green lens ice again, this time is research as well as to find out exactly how to think about prices. can you have to listen to reveal its secrets? thoughts, january 12th on d, w. the did you know the damn thing and a club can have real monetary value not just from admission sales and expensive drink. 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 wind back these costs with every step you take out. we'll show you in a moment. the

sun wind. 3 and water are considered the most important sources of renewable energy. and what does dancing have to do with it? moves link generates kinetic energy, which can be converted into electricity with the help of smart floors in places like clubs, concerts, or 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 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 electrician.

it is. 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 has some important to us. you know, i was kind of what they've definitely creating. 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. you, then you suddenly realize that you can make a difference to the being. i think that's the important thing like 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 the 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 and different combinations, either via phone of all tech systems or movements you much all of the for honest, it doesn't generate a huge amount of energy. or that's me, that's for sure. 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, going to feel that it looks good. and it's a venture of the little thing solution at the moment. and we are used to this very

lots and function, so our panels. but now we see that actually more and more also just 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, micro bubbles against micro plastics. execs l trucks and a copper mine and a competition for print to ship. 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 are a huge problem for which a company is now developing a tiny solution. in the world has a problem. tiny plastic particles are suspended 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 discard. it isn't really that simple. how soon can this be implemented? pulled on time on, came up with the idea. he's an engineer, an entrepreneur, and a successful visionary. perhaps maybe people 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 to it and air bubbles in the water and the flaws in by size,

so for unload on go to 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 saw out of a way to crate and adherence technology for the water with 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 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 dummies 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 other hearings technologies can be used where or mike or 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 days of river and 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 the water. that's why the innovation must be used selectively,

where a lot of micro plastic stimulates ideally and heavily polluted rivers, such as in asia, before the plastic reaches the ocean from sprints. from there we have 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, comfortable, but we still have to find all of the haystacks and i mostly my offer. and some of 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 it

was an entire subway station in paris. copper is mind in huge open tasks, mines with enormous excavators and trucks. a cape for our ex ex l series, where business gets big. she drives one of the biggest trucks in the world, a caterpillar $795.00 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 pit in this 3400 horsepower vehicle. so how does one actually get a drivers license for one of these mess of trucks? you have to be uh, at least 21 years old. your drivers license for

a car for 3 years. and then the education lights on default. they need to, uh, sometimes shift is 8 hours the pass down into the mine is steep side here. so we have to make 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 reaction time rates time. far because this is a big truck and it depends 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 easily be operated electrically. massive explosions are a common place occurrence here. every months, new layers of stone are being loose and for transport, the curve routes that used to be them no longer exist. and that even gets on sophie's nerves. sometimes it, when you are free for we do come back to you. it's not sure that you will find your way around here because you 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 are left with this concentrated copper mixture engineer monkey, selena 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 builds it down, apart from small amounts of silver and gold. more than 99 percent of the production

consists of copper 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 plants. that has improved the minds, carbon footprint in the past years. and that's important to the industries customers the to the customer, the demand uh i will say a cup, the product that's as high as low call them footprint and also good quality if they are fortunate to have mainly high on the hydro power election to hear sophie and their colleagues driving 3 shift j 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 was it like

oh, i think it's attractive because it's fun. now it's time to fill up the fuel tanks 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 float, then it's also set to change less diesel and more renewables. 3rd truck is an 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 a 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 and 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 that we see the advantages of a hydrogen combustion engine? when it comes to heavy duty vehicles on the high load vehicles all and high drawer ability 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 off the list of you're using this 7.8 liter diesel engine that we'd fit with hydrogen components. and you said the couple minutes and fuzzy and how we left everything the way it was because the engine, it's a good starting point. that's why we chose that just added the hydrogen component of components that we convert basic diesel engines into hydrogen and dropped off. and all 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 by 2050, by such 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 stations, subtracting 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 and the price of hydrogen and 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 track there's agricultural vehicles and trains then i'm on the vehicle so much, you know, if 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 twice them. then you need so much energy than the box or they would come to getting bigger and bigger. a mistake you bought the yeah. even with an excavator, at some point that it's hard to build a 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, the i t industry and 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? 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 jeremy has been recruiting foreign workers since the 19 sixty's age long could not see itself as a country of immigration. like arch 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 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 up sexual naturalization ceremony. but before that, the migraines up to qualifying a point 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 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 the ship applicants are suitable. with the competition, the 30 meters high

in a swinging basket. it's a chest, every applicant has to pass and it's part of the training each challenge. berlin, roofing company the 3rd 12 candidates. but only half of them get an apprenticeship. the fund everyone's nicholas siggler was one of them. he left college before finishing his business degree. and now once a job on the cities, roof tops house just decided to view um, 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, wait or logistics dishwasher to work in clubs, a cemetery gardener to scale. it's not on. 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 this of nicholas tries is handed welding the business. it's not that easy as you can see here because it's also relatively high . okay, but it's interesting. i've never done it before. i was little for it on the left. 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 the partner. this is where teams here it 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 want to go 1st all cents. 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, well, i think it's great. yeah, cuz it's journeyman. we also just to decide who we want to train the who we want to work closely with it. and when we get along with no reason come with the mind clock, holmes, 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 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 you next week. and if you can handle high, maybe a better stay on the ground until then the,
