the names of migrants on the african continental europe, deadly migration policy starts february 15th on dw, the using gravity to enable energy storage. how does that work? the, how it's tiny wounds can have devastating consequences. the and c weight is on the menu. initially you still prestone the

task once they make for a strange looking site. she's the o dean and her father miguel. are all girls see read, collect to have on the coast of tele, demand describing especially for special types of ok. she's that level again. i'm to family mainly collect caught you, you, you enjoyed long ago by the indigenous mckreetee people nowadays it's even cost of cruising. the you give them cable is a super feed. we believe that the food of the future is in the c. m. ok. when the weather conditions allow, she's a low gain on her husbands go out together. see we'd it's a dangerous undertaking of

the seller's family has lived from the sea for as long as she can. remember. i always have to assess how far i can venture in at the moment the will to level is a bit lower, but the time always having to fight against the force of the sea. it's always risky . but we have to walk today to collect some leaves for an order from one of julie's top restaurants. collecting and selling c. we does all likelihood. yes. even though it's hard what we enjoy it. it's good luck. it's an upload to calais, move a about 260 kilometers south of santiago, chile. this is why she's the on top family.

most people here live from fishing or collecting. see we'd several among the 70000 dogs who do this along. chillies loan coast, the seaweed processing talents with such a couple of cheap i women. most of the see read is exported to china. originally, it was chinese investors. he wanted to build the factory head you know, so why should we leave the spot to the chinese? why don't we do it yourselves? when i say that, that's why we felt this 535 years ago and created jobs because the demand for culture you jo, keeps rising. we need more capacity. people who are convinced of how he is a food with a few and she's selling is delighted. she's been contracted to supply a world class restaurants in santiago to to me today,

she has to be delivered to the usa. happens to be to least most famous shots, the it's a race on a to supplies such a renowned restaurant. people who have never reach now do you like this might say i don't see tests. i don't like the texture on the flavor video, but the way we prepare it has many people says perhaps the most delicious speed they've ever tasted. assets russo on the way to design new products, like the snacks for children made from all of the flour. roberto labels mondanca is a nutritionist at the university of chilly. he believes that c reed could revolutionize the street mock, attempting to capture you. your algae in particular is multimedia

boasting with important nutrients. it's also thought to have healing properties that are meant the inseparable regions of chile. people can cmc reading quite traditional ways. but we see a lot about the potential to a person instead of getting we'll have to do with the help of new technologies like 3 d printing, we can turn it into attractive shapes and increases popularity comes out. she's ella and her father at times get the bunches of caught you. you see we but they played out to dry the noun, ready for the processing. most of the l. d is flushed up by the see fairly, harvest the small amount from the see that because they know how t c we does as an absorber of c r take care of on the beach they. and as i got the rows of set up wouldn't chunks. this is why they store

the see me to prepare it for selling it the like to market dollars. family run a stall that every day her father takes the opportunity to caused his fishing that somebody can't live on the weight alone. um there's always something left over to sell from the funds and costs even a curious the line doesn't die without my life by the sea, and i wouldn't trade it for anything else. i liked the simple, quiet life. we have what we need to know as much as thoughts is thanks to the sea we, i'm the prospect so toughest. the

between the company can seem homeless enough. but the way if bacteria enter all bloodstream is the result the immune system steps in. however, if this reacts, sit via inflammatory response is triggered, flooding the body with inflammatory messages and enabling the pathogens to spread. the results can be organ failure even death. that's what makes steps so dangerous. a minor injury may a cuts on his finger, lots of steps to send almost costco given, telling his life. he lost both arms and legs. custody is a target. there are days when i want to go into the woods and scream, my head also likely to happen. don't happen. often of course he's done. now he just wants to get his old life box as much of it as he can. he says, open board. let your feet make contact with the floor as much as possible. get

