#135 You donated us a digger, it has arrived.

[Music] hey we got our biog gas system working so now we can boil hot water with gas produced from our food waste we're going to talk more about that in this video so you can see the entire process how we got here but first let me show you the newest addition to the team which we have right here welcome to new project Camp update yay look at him it's actually no I want to we got to be quicker it's here it's nice it's nice and warm I like it it's really warm it's already full of remote yeah she was she just said she wouldn't hear it she was real now okay okay okay first time testing the Digger um going to go to the bottom of the land [Music] radio there an hour message [Music] all right so it's finally here the Digger in Project comp took it little bit longer than expected few delays here and there but today we're going to give it a test um to use it a little bit note I'm an amateur I drove it once yesterday to base C and that's it I didn't really use all the sticks or the mechanisms to actually dig so you're going to see me trying that to see what it's like to be an amateur on a digger and um yeah hopefully it stays alive seems pretty good but first let me show you a bit about the machine so let's go straight to the main feature it has AI right there in this machine very Advanced and besides that the machine seems in pretty good condition and the main reason is that it's revived so uh repainted and taken care of which is nice because uh it means the Digger had some care to it after a few years but the downside is we don't really know how worn out it was but anyway we brought it here locally to a digger maintainer repair mechanic guy uh so it's all taken care of and good to go now so we can give it a try all right here we have a little coat hanger in order to record this I have a camera inside on the top and on the outside so you can see what's going on so time to get [Music] started so let's try to pretend to do a scoop [Music] okay so um no turning [Music] like that no no turning and then sort of scoop oh sorry I didn't want to scoop but I scooped well feel really imagine digging at the same time and driving with all these variables woo after the first try we were ready to start do some work but first I actually want to give this a try which is a big puddle especially when the rain is coming cars often either get a bit stuck here or they scrape as you can see it's pretty deep so I think I'm just going to go back and forth a few times see see if we can make it a bit less steep [Music] [Music] [Music] so road is fixed I don't know fix is the right word but it's a bit flatter and the holes are less deep it is one big mud pile so hopefully it dries up because now it still seems quite challenging to go to it with the car anyway I practice some digging next uh we're going to go to the place I had originally in mind to clean the road edges so here on the edges of the road there's quite a bit of soil because every now and then the road gets bad and they put a bulldozzer here and then on the edges all the soil goes but now a lot of water is Flowing but ideally this is more leveled with the grass field so the water can flow in there instead of on the road so there are all these piles here that kind of need to go so I figure let's dig it there or even with the bulldozer thing to flatten it a bit I don't really know I'm just going to give it a try and we'll see how it goes [Music] [Music] so here we are the job is done but I realized the time laap camera here wasn't working so it didn't really properly capture it everything is nice and flat now the water of the road can flow here it's easier to maintain but I guess first day on the job so not everything perfect chat next time I'll make sure to put on the camera and do the digging next digging job here we have this road and a lot of water is always flushing down in a Range which erods the road and it's also waste that the water could flow there into the P so uh want to dig up these edges so the water can flow over there let me show you a bit better the problem over here is the normal height of the road but this whole area here got washed out by the rain so it's slowly degrading the road which ideally we avoid and the water doesn't do that we're going to get the Digger and flatten this [Music] so I actually got started with the Digger right away because excited but there was one quite of an important thing which we didn't do yet and colen is doing it right now which is adding the name of the top donor in a very elegant [Music] way thanks Mark so we marked the Digger thanks for supporting and everyone else that helped out really cool to finally have the Digger here so chapter closed check uh it's actually still quite hard to move the thing and all these different joysticks and different angles you can move at once but really see a big difference between beginning to start with a digger and the end so I think I just need to make a lot of hours and get better at it but overall it's cool to having this big bucket and being able to do big Scoops because we can really do big Landscaping work by making more SS legs fixing roads a lot of work to do on this big piece of land and also if you want to know more about the Digger or technical specifications you can find them in the research module we also have one open question there which is about attachments because L we have this bucket which you can also attach other things like a drill to take out the roots or a brush cutter so you can chop the trees um or a grabber so you can pick up stuff let us know what you think is a good attachment for us so we can get the most out of this machine and in general I would say have a look at the research