“Of course it’s always the middle of winter when I decide to work on something like this”
- Cut to 2020 where Cody is throwing in sugar in a futile attempt to jumpstart a compost in the dead of winter. Never change Cody
Then building a solar algae farm the day after the winter solstice
Oh man, I get the sudden motivation to do things at the worst times too. Visiting family where I'm several hours away from my PC? Suddenly I want to work on my book. Middle of the night? Suddenly I want to start exercising. And then when it is a good time suddenly I don't have the motivation anymore, so I have to force myself to do it.
1:45 "i was gonna do this but that is too simple", 4:02 "well that didnt work so ill replace it with something simpler"
Is that not how it usually goes?
Frankly this is the best part of Cody's videos, IMO. He shows failures along with successes.
yolo swag that's Science for ya :)
anonymous:
Where on earth did _this_ suddenly appear from?
+interesting 482 But Bush (administration) did do 9/11. ^_^
9:45 "please don't tell me cody is gonna pour that without even a makeshift funnel"
...
oh my god
wtf eww
Lol but tf that shit Gross
Lol see what I did there
10:25
Thank You Google! That hurt me
I like those clear gloves your wearing. It almost looks like you don't have any on!
meh to Cody there's no poo, it's just a bunch of molecules sticking together he can deal with that bare hands
@@m0nty90 yeah, he lost his sense of smell YEARS ago!
It adds flavor when eating.
He using glove when touching mercury but wearing glove when touching charcoal. Classic Cody
Never borrow tools from Cody, never! :)
LMAO!!!
13:14
“If you guys are watching in the year 1218”
Un refutable truth that Cody successfully built a time machine.
Actually .... 12018 😉
12018 HE (human era) is also known as 2018 AD/CE
hey Cody, my parents work with koi and we use sodium thiosulfate to get rid of the chlorine in tap water. we've found that the active ingredient in dechlorinator evaporates after about a week once the container is opened. we use crystallized sodium thiosulfate and if you would like i can send you some
Interesting I hadn't thought of using thiosulfate; besides increasing the H2S production I cant think of any reason not to use it and whats more I actually have a bunch on hand.
well im glad that i helped :D
Michael Jones Sodium metabisulfite does the same thing.
Michael J
Except that it is used to sanitize everything when making your own beer and such.
You have some really cool projects.
Awesome to see you tackling this Cody, I'm excited to see it progress. Human "waste" will produce methane. I've had successful tests with it after feeding it sugar.
Grant Thompson - "The King of Random" hi grant
Grant Thompson - "The King of Random" alrite? how's ur day goin
Grant Thompson - "The King of Random" sup
Grant Thompson - "The King of Random" I can confirm there is methane. My farts are VERY flammable
Me too, ive done countless test lighting my farts on fire
Cody! please make liquid ozone and add it to your collection!
3ArtDigital I agree
3ArtDigital Yeah! Also he could patch up the ozone layer with that! (Being sarcastic)
And Jeramy you should've left out the brackets and caused a comment war
I thought ozone wasn't stable enough to be a collection thing.
drink it..
8:00 I'm eating chocolate chips, but go on
You won't believe, me too. But this is science, I think it's totally fine.
Jorge Daniel And I'm eating Cocoa Puffs
And I'm eating rabbit droppings at that point, but continue please....
I’m eating chips

Wadup? Love all the vids. We have a biogas plant in Germany that works by the same principle, digesting the pig poo from ours and neighbouring farms. By the time it has fully fermented over about 150 days there is basically nothing left but water and minerals that then get spread back on the fields as fertiliser. All the energy in the poo that would otherwise have evaporated into the atmosphere is converted into methane and used to drive stationary truck engines that are coupled to generators that feed into the national grid. The heat produced by the engines heats the pig barn and the neighbourhood. In a year this saves the equivalent of about 1.7 million litres of heating oil. The technology is still too expensive to make bg plants self sustaining but vids like this will get more people thinking about how to make the whole process simpler and more efficient. Good on ya.
