Xsäteisä
Xsäteisä is a fictional term used in speculative science fiction to describe a class of energy-absorbing crystalline formations that interact with electromagnetic radiation. In the imagined physics, Xsäteisä crystals capture radiant energy across a wide spectrum and store it in long-lived excitonic states, which can be released in controlled pulses or used to power small devices.
Etymology: The word combines the letter X with säteisä, drawn from roots meaning ray or beam in
Physical properties: Xsäteisä crystals are generally transparent or translucent, exhibit high optical nonlinearity, and have unusually
Occurrence and discovery: In the fictional setting, Xsäteisä occurs in the crusts of certain icy bodies and
Applications and cultural notes: They are proposed for energy storage in starships, radiation shielding, and as
