is that then leaders can't construct or more than just buildings. he is the son of jewish holocaust survivors. working that i was able to bill to just says in berlin. his architecture is a celebration of democracy and peace and architect of emotions. daniel starts december 25th on d w o . hope you have a heart of a sokulaf economy. it's when nothing gets thrown away and the most is made of the available resources on a farm in been in. they've been following this practice for 40 years. welcome to

a new episode of equal africa, mine in eas, sondra, queen of you, coming to from compiler, here in uganda. and the one wall come from me, chris, the lone synagogue steve nigeria. sondra up. i'll show this week is also a little alike. but secular economy, all the pieces fit together perfectly on today's show. how people in madagascar a cookie with grass all through them is conducting research on green steel. and how solar energy is being harvested on the softness of reservoirs. you're out in the fields and you hear a loud throbbing, ang, gin and smell the stench of diesel. is that really progress? well, anyone who wants to trade in the iraq sport tractor usually has to buy

a diesel pod vehicle. but there are more environmentally friendly alternatives as this project in run that shows ah, it's just a normal working day for members of the do. cora cooperative, near kigali. the villages until the fields by hand. the many help as a busy for weeks chicago shock cultivating a large area like this using just hose is difficult to humans. we do it because there's no other options. i his, i, if we had a cultivation machine, congo, we could produce more with less effort. there are a few tractors around, but often they're older vehicles that were no longer wanted in europe. they tend to be noisy and dirty. diesel is also not always available and rise and fuel costs means that they are often economically viable. from the outside solution looks remarkably similar, a to point to tom tract of the 27 was car engine,

but the motor is electrically palate. a german comic a developed this detractor, prototype along with the university of to galli, and the g. i said, german development agency, that son convert a dies or tractor into an electric tractor. you see, we just replace a diesel engine with an electric motor and put the battery on top of that. and there you see the swapping desk, you see the 2nd battery on, on this desk. and when you come in here you can move forth and back down. then with that you can release the battery and show it back and put the full battery on the truckload sofa can then resume working. the batteries are charged using solar energy. solar electricity isn't just clean. it can also be used off great. only half of one days actually connected to the grid, burnett, mackenzie, queen,

and his team from the diversity for one day, a working on making the batteries more robust so that the tractor consume go to work on the dusty sunbaked fields. rhonda needs it for other quarter mechanization to beat user friendly. busy because of, for reducing the in depletion, fatherly it to maximize the productivity. agricultural product is rwanda has to increase its agricultural productivity to help feed it's rapidly growing population long periods of drought linked to climate change or increase the pressure to make farming more effective and sustainable. the fact that the e tractor is intended for use and more remote areas is a particular challenge for the developers in the team of v w engineer. pull the laggy. the main point is to make an electric tractor as

simple and easy as possible because it should be easy to operate. and the other thing here says, when it is simple and easy to maintain and to repair, to make the tractor suitable for working rwandan fields, the prototype has to be further improved. vacuum. so the team of developers traveled through the country speaking to potential future uses were root, or wherever they want to import how the tractor to be designed and what will be the task of about the dose factor and we or so on to, to taking into account to some other activities that can be done by that tractor and ploughing isn't the only job the tractor should be able to tackle here in rwanda, productivity and funding areas can only be increased if other farming jobs can be

automated, as well as the develop as a test and whether it can be harnessed to help irrigate the crops. today we are testing the font being operated on an electric tractor. so you can use it for cultivation using your or your plow that could be a disk plow. then you can also hook up a planter to roll for a plant i can pu, than you can use it for planting. and then other tasks that we can use, the instructor is for spraying. that is your crop protection for pests and diseases . all tasks that have been carried out manually up to now. many farmers cannot imagine that the e tractor is going to be ready any time soon. but they do realize what a difference of might me if you're young, if there really is such a tractor and it's available to us, it will be seen as a liberator for farmers. because we won't have to work so hard to get our work done . the each chapter is going to be ruled out in 2024. the idea is that it will be

