or like devices presented, dw used on instagram and follow up the, the final approach recorded by the onboard camera on the chinese chunk o 6 lunar pro, as it landed on the far side of the moon in early june 2024. also on board was an instrument belonging to the european space agency, a sub which for the 1st time detected the presence of negative ions on the lunar surface. that will help scientists better understand the chemical composition of moons. this task, which is also called regulus blankets, the surface of the moon. the lunar pro brought to p. most of it, back to earth. one day regular might be used to building post on the moon, the office,

and more on this edition of dw science magazine. welcome to tomorrow. today. it might be boston literally. but the moon is in vogue again. even the powdery layer of the moon dust on the surface, holes hidden treasure for ultimate on the moon, the gray decimal, the regular hazel need some difficulty can get this thoughts of rule materials that we could exploit to be built. and that's something you couldn't. and somebody, we could build the streets on the moon, on landing sites, where rockets could longdon take off again from light on stop motion inside, excuse me. we want to make use of that roll material. what's called the only one that's available to us to build infrastructure on demand streets, habitat. so all the things we wouldn't want to bring them on for the adamant at the technical university of. but then students are testing how the sons energy might be . how honest to build routes on the moon using a bit of artificial mean,

dust on sizes came up and the system has a solar sensor which moves the lens higher level to the sun, set 2 mirrors of directing the lights. the ground got out important. picked up the energy from just a few rays of sun are enough to mount the sand team. we'd like to see a system under rugs on building roads from watched on the moon. dusk becomes a start end. instead of whirling around and cutting up kids and all that, i'm screaming so bad in research is i can't figure out how named us could be used to make things like gloss and brakes. bringing payloads from the s to the moon is precipitously expensive. this computer, there are a lot of providers who want to transport things to the move to it, which would cost about a $1000000.00 euros per kilo. i remember you and all the substances to recreate moon dust here on this can be found. the volcanoes like plus salt and felt spot,

which should be as strong as possible. hatred of i came chamber at 1400 degrees celsius. the material tends into a novice thoughts, the resulting molten mean regular looks promising. like no one's done this yet. with this, you've done it in a vacuum and it's really impressive when mainly hoping to build habitats how's these like structures the solar cells on the maintenance of the possibilities of and some moon dust is more granular on not quite as smooth and just as dusty on this or the home i'm it looks like we have 2 main ingredients. facile containing materials on the notes, assign what's called tonic material. they can be mixed together to create various luna seals. moon dust contains no voltage, but at $1500.00 degrees celsius can still make for it just wasn't meant the months to lock the oven used to meet your brakes would have to be brought on a copy built on the main office, but a 100 killer oven could process and produce many ton wise,

the material i've included in generating energy on the moon is also feasible. in theory, the sun shines very brightly, i never know clouds. so electricity could be produced using solar cells. along with the brakes, the students in berlin have been able to make gloss to the gloss, needs to be as light permeable as possible. then it can be turned into a solar cell here at the university of puts them so that the class needs to be as thin and transparent as possible. we have one, we want to produce pearl guide. so to 1000 mean gloves with more, so the gloss with the mind moulton made on the noun from them, and then a micro millimeter layer of the world sky would be applied to it, a pro scan. it is a synthetic christalin material that can be dissolved into a solvent. in a vacuum chamber, it can be sprayed and then even co tons of gloss. then some color is applied at

a lower temperature for all sky office, many advantages over the use of silicon. and back home and out of space that's cause make radiation which can sometimes not can awesome. i would replace them to fix that leads to a dfcs that damages the so to sound full but bro scan it is so sullivan. hope that if an optimist as low as she could just fly back into position. so the, so the cell could remain functional for decades even you know, to space the finish. so the cell is made of 2 glass plates with a layer of perhaps guides in the middle. now they'll see if it works in a vacuum. the soda side is placed on to an altered, special and some a moment later, it's generating electricity. yeah. wow. 10 percent. wow. yeah. so is leaving a soda. so then if we throw one t low of pearl sky to into the mean, that would give us a full 100 square meter. layer 3 volleyball court was done,

