man, because if we lose too much of it all wrong, we mess things up, risking brain damage. so let's stop this self sabotage. humans and multitasking watch. now on youtube, v. w documentary, the whole has a color, it 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 limes to creating energy, which might one day generate climate neutral summit. for 10 to verify percent of blood block as far as c o 2 comes from construction to the from the concrete production. now here's a possible concrete substitute. that's the exact opposite. it doesn't produce c o 2

to absorb it absorbs 12 for over a year. we've accompanied researchers from kaiser's loud tones, 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 get those can take in waste materials and wasteful to then extract nutrients from mann's office. we've already to live and they can also produce oxygen. so as i can find the c o 2 weeks heil create to oxygen and food. same time on this. okay, probably amongst the best organisms for producing food, but i don't know the

in england an expedition in northern spain, an hours drive from build out these researchers led by a biologist me see i lack of toasts 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. mission yeah, lack of toast, finds organisms that bear witness to the very origins of life on earth,

the god of embodied steve, i've just found a huge patch with one of the oldest son and effects henry, aware aware of the big catch, 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, weight 200 on one. we really want to discover the isolating. you sign a bacteria and use them for quite a technological applications at the same time thought when we have in such a marvelous habitat. the 1st question is naturally, how would they survive? so that's what we're doing is we're measuring photosynthesis with this device. the we're also seeing to what extent they've adapted to the light and how they utilize the unofficial bye.

the for the algae researchers, this can debris and cave is a godsend. the only person might just see a mazda you're looking rock face. but for the biologist, it's a window into a fascinating world. an extraordinary multi generational colony. fidget isn't having. you can see these colorful surface here. these fluffy little gray green pads, doesn't get these as i enter back here you go. so what these yellow ones here? these pink jelly light clogged, so striking the optic, that's the particular sy entered bacteria and we're off the flow. we go back to clear, we'll talk each one of the oldest leaving. so i entered bacteria. and so it's a very basic primitive site and a bacterium that's leaving here along side mo martin species, a bit of a voltage differently getting their own living here in the college and career. this is like the misha lack of toasts and patrick

young are thrilled with the wealth of research material they found and excited about the new questions that arise from it to the dust. we know that they can survive without much light spots, but we don't know exactly what the lower limit fees for the body is. also the question of how exactly this works. in the low line situation, we've been counted deeper inside the cave. it's got a cyan or bacteria population. there is different than that. if we found different species, a certain process is a different to you and or 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 enough in the town and there's only a 100000 for light from above. can reach something as a volume. the largest in the dog is

a little they simply structure that physiology about that photo synthesis. and so they can use most certainly 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 so got was looking, couldn't understand. 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 to the he didn't have it even gumble a. you'll get tons of a new field for such. i find it very interesting in terms of the production and research of useful substances and materials. so it is not just the biological aspect which is already fascinating it and that's, but it's also the practical application of something. so you know, that really got to them. but i think in that regard, these are patrick and michael's ideas are in line with us. a and i can other words,

let me think we're happy to continue supporting them here and we're looking forward to working even more closely with the program most. but it's not it. is that a push a 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 escaping coupling system and take one knows that idea and if you had, there's a few minutes aligns perfectly with the original plan to draw on the potentially lease unexplored micro organisms or gap them all apparently capable of producing substances that have not yet been recess. antibiotics, for instance, at the moment. so these organizations are in fish competition with each other. so they put to you santibanez things sort of, i need most of it didn't know, not incompetent yet. and today you was interested in it on a tv, i think like produce new tooth as a service, food for other organisms. so they could serve as food for us. digital. triple a

