Abstract: The present application describes machines and methods that leverage enabling technologies such as robotics, sensing, machine learning, and wireless internet coverage (e.g., 5G cell coverage) in order to monitor photovoltaic systems such as solar sites. Machines according to the present disclosure can be operated remotely by users to traverse a solar site and perform a series of inspection steps, such as via an online portal. Autonomous and semi-autonomous operations are also possible. These methods and machines can eliminate the need for a technician to visit the site in person for routine inspection, and can provide better information when a site alarm is triggered so that if a technician does need to visit the site, he or she is better prepared. Also described herein are systems and methods for inventorying solar sites, and systems and methods for inspection of structure-mounted photovoltaic systems.

Abstract: In a general aspect, interfacial surface structures for removing carbon dioxide from a gaseous feed are presented. In some cases, a method of removing carbon dioxide gas from a gaseous feed includes wetting surfaces of an interfacial surface structure in a gas-liquid contactor with an alkaline capture solution. The gaseous feed containing the CO2 gas is passed across the wetted surfaces of the interfacial surface structure to dissolve the CO2 gas in the alkaline capture solution. A CO2-rich alkaline capture solution is collected from the gas-liquid contactor. The CO2-rich alkaline capture solution includes dissolved CO2 gas from the gaseous feed.

Abstract: In a general aspect, a carbon dioxide removal system is presented. In some cases, a gas-liquid contactor is wetted with an alkaline capture solution. A first flow from a first gaseous feed including CO2 from a first source is directed to interact with the alkaline capture solution in the gas-liquid contactor, which forms a first CO2-rich alkaline capture solution. A second flow from a second gaseous feed including CO2 from a second, distinct source is directed to interact with the first CO2-rich alkaline capture solution, which forms a second CO2-rich alkaline capture solution. In some cases, the second flow is independent of the first gaseous feed, and a concentration of CO2 in the second CO2-rich alkaline capture solution is higher than a concentration of CO2 in the first CO2-rich alkaline capture solution. CO2 can be separated from the second CO2-rich alkaline capture solution.
