What? I'm sorry but thats incorrect. I'm guessing you found this out from this site [url:3691f]http://www.motherjones.com/news/outfront/2003/05/ma_375_01.html[/url:3691f].

[quote:3691f]Hydrogen is natrually occurring. It can also be manufactured by running an electrical current through wateror by micing natural gas with steam.[/quote:3691f]
Water = H2O / Two Hyrdogren Molecules and One Oxygen Molecule. However hyrdogren can be found in fossil fuels but not specifically and it's much more difficult to extract.
Also extracting from Fossile Fuels is idiotic in the first place, while it may prove to be cheaper it :

I'd post more but I'm busy with a paper. Google Hydrogen and read up on it. I find this kinda shit fascinating. oOo:
Edit: To Coleman
Why would water be a bad idea if not seawater? If you think were running out of water your mistaken. Plus seawater would cost more to purify and extract the hyrdrogen from.
