Integza, BetterHelp is not the kind of company that you want to support. They've leaked private customer data in complete flagrant violation of any and all privacy laws, and their "therapists" are horrible.
Integza, my sibling in Tesla, don't mess with homemade pressure vessels. Use an old LP gas tank or something similar that is designed to handle the pressure.
Super vidéo 👍👍👍👍👍👍👍👍

You said that you wanted more mass on the turbine wheel so that it has more ”hmph”, but the thing is, inertia does not increase torque or power. It only smooths it out. This is a very common misconception regarding flywheel physics. Very cool video though!
Maybe you could build your own combustion engine.
Why don't you attach the system to a gokart? And maybe have both front wheels connected to gear. The one wheel will make the board turn :P
double the thrill!
imagine the chaos if we went full throttle
Attach it to a gokart?
😂😂😂
Attach it to a go-kart? Sure, if we want to make the next Fast and Furious movie, Rocket Skateboard Edition!
*I propose to make an electric turbojet engine. The point is this: we place a spiral, for example, made of nichrome, into the combustion chamber. We apply voltage to it so that it becomes hot, the air heats up and expands, just like in a conventional turbojet engine. According to approximate theoretical calculations, in the engines of passenger aircraft the ratio of the mass of air to the mass of kerosene ejected to create a jet stream is 50 to 1, i.e. in theory we will lose no more than 2% of thrust for the same energy consumption*
It will be a fun experiement. Of course the harder part is generating the electricity as efficiently or carrying it with heavy batteries. This was sort of how the US made their nuclear powered jet engines. I doubt that carrying an engine to make electricity is as efficient as just using an engine.
@@ivy7642 Well, we will also use air expansion, and regarding batteries, we can use lipo batteries for the experiment, they can deliver a large specific current relative to their mass
I've thought extensively about this and I think the only practical way to generate enough thermal energy without blowing out your heating element is instead to use an arc, similar to an arc furnace. The amount of thermal energy contained in kerosene is really hard to replicate with electricity at a practical level.
@@jamesburleson1916 I also thought about the spiral burning out, an interesting option would be to wind it around a tube and let air pass inside so that it does not collapse, but then what should the tube be made from..
@@PolcovnikGauss Honeycomb ceramic. Won't melt, just needs a good geometry for airflow.
Precious advice : never stay in the plan of rotation of something that's heavy and spinning fast. In aeronautics, we learn quickly to avoid staying next to propellers and turbines (see those red lines on the sides of the fuselages, right next to the turbines or propellers ? It's here to tell you that if it breaks, the spinning compressor discs will cut everything at this place) ^^
Close! Specifically, it’s to warn ground personnel that this is an engine ingestion zone and to stay clear when the turbines are spinning.
When welding the cups together I already though "ah, now he is building a bomb"
But when he stepped onto the skateboard I saw that the dangerous flywheel path was now conveniently shielded by the 200 bar N tank, providing some additional "safety"
Not sure which one is the better bomb, if something goes wrong 😂
Was thinking that too when he was spooling that. The energy that's held in high speed rotation is insane. We had a kid a school almost loose his fingers spooling a ball bearing with compressed air. It exceeded it's ability to spin and seized with his fingers wedged into the inner race. Thousands of rpms to 0 in a split second. He learned something that day
welded two metal cups together and blowed it up to 8-9 bars... i admire your courage sir!
You mean craziness.
Holy crap. I was going to say to never stand in line with a turbine at spin up because that is usually when they have a catastrophic failure but that is not as bad as pressurizing an untested homemade pressure vessel. I am glad nothing went wrong but how have you lasted this long doing crazy stuff like that?
My thoughts too, absolute madness. The pressure vessel was filled with liquid nitrogen which would be like instant frostbite on anything it splashes.
Yep, squeaky bum time on both counts 🫣
And them he rides it between his legs! The balls on this guy..... well, I'll see when I'm done the video if they're still there! 😂
This was wild. My engineer nerves were complaining throughout the video („why don’t you ever do such crazy things? See, nothing happened!“)
Will send it to the safety guy at work to give him a headache. ;)
The fact that the turbine is a flywheel makes it even worse
Out of every video you've made this might be the one I'm most impressed you survived. Like holy shit, heating a homemade cryogenic pressure vessel without even having a relief valve seems absolutely insane. It's like the definition of a pipe bomb.
