welcome to talking about hackers paralyzed between your societies, computers, leno, some are you and governments that go crazy for your data. we explain how these technologies work, how they can only go wilson for. and that's how they can also go terribly. what you know on youtube. oh, have you ever heard 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 m e's is sandra tino video coming to from compiler here in uganda and the one wall come from me, chris alone. the no good sleep nigeria sondra 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 st. him is conducting research on the green steel and how solar energy is being harvested on the surface of reservoirs. you're out in the fields and you hear a loud throbbing, ang, jane, 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 powered vehicle. but there are more environmentally friendly alternatives

as this project in run that shows. i mean, it's just a normal working day for members of the decor cooperative, nikki galli, the villages till the fields by hand. the many helpers 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. 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 we no longer wanted to euro. they tend to be noisy and dirty. diesel is also not always available and rise in fuel costs means that the often economically and viable from the outside. the solution looks remarkably similar. a to point to contractor with the 27 was car engine,

but the motor is electrically palate. a gentleman call make a developed this e tractor prototype along with the university of to galli. and the g. i said german development agency, that son converted thighs of 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. hello there, you've 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 to can release a battery and show it back and put the full battery on the truck route. so if we 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. my and the queen and his team from did this just for one day and working

on making the batteries more robust so that detractor can soon go to work on the dusty sunbaked fields. rhonda needs it, tucked up for other quarter mechanization to beat user friendly because of for reducing the depletion. fatherly it to maximize the productivity. agricultural product is t. rwanda has to increase its agricultural productivity to help feed it's rapidly growing population long periods of drought length to climate change or increase the pressure to make farming more effective and sustainable. the fact that the chapter is intended for use and more remote areas is a particular challenge for the developers in the team of v w engineer who the language the main point is to make an electric tractor as,

as simple and easy as possible. because it should be easy to operate. and the other thing is when it is simple and easy to maintain and to repair, to make the tractor suitable for working with landon fields, the prototype has to be further improved. when evac, the team of developers traveled through the country speaking to potential future uses, we're room room. we want import how the truck factor to be design and what will be the task of that the dog collector. and we also wanted to take into account some other activities that can be done by the tractor. and plowing isn't the only job the tractor should be able to tackle here. in rwanda, productivity and farming areas can only be increased if other farming jobs can be

automated. as well as the develop as a testing, whether it can be harnessed to help irrigate the crops. today we are testing the pomp 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 pull, then 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, 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 after 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 tosses easier. so don't forget to blame. we've just seen house solar 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 is solar pox that is right grease in $2021.00 energy production in the rope in union rose by 19 percent. but that's nowhere near enough to reach your slime. it goes, funding phase for solar pucks in this lea 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 his working. and if for you in the food 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 if a reason and use 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 solar parks is that they occupy spaces that could

not be used otherwise. and being on water energy production is more efficient. ben, 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 patients. 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, e. d. p. rock for their whole rock of surfaces that can be used and her skilled p, yes is just as they are in warbler. her, of course, respecting law, the environmental conditions that you have it scalable. it's complimentary to the other sources is not an alternative. it's a compliment area, so it's a solution to go further. and 3 chris piv of her changing and the colonizing

the array connects to the grid by the hydro power plant in the dam, exit solar energy can be stored or used to pump water back into the reservoir to generate hydro, electric power, the 12000 panels, and 25000 float us on the i'll give a reservoir, have been tested to withstand water, wind, and rough waves. the floaters are made in this factory in cash that year in spain's alcantur region. one carillo's atom land, if 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 with american amplifier. you're gonna feel north of him, we're, we're just a little company. but we grew ever recent years ago. now we're 20 people who work on the design, the commercial side and engineering. yeah. if anavia,

you're locked on the other brasil than it was. the reps, us plant liberal sand on the production site. we're talking about 30 to 40 workers that weren't that are hot and must everybody else understand bars in dublin, but it's a real success story for aaron. and if 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 al cave array covers less than one percent of europe's largest artificial lake. and it appears, planning a much bigger floating array on the lake as part of portugal to push for 100 percent renewable energy by 2030 this towers vince mark him portugal and the example to the world as well. with our 1st project in a hydro, them, and then placed the benchmark in all utilities in the world, especially in asia. as you, 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 exponential, especially with the setup of projects in so we can expect to see many more piece 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 carbon dioxide. 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 blast 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 now the iron and the me since we get feel 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. but in fall, we realize that we might have a chance now to out compete to 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 ion 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 then we get waterway brains that what website can be condensed recirculate reducing the process so that we really solve the root cause of carbon dioxide emission from steel making hybrid 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 that what we call the

