11:30 pm
as we say, there is never giving up every weekend on d. w the the final approach recorded by be 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 to better understand the chemical composition of moons. discussed, which is also called regular blankets. the surface of the moon, the lunar pro brought to kilos of it back to earth. one day regular might be used to build and found post on the moon, the office and more. i'm this edition of dw science magazine.
11:31 pm
welcome to tomorrow. today. it might be boston lovely, but the moon, it seems like again, even the powdery layer of moon dust on the surface, holes hidden treasure for ultimate on the moon, the gray, desolate, irregular hazel need some difficulty gets a source of rule materials that we could exploit to develop looks like 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 role material was the only one that's available to us to build infrastructure on the main streets, habitat. so all the things we wouldn't want to the written down on the adamant at the technical university of but then students are testing how this sons energy might be harnessed to build roads on the moon using a bit of
11:32 pm
a traditional moon dust ones. as this came out 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. colorado important picked up. the energy from just a few rays of sun are enough to mount the sand team. we don't have seal system on the rugs on building roads from watched on the moon just becomes a solid instead of whirling around and coming up key is wonderful that i'm screaming the band in research is keen to figure out how named us could be used to make things like gloss and breaks, bringing payloads from the s to the moon is precipitously expensive. this computer, i mean, there are a lot of providers who want to transport things to the move, which would cost about a 1000000 euros kilo. i remember, you know, the substances to recreate moon dust here on this can be found the volcanoes like
11:33 pm
by salt and felt spot, which should be as strong as possible. heated in a vacuum chamber at 1400 degrees celsius. the material tends in to allow her to thoughts resulting motion mean reckless. looks promising because one of the new ones done this. yeah, it does. and with this you've done it in a vacuum and it's really impressive when mainly hoping to build competence houses like structures, the soda cells on the name and the possibilities of and some moon dust is more granular. i'm not quite as smooth. and just as dusty on this home i'm on, so it's like we have 2 main ingredients, bustle containing material on the notes, assign the whole conic material. they can be mixed together to create various luminous cycles. moon dust contains no voltage, but at 1500 degrees celsius can still make breaks with the monthly lock, the oven used to main, right, and so would have to be brought from a copy built on the main office, but a 100 kilo oven could process and produce many times the material i've included in
11:34 pm
generating energy on the moon is also feasible. in theory, the sunshine's very bright me, i never know towns. 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 people as possible, then it can be turned into a soda. so here at the university of puts them so that the class needs to be as thin and transparent as possible. by the come on, 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 noon from them and then a micro millimeter layer of the world sky would be applied to it. a pro site is a synthetic christa being 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 copper is applied at
11:35 pm
a lower temperature for all sky office, many advantages over the usual silicon and back home. and out of space is causing the radiation, which can sometimes not can awesome out of place. and the fact that leads to a dfcs that damages the so to sound the supervisor brought scanning did. so solve that. if an optimist is slow, she could just slide 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, referrals sky t in the middle. now they'll see if it works in a vacuum. the soda side is placed on to an artificial in some a moment later. it's generating electricity. yeah. wow. 10 percent. wow. yes, i was leaving a soda. so then, if we throw one kilo of pearl sky to onto the me, and that would give us a full 100 square meter layer 3 volleyball court,
11:36 pm
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 is blue origin founded by jeff, but he's also having to shop on it so they were able to build a silicon. so the cell with an efficiency of 6 percent. oh is, is 10 percent, so we're doing better than blue origin hits that, that blue origin in this race to the main. the goal isn't just a pond to flag or collect a few pieces of lou wrong. stinking 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 cell 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 raining even higher. they want to live on the main.
11:37 pm
the germany ranks among one of the top 3 most popular countries to study and in the world. one and 5 students at 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 it 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 and i started going to victor. i say we're searching expectations. and if it's how it feeds everybody know, we have the assumption of thinking that germany's the birthdays because of the way that they reconstructed themselves because of the technology. because of products that they do and i can things are living and burned and it's not that much of part
11:38 pm
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 clearly maybe more cash or 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 i arrived here, they went to a coffee shop. i didn't know that it was their skin. she place to be in berlin. 3 guys approach me asking for money. i say they had no money, but then they took legs and at that moment they gave them the money i spent of running the this. my dad is the german, my parents both worked at me and my brother to learn some german. they thought that
11:39 pm
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 pushed, especially in architecture, you're under of almost the comment of the teacher. and during germany, you're more free to do what you want to find your own bed. the monday then i expected. i have time that i didn't expect to have to in germany . i was expecting for something way more intensive to in germany. they enjoyed the process more, they use the free time to learn by themselves. the,
11:40 pm
there's no much competition between students. in to least we were like trying to compete to get a better rate than the other or whatever the german people are. sometimes grantees, especially in the industry writing the bike, they are quite drummed the safe green to me because of the writing, so slow or making it, sir, and they're all way. so yeah, it's good coverage for the knowing german living in berlin is important. i think you have to learn at least the basics of the german fund of respect. basically they're really interested in knowing what i'm doing here. i was, i think they're national students. they like to talk. they like to ask questions
11:41 pm
about where i come from the germans. so i have been pretty me really well here. and there really accepting me. so yeah, i feel like, oh the sheila is especially interesting to scientists in part because of the extreme variation and it's landscape. no covered mountains in the andes. strange glacier formations in the south, and the common desert, one of the most parched regions in the world. here astronomers use high tech telescopes to a service kind and there's also a rather special power plant here. the set of told me that the plant is located in the outer comic desert of western chit, a. $10600.00 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
11:42 pm