which could generate $500.00 killer watts of power researches all over the world are developing new technologies for exploring space. the biggest private competitive for luna. so the sales display origin founded by jeff, but he's also the admin can shop on it. so they were able to build a silicon. so to solve it with an efficiency of 6 percent. oh, these 10 percent. so we're doing better than blue origin yet. that's, that's the reason in this race to the main, the goal isn't just applying to flag or collect a few pieces of live rock stink for guns klein. i'm fine. we'd start on a very small scale loss and then using the energy from the 1st. so the south will make the next one is my room and eventually have a small town on the moon us, which would continue to grow. somehow for century often says lunar landing. people are aiming even higher. they want to live on them in

the germany ranks among one of the top 3 most popular countries to study and in the world one and 5 students. and for many universities come from abroad. what many of them don't realize just split, it can take a bit of time at 1st to true. feel at home here i always saw germany as a paradise. but my 1st day here in berlin, i good luck. my name is leg i am from cuba. i mean, i've exchange here and burden a nice 30 architecture. i say we're starts and expectations and this is how i feed their money. now. we have the assumption of thinking that germany is the birthdays because of the way that they reconstructed themselves because of their technology because of the products that they do and i can picture living and burning. it's not

that much a part of those. it's not that easy to find the job as you would see. it's not that clean, that's the one thing it is. now i can see the more real phase of learning to play be more casual, less formal. but that's what i like actually from the city. all of those aspects you would think about germany. so my reality and some are not the 1st day that arrived here. they went to a coffee shop. i didn't know that it was a sketchy place to be in berlin. 3 guys approach were asking for money. i say they had no money, but then they took lice. and at that moment they gave them the money i spent of running the this. my dad is the german, my parents both what to me and my brother to learn some german. they thought that

having the 3rd language would be amazing plus your life the can you to let the difference is that they bullshit the study. and that's how you learn. they pushing, especially in architecture, you're under of almost the command of the teacher. and you're in germany, you're more free to do what you want to find your own pad. the monday, then i expected. i have time, but i didn't expect to have to in germany. i was expecting for something way more intensive in germany. they enjoyed the process more, they use the free time to learn by themselves. the,

there's no much competition between students being too loose. we were like trying to compete to get a better rate than the other, whatever the german people are sometimes grantees, especially in the industry writing device. they are quite drums, the safe green to me because of the writing, so slow or making it, sir, and the wrong way. so yeah, it's good coverage for the knowing german living in berlin. it's important, i think you have to learn at least the basics of the german. so it's kind of respect basically if they're really interested in knowing what i'm doing here as i think they're nursing those students. they like to talk. they like to ask questions

about where i come from the german. so i've been pretty me really well here and they're really accepting me. so yeah, i feel like, oh, the chile is especially interesting. the scientists, in part because of the extreme variation and it's landscape snow covered mountains in the andes. strange glacier formations in the south, and the to come a desert, one of the most parched regions in the world. here astronomers use high tech telescopes to observe the skies, and there's also a rather special power plant here. the set of domains that the plant is located in the after comic desert of western shit. a 10600 mirrors are directing solar radiation to the top of the tower. the mirrors here are replacing solar cells. they're concentrated light, keeps up molten salt. it's pumped to the top of the tower,

where it reaches temperatures of more than $500.00 degrees celsius. the salt stores the heat, allowing the turbines at the towers base to generate electricity, even when the sun isn't shining. what does it, unless, i mean this technology allows us to store energy over a long time, then think what the road us see the money we can count on it and 24 hours a day, 7 days a week, lou, to a contract. and then we'll see this technology will help us in our fight against fossil fuels, especially gas and polls. incredible. and one of the biggest obstacles to renewables is storage. that's where a fossil fuels have a key advantage. molten salt could be the game changer, a continuous controllable source of energy that can be stored to balance out nature's unpredictability. the mixture of salts matters to here at the university of onto full gas. the researchers are working to optimize the recipe and further

