  • Patent number: 10794332
    Abstract: Systems, apparatuses, and methods for generating hot gases based on catalyzation involving flowing catalyst. Catalysis occurs in a flow-type mixing catalyzation channel in which a liquid catalyst mixes with a liquid reactant flowing in a desired flow regime, such as a striated (laminar) flow regime or a slug flow regime. Devices such as micro-thrusters for satellite and other applications and hot gas generators for powering another device, such as an electrical generator, can be made using one or more flow-type mixing catalyzation channels.

  • Patent number: 10794340
    Abstract: A first engine fuel, for example diesel fuel, is reformed (preferably via steam reforming) to produce syngas for use as a second engine fuel, with the fuels then both being used in an internal combustion engine to perform Reactivity Controlled Compression Ignition (RCCI). The syngas is produced and supplied to the engine as a supercritical fluid, thereby avoiding the pumping losses that would occur if syngas was pressurized for supply/injection. The reforming is done by a reformer which is provided as a unit with the engine (e.g., both the engine and reformer are onboard a vehicle), thereby effectively allowing use of a single fuel for RCCI engine operation.

  • Patent number: 10794369
    Abstract: A solar powered closed loop system and method for powering a cooling unit. The system and method provide a fully closed system that harnesses the power of the sun with a solar energy collecting device to generate vapor. The vapor has characteristics of high energy, expansion, and compressibility that enable travel through a plurality of conduits in the closed loop. The system generates vapor, carries the vapor and resultant gas, expands energy, and produces condensate through use of: a vapor expander, a compressor, a gas-liquid heat exchanger, an accumulator, an air-to-air heat exchanger, and a vapor condenser. Thus, through expansion, compression, and conversion different states of the vapor are controllably generated and disbursed for work. The work generated from the expansion and energy release from the vapors and gases produces work for powering the air-to-air heat exchanger, such as a cooling unit, and driving a load.

  • Patent number: 10794374
    Abstract: A microfabricated gas flow structure includes an array of vertical gas flow channels in a side-by-side parallel flow arrangement. Adjacent gas flow channels are separated by a thin wall having a thickness which can be an order of magnitude or more less than the channel width, offering exceptionally high area efficiency for the array. Channel walls can be formed from a dielectric material to provide the walls with sufficient integrity at nanoscale thicknesses and to provide thermal insulative properties in the lateral direction, thereby controlling power losses when the gas flow structure is employed as a Knudsen pump. The gas flow structure can be microfabricated as a monolithic structure from an SOI wafer, with the gas flow channels formed in the device layer and the heat sink formed from the handle layer.
