the don't take money. they said to my son, your mom is not coming back. over february 2020 russian troops invaded the ukrainian city of the computer. it was recaptured. 6 months later. the occupation was hard. how can life go on after all the terror? not everyone can do with the fear we felt every day when russia comes starts august 25th on dw, the cooling bass, flickering lights, and then the electric moods clubs are a place of co star. so it's for many people looking to burn some energy,

but they also cost a lot of energy in a club uses as much power and $1.00 weekend as a one person household does in a year. but that's meant to change with the power of dance. how can we produce renewable energy with our own movement? that's one of the topics on this week's edition of made data of use business magazine. i'm of the that welcome to the show and also coming up micro plastics. a simple solution for a big problem. mega greenhouse kind of be sustainable and massive demand. how a business of attracting trainees. just one step can take us in the right direction. that's the idea behind energy harvesting. no matter whether it's on the dance floor or on the way to the office. we produce energy everywhere, we go seizing that energy means being one step closer to the future. the sun wind. 3 and water are considered the most important sources of

renewable energy. and what does dancing have to do with it? most link 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 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 of important to us, you know,

kind of what 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 of this of to 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, or coupled with the turbine. moving the turn, charles 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 or all tech systems or movements you move much, all the other sort of 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 functioned as roof tiles. entire roofs could be covered with them in the future. the 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 so if i didn't drop a little thing solution at the moment to be on yours 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. straightforward answers with should results. that's what's needed to protect our planet. it's the same when it comes to finding micro plastics. the tiny particles often result from the breakdown of larger plastic items like bags and bottles. micro plastics are infiltrating our legs, rivers and oceans. a problem with huge environmental repercussions. one business wants to solve it with a simple solution. in 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 bubbles 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, an entrepreneur, and a successful visionary. perhaps maybe people blossom oppressors leaning wastewater with micro bubbles as a new ones learned at an electron 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 it's have fun javascript years 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 saw out of a way to crate and adherence technology for the water with a ton of must be flowed freely in the water, well, cleaning it by salt alone. small beginnings and the labs. the challenge was to create bubbles sooner than a hair. so that as many plastic particles as possible, what it here to them the then the project group,

the 1st prototype was called dumped one, which works on a pond. it was the 1st $0.06 for the dump 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 adhered to the bubbles. ready they literally stick to them, and that's migrate to the surface. the a lot of different kinds of i'll here to here and check now just can be used wherever mike or plastic hotspots arise or are found it 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 console. and we did it without chemicals. just with pure

micro level technology. 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 in heavily polluted rivers such as in asia, before the plastic reaches the oceans and spreads from there. we have a lot of guns and we still have plenty of challenges ahead of us. yes. 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 gone, but we still have to find all of the haystacks in almost a mile from and some of them see 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 for those of us with a green thumb spring and summer mean spending lots of time gardening. but where does the plans that adorn our balconies in front yards come from in europe? a lot of them were grown in the continents biggest green house in northern germany . it's spans more than 80 football fields. and it's owners don't just have a green sun. they have their hands completely full. that's because they want their business to flourish sustainably. of the manual work in automation and technology combines here $300000000.00 balcony in garden plants, plus vegetables for all of europe are produced. this is emma seller and the company has the largest greenhouse in europe, which is larger than 80 football fields. 5 factors that did the company's success.

the 1st reason, ecology see equipment is our to our guide biking around the 1.4 kilometer long greenhouse is the healthiest and most practical way for most of the companies. 400 employees to get around this week that harvesting 120 tons of tomatoes, the new blossoms need to be pulled and needed. some more tomatoes will grow. insects do some of the most vital work that since we have, we have several 100000 bumblebees here. they're very important and blowing info. some told the lady bucks help to buy eating harmful agents. other beneficial insights such as lay swing larvae,

also inaction together. they reduce the need for chemical insecticides. reason number 2, automation robots like this complaint $15000.00 cuttings per hour. it's the only way to replant entire halls with asters. one invention that was used to you for the 1st time is trays like these. these 6 packs of lavendar will be delivered to this account, supermarket, automated vehicles, pick up the merchandise. the reason number 3 locations. the green houses are located in the middle of europe, in germany, close to the doctor border. company bus tom, sleepers has built new green houses all around the company headquarters. and for him, it was the right decision between fedex and the only located next to the highway

and have great north south and east west connections. and we can reach anywhere in europe quickly. that's a huge advantage for us of use and full sized feelings. the ceilings were delivered from the company's branch. indeed, the obeah, you have the capital that is of a slower greenhouse. there employed some 600 d. b open workers to cultivate young plants. the reason number for family today, the grandchildren are in charge. the company was founded in 1954, but young people as it was, not until the 19 ninety's that it became an industry leader. now, tom sweepers and his siblings tend to the family business. he's well versed. no. the latest. the technical innovations. let's go strongly believes in a family business model. then let's noise must be. do you want to do something new

