What's with this "hydrogen fuel" craze? I heard something on the news about Iceland wanting to become entirely hydrogen powered. The reason being about reducing dependency on foreign oil. Can anybody explain to me how this would reduce dependency on oil? Hydrogen gas is made from methane; the reaction is called the "water gas shift reaction" if you want to look it up. Methane, aka natural gas, is just as limited as oil. How does it benefit a country to switch over from limited resource A to limited resource B, if your country has neither A nor B, and resources A and B are both owned by the same group of people (middle east).
