What would that do to greenhouse gases and global warming?If we converted (for example) 1% of the ocean to hydrogen, oxygen, salts, etc. Would air pressure increase? Or would the atmosphere simply expand?
Edit: Since everyone's confused about how I'd power it, I'd use solar power. Solar panels can easily output 1.5v today.
To address your hypothetical though... Both would happen. Air pressure is just the weight of the atmosphere above you. If you add more gas to the atmosphere, it would indeed get 'bigger', and would therefore weigh more, resulting in higher air pressure.
What?? The amount of hydrogen released is equal to 82% of the electricity input. Why are you saying "so little electricity"? If you have "so little electricity" you also have "so little hydrogen".
Did you and everyone think I was proposing to use gigawatts and electrolyse 1% of ocean water in a few seconds? O_o

I don't follow. What does voltage have to do with anything?

Um, yes. Do you have the slightest idea how much energy it would take to electrolyze 1% of the ocean? I did some math for you: you need 1.752×10^26 joules. If you had a gigawatt available to you it would take 5,552,000,000 years.
In this case energy is what counts not voltage.
It's powered by electricity. Where are you getting that electricity from?
Yes, this is a thought experiment.
Were you seriously concerned that I had a solution for rising ocean levels?
If you actually did this you would increase the atmosphere to 10 times it's current size - and most of that would be oxygen, unlike the current mostly nitrogen. Most of which would probably escape to space.
You'd have to find something to do with the hydrogen though, if you released it it would just recombine with the oxygen and make water again.