Standing in the line of fire for such a massive turbine and such high rpm doesn't seem particularly safe either.
With that said it was a very entertaining video if terrifying, just please give some more thought to safety before you can't.
yeah I was screaming at the screen WHY DID YOU DIY THAT WHEN A CAMPING PROPANE TANKS EXIST!?
I’m only 5 minutes into the video and yeah, him putting his face right in the line of fire of the disk made me cringe so hard. We expect to see failure in these videos and I was hoping so badly that nothing exploded
Having a face in line with 1 kilo of steel flywheel rotated to 6000 rpm on a plastic axis doesn't look safe either. Mechanical power enough to push your entire body. In front of your face.
What could go wrong?
Can't you make a basic pipe bomb by just chucking a piece of dry ice into a soft drink bottle, putting the cap on, and running away? This is basically the same thing but more so...
I wouldn't bother with the word "seems" in this situation.
How this man didn't die in this video is beyond me!!! brother! your guardian angels worked overtime!
Bro has a guardian army
OMG THATS THE MOST DANGEROUS THING I HAVE EVER SEEN YOU DO. That nitrogen container was a bomb, you NEEDED a pressure valve on that thing.
Self build pressure container next to an open flame.
What could go wrong? At it least it is not Hydrogen
For real, seeing this had me scared for him. I’ve seen that one video of the tiny Hero engine exploding on N2…
@@SoaringExperience The open flame not too much to worry:D exept if the rotational mass is gone wild, like the plastic shaft shear :D Then the fun begins ... :D
tbh I see a lot of people scared of this, but I wouldn't be worried, if its gonna blow up, it will be around the braze, and simply split in half, the bottom just hitting the skateboard and the top harmlessly going upwards, the fact it's brazed together is a (very crude) failsafe that should make it (mostly) safe
@@SoaringExperience isnt Nitrogen inert ? Are you thinking of NOS gas?
"Oh, I think I need to release the pressure!"

Idea for the next video>
Make a nitric acid + aniline powered rocket engine that was used on old jets and missiles from the 1940s. To expand on this, the main tube of the engine would be from PTFE(Teflon) or glass tube(prehaps quartz), fittings will be CNCed from 302 or 304 Stainless steel alloy because of nonreactivity with the two liquids, tubing would be also from PTFE and it would work with two
syringes. You would use the RPA program to make the ideal nozzle and strap it to a skateboard. Then, you would test it and see the effectivity of the almost explosive and potencially unstable liquid propellant mixture from the 1930s.
As i said, the perfect balance between backyard fun and chemical pipe bombs.
9:48 you also need a relief valve! That’s a bomb, sir!
Holy crap you scared the crap out of a few of us when you tried to use that tin can pipe bomb. I thought that was the end of your channel and there would be a "in memorium" at the end of the video. I suggest you get your hands on the same size cylinder from your local supplier in aluminum with liquid Co2 with the valve for gas withdrawl. it's filled with liquid Co2 but you will get about 200 - 300 psi statically out of it and it will be lighter than the cylinder you used in the video.
Keep up the experimenting and not blowing yourself up.
Also spinning up the heavy, metal flywheel for the first time without any safety and standing right in the plane it rotates... scary stuff imo
@@TheDoh007look up when Adam Savage did that. I'm on this side of the screen and it still made my balls tingle.
The CO2 tanks we used in paintball (readily available off-the-shelf and pre-filled) are closer to 800 - 900 psi. My own air cylinder is a 5000 psi model for compressed air only. I know Tippmann was experimenting with Propane because the tank pressure is a lot lower but displaces about the same amount of air as a similar-sized CO2 tank. The idea was scrapped because it turned out that Propane was, get this, flammable. No kidding! But if you leveraged the flammable property, I bet you could achieve a higher output velocity for the same volume of air!
But, yeah. That first can-tank scared the crap outa me, too!
Came down here to basically make the same comment. I nearly shit myself when I saw how thin that container was. Also I have to add emergency pressure release valves are your friend and will save your life.
@@RamDragon32 I doubt they'd abandon propane just because it's flammable, seeing how green gas for airsoft guns is just pre-lubricated propane.
Please stop shilling for Better Help they are a scam company that has faced fines for selling customer information on top of many other unethical processes.
If you redesigned the nozzle to blow on to the bottom of the disk, you would also get added thrust from the air. Plus, you could move the bottle toward the front of the skateboard for better weight distribution.
