Ok
I got one for my brother on his birthday and he loves it! Thanks ❤
Got the Rotary one its really good quality 👌
Why don't you make v2 rocket powered car
BRING. BACK. THE. MOUSTACHE.
I like the foam + KMnO4 mix. Very simple. The downside that I notice is that it burns up, and I doubt you're getting full use of the O2 from that tiny amount of foam fuel. If you want to get that hybrid rocket effect I think it would be better to have a non consumable catalyst and a solid fuel further down the line. For a similar material to your flower foam that is less prone to combustion you might want to look into intercalated graphite. It's possible to intercalate graphite with KMnO4 and I bet it would make an excellent catalyst in that state. There's a paper I replicated at one point that turned graphite powder into an excellent low density foam titled: "One-step room-temperature preparation of expanded graphite". A little KMnO4 in the mix would probably make it into an excellent catalyst, though perhaps too fragile. Another option might be to follow any number of intercalation methods mixing a little KMNO4 into concentrated sulfuric acid, and soaking graphite in the mix for an hour or so. A very durable, flame resistant, and porous option that might make a good catalyst is treating carbon felt in this way. Carbon felt is a wonder material in it's own right and might work for your purposes as is once soaked and dried in KMnO4 solution.
I'm curious what the actual reaction is here. Like, is it just a physical reaction with the shape of the KMnO4? Or is it used up some how in the reaction?
Thank you for the advice Ben ! Can you please send me the paper ? integza@gmail.com
@@integza Will do!
You seem to be well informed.
Could you use hydrogen peroxide as a regenerative coolant?
Pulse jets get stupid hot and it just goes to waste.
If you ran fuel rich in the combustion chamber and then had the highly oxygenated steam go into the exhaust, it should sort of act like an afterburner.
At least that's my hypothesis.
Would you even need a catalyst then? Would heat just do the job?
@@integza The channel Explosions and Fire or Extractions and Ire (i cant remember which) has a great video about concentration peroxide. You might be able to use some of his methods.
@integza, you can try vacuum distillation to concentrate the H2O2 solution. You can then probably use a temperature close to room temperature (around 30C) to boil off the water out of the H2O2.
I was wondering if you could use a vacuum chamber to accelerate the process.
Came here to say the same thing
Yep, thats exactly what I was thinking. STP, vacuum chamber at lower temp, or higher temp.
....
Will also change temp at which H2O2 will boil, so may cause decomposition... not sure how those bonds break, from boiling or from temperature... maybe the same process.
Im not a chemist.
I think vacuum distillation is certainly a good idea. However, as most medium and low-vacuum pumps are oil displacement devices, I would also invest in any sort of a cold trap (could also be dry ice + alcohol if you don't have easy access to liquid nitrogen) to condense and trap the distilled water befores it pollutes the vacuum pump's oil.
I was about to comment the same thing. It would work just like a refrigeration system.
You may want to try that evaporation under slight vacuum, given lower pressure it might speed up the time it takes to concentrate
That's exactly what I was gonna say. At 60 °C and say half an atmosphere it would probably go a lot faster. Probably could get to significant concentrations that way too.
Agreed. The lower pressure lowers the boiling point.
If you want to concentrate the h202 better, check out Explosions and Fire, a couple of years ago Tom has concentrated it to 100% and then took it further.
Isn't decomposition one of the 5 type of chemical reactions🤔? Intezga must've meant its *not a combination reaction* , the type of reaction found in combustion💥.
Video Suggestion: attach a turbine and propeller on the exhause of a rocket to increase thrust, similar to a turboprop/fan in planes.✈️
yes
Of corse it is a chemical reaction
@@WochenendNerds, yea he misspoke, a small price for being multi lingual
Any thing done is a reaction...everthing is a reaction until you get to a carbon atom...oh wait theres reactions there to lol.
