the, the dream of revolution dictates as the most uh, was full of need that changed my life. the people hoped for a sara society. i imagined we would change the world. tens of thousands of messages from all over the world wanted to help reconstruct the country. this mission became the dream. it was simply a spirit of optimism where we encouraged each other, so many things were suddenly imaginable. their idealism mess it and

make it a dream of revolution. thoughts july 20th dw, the whole has a color that is green. one german research team is convinced that algy can help solve some of humanities greatest problems around the globe. biologists are hunting for micro organisms with extraordinary abilities, like lives the creating algae, which might one day generate climate neutral summit within the very 5 percent of globe black as far as c o 2 come some construction to go from the concrete production. yes. now here's a possible concrete substitute, that's the exact opposite. it doesn't produce c o 2 to absorb, it absorbs itself for over a year. we've the company researchers from kaiser slowdowns,

university of applied sciences to the depths of a spanish case where life on mars is being stimulated here on earth or in space. algae could be the key either can come up 1st, go for a 1st name and i'll give you all can take in waste materials and wasteful to then extract new transfer. mann's office with very just like and they can also produce oxygen. so as i can find the c o 2 weeks while creating oxygen in food, same time on this, okay? probably amongst the best organisms for producing food. but i don't know the an expedition in northern spain,

an hours drive from build out these researchers led by a biologist, me see a lack of toast. are exploring a cave in hopes of discovering new species of algae and furthering their research on known once. they're not exactly sure what awaits them. there are almost 300 caves in this valley alone. and some 4000 in all of count abriya. one caved in particular is of special interest to the german expedition team. the what they discover here is mind blowing. misha, yeah, lack of toast, finds organisms that bear witness to the very origin of life on earth, the god of him, how much do you much found this huge patch with one of the oldest sign in the back

scenery, aware, aware of the big cat's incredible things i've never seen anything like that. it's quite incredible. i'm at a loss to what we fidget closet, right. what's left him speechless is how these bacteria known colloquially as blue green algae can survive with so little light, the noise on one hand, we really want to discover and isolate new sign and bacteria and use them for the technological applications. at the same time thought when we have in such a marvelous habitat, the 1st question is naturally, how would they survive it? so that's what we're doing is we're measuring photo synthesis with this device. but we're also seeing to what extent they've adapted to the light and how they utilize the unofficial prices for the algae researchers, this category in caves is

a godsend. the only person might just the most in booking rock face. but for the biologist, it's a window into a fascinating world, an extraordinary multi generational colony. since you do some shopping, you can see these colorful surface here. these fluffy little gray green pads doesn't it's visa sign of activity. and so with these yellow ones here, these pink jelly light clouds striking the optic, that's the particular sy entered back tyria and we're off the glow. we go back to us clear, we'll talk each one of the oldest leaving. so i entered bacteria and back to so it's a very basic primitive cyan and bacterium that's leaving here along side more modern species. a bit of, of all the different li gimme they're all living here in the colon included. this is like the misha lack of toast and patrick young are thrilled with the wealth of research material they found and excited about the new questions that arise from it, the service in dust,

we know that they can survive without much lights 5, but we don't know exactly what the lower limit ease is also the question of how exactly this works in the low line situation. we've been counted deeper inside the cave, so i entered bacteria population. there is different than that. if we found different species, a certain process is a different to you and either. so the allergy here is quite class august responders and i can yes, they can photo synthesizing the dog. we've moved even further into the cave and despite the total darkness, find species of l. g. living here to feel comfortable, you know, a 100 down and there's only 800000 the line from above can reach them as a volume. allowances in the dog is a little they simply structure that physiology about that photo synthesis and the thing so they can use nothing in the visible light spectrum. but 1st industry,

we switch the exciting of this and they may also be able to draw from further along the range of light and the random non or in the fall. right. and for the still got was looking. couldn't you understand that it was spanish biologist, antonio gibson, who 1st drew his german colleagues attention to the case and sent them samples. it was the beginning of a great friendship between the spanish and german algae. researchers assigned him saturday and campbell a. you'll get tons of a new field of research. i find it very interesting in terms of the production and research of useful substances of materials. so it is not just the biological aspect which is already fascinating it and that's, but it's also the practical application. something you know. lovely. got them. but i think in that regard and do the patrick and michael's ideas are in line with us. a m. m, i can other words, we think we're happy to continue supporting them here, and we're looking forward to working even more closely with the most. but it's not

