a remote island with a testament to the waters one of the many success stories, bastion of bio diverse site on november 18th ah ah, ah, what happens when people leave their home countries to go work in another? that's the big question will be addressing on this edition of mate. take germany faced with major labor shortages after world war 2. it relied on gust our bytes. i

literally guest workers to fill in the gaps. one of them was armando rodriguez de south officially proclaimed as the one millionth gast arbiter, he was gifted a moped when he arrived these days, the narrative around labor migration has shifted. and we often hear about the negative impact associated with brain drain will have more on thus, in a moments of the coming up. hi women are sidelines in product line. has been land is becoming a leader in nickel extraction on the race to find an alternative. timothy and batteries i'm sorry, just welcome to meet. you often hear people lament the fox, the poorer nations are losing their best and brightest to migration. but what if the so called a brain drain weren't actually such a bad thing? reports upon the jim bay low chaise,

a story that turns traditional perception on their head. brain brain drain. let me try it again. grange rain. i don't like the term, but what is it exactly? it's supposed to refer to the loss of skilled labor. people moving from poor countries to rich ones, but people leaving a country for a chance to realize their full potential is just part of life. i was born in the u . s. i grew up in zambia and now i live and work in germany. so why is there such a fuss when people leave a poor country for a rich one? this worry about brain drain is really a as almost that has like a neo colonial flavor to it. i think i want to keep people trapped in the places where they are, whether or not they want to leave. i think that goes against the grid, the grain of many people's values and convictions. i went to the same schools in

zambia of dorothy. she studied in russia, south africa and canada, and then she worked for some years at sam give only cancer treatment center. and then last year, she left for work in new zealand and the research. and i was to be able to research and nonrestrictive environment and environment, that's the, this so you know, if i'm not doing that, then i'm literally not utilizing my skill and i needed to be way that could be well utilized. so in a way, yes, you know, i'm contributing, but i wasn't really very utilized when i was already me. those who leave but only get to use their skills and talents. they also improve them. but this isn't just about their life. they send money to support their families back whole global remittances,

where at $719000000000.00 in 2020 remittances account for around 3 percent of indian g. d, p. for mexico. it was 4 percent of g d. p. last year. for many countries, remittances are higher than foreign direct investment, or even aid, so called brain drain, also forces governments to act, to fill the skills gap, for instance, by investing more in education. the truth is home. countries tend to have the upper hand in the global competition for talent. for me, leaving home was a difficult decision. like it is for many others. i miss them. i miss my women. i miss my women cervical cancer, particularly i think it is a very bad thing because it's a preventable disease. and

a lot of all women suffer socially. they get the voice, you know, it just socially isolating. dorothy says she will go back to them, be a one day to start her own treatment center there. the term brain drain only implies the negative. but there are many positive effects when people leave their countries. and we need to keep that in mind. moving to a new place isn't that it's challenges in our next report will meet minute new head who left her life in cairo behind to start afresh in berlin. having overcome the many bureaucratic hardballs that moving and tails, she's no thriving in a new role as a technical recruiter. here's how she did it. me, my name is mon them will have 27 years old and i'm from cairo, egypt. i studied business information system and then i completed my master's instruct punishment. i chose to charlotte to germany because it's quite

international, especially berlin. i think that it's one of the top country when it comes to the knowledge is and the moist specialize in the technical part. so for me that was a great opportunity. i'm working as a back mechanical. that's me, and i'm responsible for hiring the engineers to other companies as an expertly we, we are a consultant company so, so i'm trying to know what are the requirements of our clients and then i'm, i start to do the head hunting and for thing for all the engineers that fits with this requirement through a fast growing intro, take company from berlin, and we are hiring, tell him from all over the world. ah, the more thing that i like in the way that they see that we hope everyone is

respecting everyone and that we don't care, but from where you are and your background isn't will. but we do with fact, you mindset and that's very, very nice to find a job abroad while i'm still in europe or outside the p. and it was an easy but it's not impossible. so it just need a lot of time, a lot of effort and like i was like, almost working to find another work after my work in the mail. the challenge is finding an appointment with the government. you're in germany because it takes a lot of time. but once i have the appointment, everything went very far back and it just, i had to like, prepare a lot of documents, but my company supported me. so just give me a list of what should i prepare?

