she survived al schmidt's thanks to music. ah, he was the nazis favorite conductor, is morally degenerate to musicians under the swastika, a documentary about the sounds of power, inspiring story about survival of the home and go get the tennis. i was the only one. what lies english music in nazi germany watch now on youtube, d. w documentary, a kids that transforms wind into energy, a vacuum cleaner, that pulls c o. 2 out of the air and jones, the plan, treat digital innovations that combat climate change. our topic today on shift ah, to limit global warming to a maximum of 1.5 degrees celsius. greenhouse gas emissions must be nearly half by

2030. this is what the intergovernmental panel on climate change has recently reported. the consequences are huge, forest fires melting polar ice caps and devastating floods only by consistently avoiding using oil, gas and other fossil fuels. can we stop the trend or could digital innovations help humanity? some of them sound too good to be true, like the c o 2 vacuum cleaner. ah! near iceland capital reykjavik, a plant the actively removed c o. 2 from the ear has been operating since 2021. the technology behind it is cold direct here capture. each collection tanks extract the carbon dioxide with high tech filters and fans. first, the use heat to separate the carbon dioxide than it is mixed with water and injected deep into the earth. the air, the carbon cools and solidifies and no longer contributes to global warming. the

plant is the largest of its kind and can capture and bind $4000.00 tons of c o 2 per year. but it meets a lot of energy. iceland is night deal location because it has both hydro and u thermal resources. renewable energy is abundant and cheaper. it's the only sensible way to run the plant. we are committed to use only renewable energy, so we don't want to emit c o 2 while capturing c a to the plant we have in iceland its efficiency is higher than 90 percent. which means that for one come, we are capturing, we admit about 10 percent. so we are made about 100 kilo plane works 1st direct here capture plant went into operation in 2017 at the swiss site as you 2 was not stored in the ground but uses fertilizer in nearby greenhouses. this closes the

carbon cycle and prevents more carbon dioxide from entering the atmosphere. an impressive approach and it really works. but how much influence can it half on global warming? the plant on iceland can capture as much c o 2 in a year as 250 citizens in the u. s. consume. similar projects such as storing fear to under the ocean floor have only had limited success. seth, a j gambit of impure or college london. much older technologies with carbon capture storage, which they suck missio to out the atmosphere is such but actually capture carbon dioxide from combustion. fossil fuels and things like that. industrial manufacturing plants in coal, gas lighthouse stations, and the carbon capture and storage centers. she has been a bit of a disappointment in terms of the rate which has been able to be a pilot. the demonstrations in sales of industrial c o. 2 filtering plans can

therefore only stop the rising global warming to a small extent. so let's take a look at a completely natural method photosynthesis. plants grow using only light water and carbon dioxide forests are especially effective at removing c o 2 from the air, according to german climate experts, julia punk guts. from all the metro so called metro solutions forests are the ones that are probably have the largest potential. this is simply because it's large areas that potentially could be a forest that and forests have a rather high carbon density. so a lot of carbon per square meter. but every year around 15000000000 trees are cut down worldwide. this is for firewood or because the land is needed for agriculture, new roads, or settlements. grasslands and deserts continue to spret. this contributes to global warming. at the same time, climate change helps create even more grass lands. it's

a vicious circle in spain rangers are trying to stop this trend using drones. they want trees to grow here again. in only 2 days, they have spread around 500000 seats in india, the start up my roots. drones wants to use similar technology to plant 1000000000 trees by 2030. the seed copter plant trees from the air. the drones selectively spread seed falls over areas to plant new forests or to strengthen weaken forests. a drone can carry 10 kilos of seed falls each holding 4 to 5000 feet. this technology offers new opportunities for reforestation, says storage, petty, co founder of moderate drones. india is a bitty, bitty baby geography and button like deserves in boston. that, that ice in oregon are among girls in michigan. so there are many regions fair people are unable to reach for not many activities that are going on at present.

he's got that can be serious auditability with the for sewing the drone survey, the terrain afterwards, the seat capture continues to work. it monitors the seedlings from the air and the results are collected in a database to ensure healthy forest growth for once the miseries they can be done from specific algorithms. which can process this image to create that optimum. and we don't like understand optimum environmental parameters, but a maximum plan growth. so based on this information, we understand like which spots of the forest needs to be taken care where there is in the very low growth of the tree covered. and also, what is the optimal feedback configuration that needs to go in? artificial intelligence is decisive in monitoring the a for station efforts, but it can take up to 40 years for trees to grow and actually sequester c o 2.

