Diqu

Diqu is a fictional mineral that appears in science fiction literature, film, and worldbuilding projects. In these works, diqu is prized for its unusually high energy density and resilience, making it a central element of futuristic power systems and propulsion schemes. Because diqu is not a real substance, its properties and rules vary by author, but it is commonly treated as a naturally occurring crystalline energy store.

Physical properties: Diqu crystals are described as dense with a stable lattice that permits rapid energy release and recharge. They are typically depicted as inert at normal temperatures, with broad thermal tolerance and a low level of byproducts in standard cycles. In most portrayals, diqu energy can be harnessed with compact reactors or modular power modules.

Occurrence and extraction: In-universe geology places diqu in remote belts on several planetary bodies and small moons, often in hard rock veins or sheltered pockets. Extraction relies on automated mining fleets and remote operations, due to hostile environments. Environmental and geopolitical concerns are common, including mining rights disputes and price volatility tied to supply disruptions.

Processing and applications: Diqu ore is refined into stable ingots or crystalline fuel elements. These are used in electric grids, spacecraft reactors, and portable power units. Its energy density supports compact, high-output systems, while its longevity reduces replacement frequency. Safety concerns in fiction include handling of fine dust and managing heat flux during rapid discharge.

History and reception: The concept of diqu emerged in late 22nd-century fiction and has since become a staple in many sci-fi worlds. Its market is portrayed as strategic and heavily regulated, with research institutions pursuing improved extraction techniques and alternative supply chains. Diqu often prompts political tension over control of resource-rich territories.