it. is that a push it till the here instead of you many that as the spanish biologist works for a company that wants to model mars missions here, they've set up a space station of sorts. deep within the cave. the algae research conducted by the german team could also be interesting permissions into space. escape and come up if it's time to take on those today that and if you had just a few minutes, a lines perfectly with our original plan to draw on the potentially lease unexplored micro organisms look at them all. apparently capable of producing substances that have not yet been recess. antibiotics, for instance, in a moment. so these organizations are in fish competition with each other. so they put to you santibanez has sort of these most in and out. i'm going with india and today using to scan it on and see if you think like produce new truth, other service food for other organisms. so like a service food for us, digital, simple video could all be possible. but english, i understand you meant that to be on video said a change of scene. we had to the

laboratory, a kaiser's low tones, university of applied sciences. the permits ends campus is home to the worlds the largest collection of terrestrial fiano bacteria, algae that live on the land, not in water. for study purposes, there being cultivated and liquid, none the less. over $350.00 species from all over the world can be found here. gums of march this year, or the i'm, for example here, your advice selected for cox and the upstairs from the i'm talk to the you to send you the how guys here we've isolated micro call us for it like our from very hope that's a region. so when i complete the new algo, we've identified even from sol involved in the arctic on the all can attend the, to the country. what does that do? the, the kind of you have to do it has a small red and a quite unusual that we don't know why it's the einstein as researchers started the

collection back in the 1950s, the algae from the spanish cave or the latest edition and could one day help us face the climate crisis doesn't face it that baby could somebody be covering and there were some of that kind of caught up in ice for example. cool. how they behave like rebuilding carl and producing a sort of troy piece kind of times he is one of our new projects here is to see whether we can use this as a submitted substitution as a cement, as a can be crossed. and um, yeah, 2 bucks, that's a menu of all the samples we collected are in here. do you think of something that tom, the german researchers are traveling the world on the hunt for new species of algae . they most recently spend 4 weeks in the add a comma desert, and she'll a while the whole spine of the cactus here, the other trend to polio samples. that's a special type of like in that grows on the tips of the tax id number is next period. assets are extreme locations. it's very hard and there's little volta venue

of the organisms can survive. the i can also withstand very high temperatures and by technological reactors, for example on somebody they will temper to an old phone. that's number one. number 2, in extreme habitats like that to organise you always find organisms that can do something very special from such as producing special active substances except for adopting specific you metabolic pathways. stuff like the big armstrong. some algy enter into symbiosis with fund guy in order to survive and extreme places forming. lincoln's patrick young, found such l. g, fungus, symbiosis, and the out of comma the fun. this becomes a kind of sunshade for the algae that is on the, on the, among other things. it also, it provides you the protection against the hush radiation one finds in the to come and visit the l. b a not mobile. they trapped in a stationary position and somehow have to protect themselves from the sun's rays,

which they can't avoid with a like and like this ones that task falls to the funds will ton, deputy produces it, and pigments in the case of the species. those pigments that green is yellow in appearance. another key feature, the colonies survives on very little water. these are all properties that could come in very handy, say in the development of new products. a beacon view, how much we turn organic waste into plastic funding. early march 2020 to the official launch of a research project called a waste to value the vision. at some point, l g will be grown directly on building facades and residents could benefit from the harvest. if bio plastics were able to thrive on such besides, it could also lead to growth and regional economies. all thanks to algae, green fuels could also be created using the same method. research

as being funded by the german federal state of rhineland, polite, nate, they see it as an investment in the future than just the one that in those kind of heard of that from the state level. many companies would benefit from becoming a little less dependent on energy supply as a credit, that's a significant consideration these days are no, we'd also be making a contribution to climate protection from here in rhineland. pleasant as reference, i was kind of kind of to hold the german federal ministry of education and research is also funding the project. they've granted 8000000 euros for the 1st 3 years. several partners are working with the team from parents sense his shots unknown to get caught out with currently enjoying an initial spark of interest move just hoping to progress as far as possible with the company's findings, ultimately incrementing some of the only thing is we've been, we're searching for yeah. so on this one, got it under forced out. yeah. minds of yes. wonderful was just right. does the 2

researchers are unpacking a new piece of equipment. a photo bio reactor that it will allow them to grow algae that normally live on land in liquid and thereby control the way they reproduce. this is the thing that's something that's needed for these items. the problem as well is that like growing a controlled by myself, i don't know log scale. this isn't that we can then control that grows here, and it kind of pre coach us and transfer them into launch or realtors, you up to one instance. soon analogy that's popular with biologists will be growing in this reactor as of some bars for you. so this, for example, is the elaborate, difficult to buy a technologist working without getting the syndic assistance. so it's used quite frequently and copes ideally, and conditions like past the due of 2 months. so that's what you see here. for example, here of the terrestrial out. can you provide those internal stuff in school or the multi cellular and thread like this as a med center is fill them in to you can see immediate time,