yourself into a good starting position with sound good body tension. yeah. before you stand up, review all the important points in your head. how many websites will help you get up without using too much energy? and so operating an electric wheelchair, it works well. that deal could still alive as a small miracle. he was in an induced coma for 16 days and underwent 8 soldiers. for months it was i'm certain whether he would survive. if you now attend sessions at this clinic, to train his extremely weakened body. not mine, okay. but when i arrived here after my operation, my body was so weak and my muscle so atrophied. i could only look my head and say, you don't mind call team content to see i'm come. the 1st thing i had to do was get fit again. should we build my body off to rebuild my muscles on so that i could do

basic things of everyday life? again, seems like brushing my teeth for just getting out of bed and into my wheelchair. what have you out of state also that's from that in the most to the full started so innocently was here. so that's what happened was i caught myself in an old here mattress and the seller. and this one, it was a very, very small come to my left index finger, which became infected and send it out. this comes, it turned into a strip to call co infection, which ultimately triggered subsets as far back. and you can see the small, small cot here, and that then developed into a blister over night, like going up the other end because that's where he's suffered septic shock. he has to be placed in an induced coma during the infection. his body diverted most of his oxygen to his vital organs, the brain, the halt, and the long's on this. so because of the large parts of both his arms and legs

didn't receive enough blood peanuts, and this is what ultimately led to him needing the amputation. asked what he had to have. it was a really serious case and he is actually off. i professor clients among the oaks, the attending physician at the rehabilitation clinic. his major concern early on was that the residual limbs and the skin protecting them, feel properly only then what is it possible for guilt to be fitted with pros, dc's substance is one of the most common diseases worldwide affecting around $50000000.00 people every year. most deaths could be avoided with the correct diagnosis and appropriate treatment. and for the last, i knew that i was completely unaware of what steps this is and what it can lead to in the end that somebody will help me said was that i've only learned recently her bad senses can be reached. and mine is epsis was getting kind of the fluid in most cases, at least the desk because it does not recognize properly. and so having obvious, in that respect,

i was very lucky to survive that and i just still be sitting here today. so if can come get therapist costs schmidt doesn't just give him practical tips. he's a cheerleader too. he knew gail could need both psychological and physical help. that's very nice. well done. chip, i didn't help. so that worked out well. yeah. so do that on your own lineup. of happy profit fits a steals good and it was no pressure points, no pain. nice. every step takes enormous effort, both physically and mentally. one day deal been telling hopes to be able to work again before the steps this he was a marketing team leader out of medium sized company. space to get to work is a very important part of my life is integral. let's go ahead and talk to my old life. is this part of my new like to? i'm 40 years old and 50. i couldn't imagine just sitting at home from now on and

taking early retirement. and so i feel strange again just feels wrong. coolants on, on the stops often assign i one to buy, go if you did it, so that was the feel free to didn't crush your hand today. no standing will king deal wants to reclaim as much of his old life as possible to spare and doubts all his constant companions escaped. feed it another day, i have many entered demons, new day to go to that i couldn't find. there are days when i could just scream at the wall of mine and beat us as everyone can imagine. what it's like on this day that there are certain questions i simply shouldn't ask myself right now. and the system must be the fargo questions like why me, why not someone else on the above all is the question. who's to blame naturally? defend or despite these are the 2 most important questions that i try to ignore all

the time because there is no answer to them and they don't get me anywhere either on the self. and so i definitely, or after 6 months, feel been telling is allowed to leave the clinic. he is happy to be back in his home and be offended and tries to apply which he has lunch during his rehabilitation. fitness gates seem to be a lot as possible. a loss is no longer possible. and for me to be a lot simply has to be planned with the help of family members when it starts with getting one shot at the fridge. in the fall, i have to use my wheelchair to get food stuff and then be able to get to top. there's difficulties in the morning too, so using toothpaste, one, brushing my teeth. the tooth brush can't be too far away so that i can still reach it. this is part of everyday life, a fit. some of what i taken for granted has suddenly become an obstacle then. and some things are just impossible. dlc within telling doesn't give off. if something doesn't work right away. he sees it all as

