To help with the hydrogen peroxide coming out of the turbine it could help to mount the catalysator vertically; the fluid stays at the bottom and has a better chance to decompose before exiting to the turbine.

The catalyzer needs to be vertically mounted, bottom fed, and have a high pressure reflux column with baffles to recycle peroxide that hasn't decomposed.

I had NO clue catalytic converters could do that to H2O2! Freaking awesome and really does make things so much more practical.

To help with the H2O2 getting into the turbine, you could try a 2 stage reaction chamber. So, have the exhaust of the catalytic converter feed into another plastic tube containing the potassium permanganate doped ceramic thingy that you made in an earlier video. Then have the exhaust from that tube feed into the turbine.

Maybe to improve the decomposition of the peroxide you can have the pump run the peroxide vertically into the catalytic converters. That way the liquid stays at the bottom of the converters and the steam rises up into the turbine.

Im thinking it might be advantageous to mount your reaction chamber vertically, that way you can submerge the 2nd cataliser section, let the H2O2 buble up into the 3rd section, this should help limit the amount of liquid that gets pushed through the turbine. Speaking of the turbine, lm blown away you didnt use the tesla turbine as a comparison. Great video as always.

You could scavange a fuel injector and fuel pump from a car. That would give you a good spray pattern into the catalytic converter and as really high flow rate, and granular control over the reaction by manipulating the injectors spray rate by controlling it with some sort of PWM generator (arduino or similar) and some transistors or high speed relays. Cool project!

I just followed a course about hydraulic turbine design and to see you put that into practice made my day. Tip if you want to build a good turbine, just look up the Cordier diagram. In short, it tells us that the size and flow rate of a well-designed turbine are intertwined (there are formulas for this). And depending on your flow rate, I expect you need to go smaller.

Future idea: Get the community to send you 3D models of rocket nozzle designs that you can print out and test against each other to see if crowdsourced engineering can improve on existing designs

I've always enjoyed your videos but something about the way you made this one is just very, very good. Slightly more chill, really just analyzing different aspects of your design and the project at hand. Not sure if this makes any sense but I really enjoyed it

Just a thought as well, could you accelerate the reaction by preheating the peroxide before it hits the converters. lastly hook the turbine shaft to the pump and use a valve to throttle it?

I’m really enjoying seeing all these engines and rockets. It would be really interesting to see you put all this experience toward an actual small scale rocket.

I see two things that needs an improvement, the catalyst tube need to have the output tube it must be in a higher position respect of the input side, so the peroxide can’t exit in a liquid form. The second one it’s the weight of the impeller, you can hear the rpm ramp up sound. Good video.

This was incredible! Thank you for your videos! Design recommendations: Move fuel tank/source away from the AB plume & Clamps, or otherwise secure the high RPM point of failure to a surface so you can continue to create? Lol. Also, if the Aluminum turbine failed at those RPMs, the table & bow tie will do their best, but... NEXT BUILD! It might be wild to use your engine here to power a Strandbeest of some sort. I'd imagine it would look like something out of Howl's Moving Castle! You know... For strictly demonstrative purposes & TOTALLY not to create a giant mechanized death spider ala Wild Wild West. 🤔

A steam-powered automatic shooter of some sort seems about right. That high-pressure steam has a lot of potential. Oh and about those broken endmills, try single flute endmills for cutting aluminum. I use mostly 6mm diameter single flute at about 10000rpm, 0.8mm depth of cut, and 1000mm/min feed. It blew my mind and cutting has been much easier since!

I'd love to know how many uses you could get out of those cat converters. Not a bad video Joel, and keep up with the CNC machining. Whole new possibilities there mate.

So, first thing as mentioned before: Vertical placement of the catalysators to prevent liquid going into the turbine; Secondly you need more steam nozzles to hit the blades, and maybe a redesign of the blades themselves :) Take inspiration from a turbo compressor ;)

8:05 @Integza I have seen in previous videos that the endmills * go into the material too fast. That's probably why you broke so many. That's also at least one of the reasons if not the reason why your cnc machine makes weird noises. *English isn't my first language, so I'm not sure if that's their name

This is on its way to becoming a torpedo, suggest making stators and a reduction gear box to turn propeller an see if steam generator can power an RC torpedo, multi episode build. Keep up the good work

I’m so happy you are finally seeing promising results! Good job Joel, you’re a genius!