they tend to clump together when you have to prevent that with this mixing process . yeah, we're curious to see how we sound be close and then we have no experience with it yet. the, the, the, the convicts this. so i'm on to kind of follow that. you haven't tried yet. yeah. that was a comp. so was it will take a do in here. we don't even know yet. we carry stuff isn't much fun. you want us to inspire that. you know, the, the reactor is an important intermediate step towards producing larger quantities of bio plastics for climate friendly summit. one day exist, so this isn't close that window. she'd upset is a big difference between trying to force nature into the lab. that's to say, conducting experiments on a small laboratory scale thing and being able to think on a launch or industrial scale and couldn't. that's a whole lot of botox movies. and he's a student on us not 100 percent. that took the longest movies connection its modules the size of a window the researchers have already commissioned them. the idea is to grow algae

on facade inside these photo by a reactors. if it works, the process could save a lot of waste and c o 2. there are other benefits as well. some algy produced natural dies, some could end up on our plates, but it's something you guys lied to me and now we have solar systems on the roof in future. we could also cover the east and west facility with these al give reactors . i then even collect this would regularly come by to office the for the whole we to all of a star sales food order. so say the essence, cuz a lot of research is still required though space to the new research reactor will soon be housed in this former changing room. i understand. we'll be back for a visit once the researchers have filled it with algae. for now, it's back to spain. misha locker towson, his spanish colleague, have to send

a deep into the cave and reached the mar station. the aim here is to replicate living conditions on the red planet. as realistically as possible, the one day l g might be able to help space pioneers survive on mars. the minds can cut 2 out of 10 not to go up 5 stuff or upsets the side effects here you can say can waste materials and waste water and extract the nutrients from having a very different lights, like we have a light then compared to so i'll just put it in as i can, the volume, the c o 2 weeks heil to free creating oxygen and food at the same time by on. no, no, i'm going to put up some other i'll probably be among the best organisms for producing food in the space and can embed. i don't know what's important what the test station in the spanish cave, the company hopes to approximate life on mars. even if some martian conditions are

impossible to reproduce, we kinda nice to have abuse because obviously we need to take into account the only i know tech boss selling products. okay. the young thing would be actually to be a much about taking advantage that we are not the most well known brand new. we come made mistakes, diana and i can help us to have him play the bit of some records. and then we'd like to kind of best buy up there and you're going to let me buy all a g as an important area of research for this 1st bound, myers expedition and algae could play a key role here to the main line of investigation with office headquarters, engineering, of course, on the compiler to everything when it comes to the protocol for the a, searching for live and so long as the new teens and how come we want to be society and we need to research a piece and a ton of ours. you know, so everything that i've been to and should have on techniques and your team for

these young a food unity. so all that stuff is mostly place to put on the german researchers can hardly wait to find out more about the various ancient algae species. they've discovered in the case they're collecting samples back at their home laboratory impairments ends. they'll place them under the microscope for a closer look in then uh and then the one thing that will analyze the samples and then definitely take another look at that cheat. so we want to really see it's not just one species or 2 or 3 that will probably many, many different organisms living together have a little microcosm, so to speak. and one of the host to come when that's what we want to find out about the need shuttle to do that when we're carrying out genetic analysis to determine which organisms are living together here on this form, back to pam is hence, the new research reactor is full of life in the form of ality. now it's hoped they

will multiply. the researchers can grow various algae and the reactor unimportant step in cultivating alternatives to environmentally harmful plastic. because of 4 times on this, one of the crate advantage of this out to polano stock is that it can produce biomass names. that means if you give it sugar, so should think given additional carbon sources from fed starts to produce material gas a time. that's the basic building block for a really crime plastic that's called p h b for chauffeur's. buick plastic that's most by compatible and find degraded or combustible. is it used to sutures in medicine for example. see about it's prevented from somebody to, to, to need to buy them to, to our bodies would probably cope much better with organic plastic in our food than with conventional plastic. under the microscope, you can see the bio plastic that the allergy forms as white dots. so there's going

to be more, more time on this. but what's a problem at the moment going bike level w w s. study here is that we ingest around $100.00 micro particles of mica plastics with each meal. plastic. that's the equivalent to the 2000 pulse, because a we can go back for 5 grams each week. um, that's the equivalents of a credit card division in minor to take that means the don't have rich that everyone in the well, every week is each of a credit card with a plastic and it should be cods a cluster. eventually the laboratories, research reactors will be replaced with these window modules. then everyone can watch algae at work in their own window. the americans 1st, this is cooling called, so to speak. and you know, but some of these things are much less voltage just in their sales price. 90 percent less real time. they have better gas exchange, the easier to harvest. and so that is what this is on newest model for growing side effects here in the future in sort of 2 out of the 10 on so just dies could be

