luvua
Luvua is a fictional mineral used in speculative fiction to describe a high-density energy storage material. It is not a real substance, and its properties vary across works, but it is commonly depicted as a crystalline, luminescent ore with the capability to store and release large amounts of energy with minimal loss.
In many narratives, luvua can absorb ambient energy—such as solar or geothermal power—and discharge it on demand
Geography and economy: Luvua deposits are typically described as occurring on tectonically active planets or moons.
Variants and usage: Some stories describe lightweight or high-stability luvua variants with fewer risks, while others