a set of physical challenges. something he used to see counts when he was younger, which he had many good. well i grew up on the skis. i used to ski or slope as much as possible and i mean really off slow side um, replaced in glenn the in the back country, the steeper the better the renewal limits before it got can limit for yeah. and i was also a passionate dancer. and so my wife was my dance partner, of course, so so convincing them i'm trying to instill this attitude into my children. but of course that will be a bit more difficult to do in the future. like to the site, the tops of his life are returning to normal is due mainly to his wife alexandra. she and georg have been married for 12 years. when mix of them you learn to adapt to the situation. it's like a movie and it didn't feel like our life. it's only now that the 4 of us are back at home that every day life is slowly crept back in. yeah. and what's different

driving the kids to where they need to go in the morning by myself. that was a task we used to share up on that, that i have to make sure before i leave the house. that leaves georg a coffee cup with a straw in it, and then i wash an apple for him to eat for the next time. she will never forget the 1st time she visited her husband and the hospital, off to his amputation with the 2 children. so a long time the adviser. okay. we came into the room. yeah. so the 1st thing saturday night instead was dead where your hands. and i said i told you remember, yeah, but then very soon it was just like always we all staged erased with the wheelchair . getting on ran alongside me. leah pulled the little one was sitting on gaylon's lap. so yes, it was just like always. well, gail conduct exam dressed every coffee together in the late afternoon after she's come home from work. they talk about the traumatic experiences of the last few

months and what has given them strength significant, and so important to have a family, a ready to for emotional support is going to hum my children and my wife have been such a comfort for me. i don't think i would have had the will and the motivation to work so hard on myself for such a long time with items one will help them get so i buy them gills. high tech pros, dc's costs thousands of years. the paid full mainly by his health insurance. some a diety is an important principle in german society. the healthy pay for the sick, the rich well, the poor. everyone is entitled to the same medical treatment. today, orthopedist or slot ski is given guilt. a new sense of pros, dc's, but i've got your new feet with me. said they don't feel natural that's for a job. i get it. i don't know if it would be like a lot of times i just got the sounds i said, and at 1st it feels good to get a bit more support and it helps cool. as soon as most of you now,

you don't have so much play in the many more me, i'm great. you leaned back, but then adjusted all on your own guilt of intending is making progress. but he's eager for things to improve even more quickly. escaped by the one of the things we'll continue to progress is if one improve doesn't work. there's always another good just to finish on finding that new approach becomes the important thing to do. the most important thing is to keep going to keep out to it. a gale griffin telling has already recaptured aspects of his full of a knife. such a spirit of clothes. it's different than it was back then before his surgeries. the way so many things off since that fateful day when he suffered what seemed like a minor injury in the sense the

is the sun doesn't shine every day, and the winds doesn't constantly blow. how then can renewable energy is helped me growing global demands without batteries to store supp his energy? it's not easy, particularly in countries without too reliable supplying there all. however, some price ideas out that this is a battery. it might not look like one, but this wait here, stores the energy it took to move it up here. when it's released, it can power this light the when we produce more electricity than we need. like in the middle of the day when there's lots of solar energy, we can use that energy to lift a heavy weight. it just sits there until we lower it again. the motor becomes

a generator and feeds electricity back into the grid. this technology could be a good way to cut c o 2 emissions. we need a lot of renewable energy and places to store it. with ever more renewable energy, we'll need more reliable, short and long term storage that could be for hours, days, weeks, or even months pumped to storage. hydro power is great for this. it's been around for more than a century and still makes up over 95 percent of our storage capacity. water is pumped from a lower to a higher risk of water when there is an energy so or plus and slows down through the turbines to supply energy when it's needed. pumped hydro is tried and tested, but it needs a lot of construction work and disrupts natural habitats. and it's not easily scalable. but the gravity principle is we basically mirror that same process, but instead of wire for one of our solutions,

