Embodiment Construction

[0009]There are now described systems and methods for their use for the production of high thermal energy which may be harvested as a substantial anaerobic energy source for powering vehicles such as unmanned-underwater vehicles (UUVs) or unmanned aerial vehicles (UAVs), other small robotics, backup or regular underwater power sources (e.g., for oil rigs), or as an emergency power source in flooded or disaster areas.

[0010]In some embodiments, the systems rely on the use of a stream of molten depassivating agent flowing through a circuit, and passing through a source of fuel, then a source of an oxidizing agent, such as water, in small amounts with respect to the depassivating agent such that the thermodynamic properties of the depassivating agent regulate the thermal energy produced. The stream is then passed through a heat harvester and a waste purifier before being cycled back. Optionally, the hydrogen also produced in this system may be used as an additional fuel for power genera...

Abstract

Aluminum may be used as a fuel source to power small vehicles, unmanned vehicles or underwater vehicles, other small robotics, backup or regular underwater power sources (e.g., for oil rigs), or as an emergency power source in flooded or disaster areas. Reactors are described that harvest energy produced by the exothermic oxidative reaction of aluminum or an aluminum alloy with water, with the assistance of liquid gallium as a depassivating agent.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority to U.S. Provisional Patent Application No. 61 / 636,100 filed Apr. 20, 2012, the disclosure of which is incorporated by reference herein in its entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]This invention was made with government support under Contract No. FA8721-05-C-0002 awarded by the U.S. Air Force. The U.S. government has certain rights in the invention.TECHNICAL FIELD[0003]The present invention relates to electrochemical reactors, and more particularly, to reactors for the production of energy from the oxidation of aluminum.BACKGROUND ART[0004]It is known in the art that aluminum can be used as a fuel for the production of hydrogen which can then be harvested or used in fuel cells. But, because aluminum forms a stable protective layer upon oxidation, which limits its further reaction with the oxidant, aluminum-based systems require the use of a depassivating agent...