video could all be possible. but english what, but understand, he meant that the, on both of us, it 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 world. 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 vice selected cox at the oaks is from the i'm talking to the eunice cellular. how guys we've isolated mike or call us for it. like how go from very whole this of regions and a completely new algo we've identified, even from sol involved and the optical stuff i'll kill, attend to this country. what does that do? the, the kind of get to what has a smaller 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 by the kinds of iceberg companies, there were some of that kind of caught up in ice. for example. cool. how they behave like rebuilding carl. i'm kind of producing a sort of truck. he's 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 man of all the samples we collect tutoring here. do you think of some of the german researchers are traveling the world on the hunt for new species of algae? the most recently spent 4 weeks in the out of comma desert and she'll a while a whole spine. it's a cactus here, the other trend to police samples. that's a special type of like,

and it grows on the tips of the text i. then it 1st is an explicit ser xtreme locations. it's very hard and this little volta venue of the organisms can survive that i can also withstand very high temperatures and by technological react as for example, on somebody 0 what template to an old phone. that's number one, number 2, and extreme habitats like that to organs. you always find organisms that can do something very special stuff, 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, the found such algae, fungus, symbiosis, and the out of comma. the fun, this becomes a kind of sun shade for the algae does, is on the, on the, among other things. it also provides you the protection against the hush radiation one finds in the to come and visit the l g e and not mobile. they trumped in

a stationary position and somehow have to protect themselves from the sun's rays, which they can't avoid with the like and like this ones that task falls to the funds will con steps. they produce a certain pigments in the case of these think she's those pigments that green is yellow in appearance or 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 probably between 10 organic waste into plastic abundance. on early march 2022, the official launch of a research project called the 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,

greene 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 and on the gift stuff on that. and those kind of hit us on, on the state level, many companies would benefit from becoming a little less dependent on energy supply as a product. 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 outside of kind of to help 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 up with currently enjoying an initial spark of interest move just hoping to progress as far as possible with the companies i need, ultimately implementing some of the only thing is we've been researching for years, so on this one. got it on the 1st top. yeah. mine's of yes. wonderful. just great.

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. a lazy thing, 100 something that's needed for these items. the problem as well is that like rolling a controlled amount of stuff, i don't know large scale. this isn't that we can then control that grows here. and it kind of pre coach us and transfer them into the loan to react with exact one instance. soon analogy that's popular with biologists will be growing in this reactor as of some buyers for you. so this, for example, is the elaborate, difficult to buy a technologist working without getting with the system because the stairs, it's used quite frequently and copes ideally, and conditions like past the due of 2 months. so what do you see here, for example, of the terrestrial out? can you write those internal stuff in school?

the multicellular and thread, like the little met syndic these fill them in to you can see immediately they tend to clump together when you have to prevent that one with this mixing process. yeah, we're curious to see how we sound be close and then then we have no experience with it yet. the, the, the other that's been fixed. so i'm on what kind of follow that you haven't tried in lieu of a comp time as well to do in here. we don't even know yet we carry out as much fund you want us to expire, then we can move. the reactor is an important intermediate step towards producing larger quantities of bio plastics or climate friendly summit. one day exist. so this isn't close that window seed upstairs is a big difference between trying to fools 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 the least 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 and something. lots of. now we have solar systems on the roof and future. we could also cover the east and west results with these al give reactors. i then even collect this would regularly come by the office, the for the whole we to all of a star cells, food order cabins, as 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, kept 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 algae might be able to help space pioneers survive on mars. minds can cut about 10 to 5 stuff or upsets or to sign 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 um they then compare to you. so i'll just put it in as i can, the volume, the c o 2 weeks hail to fit, creating oxygen and food at the same time by or no, no mixing products and other. i'll probably be among the best organisms for producing food in the space. and can embed. now let's see 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 cannot say of abuse because i'd be willing to take a look on the, on the, on the boss selling products. okay. the young thing would be actually to be a much about taking advantage that we're not the last. why don't we come made mistakes? diana and i can stay on the bus to have him play the bid of something. but of course, i didn't read that can help us to somebody up there and you're going to let me buy all a g as an important area of research for this 1st bound. mars 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. i've been new teams and how come we want to be

