A lattice energy converter (LEC) is disclosed that produces ionizing radiation and/or electricity based on the thermal energy in the lattice of a specially prepared working electrode comprised in whole or in part of hydrogen host materials that are occluded with hydrogen or the isotopes of hydrogen and wherein the hydrogen host materials may include vacancies, superabundant vacancies, and other lattice defects. When the hydrogen host material is occluded with hydrogen, the LEC was found to self-initiate the production of ionizing radiation and, when the hydrogen host materials are in fluidic contact with a gas or vapor containing hydrogen or isotopes of hydrogen, the LEC was found to self-sustain the production of ionizing radiation. When the LEC includes one or more additional electrodes or electrode structures, the ionizing radiation was found to be converted to electrical energy. Materials that are normally considered to be radioactive are not required.

A hydride heat engine produces electricity from a heat source, such as a solar heater. A plurality of metal hydride reservoirs are heated by the heating device and a working fluid comprises hydrogen is incrementally move from one metal hydride reservoir to a success metal hydride reservoir. The working fluid is passed, at a high pressure, from the last of the plurality of metal hydride reservoirs to an electro-chemical-expander. The electro-chemical-expander has an anode, a cathode, and an ionomer therebetween. The hydrogen is passed from the anode at high pressure to the cathode at lower pressure and electricity is generated. The solar heater may be a solar water heater and the hot water may heat the metal hydride reservoirs to move the hydrogen. The working fluid may move in a closed loop.

This proposed system provides a method to generate electrical power for space-based orbiting satellites, probes, stations, habitations, and interplanetary missions. Electricity is generated by collecting the flow of ionized plasma in the solar system for low earth applications and in the solar wind beyond the earth's magnetosphere, then directing the plasma through a channel using the principle of magneto-hydrodynamics (MHD). The channel has conducting electrodes on two sides and a magnetic field directed orthogonally to the plasma flow direction. This results in an electrical current to power spacecraft functions such as batteries, communications, propulsion, guidance, navigation and control. This MHD generator has the potential of providing higher power generation density (e.g., watts/kg) for spacecraft than photo-voltaic panels. The design includes a control system to maintain voltage quality, regulate electromagnet power and control ion inlet scoop RF frequency and voltage in response to changing space ionized plasma conditions.
