NOVELTY - The autonomous distillation system comprises a pumped water distiller (2), a heat accumulating system (3), a liquefaction system of the water vapor obtained in the distiller, and a clean water tank (7), to which the distilled water coming from the liquefaction system arrives. The water distiller comprises an inlet of water to be distilled, pipes containing a secondary heat-transfer fluid located in the lower part of the distiller, and heat collection upper ducts. The heat accumulating system comprises an inlet and an outlet for the secondary heat-transfer fluid of the distiller pipes.    USE - The autonomous distillation system is useful for harnessing renewable energy such as solar energy, wind energy, geothermal energy and marine energy.    ADVANTAGE - The autonomous distillation system can be efficiently and simply manufactured with long service life, and ensures easy, rapid and economical harnessing of abundant, accessible and clean renewable energy without contaminating the natural environment and generating waste.    DETAILED DESCRIPTION - The autonomous distillation system comprises a pumped water distiller (2), a heat accumulating system (3), a liquefaction system of the water vapor obtained in the distiller, and a clean water tank (7), to which the distilled water coming from the liquefaction system arrives. The water distiller comprises an inlet of water to be distilled, pipes containing a secondary heat-transfer fluid located in the lower part of the distiller, and heat collection upper ducts. The heat accumulating system comprises an inlet and an outlet for the secondary heat-transfer fluid of the distiller pipes for heating the fluid, and an enclosed tank. The enclosed tank comprises a coil (1) present in the lower part of the enclosed tank, where a heat transfer fluid heated by thermal energy is present inside the coil, and resistors supplied by electric power present in the upper part of the enclosed tank. The liquefaction system comprises a medium through which the water vapor flows, a medium through which a liquid flows at room temperature, a heat exchanging area present between the water vapor and the liquid, so that the liquid initially collects the heat of the water vapor at room temperature and reduces the pressure of the area through which the water vapor flows, a liquefaction tank through which the water vapor flows, an inner circulation pipe through which the water vapor flows, an outer insulating pipe through which water flows at room temperature, an outer cooling tank through which water flows at room temperature, and a vault such as a complementary liquefaction system comprising a water vapor disperser through which the water vapor flows, a water disperser through which water flows at room temperature and a tank present at the base of the vault, where the water vapor disperser and the water disperser are located inside the vault as the heat exchanging area. The liquefaction tank has ducts through which water flows at room temperature. The inner circulation pipe has a longitudinal axis coaxial to the longitudinal axis of the outer insulating pipe, which has the diameter greater than the inner circulation pipe. The outer and inner pipes are joined by fastening points or ribs, which create completely independent areas through which the carrier cooling liquid circulates.
