What? I'm sorry but thats incorrect. I'm guessing you found this out from this site [url:88312]http://www.motherjones.com/news/outfront/2003/05/ma_375_01.html[/url:88312].

[quote:88312]Hydrogen is natrually occurring. It can also be manufactured by running an electrical current through wateror by micing natural gas with steam.[/quote:88312]
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.[/quote:88312]
What Ninty is saying is that Pure Hydrogen is not found on Earth. Hydrogen mixed with other things is, but you have to use something to extract it, which will require energy. Where do you think the electricity is generated to manufacture the hydrogen is coming from?
On topic: I'd work on making America itself more secure and begining setting up the infrastructure to switch to alternative fuels (when a practical one is available at least)
