I've never feared for you life more than the moments i watched you hold a knife with a supersonic gas output with a flame front that was traveling back to the source.
IKR! on the other hand, the source's were neither explosive on their own, only the gas in the tube "downwind" of the point they mix could have exploded.
@@ristekostadinov2820 oh yeah, but electroboom tends to electrocute himself on a hourly basis and I can't remember the last time styropyro got hurt. Would love to see an actual competition tho 😂
Hydrogen burns at 2000 degrees, as the camera pans towards the ceiling, I was totally expecting the next shot to be the fire department showing up. Instead it's him adding oxygen to make it burn even hotter. I don't understand how he didn't burn down his home.
A sword version of this with only half of the blade burning would be a terrifying weapon. Keeping the fire a half a meter or a foot and a half away would be a big improvement for the user too.
It would look pretty sick, but it would also become unusable after 1 light hit. This stuff isnt really strong, nor would actually cut as there is no real edge and meat isn't bread. Also, because of the heat the metal would become even weaker as soon as you turn it on :/ still though..
@IWontBuy-RP thats why you use it for self defense. who in their right mind would try to rob you after your mostly normal looking sword catches fire. or starts glowing red-hot from an invisible flame.
Tbh i would have liked to see more of the hydrogen with compressed air and experimenting with that cuz invisible fire making a red hot knife is COOL. cool video otherwise also keep in mind that Tomatoes are disgusting!
@@cult-of-sporque Yeah, without a flame/flash-back arrestor or two separate fuel/oxidizer inputs, that is a detonation waiting to happen. Source: I'm a welder.
This concept has been in use in high-performance (military) jet engines for more than a decade. They don't use it for fuel injection, but rather air cooling the rear turbine blades. Turbojet power density increases with combustion chamber temperature, but past a certain point no existing materials can withstand the heat. The solution was to bypass some of the air from the compressor section through tiny holes in the rear turbine blades to cool them well below their melting points, minimizing turbine blade creep.
I was a tooling design Engineer for a company called Amchem that developed the process to machine holes into the internal galleries of Rolls Royce turbine blades and stators. We used an EDM process with tiny hollow brass tubes in the tool heads, it was a great job.
The fact that the man casually says "this burns at 2000c" while doing it inside and probably blistering the living hell out of his ceiling paint is crazy.
Okay but this is literally exactly what cheese wheels need to be melted with, this is literally the best, most effective, and coolest cheeser i have ever seen
na, hackensmith already bought that franchise and are running with it, he might get sued for copying them lol could be cool to see a fully Two handed sword on fire tho, blue fire like if Belgarion, the god slayer was using it, lol
I like the idea that you went, "not a fan of this plastic spinning next to me. I think ill stop." But you were just playing with hydrogen and oxygen in a shared line. As someone whose accidentaly caused a small explosion in that same way, that made me fucking nervous.
Same, every few minutes I got crazy nervous and mad at him BC he never said don't try this yourself and that stuff was dangerous af. He literally put a highly flammable battery that could explode or catch fire (which would not be easy to put out) when subjected to heat next to a handle that is so hot it burns you through gloves. And that is only one thing.
he hooked up air not pure oxygen. still really dangerous but a pure oxygen supply is the one where you need to build flame arrestors in the line or else itslikely for your supply to explode.
It would be awesome to see a 3D-printed old-school cannon that shoots cherry tomatoes 🍅 or 3d printed projectiles using the rocket propellants you previously created. I'm also curious if you could add rifling in the barrel and show the difference between with or without it. Would it be too hard to make it with a 3D printer? Missing some explosions lately ❤
That is so cool! I tried making a flaming sword once by casting aluminum over a tube that ran down the length of the tube, then drilling through the edges of the blade. It was a bad design.. for a lot of reasons haha. That works so much better and you can still use it like a knife!
I would love to make a sword using the porous metal but is hard to fit a sword into the printer volume, I’m looking into making porous metal without using 3D printing !
Hey guys ik you guys probably won't see this comment but I do have idean of making a porous sword by mixing matel and I would love to work with yous guys I recommend watching the video on yt of making pink gold I will put the link of the video and you can use Raney Nickel is typically made by treating a nickel-aluminum alloy with a strong alkali solution, such as sodium hydroxide (NaOH), to remove the aluminum. This leaves behind a porous, high-surface-area structure of nickel, which is then often activated by further treatments like heating in hydrogen gas. The resulting Raney Nickel catalyst has enhanced reactivity due to its increased surface area and porosity. Idk if this will be structurally strong or not but you can give it a try the video link in of pink gold which had pores or cracks :ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-d6Pcp944sRI.htmlsi=se7V1MFxZNtVxKOp
You're thinking too small. You MAY be able to create not just a normal jet engine but a DETONATION engine. The trouble with detonation engines as I understand it is the combustion mixture comes into contact with a hot surface or hot gas and ignites before the detonation flamefront reaches it. This technology might be able to provide a forcefield of constantly incoming cold (and yet unmixed) gas that prevents this contact from happening. Just like bread dough sticking to a knife.
a cylinder made out of this metal, that pumps oxygen through itself. Inside that cylinder, a second, smaller cylinder that pumps hydrogen through itself. That way it wont have the same issue the knife had with heating up when the gasses mix. This should allow for that gas mix to happen outside the metal... maybe a good idea. I'd say worth a test.
