NOVELTY - Powder of red ocher (ferric oxide) is reduced with powder of dry aluminum, to aluminum oxide. 181.8 kcal of heat is liberated during the reduction reaction. The water vapor plasma, liberated heat and exhaust gas containing the metal emitted during the reduction reaction as conductive material of magnetohydrodynamic power are used in the generation of electric power.    USE - For generating electric power.    ADVANTAGE - The method enables efficient and economic generation of electric power and pure hydrogen.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) generation of magnetohydrodynamic power, which involves using the exhaust gas of incineration of refuse using jet flame of hydrogen by decomposition of hot water vapor or combustion heat;    (2) generation of steam turbine electric power, which involves using the remaining heat of the magnetohydrodynamic power generation;    (3) generation of hydrogen, which involves reacting iron, aluminum, zinc and zinc or magnesium with hot water vapor or steam turbine electric power generation;    (4) generation of hydrogen molecule of dissolved liquid aluminum, which involves generating hydrogen of hot atomic state using the reaction heat of magnetohydrodynamic power generation, reducing carbon dioxide, detoxifying freon, and reducing aluminum oxide produced during the magnetohydrodynamic power generation;    (5) conversion of thermal energy, which involves recycling remaining heat of water vapor utilized for hot section using the semiconductor to hot section, utilizing the tap water cooled with dry ice of carbon dioxide for low temperature portion, vaporizing aqueous ammonia of operation medium passing along a pipe by hot section and liquefying ammonia in low temperature portion;    (6) recycling of carbon dioxide and ammonia, which involves cooling the condensate of iron smelting electric power generation, refuse incineration electric power generation or thermal electric conversion;    (7) reduction installation of iron oxide by aluminum;    (8) simple incineration system, which carries out incineration of refuse of magnetohydrodynamic power generation; and    (9) fuel cell, which uses sodium peroxide.
