NOVELTY - The water purification system comprises a water electrolysis system (4) for generating hydrogen and oxygen from water, a combustion chamber (6) for combusting hydrogen from the electrolysis system in oxygen from the electrolysis system to generate heated water vapor, a hydrogen channel (10) disposed to transport hydrogen from the water electrolysis system to the combustion chamber, an oxygen channel (8) disposed to transport oxygen from the water electrolysis system to the combustion chamber, and a water vapor production chamber (12) for generating water vapor from water.    USE - The system is useful for purifying water such as salt water or other non-potable water source.    ADVANTAGE - The system ensures efficient purification of water with high purity and quality and without any contaminants such as microorganism, and increases the rate of production of water vapor within water vapor production chamber.    DETAILED DESCRIPTION - The water purification system comprises a water electrolysis system (4) for generating hydrogen and oxygen from water, a combustion chamber (6) for combusting hydrogen from the electrolysis system in oxygen from the electrolysis system to generate heated water vapor, a hydrogen channel (10) disposed to transport hydrogen from the water electrolysis system to the combustion chamber, an oxygen channel (8) disposed to transport oxygen from the water electrolysis system to the combustion chamber, a water vapor production chamber (12) for generating water vapor from water, a condensation chamber (14) disposed to receive water vapor from both the combustion chamber and the water vapor production chamber for condensing the water vapor into purified liquid water, and a water vapor conduit (16) between the water vapor production chamber and the condensation chamber. The reception of the water vapor from both the combustion chamber and the water vapor production chamber produces purified liquid water than receiving water vapor from only the combustion chamber. The heated water vapor from the combustion chamber traveling from the combustion chamber into the condensation chamber generates a vacuum on the water vapor conduit. The water vapor is drawn from the water vapor production chamber into the condensation chamber. The water electrolysis system includes an electrolytic chamber, and a direct current voltage source having an anode and a cathode both disposed in the electrolytic chamber so that water in the electrolytic chamber is decomposed into oxygen and hydrogen at the anode and cathode respectively. The system further includes an external combustion engine disposed to utilize the combustion of hydrogen within the combustion chamber as a source of external combustion, an electrical power generation system powered by the external combustion engine and providing electrical power to the direct current voltage source, a unit for capturing air heated from a water electrolysis process and a combustion process within the electrolytic chamber and the combustion chamber, a unit for introducing the captured heated air into the combustion chamber to augment the vacuum generated by the heated water vapor traveling from the combustion chamber to the condensation chamber, an oxygen storage system in fluid communication with the oxygen channel, and a hydrogen storage system in fluid communication with the hydrogen channel. The capturing unit includes a jacket surrounding the electrolytic chamber. The introduction unit includes a heated air channel between the jacket and the combustion chamber. The water vapor production chamber is a chamber for boiling water to produce water vapor, and includes a water container and a heat source disposed adjacent to the water container. An INDEPENDENT CLAIM is included for a method for purifying water.    DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a system for purifying water.