purchased by an entire village rather than an individual farmer managed by cooperative. the vehicle will make a lot of taxes easier. so don't forget to blame. we've just seen how full of panels help run electric tractors in rhonda, but the sun can be harnessed on a much larger scale. even if the sun doesn't shine as much in europe. more and more countries, there are investing in solar pox. that is right, crease in 2021 solar energy production in the rope in union rolls by 19 percent. but that's nowhere near enough to reach your slime. it goes funding space for solar pucks in densely populated countries isn't always easy. the one business man in portugal has come up with a brilliant idea. here on portugal, al cave are reservoir. europe's biggest floating solar park covers the equivalent

of 6 football pitches. it can only be reached by a short boat trip, one on which miguel patina has been giving many interviews. it's taken 7 years with the energy company team to bring the 5 megawatt to photovoltaic array to completion. is working. and if for you in the throes by everybody, what is the potential that we have here on our hands? this is natalie selling energy. that is the my purpose. oh, our purpose in my theme is that 5th, things that are sustainable are ever risen and used the least resources are the minimum resources is possible. the energy company is investing heavily in renewable energy. solar currently only makes up 6 percent of the countries energy mix, bought an advantage of floating sober parks is that they occupy spaces that could

not be used otherwise. and being on water energy production is more efficient than on land. as the panels don't heat up as much and are likely to last longer, the panels must be kept clean to produce as much energy as possible. that job requires a good sense of balance and patience. but eventually, robotic cleaners will take over the task. 1500 local households receive clean energy from the system that's been fine. and mainly by portugal, state energy provider adp rocco, for their whole rock of surfaces that can be used. and her skill realty, yes, is just as they are more power. of course, respecting while the environmental conditions that you have, it's scalable. it's complementary to the other sources is not an alternative. it's a complement period. so it's the solution to go further. and 3 chris proof of her

changing and the colonizing the array connects to the grid by the hydro power plant in the damn excess solar energy can be stored or used to pump water back into the reservoir to generate hydro, electric power, the 12000 panels and 25000 floaters on the al, give our reservoir, have been tested to withstand water, wind, and rough waves. the floaters are made in this factory in cash that yet in spain's alcantur region. one carlos at a mandate is one of the engineers behind the technology. they're made from recycle to poly thin plastic and they're selling like hot cakes. and i'm a for bagging them, prefer yogurt. i feel much better than what we're just a little company, but we grew ever recent years ago. now we are 20 people who work on the design, the commercial side and engineering. if anavia yolanda,

they're both younger than it was the website, blunt liberals and on the production site, we're talking about $30.00 to $40.00 workers that weren't that are hardon must reduce, understand, does plan, but it's a real success story. fernandez and immune groupons who set up the company together in 2008. they are now adapting their floaters to other environments such as sewage plants or agriculture waste facilities. the alcohol array covers less than one percent of europe's largest artificial lake. and 80 p is planning a much bigger floating array on the lake as part of portugal to push for 100 percent renewable energy by 2030 these towers events mark in portugal. and the example to the world as well, with our 1st project in the hydro, them, and then placed the benchmark in all utilities in the world, especially in asia, asia. they were very keen on these projects because they have large dams and they

also are important to and energy problem to, to solve. and they will ramp up her explanation, especially with these type of projects in so we can expect to see many more fees floating solar parks around the world in future. from floating ceremonies, we move to something heavy and extremely energy intensive to make still every year in europe. more than 150000000 tons of still are produced. emitted massive amounts of carbon dioxide for each ton of still $1.00 tons of community excite. i released, but the still industry has an ambitious goal to become climate neutral by 2050. now research has kicked into high gear. here is an example from sweden. it takes a lot of energy to make steele temperature as well over a 1000 degrees celsius. i needed cooking coal is generally used to produce the heat

