This is the first DIY I have seen where they were actually storing the hydrogen and oxygen. I subscribed. I was just blown away with one detail after another. The inexpensive but effective construction, and just the whole fearlessness this guy has. He knows what he is doing.
Tore, I've breathed in hydrogen many times and the pitch actually ISN'T that different from helium for some reason. It does make your voice go higher than helium but not as much as you think. I can't explain why. I guess I am insane a little bit. It's not nearly as dangerous as breathing in a hydrogen / oxygen mixture... well, I take that back. It's actually QUITE more dangerous to breathe pure hydrogen, assuming there is no source of spark, because you're depriving your brain of oxygen. A hydrogen/oxygen mixture would not hurt your brain but a spark would cause the flame to flash back into your lungs and you explode.
I'm not really sure on that. Yeah, what I'm doing isn't safe. The best thing would be a helium/oxygen mixture :) TOTALLY safe. That's what deep sea divers breathe.
I have seen large equipment tire inner tube used as a low pressure accumulator, remove the schrader valve, and a tee fitting used as a input from the splitter to the accumulator and outlet to your compressor's cylinder input. You might also consider adding joker valves on the input and output sides of the tee fitting (not the tube leg of the tee)-(found on the fuel return line in a modern fuel injected ford- in the gasoline tank) Place the fully deflated "accumulator" at a higher location like up the hill or on the roof and when it inflates slightly then have the compressor turn on. Also since the accumulator will become lighter, you could use a scale to control the opening and closing for the compressor circuit. You could use a decommissioned (red tagged) oxygen bottle from a gas supplier ($10-$15) as your H storage (Repaint red and mark it as Hydrogen fuel) as they are built to withstand extreme pressures and external abuse. (your HF compressor could never get an industrial O2 bottle into danger zone because of pressure as long as all oxygen is first purged and never allowed to intrude.) Finally you might consider doing a video showing how you can use a 9V battery to start steel wool on fire then step it up using only O2 ,step the gage of steel or start on a thin edge,it will burn to the point you can cut 1/2 inch steel or more with the right tip and O2 volume. The steel and carbon are the fuel , heat and O2 is you need to cut steel of any thickness. Cody's plasma cutter. Thanks for the great vid. PS keep the oxygen in separate storage way away! Don't store any more than you need. As for the hydrogen, store in a shed with a ridge vent!
Have to say Cody your videos are a really breath of fresh air, opening up science for everyone to understand, i really hope you get some serious backing for your future projects an inspiration to us all. :)
Just to remind you, inside the yellow compressors are brushed motors. Very dangerous! Even in saturated atmospheres. Anyway, the whole setup is a bit messy, be more careful, make it nice and clean.
This is great to see all the dots joined up and an actual working prototype system. Would be fun to close the circle and see the condensation (exhaust) from the combustion, and have it drop back into your water tank
I know you don't need to hear this because you already know but... you have one of the coolest channels on youtube! I mean it truly! I just found your channel recently and can not stop watching! love the black powder vids and the series on precious metal refining. thank you for sharing your knowledge.
one of the best channels on youtube, btween this kind of stuff, the mine, the refining metals, the bees. all around good stuff, always learn something new.
That's a really good idea with those compressors. I was trying to figure out how I would go about compressing the gas, but never thought of putting it in a bag.
yeh, i was like, wait, air compressors suck IN air to compress it, thats why he has bags :O! so the compressor can suck in gas instead of air :D confused me to start
+Forget2BHuman I see what your saying, yes obviously a compressor compresses, but Usually there is no standard fitting for the intake of the compressor, just never thought of putting it in the bag.
Cody doesn't mention this, but he probably sprayed out the bags with a little water first, to add some humidity to the setup. You've opened a new trash bag and felt the static. Bad idea around one flammable gas and one explosive one.
Now you can build your own spacecraft and survive (at least in the vicinity of the earth/sun cause of solar panels) indefinitely :). Well, you might need some food too.
+TheZswader Not only no. Even tho it is popular to say that YES it is a VERY clean fuel BUT during the conversion you loose materia in the burning process, Eventually you will run out no mater how slow.
The first video I saw of yours was the magnet in your finger so I thought you were kinda weird/scary. I have been watching for over 2 years now. Love your account! Still weird, less scary!
Cody I think ur extremely bright and hear you are just a college student in terms of your academic professional progress so far! wish u the best, sir! hope youre an engineering major! large firms would love you!
I noticed in the second series using your homemade torch, to test for leaks, you were going to dunk the tank in water. In the propane business my brother figured out something similar to their propane leak testing solution by making his own. Use an old saline eye drop bottle filled 3/4 with water and just ad a few drops of liquid dish soap to the water. Shake it up, you want fewer bubbles in your solution. Then spray it around the new welding and valves to check for leaks. If you find one it will bubble and pop, bubble and pop. Hope this Idea will help you with your leaks.
Cody and Primitive Technology guy are the people that probably could survive an apocalypse without even noticing. They would probably recreate the whole civilzation out of rocks, sticks and some acids.
i really love to see that. As a Teenager i built a similar Oxygen-Hydrogen-Seperator with plastic bottles, hot glue and graphite electrodes (these worked surprisingly well, try it maybe!); powered by a laptop-energy supply, but i never got it to withstand pressure. If i had a compressor i could have done it your way, but i didn't had one and neither got that idea. Cool man :) i loved to see how well the torch itself worked then.