The project i suggest you to make is to make a RC plane powered by Pulse Jet Engine

As some people have already suggested, mounting the cat chamber vertically could help decomposition efficiency. If you do that, you could: Video idea: hook up the turbine to the H2O2 pump with a modest gear ratio, give it a little puff of compressed air to get going, and you have a super dangerous, potentially catastrophic, and hopefully entertaining situation on your hands 😆

00:10. I would love to see you put a gear reduction on that, and use that torque to crush tonatoes, and other stuff

Video Idea: Making an RC jet-powered boat!

I didn't know you got a metal cnc, thats sick. You should remake some of your best 3d printed rocket engines now that they wont melt so easily!

Your videos are my go to when I start feeling down. Thanks for being an amazing human.

Video idea: make a HHO or Hydrogen gas generator and run a small internal combustion engine off it , this whould essentially make a "water powered" engine .

I want a 3d printer! So here’s my thought on improving the output! We’ve gotta separate the unspent h2o2 from the steam. With the current design, the high pressure is giving you the same problem as with the permanganate. High energy fuel is shot out of the end because the catalyst works too well. If you added a chamber that allows the steam/peroxide mixture to fall vertically into, the peroxide will fall to the bottom, and the steam can be vented from the top. You can connect the top of the separation chamber to the turbine and loop the bottom back into the catalyst chamber. That should both improve the efficiency of the reaction and protect the turbine from peroxide erosion. I don’t think rotating the catalyst chamber vertically will improve the output as well, because you’ll limit the amount of catalyst the peroxide has exposure to. The top converter will really only be exposed to steam. I say keep it horizontal and separate the output.

You should do a project on a rotating mass balancer, considering you make many high rpm spinning stuff for your projects. Balancing your spinning projects very accurately would really let your projects perform much better and plus it would be fun to watch you do a video on trying to make a balancing rig on your own!

That was amazing! I don't know if this would help , but maybe add a tank and a check vault ( one way valve) on the end of the chamber with the catolizors for it to be able to build pressure before it enters the turbine , have a valve between the compressor tank and turbine so you can close and open the vault once it builds enough psi

That was so cool. What shocked me the most was the overall pressure coming out as a chemical reaction.

You can improve your design by making higher tolerances. You can also remove the grease from the ball brings using a solvent, instead us a thin silicone based lubricant often found in spray cans. This way you will remove some of the friction caused by the grease. Another thing you can try is to balance your turbine, set it in a pace where it can be suspended upright, the heaviest point will then move to the bottom, then you can either subtract weight from that side or add some to the other side. Keep repeating this until wherever you rotate your turbine, it will stay. You can also try to improve the power of the turbine by attaching some gears to the output shaft in order to provide more torque.

Theme for a future video:- The electric jet engine which you just made reaches several thousand degrees at the nozzle, what if you convery the exhaust into *plasma*, and see it with a thermal imaging camera, you can do this by attaching a high volt power supply wires at the exhaust and make the part of wires at exhaust with tungsten to prevent melting. Improvement sugesstion:- you can use a porous thing to store Potassium Permanganate and pass the hydrogen peroxide through it, I think it work better than platinum or palladium.

Video Idea: make 3D printed hovercraft. You can use compressed air to allow the hovercraft to float and to propel it forward.

I’m a Tool maker i would recommend maybe 4140 or another cold roll steel for your components. maybe even Some light stainless steel. often times the metal i use to make armature shafts for large companies at work is really hard stainless steel or pre heat treat 4140

12:02 …this dance = new sub…keep up the good work and great dance moves…cheers..👌🏼✌🏼

Would be really interesting to see how this turbine design would compare to a tesla-turbine Edit: and also compared to a pelton turbine

YES!! Finally working with CNC'ing and working with metals instead of just plastic! WE WANT MOARRR POWWWEEEEERRRRRRRRRRRRRRRRR!!!!!!!!!!!

