7:30 am
sized disgusting. w series about our complex relationship with animals need to be watch now on youtube. d. w documentary. 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 moon does this dust which is also called regular 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 build in town post on the moon, the office,
7:31 am
and more on this edition of dw science magazine. welcome to tomorrow. today. it might be boston literally. but the moon, it seems like again, even the powdery layer of the moon, dust on the surface holds hidden treasure. for ultimate on the moon is gray, desolate, so regular, and we'll need some definitely gets a source of rule materials that we could exploit to look something 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 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 written down for the academy at the technical university of but then students are testing how this sons energy might be harnessed
7:32 am
to build roads on the moon using a bit of o, just visual mean dust 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. colorado important picked up. the energy from just a few rays of sun are enough to mount the sand team. we don't have c o system on a rugs on building roads from watched on that the moon dust becomes astonished. instead of whirling around and cutting 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, 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
7:33 am
plus salt and felt spawn, which should be as strong as possible. can you do it in a vacuum chamber? at 1400 degrees celsius, the material turns into a love results resulting motion mean reckless, looks promising. this is one of the way to say 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 competence houses like structures, the soda cells on the name and the possibilities of and some moon dust is more granular and not quite as smooth itched as dusty on this. the home i'm and looks like we have to main ingredients, fossil containing material, on the notes assignment level conic material. they can be mixed together to create various luminous soils. moon dust contains no voltage, but at 1500 degrees celsius can still make breaks, 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 kilo oven could process and produce many times the material i've included in
7:34 am
generating energy on the moon is also feasible. in theory, the sunshine is very bright, me, i never know towns. so electricity could be produced using some of the 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 some of the. so here at the university of puts them so that the class needs to be as thin and transparent as possible. come on, we have one, we, one should, which is pearl skype. 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 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
7:35 am
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 knock an item 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 object 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 mean, that would give us a full 100 square meter layer 3 volleyball court,
7:36 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 is blue origin founded by jeff, but he's also having to shop on it so that they were able to build a silicon. so the cell with an efficiency of 6 percent of these 10 percent. so we're doing better than blue origin, yet that that blue origin in this race to the main, the goal isn't just to plant a flag or collect a few pieces of living, rock, stinking for guns, klein, i'm fine. we'd start on a very small scale lots and then using the energy from the 1st so the cell 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 after the 1st lunar landing people are raining even higher. they want to live on the main,
7:37 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 just that 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 or young to victor. i say we're starts and expectations and visits how it fits everybody know, 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 and it's not that much of our days. it's not that easy
7:38 am
to find the job as you would see. it's not that's 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 a sketch you place to be in berlin. 3 guys approach were asking for money. i say they had no money, but then they took lights. and at the moment they gave them the money i spent of running the this my dad is the german, my parents both. busy me and my brother to learn some german,
7:39 am
they thought that having the 3rd language would be amazing. plus, you know, or less the can you to let the difference is that they push it to study and that's how you learn. they pushed, especially in architecture, you're under of almost become end 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 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
7:40 am
there's no much competition between students in jewelry. so 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, 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 fund of respect. basically they're really interested in knowing what i'm doing. 0 as i think they're nursing those students. they like to talk. they like to to ask questions about where i come from
7:41 am
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 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're concentrated light keeps up molten salt, its pumped to the top of the tower,
7:42 am
where it reaches temperatures of more than 500 degrees celsius. the solved 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 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 gas. the researchers are working to optimize the recipe and further
7:43 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 to line it keeps on 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 solved recipe, its cost effectiveness and its properties. but there's another problem. salts are very corrosive. whichever thing at the thought or you event though,
7:44 am
there's still plenty of room to advance this technology in terms of the storage materials and click on the materials used for containers like as tanks on pipes and empty hops that they all bring their own challenges in which we have to investigate, it totally must be things like corrosion be and how the wheels you 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 move on to imports. 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 shift global power relations. this unassuming
7:45 am
container 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. 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 friction. please don't like industrial and collect 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,
7:46 am
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. 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 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 salt during the day. the project manager believes that conversion could spark a global green energy revolution. a base works a has a thought or a fake of been shut field, sir, because that and potentially every bit of electric power plant can be transformed
7:47 am
into a, more than so plants, a multitude 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 vs instead of a d. as in tina, a 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 grid. uh and the way in which we mean the grid on me and also do tucked under an investment instead of me. 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 role send a signal to the rest of the world. we state and she lane
7:48 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 paradise. but 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,
7:49 am
we also with the plastic chemicals you in the plastic. 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 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 had visible bite marks on them. when they say, look at these marks made by scientists say that people don't or the shock squirrels
7:50 am
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'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 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,
7:51 am
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, the, 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 items on what sort of equals the sea urchin fished out of the ocean, is now in the laboratory. it's contaminated to what do you see? it 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 the plastic or but christians are
7:52 am
a species that help keep the clips and coils clean the fun 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. i see gloves in other means. the 1st is weeping. we have to stop put on the brakes that can't go on like this and that you said, why don't they ever 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 that remote rio shingles, a tributary of the amazon river study, has shown that 80 percent of fresh water fish have micro plastics in their stomachs . whether that's also true for the parents that live in the rain forest here is on
7:53 am
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, to see why compared to speaking an atomic which became the answer is fairly simple. birds have a special voice box which let 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 controls to produce sound. the
7:54 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 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 localization 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 pirates can also learn how to imitate many other sounds and sequences of sounds, which is how they learn foreign languages like human speech. the
7:55 am
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
7:56 am
soon on tomorrow today. goodbye and show the,
7:57 am
the, the shift your god to life. and it did to, to you know, all the latest online trend. navigate your way through the digital jungle global perspective. we'll be your guide and show you what's possible. you decide what really message to you. shift in 15 minutes on the w. e co advocate raves amongst the seals of cape town. none of these done babies in the hall that yet having humans instead of cautious
7:58 am
with cell phones as the animals become that fear of you know, working with a lot of stakeholders and together we can take out the co africa being fussy minutes on dw, the d w, travel besides the t food. wow, fucking, let's go through. so when it comes to sustain dependency information and trend, this is alex texted on d. w. travel, you can have it. what about you, in your opinion, feel free to write your thoughts and the comments. hello guys. this is the 77 percent. the platform for advocacy issues and share ideas.
7:59 am
and you know, on this channel we are not or wait just happens, then it gets tough to young. people clearly have the solution. the beauty of this 77 percent, every weekend on dw cost about why does that mean? because now i'm leaving the new host to join us for an exciting explanation of everything in between. this is a video and audio production by d w. i hope video will tune in the