boosted storage capacity. or the these days we use a mix that's called solar salt. so it's made of sodium nitrate and potassium nitrate and need that i believe that that makes is especially well suited to storing heat into bed, which allows us to stay on line 24 hours a day. and even when there's no incoming solar energy in it, he has a lot in an insulated tank. the super heated solid can store energy over weeks and months very efficiently. the researchers believe a thermal battery could be used that we used for about 30 years. in principle, various solves, could be used for that mixture, depending on cost and local availability. all those factors play a role in optimizing the solar solved recipe. it's cost effectiveness and its properties, but there's another problem. salts are very corrosive. a more trouble, and yet they thought are you with them? so there's still plenty of room to advance this technology in terms of the storage

materials and the materials used for containers like the tanks, fun pipes, and i've been pretty homes that they all bring their own challenges in which we have to investigate. it totally must be things like corrosion via and help them wheelchair wheels. you'll have during the compression, you and expansion process, you consume that somebody in the molten salt bridges. the gap at night corps on cloudy days and the sunlight in the other comic desert is sons. usually intends to take them together several domains that could generate round the clock emission free green electricity. and that in turn couldn't make it economically viable to produce green hydrogen. and that scale which the e u was banking on. as the energy of the future. we want to import 10000000 tons of uh, renew with hydrogen, and 2030, which is a lot at the moment. this is not available at the world market. green energy could help transform regions that have little economic cloud into a kind of gold mine and even ship global power relations. this unassuming container

creat helped make chile a global leader in green energy. it might be small, but it's the world's 1st immobile green hydrogen plant beats being tested in various locations in the desert to identify the best places for green hydrogen factories about an hour job is mainly to generate a map that will allow us to identify areas meet with green hydrogen generation could be generated especially efficiently or sometimes we want to mark the zones where electricity could be generated from hydrogen efficiently. i don't like induction. electrons, splitting water into oxygen and hydrogen takes a lot of energy and to local air and water conditions make a difference. factors like the metric pressure, temperature, and climate conditions affect the efficiency of the process of young either consumer. today,

most of chiles electricity still comes from coal fired power plants. the country wants to make the shift away from coal in and got most north of until for gas. the plans are under way to convert the 1st power plant to a molten salt facility. the planning phase has already been completed, if the swimming pool, but if this is an example for coal fired power plants, the worldwide will get anything, you know, defense. and the, during the conversion with men, we'll reuse a lot of it meant, like this control really like the turbine is in the generator road. that's the big advantage of our project. in that loving dec i might get and they get the people you do in the future, these turbines will operate using liquid solved, solar energy will heat the molten salt during the day. the project manager believes that conversion could spark a global green energy revolution. a base work site has it there a fee been shut field center because that potentially ever a set of electric power plant can be transformed into

a molds. and so it's planted molten salt energy storage solutions could also be useful in europe. for example, to smooth down fluctuations in the availability of wind and solar energy. the 1st projects are in the works, but one challenge remains. the power grid will 1st have to be adapted to renewable energy. we the d as in tina, a alone instead of a 10 to 20 percent of renewable energy is lost, as he said, we had to throttle the energy input. uh, that's due to lack of capacity in the transmission grid and the way in which we mean the grid on me and also do tucked under an investment incidence to me soon. conditions in july aren't entirely applicable to the rest of the world. but the rethink that's happening here can help spark new scientific insights, technical solutions and investment opportunities. and that mike will send a signal to the rest of the world. we state and she lane

and easter island also called robin noise, which lies 3500 kilometers from the mainland. the island is famous for its giant, ancient human figures, carved into stone at 1st glance. revenue, it is a paradise. but the waters off the coast have a huge problem with plastic waste. a curious more it your peers up to with the camera. its vision is poor, otherwise it would have been able to see what's headed its way. even 20 meters down the waters near at easter island or caused by the we as the islanders call. it are beautifully clear at 1st glance because they're actually full of micro plastics. marine biologist come up here and we'll go pick them. you are studying the impact of plastic waste on marine ecosystems as an implant of what gets a problem because all the animals eat it rather than you know, that's bad for them. and later when we the fish,