Powerplants use a kind of "bent pipe" system with 2 outlets to separate the steam and residue liquid by using their density diffierence to get "dry" steam and prevent their turbine from being damaged. maybe put something like that between your steam generator and turbine, depending on how you set it up you might even be able to reuse the residue fuel

Interesting idea

When you get the catalyzer working better, you should mix fuel with the output and make a steam/rocket motor.

This might seem like a lot of work, but now that you have access to metal parts, it would be awesome if you could make a rc submarine, powered by some sort of stirling engine or something like that. Few servos, a mini cam, and off you go to conquer the seas!

Video Idea: My two boys (8 and 10 yr old) and I (46 years old) have enjoyed all of your videos and have watched them multiple times. We love the great combination of history, science, engineering and humor. Thanks so much for your videos. Our idea for your next project is to build a Newcomen Steam Engine.

It would be really great if you tried to build a steam-powered rocket like the ones used in World War II, but of course smaller 😅 Really instructive video, once again extremely cool to see what was built in the past. (Even if it was not used for good purposes)

you could try wrapping the cats in an electric blanket and heat them to like 80C might help with the decomposition reaction, more temp is normally more better with chemical reactions. those cats may need re-activating every once in a while the metal will oxidise inside them which may make them perform better actually, PdO and PtO are better oxidation catalysts than Pd(0) and Pt(0) metals.

The Astronomy and Nature channel has a superb series on how the Germans built the V2 including the H2O2 generator and turbine. Your problem is that you are not applying nearly enough pressure, and then it’s not clear you have enough volume flow (remember that everything flows really fast in a rocket engine in order to produce enough power). The V2 H2O2 and permanganate were pressurized to over 400 PSI which was the head pressure to the turbines, and the steam then provided the volume flow at that pressure to run the turbines. The compressor connected to the turbine then compressed the fuel and LOX into the engine I think at a higher pressure still due to mechanical advantage but not sure about that. Watch the V2 series to find out for sure.

This video got recommended to me and now I have found a new creator to binge watch before sleep. Nice! About the design improvement though, as many said I believe mounting the catalysts vertically would help reduce liquid H2O2 escaping and getting into the turbine. What if another, smaller turbine was placed just after the catalyst? The steam could rotate that smaller turbine which will require less force, and increase the pressure, maybe even install tubing downstream of the small turbine that decreases in size gradually until the main turbine inlet, which would help increase the inlet pressure even more.

Video idea : make a mini steam powered boat

A way to possibly fix the wasted hydrogen is to have 2 catalyst tanks and insert smaller amounts alternating into each. This might provide constant flow of power.

Really impressive project, man. Here's a couple ideas 💡 if you're interested: 1. Polish the turbine and oil the chamber to reduce efficiency losses in the turbine itself. 2. Stage multiple turbines with increasing radii to extract more of the power from the steam as the pressure drops. 3. Use some kind of liquid separator to eliminate fluid passing through the turbine. 4. Use more catalysts in parallel rather than in series. 5. Drive the pump through a heavy gear reduction from the turbine, so that acceleration creates a greater supply of steam.

You should make a rocket powered blimp! Or just a regular blimp would be cool too.

Video series idea: see how advanced of an engine you can make, using only water and electricity as your fuel. Create a 3D printed electrolysis chamber to separate water into HHO gas, then use that HH0 to power a simple sterling engine, then work your way up to a steam engine. Can you make a HHO powered steam jet engine? Can you make a jet that runs only on HHO?

I'm so happy that integza now have access to metal parts!!! Now the things are going to be awesome!!

VIDEO IDEA: you could build a Pulse jet airplane like the V1 but without the bomb. But Rember you could try to make a pulse jet without you having to spray air into it.

I'm so pleased that you're working with metal.

Can you do a video where you compete all your engines against each other? You've made so many but a head to head competition of which one is the most powerfull would be interesting!

