way and dream vacation to the human they is change their mind. we will now say the way starts february 14th on dw, using gravity to enable energy storage. how does that work? the how it tiny wounds can have devastating consequences. the and c weight is on demand in cities tell prestone the

task once they make for a strange looking site. she's the o dean on to a thought. let me go around. carol's, see, we'd collect his hair on the coast of chile, the mom describing, especially for special types of ok. she's that low gain on test family, mainly collect caught you, you enjoy the lonely guy by the indigenous mckreetee people. nowadays it's even cost of cruising. the given cable is a super feed. we believe that the food of the future is in the sea and okay, when as a weather conditions allows, she's a low gain on her husband's go out to gather c 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 water 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 to data collecting leaves for an order from one of chiles, 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 flashy seller, and most people here live from fishing

or collecting. see we'd several among the $70000.00 to do this along kelly's loan coast. the seaweed processing talent with some top luxury by women. most of the see read is exposed to, to china. originally it was chinese investors. he wanted to build the factory, head milestones. why should we leave the sparks, the chinese? why don't we do it so? so that's why we built this factory 5 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 a is delighted she's been contracted to supply a well express. johnson santiago to me today she

has to be delivered to the you'll say happens to be choose most famous shots. the, it's a race on a to supply such a renowned restaurant. one of the people who you've never reach. now do you like this might say i don't see tests. i don't like the texture on the flavor. but the way we parent him, many people says perhaps the most delicious speed they've ever tasted. 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 see, read could revolutionize the street market some teach culture you,

your algorithm, 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 lots of other potential to a person instead of getting, we'll have to help putting new technologies like 3 d printing. we can turn it into attractive shapes and increases popularity comes out. she's ella and her father a times get a bunch of caught you. you see we but they played out to dry the noun, ready for the processing. most of the audi sports step by the see they only 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 like out the roads have set up wouldn't chunks. this is why they

store the see me to prepare it for selling the like to market. just alice family run a store every day. her father takes the opportunity to cost is fishing, that the family can't live on c weight alone. um that's always something left over to sell from the funds and costs even a curious the line doesn't get without this. i mean, i love 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 how much of the box 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 tickets, selecting 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 off from life that you happen. happen often know where he's done. now he just wants to get his old life back as much of it as he can fix is open board going let your feet make contact to the floor as much as possible

. get yourself into a good starting position, but it's not good body tension. yeah. before you stand up, review all the important points in your head. how many of ice will help you get up without using too much energy until 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 uncertain whether he would survive. he 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 lift my head is this you don't mind cop team content to see i'm come. the 1st thing i had to do was get fit again, should rebuild 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 then to my wheelchair . what have you out of state awesome. that's from that in the low store to the full started so innocently was here. that's what happened was i caught myself in an old here mattress and the seller. um this one, it was a very, very small cottage on my left index finger, which became infected and send it out a comp and turned into a skeptical co infection which ultimately triggered subsets as well that i can, you can see the small, small cup here that then developed into a blister over night, like going up closet, and because the inspection was caused by mouse droppings on the mattress. soon gale was in severe pain, had a fever and shortness of breath to doctors. told him the infection was homeless. the august the volume because he was finally admitted to a hospital where he suffered septic shock. he had to be placed in and induced coma

during the infection. his body diverted most of his oxygen to his vital organs, the brain, the hot and the lungs. it's done is 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. so to have to have it was a really serious case and he is actually off. i, professor kind, somebody chokes 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 guild 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 it for the often long plus and effects. as i was completely unaware of what steps this is more that can lead to in the end

that somebody will help me. i've only learned recently how bad such as can be reached and a zip is always getting kind of in most cases, at least the desk because it does not recognize properly. and so had obvious in that respect, i was very lucky to survive that and just to be sitting here today that can come get therapist cost schmidt doesn't just give him practical tips. he's a cheerleader too. he knew guilt would need both psychological and physical help. that's very nice. well done, chip. i didn't help not work that well. yes, you do that on your own lineup. of happy pockets. it feels good and it was on low pressure points. no pain as nice. every step takes enormous effort, both physically and mentally one day deal, then telling hopes to be able to work again before the steps this he was

