pulgad

Pulgad is a term used in speculative technology to denote a modular, autonomous energy-management system designed to operate within microgrids. Each pulgad unit is a compact device that integrates sensing, computation, storage, and switching, and they coordinate via a peer-to-peer protocol that tolerates node failures. The system is designed to perform local optimization of generation and demand, reducing reliance on centralized control.

Origin and concept: The term emerged in collaborative worldbuilding and science fiction glossaries in the early 2010s and has since been adopted in educational simulations and hobbyist wikis. The concept draws on real-world ideas of microgrids and distributed control but remains hypothetical.

Design features: Pulgad units are modular and scalable, enabling networks to grow by adding more units. They incorporate self-healing mechanisms, local weather and load forecasting, and simple energy-token economics to encourage efficient sharing of resources. Security considerations emphasize lightweight cryptography, tamper-evident logs, and auditable decision histories.

Applications and usage: In imagined settings, pulgad networks support power delivery for remote settlements, field research camps, and post-disaster relief operations. They are also used in classroom simulations to teach distributed systems, energy economics, and resilience.

Reception and critique: Proponents argue pulgad illustrates how distributed autonomy can improve resilience. Critics note its fantasy status, potential over-optimism about hardware capabilities, and the gap between fictional models and current technology.
