I often thought of putting myself into an airtight container with 20 mature sansevierias, mature sansevierias produce roughly 5 litres of oxygen an hour, which is a heck of a lot for one plant, and humans consume roughly 50 litres an hour, so 20 snakeplants should theoretically be double the amount needed, I'm honestly so happy that this has been done for real! Thankyou for quenching my curiosity.
Awesome! Really fun way to raise awareness of some pretty serious issues. I'm thinking you should do a David Blaine style 'live in an ice cube' series to teach us about rising sea levels. As the ice melts it could fill up a container of Lego men who all slowly drown. (I hope you're writing this down!) ;)
Cool experiment. I like that you had an O2 and CO2 monitor. Did you figure out that the plant volume you had was way too low? based on your body size and energy use, you would need a cube of around 250,000 liters with a green leaf surface area of 190 square meters. Still a valid experiment.
This has nothing to do with the plants, but I'd also like to mention the O3 and -ions created by the electronics, and also gases released flatulence all completely changing the makeup of his air. Even the new plastic he wrapped the box in off-gasses chloride compounds and the silicone sealant will off-gass acetone and other VOCs
@@zyn5394 Yeah but there are way to few plants to make it stable, so even if you have plants the dangerous thing is the build up. A room that size has enough oxygen for a person for a few days
@@generastanisawbojowy21 first of all, when did I ever even say it was man-made? and second of all literally the entire independent, peer-reviewed scientific community and knowledge-base disagrees with your sentiment.
Hi Kurtis! I have to know, has this project been included in any science publications? I would like to cite it. Please keep up the fantastic work! Thanks, from an MSc physicist :D
Hi! I don't think its in any academic articles at the moment. It made news in sources like the BBC (link below)... But if you're looking for similar studies, I know there was quite a lot of papers generated from Biosphere2 in arizona, which did this on a much larger scale. Cheers! bbc.com/news/world-us-canada-45965027
This seems very similar to the Biosphere 2 in Arizona! The University of Arizona is currently using the facility for research purposes, but it's only been used twice for purposes similar to this video. Love the video by the way!
You have an incredibly friendly and down-to-earth vibe and I love that:) and of course, your videos themselves are very well made. I love science too:)
I used to design in my mind an insect proof sleeping box with a see through top so I could have the illusion of sleeping under the stars without the intrusions of suburbia in a disadvantaged area full of impulsive, largely damaged people and their likewise animals. Eventually gave up because of my lack of practical ability and the dollar cost of getting envirosound materials. So I am truly enjoying this video. Part Two awaits.
I dreamed about doing this after watching a video about Biosphere2. Good for you for doing it and drawing attention to Global Warming. I'm going to show this to my 7th grade Science students after they learn about Photosynthesis and Cellular Respiration. Thanks Kurtis!
Maybe it's inconsequential but the human body breathes to purge CO2 not to acquire O2. This is why CO and CO2 atmospheres like those found in some caves or industrial accidents can cause immediate loss of consciousness without notice.
The plant survived because in the morning it took in carbon dioxide and made oxygen and at night it took in oxygen to make its own carbon dioxide, meaning that the plant doesn't need to be set out of the jar since it already has its own air.
As a professional drive im always curious what concentrations of CO and CO2 im exposed to and what effects they might be having on my ability to operate the vehicle. Would be interesting to get data on what kind of CO/CO2 levels im exposed to on freeways and in truck stops, might be worth me buying some gear and collecting my own data. And of course im casuing some of my own issue here when i have to idle my truck to stay comfortable enough to sleep/not die.
After watching this 3 part series I wondering two things: 1. How hot would it get in the "jar" in full sun and would you be able to stay there, and 2. how long could this experiment have lasted had the sun come out? Some day I want to recreate this experiment in my backyard.
@@fazejaanus PC isnt just better than mac for gaming. It's better than Mac OS and its whole platform for a lot of things, the large majority of times. Whoever is unfortunate enough to buy a mac just got scammed.
Different strokes for different folks. Some like the very simple OS. And most like their computers to not be insanely high maintenance. And everyone likes their computer to last a long time without slowing down and having problems. My brothers (now mine) $1000 desktop pc (ik its not as much as most apple laptops, but it’s high end, not like a $400 laptop compared to a $1200) and it is much slower than it used to be and I will say that Microsoft 10 has had no problems, while 8 is a dumpster fire for my laptop. My dads desktop apple computer with similar specs to my desktop pc is way faster after a similar period of time. Of course there are ways to speed it up, but it used to get like 300 fps and gets less than 100 now. And it was just recently whiped when it was given to me.
im @ 1:24 into the video. with enough flora theoretically the O2 to Co2 should cycle... although nitrogen is super important to breath breathing pure oxygen isnt the best for you. Super Creative ide a man hopefully this goes viral
I'm from Tom Scott video, and it turns out I already subscribed to this channel so... Yeah... (actually I already have a feeling that I already subscribed to this channel cause I recognize the one take universe history thing)
also an anolog oxygen sink would work well, this science may be difficult, but we know a lot of things from probing the human body often, also, like growing mushrooms is good for plants because of that behavior
although the ppm of CO2 is rising its partiality(%) as part of the air is not changing with the time. So we still have 0,033% of CO2 in the atmosphere and 20-21% of O2. The bigger problem will be, if the air pressure will be changed, in this case, the O2 partial pressure in the lungs will be too small for the exchange of O2 with the blood
@@seigeengine yes, what if the percentage of O2 in the atmosphere? you do realize that it is still between 20-21%, yes?! and N(nitrogen) 78%, yes?! So if there is more CO2 percentage, why the other gases are still the same as they were, even when there is more CO2? If some gases go up others need to go down.
I've had a biosphere idea for 90 feet which in on 1 acre of land.... Hope that we can grow something else like a fruit tree so now that I have the fan on in my nano-city itself has had to be placed into a prefab folding home like vistabule weights maybe 1.3 feet taller then 5 x 5 if minimalism was actually a thing??? but great job with the Utopia thanks 👍
What about food? Are you growing edible plants? What are you gonna do about bathing and using the bathroom, for that matter. Are you going to take periodic breaks? Doesn't that defeat the purpose of the experiment?