a marketing team leader out of medium sized company, consisting of a work is a very important part of my life. is integral, let's go ahead and talk to my old life as good as part of my new life to i'm 40 years old and 50. i couldn't imagine just sitting at home from now on and taking early retirement. and it's, i feel strange again just feels wrong. coolants on, on the stops off of the sign i one to buy, go and so you did it so that was the so if we 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 feeling you know that i have many entered demons, new data about that i couldn't find that are these when i could just scream at the wall of mine beat us if everyone can imagine what it's like on this day that there are certain questions i simply shouldn't ask myself right now,

and this has to must be the following questions like, why me, why, 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 shelf. and so i definitely off to 6 months, feel good in telling is allowed to leave the clinic. he is happy to be back in his home and benefit and tries to apply what she has lunch during his rehabilitation fitness. kate, seen a lot as possible as a whole lot is no longer possible. there was a lot simply has to be plans with the help of family members when it starts with getting one church at the fridge farm. i have to use my wheelchair to get food stuff and then be able to get the top 10. there's difficulties in the morning to sort of using toothpaste when 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. i've said some of

what i taken for granted has suddenly become an obstacle then. and some things are just impossible. dlc then telling doesn't give off. if something doesn't work right away. she sees it all as a set of physical challenges. something he used to see counts when he was younger, which he had been good while i grew up on the skis. i used to ski or slope as much as possible and i mean really off slow guides from that place in glen, the in the back country, the steeper, the better the renewal limits before it can limit. and i was also a passionate dancer. and so my wife was my dance partner, of course, so, so i'm going to send them and 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. i like the fact that pops 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 has 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. and then i have to make sure before i leave the house that lift gate or the coffee cup with a straw in it. and that was 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 kindly advised new york, and we came in to get young through the 1st thing saturday night instead was god where your hands. and i said, i told you remember, yeah, but on but then very soon it was just like always under the we all stage the race with the wheelchair getting on ran alongside me. lia pulled the little one was

sitting on gail's lap. so yes, it was just like always gail control exam drug share a 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. so important to have a family are ready to for emotional support. so how my children and my wife have been such a comfort for me. i don't think i would have had the will. the motivation to work so hard on myself for such a long time without them to own will hold on it. so all bible gale oaks high tech prostheses cost thousands of years. the paid full mainly by his health insurance. solidarity is an important principle in german society. the healthy pay for the sick, the rich will, the poor. everyone is entitled to the same medical treatment. today, orthopedist or slot sky is given guilt. a new sense of pros,

dc's. so but i've got your new feet with me and said they don't feel natural. that's for a job. i get it on all week. so i just want to finalize this couple times. i said, and at 1st it feels good to get a bit more support and it helps cool submission of you now. you don't have so much play in the many more yeah, great. leaned back but then adjusted all on your own guilt of intending is making progress, but she's eager for things to improve even more quickly to escape by the on the so that things will continue to progress as if one approve doesn't work. there's always another good just to finish and finding that new approach becomes the important thing to do. the most important thing is to keep going to keep out. a deal been telling has already recaptured aspects of has full of

a knife such as ski and of course it's different than it was. but then before his surgery is the way so many things are since that fateful day when he suffered what seemed like a minor injury in the sense the is the son doesn't showing every day on the winds, doesn't constantly blow. how then can renewable energy helped me growing global demands without batteries, to store surplus 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's an energy surplus 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 water for one of our solutions, we use lots that's robert per coney, the co founder of energy volt, the biggest gravity energy storage developer here is essentially dependent on the size of the system can be up to thousands of them for systems back in 2020 energy vault build this prototype in switzerland. 6 cranes stacked 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 the energy vault came up with this gravity, battery building thousands of blocks are lifted or lowered and then stored horizontally as seen here, the 1st battery of this kind went into operation in rude dung,

china. it's taller than the great pyramid of dfcs and has more than $3500.00 blocks bring $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 at 100 megawatt hour 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 4 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, still a coupon 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 has a higher average cost 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 the same in order to store the same energy as you would need for lithium ion battery. for example, the gravity battery and moved on 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 looses 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 let's see, miles. so they make names on a level ice cost of storage over the duration of the project lifetime is, is lower than the high 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 70 total. what's 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 chance a band in metal mines could also work the ideas to have a small number of very heavy weight. moving up and down the empty shaft. installation costs could be fairly low on the ground, binds 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 plant and 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 the 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.
