Are there any possible ways to do that for mass production?Is it hapenning allready?

By itself, water is an unreactive substance by nature. So you cannot separate oxygen and hydrogen from the water molecules. However, there is only one ay in hich this canbe done: electrolysis.
It involves the passage of an electric current into a liquid, which naturally conducts electricity. Electrodes are used to pass the electric current. At both the electrodes, gases are evolved, depending upon the liquid.
Some acid or alkali should be added to water for the evolution of gases, namely hydogen and oxygen at the electrodes.
It can be mass-produced, but the process is too costly. An application could be to use hydrogen in hydrogen powered cars to replace the more polluting petrol powered cars.
Moreover, oxygen is also obtained by the fractional distillation of liquid air. It involves cooling air by decreasing the its pressure by placing them in special containers, capable of bearing atmospheric pressure. This process is more economical, compared to electrolysis. Liquid oxygen and hydrogen is used to power rockets in order to propel them into space. This process for the production of liquid oxygen and hydrogen is mass produced nowadays to power rocket and hydrogen powered cars.
Thanks

Absolutely. It's called electrolysis of water. You put electricity in on two electrodes and separate water into oxygen gas and hydrogen gas in separate chambers. Unfortunately, it won't solve any problems because it takes every bit as much energy input to do this as what you can get back out. The Law of Conservation of Energy sucks that way.

Has to be done by electrolysis, where hydrogen is reduced at the cathode and oxygen oxidized at the anode in an electrolytic cell.

Yes,we can seperate oxygen from hydrogen by the method of electrolosys.Just pass electricity in it.

sure we can; electrolysis BUT DON'T DO IT
It's dangerous as in EXLPOSION dangerouspur hydrogen is not good for us
ANd of course it's happening today n large numbers, in factm, some countries depend on the elstrolyisi of water.... Hyroelectricity... it isn't called that for no good reason u know

Sure, you just pass an electric current through it.
the problem is, it uses a lot of energy, much more than you would get by using the hydrogen for power.

It can by using electrolysis. I don't know why you would unless your looking how to make a hydrogen powered car.

electrolysis will do it, but in the long run it's expensive. i've done it a few times. H2 makes a nice pop when you burn it.

yeah- pass a current through it and you get:
2(H20)---> 2H2 + O2
It's called electrolysis
