You need to visit Huntsville

I big thank you to Dr. Myles, Dr. Eric Bach and Dr. Quentin Michalski for the help they provided!

Operator: "It has previously blown the door off!" integza: "Prove it while I stand behind a potentially high velocity projectile that could squash or seriously maime me!" Crazy man! lmao

This dude’s just moving up the tech tree real fast

Just when I thought there were only so many types of rocket engines, my mind gets obliterated....tomato level obliterated. Phenomenal Joel!

My favorite engine you've done so far!

"If I had a nickel for every time I heard of an engine that starts another engine, I'd have 2 nickels, which isn't a lot, but it's weird that it happened twice."

Joel: "Smaller is safer, right?" Also Joel probably: "Surely splitting apart an atom is safer than splitting an apple..." 😂

Suggestion: Journey to an actual standalone rocket/plane/car - I really enjoy your content but working towards a practical, containerised engine for moving vehicles would propel you to anti-tomato legend status! I know it would be a much longer project, especially getting pressurised fuel into a reliable lightweight stand-alone format, but maybe collaborating with more like-minded people from e. g. the RC sector could make it a lot easier - In any case I look forward to seeing what comes next!

I love your videos!, create a drone powered by a rocket engine!

with each passing video from this guy, I am closer to burning my house down by trying it at home

That slow motion video is freaking awesome

Fly to Mars using a 3d printed engine. Edit-tomatoes are disgusting.

Integza, you are incredible, this engine has been used solely by research labs. Amazing work.

Good to see those safety glasses protecting your forehead. Very important, especially while peeking around the wall at the tube potentially filled with H2-O2 mixture.

Modern shells have smokeless powder which is different from blackpowder which is what was the original gunpowder.

I just still watching Integza just to be sure that I won't miss when he blow his room away.....

Damn Bro I still remember you working out of your fire hazard of an attic with just a 3d printer and limited knowledge, you have come so far in a impressively short time! Its very inspirational honestly! keep it up man!

How that tiny engine made that metal rod glow and bend is insane. Imagine this little engine being 100x the size.

Sounds like a Pokémon entering into battle

After following integza for quit a while it's makes me happy to see how he started from making working stuff that looks like a grandma who's waiting it's final moment to be free to Making thing that actually works and looks like it was made to last, very proud of you integza😢

After following Integza for a while, I think the real question is: when is he flying to the Mars using his 3d-printed engine?

For a second i thought you were going to attach the jet to the RC car...

Expert: don’t do that you will kill you self. Integza: here are some plans. Build this and tell me what you think

Make a solid rocket engine and attach it to a cheap RC car or drone!

Maybe you could 3D Print a Ionic Thruster? If it doesent work just increase the voltage and make a Tomato Roaster out of it *evil laugh*

Damn it doesn't look much until you hide behind the cover that's INSANE

An episode on Teslas tower and building one …maybe?

I’m a researcher at the University of Central Florida specialized in RDE’s and Pressure Gained Devices. I have been watching your videos for a while and would love to talk more if you are interested. My next video idea would be to make the RDE combustion chamber annual and attempt to observe the actual rotating detonation. An additional idea would be to create a planar RDE which would use this exact same set up and would just be used to observe the detonation wave.

Idea: I would love to see you use a piezo pressure sensor with an oscilloscope and a high speed camera so we can see whats really going on and maybe improve the engine. ( i know high speed cameras are very expensive but maybe you can lend one locally or from Dave of eevblog)

my guy was told there was enough force to punch him into the next room and wanted to stand next to it

You should try making a rotational detonation engine powered remote control car or boat once you figure out getting the engine to run with a rotational wave for an extended length of time.

As an alternative to the primer from gun shells, you could go to a well stocked tool store and ask for the "powder loads" or "strip" for a Hilti gun (aka "Powder-Actuated Fastening Tool"). The nice thing is that those come in multiple strengths, so you can pick one that works for you.

Video idea: Build an Ion drive propulsion engine! It can be quite simple, MIT made one that’s pretty much just a positively charged cable parallel to a negative, they made it generate thrust, so Basically it’s a glorified air purifier with a cable behind it. There are some other more complex concepts like the ones they use on spacecraft (every SpaceX star-link satellite has one), although they are more complicated and expensive.