You could stick some stirling engines on those heat producing engines to get even more power back!
Greg's Wildlife good thinking :)
In the UK, biogas is big business for farms. Mostly fed with manure, silage, and food waste.
My employers do analysis of the feedstock going in, and the digestate that comes out at the end of the process, along with other agricultural testing.
3:00 Introducing: The Auto-Fap 3000
Alex Smith hahahahahahha
thats the most original use of magnets in youtube atm..
I laughed, Thanks :D
Alex Smith lol
Some people are into Sounding...
Once you have usable methane you should experiment with Bioluminescent Bacteria. I've always wondered about the feasibility of an ambient lighting system for walkaways and such.
That would be very cool. I could also see this being used as a company, with the company having return customers since the bacteria is alive and would need servicing.
Ooooh yeah!
MadJustin7 I have meaning to do these tests myself so it would help me greatly to have someone like Cody who knows more about science to research the topic
"Of course it's always the middle of winter when I decide to work on something like this".
Ughh, same. Wiring new outdoor lighting fixtures and such when it's been snowing all week isn't fun.
9:56 Ohhhhhhhh Cody you spilled it a bit.
im watching this in 12,017
Toh Yong Sheng well said
Don't you have direct mental interfaces or holograms yet?
It's a typo, he means 12/01/17. But that was yesterday and this video was uploaded today... _illuminati confirmed_
Toh Yong Sheng You people don't get this...
Go watch Cody's New Year video.
Next a methane rocket engine please!
+ 1 We need a methane rocket Cody.
Sam Sokolov Nerdfighter i see.
We do need a rocket! I'm actually working on the liquid oxygen today. though at this point I doubt anything will actually fly this winter. might get some tests in though. :D
I can't believe this was four years ago loved this series
after finding your channel only about a week and a half ago, and watching the majority of your videos, seeing that a new video comes out gives me chills, YAY! also gotta love that utah weather, I witnessed the majority of the recent snow fall melt in a single day here in the south end of the valley
Was eating hotwings when Cody started scooping poop.
Those were some fine hotwings.
This is a brilliant project, I'm looking forward to part II. I'd really appreciate it if you could give us a conversation of the temperatures into Celsius (SI units), I'm lost when you talk Fahrenheit.
Cool video, loaded it up before I went to bed then started binge watching most of your popular uploads, nice work
Oh my! I love the partridges.. they are beautiful!
I dont think I'd be able to handle poop to comfortably like that! xD
it made me sort of uncomfortable drinking coffee while watching this
Mohammad Saad probably because you call it 'poop'
Mohammad Saad all you gotta do is put on a pair of gloves.
At least you weren't eating Cocoa-Puffs, lol.
oh it was not coffee ;)
I first red the tittle as "Cody's Methlab Generator" and I thought, "I knew he was the real Walter White".
you might want to learn how to type first before attempting to construct a methlab
You do great work. We need many more smart folks like yourself around.
When a guy talks about what kind of droppings is better, that guy really knows his stuff!
I can't wait for the year 12,018 to see how this turns out.
Byron Ramey I noticed that,and started rolling in the comment section to see if anyone else noticed xD
12018 HE (human era) is also known as 2018 AD/CE
Any plans with that Methane?
Broockle human free fart power
He plans to take out the 'ane' ( ͡° ͜ʖ ͡°)
I mean you won't get much power from just that tank. It's usually used for things like cooking or heating I think. And they're usually much much bigger if they're used for such things.
But this tiny one I wonder what kind of projects or experiments he may want to do in the future.
here is the plan: get this design working, perfectly do some science demonstrations with the gas, and then make one that is 10 times bigger.
Cody'sLab cool
This was posted on my birthday! Thank you!
I get excited every time Cody makes a video 😊😊😊
I'm watching in the year 12,018!
howed episode 2 go over?
he got you beat
It was a horrible waste of time!
+Cody'sLab it wasn't pleasant :)
you mean 12,017?
My mother in law is far more efficient at producing methane.