. and while that's bad for the climate, it's still commonly practiced in the industry. like here at sweden's s s r b steel works, we actually feel that the glass furnace with iron or pellets and that is iron outside. and then we make it in layers when cooking cold. and then we, we blowing hot air in for the last furnace and the whole mel the iron and asked me since we get theo do, according to the world steel association, steel production accounts for more than 7 percent of all global carbon dioxide emissions. in order to produce steel more sustainably, ss arby has started a pilot project in collaboration with a mining company and the swedish energy provider button file. we realized that we might have a chance now to out compete the direct use of fossil fuels in industry. with this

electricity coming from fossil resources, the new plant works with hydrogen generated from renewable sources. hebrews to stands for hydrogen breakthrough iron making technology. instead of using coal, we can use hydrogen to lose reduction. so hydrogen gas combines with the oxygen in i, nor. and we get, i, and we get water weapons that what we're per can be condensed recirculate reducing the process so that we really solve the root cause of a carbon dioxide emission from steel making. he bridge started operations a little more than a year ago, and tests are still ongoing. only a few 100 tons of green steel have been produced so far. we know, working on the scale up of this technology to make the 1st plan to what we call the

demonstration plant, with a capacity a 1350000 tons a year. and we hope to have that on stream by 2026, attempting to go green is worth the effort for isabella, se steel experts because in sweden, resources are still relatively cheap compared to those in other european countries, such as germany. lunch. when is your contest you? it was it widely known that sweden has an abundance of hydro. electric power to met is one major factors that we shockey, but the amount of steel produced there is also significantly less so it may be a 10th of what germany produces, for instance, is killing us like c into on to in sweden also has huge or deposits so or is no longer mind here in germany kind of lies nancy. so the conditions here are completely different onslaught. nevertheless, a number of companies such as automobile manufacturers are interested in the technology, especially in light of the rising pressure on manufacturers to produce more climate

friendly steel production is constantly being modified to both lower costs and increased volume. because the demand for steel is high, and that includes for building wind turbines and solar parks, which will produce the energy needed for the steel industry to really become green lake. still, you have to reach temperatures of at least 1000 degrees celsius. a delicious point, 4 or 4, however, only needs what is to be briefly heated to 100 degrees and then start constantly. but too many people in africa still cook using fire? no students in madagascar, i'm doing their beat and how formed an alternative? let's have a lic ah, 30 years ago a forest stood on this now barren landscape, just 10 percent of the natural forest cover remains in madagascar. deforestation is

destroying the habitat of many species that are indigenous to the island. huge numbers of trees are also burned down to make room for farmland. the practices especially prevalent on the southern part of the island country and evermore trees are cut down to make charcoal. ready many of the islands residents cook on open fire grills, but there is an alternative to environmentally damaging charcoal sustainable pellets made from a grass that grows all over the island in the nathan of vanilla, this kind of grass is common here even what trees and grass we still have just get senselessly burned when thinking about the problem, we thought, why not turn the grass that the people burn into pellets? paulette. once the grass is dried, it's cut, compacted and formed into small pellets. the local association arch pair came up

with the idea. they are committed to renewable energy sources. together with german students, they developed a small energy efficient cooking stove. the project receive support from the university of applied sciences into seldorf. arch bear hopes to bring both products to the market as soon as possible. and we are planning to make like a massive mass production of the set pallets. and at the same time must production of these the specific stove that these are not. these are compatible with disabilities. they intend to sell the grass based pellets for 30 by percent less than charcoal. 35 kilograms would cost 3 years. instead of 4 stove, they designed his plan for mass production here and under layman cokie, they raised money for the project by a crowd funding and from german donors. grass

from making pellets is also being planted. the project succeeds at 2 objectives, creating jobs while slowing down the deforestation of madagascar. and how about you? if you are also doing your bit, tell us about is visit our website. oh, send us a tweet. hash tag doing your base. we share your stories. less deforestation and more jobs solving to problems. it was in keeping with the aims of a circular economy that we mentioned. art, this thoughts over shill, exactly sandra and add this some guy farming benign. they've been using this proxies since, but 198 is. but just how did they do it?