This is something straight out of science fiction, like some alien spaceship thruster

Maybe you need to add an aerospike so the detonation has something to spin around. The Miles-Bach-Michalski engine has a central spike though it was truncated. Another thought is to move the primer to the back of the device instead of the exit port and angle it to induce rotation. The MBM engine had their starter in that position. Also being in the Northern hemisphere you will want to spin anti-clockwise so you aren't fighting the Coriolis Effect.

You are really crazy! Please keep going! :))

My theme suggestion is to create a load cell to compare the different engines you've made so far. Seeing these home-made 3D printed engines is great. But giving people context like how much force this engine is producing, and maybe how much fuel its using compared to other engines you've made, might be even better.

"A little rocket that flies around the corner and lands on its belly" Eli, 4

I'd like to see you build a rudimentary rail gun with the projectile being a hammer head and launch it at a door? Maybe you could feed it into the rail gun with compressed air.

Man these videos are getting so good. Buddy went from homemade carbon fiber pulse jets to visiting national labs and working on cutting-edge stuff in the space of a year, all while managing to educate his audience. Well done.

Integza, with his moustache, shaved off all of his limitations

Suggestion: I realize you covered the concept years ago in a video, but it would be great to see you actually build a sonoluminescence experiment yourself.

Erased is my favorite anime of all time. It will absolutely destroy your feels and will make a grown man cry. So good though

The gas engine looks cool but let's return to the piston engine. Have you ever heard of "The Stirling Engine"? Mostly, the engine uses little heat to run and spin quickly.

It's so cool to see how every video his design gets better, materials get better, and his success rate improves.

Don't do this at home (but anyway, I left the 3d printing files in the description

The primer is made from Mercury fulmenate. Just in case you were wanting to know...

This guy is insane, that's some amazing high speed footage too Also, using a smaller engine to start a larger engine is not terribly uncommon. They're called a pony engine usually, and a lot of industrial engines and tractors have them.

The part with you standing up against the door when it went off reminds me of when I used to work for my local utility. One day I was at the plant while they were doing an inspection of one of the gas turbines. I didn’t have much to do that day so I stuck around and watched. They finished up and went inside to spin it up for peak and I was just watching from the corner when one of them turns to me and says, “you’re in the no no square” Apparently, once the generator has synced up its voltage and phase to the grid, a massive breaker trips to connect the generator to the grid. If that connection fails for some reason there’s the possibility that all the power that generator is making will explode out, ripping the massive steel breaker door off its hinges and sending it straight through the no no square and whoever happens to be standing in it.

We were advised against subjecting skin to high velocity air. Apparently it's unsafe.

Here’s an idea for the next show. How about creating a small vessel, utilizing the engine on this show to provide enough thrust to exit our atmosphere. Just a simple experiment to produce the necessary thrust required to successfully exit earth’s atmosphere reliably, and repeatedly.

The level of your videos are improving everytime, not only in design and performance, also in post production, clips etc.

This is so awesome. Pretty insane that we get 5 min of incredible footage that probably took months to plan and bring together

Please build a Turbo Encabulator

You a couple of years ago: I want to build a decent chemical rocket motor. You, sometime next week or so: My warp engine is running too hot.

This hands down is your best project yet, and that is saying something since your other have been better that the last for nearly a year straight now! thank you for this channel! keep it up!

I think you should make a tip jet helicopter with one of your rockets.

Get yourself a full hardhat with faceshield instead of just goggles. The faceshield will protect your neck.

3d printing titanium must be difficult.

It's quite impressive how you're able to make these projects, especially since this is cutting edge technology that governments, corporations, and universities are researching. Truly outstanding work!

Damn dude I can’t wait to see the engines you’re making in 3 years. Every video you improve your building technique and they work better and better

Just like they lost that laptop then wonder why the ISS gets shut down from a remote source they've never been able to track.