module because it's really where we share and document all the projects we do most of the work we've done actually there's also an Academy with more condensed up information and we want people to use it share it and contribute back with their knowledge so create one big knowledge database about sustainable living for free open source that's the project Camp Mission and one of the projects in there is also the biod digestor we started this last year and we continue working on it this year it's a bit of an iterative process um it's a bit of an experimental research project but it's fun to follow so let me show you some updates we made here we have the biodigester from last season which did not work uh we don't know why yet maybe because of leaks and this year we want to try a new version with the new setup up so first we will empty out all the old stuff and then fill it with new compost okay but maybe for the ones who just arrived a biodigestor is an airtight container where bacteria digests organic matter into fertilizer and biog gas this is a very simple way to understand it but if you want more details you can check update 100 or head to our research module so this B digester was built last season as a way to start learning this technology and building a prototype we had some friends visiting who had a DIY design which was easy to build it went good just needed a couple days to start producing gas but some leaks appeared and gas was not accumulating it was abandoned over the winter so now we need to make it work again it seems like I'm the lucky guy to take on this project but as a warning better don't eat during the next few minutes Bo I smell so bad yeah I guess this quite smelly so have something some trick some Tiger Balm always help nice cinnamon and yeah you can live to smell to have a bit he [Music] guys um now as we uh emptied all the liquid from this valve we now try to remove all the solid parts with are too big for this valve and yeah this will be very disgusting I need to do it to create more volume more usable volume [Music] there some gas inside this is the gas [Applause] bbes in there [Music] [Music] [Music] [Music] so now with the B digust are emptied we can start um making the changes uh one issue you can see here with the pipes they have the wrong lengths so to uh get rid of that we will uh build a new Design This is what I will do now the compost Inlet as I said before the designs of the pipes will be changed um the design what was built last year is what I called a top Outlet design uh you can see a diagram here and I will explain how it works a bod digester has an inlet for kitchen waste an outlet for Bio gas and an outlet for fertilizer in the top Outlet design all pipes are connected to the top surface of the bite adjuster as a result the water level rises to the Overflow point of the fertilizer Outlet the gas can exit the liquid biomass at the surface of the gas outlet pipe the problem however is that the inlet pipe is lower than the outlet pipe so we could never fill the besser to a level where the digested fertilizer will come out here so the easiest way would be to just use a longer Inlet but I think I know a better design which I call the side outlet and you can see a diagram here and I will explain how it works and what the advantage is in the new design called side Outlet the fertilizer Outlet is attached to the side surface this allows the water level to lower to the height of the opening creating a larger surface area for the gas to exit from the liquid biomass as I just explained um we will not use the top Outlet anymore so we have to close this hole so the gas does not uh exit here rubber gasket we are using Teflon to really make sure we have no leaks let's make the hole for the side Outlet design never mind now I'm burning the edges here to have a nice flat surface here you can see how I want to build the side Outlet this is the inside of the bite adjer on the right is the outside and the wall pass here in the middle needs to be airtight so now I will install the wall pass and then we can connect the uh elbow just enough arm for fight okay so now we can place the bucket for the fertilizer and install the Overflow this can just be put inside since it does not need to be airtight now I'm screwing the bladder into the outlet okay now with the new design built we will fill the B adjuster with water to do the pressure test and in case you are wondering the water is not wasted we can use it because we have to mix mix the cium with water anyway and additionally it's a even an advantage because the water will heat up or would heat up if we had Sun but maybe we'll have in a few days and yeah because we need to have about the best would be maybe 35° uh water temperature would be very good and if you're are saying now in the comments your gas storage is way too small we know that this is just for the beginning to test it because we want to avoid possible leaks with the gasometer which we have here but yeah this is for later when it works now the B adjust is filled until the necessary level so now we will close it and blow the balloon and then check if it if it has [Music] leaks pressure test the balloon is filled with air under pressure and now we will check if um the air is escaping somewhere as you can see when we put soap and water on the tube um we see the bubble is expanding so we know the air is leaking uh in the Overflow so we need to yeah find the leaks and try get bigger on them so finally after a lot of tries and a lot of waiting for parts the B digester is airtight we can see it here in the balloon which stays full for more than one day so let me explain properly we took out the first fertilizer Outlet because it was not airtight