Long range and long duration portable power require some kind of chemical fuel for practical use. Combustion of metals is a neglected method of producing power in a way that can emit no carbon dioxide pollutants. Here we propose a system using a thermophotoelectric (TPV) device to convert the emitted IR and visible light from the oxidation of aluminum directly into electrical power. A qualitative overview of the advantages of this scheme is presented, along with a simple techno-economic analysis of aluminum combustion. The advantages of this device warrant additional research into this area.