You have upgraded the channel with that CNC! You could add an acumulator tank before the turbine to retain the liquid and have only steam going into the turbine. That's used on cooling systems to separate liquid and vapor coolant.

I'd like to see some sort of steam powerd catapult or Trebuchet of sorts that might even use a flywheel to spin up and build energy before lunch

You need to make a tank, in a 3D printer (PLA So that if a part breaks it will be easy to replace and also the tank will be lightweight) OR in a cnc (Aluminum It will be really good, strong and realistic). That the head (turret) will be a rifle that can shoot sponge balls. In my opinion if you make it out of aluminum or half PLA and half aluminum in the turret has a rifle you will be the first to build such a thing. And another idea to put a tomato behind an EDF motor and behind the tomato a knife or a small mud bath (mud box)

It would be so fun that if you make a "steam" powered fuel pump with a turbo jet engine or a rocket engine mounted to the bike/skate board (the oxygen generated from the steam turbine can be the oxidizer for the rocket engine)

Love the historical tie-ins! Idea: Attempt to bring a historical concept to life from a project that failed like the Avro Arrow!

1:08 it was actually not an intercontinental ballistic missile, it would be classified as an intermediate-range ballistic missile, maybe even a short-range ballistic missile.

You should have a checkpoint valve between the pump and the "catalyzer" chamber. Also the decomposing Chambers should be oriented vertically. The idea behind this is to keep heavier liquid down and steam will leave and go up reducing the amount of peroxide passing through to the impellers.

Honestly I would love to see if you could use the turbine to remake a V2 rocket. I’d tell you not to put explosives in it but i have a feeling this video already puts me on some sort of list so it’s up to you man.

Make a thrust tester for it , Measure it. And put it carefully to a plane

You could try to make a rocket and mount the turbine inside the nozzle so that the rocket pumps its fuel without the need for steam. That pump could be started with compressed air and then become self sustaining.

For a side fed turbine design you should have the exhaust outlet fully open to the atmosphere. Also if you look into A/R ratio of turbine housings you'll probably find the inlet is too small relative to the turbine diameter. Since you're working with a small-ish flow of gas I'd suggest down sizing the turbine wheel. It'd be helpful to get a pressure reading from the inlet side. Cool vid!

Future idea: this has always been a tough challenge for me to come up with an idea suggestion for your comments as it seems like all the best ideas are already posted or already in a video you've made in the past. All that being said, I know if I had a 3D printer I would thoroughly enjoy making model rockets and instruments of my own design (something like lap guitar, electric fiddle, monochord etc). Hope this gets seen, going to keep trying and comment in hopes of being someone that might receive a 3D printer, if in fact you still do that now and into the future. Thanks for all your great videos, I love your presence, your presentation of your various builds, and have learned so much in the year or two that I've been subbed.

You should start a series where you make an engine every episode and produce electricity with it and compare which are the most efficient and with the most efficient engines you power a skateboard and go through a drive through

Idea ------> You can make a working drone with rocket sides

Since you know so much about rockets and engines you should try to build a small scale v2 rocket and use parachutes to recover it

Integza, you could enter the era of electric vehicles by recreating some Tesla creations and updating them. Integza, vc poderia entrar na era dos veículos elétricos, recriando algumas criações do Tesla e atualizando-as. Sucesso! Quem sabe uma impressora 3d não vem pro Brasil 😍

Video idea: make a steam engine powered tomato 🍅 death machine aka Juicer🤭 Also, A longer tube and keeping it vertical will minimise hydrogen from escaping and give it enough time to react.

"and if you dont love your cat that much" lol not only have you earned a new sub, but i will not ff through your ads.

Here is an idea 3D printed steam powered rc plane. You could find a way to funnel the steam to create enough thrust to create lift.

Damn, why haven't I gotten your channel recommended earlier. Love the content, love the way you bring in both history and engineering in a relatively simple way so a guy like me can follow the video and understand the topics you talk about.