The flesh dripping of the body of my burning cat produces more than that.
MEOW! MEOW! MEOWWWWwwww...................
Does she fart
I was waiting for this comment
Awesome Cow In what universe is this comment socially acceptable?
Colathebuilder - the best one
All cats deserve this fate but much much slower ( as long there are no dogs)
revisiting old projects is a great idea
great video, looking forwards to seeing the rest of this.
internet issues luterally made me watch 2 times the length
I know the feels. I kinda wish UA-cam would bring back the unlimited buffering feature; I used to be able to pick out 30 videos, get em loading, go to bed and have things to watch the next day.
Cody'sLab lol i could wait for vids to buffer while i play games
also i realised i spelled literally wrong :3
ALTHDS me to
i had to install a script on chrome to allow this
Hey Cody, I'm no chemist but I do brew beer and I have a question. Would co2 effect the process? It is heavier than air and would displace the oxygen out of your container. Helping along the process or do you need the bacteria to work in 2 stages one where it uses the oxygen and then stage 2 the anaerobic cycle where it needs the lack of oxygen? Talk to some guys that brew beer if you need anything for us it's all about the bacteria. Cheers keep making great videos.
The heating system is very cool. it reminds me of the way a radiator works when you heat a home. I'm thinking about using something similar to that with my biodigester. I made mine out of 5 buckets from menards, all connected by PVC piping.
Dude, another long video thank you cody!!
@Cody'sLab / #Cody'sLab / +Cody'sLab
Methane generators are a big business in Sweden. They use it to produce Bio Fuel and heating up their barns for the animals and such. Noticed you had mentioned making a 10x bigger version. Perhaps you could use this principal of heating up as a source to heat a Greenhouse up over winter, see how that goes or similar.
That would be fantastic idea. Use the greenhouse to grow rabbit food. So it's self contained.
do the rabbits have a space where the floor isn't a wire netting? It must be painful for them if they don't have a plain surface to walk and sleep on
Another major point of concern for those rabbits is they need plenty of time *outside* of that cage in order to be healthy.
they're rodents sure, but rabbits are extremely active and have those powerful legs for a reason. You won't end up with a happy bunny if they don't get several hours out of the cage a day.
Like any other rabbit owner he probably know what his pet's need you dont need to be concerned if he were an animal abuser he sure as hell wouldnt put em on a video on the internet.
The issue with making assumptions like that is there are far more people who have rabbits that *don't* know how to take care of them than there are who *do*.
I'm not saying Cody doesn't know what he's doing, I fully trust he does, but I'd really like some form of confirmation since far too many times I've seen rabbits not get taken care of properly.
look out Cody, the rabbit police are coming.
TerrahBite I dont know whether you've watched the video but outside it's nearing a foot of snow. That's not rabbit weather. Im sure they do get time outside but I should imagine less so in the current conditions. And as for the mesh floor, rabbit natuarally live in cold rough burrows and cross rough terrain regularly. A fine mesh floor with gaps smaller than their feet will not hurt them whatsoever. I feel you think that since they're small and fluffy they aren't hardy and that's simply not the case.
Thank you for the video Cody. I really enjoy them all. I even admire your brain
Cody, how do you have that kind of knowledge and when in your life did you start studiyng that kind of stuff? You're like a genius! Love your videos.
Sorry i just have to point this out, If those rabbits are on wire cage floor, That can be painful and cause a condition called bumblefoot, where thier feet swell up and get infected from pressure sores from standing on wire all day
Fizzbuzz you stoopid
Literally said they had wood pellet bedding
Jason Kimes no, if you see the cages properly, they don’t have any base
Fucking idiot
I'm sure that smells *AMAZING*.
so close to one million subs keep up the great work cody
Great video dude, looking forward to part 2 🙌🏻😎🙌🏻
7:14 “Oh no! Mommy, I spilled soap in my poop bucket 😭”
Do the floors of the cages not hurt the animals' feet? :o
Mattia Schmid They do. I was pretty sad.
no, the wire is close enough together so that it won't bother their feet. Plus, animal feet is tougher than ours since we wear shoes all the time.
budmeister It doesn't matter how small the gaps are cause they hurt no matter what.
well yeah but can't they still get inflammations if a toe or something gets stuck? just curious ^^
There is a perch in the cage, don't you think if the floor was hurting their feet the birds would choose to be on the perch?
holy Cody you're so close to 1 million keep it up man you deserve it!