we use blocks. that's robert per coney, the co founder of energy volt, the biggest gravity energy storage developer here is essentially, depending on the size of the system, can be up to thousands of air per systems. back in 2020 energy vault build this prototype in switzerland, 6 crane stats. the concrete blocks up to a height of 70 meters. the prototype, prove the concept works, but it also received criticism that the structure didn't comply with building codes and might not with standing stream, whether so energy vaults came up with this gravity, battery building thousands of blocks are lift your door, lowered and then stored horizontally as seen here, the 1st battery of this kind went into operation in route on china. gets taller than the great pyramid of diesel and has more than $3500.00 blocks weighing $25.00 tons each. they were made on site from excavated soil, but the company says they could also be made out of waste materials such as coal,

ash, or wind turbine planes. it's 100 megawatt hours so that you can think that equivalent to powering about $35000.00 homes. but only for 2 or 3 hours, the company plans to build for gigawatt hours of gravity, batteries for china, or 40 times this one. gravity batteries could in theory, lift a weight and keep it up for 60 years. the motors might need replacing, but the weights in stored energy would remain in place. the. the biggest drawback is the cost. that's evelina started coolant for senior research associate at bloomberg. any eps energy storage team. it recently published a study comparing several long duration energy storage solutions. and what we found is that gravity, batteries have a higher average costs and higher costs range from all the other long duration technologies. one of the reasons that they have

a very high cost is because we have very low energy density. so you need sort of larger infrastructure in order to get to the same uh, in order to store the same energy as you would need for lithium ion battery. for example. the gravity battery and redone stores the same amount of energy as this lithium ion battery. but the gravity battery needs much more space and building materials. so the initial cost is higher. it also it loses out in other ways. storage operators earn their money by discharging the g and selling it for more than they paid chemical storage. like lithium ion can react in milli seconds to market needs, which allows for a lot of quick profit taking the so gravity, battery storage is more expensive. right now it costs twice as much as lithium ion technology. put developers like energy vault,

say that's not really a barrier because they have such a long lifetime. so 5060 years, which is considerably higher compared to machine miles. so they make names on a level ice cost of storage over the duration of the project. life time is, is lower than the startup costs of gravity. batteries are even down over their service by thanks to low maintenance costs. that might make them competitive in the long run. let's go underground. we looked at a $1500.00 underground coal mines and from these coal mines we, we estimate the capacity of or 70 total was our storage. 70 caroline hours of energy is huge. it's what the entire world needs in a day, and it's 700000 times the capacity of this. and that's just a deep cold mind shots. a band in middle mines could also work the ideas

to have a small number of very heavy weights. moving up and down the empty shaft. installation costs could be fairly low. underground mines have the road access. they have transmission lines into the mind. so you can use that energy could then be stored when it's really cheap and used when it's much more expensive, making it a profitable solution, whether it's for hours or months. we'll only know if this system works as planned once it's built. there were some other rather bold ideas for designing efficient gravity batteries, like sinking a giant kristen into the ground and raising it and lowering it with the water underneath. the idea has been around for a few years, but it hasn't gone to the pilot stage yet, or putting weights on wagons on rails, which would travel up and down the mountains. that ideas over 10 years old, but hasn't gone anywhere yet. energy evolved is planning an updated version which

looks a bit like a ski lift with weight. they say this system could be more efficient than the standalone gravity. batteries they're making now. and soon, gravity batteries might be installed and skyscrapers energy volt plans to do just that. in collaboration with an engineering company, gravity energy storage is still in its infancy. it can compete with a scale and low cost of lithium ion storage. but it doesn't have to, since gravity storage is intended for longer term storage of 6 hours or more. so gravity energy might become one of many options to store energy long term. but you probably won't see lots of these popping up any time soon. news