oh, good. everything's part of one big cycle and the song guy and casual center, which was founded nearly 40 years ago by father godfrey exam with joe, a man with a mission in somewhat jaw is not only an dana priest. he is also a professor of microbiology and an uncompromising advocate of 0 wastes agriculture . the condition agricultural is inefficient is expensive, is not affordable, killing the environments, and impoverish and great it is planned on the export in wealth and put in poverty. he sees the solution is secular food production, building an integrated agricultural system that recycled nutrients at every state. the 1st song i sent out was set up in benita capital, put a novel in 1985, several other african countries now have them to all the was closed into here.

there are some microbes, microorganisms, good ones that are recycling them, capture in the solar energy that water is now powerful and rich. so we'll use that . what amount to irrigate and take this one. now we can feed our animals, the fuel fight, water flows into song, eyes, many fish farms. we are catfish until happier feed on pellets produced on site from the byproduct of civil harvests. all this is worth water. recycle, run of water. not a drop goes to waste. after passing through the fish vans, the water is infused with nutrient rich manure and used to irrigate crops. we can grow as 3 times a year. 6 funds by her use in the west, from the big room, from the chicken, from any other thing here. they become immediately neutrons. if you look at the pope or the papa. c will water them without want to see how it is. the best of the

harvest is eaten on site, or it's sold to the community at nearby groceries towards eva in ro form or processing to nutritious. proto, the rest goes to feed the center, 4 legged friend. this is produce with a drop ins. fertilize by there wasn't a unit. and zip how the love it. even the via gas that's good to run machinery and equipment, is produced on the premises. we use the gas proclaim for lighting and generating electricity. so for you this year, if every community can generate its own energy, compound is development. the closed loop system seems like an ecological paradigm. but there's only so much that one patch of land can do for some guy to succeed in its mission of transforming african agriculture. they need to ensure that this green technologies proliferate cause of song guy is really trimming. we have this

young people who say for it in months, on average, every year we're sending about $400.00 young people. yeah. going to just really one of them is antoni. i let the be. he came from neighboring nigeria for a 6 month course on ecological animal and crop production. with us. i've been here are able to miss people from molly gumbo cynical. i'm an agent with this case. we get so unique. it's all at once we've done before. when you're done with a program between major see and that's what i've learned. but lot all of some guys, dri, nice, come from so far. feel l easy, you? so in have had this nearby problem oil plantation from his father. after graduating from some guy's training program, he's been busy making it more eco friendly. they don't put on his lap the. she'll take the oil palms, for example, for our parents are using

a lot of chemical fertilizers on grid, shameeka may, but thanks to our training, we now use manure as an organic fertilizer for oil palm. don't fall off of my some good. yes. you've got some guy on the map in the book to the lucille that's allowed us to produce better crops. you see when a greater capacity incapacity that's mon you is supplied by you source rabbits and more than 3000 chickens. and like some guy, you saw fun out there waste into a bio guest system of his own. while renewable bio gas is difficult to transport. so it's best used right where it's due, but it is not a perfect fuel. even phone guy acknowledges that binding the theme still contribute to the atmosphere is greenhouse effect. that's partly why the center is switching to solar. over $154.00 to voltaic panels have been installed so far, and not only on the rooftop. this i set up, i know is that

a weapon that the last from on the news we are producing very sensitive autism. so this is providing shade, so we call it greenhouse. despite all the new technology, godfrey, which is still a nation, never had this vocation of man to have nature. the connect had radical going into the design of them in full nature. for reality, if it does with nature and it's always smell of you. so we've come full circle. we started with agriculture in rhonda and ended up the fun in bennett . will they soon be using the tractors there to we'll keep you informed until next week. this is chris illema from ogo states nigeria, signing off. thank you for watching. as always, you can stay in touch with us and all our social media platforms. it is
