[@etelmo]

Correct me if I'm wrong but without a stabiliser like EDTA or citric acid wouldn't the permanganate break down to manganese dioxide over an hour or so anyway? Like that would be the brown colour seen on the ceramic... But then again those very same stabilisers generally prevent metal ions reacting to decompose hydrogen peroxide (that's... Kind of their point), so they would probably interfere with and slow down the reaction? It's been ages since I did any related chemistry, I'm just here for Tom, that sexy sexy man.

[@BackYardScience2000]

@@etelmo yes, a stabilizer would slow the reaction down. But not to the point that it wouldn't work at all. It all really depends on what the stabilizer is and how much it affects the reaction. Manganese dioxide does work as a catalyst, but it's not as fast acting as the permanganate. So you get diminished performance, but not to an extent to where it's not useful. Also, I'm not sure if you're referring to the permanganate breaking down spontaneously over time, or while in the reaction? Yes, it does break down into the manganese dioxide upon reacting, but no it won't break down while sitting there waiting to react with the peroxide. As long as it doesn't come into contact with a fuel, it'll be fine. Those catalyst ceramic pieces could be soaked and dried and stored for long periods if they are kept in air tight bags. If left out, they may degrade slowly over the course of a few weeks..... Maybe.

you could try suspending the MnO2 or KMnO4 with the 3d printed ceramic part to particle impregnate the part, and then calcine/anneal the catalyst to the support (around 600C ish). it should prevent the manganese losses and prevent the blockages/high back pressures. the flow through the support should increase the surface contact with the heterogeneous catalyst improving the mass transfer making the reaction go boom boom faster

[@tswdev]

Video idea: attach 6 of these in parallel like the Atlas HLV rocket, have the tip contain a CO2 cartridge (this would distribute the pressure by all 6, should be about 9 bar pressure to each and use a vent valve to control output pressure, you dont need all co2 contents, so it doesnt have to be efficient but its lower weight and size, plus the vent will create lots of smoke which is cool for video!). Use a membrane (like the ketchup bottles) to separate the water from the fuel or a burst cap (plastic film?) if its not water proof enough, this should make it all a single component with no need for glue or any other weak points. Bigger == better! That should make an awesome video!

[@LabCoatz_Science]

What if you used the oxygen created in this case to fuel a hybrid rocket? You could create another gas generator that makes something like hydrogen or acetylene, mix the flammable gas with the oxygen in a combustion chamber, and ignite the mix.

hydrogen peroxide has been used as an oxidizer in hyperbolic rockets (aka the propellant ignites itself when combined). but normally they use Liquid oxygen because you get a higher specific impulse (basically gas milage for rockets)

[@philippreuner2508]

Video idea: Try making a turbo pump for your liquid fueled monoprop engine. That would replace the syringes and could give you (in theory) a much higher chamber pressure and therefore more thrust.

I remember seeing something that used simply four light sensors controlling two motors driving an altazimuth mount, and a shade that will just barely shield those if it is pointing straight at the sun. If it is pointing slightly off, one or two of the sensors will receive sunlight, and thus cause the motors to turn the contraption until it is pointed directly at the sun.

[@alden1132]

@@zuthalsoraniz6764 That's a clever idea. It's similar in concept to one of my own imagined possible solutions, and seems like it's relatively cheap and simple. Thanks for sharing the idea! One of my ideas was for a more "passive" solution, like calculating (using math that's currently beyond **me**, personally) whether or not there is an "optimal" shape for a parabolic mirror that can be aligned with the "arc" the sun describes as it moves through the sky, so that *less* effort is needed to keep it in the optimal position.

[@peterjohnson9438]

as long as you place the device in a completely clear area, you can create a simple bit of control software where the logic goes something like this... For initial startup, rotate entire assembly for the full range of motion, at a 45 degree elevation. The angle where you get the highest voltage out of your cells is the sun position. Rotate assembly to that and sweep through elevation from 0 to 90 degrees, record the highest voltage, rotate to that. Done, you're facing the sun. Following that, every 5 minutes, sweep the device left to right by a small amount (like +/- 10 degrees) and record the highest voltage, lock to that, then adjust elevation. Sleep for 8 hours if voltage drops below a certain threshold or unless the threshold is tripped again - that's your night mode. Once night mode ends, revert to initial startup. You can make this logic work with a cheap Arduino. You'll also need a car battery, two motors and two motor controllers, some solar panels and a bunch of metal to build the rotating frame out of. Keep all the electronics (including battery) as part of the mobile assembly, Run a long extension cord. Use a free-rotation extension cord if you can. Good luck, the project is pretty easy but will require some bumbling around with the code and the welding. (The reason you do a full sweep at wakeup/startup is to avoid accidentally tracking local maxima such as a reflection from a window or someone's driveway light. With algorithms, sometimes dumber is better.)

Bearing in mind the system is gravity fed if you plan on using a horizontal test bed. I want to see your motors make something fly!

[@Yaivenov]

This would work. It is done in real rockets too where there is no bladder/liner inside the propellant tank to keep pressurant separated from propellant. It just adds the requirement for ullaging to settle the propellant in the tanks. Apollo did this using the smaller rcs engines to apply a little forward thrust, the bipropellants for the AJ10-137 thus settled to the bottom of the tank. So yeah, omitting the syringe and pressurizing the perozide container directly should work just fine.

