'''Hydrogen''' has the [[atomic symbol]] H and the [[atomic number]] of 1. Hydrogen is the most abundant of all the chemical elements, the [[universe]] is composed of roughly 75% hydrogen. However naturally occuring elemental hydrogen on [[Earth]] is extremely rare.

The hydrogen [[fuel cell]] is a pioneering form of alternative energy. It is very clean burning, the only by-product of its combustion is pure [[water]]. This would slow down the impact that [[global warming]] is having on the Earth. Unfortunatlly there are some set backs. The amount of hydrogen needed to fuel a regular sized car would be extremely large and would not be as convenient as a fuel tank is now. Hydrogen is extremely [[flammable]] and the flame is nearly invisible. The chances of a massive fatal explosion in an accident is greater than in one with [[gas]] powered veichles.

If hydrogen could be used in cars, it would be important in establishing the [[hydrogen economy]].