Gaffs like that happen when you're tomato-deficient
@Integza, you might find molecular sieves particularly useful for drying and concentrating hydrogen peroxide. It’s used to make products anhydrous all the time. You would need quite a lot of them, and they are reusable.
Nope, they catalyse decomposition.
Hey Integza! Looks awesome! I was thinking something that could help the design would be an improved injector. This goes along with what you said about surface area, where if you can maximize the contact between the peroxide and the catalyst you should get better results. Maybe an injector that does a better job of atomizing the peroxide rather than spraying jets of it directly into the catalyst would be beneficial? I also thought the charcoal/ceramic idea was really awesome and pursuing this could have some interesting results. I think early H2O2 rockets used pellets of catalyst in a chamber, so the chunks of charcoal might be the right idea, trying mixtures with permanganate and maybe some other additives would be awesome. In future videos I'd love to see improvements on this and maybe one day combustion of the oxygen product to make a bipropellant rocket! Keep it up!
Reactions only happen at the interfaces, which is why meshes/foams work better. You need to give the same attention to peroxide. Improve the injector so the peroxide droplet sizes are smaller and you will get a more violent reaction.
Genuinely love how you don't just gloss over details and just tell everything how it is. In terms of catalyst, what if you used acid to etch away silver so that the surface becomes pitted and exposes more area? Kinda like activated charcoal. And speaking of activated charcoal, how does it work with peroxide? I was surprised coconut coal can decompose it
turning wood into coal concentrates a bunch of the solids a tree has...and since every living organism has metal ions in their bodies i presume a bunch of them during the process gets reduced just like in ash from a firepit (the first soaps were made using ash as the catalist for the saponification)...and since coal has a bunch of small pores increasing it's surface, it acts pretty much like paladium on carbon with the small deposits of teeny tiny metal particles...now does any charcoal works? idk...now what i can assume is that since coconut is a seed that the tree pours a lot of nutrients into (including metals from the soil) for the seed to be viable upt to 3 years after detaching from the tree, the concentration of metals on coconut charcoal could be higher than other commonly used charcoals...
Cool video!!! Using steam to power an RC airplane's propeller could be an interesting experiment. Something, you could try out in the future: building a jet engine that has a hole in it. Let me explain: Similar to your Dyson engine, it could have a hole running through the middle to increase the output thrust. However, this time, instead of building the compressor into the handle, you could build it around the hole itself, so you don't need a handle anymore. I've been thinking about this concept for a while after watching your video and would love to see this peculiar jet engine in action!
Integza, I think that if you ground the potassium permanganate into a fine powder, it could then be used as a paint base to spray into the mixture/reaction chamber. This would allow a chamber filled with catalyst coated rods running the length of the chamber. These rods may increase the surface area enough to react quickly. Another option is to coat the injection tubes as well.
An option you could do as a middleground option that's both accessible and interesting for your foam + KMn04 strategy is to create a carbon foam using bread. AvE did a video on it years ago, and it might work for your strategy. Hilariously enough, one of the topics you'd need to figure out would be the optimal bread to use to have the best crumb structure to absorb the KMnO4 and react with the peroxide. Would a dense foam from the dense crumb of a japanese milk bread be optimal or would an airy open crumb from a ciabatta or even airier with pan de cristal be best?
Either way, super easy thing to test, it's as simple as getting bread! Also depending on the results, you could possibly even put the carbon foam to be milled as you did the flower foam. Probably not with an airy bread, but the japanese milk bread can have an incredibly dense and fluffy crumb, especially if you do the method when its baked in a lidded bread pan.
Also fun fact, I accidentally discovered the ability to concentrate peroxide in highschool where I had filled a bowl with it for something with regular household peroxide, but forgotten to dump it and it sat on a shelf for a few months. I found the near-empty dish and dumped it, but accidentally touched the tip of my thumb to the small amount of remaining fluid. Over the next couple hours, half my thumb was white and it bloody hurt like crazy.