and bring you any return for 5 or 10 years? companies listed on the stock market want to see profit so immediately time the businesses just want to see that they'll be around in 10 or 15 years on, on dicing. reason number 5, resources, water for irrigation and heat. so the plants in winter greenhouse businesses normally consume a lot of boat. but here, things are more efficient. the solar panels are mounted on the roof and the excess electricity generated is fed back into the electrical grid. and every day the, the green houses are heated with wood waste, not gas, peak, and logically, it's the better choice and much cheaper than what many other greenhouses use. the heating also supplies of wood fire color plants more than is needed for the greenhouse. so the excess is set back into the network. we've only want to eat in

a climate neutral way. we produce luxury products and you have to be able to buy them with a clear conscience. so i think we have to move away from fossil fuels for most of the evac rainwater from the roofs of the 90 hector facility is collected in basins like these and fed into an irrigation system not totally. so of course it costs something, but it's also healthier for the flowers. rainwater doesn't contain as much lime and that's the other great benefit plants know of rain water, because if i saw fertilizer is added to these base. and so each type of plan, according to the company, they are self sufficient when it comes to water. because the floors are sealed, and the water that comes from above is collected below and recycled. calling all the main reason why the company has been able to grow so dramatically is it's economical use of both money and resources

being economical with precious resources on minimizing pollution. if the mission that has to drive our economy, that's also why more and more electric cars are driving on our streets. but for many vehicles, electric engines aren't an option the heavier the vehicle. and the longer the distance that has to travel the less likely can run on a battery. that's why, tractors and trucks are still powered by traditional engines, meeting massive amounts of c o 2. now one business is banking on hydrogen. as a solution, the, 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 we see the advantages of

a hydrogen combustion engine? when it comes to heavy duty vehicles on 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. in that way, all diesel engines get refitted instead of being chunked. the pistons among 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 in the evening, come after the using this 7.8 liter diesel engine that we've said with hydrogen components. and you said,

because in hub we left everything the way it was because the engine's a good starting point. that's why we chose that just added the hydrogen component of components that on the boat, we convert basic diesel engines into hydrogen and jobs. and lots of stuff most all i gave you and also has a very low ignition temperature, which means you need very little energy to ignited. that's why we need to install an ample amount of control technology. the engine is being stress tested using a continuous load. it's scheduled to go into series production by 2024. it's are to 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 84 by 2050 by such tough hudson that to alicia.

if you want to have hydrogen on the road, then you have to fulfill certain requirements involved in the whole like building filling stations. it's often 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 were only a few hydrogen cars around 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 affinity of them from 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. in 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, vintage, and vehicles, unless you know you have a very large machine that has c, 300 horse power. and it's run with a heavy load for a long time. is when it needs a loss of power the machine no. such as with excavators, whitestone, then you need so much energy, the box or they would come to getting bigger and bigger. i missed the, the bought the year. even with an excavator, at some point that it's hard for me to build it big enough back to the think about that. even if that's something the necessary infrastructure is built, then hydrogen engines could help to create the more climate friendly future germany, the economy is experiencing a severe work or shortage. more than half a 1000000 positions are left unfilled. that's why i desperately need more people to move here at the same time. tough immigration rules have made jeremy les attractive

for foreigners who prefer to settle in more well coming, less bureaucratic countries. that's meant to change. now. how much immigration does germany need? 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 age long could not see itself as a country of immigration. but gotcha, 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 for the things hurdles and a lack of accept the canada has long shown how things can be done better. they are new citizens are invited to an efficient naturalization ceremony. but before that, the migraines have to qualify in 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, the german businesses aren't only struggling with general work or shortages. they're also missing young people. many vocational training positions remain vacant . only a couple of years ago, the script was flipped. young people had to join a long waiting list to get a training ship at a company. now it's the businesses for courting applicants. one roofing company in berlin is determined to stand out above the rest. it's reeling an applicant with a challenge. 30 meters 5 in a swinging basket. it's a test. every applicant has to pass. and it's part of the trainee challenge and

a portland roofing company. they're 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, i was just, 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 ok. now logistics, restaurant work, waiter logistics. dishwasher work in clubs, a cemetery gardener to scout not on this end please. now is he just has to go up on the crane and prove that he can work a lot of nervous putting good spirits. it's all secured because of because it's of nicholas trice who's handed welding

the business. it's not that easy as you can see here. 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 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. 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 say he's going to say, well, i think it's great. yeah, cuz the journeyman we also get to decide who we want to train the who we want to work closely with. and when we get along with reason con would be my tackling the applicants wait for the results, then the winters are announced as easy as one of them. nicholas can also start his room for apprenticeship of 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. and that's it for this episode of made. if you have an idea for new and if it's of ways to create energy, let us know we will be back next week with a new episode. good bye and take care the