Cool man, can't wait to see how it goes.
Thanks good internet not provide smell.
it doesn't smell that much and for "that much" i mean almost nothing, and usually the smell, if you only have rodents, comes from urine
Joachim Von Grimorium Rodents are lagomorphs, but pretty much the same thing.
Rabbit poop doesn't smell bad, the trash bag itself is what smells so bad, I don't know why, but it's the trash bag that smells bad.
Because Cody lives around it he doesn't notice any smell at all. But anyone who comes over would, even if they're too polite to say so.
Cody is the true DIY God
I like those french partridges! Beautiful feathers for flytying!
Cody man, your so awesome you make my cheeks quiver at the thought of your knowledge.
Don't forget to keep the aquarium heater submerged in water almost to the top. If the glass is not fully submerged the heater will crack open. There is usually an indicator line on the side.
im jealous of the half-foot of snow cody gets; in the east midlands all we get is a bit of slush if were lucky
BocbinPlaysGames annoying isn't it mate. Had some snow today was melted in 5 hours
BocbinPlaysGames Snow is only nice when it's white and you see it. When it starts to melt, it's the worst... Got 25cm of snow the last 3 days and now its melting, with -10°C and below at nights, it all turns to ice. Too dangerous to drive, too dangerous to walk. A pain in the ass.
BocbinPlaysGames in arizona we get lucky if it rains
dude fuck snow, shit is fucked up
Those birds are beautiful!
Cody, you are by far my favorite youtuber.
awww the birds are so cute and fluffy! I love them so much 😍
also Cody built a poop engine, that's pretty cool too.
Cody you should make a video on prison wine and how it works
Be carefull with using aquarium heater without placing it in water as you mentioned in the beginning. It will break. Nice video and I´m looking foward to see cool experiments with methane :)
Love your videos Cody!
I like how you said if you are watching this in 12018. Wonder how many people think you just misspoke :)
I truly hope you meant 2017 not 2018, I can't wait a year to find out 😂
Could you burn the methane that will produce to create energy to power its self, and access to store?
this one probably not but a larger one sure would: cube law, twice as big, twice the heat loss but 8times the methane production.
Shouldn't be the heat loss 4x bigger?
TheAllegiantTraitor no because as volume goes up the rate of heat loss goes down.
If you multiply a side of a cube by two, then it's surface should grow 4 times, so heat loss must also be 4 x higher. but volume increases 8 x so it makes up for it by making 8x as much heat
TheAllegiantTraitor no it doesn't work like that. Look it up. The volume is four times but the surface area is only double.
I've been waiting for this project.
Hello Cody,i'm from Brazil and a Chemistry Techinician, and you are a inspiration to me.Thanks man,you are awesome.Your videos its so greta,I cant stop viewing.
Next video: "Making a fart gun for April Fools!"
“if you’re watching in the year 12,018” lmao
oh man,exactly what I was looking for. I should've known Cody'sLab made a video about it
Dang Cody, I remember when I first found your videos and you only had around 100k subscribers. Now you're almost at 1 mil. Keep up the great work!
ian walker I remember when he was at 10k.
I subscribed when he was around 1,200 :p
As a man of science I think you should fully commit to the metric system :)
Bavarian Steel do you know how hard that is when you were raised using another version
Only 3 countries on Earth refuse to convert to Metric. While the rest of the world moves forward, those places remain deeply rooted in the past, unwilling to grow and advance.