Fantastic video, as always! Have you considered utilizing the oxygen generated from this reaction for a second stage? It could burn additional butane, potentially squeezing out more thrust.
Or you could even pump butane into the active reaction and use it to further excite the burning and further expand the gasses
This is what I thought he was going to do by looking at the thumbnail as peroxide rockets have been around for a while.
@@geofrancis2001 i know he basically did that last video when he introduced the concept of a "dual propulsion rocket", except he just burned the raw oxygen and products. Adding more fuel (butane) would make it even stronger than his original concept in LAST video
@@MichanaAlerting it woudlnt have to be butane, the steam should be hot enough to ignite solid fuel.
@@MichanaAlertingsort of an afterburner?
Thank you so much for exploring chemical deposition of metals in your videos! Your method of copper plating the electrode in the bladeless fan episode gave me the idea of using electroplating to make custom PCBs in my apartment workshop, and so far its working well!
Great video! I did catch that 1.5 ml vs 250 ml is 233 times the expansion. It is even greater the open volume of the mixing chamber's volume was not factored in- definitely 250-350 expansion. This is a slower expansion than gunpowder but still very powerful. A gunpowder explosion is instantaneous being quite destructive. This expansion is slow and not so destructive unless the gasses were trapped in a container that can hold the pressure. A gunpowder rocket burns gunpowder slower than a bullet propelling it over time but still a relatively short time for burning. The pressurization of gunpowder accelerates its burn speed. In open air gunpowder burns slowly, almost as long as this chemical reaction rate. In a rocket pressure is released out a nozzle to prevent blowing up by too great and more instantaneous explosion. The nozzle is designed with enough open a nozzle or opening on one end to prevent over pressurization and instant explosion. As a kid I learned that there is a ration of 1/3 to 1/2 of the inner explosion chamber that the gas must have to prevent explosion. Too much pressure on the fuel not released will blow up the fuel chamber.
Really great video, as always! Perhaps a bit of a change from your usual content (but still in line with your channel theme), I would love to see you build a Tesla Egg of Columbus. They are so cool and I can't find a tutorial for one anywhere. Seems like a fun thing to have around to demonstrate Tesla's induction motor. Anyway, thanks for your hard work on these videos!
To concentrate the peroxide, maybe try to do what Tom from Explosions&Fire did, which is using sulphuric acid to dehydrate peroxide. Took him months, but it's worth a try.
I remembered that as well but what he is doing here already seems much better
Would just pulling a Vacuum and boiling it at 60° be possible?
I had success vacuum distilling H2O2. ruclips.net/video/kmWmbz5CPvA/видео.htmlsi=QGgsW80xMm4kFG-P
Also just made a similar comment. First thing that came to mind.
The rocket belt you mentioned in this video. I did the machine work on the engine parts. The catalyst pack in the engine was silver plated stainless screen material. If I remember some kind of stainless steel screen. But it was all heat treated in an oven somehow. I’m not exactly sure of the process. (Not the part I did). But it was very tightly packed requiring a press to do this. Then the engine was welded together. The hydrogen peroxide they used was distilled from 50% solution in a special lab/trailer they built. A very, very, very dangerous thing to do. If I were you I wouldn’t do it. But it’s up to you. Anyway on the rocket belt there was a high pressure vessel containing 6000 psi of nitrogen (if I remember) that pushed the hydrogen peroxide solution into the catalyst pack in the engine. This expanded into two tubes that exited thru nozzles (Designed by my friend). On the end of these nozzles we’re sort of flow directors that could divert the flow for spinning the rocket in the vertical axis. The whole belt/engine hung on a hemi joint on the pilots hack which he controlled by the two handles you see in you video. The whole flight time was around 60 seconds. The pilot had a vibrating devise on his wrist that alerted him of how much time he had remaining left to land. This thing was mainly flown in stunt shows at stadiums as an opening event type of thing. The test flight I saw the thing was very loud. Like a jet plane taking off. The guy that flew it must have had ball of steel. Because when you run out of fuel you fall!
this one is my favorite so far, you are actually a genius.
you've improved a lot. you went from recreating existing designs, to designing and creating a brand new type of rocket all on your own. this is real science. as Cave Johnson from the Portal franchise said, "science isn't about 'WHY?', it's about 'WHY NOT?'!"
