Abstract
This paper describes Marangoni-like phenomena observed in externally homogeneous closed systems and a possibility of energy usage as seemingly perpetual motion. We often witness the inner surface of bottles containing liquid is sometimes wet even when it was kept closed and not agitated. Liquid drops flow down the wall continuously and do not stop; drop formation on the wall is seemingly ever lasting. These phenomena resemble so-called Marangoni effect, which is usually interpreted in terms of non-equilibrium effects either applied from the surroundings or contained in the system itself from the beginning. From the second law of thermodynamics, these phenomena cannot persist in externally homogeneous closed systems, because non-equilibrium effects cannot persist there. But author found spontaneous upward motion of water in closed glass bottles persisted where no external non-equilibrium effect seems to exist. This strongly suggests Marangoni-like phenomena persists in externally homogeneous closed systems. Author propses a possibility of energy usage as seemingly perpetual motion.
