Can you burn water and make energy using a electrolyzer then burning the oxygen and hydrogen.?

Question

Can you pull the hydrogen and oxygen out of water with a electrolyzer and then burn hydrogen and oxygen in a generator to make electric that would then run the electrolyzer? In doing this could you generate more electric than you need to run the electrolyzer? Making power from water alone. Please before you say that you can't make more energy than you put in. Please think about what you are doing. The energy you are putting in is only to brake the hydrogen and oxygen out of the water. If hydrogen can be ran in a generator that would use propane and run at the same cu ft/hr as propane you can generate more power than it takes to run the electrolyzer. The oxygen is not even being used at this point and if you could use a generator that could use both the hydrogen and oxygen you could make even more power.

A little bit of info to help 9000w of electricity can produce 70 cu ft/hr of hydrogen. 64 cu ft/hr hydrogen can produce 12500w of power in a normal 4 cyl generator.

Answer 1

Yes it is possible!
To begin with lets start this way. Energy can neither be created nor destroyed , but can only be transformed from one form to another
And the universe started from Nothing.
nothing = anti matter + matter
what we experience is matter. That does not give us the right to deny the presence of antimatter. So logically energy can be created from nothing if we seperate the negative out of positive. A molecule is nothing but when seperated into atoms and ions its a lot of energy. And thinking that you need more energy to do this than you can gain is insufficient knowledge!

Answer 2

Chemical potentials work just like gravitational potentials. If you have water at high elevations, its potential energy can be harnessed as it drops to lower elevations. But once it's at the lower elevations, unless it has a lower place to go, no further energy can profitably be wrung from the water hydraulically. Likewise, the chemical bond between hydrogen and oxygen is already at a very low place, so that you'd have to react it with something like pure metallic sodium to wring any more energy out of it. Propane won't do, even if you did use up energy to split the water and then using the oxygen to burn the propane. You won't win this one, because propane won't yield enough energy to make this work. This has already been thoroughly studied by chemists for the past couple hundred years.

Answer 3

No, Electrolysis is not very efficient in terms of potential energy created (in hydrogen).

Say you have some amount of energy, say 1000 watts. If you used it all in electrolysis of the water, you would get an amount of hydrogen that, given the most efficient engine, would only produce 300 watts of power to put back into electrolyzing more water. Not because the hydrogen engine wasn't very efficient (though less then 100%) but because the hydrogen produced was not very much for the amount of energy invested

Answer 4

Well, I'm going to say it anyway: You can't make more energy than you put in.

Sorry, but you can't - the energy that you are using to break down the H-O bonds is EXACTLY as much as you will get when you put the bonds back together. In a perfect system, one where no energy is lost by heat transfer to the outside environment, container walls, electrolysis device, et cetera, then you will have a net energy gain of zero.

And the oxygen IS being used - when you burn the hydrogen. Burning hydrogen requires oxygen, it's a fact of the equation.

Answer 5

You could separate hydrogen and oxygen, then burn them, Yes.
But you can never beat the laws of thermodynamics.

Simply put -
Law 1 - you cannot win in this game.
Law 2 - you cannot break even in this game.
Law 3 - you cannot get out of this game.

Answer 6

Won't work. The energy required to break the bonds in water equals the energy released when the elements recombine -- reduced by losses in the process.

Answer 7

There is a rule that u cannot make a perpetual motion machine. Every transition of the energy will cost u more than u can make.

Answer 8

You can do this, but you'll spend more enegy powering the process that you'll get from it.
