Abstract: Thermionic generators are described herein that include a variety of features that allow the devices to efficiently and effectively convert large amounts of thermal energy directly to electrical energy, such as in the form of currents and/or voltages. For example, the thermionic generators can be used to generate an electron beam from a thermionic emission device, and focus or shape the electron beam in such a way that allows the energy of electrons in the electron beam to be captured and converted to electrical energy.

Abstract: Integrated devices comprising integrated circuits and energy storage devices are described. Disclosed energy storage devices correspond to an all-solid-state construction, and do not include any gels, liquids, or other materials that are incompatible with microfabrication techniques. Disclosed energy storage device comprises energy storage cells with electrodes comprising metal-containing compositions, like metal oxides, metal nitrides, or metal hydrides, and a solid state electrolyte.

Abstract: Energy conversion systems that may employ control grid electrodes, acceleration grid electrodes, inductive elements, multi-stage anodes, and emissive carbon coatings on the cathode and anode are described. These and other characteristics may allow for advantageous thermal energy to electrical energy conversion.
