ABSTRACT:
Methods and apparatus for the generation of energy from the oxidation of aluminum comprise means for breaking up the continuity of the passivating oxide layer on the aluminum surface by exposing said surface to a mercury-, indium- or gallium-containing substance, exposing the surface-treated aluminum to a fluid which is capable of oxidizing said aluminum, and withdrawing useful energy from the oxidation reaction. The oxidizing fluid may be air, with the energy-withdrawing means a thermal engine, preferably of the closed cycle type. Alternatively, the fluid may be an aqueous electrolyte, preferably a neutral saline, mildly alkaline or mildly acidic solution, with the energy-withdrawing means comprising an electrochemical cell.
