Abstract: In a general aspect, a carbon dioxide (CO2) removal system uses geothermal energy. In some implementations, a method to remove CO2 gas from a gaseous feed includes directing a gaseous feed to interact with an alkaline capture solution in a first gas-liquid contactor. A first portion of CO2 from the gaseous feed dissolves into the alkaline capture solution to form a CO2-rich alkaline capture solution. Steam is generated using heat from a geothermal heat source, and the steam heats the CO2-rich alkaline capture solution in a second gas-liquid contactor. A second portion of the CO2 is separated from the CO2-rich alkaline capture solution in the second gas-liquid contactor to form a CO2-lean alkaline capture solution. The CO2-lean alkaline capture solution is directed to the first gas-liquid contactor.

Abstract: Methods, systems and apparatus, including computer programs encoded on computer storage media for unmanned aerial vehicle flight for performing an inspection of land, property, structures or other objects. Automated aerial surveys allow a UAV to obtain aerial data without human manual control of a UAV. For certain aerial surveys, a UAV is not capable of completing the survey without refueling, or exchanging out used batteries for fresh batteries. For such aerial surveys, a method and system is needed to allow an operator to automatically perform an aerial survey while determining battery usage and replacement. Also, in circumstances where manual control of the UAV is needed, contingency-based software controls may be needed.

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: Systems and methods for altering colors of pixels of images produced by cameras using a lens. A plurality of generated images are received, and color channel values and luminance values of image pixels are determined. Benchmark U-color thresholds and V-color thresholds are established based on the color channels and luminance associated with the pixels. A first image generated using a first lens of a first camera is received. U-color values and V-color values associated with first pixels of the first image are determined. A uniformity score associated with the first lens is received. The benchmark U-color and V-color thresholds are altered based on the uniformity score. The U-color values and V-color values of the first pixels are corrected in response to the U-color values being within the altered U-color thresholds and the V-color values being within the altered V-color thresholds.

Abstract: HET classifiers, which learn a multivariate Gaussian distribution over prediction logits, perform well on image classification problems with hundreds to thousands of classes. However, compared to standard classifiers (e.g., deterministic (DET) classifiers), they introduce extra parameters that scale linearly with the number of classes. This makes them infeasible to apply to larger-scale problems. In addition, HET classifiers introduce a temperature hyperparameter, which is ordinarily tuned. HET classifiers are disclosed, where the parameter count (when compared to a DET classifier) scales independently of the number of classes. In large-scale settings of the embodiments, the need to tune the temperature hyperparameter is removed, by directly learning it on the training data.

Abstract: An apparatus includes a captured carbon dioxide input. The captured carbon dioxide input is coupled to receive captured carbon dioxide from a direct air capture system. The apparatus uses the captured carbon dioxide as a low global warming refrigerant to provide cooling functionality in automotive, commercial, and industrial applications, or other operations involving low global warming refrigerants. In various embodiments, the apparatus is a refrigeration apparatus or a heat pump apparatus. Low global warming carbon dioxide refrigerant is natural, non-toxic, non-flammable, and abundant when obtained from a direct air capture system. Moreover, carbon dioxide refrigerant has a high heat transfer coefficient and has a global warming potential (GWP) of one. Carbon dioxide refrigerant is a more sustainable and efficient coolant option than common refrigerants, such as R22, R152, R404a, and R1234yf refrigerants.

Abstract: A carbon processing system comprises an air mover and a multi-stage reactor. The multi-stage reactor processes ambient air and generates carbon dioxide and generates exhausted gas released to ambient air. In operation, air contacts the base solution via the air mover. The air reacts with the base solution thereby generating a base solution having carbon dioxide and generating exhaust (absorption reaction). Next, the exhaust is released from the reactor. Next, heat is applied to the base solution having carbon dioxide thereby generating carbon dioxide and generating a base solution without carbon dioxide (desorption reaction). The base solution without carbon dioxide generated after applying heat is reusable in processing new air. The absorption reaction and desorption reaction are reversible reactions resulting in regeneration of the base solution into its form prior to contact with the air yielding high scalability and less processing volume as required by many conventional carbon processing techniques.