CODY YOU ARE A DAMN GENIUS SPLITTING WATER. This is insane lmfao you blow my mind every time I watch the next video. If the is ever a Zombie Apocalypse I'm coming to find you and I'm in CANADA 🇨🇦 but I will try and find ya cuz you know almost everything lol ok im done yapping yes I know this is 5 years old but there is ton I have missed so you will see me comment on a few videos 👍😎🇨🇦👍😎🇨🇦👍😎🇨🇦
Cody, hope you planned safety margin for hydrogen embrittlement of the pressure vessel. A thin baked on slip coat of clay inside could stop most of the danger of embrittlement and all you would have to figure out from that point is your fittings.
That's a wonderful discovery of ways to survive the Mars landing . Yes , we do appreciate you but the force appreciates you more . Give life to the lifeless Globe in the space . Good luck
was halfway expecting something like the picture in the August 1980 National Geographic article "Water: Our Most Precious Resource." I would have loved to see it first hand, but by the time I was born they had a new well. Otherwise your experiment was very cool.
again, something that would solve a lot of your problems is a check valve, such as in your output so you don't have to worry about siphoning acid into your collection bags. you can buy one or even make some, i'm pretty sure there's a few diy projects out there for them.
I saw a video of someone making methane to use in there house for heating and cooking. they trapped the gas in two drums one larger than the other. the largest drum contained water the smaller was inverted into the first with a BARB FITTING/ VALVE when gas was needed they weighted the trapped gas in the inverted barrel to create pressure
Improvising at its best. I'd never think to use a $7 harbor freight special air compressor to obtain O2 and H2. This is some greatness right here. My humble two cents: (1) Punching balloons would be great for hermetically sealing your compressor setup. (2) Adding Diatomaceous Earth to your hydrogen container will add the almost infinite surface area needed for the very slippery H2 to cling to, thus improving containment. Now if we could get the big people to scale this up around 2 billion times we'd be set. Planet Earth would live! Cheers
Cody, awesome vacuum setup. I have a HHO system as well. I am really interested in how you split the gasses to keep them "clean." I commented on your torch test video before I found this one. I would like to swap some ideas if you are interested. Keep up the awesome work.
Awesome Job Cody....Well, I"m a ER/Critical Care pediatrics physician and my favorite pastimes are blacksmithing, welding, and fabrication. I see many many markets for home H/O gas production apparatus. Given that coal is getting harder and more expensive to come by as a blacksmith...we are now paying upwards of about a dollar a pound including shipping for quality bituminous coal. Welding gasses such a MAPP, acetylene, and even propane is getting quite expensive as well. What are the burn temps of hydrogen compared to the aforementioned fuels? And would it be feasible to generate an H-H-O gas forge to take the place of a propane forge? Needless to say, I am very impressed with your videos....and to be honest, I just came across them a few days back and have been binge watching them while recuperating from getting hit head on. Thanks so much Cody. You and your parents should be very proud of your curiosity. It will definitely serve you well.

Very interesting set up. The only thing I'd change is to move the whole lot outside. I used to work in a lab with hydrogen tanks and we had to monitor constantly for escaped hydrogen. The problem is that it floats up to the ceiling and stays there. Even a small leak will slowly accumulate and then blow the building up when you are least expecting it.
+Robert Nugent Working once or twice without exploding is, I feel, probably worse than it exploding straight away. It'll lull him into a false sense of security. The bag of hydrogen on it's own I don't think is much of a problem but he's got it right next to a bag of oxygen. The setup is an accident waiting to happen.
+Robert Nugent The flimsy plastic bag is a major safety feature for any DIY-er. If anything ignites those bags will just fall apart and make the explosion dissipate very quickly in all directions and without shrapnel, if that happens in a very constrained container there would be limbs decorating the walls. I do agree however this shit needs to be done outside with as much distance from the aperture as possible, brushless motors also wouldn't hurt.
Awesome project. I wouldn't recommend trying to live off of that oxygen you produced though; the stuff's bad for your heart and lungs if you don't have a filler gas with it. Keep making videos, Cody. We all enjoy seeing your projects come together!
Ive come across videos where they make "hydroxy gas" in which the hydrogen and oxygen are mixed and stored in the same canister which is a literal time bomb waiting to happen. Thankfully you have the presence of mind to keep them separate.
There will be trace amounts of whatever material is used to lubricate the pumps in both streams. German airship crews had a terrible mortality rate in WWI until this was realized and they converted to oil-less compressors and they stopped dying from asperating oil. You *might* be able to make it safe(r) with yet another hooka system. it'd be a design challenge, though.
this would be good for light oxyacetylene welding and brazing, and not much else, i doubt you can cut anything worth cutting, but still quite impressive
That was misleading, you made me think that you were oxidizing H2O, when instead you're just oxidizing H2 that you extracted from H2O through electrolysis. Which is still cool.
to properly evacuate a cylinder you have to run a vacuum pump to nearperect vacuum to get as much moisture out then fill them with nitrogen to absorb any lingering moisture then run the vacuum again. this method could be done multiple times till satisfaction. or 3 times with is called a triple evac.
Awesome , I'm glad that You came back to the HHO torch , HHO torches are Amazing , if You get the mixture right then You can turn steel into puddles and melt cinderblocks into what looks like Lava lol . You may want to put "HHO Torch" in the name of this video to catch eyes . Super Cool Man , Stay Safe :) .