Apature Science. We do what we must because we can. For the good of all of us. Except the ones who are dead.
But there's no sense crying over every mistake. You just keep on trying 'till you run out of cake. And the science gets done and you make a neat gun for the people who are still alive. 😅❤
Integza you should try to build a valved pulse jet and compare the efficiency to your old valveless jet
A) SOOO nice of you to give Backyard Ballistics a shoutout! That guys is both entertaining and adorable.
B) You absolutely NEED to effectively use up the excess oxygen. Try giving the flour foam a bit of alcohol, or go back to a liquid mix system where the permanganate is dissolved in alcohol.
This was pretty cool. I liked the explorative and experimental nature of it.
it's important to note that, while is wasn't made clear in this video, the V2 **is not** an hydrogen peroxide rocket, it has hydrogen peroxide driven turbopumps, but the main thruster was an ethanol-lox engine.
I think he did actually say that.
@@thedogfather5445 yes, he did say that the pumps were driven by hydrogen peroxide, but I don't remember him talking about the main thruster propellant, which is why I made this clarification. the video is otherwise very good.
Can you make a video on how solid rocket motors or boosters, are made and how they produce a consistent flow? I know you can buy them from hobby shops but an explanation of how they work would be interesting. A see-through motor would be an awesome video too.
Glad to see you upgraded to the X1CARBON as well I haven't touched my resin printers since I got it with the quality it produces
I love this video. Your journey to find the right material is something I can really relate to. The video is very well put together.
Have you tried Vacuum distillation? The assemblies aren't super cheap but this also isn't the most expensive thing out there and you can for sure find one for a reasonable sum. OR you can just buy some glassware and pull a vacuum on it with a pump and you're good to go. It will affect your ratio since the pressure curves for peroxide and water are different but it'll take out most of the time needed and you'll use less energy it will be faster and you can probably also get higher concentrations with this. You will also save peroxide since you can capture the distillate.
Vacuum distillation of hydrogen peroxide is not for the weak of heart, the closer you get to anhydrous the bigger the risk of explosion is. It's definitely not something an amatuer should try, most professional chemists would be scared
You can use a desiccant instead of heat. Explosions and fire did it.
It's really slow but still take it higher
Best way is to concentrate H2O2 by freezing it multiple times each time the concentration gets higher
Would love to see you build a Jet engine Glider! :)
Hey Integza! Looks awesome! Thank you so much for exploring chemical deposition of metals in your videos! I think you should try to make a particle accelarator about physics!
Bravo adding Also elettromagnetismo to the Cloud from the exit maybe
@Integza Here is a concept for getting better contact between the peroxide and the catalyst:
When you cast plaster, insert a bunch of corkscrew shaped pieces of steel (such as a stretched out thin springs, coated in mold release spray if needed, or perhaps literal cork screws). Then, when the plaster is hardened, remove these corkscrew shapes by unscrewing them out of the plaster. Then, inject the peroxide into these corkscrew shaped channels. As the decomposition happens, any liquid that gets pushed by the released gases won't just shoot out of the channel like it would with a straight hole; any liquid droplets propelled by the gases would much more likely slam into the wall of the helical hole, enabling it to react with the catalyst.
Try this and see if it doesn't result in more efficient use of your peroxide.
Thanks for the cool videos,
Maybe 60degrees temp and some vacume would be worth trying.
A rocket using all the oxygen from the decomposition would be a nice video idea. There will be even more heat and a faster jet at the nozzle.
