12:30 pm
nice the nice get their home phone there in baby's shuttle stops august 3rd on d. w. 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 moon does this dust which is also called regular blankets the surface of the moon. the lunar pro brought to kilos of it back to earth. one day, franklin might be used to build in town post on the moon, the office,
12:31 pm
and more on this edition of dw science magazine. welcome to tomorrow today. or it might be boston, lovely, 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 gets a soul. several materials that we could exploit to deal with 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 the main 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 this sons energy might be harnessed to build roads on the
12:32 pm
name using a bit of a traditional main dest ones. as this 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 god often for them 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 rugs on building roads from watched on the moon just becomes a starting instead of whirling around and talking up kids and all that. i'm screaming so bad in research is keen to 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, i mean there are a lot of providers who want to transport things to the move, which would cost about a $1000000.00 euros per kilo. i remember, you know, the substances to recreate moon dust here on this can be found the volcanoes like
12:33 pm
plus 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 like to say no one's done this yet. it isn't 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 maintenance of the possibilities of and some moon dust is more granular. i'm not quite as smooth interest as dusty on this home. i'm on. 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 luna soils. moon dust contains no voltage, but at 1500 degrees celsius can still make breaks was the monthly lock. the oven used to main rates would have to be brought from a copy built on the main office, but a 100 killer oven could process and produce many ton life. the material i've included
12:34 pm
in generating energy on the moon is also feasible. in theory, the sun shines very brightly and never know towns. so electricity could be produced using solar cells. along with the brakes, the students in berlin has been able to make los to the gloss, needs to be as light permeable 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 one ship which is pearl skype. so to styles on main gloss, with more so the gloss with the mind moulton made on the noon and then a micro millimeter layer, referrals guides will be applied to it. a pearl street is a synthetic crystalline material that can be dissolved into a solvent. in a vacuum chain or it can be sprayed and then even co tons of cut off. then some
12:35 pm
copper is applied at a lower temperature for all sky office. many advantages over the usual silicon and back home. and out of space that's 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 sky, did so solve it all the different optimist. as long as 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 altered visual and 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 into the me, and that would give us a full 100 squared me to layer 3 volleyball quote,
12:36 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 display 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 here. that, that region in this race to the main the goal isn't just applying to flag or collect a few pieces of living. rock, stinking guns, klein, i'm fine. we'd stuff on a very small scale last then using the energy from the 1st so the south will make the next one is my mom 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 demand.
12:37 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 at home here i always saw germany as a paradise. but my 1st day here in berlin, i good luck. my name is mag. i am from cuba. i mean, i've exchange here and burden a nice are young to victor. i say we're 3rd going to click the issue. 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 the technology because of products that they do and i can things are living and burned
12:38 pm
. and it's not that much of 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 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. i forget you place to be in berlin. 3 guys approach me asking for money. i said i 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 what me and my brother to learn some german. they thought that
12:39 pm
having the 3rd language would be amazing. plus your life the can to let the difference is that they push it to 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 that i didn't expect to have here 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,
12:40 pm
there's no much competition between students being too loose. we were like trying to compete to get the better rate than the other, whatever the german people are sometimes grantees, especially in the industry. it's 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. so it's kind of respect basically 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 to ask questions about where i come from,
12:41 pm
the germans. i've been pretty mean really well here. and they're 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 snow 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 have service guns. and there's also a rather special power plant here. the settle told me 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 are concentrated, light keeps up molten salt. it's pumped to the top of the tower,
12:42 pm
where it reaches 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 isn't shining. 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 care on it and 24 hours a day. 7 days a week, lou to is going to that then that will see this technology will help us in our fight against fossil fuels, especially gas and holes. 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 gas. the researchers are working to optimize the recipe and further
12:43 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 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 solve recipe, its cost effectiveness and its properties. but there's another problem. salts are very corrosive. whichever thing at the federal youth. and
12:44 pm
so there's still plenty of room to advance as technology in terms of the storage materials and click on the materials used for containers like the tanks on page 11, pretty homes that they all bring their own challenges in which we have to investigate. you told me i see things like corrosion view and help them once you realize you don't have during the compression you and expansion process, you consume that the in the molten salt bridge, the gap at night or on cloudy days and the sunlight and the out to come a desert is sons usually intends to take them together, settled only now 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 is banking on. as the energy of the future, we want to imports 10000000 tons of uh, renewed 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
12:45 pm
a kind of gold mine 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. 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 to fish in place. i don't like industrial and collect splitting water into oxygen, and hydrogen takes a lot of energy and to local air and water conditions make a difference. the factors like the metric pressure, temperature, and climate conditions affect the efficiency of the process of you, either consumer. today,
12:46 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 gone most north of until for gas though. plans are under way to convert the 1st power plant to a molten salt facility. the planning phase has already been completed, if the sewing machine flow, but this is an example for coal fired power plants, the world wide book is 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 that loving dec, i might get them, they get the people get to in the future. these turbines will operate using liquid solved, solar energy will heat the molten salts during the day. the project manager believes the conversion could spark a global green energy revolution. a base work site has that there are a big bench, etc, etc. because that potentially every set of electric power plant can be transformed
12:47 pm
to m o 's. and so it's planted molten salt energy storage solutions could also be useful in europe. for example, to slow 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, the d as in chile alone instead of 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. great, uh, 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's my role send a signal to the rest of the world. we stay in sheila
12:48 pm
and easter island also called robin noise, which lies 3500 kilometers from the mainland. the island is famous for its jillian ancient human figures carved into stone. at 1st glance revenue, it is a paradox, but the waters off the coast have a huge problem with plastic waste. a curious more of 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 husband 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 one problem of what gets a problem because all the animals eat it rather than yep,
12:49 pm
that's bad for them. and later when we the fish, we also have the plastic conical to be in the plastic is what i mean. they're focusing on a specific seat or species whose population has been declining dramatically. the reasons i still unclear but what is apparent is that more and more micro plastics are accumulating and then we found a c arch and it was hired. 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 why statues, 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 certainty so that people
12:50 pm
don't or the shock coils colonize the plastics in the ocean, and that attracts the 1st fish. you just click on this them as soon as small fish are on the plastic or 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 flow 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 gyre. one tire is in the south pacific and easter island has the misfortune of being situated near the edge of it. have a new ways 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, you know, based on me that being even more than anger and sadness,
12:51 pm
i almost see it. i feel pretty side man that we mortal beings on this planet aren't able to come together and recognize what a problem this is. vicky is this employee my the, those industrial nations especially need to clean up their act the mayor of got when we tell 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 unless it will be close to see arch and fished out of the ocean is now in the laboratory. it's contaminated to what do you see at the black plastic the plastic fibers don't break down. instead they accumulate inside fish and other sea creatures affecting the entire marine food chain. is that what i'm going to enjoy? like we found plastics and other marine animals to including in the intestines of
12:52 pm
fish on top left the cool. but c, urchins are a species that help keep the clips and quarrels 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 glasgow. nothing mean 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 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 and their stomach. whether that's also true for the parents
12:53 pm
that live in the rain forest here is on a known box, or if you're to hear us had a different question, why are parents able to talk birdie say this guy, this guy? tell me why compared speaking an atomic which became the answer is fairly simple. birds have a special voice box which lets them produce, 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 elastic membranes, whose tension and position can be controlled to produce sound. the
12:54 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. 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 accounts to restrict vocalization makes it easier to locate their off spring or make power. it's also imitate a variety of sounds and the picture 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
12:55 pm
can you verbs a so you can, you shoot me, can you shoot, can you call 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, 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
12:56 pm
soon on tomorrow today. good bye. and show the