What an awesome idea! I'm impressed by how well that turbine worked.
One thing that was probably clearer during editing is that the turbine wasn't balanced well when it was mounted on the skateboard. I don't know how much that affected the performance, but it seemed to be experiencing quite a bit of friction. Also, if the shaft for the gear train was supported from both sides, that should help avoid the need for such high tension of the belt and reduce friction.
oh god that first nitrogen test was really a pipe bomb powered skateboard
Yeah, that was one of the more sketchy things he's done on this channel.
unless there is a over pressure valve :p
Which there was not :p
@@user-mw3ht5kp2p How would you rate that valve, without knowing the actual strength of the pressure vessel? It's complete bonkers, you don't fill liquid nitrogen into closed containers. It's even something they tell you at the places where you can get it - have the cap of any container only loosely sit on top, never screw it down.
@@graealex congrats u got the point
Reminded me of filling my old Air tank. Standing over a 30-year-old pressure valve and fitting
ON THIS EPISODE IM GOING TO MAKE A PIPEBOMB - integza without a safety value.
😂
Did you mean "safety VALVE"?
So drive turbine make electricity drive car next.
When he broke out the camp stove to heat the container, my heart started pounding. Extremely dangerous. Pressure relief valves are cheap, hospitals are not.
@@eviemoody Same, this was terrifying.
We're making it to the hospital with this one 🔥🔥🔥🔥🔥
this on a adult sized tricycle would work quite well I feel. room in the rear basket for the tank and drivetrain right over the rear hubs too.
I was flinching so bad when i saw the pressure gauge run up to 8 bars quickly while Integza was struggling to open the valve. That was a close call my dude.
This video has Faces of Death vibes.
There were *numerous* versions of it in this. I'm like dude... 😯
Welp! What else can I say that hasn't already been said by practically everyone else in the comments.
I'm really happy you survived the making of this video, Integza. I had my doubts there for a while.
I think it would be a better idea to attach the contraption to a bicycle. Then, you could more easily steer while using the turbine as a power assist. 😊
Integza you should have played the lottery instead of building this, because that was the luckiest set of days you will probably ever have in you life. It is amazing that you survived this madness unharmed.
Video idea: turn a gasoline engine to work on liquid pure nitroglycerin, sounds fun and dangerous :3
Tomatoes are disgusting!
Ignition systems? We don't need no ignition systems.
@@absalomdraconis but i think gasoline engine isn't gonna support the explosion of nitroglycerin, maybe diesel engine it's gonna work better
That seems safe. I like it.
That already exists (sort of). engines running on nitro-meth-ane (also an exp-losive)
Nitromethane is not an explosive.
Watching you run that turbine spinning directly at you with no shielding makes my toes curl. Holy hell.
No shielding? REAVERS!
You absolutely NEED an automatic overpressure valve, that releaves the pressure non-catastrophically before the weld or cups do, that self-made pressure vessel was basically a bomb!
I am impressed you didn't get blown to mush by that thing, but please make things a bit more secure from now on, that was scary!
I guess you're a new viewer?
@@isawathing8774
If you consider having subscribed over a year ago and having watched every video since and many videos from before that, yes.
But never in any of the videos I saw of him did he do anything as terrifying as this, which made me really afraid he'd die, even though I'd then not be able to see this video, so the video's existence already shows that he survived it.
Not just a bomb, a shrapnel grenade. The worst kind of grenade. The blast wouldn't kill him, but the shrapnel at worst could, or it could take out an eye and a few fingers/toes. Not a fun thing.
"blown to mush"? He'd catch shrapnel yeah but he's not getting turned into a pink mist from that.
So scary, this reminds me of when I put liquid nitrogen in my mouth, you can blow it out in a puff of smoke which I thought was cool. (not now!) However one time I had too much in the cup and it slid into my stomach. You can't feel it because it's floating on a layer of gas on your tongue. (Liedenfrost effect) Then I felt my stomach start to expand and I couldn't burp. So stupid!!!! Stupidest thing I've ever done. Finally I was able to burp, but for a few seconds it was scary!!! Don't drink liquid nitrogen! Ever. I could have won a good medal in the darwin awards. By the way you can buy burst disks that have different pressure ratings and have NPT threads. Google burst disk or rupture disk.
i love how you not overengineer everything and just try out to proof the theory
That's really cool. Especially with the nitrogen :D To help with steering AND with low wheel drag you could look at a human power speed trike. Skinny wheels, fairly light weight. All good stuff.