Better bellow 55°C under 120milibar vaccum pressure to make sure its not decompossing. Dont ask me how i knew it.
Great video! Love to see the progress. I was thinking...in order to concentrate the peroxide, how about a vacuüm chamber? You won't be needing an elevated temperature at all in order to 'boil' water in vacuüm, but maybe combining both principles could yield even more interesting results. Keep up the good work!
The print quality is great!!!
Hi, could you try to make a rocket engine with liquid ergols like LH2/Lox. Thanks, your videos are awesome
Both are very hard to handle, especially lh2. Hydrogen atoms are so small they leak through solid metal
Hi Integza, great video once again! I've been enjoying your content for quite a few years now and still love every video that comes out. Just a little mistake that I noticed in this one though. Regarding the V-bombs. Namely, it is not "Vergertungswaffe", but "Vergeltungswaffe". Vergeltung of course translating to retribution, or vengeance. Keep up the great and informative videos though!!
Small correction. I assume this has been said before me but the KMnO4 does do a chemical reaction with the H2O2 it's a RedOx reaction 2KMnO4 + 3H2O2 > 2MnO2 + 2H2O + 3O2 +2 KOH. The decomposition in the other examples is also a chemical reaction 2H2O2 > 2H2O + O2. Now I am just a TA not a Studied Chemist but the coconut charcoal got me thinking how it would work with Active charcoal as it is used as a katalist in similar situations
It's a catalytic monopropellant thruster!
A little refinement and you'd have yourself a nice reaction control system solution!
C-stoff is not made of potassium permanganate, it was a mixture of several components consisting of (by weight) 57% methanol, 30% hydrazine hydrate, 12% water, and 1% potassium tetracyanocuprate, combined with high test hydrogen peroxide it created a hypergolic fuel which combusts at very high pressure and temperatures. Potassium permanganate mixed with H2O2 does not generate anywhere near enough heat and pressure to be used as a rocket fuel, and unless you inject fuel into the oxygen stream it will provide negligible thrust.
📷Video Idea: Would love to see you exploring how to make engines more efficient in terms of the ratio between consumption x thrust 🍅
isn't that endstage maximizing of thrust?
Awesome work and effort. great job
Excelente vídeo Joel!
Hi Integza! Im getting a 3d printer later today! Love you man keep making awesome shit!
Two engines that have always fascinated me are the RAM Jet and SCRAM Jet engines designed for extreme high speeds with little oxygen. Might be interesting to see a hybrid pulse detonation SCRAM Jet engine.
Or a hydrogen peroxide powered rotating Detonation engine 😉
@@luigidavid8554 I like the way you think 🤔, That sounds awesome.
Great video, try activating the coconut charcoal. If its acting as a catalyst, I'm certain activating it will give you a better effect.
hello and happy new years from new zealand!!! suggestion for fast evaporation just sit a fan on the top of open container blowing up and away from container but with enough room under fan to allow air convection current to draw from top of liquid.. takes a while but its cold no heat tho if slightly warmed will work faster..but at least you can leave in corner for a few days and won't cause any issues!
Hi integza! I think you are getting there! BUT, be careful with the H2O2 concentration. As you concentrate it, you need to keep a certain level of “stabilizers” in it. If not, it could spontaneously combust. That is why high concentration H2O2 is considered so dangerous. I suspect you already know this but just for everyone else, this stiuf can get nasty if you don’t know what you are doing with it. So be very careful and don’t do this in the house and make sure you know the chemistry properly (with the stabilizers) or you could get a nasty surprise from this stuff. And that assumes you do all the handling properly (everything ultra clean because just a dust spec can act as a catalyst to set it all off). Cool, and looking forward to the next version!
As an aid to visualising the results have a look at the damaged caused to the very heavy duty facilities built in WW2 by the Germans. Tino Struckmann shows the damage on his many documentaries on Lost Battlefields.