68.2% insoluble nitrocellulose, 29.8% soluble nitrocellulose gelatinized with ether and 2% paraffin. To make your own smokeless gunpowder next time

Idea as part of the next video: a proper (transparent) blast shield! With the explosive nature of projects on this channel it could come in handy!

Two ideas for future videos: use one of your amazing engines to power an RC car, or do a comparison video, comparing some of your engines based on thrust, fuel consumption etc.

How about a rotating nuclear detonation engine? That would be super neat!

The scream is the rolling detonation, the frequency of the scream is the frequency of the rotation

A very neat test! I don't think you got to actually make a rotating PDE - but that is a descent attempt. I would love to see either form of 3D printed PDE actually taking off up in the air. It probably will have to be a theathered flight test... But I am doing more than just asking - community effort, right? - I'm also offering - I am more than willing to machine parts for the project too!

You know if you build a simple wire EDM lathe you can make parts with tungsten, and I hear that handles heat pretty well

You could make a drone that flies using steam or some form of combustion, It’d be a fun challenge and watch if you got it working!

Thank you Joel! If you’re interested in investigating a hitherto unexploited means of generating commercially viable electrical power from oceans or lakes - not waves, not tides, not currents - please get in touch. It might change your life 😉

I kind of want to see more from this RDE guy. Super interesting subject and he's very engaging! Also that setup is absolutely rad!

I swear every video gets me more excited to see what the next one is. the rocket engine experiments are so cool the way you do them

Maybe you can build a real Launchable Rocket with the F1 engine.That would be awesome.

Thank for your work ❤

You can make a suitably sensitive primer type powder using Armstrong mixture from matches. The gun powder you used is actually smokeless powder, it’s nitro based and burns slowly at stp but burns much faster under pressure. Black powder (the old sulfur and charcoal stuff) burns faster at STP but doesn’t increase burn rate with greater pressure.

Proud of how far you came and how hard you work Simply amazing

bro is sulking they wouldn't let him flatten himself with a pressure wave...and even they were giving a slightly peeved look that the lawyers and HR are like "yeah no...be happy we let you stay in the same building...lol"

Amazing video, love the exitment you show for every single project, can't wait to see more from this one

I like how much he never lets anything get him down, he keeps saying n trying.. it’s great!

Lead styphnate! That's what the primer's explosive compound is. It's encased in the copper that you're heating.

When you get the engine working toally, just maybe do a Rocket video on it!

Can’t wait to see a tomato vs the next RDE 😈.. impressive project btw! 👏😎

You’re a massive inspiration. You make high level research accessible and understandable. Part of me wishes I was still in physics.

colaborate with that LASER guy!!!

This is a super cool vid! I wonder how our world would be so much better if forgotten and discarded tech and ideas had never been discarded and forgotten.

Thanks so much for this video. It's been my ambition to build a tiny RDE for a while now, and now I have a few critical questions answered and new resources I hadn't unearthed yet. Keep up the amazing work!!

Wow.!!! Now including interviews with scientists and engineers, shows how genuine your work is. Your humour is what makes your channel, pure class. I look forward to every post you do.

We used to put shotgun primers in a vice and smack them with hammers when we were teenagers in the mid 90's!🤣

man went full anime for about 30 seconds

Did…did you just build a rocket motor that…actually worked?? As someone who’s been following your progress for a few years (or at least it feels like it) I am very happy and proud to see this

I love watching the evolution of your content from your first engine tests, keep it up and the quality keeps getting better!

I suggest one that burns salt water by oxidation.

Build an ion thruster.

RDEs are typically an annular design with a center spike (similar to aerospike), so you could potentially try using a cooled center spike to guide the rotating detonation wace around the circumference Edit: In addition, the detonation wave propagates around at the inlet of the chamber so your ignition source/detonation seed should also be closer in that area

Thank you - the external experimental scientific input was a great idea! You are really working hard to deliver knowledge on a very easy an comprehensiv way! Thanks!

I like your way to explain every thing

You just know these guys have at one time or another used this as a pickup line. "Hey babe. I'm a thrust-scientist."

You should have a build series of some kind of aircraft with one of these engines and then test it out I would totally watch the whole thing, keep up the awesome engine videos I think we all enjoy learning about them!!!!!
