The specific tools, energy sources, and infrastructures employed by civilizations operating at Kardashev-scale levels. These are not just bigger versions of our tech; they are qualitatively different concepts. Think star-lifting equipment to mine a sun's hydrogen, spacetime-altering engines for moving solar systems, or quantum-consciousness networks spanning a galaxy. The technology ceases to be something you hold and becomes an environment you live within, often blurring the line between a machine and a natural cosmic phenomenon.
Kardashevian Technologies Example: A Shkadov Thruster—a stellar engine that uses a giant mirror to turn an entire star into a rocket for moving a solar system through space—is a quintessential Kardashevian Technology. It's a tool, but its "handle" is a star and its "power cord" is gravity itself.
