"sky rocketing prices".... You should be ashamed.

Well then the real question is how does the ISS get water?

If you don't Pee enough then--- Urine Trouble!!!! 😂😂😂😆

"howmanypeopleareinspacerightnow .com" i see what you did there... that tickled my inner Vsaucer

Anyone that has seen “The Martian” knows how this works.

Hey VSauce Micheal here!

Interestingly the filtration system on the ISS is so advanced and thorough that even though they are recycling their urine, it’s a lot cleaner than the water you would drink from a tap or even your average water filter

I read this as "how does isis get oxygen"

This video generates so many more questions than it answers. Kinda like the way Earth's plants, with only .2% or so CO2, apparently generate the 20% oxygen we breathe. I think it might be all magic, and printing money, which is also magic

I absolutely love the way you structured this video. So concise, so clear. Great job! :)

You don't have to grow plants to turn CO2 into O2. You can use the Sabatier reaction together with hydrogen to turn CO2 into water and methane, and electrolysis to split the water into hydrogen for feeding back into the Sabatier reactor, and oxygen. They do this on the ISS. I don't know how efficient it is because they vent the methane which contains much of the hydrogen atoms you need for a fully closed system, but they could potentially turn the methane into hydrogen and carbon, feeding back the hydrogen into the Sabatier reactor. Then you just need to supply food for new carbon, and energy that you get from your solar panels, and perhaps some water to account for inefficiencies, but the food will already contain some water anyway. You can also do electrolysis of CO2 directly, splitting it into carbon and oxygen. They're planning to run such an experiment with the Mars 2020 rover, called MOXIE.

I very much enjoyed your split screen Data/Calculation! Super tidy, super clear. Nice job!

that was amazing as well as very informativ, thank you!!

I love the mathematical and engineering approach like this, good job!

I love that you place those labels in the bottom left!

Really hats off for the superb explanation with realtime data.

Next question: what does the ISS do with the 700g of hydrogen?

but.. doesn't that just must mean they're shipping really expensive water instead of really expensive O2 tanks? if the water isnt being regenerated from CO2 and H2 it isnt a closed loop. soooo....

this is not even part of my field as I am in the hospitality industry but I found this very very interesting and ive been addicted to this for months

Interesting and clear, subscribed!

Ideally, you'd have a machine that separates the oxygen from CO2 in the air, and condenses that carbon into construction/patch material. That or plants. Plants work too.

Awesome video! Like and subscribed, you have a decent english accent, but i immediately heard that you were Dutch

Looking forward to more!

Was LITERALLY just thinking about how do they do it, and then this pops up on my recommended 2 years after it came out

I’m way late but I didn’t read it right and thought it said “how does isis get oxygen “ 😂

Cool. Looks like a Hollywood basement.

A favorite astronaut exclamation, 'I am pissed off with this air'.

This is seriously amazing!

*The Reason I Clicked On This Video:* _I Thought I Saw ISI In The Title_

the cost for launching 1kg with a spacex falcon 9 is $6000 not $60000. Based on, that the rocket costs 60mio per launch, and the CRS-Dragons (the cargo craft) weights ~10tons (you can read everything at the launch history in wikipedia). The Falcon could theoreticly launch >20tons ins LEO, which would make the $/kg ration even cheaper, but the ~10tons CRS missions were the heaviest so far. I know this is the overall weight at the launch (so including the dragon cargo craft) but even if that weights 5tons so 50%, you are not at $60k/kg..... wtf Except that, really interesting. Was for my also a question that i never really asked myself, but as soon as i read the title, i couldnt resist :D

They could store the hydrogen to let the ISS move through space by releasing the hydrogen. The same happened in the time of the space race when they made a space suit with MMU (Manned Manoeuvring Unit).

Interesting presentation. Thanks for sharing

So what do they do with the hydrogen? Vent it? Store it? For someone calling himself "The Engineering Guy" you don't explain things very well. Saying it, "should be... taken care of" is extremely vague and pointless.

Anyone who thinks the ISS is fake, or earth bound, then feel free to come and observe it in detail using my equipment?

Thanks for answering the question with the thumbnail

Thanks for the great explaination 😃

And some people thinks that the world is flat. What a sad creature.

Hey vsauce michae... MrengineeringGuy here

Me: 'sabotaged oxygen' Everyone on the ISS: *confused screaming*

You need a good background music and a microphone... Your explanation for the concepts is awesome.... And those statistics are good.. Subscribed this channel at 2000 subscribers.. looking forward for a great future ahead for the channel...

No engineer would say "one point twenty-three volt" !

could someone please explain why there are like 438972359 comments saying: yeah they just open the fucking door to the studio..... whats with all the hate?

The ting I now is a few of my brain cells exploded 🔥

Nice video I loved it ❤!!

The need to grow Cannabis 😉

One question tho... as far as I understood, to form oxigen they're also using another not renewable recourse in space: water. How do they keep the process going without having the same problems as with oxygen?