society and we need to research a pc and a ton of ours. you know. so everything that i've been to and should have on techniques and your team, per lucy on a food unity cell. all that stuff is more thing 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 demo, 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 are probably many, many different organisms living together here, a little microcosm, so to speak, and one of the host to come when that's what we want to find out. i'm on the need not to do that. we're carrying out genetic analysis to determine which organisms are living together here on this fall back to pair ms. hence,

the new research reactor is full of life in the form of ality. now it's hoped they will multiply and the researchers can grow various algae and the reactor unimportant steps and cultivating alternatives to environmentally harmful plastic. because of 4 times a year on this, one of the crate advantage of the southeast diploma stock is that it can produce by advertising things. that means if you give it sugar. so given the additional carbon sources and fixed costs to produce material gas it, and that's the basic building block for a really crime by plastic. that's called p h b for chauffeur's fuel plastic. it's most by compatible. i'm fine to grind or combustible. it 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. there's going to be more more time on this, but what's a problem at the moment going by global w. w. s. study here is that we ingest around $100.00 micro particles of mancha plastics with each meal, plastic. that's the equivalent of 2000 pas a week or 5 grams each week. um, that's the equivalent to the credit card division in minor to take that means the toner of rich that everyone in the world every week is each and a credit card with a plastic and it could be cards 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 to you about some of these even much less voltage. just an aerosol sprite, 90 percent less full time. they have better gas exchange, the easier to harvest. and so that's what this is on us model for growing side

effects here in the future. in sort of 2 out of 10 not just dies, could be grown here in these beside windows or cosmetics or even food. a vixen, she has a 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 that we can brought it here under these conditions and then set it where it's like comp in crime, in the of a 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 prototype. i'm about to, to you, we introduce to cyan and bacteria strain into the concrete in process of it's not yet one from the cave though. this is

a bar treat strain energy about how we carry down south those preliminary tests with a test to see whether this process works with cyan or bacteria, right? so i'm in the loan to and we want to work with the cyan or bacteria from the cave 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. either too soon to tell us we're on the right track . in our hot, 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 bottom in which at the top of this one here. and that there is one of the research here and michelle, alaska chose the seeing the modules for the 1st time today because audio bemrose

type, amazing key to 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. those are for who is working on the bar to scale news. 100 milliliters by maybe n z is the largest size, but see in our, of 100 leads it soon, but that's a whole other story that we're really getting into it now on the ground. this guy, i don't think, let me push the going. it's going in close and steve, the, the state of rhineland collab, nate is picking up the bill around $80000.00 bureaus to produce 4 modules. 3 actors can be set up in a laboratory. however, the researchers can also hang them on building facades and grow l g. there is nothing can put them right on. the water comes in from the top just just makes sense and then spreads through the holding. terry, on the when it drips down it's fed out talking to the bottom, then circulates back to the top,

down whole slide to simply get them to be the normal for the small metal and steel construction company. it was quite an order, not least because they had to procure acid resistance, stainless steel, for the ocean. when i read the cool for 10 does into bio reactive. at 1st i wanted what it was. so is it something atomic? that's what it sounds like. it 1st go in retrospect so it makes a lot of sense from going. i must say, i find what they doing. they have very interesting. 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 hindsight of the react to must get too hard good. because otherwise the l 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 the event will hang cold by the recounts. and the cords that will sprang toward provide even more shade for the result. is this, under course,

the 1st type of assessing treatment will be axel, the l g, 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 elegy 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 web thoughts of all tags were in the 1970s. we've developed it so it just being a new crop quickly. we can actually get in to use those on the houses in houses. 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 the size of the world of cost . well, certainly part of the mix forced time from feeling good 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 ego africa, carbon offsetting projects are sprouting up all over 10 young ladies here to that is the people attending a predictor and i'm going to the single unless i did find a photo route to see exactly what can these efforts really make a difference in 30 minutes on the w fast, faster,
