Headscratcher question of the day

Now don't laugh I barely remember what little I learned in my high school and college chemistry classes and I'm feeling punchy because I didn't eat breakfast

It's not possible to take the oxygen out of water? right? because that would leave only the hydrogen right?

A patron is asking me how to do it. really.

You can do it with electrolysis, I think. Basically, you pass a certain sort of electric current through water, and it breaks down the molecule and turns it into the component oxygen and hydrogen. It's not a very efficient process at the moment, though, which is why hydrogen isn't as abundant a fuel as people sometimes think.

The lazy student's friend has details.

It's an energy intensive process. As you might expect, considering that the reverse generates energy.

one's friendly librarian knows all things, of course...

Do you get calls for medical advice, too? ;-)
