Making water with hydrogen.

It is no secret that water is a combination of one part hydrogen to two parts oxygen. if we could gel these, they would provide a lot of water in plentiful amounts, yes?

This means that merely heating hydrogen will make it bond with oxygen! we could have a heated area where the hydrogen bonds with water, and then returns via gravity to the earth or dam through bonding with other gases.

If we were to heat oxygen, the same would happen. this means, basically, we just need to heat the air and receive the water we want, as fresh as can be. this can easily be done in rural areas by having a steel pole or other metal, high above a bucket, with electricity running through it.

So, we would have a electrically charged metal pole or grid of fencing being heated by the electricity running through it. this can be done without charge, through having a lot of metal grids laid upon each other underneath and above two glass panes to insulate the metal. this could be better served by having it lie at an angle and having the water go into 'the bucket.'

Of course, the mechanism could be boosted by instead of having wire instead having a pane of metal, that will heat up under the sun and provide water on the other side of the glass. the more of these metal and glass panes you have, the more water you will generate.

Then, you could also purify water by placing it on top of the glass panes or the metal pane.

 

What is the point of this error filled post?

H20 is composed of two HYDROGEN atoms to one Oxygen atom. You got it backwards.

 

There is virtually no "free" (uncombined) hydrogen floating around in the air, and what little there is is so dispersed that no appreciable amount of water would be produced.
Read a chemistry book and stop embarrassing yourself.

 

You are correct, but probably the least of the errors in that post.

 

Too soon for post of the month nomination?

 

You are correct. However, the atmosphere only contains about 0.000053 hydrogen (78% Nitrogen, and 20.95% Oxygen).

 

About 71% of the earth is covered in water. The problem is not a lack of water. The problem is getting fresh water where it is needed. But I forgive the OP. He is young and I think he tries real hard. If he gets a good education and some real life experience he may go far.

 

You know, they have these devices called "water cubes" that are capable of extracting water from the air around it. Another one is solar powered and heats the water into steam, and then condenses the steam back into pure water.

Either one is now readily available for 1,000 bucks to 9,000, and would be more efficient and work faster and better than what the OP is suggesting as a "plan".

Matter of fact, was watching a documentary one time where they built a large dome kind of enclosure somewhere in Africa, and then put netting all around it and that device was capable of getting water out of the air.

 

Actually, O2 is not water.

 

I never said that 02 was water.
I said "You are correct. However, the atmosphere only contains about 0.000053 hydrogen (78% Nitrogen, and 20.95% Oxygen)."

The parenthesis weren't meant to modify hydrogen, it was just extra information to put the 0.00053% (forgot the %) Hydrogen in perspective. The point is that while his idea would work, the problem is that there isn't nearly enough hydrogen to make it practical.

 

Yes, getting fresh, uncontaminated water is becoming a challenge.

It seems that politics is making that challenge worse as leadership is increasingly appointed by corporate money corrupting elections.

Unlawful politics need to be stopped. Hard to understand why any would participate rather than justifiably unifying with other state Citizens under the law to purify the politics.

You know, even here in Amarillo there is a problem with the public water supply on occasion. Once in a while, if you draw a glass of water from the tap, there are white little floating things in it. Kinda looks a little like a snow globe. Matter of fact, a year or so ago, my roomie and I started to get water from the local tea and water place, because if you drink the tapwater on an empty stomach, on occasion, it will make your stomach ache.

I've got a feeling, that one day soon, everyone is going to HAVE to have some kind of filtration system on their taps.

 

EGAD! I'd get that water tested! It could be very dangerous to drink little white bit that you can't identify. It may just be calcium deposits but it also may be lead or other substance. I wouldn't touch it!!

 

No, he is not correct.

1) As has been said, water is TWO parts hydrogen and ONE part oxygen.

2) To combine hydrogen and oxygen the two must either be combined by burning the hydrogen with oxygen, or combined by means of a catalyst.

3) Heating air will not produce water. Rather, it will actually increase the amount of water that the air can hold as vapor.

4) Heating a metal or other surface ("pole" or "fencing" for example) will dry the surface of all water that may be on it.


I think this is like the little boy whose 3rd grade class was being taught sex education and who went home and announced to mommy that he and Suzie had planted some watermelon seeds down the road by the telephone pole "so they could have a baby next year".

 

If you were to heat the air, like in summer, there would be water vapour collecting and hopefully rain too.

 

Take a course in physical chemistry. According to your theory, if you put dry clothes in your clothes "dryer" and run it, your clothes will come out wet. I thought everyone knew that heated air holds more water than cooler air. And that means that as you heat air, the relative humidity falls, --it gets "drier" and can hold more moisture. If you want moisture to condense out of humid air, cool the air. Did you ever notice that unlike in summer, in winter your breath condenses on glass? Put a mirror in the fridge and put another one in the oven. Heat the one in the oven so it's warm but you can hold it. Take them both out and breathe on them and tell me what happens.

 

Have you observed the water cycle? this is where the sun shines onto the water - like heat? - and then the water vapour comes inland with the wind. when you observe a freezer, i would say it is the air becoming ice out of the air, yes?

If you stick metal in a furnace you will be able to 'melt' them into... something else. this metal will give off steam, which will become something like 'acid rain,' yes?

 

A reverse of what the OP suggested ie obtaining Hydrogen from water to use as fuel is a much more worthwhile topic. Whilst much of the technology is available already I don't fully understand the reasons it is not being more enthusiastically pursued.

 

I have a degree in chemistry with studies in physical chemistry and physics. You have much to learn, most of which will entail unlearning mistaken ideas.

 

Perhaps you can help me with my knowledge gap about extracting hydrogen from water then?

 

Several reasons. First, there is an energy loss in the conversion of water to hydrogen and oxygen. Second, hydrogen is one of the least energy dense fuels. Third, because of energy density, we have to either have high pressure hydrogen (at least 5000 PSI tanks), or go to elaborate means to store the hydrogen (which is another energy loss). Also, the cheapest way to get hydrogen is from natural gas. It's probably better just to burn the natural gas.

 

Pose a question. What do you want to know?

 

Thank you. I understand the energy loss but if clean sources could be used this could be mitigated.
The energy density problems and the safety concerns with pressurising it I have a little understanding of but considering the possible sustainability are there really no practical applications?

 

In the case of production from natural gas, the process is 80% efficient, and that is one of the highest efficiencies for hydrogen production. But for every ton of hydrogen it produces, 3 tons of CO2 are also produced. So the process requires more energy than it yields, and it produces more greenhouse gas.

Production from electrolysis of water is much less efficient but it can be done using solar energy and it yields hydrogen and oxygen. But still, since production of hydrogen requires more energy than is available from the hydrogen produced, the use of hydrogen is usually limited to cases in which hydrogen is exceptionally convenient as a fuel.

 

My understanding of the chemistry is that, disregarding the dirty energy used to produce the hydrogen, using it to power a car for example could be a water in water out solution to pollution and sustainability. Is it an issue that the water vapour produced has a powerful greenhouse effect?