I don't get a chance to mess with aero engines too often, but I do work rather frequently with large gas turbine fuel systems at my engineering job. They've been using diffuser-type reverse flow fuel delivery systems for a while now with pretty interesting results! I highly recommend that you look up the General Electric DLN 1.0 combustor system sometime, Integza. Its an older design from the 80s but in terms of flame stability in high-flow combustion its really quite impressive, and being older a lot of the documentation is freely available online.
Okay so the coolest part to ME was that it "Self-Cools". Air is a super good Insulator, that's why Insulation is often just very very porous materials or Fiber's of something. So, when the knife is burning something without an oxidizer, it would probably never get hot enough to damage itself. BUT when you add a little more "Power" with the oxidizer, it get's Red-Hot and the SECOND the oxidizer is gone, it self-cools and stops glowing. To me, that is incredibly cool!
now make the next step, jet engines suffer from cooling issues and potentially can melt themselves make the heated componants (post combustion camber compressor blades etc out of that material and you overcome the cooling issue which allows for hotter more powerful engines.
It still needs better cooling though, getting red hot is probably closing many of the holes permanently. It needs interior pathways that can individually be enabled/disabled to manage heat. What would even better is a design that automatically limits areas based on material expansion as those areas get hot, maybe have the interior of the knife also designed as a heatspreader via material usage.
Is it a bad thing that I was on the edge of my seat watching you eat an entire dinner meal on camera? haha. I see the potential this tech has, and fully expect you to expand upon this.
@@loganiushere It isn't the only reason. It's state-sponsored so the slave labor isn't the only reason they're able to undercut all competition while filling up landfills with poorly made products. It's backed by the state as a method of economic/social influence.
I learned about this metal in the exact same way you did which is hilarious😂 And the fact that we both came to the conclusion that we had to make a knife out of it is hysterical😂😂😂
Or you could actually Make a lightsaber using this principle with a telescoping tube, this could either become a bomb in your hands or evenly distribute the o2/h2 mix within the space and allow the pores to act as a filter screen so long as you have a double barrier between the ignition area and the fuel injectors (for safety, if you care about that).
Another material that looks just like the 3d printed porous knife, is the air mufflers/diffusers on industrial pneumatics. Under magnification, some of them look like brass beads that have been heated and pressed into a truncated (blunted) cone shape. If Integza wants an off-the-shelf porous material, that has pipe thread already attached, I would use the pneumatic muffler method. I just checked the industrial supplier McMaster-Carr here in the USA, and I see they even make stainless ones.
How to make ion jet thruster..? Idea is to make a jet engine combined with a ionic thruster to suck air. Thruster will suck air into combustion chamber and in combustion chamber it mixes with fuel and burn to produce high velocity gases and boommm this idea may work...
@@alext8828 I'm not sure, but I think it's typical leftist complaining, they contribute to so called "global warming", or they not "diverse" enough, or something along those lines
I was thinking that I would love to see a fan driven, Nitromethane liquid rocket engine. With an aerospike nozzle, so it looks like the blackbird's engine. Great video.
Apparently, Russia uses jets for snow and ice removal. I bit excessive though, as I would think it would exacerbate asphalt degradation... If not from the heat, then from the plain water being able to seep into cracks and freeze, making said cracks even worse. Anyways, for leaf removal... As long as you don't do it anywhere on Earth, it'll be fine! lol Otherwise, you'll just be burning down every forest you use it near, *_and_* the homes in and around it. 🥴
this is a recipie for brownies: 1 cup (225g) unsalted butter 2 cups (400g) granulated sugar 4 large eggs 1 teaspoon vanilla extract 1 cup (120g) all-purpose flour 3/4 cup (90g) unsweetened cocoa powder 1/2 teaspoon baking powder 1/2 teaspoon salt 1 cup (175g) chocolate chips or chunks (optional) 1 cup (120g) chopped nuts (optional) Instructions: Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking pan or line it with parchment paper. In a medium saucepan, melt the butter over low heat. Once melted, remove from heat and stir in the sugar until well combined. Let it cool slightly. In a large mixing bowl, beat the eggs and vanilla extract together. Gradually add the butter-sugar mixture to the eggs, stirring until smooth. In another bowl, sift together the flour, cocoa powder, baking powder, and salt. Gradually add this dry mixture to the wet mixture, stirring until well combined. If desired, fold in the chocolate chips or chunks and chopped nuts. Pour the batter into the prepared baking pan and spread it evenly with a spatula. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). Be careful not to overbake, as brownies should be fudgy. Allow the brownies to cool completely in the pan on a wire rack before cutting into squares and serving. Enjoy your delicious homemade brownies!
