Hydrogen glows purple in its plasma state.

Hydrogen is the chemical element with atomic number 1. It is represented by the symbol H. With an atomic weight of 1.00794 u, hydrogen is the lightest and most abundant chemical element, constituting roughly 75 % of the Universe's elemental mass. Stars in the main sequence are mainly composed of hydrogen in its plasma state. Naturally occurring elemental hydrogen is relatively rare on Earth.

Hydrogen in "Getting Real"Edit

In Los Angeles in 2117, transportation within the city was primarily by foot, bicycle or pedicab. However, there were occasional hydrogen or electric-powered cars on the roads.

Hydrogen in Southern VictoryEdit

Shortly after the end of the Second Great War, captured Confederate physicist Henderson V. FitzBelmont shared the theoretical possibility of a hydrogen-based superbomb with U.S. Army General Abner Dowling. FitzBelmont shared the theory only because he knew that the U.S. was already building the theoretical "sunbomb". The possible destructive power such a weapon might inflict horrified Dowling.[1]

Hydrogen in The Two GeorgesEdit

For much of the history of airship travel, hydrogen was used for lighter-than-air buoyancy. However, it was eventually supplanted by the non-flammable coronium.[2]

Hydrogen in WorldwarEdit

The Race had made use of hydrogen as a fuel for their vehicles for millennia before they invaded Earth in 1942.[3] The Race was initially perplexed by Tosevites' decision to use petroleum for transportation, as they saw it as an utter waste of the resource.

After the Peace of Cairo, most of the oil-rich regions of Tosev 3 were under Race control. The free not-empires of the world soon adopted hydrogen as a fuel.[4]
