Tylium

Tylium is a yellow/black fantasy fuel obtained from Tylimite.

It is a fuel.

Tylium is from Glen A. Larson's science fiction movie; Battlestar Galactica. Tylium ore is rendered inert and unusable when exposed to nuclear radiation. Refined tylium precursor is more unstable and much easier to ignite than the finished fuel itself. A tylium detonation results in no radioactive fallout.