according to green i t expert chris adams. they talk about planting a ridiculous amount of trees as in the area of india to meet one companies, carbon emissions, rather than just actually get to fossil fuels. so these can sometimes be end up being the unintended impact of being a distraction from much more important conversations. about the carbon ation. if we are to stop global warming, we cannot simply keep burning fossil fuels such as coal, oil, and gas. but where will our energy come from? then? could you imagine life without electricity? surely 800000000 people were wide. that's the reality. most of them live in sub saharan africa. fairly own in west africa is one of the least electrified countries in the world. only 23 percent of the population has reliable access to electricity . intelligence solar networks are set to change,

that solar panels have changed life and to come to a village in sierra leone. it is finally reliable power from renewable sources. a great improvement people here had a youth delay. because he that the for study feller, they at a youth and he visual freezer a fine, you don't call to be muffled full on life. in our mic alley doing possess, coma, the call fall to put a new a week, i need wednesday or cold. glad any cap will come by this community solar powered mini greece is designed to solve 2 problems at once. first, provide much needed access to electricity. second, reduce greenhouse gas emissions to renewable energy p. d. centralized energy system works in remote areas off the national power grid and

intelligent control systems are able to capture any superfluous energy. the power and company installed the microgrids from manager mohammed to leo county is a promising concept. is community 5 years down the road? it was completely dark, bought low, today we have electricity here for me going for, for the rest of the all. this is of a good, a viable option. our micro grits or local solar energy grids. really a global solution. we asked energy expert marie for bras are from kenya micro grid and not the be all and all and save up will at whatsoever. but they're in the integrity part of the electrification process in the, in the global south. like for example, the solution found by dr. m a thing in the indian state of rochester. he has installed solar panels both on his hospital and on the we farmland,

mozilla. i feel like i'm contributing to the needs of my village co put one for 220 megawatts and i am generating 5 megawatts here on my land regarding it. so i am contributing to 2 percent, every single my village is power needs. i feel good about the alarm. you regularly feed solar energy into the local power grid. individual projects which utilize a i can provide local relief. but other solutions are needed to meet the rising global demand for energy. that needs to be an understanding that is not centralized . read vices smarter. microgrids or boss is standalone solutions. it's really what's the best solution within each context. oh, the german company enter kite has an innovative and decentralized way of generating energy. it uses the power of the wind. there are no huge wind turbines, but instead

a mobile system. the portable system consists of only 3 main components, the stunned kite, the control lines, and the steering cabin. the kite is flown automatically with prevailing when conditions being taken into account they fly higher than the tops of existing wind turbines. i noticed in enter, kate uses the wind up high, where it blew strongly and consistently above to these wind turbines. high uses high technology, kate systems that are controlled from the ground and transmit the wind power via the lines to a generator on the ground. he's either a, get an art for you, but hug the kites, are designed to generate twice the power of conventional wind turbines. a decline only the small turbine bleed tips are actually effective. the exam is we've reduced our system to that. it looks yeah. and replaced the stability of

steel and concrete with a very reliable control system. they told me which i didn't get to for that thing. on the costs for solar and wind energy and for batteries are thinking they're down 85 percent since 2010. but time is running out. we must act now and make more use of modern energy technologies. the i p. c. c has warned that we have only 3 years to reverse the trend in greenhouse gas emissions. there are innovations, however, the technologies we have seen today are only a small part of the solution. the theo to vacuum cleaner won't help if we still burn oil and gas. what have you done to tech climate change and which technologies do you find the most promising? tell us on youtube already w dot. come by and see you next time. ah

ah, i tried several times. i went to one on 6 times to greece in his throat. i have just land line from 500 to 600. you currently more people than ever on the move worldwide in such a better life. you know, this is a very difficult journey. and 13 family control is very hard. they be today's date or audio story. find out about some months story. info, migrant, reliable news for migrant. granted, they may be german w. this award winning offer is available worldwide. german has never been simpler

german to go. remembering benjamin ferris, which are film on the d. w documentary, youtube channel, he was the chief prosecutor at the nuremberg trials. thanks to him. nazi mass murderers were taken to court after the end of the 2nd world. a man tireless in his efforts to stand up for justice around the world. benjamin ferren chief. now on dw documentary, ah, many of those who come to see louis can find a home any place else. from here you get the best view of cali, but the slum and its residents are not part of the picture from any columbia cielo a is synonymous with crime and violence. a joke, we really introduce myself and said hi,

i'm christian. i come from seal away and then they all said, oh, but we'll go. it's really dangerous for them, but it was easy, mo, now the ceilings are fighting back by telling their own story. oh, good. not bad that. yeah, i can go, you know, bedroom. whenever you get better media or better, bobby. yeah. if i see, i think we're gonna though i've been bought available, you're not there yet. it's unusual to see christie and oh, yes. without a spray can in his hand, the alias of the graffiti artist from one of columbia's most notorious slums. is apple seen away? apple means mountain and catch you up. see, loy is the hill that he calls home for the i what i oh really like what you see from the outside as oregon is gone or if it where the people are afraid to come into our neighborhood because they don't know how we do more drug marios.
