Abstract: A method for producing a synthetic fuel from hydrogen and carbon dioxide comprises extracting hydrogen molecules from hydrogen compounds in a hydrogen feedstock to produce a hydrogen-containing fluid stream; extracting carbon dioxide molecules from a dilute gaseous mixture in a carbon dioxide feedstock to produce a carbon dioxide containing fluid stream; and processing the hydrogen and carbon dioxide containing fluid streams to produce a synthetic fuel. At least some thermal energy and/or material used for at least one of the steps of extracting hydrogen molecules, extracting carbon dioxide molecules, and processing the hydrogen and carbon dioxide containing fluid streams is obtained from thermal energy and/or material produced by another one of the steps of extracting hydrogen molecules, extracting carbon dioxide molecules, and processing the hydrogen and carbon dioxide containing fluid streams.

Abstract: A system for capturing CO2 from a dilute gas source includes a gas-liquid contactor including a housing coupled to a plurality of structural members; one or more basins positioned within the housing and configured to hold a CO2 capture solution, the one or more basins including a bottom basin; one or more packing sections positioned at least partially above the bottom basin; a fan operable to circulate a CO2-laden gas through the one or more packing sections; and a liquid distribution system configured to flow the CO2 capture solution onto the one or more packing sections.

Abstract: A communication system transfers user data messages to users. The system stores the user data messages in association with message stream identifiers and message delivery metrics. The system processes the message delivery metrics to enter the user data messages into a plurality of delivery queues associated with multiple message transmission systems. The system receives a data request indicating a message stream identifier and a message transmission system, and in response, identifies a message set and associated delivery metrics. The system receives a data instruction indicating new delivery metrics, and in response, re-enters the message set into the delivery queue. The communication system transfers the user data messages based on their associated delivery queues over data networks for receipt by the users.

Abstract: A method of generating a user identifier is disclosed. The method comprises identifying, by a client, that the client does not have a device identifier associated with the device, wherein the device identifier is a device system identifier unique to the device. The method also comprises requesting, by the client, the device identifier from the device in response to identifying that the client does not have the device identifier. The method further comprises receiving, by the client, the device identifier. The method also comprises masking, by the client, the device identifier with client logic. The method further comprises generating, by the client, the user identifier based on masking, wherein the user identifier is unique to the device, and wherein the user identifier is attached to one or more interactions with one or more applications used by the device.
