Thermophotovoltaic electrical power generator

A power system comprising:

• at least one vessel capable of a maintaining a pressure of below, at, or above atmospheric;
• reactants, the reactants comprising:
• H2O gas or vapor;
• H2 gas;
• and a molten metal, wherein the H2O gas or vapor and H2 are flowed into the vessel and into the molten metal;
• at least one ignition system comprising a source of electrical power to deliver electrical energy between at least one set of electrodes that are separated to form an open circuit and
• a molten metal injection system for injecting the molten metal in contact with the H2O gas or vapor and H2 gas between the electrodes and, such that the open circuit is closed by the injection of the molten metal between the electrodes, wherein the molten metal injection system comprises an electromagnetic pump comprising at least one magnet providing a magnetic field and current source to provide a vector-crossed current component, and
• wherein the source of electrical power induces a current to flow between the electrodes when the circuit is closed to deliver the electrical energy to result in the formation of light;
• and
• at least one power converter or output system of at least one of light output produced from delivering electrical energy to the reactants to electrical power.
