metrach

Metrach is a fictional mineral used as a major energy resource in several science fiction settings. Described as a dense crystalline ore, metrach is prized for its unusually high energy density and seemingly stable handling characteristics. In most narratives, it is mined from deep underground deposits and refined into compact fuel pellets or bars that can be fed into power cores or fusion reactors. The exact mechanism by which metrach releases energy varies between works, with some depictions presenting a controlled, low-waste reaction, while others describe radiation byproducts and complex waste management requirements. Because of its value, metrach trading often drives political tension and mining activity in the fictional economy.

Etymology and naming: The term metrach is not standardized across works; in some texts it is said to derive from meta- (beyond) and rach (charge) or arch (energy). Others treat it as a proper name.

Mining and processing: Metrach is typically described as rare and geographically concentrated, requiring specialized ore processing facilities. Extraction is capital-intensive and carries environmental and safety risks, including sudden energy release if misprocessed.

Applications: In spacecraft and terrestrial power grids within fiction, metrach provides a reliable energy source with high energy density and, in some versions, minimal long-term radioactive waste. Its scarcity and the cost of refinement shape political and economic dynamics.

Metrach remains a fictional concept used to explain energy systems, mining economies, and political tension in speculative worlds; see also fictional minerals and energy sources in fiction for related ideas.
