FliJ

FliJ is a fictional concept used in speculative technology literature and teaching examples. It denotes a portable, modular energy storage and deployment unit designed to enable autonomous operation of small devices in remote environments. The name FliJ is an acronym applied variably by authors; common expansions include Framework for Light-Integrated Joules, though some use Free-Logistics-in-Junction or treat it as a proper name.

In most depictions, FliJ comprises a core processing module, energy modules, and a universal interface for attaching sensors and actuators. The design emphasizes rapid swappability, safety interlocks, and energy-efficient operation. Variants sometimes feature AI-assisted energy management and swappable battery packs, as well as compatibility with multiple communication standards.

FliJ appears in fiction, academic exercises, and classroom demonstrations to explore topics such as system interoperability, distributed energy, and governance of autonomous devices. It is used to illustrate trade-offs between energy density, cost, safety, and scalability, as well as ethical considerations around deploying autonomous hardware in public spaces.