Oh, and the wobble in the hub and bearing of the wheel was SCARY ! ! ! I kept expecting it to snap off and the turbine wheel to race down the road, across the floor or bounce up and hit you. But also very cool at the time.... But what do I know. I actually LIKE tomatoes......
I love that you sit face first right in front of the fan as you test it for the first time. A failure would have been absolutely catastrophic.

Hey! I suggested this Video for a competition on your channel a few months ago! Glad to see it worked out! Awesome video! A new idea for a video, Thrust Vectoring! You've got the engines down, now make them more efficient!
crazy impressive my dude, the fact that the 3d printed parts can hold up to the torque is pretty cool!
As an engineer I have to say that was incredibly dangerous 😳. A safety valve alone would have saved your life. We love your videos and want you around to make more. 😊
See I tend to think of engineering and science education as the tools you acquire to not kill, maim, or destroy property while on the pursuit of the end goals you have in your career. You learn chemistry so you can understand how to think about chemistry and know when you need to delve into the risks of working with the materials or process. And the same applies for all things electrical and mechanical as well.
There’s few things that can’t possibly be done safely with enough effort. In my experience, most of the time people not being willing to slow down and solve the safety issues is what causes tragedies more than anything.
@lukegilles I couldn't agree more. I have worked several investigations where fatalities were the result of not slowing down and re-analyze the dangerous involved. This guy is extremely smart, and I have no doubt he looked back on this and was disappointed he failed to catch the danger. We all do this from time to time, especially in a hurry, and that's why " hazard analyzes " is the key to a long and happy life. 😊
I would advise against accepting sponsorships from better help if you can help it. They are not a good company. Very good video keep it up ❤❤
Same, I cringed a bit when I saw the sponsor.
@@carlobagnoli6746I unsubscribed. Will not support anyone that advertises for them. No one cares enough to turn down $$$ for the less than 1% who remember what BetterHelp has done, but I won't be part of supporting it for my own sake.
Cuh thinks his advise holds value
Hey dude, i do high pressure testing for a Living. For your own and others safety you MUST have at least one PSV and one mechanical valve as a safety feature for over pressurizing the container. This is extremely important, especially for cryogenic liquids.
I have once done some math to see if liquid nitrogen could be used as essentially "ambient temperature powered vehicle" (a "disengage-able" heat sink I could press to the LN storage to heat it up, increasing pressure.
Now, it does indeed check out when it comes to power etc etc., as you can do a lot of lightweight e.g. solar radiation collection etc.
What doesn't check out is material science. Do not try and keep LN contained. The presented massive nitrogen bottle in video? 200 bar. In sealed container in ambient temp boiling LN will generate 340+ bar. This is WELL BEYOND any steel tank capability. We are talking here about metal-lined carbon-fiber/resin multi-thousand-dollar contraptions that MIGHT NOT be even suitable for LN, or might require additional heavy support to increase strength and reduce risk of external damage. And then you have an issue of warming up the vessel, because it is very much designed not to do that, and materials aren't helping. And you prob want to avoid temperature stressing materials at such insane strains.
EDIT: now, I did think about like milled steel vessel that has like wall thickness >= internal diameter, but that sounds too close to "pipe bomb" for comfort xDDDD
Making a pressure vessel from two camping mugs and assorted firrints just fills me with the heebie-jeebies. Pressure vessles are nothing to mess with. The sooner you stop screwing around with stuff like that the better. Nitrogen-powered pipe bombs are no joke.
Not gonna lie, was a bit nervous about the nitrobomb you created at first. Glad you chose another solution. My suggestion for next project is to go bigger. Since the company has your turbine design, get another one made and double up. Double up the turbines to make a bicycle drive with double gears, double air lines and use the same nitrogen tank with more bar to allow for the double turbines.
The pre-fragged flywheel spinning at 6k in line with the rider doesn't bother you?
The container was nice too but that turbine... 😯🤦♂️
i love all the snappiness!!!
I really enjoy the borderline craziness of most of your projects , All while doing something that uses rather scientific principles . Very entertaining channel looking forward to more of your content in the future .
To prevent the steel container from bursting add a pressure relief valve, many of them are adjustable. However, the higher the pressure required the more expensive they tend to be.
Oh lord The Better Help
Wtf?
