pyörivin
Pyörivin is a fictional term used in theoretical discussions of rotational energy devices. In this thought experiment, a pyörivin refers to a compact module designed to sustain rotation with minimal energy loss and to harvest energy from the rotating mass.
In the imagined design, a pyörivin employs near-frictionless bearings, magnetic or superconducting rotors, and an energy
Etymology and usage: The name is formed from Finnish pyöriä meaning to rotate, with a suffix -vin