demonstration plant, with a capacity of 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 branch. we initially contest it, it was it widely known that sweden has an abundance of hydro. electric power to met is one major factors that usual he but the amount of steel produce. there is also significantly less or maybe a 10th of what germany produces, for instance, is killing us like to see into on to in sweden also has huge or deposit so, or is no longer mine here in germany, you're kind of as nancy, so the conditions here are completely different us. 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 a temperatures of at least 1000 degrees celsius, a delicious bolt of 4 or 4. however, underneath what's 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 farm. and oh, 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. and the nathan of vanilla is kind of grass is common here. these are what trees and grass we still have, just get senselessly burned. when thinking about the problem, we thought, well, why not turn the grass that the people burn but into pellets pellets. 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're 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 bare hopes to bring both products to the market as soon as possible. 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 this, i believe they intend to sell the grass based pellets for 30 bye st. less than charcoal. 35 kilograms would cost 3 years instead of for the stove, they designed as planned for mass production here and under lam and go ok. 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 the tweet hash tag doing your base. we share your stories. less deforestation and more jobs solving to problems that was in keeping with the aims of a circular economy that we mentioned art this thoughts over shill? exactly sandra and add this old guy farming, benign. they've been using this product to since, but 198 is. but just how did they do it?

oh, good. everything's part of one big cycle and some guy agricultural center, which was founded nearly 40 years ago by father got feet and some with joe, a man with a mission in some of your 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 impoverishing where 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 stage. 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 been captured in the solar energy. got water is now powerful and rich. so we'll use that water amount to irrigate and take this one. now we can feed our animals, the fuel fight, water flows into so guys many fish farms. we are catfish anti lapierre, 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 farms, the water is infused with nutrient rich manure and used to irrigate crops. we can grow 3 times a year, 6 months by her use in the west from the big room from the chicken, from any other think. yeah, they become immediately neutrons. if you look at the proper, the proper see 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 near buy groceries towards eva in row form or processed into nutritious products. the rest goes to feed the center 4 legged friend. this is produce with a drop ins fertilize by there wasn't a urine. and zip how the long it even to buy a gas that's good to run machinery and equipment, is produced on the premises. we use the gas proclaim for lighting and generating electricity to tell 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 these clean technologies, proliferate cause of song guy,

is really training. we have this young people who say 4 months, on average, every year we're sending about 400 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 to meet people from molly gumbo cynical. i'm an agent with this case. we get so unique. it's all at once we've known before. when you're done with the program or the green box, major impact, what i've learned, but not all of some guys, dri nice come from so far. feel l easy you so in have had this near by paul or plantation from his father. after graduating from some guy's training program, he's been busy making it more eco friendly. you know, put on file is up up with the she'll take the oil palm, for example. if we bought our parents are using

a lot of chemical fertilizers there is on grid shameeka may. but thanks to our training, we now use manure as an organic fertilizer for oil palm don't fall off a muscle on the map in the book to the new see that's allowed us to produce better crop when a greater capacity incapacity. if that's mon you is supplied by you source rabbit and more than 3000 chickens. and like some guy, you saw fun out there waste into a bio gas system of his own. while renewable bio gas is difficult to transport. so it's best used right where it's reduced, but it is not a perfect fuel even from guy acknowledges that binding machine still contribute to the atmosphere the greenhouse effect. that's partly why the center is switching to solar. over 100 and 54th of all time panels have been installed sofa and not only on the rooftop. this solar panels is that

a weapon that so lash em from on. then if we are producing very sensitive their system. so this is providing shade, so we call it greenhouse despite all the new technology, godfrey exam, which is still a nation of this vocation of man, to have nature that connect that radical clinic to the design of them. in full nature for reality, if you dance 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 farm in bennett. will they soon be using the tractors there to we'll keep you informed until next week. this is chris illema from o go 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

a good buy for me, sandra. 3, nobody here in comply. uganda. do you remember to tune in next week? ah, with ha ah, with
