 P: 136 Does anyone know how to take Water H2O and convert it to Hydrogen peroxide H2O2, so basally I want to add another oxygen molecule to the existing oxygen molecule? I want to use the Hydrogen peroxide for a fuel, cheap fuel, don’t want to buy petroleum products anymore and I care about the world also a bit.
 Emeritus Sci Advisor PF Gold P: 11,154 This is a completely useless quest. To use hydrogen peroxide as a fuel (monopropellant), you are essentially decomposing it into water and oxygen. You will get back no more than the enrgy you put in to make the peroxide out of water in the first place! And where are you going to get the energy to do that from? If you want to reduce consumption of petroleum products, consider renewable sources like solar or wind energy.
 P: 154 This might get a better response in the Chemistry forum... EDIT: no offense to the response above, it just wasn't there when I first posted. Also... nuclear power ftw! Damned nuclear protesters need to realise that THEY are the reason we are still pumping the poisonous remains of burned gas, coal and oil into the atmosphere. Probably no good for a car though... at least whilst protesters are busily crippling research efforts.

Water H2O convert to Hydrogen peroxide H2O2

Gokul43201, Will this be like to make hydrogen using huge amounts of electricity in the Electrolysis process.
So basically converting the energy into usable another form.
So if you know the process, you’re welcome to tell me.
The energy I’m going to get out of the mains if I understand you correct.

I’ve seen something like a hydrogen peroxide car and rockets and stuff.
 P: 2 Is there a way to calculate how much energy is required to convert a unit of water to hydrogen and oxygen. How much energy can be recovered from using that recovered hydrogen and oxygen in a fuel cell. and how feasible is it?
 P: 135 Electrolysis of water is going to require more energy than the combustion of the products, in essence the electrolysis should have equal energy in theory, but most electrolysis processes are around 50-70% efficient, and combustion of the products will not utilise the released thermal energy 100%, therefore its best just to use the electricity directly in an electric motor, rather than splitting it to use it in a combustion engine.
 P: 158 if you are using the heat then that isn't a problem. some fuel cells aren't very efficent. The minimum voltage to split water is around 1.5 volts. 1 gallon of water produces about 1300 gallons of H2\O2 gas.
 P: 1 It can be converted by using ultra violet rays, so if you have and ultra violet light of some sort. Or, if you live in an area with a large amount of sun then you would need something to filter out other light and only allow the ultra violet rays to hit the water, but make sure it is in a closed container, so that it does not evaporate.

I don't know in your country; here in italy you can buy sodium perborate or percarbonate in supermarkets; you mix it with water...voilà $$H_2O_2$$ (diluted).

If you want to find more concentrated $$H_2O_2$$ , up to ~ 35%, you can by it in an hardware shop.

You can also make it from $$BaO_2$$ and $$HCl$$, or by electrolysis of $$H_2SO_4$$.

As rocket propellant $$H_2O_2$$ should be highly cocentrated however (more than 70% according to wikipedia) and in that case it's very dangerous. Don't know how to concentrate it so much.
 P: 8 I actually was working on a method to produce hydrogen peroxide from water using moving magnetic fields. I took this project to the state and international science fair. Basically I borrowed from an austrian scientist Viktor Schauberger as well as some lone R&D russian researchers such as Voeikov...(no sure if that is spelled right), to make a device which generated a vortex in the presence of a very strong moving magnetic field. This spontaneously produced hydrogen peroxide in the water, not a lot, .05ppm peroxide. The fact is, it can be done, and I am currently working on a way to increase output. This project has met with ample resistance from the scientific community, but the results are there.

Possible pipe dream here but..

How about outback Australia (specifically the sparsely populated north west). Average daytime temperature in winter is around 28C. (http://www.bom.gov.au/climate/averag...w_004019.shtml) Plenty open arid land to build solar panels on/ ultra violet tanks/ wind farms. Close to the sea (supply of water). Capture it the hydrogen in tanks and ship it in bulk to population centres for sale as alternate fuel.

 P: 2 Try and do some good research at www.hydrogengenerator.com, You may even find me there, LtCFisher. Hydrogen Fuel Cells or Reactors are easy to make and can produce enough fuel to run your vehicle, heat your home, or even your lawn mower. That I do know, I produce 30 some Liters a minute from one single fuel cell.
 P: 6 thank you!!!

So you're powering a very strong magnetic field and moving it across the water, but only generating 50 parts per billion hydrogen peroxide? That's got to be a losing proposition.