what i like them. awesome berlin, it's very international. i think like we can meet a lot of people from different nationalities in just one place and you can smell the fresh air anywhere and everywhere. mm mm. i traveled years totally along. so at the beginning i was like, okay, i need to do all my stuff by my own, and that's a huge responsibility because our culture is quite different. i used to live with my family, like this is how it is usually met. if to stay with your family until you get my i was even, don't know how to cook. honestly, i just to start to do that here in germany. ah, i really love what i do. a lot of the stuff that i was not able to even imagine that i can do it. i was thinking like all,

i can all wavelengths where not that tone, but then when it starts doing that, i was like, okay, i could do it. you can really be both so i can like wait left thing and gymnastics, and also be like a lady in my place though it doesn't have any conflicts. use the advice that i wouldn't give to any young people to travel abroad is that's actually take the step, the not think a lot of all the talented because it's really what we will all feel like it's my conference soon. i don't want to go always and we cared the from the new society. but when we do with we really explore, i was, so is an opportunity. if you feel a free in the bottom, you just have to do with me

changing traffic. now have you ever thought about how the product you use every day we're designed, whether it's the car you're driving or the piano you're playing, chances are its features were designed with a man and not a woman in mind. the implications of that bias can be dramatic men of the norm. so what about women? for the greek philosopher aristotle man was the measure of all things. women were simply the deviation from the norm. that's largely still true. today. our world is made by men for men. women often justify note. piano keyboards are designed for men's hands, and their average hand span is larger than women. one study showed that female concept pianists are more likely to suffer hand injuries as a result. smartphones aren't designed with women in mind,

but so that the average man can use them one hand it syria and alexa typically use female voice is better, better at recognizing male ones. no wonder since the algorithms were trained on men and office temperatures a standardized to suit a man who's 40 and weighs 70 kilos. 5 degrees celsius, too cold for young women. public restrooms are the same size for men and women. but men also have your, i knows, no wonder the lines are often so long for women. in medicine, the gender gap can even be deadly. heart attacks and strokes and recognize less often. and women who often have what are viewed as a typical symptoms. instead of chest an arm pain, women often have stomach pain and nausea and shortness of breath,

making it 50 percent more likely they'll be misdiagnosed. we're still waiting for female and pregnant crash test dummies. in the e u, the standard is still a man. 1.77 meters tool, weighing 76 kilos. seat belts, air bags, and seats in cars don't protect women as well. in an accident, women have a 47 percent higher risk of injury and a 17 percent higher risk of death. some female crash test dummies have finally been built. but real world performance data and testing are still needed. when it comes to men and women, the gender data gaps still needs to be closed. so that men a no longer the measure of all things. ah, the switch to renewable energy means we'll all be seeing a whole lot more electric vehicles on the roads in the coming years. according to

a recent study globe demand for lithium ion batteries is expected to rise from the current figure of around 230 gigawatt hours per year to well over $3000.00 in the year 2030 electric car. batteries are expected to account for about 2 thirds of the demand present carmakers here in europe still depend heavily on china for about 3 supplies. but the race to produce homegrown equivalence is on much depends on the availability of raw materials. in our next report will take you to a nickel mine in finland, which could help me demand lou, the land of hunger, that's good, local people used to call this area in the middle of the finish wilderness. but then geologist discovered large quantities of nickel and cobalt in the ground. all these critical, raw materials are urgently needed for the production of