I love big tomatoes! Also called 'pontoons' or 'bazooms'!
terrible sponsor alert!
The worst company!!! So sketchy.
You'd think people would be aware of why to avoid them now, but nah. This is why we can't have nice things.
so clearly you need to make a V2 now
also the dang thing sounds like kirby
I think it would be amazing if you converted a go cart from using a ICE engine to using some nitrogen gas powered turbines. With the go cart, you already have a frame and steering setup, imagine a few more of those SLM turbines, the throttle controls the kPa aimed at the turbines
I think that with a little bit of optimisation you can go much faster!
- balance the wheel of the turbine
-give it an enclosure (a stator basically) that can also support it laterally (it shakes a lot when you blow the compressed nitrogen)
- keep the nitrogen tank horizontal to get a lower center of mass
- wear a helmet so you would feel confident go faster!
We can get to see some nice speed records with this thing a think!! I love you contents every time!
Would more nozzles help ?
@@AndrejMejac yep, that’s a good idea! Probably adding another one on the other side of the turbine would solve the shaking problem since the force would be symmetrical. I did not understand if the turbine is symmetrical, but if it isn’t you can probably mirror it and stuck the two together
you forgot the step "learn how to avoid making a fucking pipe bomb in the future before continuing projects"
The bearings he is using are greased, these are robbing a lot of power as there is not a lot of torque and high rpm. This application calls for oil, you should get a bunch of extra oomph just from that. But then you have to deal with oil, oil pump, etc, so maybe not worth it.
@@pierregarbo8628Symmetry is a good point. Perhaps there is an optimal number of nozzles, depending of in-flow, nozzle size, outflow, mass distribution and such. Enclosure could lower loss, i guess, at least at one side.
Nice explosion is probably a bonus.
Edit(2 more sec of thought)
All these 3d printer yt guys will do absolutely anything but machining…
Tools complement eachother not replace!
Almost all of your failure points in most of your videos could easily be solved with a little machining and making your own metal parts.
Love your vids!
machining requires a ton of initial cost in buying machines, crazy time in setup, and probably another cost of mcuh more space. All that for some parts to not be machinable and leaving most of your machines unused for a while and the initial cost not being paid back just makes metal machining unrealistic.
the parts he needs to be metal are metal, like that turbine and the aerospike he made a while back, which he can solve easily through a machining service like he used in this video, or the (unconventional) metal infused resin like he did in the aerospike.
most of the stuff in rocketry and engines anyway are super complex to machine
machining initial cost not worth it, can be substituted with services, and even with machining will likely not solve many of his problems
3D printing is easier and takes less time usually. Machining is an art of it's own
@@brandonzhang760A basic, compact manual desktop lathe could do most of the basic things that are imho problematic in a lot of Integza's builds (like the hub/bearing adapter for the turbine in this video. So much wobble would be avoided) and really doesn't cost that much. We're not talking about doing complex 5d aerospace parts, just basic axles, bushings, adapters, nozzles, that sort of thing. The sort of parts that benefits from being accurately round and concentric. One step beyond the lathe is a simple manual desktop mill (doesn't even have to be CNC). Again not a MASSIVE investment (probably similar in cost to a high spec 3d printer like a Bambulab P1) but gives a lot of capability.
@@TheAverageDutchman well then it’s a huge cost for not much usage
@@TheAverageDutchman The big problem with these kinds of mini-mills and mini-lathes is their unyielding rigidity of a cooked noodle. Cutting steel on them requires babying to such an extent you can't even use carbide inserts, they wouldn't be in their optimal load/RPM ranges. You'd really want a more rigid machine for working anything but brass and aluminium. And that comes with hella price and space. A reasonably cheap desktop CNC mill that *can* cut steel, I.E. Carvera, runs the cost of 3-5 high end printers.

The reality of the situation is sinking in, did I really just watch a man use a V2 rocket component turning it into an engine and mount both the engine and gearbox onto a skate board whilst being held down G clamps. Which turned 5 years of mechanical engineering and a full apprenticeship where I learnt the basic principles of engines; suck, squeeze, bang and blow, into a workable fun thing... Hmm, whilst my bingo card did not have that on it, it has made my day. Definitely deserves a like, subscribe and comment. Cheers.
