As research fields go, tribology is concerned with the rather mundane problem of increasing the efficiency of machines by reducing the loss of energy from friction. Like other emerging technologies, nanotribology goes beyond this traditional engineering problem in quest of a pure phenomenon – superlubricity and frictionless motion. The problem of attaining frictionless and thus, in principle, endless
motion is taken to be one of producing an absolutely clean surface, free of atomic grime and thus also of any kind of lubricant. I will introduce this theory of frictionless motion and its rogue offspring, the perpetuum mobile. In an apparently paradoxical manner, the nanotechnological quest for a pure phenomenon yields a proof of concept that lacks technological significance: frictionless motion can be demonstrated under laboratory conditions that cannot be translated into practice – and it exemplifies a theory that is too good to be true.
