tajuton

Tajuton is a fictional material described in science fiction and world-building contexts as a high-density energy storage medium. In common depictions, tajuton is a crystalline lattice of a hypothetical element or compound capable of reversibly storing large amounts of energy with minimal degradation over many cycles.

The term tajuton was coined by writers and enthusiasts in modern science fiction and online world-building communities. There is no universal origin or real-world counterpart, and different settings tie tajuton to different geographic or planetary sources.

Physically, tajuton is portrayed as a robust, temperature-stable material with high energy density and fast charge-discharge characteristics. Descriptions vary but often include forms such as pellets, sheets, or composites, and the lattice is said to accommodate tunable properties through doping.

In-world geology and industry describe tajuton forming under high-pressure metamorphic conditions in specific regions or planets. It is mined as an ore and processed through annealing and doping to optimize performance, with purification addressing impurities that affect energy release.

Applications in fiction include spacecraft power systems, urban energy grids in advanced civilizations, and portable devices. Tajuton is frequently used as a plot device to explore resource scarcity, geopolitical competition, and technological frontier-pacing.
