starsor

Starsor is a term used in speculative contexts to describe a hypothetical energy-harvesting technology or process that draws power from starlight. The word is a combination of star and sorb, reflecting the idea of absorbing radiant energy. In fiction and worldbuilding, starsors are imagined as highly efficient collectors—ranging from nano-scale metasurfaces to large orbital arrays—that capture photons and convert them to usable energy or store it for later use.

There are two common design ideas associated with starsor concepts: a direct conversion device that converts light into electricity with minimal loss, and a staged system that channels captured energy into storage or propulsion technologies. Some interpretations envision networks of collectors distributed across spacecraft, habitats, or planetary systems to enable long-duration operations without conventional fuel.

In real science, starsor remains speculative and not supported by empirical evidence. Challenges include thermodynamic limits, material durability, and the practical efficiency required to justify the energy costs of collection and conversion. The concept is often used in worldbuilding to explore sustainable power for spacefaring civilizations, deep-space missions, or off-world colonies.

Though popular in science fiction and gaming lore, starsor is not a recognized term in contemporary astronomy or engineering. It serves as a thought experiment about how civilizations might harvest stellar energy under extreme conditions. See also solar energy, energy harvesting, metasurfaces, Dyson sphere.