Now I'm wondering if activated charcoal is the best thing to adsorb the permanganate onto.
Also I'm assuming you must have stumbled onto it, but ExplosionsAndFire has a great video about concentrating hydrogen peroxide.
I came here to recommend the same video.
I would love to see a collab between tom and integza on this
Are you guys talking about the video where they freeze the h2o2 to concentrate it? I couldn't remember who was the person to do it that way...
@@Phred_PhlintstonerI honestly don't remember how the video went but that was my first thought to comment about that video
@@Phred_Phlintstoner kinda, he spent like 112 days or something to get it to 90ish percent before he froze it. Problem with freezing is that around 60% it forms something similar to an azeotrope in distillation. Fractional distillation under vaccuum is the way to go
and it only took three russian days
Hey integza! I love your nerdy engineering content! Keep it up!
The idea with the foam is really cool. Perhaps you should try to cut different patterns into it so that the surface area is bigger at ignition.
I used to make H202 rockets and distilled my own 90% peroxide using 50% food grade, a simple home built vacuum still and a halogen light bulb as a safe heat source. I could easily distill about 2 gallons of roughly 90% from 5 gallons of 50% in about a full day (you lose a lot with a crappy homebuilt still), but storing 90% peroxide is way more challenging than distilling it, stainless works, but 1060 aluminum containers are best.
Also, 99%+ pure silver screen works great as a catalyst with 90%+ H202, not so well for anything below 85%.
As always, Great video, and fun idea! I'm actually thinking about buying a 3d-printer this weekend so i'm looking forward to following in your footsteps. I also have a videoidea for you: Please team up with Peter sripol and make one of your rockets actually fly! You could mount it on a low speed plane, but I want to see if you could create and actually fly a jet-plane
Or make a challenge for other creators out of it on who can go highest in his rocket
just be careful lol dont get plastic shrapnel stuck all over urself
Use a block of Chalk (climbing/weightlifting chalk) instead of foam, it'll absorb an enormous amount of Potassium Permanganate.
I like your multilingual translations, it made it easier to understand
What an awesome concept! I’ve worked at spacex for 8.5 years, first as an engine technician, now as an analyst. I’ve worked hand in hand with test engineers for years and have been sharing your videos with some of them, specifically ones that have worked previously with 3d printed propellants
Idea for future video: make a thrust vectoring nozzle orrrr even cooler a rocket fueled with hydrogen ,also love your videos
I would love to see a hydrogen thruster ,i want to learn more about it and integza always explain things great
Right, "I see you struggling making an engine that is powerful enough... Why don't you make it more complicated?" 😉
@@SchwuuuuupA hybrid rocket blowing the output through a final chamber with mini CD ROM discs slightly spaced apart.
Look up the hybrid rocket engine in the SSC land speed record vehicle. Concentrated peroxide is injected into a catalyst and the byproducts (heat and oxygen) are used to burn, essentially, rubber to provide the thrust.
Wow! Love your videos Integza! I particularly love the little bits of history you add to every video.
A cool video idea would be to look into the so called "Thunderstorm Generator" which is supposed to improve the efficiency of internal combustion engines by up to 30%. Whether you can replicate that improved efficiency or debunk it I think it would be an awesome video as the "generator" works be pulling a vacuum to collapse air bubbles within the Generator and ionise the exhaust gases for reuse in the engine.
Have you looked at molecular sieve for concentrating the H2O2 or would it also cause it to decompose?