grown here and these beside windows or cosmetics or even food. this and she has the cussing somebody out even in china? no. yes. as a traditional new yes dish for instance verse, that's the most talk flag in the form of i'll give it's collected from the test but we can grow it here under these conditions. and then set it where it's like com, be crowded in the open liquid process on each box and then it will take some time before the 1st products made impairments ends come onto the market. we still have a few years to wait to for the 1st organic concrete produced with spanish cave algae use of trucks. this block is now 1st pro so tied on about 2 to you. we introduced to cyan and bacteria strain into the concrete in process of it's not yet one from the cave though. this is a bar tree strain is about how we carry down south those preliminary tests. with it . the test to see whether this process works with cyan or bacteria, or

a total of on, in the loan to and we want to work with the cyan and bacteria from the case since they calcified naturally. we can then use the process for concrete productions in this way. the system can be another 2 to 4 years before we've optimized decision on the door. just too soon to tell. yes, if we're on the right track, the in our fat in the eiffel region, a metal construction company is building for large bio reactors. the window modules will be 2 meters 40 high one meter 42 across. now the question is, which one goes to the bulk and then which at the top of this one here and that there is one the algae research here. michelle, alaska chose the seeing the modules for the 1st time today because audio, bennett is tight. amazing. we need to really think, okay, that should have been roughly key, but then you see how big it is in reality and the dimensions that i mentioned that

we've never had before. and that's also really important, does look, we're always working on the bar to scale. use 100 milliliters by maybe 10 meters is the largest size, but see in our, of 100 leads to prove us a whole lot of a story that we're really getting into it now on the ground. this guy, i don't think me personally going, it's going in close in state of the state of rhineland, pull out native, picking up the bill around 80000 euros to produce 4 modules. the reactors can be set up in a laboratory. however, the researchers can also hang them on building facades and grow algae. there is nothing i can put them right. that's as far as the even the water comes in from the top. so i'm just just mess with the status and then spreads through the holdings here. we, on the, when it trips down, it's fed out talking at the bottom and circulates back to the top of the down whole slide to see if we get them for the small metal and steel construction company. it

was quite an order, not least because they had to procure acid resistance, stainless steel. but when i read the cool for tend isn't so bio reactive at 1st i wanted what it won't. so is it something atomic. that's what it sounds like. it 1st go in retrospect, so it makes a lot of similes thing's old. i must say, i find what they doing. they have very interesting discuss it. i'm a fan of the projects within for you. i'm gonna find it to prevent the algae in the module from getting too much light or dying from overheating. sun protection is built in the fact that it never disruption so high inside of the react and must get too hard. good. because otherwise the out you would get to halt as well. and di, um yeah, that's why we've changed it from the sun 1st from above. and then again from the side to then we'll have called, the recounts and the codes that will surprise or provide even more shane for the result. is this under course of a truck and especially for them to act on the lp and the reactors will soon be producing file, plastic and absorbing c o. 2 from the air. they'll be hung on an actual facade in

stuttgart. for research purposes. michelle lack of toes is convinced l. g reactors like this, have a great future ahead of them and will one day be part of every city escape. this is this moment tom view like photo more tight and then the way we have photos of all tags were in the 1970s. we've developed it. so just being a new crop quickly, we can actually get into use of all the houses in the house is ultimately that's up to the politicians originally intended us to put it. if they subsidize, it doesn't feel good will happen very quickly without decide the world of cost. well, it's certainly part of the mix forced time from feeling for now the l. g. researchers from parents and still have a lot of exploring to do in every corner of the planet the,

the leasing moles, such as in the human names, almost have to find irritate. using discount remains of melts, of places to construct, suspicion most are reservoir while also testing innovative water saving cultivation message india in 15 minutes on the w to actually cause manuals inject you belong to the 77 percent to come to i don't good and 65 full was last those top 5 years,

3 reasons why 1115. we are here to help you make up your mind. we are here on please find your mind. so all the topics i'm much it to you from trouble fixed a new culture. and in 15 minutes, let's say together, parts of our community life on the research is now on the think the forward is twice think ahead or with outside the box on your but always remember to think for yourself. we all had to find it was incredibly like this sort of driving you with free information.

these are made for mine. the almost half the stores stand empty. daycare centers don't have enough children. and businesses con, find enough skilled walk as a small town in the german state of saxony made find to his last over 5000 inhabitants since german reunification. those who have laptop above all young and well educated guess beyond the default commerce, seeing it everywhere in our city, persecute construction sites are at a standstill because of a lack of material. and.