@@sethreign8103crush it up in your mortar and pestle (the one that comes free with your xbox) and dump it in with your dry ingredients. or mix it in with the topping.
I thought the same thing except for the back of a single edge sword so that the whole blade trails fire during a swing. In slow motion it should look epic.
@@logitech4873 It saves your payment info and adress without your persmission and then either sells it or chrges you additional costs without you knowing later.
I swear, your channel is a near constant barrage of super interesting forays into jet engines but this video was completely novel and exciting. Thank you for showing us this kind of stuff (and I'm happy for you that you get to do this, too)
You nearly unsubscribed to a RU-vid channel that provides you with entertainment free of charge because of his choice of sponsor? How dramatic! A little egotistical, but how dramatic!
you should try to make a pulse jet engine out of the porous metal, you could seal the outside of the metal body to make sure all the gas only going inside the engine, this would allow for even spread of the fuel throughout the engine and possibly make new and very efficient engine. (from there you should put it on a rocket and launch it up to see what happens)
@@nic.h not that much as most engine (rockets) are just nozzles and bells. you'd still need to pipe the fuel to the combustion location. (blade of the knife). i am interested in see how he will implement this into an engine. my initial thought was using it as a oxidizer or fuel injector. the problem is the lack of control and consistency. he mention that the tip of the blade is hottest and we saw the spine had much more fuel leaking compared to the blade as well as uneven heating. Now i don't know if the 3d printing process can control the flow rate of the blade (or other shapes) by making the porosity consistent
Might be possible to do so with metals that are very resistant to high temperatures. But then there's the other problem, they're very resistant to high temperatures, therefore, very hard to manufacture
Kawasaki did it years ago on one of their JetSkis. High pressure air was injected through ports on the front of the bottom of the hull. I can't remember what model, they didn't do it very long since it was prone to issues. But other ships have done it as well. Air Lubrication Systems they are called.
@@coffeegonewrong Why would the upper/interior parts be porous? That would be a foolish design that wastes half the power and whatever gas is injected into the hull. If only one side (or only the blade...) of the knife needed to have the desired properties, they would seal the other parts, as they did with the handle of the demo knife and support fittings of the industrial ones. Also, there's a point in hole diameter where air and other gasses can pass, but liquid water will be stopped. That's what Gore-Tex material does.
@@VoltisArtI didn’t know that about goretex. Sorry, sealing the parts you don’t want leaking makes more sense. I guess the mental image was funny so I wanted to share.
I'd love to see a video that explores other unconventional uses of 3D printing, and the potential they hold! So cool that all this came from a hiccup in the printing process!
Video idea: Make a metal 3D printed jet engine with regenerative cooling. You can print the combustion chamber and make the walls hollow for the fuel to go through. It will keep the chamber cool and heat up the fuel (wall | hollow space | wall | combustion chamber | wall | hollow space | wall)
A sword like this, but made from a much stronger material, or coated with something like boron carbide while maintaining the porosity. Add a water chamber to the handle, and add a battery and circuit to generate H+O2 from the water, or even Brown's Gas (HHO), which might be better because of it's weird nature. Then use that HHO or Hydrogen mixed with Oxygen to light the blade, using an electric spark activated by a switch or button. Then the whole thing is self-contained. Oh please make one, and then make a bunch more and sell me one cheap. 😉
I kinda wanna see you make a Warhammer 40k Melta gun. Which is described as a compact jet engine (rifle size) that is used for melting through naval ship doors and even tank armor in short ranges.
A rocket engine would be better. Have two tubes, each containing liquid rocket propellants, and have them mix in a combustion chamber with a very tiny nozzle. Recoil would be bonkers, but it would absolutely fry anything it touches.
I mean, he'd already beat _that_ standard earlier in this same video. The flame was likely traveling it's way back _through_ the knife while the gas flow was mixed...
I just rewatched the 2005 movie The Hitchhiker's Guide to the Galaxy, so it was fun to see this rather more flamey version of the knife that toasts as it cuts.
Driving the shaft of a Stirling engine causes the cold part to get really cold. Maybe driving one with wind could be used to condense water from the air. You should try that.
for your next jet engine, you could use this porous 3d printing to run air to hotter components such as the turbine to cool it as it gets very hot and sometimes can melt
I suspect that being able to seal the spinning turbine whilst also having it ported to allow liquid to flow through it, would be an absolute nightmare! Also, the fact that the centrifugal forces would caused the coolant to coalesce at the tips, would be problematic. I believe some of the blades are already hollow, to be light weight, and that adding liquid would undo that aim of being light (so that they can spin fast). I feel like if them being cooled was that necessary, they would've already leveraged it being hollow, to pump coolant through. (not trying to crap on your idea, just playing devils advocate; I commend you on your outside the box thinking! 👍)
One of your most satisfying videos! The quote "Am I missing am eyebrow?" from Adam Savage of Mythbusters ran through my head the whole time while watching :) Although I feel the Adam Savage "Am I missing
I am trying to make a jet engine powered skootey I am kinda new to this format but after writing your videos i am damn sure i will succeed in just a year thanks man
