and in the construction industry. but germany is

losing its attractiveness and international comparison that is about to change. how much immigration does germany? in 202281 1000000 people worldwide, no longer lived in the country of their birth. that's 3 times as many as in 1970. according to statistics, the most popular destination for migrants is the u. s. followed by germany and saudi arabia, the although jeremy has been recruiting foreign workers since the 19 sixty's long could not see itself as a country of immigration. but gosh, tina australia, brazil, the us or canada, the guest workers from italy, turkey and portugal worked in germany to help it of cheap economic recovery. later they were supposed to leave, but they didn't. today,

many economists in germany are calling for regular immigration because of demographic change. too many people are retiring well to a few young people are entering the job market. there's a shortage of skilled workers everywhere. according to economist, monica schnitzer, germany needs 1500000 immigrants every year. after deducting those who leave $400000.00 additional people would remain each year. that would be enough to keep the german workforce going. but immigrants still often face hurdles and of lack of acceptance. the canada has long shown how things can be done better. they are new citizens are invited to an official naturalization ceremony. but before that, the migraines have to qualify in a point system which evaluates education skills, language ability, and work experience. with this skills, immigration act,

the german government wants to encourage the immigration of skilled workers from non e u countries. but it takes more than a law to bring immigrants to a country migrant must feel accepted if they are to stay the and now the sky is the limit. have you ever plunged from great heights with a parachute or a bungee cord? then you probably shouldn't be afraid of heights. it's also applied to professions and high res construction or roofing. a roofing company in germany wants to find out which train you ship. applicants are suitable with a composition the 30 meters size in a swinging basket. it's a test, every applicant has to pass and it's part of the training each challenge. berlin,

roofing company or a 12 candidates. but only half of them get an apprenticeship fund. everyone's nicholas siegler is one of them. he left college before finishing his business degree. and now once a job in the cities rooftops else just decided to view um, freedom detachment from the ground. just a little more clarity in that cloud as easily hooley also wants to start an apprenticeship to finally learn a trade. no more odd jobs like before. so this stuff, okay, now logistics, restaurant work, waiter logistics, dishwasher work in clubs, a cemetery gardener to scout nod and that's inclusion. now is it just has to go up on the crane and prove that he can work a lot of good. i'm nervous, but in good spirits, it's all secured because of this off cuz it's of nicholas tries is handed welding

the is miss. it's not that easy as you can see here though, because it's also relatively hot open, but it's interesting. i've never done it before. i was little for i don't even look as easy as back. no fear of heights. 30 meters in the air is no problem for him. he didn't even need to hold onto the railing. he did a great job next. nicholas has to build a roof trust with a partner. this is where team spirit is tested. talking about and tell you that those 2 could definitely do something in the trades turn most eyes them on a roof or has to be able to solder for these. it's a bit difficult, but he won't be discouraged. smells people hero doors, but they don't talk much and that's how i wanted to lose all sense. now, the moment of truth, the staff come together in the workshop and discuss who they want to take on. everyone has a se patient is that good?

i think it's great. yeah, cuz it's journeyman. we also get to decide who we want to train, who we want to work closely with. and when we get along with the some kind of the month back on the i'm looking to wait for the results, then the winners are announced as easy as one of them. nicholas can also start his roofer apprenticeship. off info. see i'm so i can just relax a bit and look forward to finally getting started before the industry stuff and so got submitted for me. it's a nice alternative now that i'm no longer in college to come to a new apprentices. we'll do a 2 week internship before they sign their contracts. the company wants to be absolutely sure that this is the right thing for them. that's set for today's episode of made the double use business magazine your next week. and if you can handle, it's maybe

a better stay on the ground until then the

she is a monster of big lots of confrontation. this is your vision of that will come back to me and you're going to apply the undisputed champion, tell physical to the trying to frighten people. so it's a fight. everybody understands it, except you enter the conflict zone and joined him. sebastian as a whole, the powerful to account. this is a big fan you, whichever way you like to spin conflict the news. 30 minutes on the w. a religious community refuses to be swept up by natasha in the house of america. this is,

this essentially is hold nice thing of the young people face the time of exploration and decision making. will they embrace the heritage step into the model? so the only thing 75 minutes on the double the books people have to say the that's why we listen to based on the ritual to every weekend on d w, you'll see about the video that goes enabled other data media may google,

google. i've got that done by get other stuff into that and i'll give you go on, would you? are you able to go to that? i'm jo made any a dog coloring key, more people than the eval on world wide in search of a job. you ever use men and they can t method the how do you find out about on the story, inform icons cost about why does that mean? because like now i'm leave them on the, the new host to join us for an exciting exploration of everything in between. this is a video and audio production 5 d, w. i hope that you will tune in the,