and made a new one basically what we used are glute connections with uh silicon as well instead of the screwed ones which we tried here before which didn't work because they tended to leak so now we can install the Overflow and it's ready to use [Music] to activate the bacteria we um fill the Manu into those barrels and add a little bit of water and during that I also tried to remove all the hay we don't need there are already living plenty animals in the manure here we uh keep the manure in the barrels and added water to activate the bacteria and now we cover it and now we need to wait a couple of days today is the day where we fill the manure into the B drer we try to remove the ha uh it's not important to remove all of it it uh just stay just very much slower this liquid stuff not the hay it's the good stuff gives a lot of gas we have to check the um temperature and pH meter uh pH value to see that everything is going all right everything oh we have 80 uh 38° already which is perfect we need 80 minimum and we have 6.4 uh pH and it should be a little bit higher but it will take some time and then it should be good at the moment we are waiting for the bite adjuster to produce flamable gas and yeah while waiting we will use the time to rebuild the gasometer to store bigger amounts of gas than the bladder only and yeah was taken apart to investigate for leaks and one potential error was found here where this metal piece was screwed in the plastic without a gasket or something so it's pretty likely to yeah to leak here and we will use one gasket on this side or I can always ask where this host connector will be with Teflon and on the inside um inside of the barrel there will be this gasket and then this not needs to be tight but not too tight now I'm going to fill the gasometer with a compressor and then we can see if it's airtight if it stays after confirming that everything is air TI we wait for the gas to fill the gasometer yeah it's a couple days waiting now I don't know how many I think nearly a week and I hope it's enough main now last time it was too much CO2 now the light isn't work oh did you see it yeah I'm pressing yeah [Applause] I'm so happy again again we can almost go a oh oh my God so wow super cool and the flame is so blue because of the methane blue wow thank you all for watching see you in next video let's go to Cafe ma no else want to join everybody and especially me are very happy that we have the flame now and that's why it's time now to feed the Bessa with our kitchen waste added to the C manure and for this we collect uh the compostable waste in this bin and we feed it once a week and also add the same amount of water and the kitchen waste we put here into the grinder and it goes directly into the bite adjuster I will now only add the rest of the water also I try to push everything down now so it goes from the pipe into the main chamber and now I will leave for holiday and hope everybody takes care of this and it don't dies or explodes while I'm away and then we see how it continues when I'm back so the bodess is producing a lot of gas and we want to use it and not use the propane gas we have and for that we have this stove which received from Tamira it was modified which you can see here because you need a mixture with more gas than air I use tape to close the air Inlet and remove the nozzle to let my bio gas out to tested how long uh like for how long we have the gas for we will make a little tea gasometer is empty now because the flame stopped and we didn't reach boiling the tea we have 71° and yeah so we need to make some improvements with the stove and also the gasometer but yeah for now we have the tea who wants biodigester tea C thank you everyone it's tea time thank you well it's it works first Improvement for the stove I will build a wind protection out of leftover wood we have okay the wind protection is done let's check it out yep it's wait after 12 minutes the water is boiling and we don't have much more gas but it's boiling nice the gaser can store gas to cook for 16 minutes which is not a lot for us so we will try to improve it and and the construction now looks very not good it's very loose so we'll try to build a new guidance and then we can add more weight here to increase the pressure and then we can store more gas to build the new frame for the gaser we will use the best material in the world basketball [Music] floor close this all I will use this piece of plastic I cut from a bucket from the [Applause] trash yep it's night [Music] okay now we need the [Music] water okay the water is full now and I will test the function with the comp [Music] ressor okay everything is connected now now we can open the valve and yeah watch the gas bring produced and start here in the [Music] gaser hello it's still me just with short hair and it's been a while it's going good we're using the gas which is very nice and but now today we also want to use the fertilizer so for that we will use the kitchen waste we collect put inside and then the same same volume should overflow and we can use it for the plants okay here we have the pure fertilizer and to use it I need some help this is Alana hi from landscaping and general help so what do you think where can we use it I think that the best place to use it would be on the fruit trees because it shouldn't be something that would eat directly know so I think that would be and I think they could do with some help here we have the fertilizer I think it's about 2 L and we need to dilute it with the ratio 1 to 10 so we will add 20 L and for this we can use um the pipe which goes to the pond up here instead of our drinking water uh-uh uh-uh it work [Music] everything with a bite dress is going good that's it