e car batteries. the market is big. the company operating here sells its raw materials worldwide. and the managing director, yoni lucas, growing and can hardly keep up with the orders. his firm delivers mostly to asia, especially china. but he wants to change that. my person always is that the that the they're, they're all mother i offer here money factor law, buttery optic aysa will remain for them all thought in a german made cause. all friends, may i? dorothy, it is made cause our products on a sufficient for 1000000 l. ethical vehicle separate. that's more or less delafield bag of rocks and of the whole europe. to day telephone runs one of the largest nickel mines in europe. there are thought to be huge deposits throughout scandinavia. when europe soon switches to exclusively producing e cars,

huge amounts of nickel booking needed for the batteries. so far, china has dominated the world market in raw materials for e car batteries. 100 percent of graphite refining occurs in china as this nearly all manganese processing and the majority of cobalt nickel and lithium refining the mine side extends over 60 square kilometers the mind mineral, or is stored and irrigated in these stock piles. ready why they're human to warm and steaming. this is because bacteria help to release the critical raw materials from the rock. biological leaching or bio leaching is what the experts call it. the entire process takes 4 years and replaces the energy intensive conventional smelting process. oh,

off a seal to a footprint is then extremely important. our seal to footprint is on the other. it's 60 percent lower than i am in the us. yeah. but it's, ah, that is very important for of all of our customers in conventional production, we're smelted at extremely high temperatures. a process with a big carbon footprint which isn't necessary in the finish mind. in sweden, the company north fault has been waiting for a climate conscious raw material supplier, the company builds car batteries and wants to improve their carbon footprint. electricity for the factory already comes entirely from renewable sources. what is still missing our carbon neutral raw materials? the major component there is really energy, what type of energy debt you're feeding into your system than there are other

things always like adding recycling to your production and working and not least, which are your suppliers for components and raw materials to lower their mission. but the dominance of asian and chinese suppliers is also an important issue. as a european manufacturer of car batteries, north salt is urgently looking for more raw material suppliers with good environmental credentials. long term we want to have a more local or regional supply chain based in europe. we think that will helped also in terms of c o 2 emissions or isn't just a fractured at the cheddar farm in mine. it's also refined, for example, into nickel and cobalt basic materials for electric car batteries. that's what happens in this plant. much of it takes place inside tubes and machines are uni,

luca dornan's company is ranked the nice top mining company in the world. he says he can see that finland is experiencing a boom in the production of e car. batteries. german abbey as ha ha, going soft in a blog in audio all the fall, fall big. i'm a paradox owner. ah, you mccord which is one of the bigger producer. also we're having activities in philadelphia on have all the chances 3rd, to be a big guy mining allegation, critical raw materials for car batteries are plentiful in finland. many mines have not yet been explored. meaning the deposits throughout northern europe could even be enough to make europe's e car industry less dependent on chinese exporters. we

saw that graph earlier showing just how much demand for lithium ion battery is, is expected to rise in the coming decade. but what if there were an alternative cleaner way of storing renewable energy, but porter bina to presents from promising ideas. we all know that the future of energy is in renewables. they were the world's cheapest source of power in 2020. this is good news, but we've got a small problem. how do we store all of it? it's not sunny all the time, nor is it windy, 247. so we need a way to keep reserves. the dominant battery solution for renewables has been lithium ion, but mining pollutes exploit people and the batteries have a habit of blowing up. they don't last long enough and we're going to need a lot more capacity. enter salt water gravity, really hot air, really cold air and enormous piles of sand. could these things actually solve our

energy storage problem? so lithium ion batteries can't be the only solution to store energy, especially on a grid scale. the i. e. a says we're going to need 10000 gigawatt hours of energy storage world. why? by 2040 to me climate goals. that's 50 times the size of the current market. today it's actually pumped hydro storage that comprises a whopping 96 percent of global power storage capacity. and it basically relies on pretty simple gravitational principles. this is rami, a swami, nathan. she's the head of a thermal storage company. you've got to run worse for lakes one high and one low. and when you have a lot of excess power, you use that excess power to pump the water of pills in a higher reservoir. but you want them power back. you let the water run downstream and turn turbine generator. however, those products are hartsville, these reservoirs take up massive amounts of space and you need the right geography