That is quite interesting.. ive seen NileRed used it alot.. And Yes i look it up and it works.. i donno to how much degree it will but it does works
It works on etanol so maybe works with h2o2 but wouldnt it easily reach 100%? I know that the molecular sieves i used in school did not burn so i think its save to do. ( i dont know how tight water is in h2o2, sorry multilingual problem if this does not make sense)
@@Hnkka it is a decomposition reaction not an oxidation reaction so the concerns are different. Molecular sieves work by having fissures in the surface sized so that the target contaminates adhere to them, in most cases it's water. Because the molecular size of H2O and H2O2 are so close it might not work, but the bigger issue is that the high surface area might also give reaction sites for the H2O2 to decompose. Activated charcoal works in a similar way to molecular sieves and in this video he used charcoal as a catalyst for decomposition of the H2O2. I am unsure if the reason charcoal works as a catalyst is because of it's surface area or because of it's carbon content.
thank you for making me smarter@@Zanthum
If you use 3Å molecular sieves it might work. That extra oxygen increases the size of the molecule significantly. Water molecules are just barely small enough to fit into to pores of 3Å MS, so hydrogen peroxide molecules absolutely wouldn’t fit. However, the sieves are made of a type of clay called zeolites. Zeolites contain metals, and metals cause the peroxide to decompose. The only why to know for sure is to try it. The sieves naturally bubble a little when absorbing stuff because air is displaced, but if the peroxide is decomposing a lot of oxygen will be released.
I'd like to see you make a self-propelling charcoal turbojet engine!!
now this is real backyard science love it, verry educational :)
Okay I can't help but imagine using a flash cotton instead of the flowering foam... That's would be interesting
we want a rocket, not a bomb.
You are a genius i think you should try on building iron man suit

Hi
Manganese dioxide also works with peroxide very well. Cheaper than permanganate, and you can mix it into stuff and bake it or even sinter it to make a ceramic composite. Some rocket packs use it instead of the fancy sintered silver catalysts.
Like if you think tomato's are disgusting
Tomatoes are delicious.
Wow, great motor! ❤
@Integza You can try it with the frosting method try to put your peroxid and water solution in a freezer with min. -18°C and let it freeze slowly so the water doesent captute the peroxid after that try to decant the peroxider off the water and repat this process a few more times. Sute this might take a bit longer but with enough Patience its doable or you can use dry ice to speed things up
Connect a dehumidifier to a standalone freezer. As the air inside the freezer dries, it will become very thirsty. Dry air at any fregid temperature lower than the room temp peroxide solution (on a stir plate) will quickly suck nearly all the water out.
the reaction between peroxide and Permanginate is a chemical reaction forming O2 and MnO2 that catalyses further peroxide decomposition. Decomposition is just the kind of chemical reaction it is.
This seems like it would work really good in space as a propellant for small crafts maneuvering.
An interesting thing to look at with this might be some of the old British rocket programmes - IIRC the Black Arrow launch vehicle used RP1 and HTP (highly concentrated hydrogen peroxide) for a clean, if somewhat heavy rocket engine. Perhaps there might be a way to mix the HTP monopropellant effect to prime and ignite a bi-propellant reaction?
they make drying pelets you can add that draws the water out and will give you a purer result and faster as well nile red uses it all the time to pull water out you might try them
Integza
If you put the charcoal in a pressurised steam cooker you get activated charcoal. Cody's lab has a video on it.
You could combine the spinning laminar flow technique from your other video to add more peroxode. Spin the chamber on barrings !!!!!!!
Integza: "I want to make a V2 Rocket"
London: [Breathing Nervously]
We should try using MnO2 to speed up the reaction if it's less expensive or try increasing the surface area of the foam through porous spaces to increase it even more
Take the water out with molecular sieves, they're faily cheap and can be reused a lot. They're also good for making anhydrous ethanol which is fun
Great video!
I have suggestions for your next things to try. Musing more than anything else, but one extra step to the flower block
A material that has these properties is exactly what you need.
It transmits heat to clinging water so well it can boil ice water with sunlight.
I understand this material has more surface area than the famed coconut husk carbon.
Pyrolize it. Then heat it under pressure at 300C with nitric acid and iodine for 6 hours. Cool, open. Heat to 90C to drive off the nitric acid.
My geeky brain thinks this should be perfect.
