Releul
Releul is a fictional term used in speculative design and science fiction to denote a class of hypothetical energy-harvesting devices. In the concept, releuls are compact modules that interface with ambient energy fields—thermal gradients, electromagnetic radiation, and mechanical vibrations—and convert fluctuations into usable electricity through a resonant lattice architecture. A key feature is a self-regulating feedback mechanism intended to maintain stable output without active control.
Design and operation: A releul lattice consists of repeating resonator units arranged to form a meta-material-like
Origins and usage: The term appears in speculative fiction and design essays in recent decades, where it
