Abstract: A system and method are provided for generating electric power from relatively low temperature energy sources at efficiency levels not previously available. The present system and method employ recent advances in low energy nuclear reaction technology and thermionic/thermotunneling device technology first to generate heat and then to convert a substantial portion of the heat generated to usable electrical power. Heat may be generated by a LENR system employing nuclear reactions that occur in readily available materials at ambient temperatures without a high energy input requirement and do not produce radioactive byproducts. The heat generated by the LENR system may be transferred through one or more thermionic converter devices in heat transfer relationship with the LENR system to generate electric power.

Abstract: A drive system with harmonic drive designed to meet the high power and torque requirements required to drive an aircraft independently on the ground is provided. The drive system includes an electric motor driven by a harmonic drive assembly that may be configured to be integral with the motor. This drive system with harmonic drive can be effectively installed in an existing aircraft nose wheel or main wheel without changes to other components.

Abstract: Improved low light vision and thermal imaging devices are provided. The devices of the present invention employ thermionic or thermotunneling cooling, with or without Avto Metals™, to ensure efficient operation under conditions of low illumination or the complete absence of illumination to detect emitted or reflected infrared and visible light radiation, significantly reducing thermal noise to produce superior image resolution and sensitivity within a small, lightweight footprint that will have a wide range of military, law enforcement, civilian, and other applications.

Abstract: A starter/generator machine for a turbine with a turbine enclosure, an air duct, and a plurality of fan blades is provided. The starter/generator machine includes a plurality of stator elements spaced at intervals in a ring shape adjacent to the air duct and a plurality of rotor elements mounted on the fan blades. The stator elements and the rotor elements are mounted to interact magnetically to exert a force sufficient to move the rotor elements. The stator elements are shaped to minimize air flow interference and are formed with a core, at least one pole, and multiple windings. The spacing between the stator elements and the rotor elements forms an air gap on the order of 5-10 mm, and the number of stator elements is different from the number of rotor elements.

Abstract: An improved thermoelectric converter device capable of effective and efficient high temperature operation is provided. The device includes at least a pair of spaced electrodes including substrates made from polished single crystal sapphire and active low and high temperature heat transfer regions contiguous with the electrodes and formed from materials selected to enhance heat transfer, particularly at high temperatures. The device is capable of more efficient operation and increased operating efficiencies over a wider range of temperatures than has heretofore been possible.

Abstract: A thermionic or thermotunneling gap diode device consisting of two silicon electrodes maintained at a desired distance from one another by means of spacers. These spacers are formed by oxidizing one electrode, protecting certain oxidized areas and removing the remainder of the oxidized layer. The protected oxidized areas remain as spacers. These spacers have the effect of maintaining the electrodes at a desired distance without the need for active elements, thus greatly reducing costs.

Abstract: The present invention relates to the manufacture of substrates for semiconductor device manufacturing particularly for applications that involved wafer-to-wafer bonding for SOI or MEMS structures. Although previous techniques have been applicable to single crystal wafers using bonding and annealing, the current techniques offer the unique capability of utilizing lower cost semiconductor materials, even when they contain dislocations or other growth associated stress fields; such as poly or multi-crystalline silicon and seed, or tail ends of CZ or FZ grown ingots. This invention provides a means of obtaining superior global and local flatness, along with nanoscale roughness variations across the surfaces so that cost and throughput are optimized.