Great Build idea. Safe steam generator for use with projects like the Tesla Turbine. See, I told you, it’s a great idea.
Use magnesium perchlorate and a vacuum desiccator to concentrate your peroxide
To improve the efficiency of the engine, you could create instead of the showerhead/brass tube design, use a series of impinging injectors, it would be really easy to manufacture such an injector plate with 3D printing. For the KMno4, maybe look into seeing if it could be mixed with aerogel, it's lightweight, has an incredible amount of surface area and would make a great video, even if it might not work.
Look into investment casting for wax. Then take those techniques and replace the investment plaster with your permangenate plaster and create negative of the desired combustion chamber (less walls) out of wax. Then pour your permangenate plaster around the wax and burn off the wax so you now have a more ideal combustion chamber with higher contact surface area.
Also maybe inject the OH into the chamber at varying points in the chamber and have feedback loop comping from the chamber to apply pressure to the OH reservoir so the motor can drive itself.
Good job making large leaps in catalyst design. I was wondering if crushing your ceramic soaked in the KMnO4 would work well too. Although it wouldn't be as light as the foam
I'd suggest you could try to enhance the water vaporization by lowering the pressure. You could build a vacuum chamber out of thick plexiglass & use off-the-shelf vacuum pump to create vacuum. You could then make a tiny hole for a power cable for the hot plate which would be put inside. Make sure that you seal that hole with cable as much as possible to avoid leaks. Or you could use some sort of induction coil to transfer the required power wirelessly. I think ElectroBOOM could help you with that.
I think you could use a vacuum chamber to make evaporating the water out of the peroxide easier.
Have you tried a version of freeze drying for your h2o2 concentration process? Run cooled, dry air over the top of your container while maintaining moderate to low heat in the liquid. That should speed the process.
I’ve signed up for Nebula because of those two channels you listed. 😁 I’m super glad that you are joining Nebula as well.
Cool video, the H2O2 at 50% scares me ! But actually the more concentreted H2O2 is the more stable it is, at room temp, so keep going higher !
Regarding the burning of the wool, it is logical, KMno4 is a very good oxydizer, it can even triggers thermites when mixed with some glycerine.
A very good catalyst is MnO2, you could sinter small particule in your oven to get a high surface area and a solid.
Have you considered a molecular sieve for getting rid of the water? They're pretty cheap, reusable and can even be used to bring ethanol above the normal distillation limit.
Integza!! Look into membrane distillation!! You can move water with just a temperature differential, so for example make the input side of the membrane distillation tank at say 40 or 50 C and the out side at 20 or 30 C (bigger difference is better) and you will get water moving across the barrier. Contact me if you want my little bit of knowledge on it, or if you want me to put you in contact with my professors from college who actually were researching it. It works by hydrophobic membranes basically causing the water to evaporate on one side of the membrane and travel along the heat gradient to then condense on the other side.
Great video, as always! Perhaps a suitable way of evaporating the water would be to use a partial vacuum. It lowers the boiling point of water to a lower temperature, even room temperature if the vacuum is strong enough. I''m unsure what it does to the hydrogen peroxide, but I think it's definitely worth investigating.
I was bummed when you stopped working with the ion thruster. I get it though that other guy is a tool. Keep it rolling and I think you're on to something good here as well.
Little tip if you want to conentrate even more your H2O2, you can use 2 erlenmeyers linked together with tube on the top (so the air communicate but not the liquid), one filled with your H2O2 to be concentrated, and the other one filled with liquid dessicant (like calcium chloride, very easy to find) and only heating the H2O2. This will fasten the process and also take out even more water of the hydrogen peroxide
This needs more likes. Far better than the people suggesting vacuum detona- I mean distillation!
I think you should try different style of cartridge starters. Some planes and tractors used a shotgun cartridge but there’s a video on RUclips being started with what seems like a mini rocket motor cartridge of some sort.