Drew Black, your comment is ironic, considering The U.S. Has (officially) Been At War, for over 90% of its existence. American historian Christopher Kelly and British historian Stuart Laycock are the authors of “America Invades: How We’ve Invaded Or Been Militarily Involved With Almost Every Country on Earth.” They define “invasion” as “an armed attack or intervention in a country by American forces.” There are only three countries the all-mighty-usa has yet to invade.
So, how is that for minding their own business?
Marty.R Woodcock my g why the fuck do you put not adjusting to the metric system to not advancing?
Isn’t the United States one of if not the most technologically advanced countries in the world?
And do you watch rick and morty by the way?
Why bring war into a conversation about how you can’t keep your mouth shut about what system other counties use? You just sound butt hurt for really no reason.
Marty.R Woodcock the History of your country is poor, really, really poor compared to the History of the Great European Powers like Portugal, England, Spain and Italy, not to name more. Your country is a crying baby like you!! That wages war when it doesn't get candy!!! Just Grow Up you shithead.
cody are you keeping up with your grades?
didnt he graduate
He graduated
I am literally 2 classes away, they are not offered until the fall, and my grades are not good enough to transfer schools. so frustrating.
Why the bad grades Cody? You seem plenty smart from your videos, just slacking off on your work or what?
You might look in to whether you can take the two classes somewhere else and transfer the credits to the school you're attending.
I don't understand a lot of stuff you do but it's still entertaining.
Your "continuous feed" system is a crude version of a perfusion bioreactor. They're not as common as batch reactors in the biotech industry, but they're becoming more and more common. Nice work, this was really interesting!
I was looking for a recipe for chili
Cody can you do a video on Fluoroantimonic acid because it's said it has a ph of -31 but the lowest ph is 0 I don't get it
Empolyon 2 the lowest pH is not 0. pH is basically -log of the concentration of H+ particles. So pH=-10 means 10^10 moles of H+ per liter.
***** you just explained what my chemistry teacher can't thank you very much
Contrary to popular belief, some things can have a ph of less than zero and greater than 14.
Empolyon 2 there are two ph scales (though I forget the name of them) one basically says how many protons are donated per atom/molecule (I can't remember which it's been a while since I've checked) and the other measures the ph that the acid acts like even though it's not following the original definition of ph. On that scale it is -31 but on the other I think it would be 0
Hey Cody, nice project, but as a microbiologist, I have some tips to improve your bioreactor:
First of all, since your feed tube seems to be open to the outside, oxygen will continuously diffuse into your bioreactor slowing down or even stopping anaerobic processes. Might be a good idea to attach a lid to it.
Secondly, it would have been so much more time efficient if you´d just jumpstart your culture with glucose to enrich the biomass concentration.
The idea of your manual magnetic stirrer is a step in the right direction, but if you really plan on having a decent efficiency you need a continuous homogenization with a batch this size. (Just had an idea of maybe implementing a sterling engine stirrer - since you are already loosing energy due to the large heat gradient from the barrel to the garage/outside. Might as well use it, but I'm no engineer so it could also have not enough power).
Your feed composition looks ok, but next time please try to break it down into smaller bits. It significantly increases the bioavailability (due to surface area, diffusion efficiency etc.).
And finally, if you have the possibility to heat it to around 36°C (97°F) do it, temperature makes a big difference if it comes to metabolic activities. But you might actually not have to heat that much since the reactor itself will produce a significant amount of heat.
That´d be all that immediately came to my mind after watching your video.
If you are interested in further ideas/discussion I'd be happy to lend my expertise.
Cody ya freak love your stuff mate keep it up
Really going for the extra 10,000 years aren't you lol
12018 HE (human era) is also known as 2018 AD/CE
Can you say the temperatures please also in Degrees Celsius :) ?
FilmHero 90 degrees f is about 32 degrees c, 30 degrees f is about 0 degrees c. that should be a pretty general way to figure out the Temps he is talking about
FilmHero the range in the video was roughly from 2-35 degrees C
just divide by 2, close enugh. ;)
More or less. Thank you ;)
Cody It would be more like subtract 30 and divide by 2
!00 F=~38 C vs 50 C 12 degree error in Celsius is substantial.
but 100-30/2 is 35 only 3 degrees (C) off.
