9:30 am
of the 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 regular blankets, the surface of the moon. the lunar pro brought to p loads of it, back to earth. one day regular might be used to build and count post on the moon, the office,
9:31 am
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 holds hidden treasure for ultimate, on the moon, the gray decimal. so regular easily to get the soles of rule materials that we could exploit to be built. and that's and you couldn't and somebody, we could build the streets on the moon, on landing sites where rootkits could landon takeoff again, stop and listen inside. excuse me, we want to make use of that rule 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 written down on that and for the adams at the technical university of but then students are testing how this sons energy might be harnessed to build routes on the moon using a bit of
9:32 am
a traditional mendoza. busy and as this came up and the system has a solar sensor, which means the lens higher level to the sun set, 2 mirrors are directing the lights, the ground god often born and 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 on a rose, on building roads from which i'm not. the moon dust becomes a storage instead of whirling around and clogging up kids and all that. i'm screaming so bad in research is keen to figure out how noun dust could be used to make things like gloss and brakes. bringing payloads from the s to the moon is prohibitively expensive. this computer. i mean, there are a lot of providers who want to transport things to the move, so it, which would cost about a $1000000.00 euros. a key though, i remember you know, the substances to recreate moon dust here on this can be found the volcanoes like
9:33 am
plus salt and felt spot, which should be as dry as possible. heated in a vacuum chamber at $1400.00 degrees celsius, the material tends into a love results. resulting motion mean reckless. looks promising. because the new one's done this yet. 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 demand and look at the possibilities of n. s and moon dust is more granular. i'm not quite as smooth itched as dusty on this home. i'm and looks like we have 2 main ingredients, bustle containing material on the notes, assign what's called tonic material. they can be mixed together to create various luminous soils. moon dust contains no water, but at 1500 degrees celsius can still make breaks with the monthly lock. the oven used to main rates would have to be abroad and a copy built on the moon. but a 100 kilo oven could process and produce many times the material i concluded in
9:34 am
generating energy on the moon is also feasible. in theory, the sun shines very brightly, i never know towns. so electricity could be produced using some of the cells along with the brakes. the students in berlin, i've been able to make los, to the gloss, needs to be as light and people as possible. then it can be turned into a, some of the. so 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 chase pearl guide, so to 1000 mean gloves with more. so the gloss with the mind moulton made on the noon and then and then a micro millimeter layer of the world sky would be applied to it. a pearl street is a synthetics crystalline material that can be dissolved into a solvent. in a vacuum chamber, it can be sprayed and then even co tons of cut off. then some copper is applied at
9:35 am
a lower temperature for all sky office. many advantages over the usual silicon and back home and out of space is close, 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 the full body brought scan, it is so solemn and all the different 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, referrals sky t in the middle. now they'll see if it works in a vacuum. the soda side is placed on to an occupational some a moment later, it's generating electricity. yeah. wow. 10 percent. wow. yeah, so is leaving a soda. so then we $31.00 kilo of perl sky to, into the mean that would give us a $400.00 squared me to layer 3 volleyball quote,
9:36 am
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 to plant a flag or collect a few pieces of lubricant stink for guns, klein. i'm fine with us on a very small scale last 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 aiming even higher. they want to live on them in
9:37 am
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 to split it can take a bit of time at 1st. a 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 see germany. now. we have the assumption of thinking that germany is the birthdays because of the way that they reconstructed themselves because of the technology. because of products that they do and i can think of living and burn
9:38 am
and it's not that much a part of those. it's not that easy to find the job as you would think. it's not that clean, that's the one thing it is. now i can see the more real face, so for then 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 a sketchy place to be in berlin. 3 guys approach were asking for money. i say they had no money, but then they took legs and at that moment they gave them the money. i started running the this my dad is the german, my parents both what to me and my brother to learn some german. busy that having
9:39 am
the 3rd language would be amazing plus in our lives 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 comment of the teacher. and during germany, you're more free to do what you want to find your own bed the monday than 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
9:40 am
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, it's riding the bike. they are quite grumpy, a safe cream to me because of the writing, so slow or making it turn in the wrong 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. so it's kind of respect basically if they're really interested in knowing what i'm doing here is that the international students, they like to talk,
9:41 am
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, no covered mountains in the andes. strange glacier formations in the south. and the on to come a 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 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
9:42 am
tower, where it reaches temperatures of more than $500.00 degrees celsius. the solved stores the heat, allowing the true buttons at the towers base to generate electricity, even when the sun isn't shining. what 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. and then we'll see how 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
9:43 am
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 deadline, if he ups or not 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 principal various salts could be used for the mixture, depending on cost and local availability. all those factors play a role in optimizing the solar solved 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
9:44 am
technology in terms of the storage materials and click on the materials used for containers like as tanks on page 11, pretty homes that they all bring their own challenges in which we have to investigate it. totally, mostly things like corrosion via and help them. once you realize you don't have during the compression you and the convention process, you consume that the in the molten salt bridge, the gap at night corps on cloudy days and the sunlight in the after come, a desert is sons usually intends to take them together. settled the cook, generate round the clock emission free green electricity, and that in turn could 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 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,
9:45 am
and even shift global power relations. this unassuming container could help make chile a global leader in green energy. it might be small, but it's the world's 1st immobile green hydrogen plant. it's 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 this on square electricity that could be generated from hydrogen friction. please 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 young either consumer. today,
9:46 am
most of chiles 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 plants, the worldwide will get anything, you know, defense in the, during the conversion with mine, we'll reuse a lot of, of it meant like this control really like the turbines and the generator road, that's the big advantage of our project. in that loving dec, i might get them, 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 a very big bench, etc, etc. because that potentially every set of electric power plant can be transformed
9:47 am
into m o 's. and so the, so plants and 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 said d as a machine, a alone instead of a 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. and the way in which we mean the great, i mean, and also do talk 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 fact my role send a signal to the rest of the world. we state and she late
9:48 am
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 paradox at the waters off the coast have a huge problem with the plastic waste. a curious more it your peers up or 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 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 i'm probably not going to get the problem because all the animals eat it rather than yes, that's bad for them. and later when we the fish,
9:49 am
we also read the plastic conical through in the image is 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, 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. what is a look at these marks made by certain cases that people don't. as the shock coils
9:50 am
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 current. so 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. have i knew 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 space on me that being even more than anger and sadness,
9:51 am
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, vicky. this is really my, they thought 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. it gives me of almost all the got them 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 to that. but i'm going to enjoy like we found plastics and other marine animals to including in the
9:52 am
intestines of fish on top plastic or. but christians are a species that help keep the clips and coils clean. and even there are no eating plastic. it's an alarming development. the marine biologists are worried are 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 plastic 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 at remote rio shingles, a tributary of the amazon river study has shown that 80 percent of freshwater fish have micro plastics in their stomach. whether that's also true for the parents that
9:53 am
live in the rain forest here is on a known box. or if your to hear a s had a different question. wire paris able to talk? birdie say this, guys, this class co c include me. why compared speaking an atomic which became the answer is fairly simple. birds have a special voice box which lets them produce out. it's called the syringe and it's located deeper in the airway than the lowering susan humans sitting though 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
9:54 am
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 7. 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 flocks, the parrots can also learn how to imitate many other sounds and sequences of sounds, which is how they learn foreign languages like human speech, the
9:55 am
can you verbs. uh uh, so you can you shoot me, can you shoot me? 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. 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, we'll 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