we also have the plastic holes in the plastic while i didn't know what i mean. they're focusing on a specific seat or space these. this population has been declining dramatically. the reasons are still unclear, but what is apparent is that more and more micro plastics are accumulating and then we found that christian, it was higher and there aren't that many anymore. we'll take it to the lab to study it at the beach, in the shadows of the famous wise catches due to burns and a team of volunteers are getting to work in a spot where towards strongly bask in the sun. there marking out an area with a clear the plastic that washes on shore here every day. there's huge amounts of it, and it's a problem all the way up and down the food chain. some pieces have visible bite marks on them. what is a look at these marks made by certain cases that people don't. as the shock coils

colonize the plastics in the ocean and that attracts the 1st fish. you just click on the sun as soon as small fish are on the plastic to big fish like sharks come to eat them and they end up eating the plastic to cool. man. bless the micro plastics or plastic particles with a diameter of less than 5 millimeters. and up everywhere they float to the top of the bucket where they're fished out. and just over half an hour, they've collected 8 kilos. the plastic arrives here from all over the world carried by ocean currents and gathers into 5 enormous board texas, a plastic called gyre. one shy or is in the south pacific and easter island has the misfortune of being situated near the edge of it. have i knew weeds recycling center can't handle all the plastic waste manager alexander to key shows us an area outside, piled high with trash, fish from the ocean. you might get a lot of the space on me that being even more than anger and sadness,

i almost said, i feel pretty simon, that we mortal beings on this planet, aren't able to come together and recognize what a problem. this is the case, this employee, lima, they throw those industrial nations especially need to clean up their act. the mayor of copeland, we tells us being focused on what's wrong to call a country develop. if it produces garbage, they use a country is only really developed when it thinks about what it's leaving behind for its children. it gives me of almost all the items on what sort of equals the c arch and fished out of the ocean is now in the laboratory. it's contaminated to what do you see at black plastic? the plastic fibers don't break down. instead they accumulate inside fish and other sea creatures affecting the entire marine food chain are going to enjoy, like we found plastics and other marine animals to including in the intestines of

fish on top less equal. but c, urchins are a species that help keep the clips and coils clean the even. there are no eating plastic. it's an alarming development. the marine biologists are worried the most likely that we have to change our consumption habit, recycle and dispose of plastics properly and keep it out of the ocean. i see gloves cannot, the earth is weeping. we have to stop put on the brakes that can't go on like this, and that is the plastic the so you to see the marine biologist on easter island. want to raise awareness around the world. the plastics washing shore. here on the hop on, we are everyone's problem. there's hardly anywhere in the world that's free of plastic nowadays. even at remote real shingles, a tributary of the amazon river study has shown that 80 percent of fresh water fish have micro plastics in their stomach. whether that's also true for the parents that

live in the rain forest here is on a known box, or if you're to hear us had a different question. wire parents able to talk. rudy save this guy. this guy cho include me. why compared speaking an atomic me speaking the answer is fairly simple. birds have a special voice box which lets them produce sound. it's called the syringe and it's located deeper in the airway. then the lowering says in humans sitting though in the airway, with a tricky a branch towards the lungs. the ceilings is lined with a last stick membranes whose tension and position can be controlled super new sound . the

parents which have unusually large and muscular tongues, can modulator vocalizations to create an enormous range of sounds. anatomy is one aspect, but parents are also covered there among the most intelligent animal species i can put on quite a show. and parents can also learn to imitate voices and sounds. in the wild pirates often live in large groups, having a characteristic vocalization makes it easier to locate their off spring or make power. it's also imitate a variety of sounds and the pitch of their mates and birds. and their flock, the parents can also learn how to imitate many other sounds and sequences of sounds, which is how they learn foreign languages like human speech, the

can you verbs so you can you shoot me, can you shoot, but can you call the parents can their new words throughout their life, but that doesn't mean the oldest parents have the largest repertoire. african grey parents are the most talkative of all, which is part of what makes them so popular. very good. let us read, why do you have a science question then send it to us as a video, text or voice message. if we answer it on the show will send you a little surprises to thank you. so come on, just ask that wraps it up this time on dw science show. thanks for joining us and hope to see you again