temperatures of more than $500.00 degrees celsius. the salt stores the heat, allowing the true buttons at the towers base to generate electricity, even when the sun is in china. what does is it i must, 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 in the 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 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 guardstock. researchers are working to optimize the recipe and further
11:43 pm
boosted storage capacity. or the these days we use a mix that's called solar salt because 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 online 24 hours a day and even when there's no incoming solar energy to line, it keeps 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 salts could be used for the mixture, depending on cost and local availability. all those factors play a role in optimizing the solar solve recipe, its cost effectiveness and its properties. but there's another problem. salts are very corrosive. whichever thing at the federal youth. and so there's still plenty of room to advance this technology in terms of the storage
11:44 pm
materials and click on the materials used for containers like as tanks fine 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 and help them. we're not here. we also don't have during the compression you and expansion process, you consume that the mother in the molten salt bridge, the gap at night or on cloudy days. and the sunlight in the after comma desert is sons usually intends to take them together. settled only that though it could generate round the clock emission free green electricity, and that in turn could make it economically viable to produce green hydrogen at scale, which the e. u was banking on. as the energy of the future, we want to import 10000000 tons of a renew with hydrogen in 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
11:45 pm
could help make chile a global leader in green energy. it might be small, but it's the world's 1st mobo green hydrogen plant. it's being tested in various locations in the desert to identify the best places for green hydrogen factories. to see 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. don't like industrial, electric, splitting water into oxygen and hydrogen takes a lot of energy and of local air and water conditions make a difference. the factors like our metric pressure, temperature, and climate conditions affect the efficiency of the process of you, either consumer. today,
11:46 pm
most of chillies electricity still comes from coal fired power plants. the country wants to make the shift away from coal. in i'm 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 plant and worldwide look at anything . you know, defense in the, during the conversion with men will reuse a lot of what meant like this control really like the turbine. it's in the generator road. that's the big advantage of our project in the loving decker market . 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 works a has a 3 big bench, etc, etc because that and potentially every set of electric power plant can be transformed
11:47 pm
to m o 's. and so the plan to 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 vs instead of a d. as in tina, a alone and scale to 10 to 20 percent of renewable energy is lost, as he said, we had to throttle the energy input. that's due to lack of the capacity in the transmission grid. uh and the way in which we mean the great and also do tucked under an investment instead of somebody soon. conditions in july aren't entirely applicable to the rest of the world. but the re think that's happening here can help spark new scientific insights, technical solutions and investment opportunities. and that's my gross and a signal to the rest of the world. we state and she lane
11:48 pm
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 at the waters off the coast have a huge problem with plastic waste. a curious more it your peers up or the camera. it's vision is poor, otherwise it would have been able to see what's headed its way. even 20 meters down . the waters near 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 yep, that's bad for them. and later when we the fish,
11:49 pm
we also have the plastic so close to the plastic while i didn't know what i mean. they're focusing on a specific seat or can space the 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 hired. there aren't that many anymore will take it to the lab to study it at the beach, in the shadows, at the same is why statute 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. when they say, look at these marks made by scientists say that people don't or the shock coils
11:50 pm
colonize the plastics in the ocean, and that attracts the 1st fish you this with 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 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 shire. one tire is in the south pacific and easter island has the misfortune of being situated near the edge of it. hop on new waves 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 open space on me that being even more than anger and sadness,
11:51 pm
i almost see it. i feel pretty fine man, that we mortal beings on this planet aren't able to come together and recognize what a problem this is. vicky this is really my, they, those industrial nations especially need to clean up their act, the mayor of god. when we tells us being so he's done 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. we give you buy most of the got them on most of those because the c arch and fished out of the ocean is now in the laboratory. it's contaminated to what do you see? black plastic. the plastic fibers don't break down. instead they accumulate inside fish and other sea creatures affecting the entire marine food chain to that . but i'm going to enjoy like we sent plastics and other marine animals to including in the intestines of fish on top plastic cool. but c, urchins are
11:52 pm
a species that help keep the clips and coils clean the fine even. there are no eating plastic. it's an alarming development. the marine biologists are worried of the get. the most likely that we have to change our consumption habit, recycle and dispose of plastics properly and keep it out of the ocean sea glass and not the earth is weeping. we have to stop put on the brakes that can't go on like this, and that is the political, the. so you'd see the marine biologist on easter island. want to raise awareness around the world. the plastics washing shore here on the pipeline. we are everyone's problem. there's hardly anywhere in the world that's free of plastic nowadays. even that remote rio shingles, a tributary of the amazon river study, has shown that 80 percent of freshwater fish have micro plastics in their stomach.
11:53 pm
whether that's also true for the parents that live in the rain forest here is on a known box, or if your to hear us had a different question, why are parents able to talk birdie say this, guys, this class tow? see a good why compared speaking an atomic mitch speaking? the answer is fairly simple. birds have a special voice box which lets them producer, found it's called the syringe and it's located deeper in the airway than the lowering susan humans sitting low in the airway with a tricky a branch towards the lungs. the ceilings is lined with a lastic membrane whose tension and position can be controlled super new sound. the
11:54 pm
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. are 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
11:55 pm
can you verbs or uh, so you can, you shoot me. can you shoot me, can you call us to 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. the 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 the 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 soon on tomorrow today. goodbye and show