I've seen a lot of people on youtube electroplate 3d printed parts. I've also seen them electroplate most of the 3d printed part and then remove the plastic and fill it with a metal like tin. I was thinking some sort of project that involved this would be really interesting, espcially since I haven't seen anyone compare the strength of these parts and the thermal capabilities. So an idea that would use these parts could be a mini MPD thruster project involves creating a small-scale, functioning model of a type of electric propulsion used in space. The thruster works by accelerating ionized gas using electromagnetic fields to produce thrust. In this DIY version, key parts are 3D-printed and then electroplated with metals to handle the extreme conditions and high currents involved. It’s a project that combines aerospace engineering, physics, and advanced manufacturing techniques to demonstrate a complex technology in a more accessible format.
Its an interessting technique for sure, only problem with plating is that you lose dimensions. If you need an exact diameter or fitting threats in a hard to reach area its a pain in the ass to get right. But all in all its for sure interessting to do/see.
4:19 face next to a 1kg rotating mass
10:05 is the pressure raising? I think I need to release the pressure
Man how many chances are you taking with your life!!
Man is a true engineer, putting everything on the line for some fun
If he had just stood infront of it an not to the side in the path of potential shrapnel he would bee sweet. He just wanted to get some comments goin i think 😂
The pressure vessel was mild though. 8 bar at that small of a volume would probably give you a good scare and ring your ears but you'd be fine
After saying this, you then proceed to hop in a car and travel at speed with oncoming traffic separated by only a couple of meters from yourself.

Estás de parabéns Joel, estes ultimos videos estão melhores que sempre! É sempre bom ver um português a ter sucesso no mundo dos estrangeiros.
The lack of a safety valve on a sealed container filled with LN2 really scares me, I hope you don't try scaling that up without one.
That was totally nuts. Super, super stupid. Stay safe Integza.
No point in safety valve if you don't even know how your home built pressure vessel is rated. You can do some educated guesses, but that's not even close to being safe, even with a valve.
And btw safety valves can be dangerous too, when they suddenly release. I had an additional air tank to supplement my compressor. It had a safety valve at around 10 bar. When it suddenly released, not only was it super loud and could have easily damaged hearing or injured someone close to it, but the sudden shock literally popped the paint off of the vessel.
I guess the bad weld was the safty valve ^^
It's just brazed together.... it's not like it would handle to much pressure either way
Video idea: Build a Rube Goldberg machine with the most liked/ functional projects (I think it would be awesome for a 2M celebration)... Obviously using the ionic zeppelin it's a must (please)...
Honest suggestion here. I believe the efficiency of the turbine would increase significantly if you designed a sort of capsule or something so that the gas can only go through the turbine, instead of escaping/just bouncing off of it.
You can solve the issue with steering the skateboard if you have your weight towards the front of the board. Having weight on the rear caster creates a stronger positive feedback loop that skateboarders unafectionately call "wobbles". Downhill skateboarders also mitigate this with lower degree truck angles in the back of the board which means you get less turn for how much the skateboard truck leans.

Thanks for watching

I loved this, maybe continue on with the rocket theme and show how the v2 engine worked
I REALLY want to see you do this with 2 turbines, air jets, and gear systems! One powering each rear wheel! Maybe you could build a little soapbox derby car with steering!
I would love to see a video about what you've learned about the strengths, and limitations of 3D printers, with design tips for making better prints
"Oh shit there's no steering" sums up my life right now
:peepocry:
Weirdly that was probably the least dangerous part of the video.
It actually has steering
I love watching your ingenuity.
A homemade brazed pressure vessel that you heat for good measure, a sintered flywheel, and rockets, all right next to your face. I applaud you. Shake hands with danger.
I'm not gonna lie, the first time you spun it up I was terrified of your face being so close to it. Stay safe man!
Yo, that arc is INSANE. When you finish Water 7, you won't stop.
Huh. Didn't know JLC3PD does metal printing now. Cool.
Holy 🍅 bud... putting alot of faith in that printed turbine handling those rmp/cold temps that close to your face 😬😅 cheers for another great project
NO FEAR!! :p
Also putting a lot of faith in a thin-walled, brazed, pipe-bomb.
My concern was less the flywheel, and moreso there not being a bearing on both sides.
Granted flywheel explosions are a valid concerns, doing that math and if need be making a container for it (although this only does so much, some FES systems are put in the ground for this reason if i remember correctly)
The Abram’s tank has a turbine engine. They sound crazy and can go pretty darn fast for main battle tank.