I... didn't know I wanted to learn this. NOW I HAVE TO

Subscribed - Great video

I always have this gut feeling the ISS will one day come crumbling down it's not safe there

actually, the hydrogen generated from adding the electricity to the water is then combined with carbon dioxide (what the astronauts breathe out) and is turned back into extra water for the astronauts to drink! so efficient!

Thank you very much for the information

Best answer that one can get to this question

Your accent sounds Dutch, South African and German at the same time

The trolls in the comments...

Before we colonize mars, we’re gonna need some sort of system that can turn carbon dioxide into oxygen until we can get the plants sorted out

The ISS gets its oxygen from the same place we all get our oxygen from.

So how much does the OGS cost?

You said "how many people are in space right now.....dot com" with the same style as Micheal from Vsauce doing a DONG video.

Thank you this is great success!

Boi this is quality Content. No Joke i expected at least two more 0's after your sub count

OXYGEN SUPPLIED BY THE GUYS SWIMMING AROUND IN THE WET SUITS

Clickbait thumbnail

I suggested NASA to drop a long tube back to earth, now they are forcing me to become the lead engineer. I politely declined.

Great video thank you

Hey can you Do a Video on the magic seals they use on The ISS :)

It's easy, they just open the vents to the basement in Hollywood.

Cool info..thanks

I shouldn't have clicked on this I already knew how it worked now I find flat earthers on the comment section.

Lower the tanks into the pool.

First again!

Don't give them plants because I always forget to water them. Oh and that water machine is no good, dahhhh, its even more expensive to send water to space. 🧸

Anybody ever hear David Adair’s recordings regarding tomato plants in the first space station? So much oxygen they had to jettison the plants.

They get it from the air, duh. Smh I'm 13 and already know more than astronauts with my iq of 156

What does the ISS even do to help the Earth?

1:12 imagine using this for scuba diving you could stay underwater for a very long time without coming up for air

Nice video.. I think you said how many plants would be needed to support the 6 crew, but I missed the words you said. Is that picture of the plant room actually from the ISS? Thx

Haha, another episode of National Academy of Space Actors.

Iss is on earth.anyone with a brain knows it.

This reminds me of that person who make their own ecosystem in his helmet 😂🤣😂🤣

so how did you calculate the spacex and other cost per kilo of O2, the dragon can deliver 6,000 kg and nasa payed around 90 mil for each mission which would mean its 15,000 per kilo, did you factor in something else too like the weight of containment vessels?

Zero people in space, do you really believe these clowns are flying around the world @17,500 mph? Really? you're easily fooled aren't you?

They gotta setup a grow tent for some space kush. Its outta this world man.

People often underestimate how interesting, fun and amazing science can be. Most people have painted a picture of scientists and engineers being boring nerds. This is simply NOT true!

I wonder what the most compact way of getting oxygen from CO2 is? An electrochemical reaction (either to take the carbon out of the air, or to take the carbon out of a carbonate or other ion in solution) would be ideal for having it be reversible, but I know of no aqueous chemical reactions that produce solid carbon. I assume you’d need to do something more like a fuel cell, or just use algae or cyanobacteria in some sort of capsule with integrated lighting. Using lithium peroxide’s reaction into lithium carbonate works short-term, but it depletes. Note that some chemistries of CO2 absorbers (including LiO2) produce oxygen gas as a byproduct, so you only need to electrolyse half as much water.

Historically no. The massive Bio-Dome 2,even with it's massive jungle and water features was still not able to supply the small team with oxygen. They had to open a window.

Very interesting - thanks :)

Thank God he never charge me for the price of Oxygen and water.

thank you, this was very interesting!

It completely depends on who is sending your 1kg into space. Different rockets have different cost per kilogram, and this varies from a couple thousand dollars to tens of thousands of dollars. Generally speaking, larger rockets have a smaller cost per kilogram because they can launch more mass with a smaller amount of [expensive] hardware per kilogram launched. For example, the SpaceX Falcon-9 has a cost per kg of around $2,500 to low earth orbit, whereas the much smaller Rocket Lab Electron rocket has a cost of around $22,000 per kilogram. Of course, cost per kilogram also varies depending on the destination of that kilogram. Getting mass to other planets requires a reduction of the total mass sent, which therefore increases the price of every kilogram sent.

That moment when you accidentally connect the methane tanks instead of the oxygen tanks

You do know that the ISS has a pressure altitude of 60,000 ft. And typically that would lead to hypoxia but we convert water into pure oxygen, the higher concentration and high altitude allows the oxygen to bond to the blood but not enough to poison them.

New sub!

Instead of studying chemistry, I watch your videos.

The start of this video was very Vsauce DONG like

Good content keep it up i can tell your gonna be a sucess

I am thankful for the air the I breathe for free

Finally a someone answers this question!!!

Omg so interesting! 👍🏻

I thought the ISS had a super advanced machine that could take Co2 through ventilation split the compound into o2 and c

I hope you come back and make new videos! These are great. Subbed 🙂
