  • Patent number: 10658164
    Abstract: There is a need to produce electric power by means that provide low pollution and high efficiency. Thermionic energy conversion (TEC) systems enable the direct conversion of energy from thermal to electric, based on the emission of electrons from a heated cathode, Diamond is an ideal material for the cathode because of its high temperature mechanical stability, its ability to be created with low resistivity, and its strong tendency to emit electrons. The efficiency of current TEC systems is not practical, as above approximately 700° C. the current produced decreases. The presence of hydrogen at the electron-emitting surface is required to enhance thermionic emission. The present invention provides a resupply of hydrogen to the emitting surface by diffusion of hydrogen through the diamond cathode, and enables efficient operation of TEC systems at temperatures well above the current limit; practical systems for direct conversion of heat to electricity are thus enabled.

  • Patent number: 10388842
    Abstract: A thermoelectric generator system of an engine is provided and includes an insulating heat protective cover that is mounted within an engine. Additionally, a unit is disposed at an upper end of the heat protective cover to uniformly distribute heat energy to use the heat protective cover mounted at an upper end of an exhaust manifold of the engine to protect a wiring from exhaust heat. Accordingly, heat energy discarded from the exhaust manifold is absorbed to generate electricity using the waste heat discarded from the exhaust manifold without affecting the catalyst to improve the fuel efficiency of the internal combustion engine. Further, heat is transferred by conduction at a particular temperature or greater and heat is transferred by radiation and convection at a temperature less than the particular temperature to increase the efficiency.

  • Patent number: 10323487
    Abstract: The disclosed embodiments include systems and methods to generate electrical power in a downhole environment. In one embodiment, the system includes a thermoelectric generator operable to convert a temperature gradient across a section of the thermoelectric generator into electrical energy and deployed in a wellbore. The system also includes a pressure control device positioned proximate the thermoelectric generator and having a fluid flow path for a fluid flowing through the pressure control device and across the thermoelectric generator such that an absolute pressure of the fluid decreases when the fluid flow out of the pressure control device and across the thermoelectric generator. A temperature of the fluid changes as the fluid flows out of the thermoelectric generator and across the thermoelectric generator due to a change in the absolute pressure of the fluid. The temperature gradient across the thermoelectric generator is due to change in the temperature of the fluid.