Put the CC tube vertical with the h2o2 input at the bottom, and use a small "nozzle" to spray the h202 up into the CC's. This should keep a lot of the liquid out of the turbine.

Your channel has helped me to realize that it's not actually the entire Internet I detest.

First improvement I would make is the bearings, upgrade to a set of Abec-8 high speed sealed bearings. Next design a mill a Delavan nozzle for the output of the turbine to increase the exhaust steam and produce forward thrust. Next increase the overall volume of the expansion chamber and mount it vertically to minimize liquid waste and increase usage overall. There is a massive amount of potential for this design. Bravo Integza 👏 Mr.Tesla would be very proud of you.

Love your videos! You could build a steam powered coffee machine next time! If you have to do an all nighter 😉

Try mounting the catalyzer vertically and adding a chamber to capture the extra liquid peroxide.

Idk how I got to this channel but I’m 4 videos in and I love it here.

Totally dig the music track slapping together the 3d print prototype!

Future idea: make a plane named Integza 1! it could be rocket powered, jet powered, electricly powered or powered using these co2 cartrages. Even better, make a tomato bay that can drop tomatos out midair and use it to bomb things!

Video idea: I've seen a few steam bikes before, but with this safer and more compact method generating steam I wonder if you could make a steam bike that doesn't require the extreme heat and flame of a boiler. Plus this is safer, and far lighter.

Love it! I think the power source is great by far compared to 3d print one. To avoid waste try using it vertically and let the reaction occurs below with the output on the top. For the turbine, try using some pneumatic tools instead. They are much more capable of high torque at least.

watching your videos feels like everything is packed very tightly together, and you're trying to find a spot in frame to fit your face. interesting choice there

Video idea: you NEED a testing chamber. Something Portal themed, in which tomatoes are being tested against your creations. May you prevail over all the Chell that will enter the test chamber and rid the world of tomatoes. #TomatoesAreDisgusting PS: I actually believe that measurement of thrust, efficiency and an overall profiling of the various rockets/turbines/engines would increase your per-revision improvement quite a lot.

Fantastic video! Your willingness to tackle even the wildest of projects is something I admire greatly! Keep up the great work!

Well done! Great job

i think adding an expansion chamber could come in handy. and rotate your catalyst chamber vertically, with the inlet on the bottom, and outlet on the top, for both the catalyst and expansion chamber.

Hello there Integza, i think it would be pretty cool if you could 3d print a cutom plane and attach one of your pulse jet engines to you, i love the sound they make and think it would be pretty cool watching it fly, I think it could be put in the fusilageof the plane as its not sucking in any air and have the exhaust out the back.

Hey Joel! Great video again :) You should orient the catalyst chamber vertically, having the hydrogen peroxide being pumped in from the bottom, steam exiting at the top. That should increase efficiency by increasing the yield of steam, as peroxide being forced upwards gets catalyzed as well

This video earned you a sub. Good stuff. Thanks.

You can also add a "catch can" between the catalysor and the turbine (an air tight tank), so any liquid can be collected there before reaching the turbine! Your videos are always educationally entertaining 🤣. Cheers

you should make a *high speed camera* (a camera mounted on a rail that goes really fast) it would be a great opportunity to test new designs and i think it would be rlly fun

Video idea: You've successfully created all sorts of crazy engines, so how about the Adams-Farvell rotary engine, where the pistons are turning around a stationary crank shaft! :D

I think a good idea for a build video would marry this chemical reaction into a rocket with an r/c controlled throttle. You could even see this power your skateboard without the weight of the turbine and even see this take flight like the old pulse-jet winged bomb design w/o the boom of course! And you could even 3D print the rocket body & nozzle all at once after you figure out the proper nozzle for optimum thrust. Or maybe not? IDK I hate tomatoes too so either way this would work at blasting those across a yard or even blasting holes in them if strapped down.

building a steam powered go cart would be cool

I fully appreciate the hard work and planning that would have gone into this. I do possess a cnc router , a 3d printer but I lack the enterprise and interest you have. Thanks for spurring interest in these type of activities.