A clutch might help a lot. Get the disc spinning like a flywheel before it engages so you can gear up for higher speed.
I think you should make a more robust system and put it on a bicycle!!! That should be one of your future videos for sure! Good work as always!

You know how you can potentially inspire someone to try to build their own rocket but they end up building a pipe bomb instead? Promoting betterhelp is like the mental health equivalent of telling people to actually go and try to build a pipe bomb while promising it's going to be a rocket
To kind of answer your question early in the video; maybe you'll come up with the answer by the end. They don't make turbine powered cars because the exhaust comes out so hot that it burn/melts anything that gets too close to it. I remember seeing a video of one of Jay leno's jet cars, yes he has more than one, melting the front number off a car that pulled up behind him at a stop.
The timing for your One Piece joke is spot on for me. I just finished compressing 1071 episodes & 15 movies from it, and put it on my plex server yesterday.
You should try to modify a rc plane with a jet engine!!
That's waaaaay too safe. He should make one powered by dinitrogen tetroxide and hydrazine that he made.
Watching that turbine wheel? spin without a guard is terrifying.
That turbine should make hundreds of horsepower. Use multiple nozzles to blow air in many places around the turbine instead of just one place.
Loved this one... I'm sure you know that you can make most anything fly/float if you can get enough air flowing over it the right way... and if you can keep it from spinning itself apart. I think that could be a very fun video... Mark Rober did this in one of his videos... I just think you could have fun with it by spinning apart a ton of disgusting tomatoes. Maybe fill the tomatoes with different chemicals, or coat them in different substances all in an attempt to get the best reaction as it blows up... I mean spins apart.
10:10 it's litrally a delayed explosion bomb
Would be interesting to see how the Tesla turbine works in the exact same setup
Tesla turbines are failure..ive tried 3 designs and it is super weak and steam thirsty...this turbine he uses is called De Laval turbine and its probably best turbine anyone could invented
Suggestion for future video: diy fridge/freezer. Using a motor and 3d printed parts to make a basic compressor and fashioning all the other bits required.
Wow you're the first I know to advertise that their 3D printing service includes metal, that's very interesting!
I love tomatoes
Disgraceful
You don't belong here
Eww
@@the_untextured😂😂😂 you can say what you like...but you know wouldn't die for you!!! 😅
Bruh
Hehehe! Well i think we all need it's a turbine powered tomatoes slicing machine!
Great video!
You missed the oscillating hook machine that’s fairly common and I would have loved to see more on embroidery machines but that may have been redundant. I repair and operate sewing/embroidery machines for a living so this was pretty cool to see. Really solid explanations and totally spot on. Great job!
This is about as close as I've ever seen a human come to "running with an unshielded reactor core".
This is Reaver-Class madness.
Stop promoting better help it is a shady company and has some bad track records
Shady?
That home made tank is by far the most dangerous thing I’ve seen you do on this channel - and you’ve done some sketchy stuff. Never mess with gaseous pressure vessels if you don’t know what you are doing, they are incredibly dangerous!
Turbines are incredibly efficient at a specific very high rev range. Cars go fast, slow and everything in between so the car turbines use lots more fuel.
It would be amazing if you went ahead and build a full go-kart out of 3D printed parts. I am sure it would require a lot of designing but you have that under control. It would be great for all those people out there with time and a 3D printer. Anyway, you are amazing, keep up the good work.
I'd love to see turbine powered go-kart that actually uses one of your jet engines.
Welcome to the Onepiece fandom! If you are on episode 234 you have a lot to look forward to!
Hes back with the jets yay
Video idea: How about a general purpose Propulsion Test platform with sturdy wheels, somewhere to sit, steerable, that you can use for texting things like this and other jet engines or turbine ideas? A ready-to-go rolling chassis as a template
Kudos on having the flywheels rotation allowing it to drive right into your face if it ever comes off
The reason why we're not allowed to have more control over what we burn in our vehicles is because the poor oil companies would be sad
Joel should make some sort of turbo-powered food-processor. It's very annoying to try to manually dice vegetables, and he could probably use it to turn tomatoes into ketchup. Maybe it could be as simple as replacing the blades and motor of a fan (wouldn't that be a fan of Theseus? 🤔) 🍅🔪🍟
Video idea: Jet powered tomato launcher? Love your work
The fact that you had “she’ll be comin around the mountain” playing in this video at all is nuts lmao
