Radiuser

Radiuser is a term that appears primarily in speculative contexts rather than as a formal scientific term. It refers to a person or device that uses radiation to generate, manipulate, or sense energy. The word combines radi- from radiation with -user, indicating agency or function. It is not a standard scientific term; its meaning varies by author or designer.

In fiction and game design, radiusers may be depicted as individuals who can emit, channel, or control electromagnetic radiation, or as engineers who operate devices that harvest or redirect light and heat. Powers or technologies attributed to radiusers range from energy projection and cloaking via light modulation to solar-energy harvesting and radiative cooling systems integrated into suits or tools.

In real-world science, there are related but distinct concepts: radiation detectors, photonic devices, solar cells, and thermophotovoltaic systems. These technologies involve coupling or converting radiant energy but are described with more specific terms rather than "radiuser." The term itself remains informal and context-dependent, often used to illustrate a character concept or a hypothetical device in speculative writing or early-stage design documents, rather than a recognized field.
