is $360.00 degrees and explore fascinating. both heritage dw world heritage 360. now the did you know that dancing in 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 . 3 sun wind. 3 and water are considered the most important sources of

renewable energy. and what does dancing have to do with it? mostly 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 start up has developed the floor that converts the weight of our steps into energy and each step generates between $2.00 and $5.00 jewels 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, a big corporation is 7 quotes and suits of a c o. i explained to them once,

they definitely create new you missed the feeling that you're participating. like 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 of this of to being. i think that's the important thing. powers 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 turnstiles 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 much all the for honest. it

doesn't generate a huge amount of energy or just minutes for us 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 to even function as roof trials. 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, going to feel that it's looks good and it's so if i didn't draw up a little pink solution at the moment, re on yours to this very large and function. so our panels. but now we see that actually more and more else with this building integrated solutions. ok, i think kind of more feasible. and indeed 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 competition for apprenticeship. the more and more microscopic plastic particles are floating in our 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 are suspended in water is everywhere, the harmful to both nature and humans. but a solution has recently been found. tiny fumbles can force the micro class sticks to the surface where they can easily be discarded. is it really that simple? how soon can this be implemented? pulled on time on, came up with the idea. he's an engineer and entrepreneur and a successful visionary, perhaps difficult allows leaning wastewater with micro bubbles isn't you know, once learned at a lecture in london that micro plastics are hydrophobic. they don't like water and will adhere to air bubbles in the water, which is on the flaws and so forth unless the sun, java's figures later dealings on is the idea of mature. just i'm so i was watching my vacuum cleaner robot and move throughout my study when i sort of

a way to crate and adherence technology for the water. so what a ton of must be flowed freely in the water or cleaning it by salt alone or specified small beginnings and the lamps. the challenge wants 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 dumped one, which worked on a pond. it was the 1st $0.06 for dummies team. this is how the technology works under water bottles, escape at a depth of 2 meters to 1000000 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. a lot of different

kinds of other hearings technology can be used wherever micro plastic hotspots a rise 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 and preliminary model tests, not leaving any residue of them and we did it without chemicals just with pure micro level technology licenses, just with their exclusive image, is that the 1st large scale plants on land, but 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, disappointing source from your water. that's why the innovation must be used. selective links, we're a lot of micro plastic. the stimulates ideally and heavily polluted rivers such as in asia, before the plastic reaches, the ocean spreads from they see how much are they going?

so we still have plenty of challenges ahead of us just especially finding the micro plastics in the respective bodies of water. that's really hard. indeed. right now we can remove the needle from the haystack is kinda cool, but we still have to find all of the haystacks in almost a mile from and some of them as we have 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 pipe for brewing beer for, for making cheese. the stature of liberty in new york is made of copper. and so it was an entire subway station in paris. copper is mind and huge open tasks, mines with enormous excavators and trucks. the case for our ex ex l

series, where business gets big a. she drives one of the biggest trucks in the world, caterpillars 795 half year in europe such as the copper mines run by the company. both of them 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 drivers 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 all the way over to uh,

sometimes i mean shift is 8 hours the pass down into the mine is steep beside here. so we have to make waving is required so that other drivers can see that you're awake and doing fine. the truck transport $600.00 tons of rock per trip and breaking times are long. i think it maybe with reaction time rates time bars, because this is a big truck and it depends on how we load the roads. how are they? is it snowy? is it 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 it can be operated electric. the massive explosions are a common place occurrence here. every months, new layers of stone are being loose and for transporting the curving routes that 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. it's not showing that you will find your way around here because it always, always change your belt stretch for miles. transporting the copper 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. copper is separated from the mixture and they'll sit 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 minds, carbon footprint in the past years. and that's important to the industry's customers . to the customer, the demand uh i will say a cup, the product that test has low call the footprint and also good quality of the fortunate to have mainly high on the hydro power elections. to have sophie under colleagues driving 3 shift. gee, and tonight, all year round, over half of this 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 was it like oh, i think it's attractive because it's fun. now it's time to fill up the fuel tank with

over $7000.00 leaders 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 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. the excavators and agricultural machinery still bother us. and diesel means exhaust fumes. set m c o 2 emissions, electric motors like those and 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 ever higher levels of c o 2 emissions. transportation needs to become climate neutral. could hydrogen engines be the solution for a long whole vehicle?

we see 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 . you 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 even come up with a new we're using this 7.8 liter diesel engine that we'd fit with hydrogen components instead of an instance of the and how we lift everything the way it was

. because the engine is a good starting point. that's why we chose it. you can just add this a hydrogen component once you've also spoke components. that under both, we convert basic diesel engines into hydrogen and dropped off about that stuff. most all hydrogen 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 full blank 2015 by source. tough hudson.

actually sure. if you want to have hydrogen on the road, then you have to fulfill certain requirements involved in the whole like building filling station successfully enough vehicles would have to use them for the stations to be economically viable companies to move. 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 on the union and from 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 of the village. and i know the eccles unless you not, 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 lot of power. the machine, no such as with excavators, me me to allows them then you need so much energy the box or they would come to getting bigger and bigger. misty bought the year. even with an excavator, at some point that it's hard to build a big enough spot to the think about that even type of thing. it's a necessary infrastructure is built in 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. the i t industry in the care sector and

in the construction industry. but germany is losing its attractiveness and international comparison. that is about to change. how much immigration does germany meet? in 202200. 81000000 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 germany has been recruiting foreign workers since the 19 sixty's big long could not see itself as a country of immigration. like gotcha, tina australia, brazil, the us or canada, the guest workers from italy, turkey and portugal worked in germany to help with a cheap economic recovery. later they were supposed to leave,

but they didn't. today, many economists in germany are calling for regular immigration that because of demographic change, too many people are retiring, while to few young people are entering the job market. there's a shortage of skilled workers everywhere. according to the 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 immigrant still often face hurdles and a 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 pointed system which evaluates education skills, language ability,

and work experience with the school 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. migrants must feel accepted if they are to stay the 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 the competition, 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 they're 12 candidates that only have system 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, i was just cuz i had a view of freedom detachment from the ground, just a little more clarity mccloud 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 scouts. not on this end. please. now is east has to go up on the crane and prove that you can work a lot of good. i'm nervous, but in good spirits, it's all secured because of because it's of nicholas trice,

who's handed welding the english. it's not that easy. as you can see here 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. you 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 a 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. sometimes people hear doors, but they don't talk much and that's how i want to know who's all sense. now, the moment of truth, the staff come together in the workshop and discuss what they want to take on.

everyone has a se patient is edward. 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 close. so the way the thing when we get along with all these in con, would be month comes, the applicants wait for the results, then the winters 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 and for the industry stuff since they've got some issues for me. it's a nice alternative now that i'm no longer in college to come in a new apprentices. we'll do a 2 week internship before they sign their contracts. the company wants to be absolutely sure if 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 high, maybe

a better stay on the ground until then the,