to lakes and a hill. a lot of them also work within conventional hydro electric dams, which require lots of up front capital and disrupt habitat. storing renewable energy is going to need more flexibility than these reservoirs. one promising alternative that's making headway comes from something you can find right on your kitchen table. so it's much more on down and it is chemically similar to a young st robbie number if they want. this is rosa palace cine. she's a battery researcher at the institute of material science in barcelona. she says it's the best alternative because it mimics lithium ion battery technology. sodium has also got one valence electron, the number of electrons in the outermost layer. but sodium is far more abundant, is 20 to 40 percent cheaper and isn't temperature sensitive? so no blowing up, but it has lower energy density, thus heavier batteries, so it hasn't been commercialized sooner for the grid. it won't matter since

everything is stationary. right now, time is of the essence. so you might use l way higher in acknowledging the next level. ah, so much closer to the commercialization and expect them to be produced at scale in the next few years. speaking of salt, what if we could store energy in the form of heat in really hot salt swami? nothing's company malta is doing that in the us. we take electrical energy or either directly from renewable generation like wender solar or just from the grid. and we convert that into the thermal energy. turns out that molten sold is a great preserver of heat. it kind of looks like water and has roughly the same viscosity. so when there's excess electricity generated, the energy is used to heat, a large insulated storage tank of molten sold at very high temperatures. a high melting point means the salt can absorb a lot of energy,

it loses little heat and can keep it for 6 plus hours. lithium batteries manage only for when the grid needs power. the plant re converts heat back into electricity through a turbine. one of these plants would provide enough for a large town for at least 10 hours. you can do something similar with the piles of sound we mentioned earlier. a couple of finished guys decided to use some local piles to solve one of finland's biggest energy issues. heating, instead of converting feedback into electricity, they just use it directly to storage capacity. miano calling from time. i'm only doing buffers. margaret e learning co founder to company that makes sand batteries, return the letters to he's probably gonna make it still cheaper. redundant with the large volumes of energy, how much sand on the tons of sun, it can store heat at around $5.00 to $600.00 degrees from months is heat than warm municipal buildings. most importantly, it could provide heat the heavy industry sector,

which is one of the biggest emitters of greenhouse gases in cold countries is pollution makes a lot of sense. the company currently has one system that is heating can, can pay a south western town with a population of 13000. the 100 tons sand battery can technically stay hot for months, but they recharged this one in 2 weeks cycles to keep it efficient. these are just a couple of solutions. there are dozens of technologies out there each vying for their place in the market flow. redox batteries, for instance, are another big contender for grid scale storage. they don't functional that differently from lithium ion batteries. in the latter electrons travel between 2 electrodes through a liquid called and electrolyte, creating a current in a flow battery. this liquid electrolyte is stored externally. the larger the tank, the more storage capacity, which means the flow battery can be scaled really easily. and what needs scale the grid. truth is, we're not going to quit the lithium ion anytime soon. the huge demand for electric

cars means that some of the technologies and efficiencies will spill over to the grid. but the fossil fuel industry is built into the economy. it's a huge challenge to adapt entire systems, including infrastructure and policy, to renewable alternatives. at the end of the day, cost is the biggest factor limiting adoption of new technology. it'll be the market that dictates how far they've come and how far they'll go. as we come to the end of today, so on labor migration and innovation, the one thing seems clear, the more diversity, the better, the chances of good ideas coming to the for. that's certainly the case here at d w, where we have people from all over the world working in more than 30 languages. the more cultural exchange, the more innovation and creativity, whether in the communal struggle to save our planet, or the day to day conversations in the newsroom. thanks so much for watching until next time. if the bye take

with ah, with

ah, who a enabled climate neutral can actually end up harming the climax. why? because the term isn't subject to any laws, the regulations the truth behind climate neutrality.