Not a bad idea. Even just having a water section after the hydrogen peroxide/steam nozzle that the pressure built up forces the water out. Having the heavier mass be thrusted backwards will give a much higher impulse.

@@Mr.Paulo. that’s the thing gasses do not care about moister. Just look at when a propane vessel is on fire. No amount of water will put it out.

[@Mr.Paulo.]

@@justinmolina4557 never thought about that, so he can just mix the engine's oxygen output with some propane and make basically a flamethrower? That's some freaking cool idea to try out

[@justinmolina4557]

@@Mr.Paulo. my thought is that it would be a really high pressure exhaust. If he can contain the force it would be a a serious rocket.

This is so awesome. You should totallu try making a radial engine using similar ingredients as your turbo jet engine. I want to attempt to make my own jet engine in the future. Your videos have been a great resource!

[@TheDIYScienceGuy]

Great video as always!!! I'm wondering, with all that oxygen in the exhaust, could it be used directly to power a hybrid rocket like you made in other videos? Or maybe an afterburner?

[@alexiaaddictiv-ink1898]

At this rate, I'm thinking you will have a running rocket suit prototype by next year this time 😉 Love your dedication. Keep up the good work.

Catalyzer sounds like a serum that some evil genius (named, ohhh, I dunno, Integza) developed to turn people into cats. Maybe that should your next video: developing the catalyzer.

[@simonstastny9097]

Project Idea: Maybe try to make a "professional" water rocket before building a chemical one, something that would fly hundreds of meters, you could even test it with an aerospike nozzle (or hydrospike?)!. I think it would help you develop the final version of a chemical rocket.

I wouldn't recommend using plastic gloves when burning things, if a hot flame or a drop of hot liquid, in fact, if anything hot reaches your gloves, the latex will melt and you'll have a great tale to tell when you go camping with your friends and family. Other than that, great video as always.

[@galestaffsylleianor3215]

Why not try printing a gas powered nozzle capable of accelerating air through the speed of sound, you could then combine such a nozzle with most of your other rocket or jet exhaust allowing you to greatly increase the exit velocity and so improve the amount of thrust produced. A way to do this would be to take a compressor fan/centrifugal fan like the one you used for the afterburner and use it in much the same way as in that video to produce a stream of higher pressure air, then pass this into a sufficiently converging nozzle, this will take you up to the speed of sound. The harder part is then to get the diverging nozzle on the other side to expand at the correct rate leading to supersonic flow through the bell, and then maybe some nice images of some mach diamonds out the back.

[@sergeykuznetsov3692]

The idea is good, but it wouldn't work with any commercial EDF and most DIY centrifugal fans cause De-Laval nozzles start working at pressure ratios of at least 2.5 (Chamber Pressure / Ambient Pressure), but EDF's can't go beyond 0.1 atm overpressure. To get the required pressure ratio you would need a multistage axial compressor like in a real turbo-jet engine.

[@m.sierra5258]

Idea is good, but first the chamber / plumbing has to stop blowing up :D I think you are skipping ahead here

[@minklmank]

Nice - you basically built a H2O2 based monopropellant rocket engine! Though your thrust in this design is capped by your maximum chamber pressure, which is limited by your maximum injection pressure which in this case is 4 bar due to your "fuel pump" design - which if i recall correctly has been used in the past by I think soviet rockets. (top of the tank as a piston head to pressurize the fuel above using pressurized gas as a driving force). A very simple and elegant solution. With your Ethanol / H2O2 / Permanganate experiments you by the way almost had a replica of a WW2 German V2 Rocket engine. Using H2O2 via Permanganate catalyst to drive a turbo pump that feeds an Ethanol / Water mixture and Liquid Oxygen into the chamber of the engine (water was added to reduce exhaust temperature because of problems with nozzle disintegration)

Video idea : now that you have mastered the art of devil's toothpaste, you can build a canon out of it. Quite the same setup as this video except that the chamber is standing still while shooting something ! (Like tomatoes for example 😈)

[@ATINKERER]

You really are brilliant! The idea for impregnating the ceramic was a great idea. I was thinking of using the inside of a car's catalytic converter. The platinum film they coat the converter part with will work with the H2O2, and it will never wear out.

[@CodockDraconin]

Maybe find a slightly slower, steady reaction to produce the steam and use the steam to run a Tesla turbine powering a propeller. If you can make a light enough high pressure catalyst container, you may be able to get a longer running engine than just the short blast rocket engine.

[@patrickstarbed]

Wow, this really shows how powerful Devil's toothpaste is, even at such a small level. Lots of respect to both of you!

I remember when I was younger, I was consistently rinsing an item in hydrogen peroxide. I eventually set out a dish of hydrogen peroxide which I would drop the item into then retrieve it and use the same dish of hydrogen peroxide later. As young kids do, I forgot about it and went several days without using that bowl. When I finally used it again, it immediately burned (not flammably) the skin on my fingertips. The only logical assumption is that water evaporated and increased the concentration of the hydrogen peroxide. Why not try slowly evaporating hydrogen peroxide or using low heat to distill water off of it?

[@abhimaanmayadam5713]

By that point, the peroxide should have decomposed into water.
