yup u can use oxygen tanks as oxidizers and gasoline ....it is used for amateur orbital liquid rocket engines ........atleasr I'm using it in the rocket I'm building!!!

iquifying hho is a bad idea, it's technicaly an explosive, it's "safer" to liquify hydrogen and oxygen in two diferent tanks with two compressors

If you can tell me how to liquefy
hydrogen Ill be happy. I make about 1 Liter per minute(LPM) of DI hydrogen mon oxygen. Commonly known as HHO. Im interested in making a gas powered rocket.

Dihydrogenmonoxide is commonly known as water

. And you don't get monatomic Oxygen when you electrolyze (or any other process I can think of), anyway. Or was I asleep that day in Chem class? . Cool video, though.

OK you're not just posting junk - I appreciate the reply.

Where has anyone mentioned "Hydrogen MONoxide and the toxicity of Hydrogen Peroxide" on this thread (not in your previous comment)
And to reiterate my previous question (which you haven't answered):
What do you mean by So many of you are confusing HYDRAZINE (very toxic) with Hydrogen Peroxide?
The only person (apart from you) to have mentioned hydrazine is me, and I've not confused it.

i used to have hydrogen peroxide and theres barely any hydrogen but if you could make hydrogen gas and turnit into a liquid that would be nice

Wow. Chillax lemonie. A word of the wise, I don't care how smart you are, when you get incredibly defensive, people start to ask "I wonder why that guy is so defenisve...there must be a reason...hmmmm," even if there really is no reason at all. Please just relax as the answering of your question is pointless. (I know this was 2 months ago, but I thought it is advice you should consider at any time.)

just gasoline wont do, to maximise power it must be somewhat contained and containd means minimal air, therefore gasoline wont light it needs the oxidizer. one form of liquid-like rocket feul [explained in october sky] is mixing potassium nitrate KNO3 and pure alcohol [AKA Moonshine] and this was used for small scale rockets. unfortunately my teenage ignorance hinders my knowing ratios of KNO3 and alcohol or the chemical energy stored in the final product. *sad face*

To power space shuttles they use liquid hydrogen. To oxidize the hydrogen in a vacuum they use liquid hydrogen. And the SRBs are powered by atomized aluminum powder, which is oxidized by ammonium perchlorate with a bit of iron oxide mixed in.

use:oil,fome peanuts,some soda and a mentos in everything and now you have liquid rocket fuel.

you can use gasoline and a 50% hydrogen peroxide solution for oxidizer.  go to this web site for plans:

Hi, i have made and experimented with a couple home/workshop built liquid fuel motors. I used a system of keosene/aircraft fuel, pumped oxygen and a blast of nitro on one model. out of all 12 experiments, only one made it off the ground. The rest exploded, mainly because of the fuel sources being mounted above the engines (its a rocket, so i had no choice but to install them there). The system is fairly safe on a test stand. Im going to build another proto during april and ill get the video up. The hydrogen/liquid fuel method is very hard to make the fuel and also the engines are not very affective (and when they are, they have a tendancy to overheat causing fire/explosion). but this depends on your designs, facilities to cast the components or locate components and how much you are putting into your project. Also last word of warning; most liquid fuel engines/fuel storage is very heavy, so you must think of extra risk factors like; size, parachute, failsafes and propulsion. if one of these aspects are over looked or not followed, you could possibly cause alot of damage and possibly kill someone.

their are many propellents one of them that i might use is kerosene and alchohol, hydrogen and liquid oxygen is another but i dont recommend that, the basics of liquid propellent is that their are two parts to it fist is the oxidizer wich helps ignite and combust second is the fuel wich helps that flame keep going. see alchohol is realy flammble if their is a high percentage of it , which makes it the oxidizer , next is the kerosene which can last a very long time so that makes it the fuel. you can also have a liquid oxidizer and a solid fuel(which is much safer) so now all i have to say now is be safe and goodluck

Binary liquid fuels? Yes, but you'd have a job getting both liquid components, and you shouldn't try it either.

How about water rocket tech only the liquid is a flammable one, air pushes on the liquid through an atomizer which has a heat source that ignites the liquid through a nozzle . If it's not good enough then I'll think of something. Simple though, I think, no idea where to get atomizer, maybe a narrow hole will do to make a line that will ignite in a nozzle .

You could do that with a can of butane, but you wouldn't get enough thrust out of it. Chemical-fuel rockets use high energy density fuels and oxidisers. Some examples: Hydrazine hydrate (nasty) / concentrated hydrogen peroxide (dangerous) Hydrazine hydrate (nasty) / concentrated nitric acid (dangerous) Kerosene / liquid oxygen (very dangerous) Liquid hydrogen (very dangerous) / liquid oxygen (very dangerous) L

One aspect of liquid-fueled rockets I have not seen here is the immediacy of launch when using liquefied propellants. Generally, when using a liquid fuel for rockets, the vehicles cannot be stored with fuel. Additionally, most backyard rocketry hobbyists are not equipped to perform nitrogen or argon purges of their propellant tanks after test fueling their bird. The "best" liquid fuels for hobbyists are those that are relatively stable at room temperature and have reasonably high flash points. Gasoline, for example, is a much safer fuel than methyl ethyl ketone. For nozzles for liquid-fueled rockets, are generally made from less-reactive materials than solid-fueled rockets. This is because you generally want to recover and reuse liquid-fueled rockets. Liquefied gases (such as liquid oxygen) can generally be purchased by anyone over 21 from companies who specialize in LOX and dry ice. Prior to building or launching any rocket, check your local, state and federal laws regarding model rocketry.

Acetone peroxide (TCAP) is to unstable for rocket, not to mention it's something the average American shouldn't be doing. Though hydrogen peroxide and mangenese dioxide react and this is sometimes used for rocket fuel. But they use upwards of 90% hydrogen peroxide.

Heh. Back when I was a kid, and a chemistry buff, and a space nut, I made up these "plans" for a rocket that dripped peroxide on MnO2 to create the oxygen that I had read was needed. I just had no concept of the sort of mass flow involved... (Hey, we're talking like 8 years old, in 1967 or so!)

it was a paper design; I think I planned to use ordinary drug-store (3%) peroxide. It never would have worked at all, even if I had built it. It was right up there with the solid fuel rocket I made, after being warned about fine-powder explosions by my dad ("nearly anything will burn if finely enough powdered. Grain silos explode periodically") by packing some copper pipe with powdered chalk...

get concentrated rubbing alcohol and liquid oxygen, compress them in two different tanks and release and mix the two in a combustion chamber and then have a nozzle direct the gases out
remember to use check valves and flame arrestors so the gases don't mix and ignite inside the pressurized fuel tanks
if you mix the two into one single tank and expect it to work, you will die in a horrible explosion

I get it with the alcohol, but you could use other fuels. Liquid oxygen boils at -183'C and as such requires specialised storage and transport: not easy to get hold of (unfortunately).

LOX is actually pretty easy to obtain. Sorta scary. Liquids can't be compressed, though, and LOX has a habit of boiling at room temperature, so it's not quite so simple. If you're interested in making rocket motors, the "next step" up from solid fuel is probably a "hybrid motor" using nitrous oxide as the oxidizer. There have even been successful "tri-bird" motors that start as a Nitrous/solid hybrid and then inject alcohol for liquid-fuel operation. Unlike lox, nitrous "self-pressurizes" to reasonable levels (~700psi)