If they set their Cesius thermostat to 50 they will cook the poo and likely kill the bacteria they want.
As values (of F) get closer to zero the estimate gets more accurate.
So this is a kind of bioreactor. I learnt about these in uni many years ago, very smart design this. Not sure how sensitive the bacteria is, but you might gain greater efficiency with a radial impeller of sorts. There is a bit of information out there on the different kinds and what might be more suited to an anaerobic environment like this.
Good work!
Wouldn't it make a horrible smell whilst adding new more poop, also wouldn't the outflow of gass also make a bad smell?
Surprisingly no, it is well contained and once it is running properly the gas coming off it can have a sweet smell to it.
That sounds rather counter-intuitive
Cody'sLab never thought manure would smell sweet , and by the way humans don't produce methane are you sure cause my dad used to remove the porcelain from the royal throne.
Could you try to Crystalize the Methane?
Cody something that hopefully will happen before the Fourth of July which is also a goal of mine and hopefully for you is to get 1 million subscribers and I love all your vids Cody thank you for uploading them
Getting very close to 1 million! :D
Hey Cody, When are you doing another mine video?
Why not use some liquefied nitrogen to purge the oxygen from the chamber?
because most of the oxygen is dissolved into the water. to fully purge it I would ether need to boil the entire mix, pull a vacuum, or add chemicals to react with it. None of those options are very bacteria friendly.
Bogdan Belcea don't question the geniuses ideas
Cody'sLab Great videos keep up the good work Cody, you're awesome! Can't wait until the next video XD
Kieran Edwards that's the first step to never improving
Going to have to call BS on the premise there's more oxygen dissolved in the water than in the air. It would have to be virtually full for that to be the case.
you should make videos on the chemistry behind growing plants. Anything from the pesticides used to your own soil. What can get rid of pests and help the soil including ph levels.
I was responsible for a compost we had set up in our garden for a couple years. I can _smell_ this video
hey cody is there a address that i can send you stuff i want you to examine and experiment on
also can you continue you rocket project
Jacob riddle try sending him an email
oh nevermind he has a po boc adress in his info box on the channel
Arjen Hartink ok
Why do you need nitrogen in a methane generator?
Because the bacteria still need nitrogen to grow, even if it isn't necessary for the methane itself.
fejfo's games I think for the bacteria
Neandercatz How would adding nitrogen-rich chemicals keep the oxygen levels low?
I made a mistake. I thought that he added gaseous nitrogen to blanket the mixture. He actually added that batch because it would give more methane due to the carbon. The nitrogen compounds have no role.
Neandercatz The nitrogen is critical for maintaining the microbial ecosystem.
About time for an update
I like your partridges
WHY WOULD SOMEONE PUT LEAVES IN IT?
It was a high speed composter, there where a lot of leaves around that people wanted to get rid of, and I was on break so nobody could ask me if it was OK. It could have handled the leaves if they where mixed with chicken poop and added slowly.
Hey Verlisify
verlisify follows cody... that's new :0
Your opinion doesn't matter over here!
Can't you just use trash for this ? Like banana peel, rotten potatoes/tomatoes etc ? Like any organic remains ?
You could, but it wouldn’t compost as well
Mihai M or shit
The bad smell from most of those doesn’t come from methane it comes from sulfur
A digester works best between 90 and 105 F, and the bigger the better. If the temp is too low it will not work, if too hot it will kill the anaerobic bacteria. The other thing is that it needs to be a process that keeps oxygen out, and the resultant gasses are methane and CO2, then the material that is used up can be used for fertilizer in the garden. Also it is best to have a small heater, agatator, and pressure relief set at 2 to 15 psi but less than half the pressure that the container is rated for.
The wire mesh floor will hurt the rabbits feet and cause problems, you might want to change their housing. Also they could use more space. Love your videos, greetings from Finland
