Voltida

Voltida is a term used in speculative fiction and worldbuilding to describe either a unit of electrical energy, a storage medium, or a digital currency within future economies. Unlike established SI units, voltida has no formal definition or standard symbol in real-world science, and its meaning varies by work.

Etymology: It combines volt, the SI unit of electric potential, with the -ida suffix sometimes used to name fictional measures or entities, signaling energy or value.

Usage in fiction: In some narratives voltida refers to a crystalline energy store powering starships or cities, often described as a lattice that can be charged and transferred. In other settings, voltida serves as a decentralized digital currency or credit in interplanetary trade, linked to energy production or storage capacity rather than fiat reserves.

Real-world status: The term appears in fan wikis, worldbuilding forums, and some science fiction glossaries, but it is not standardized and has no official measurement or unit equivalence. Engineers and historians generally treat voltida as a fictional construct rather than a physical quantity.

Notes: The usage is highly variable; readers should consult the specific work for its definition.
