摘要： A method including capturing carbon dioxide (CO2) from air (e.g., atmosphere) in an absorber in which the air contacts a base (e.g., a hydroxide, such as potassium hydroxide KOH and/or sodium hydroxide (NaOH)) to produce a carbonate (e.g., potassium carbonate (K2CO3) and/or sodium carbonate (Na2CO3)); precipitating one or more (e.g., carbonate) salt from an aqueous solution comprising salt (a brine) to provide an aqueous solution comprising a chloride (e.g., potassium chloride (KCl) and/or sodium chloride (NaCl)); using electrochemical regeneration to convert the chloride to electrochemically regenerated product comprising the base (e.g., KOH and/or NaOH); and recycling at least a portion of the electrochemically regenerated product comprising the base to the capturing of the CO2 from the air. A system for carrying out the method is also provided.

摘要： A system for wireless transmission of power in deep subsurface monitoring includes a casing, an oscillating current source configured to energize the casing, and a wireless telemetry module disposed on the casing. The wireless telemetry module includes a shell, a toroidal antenna disposed within the shell and configured to collect electrical energy from the energized casing, a telemetry transceiver control unit disposed within the shell, a battery pack disposed within the shell, a downhole signal acquisition unit disposed within the shell, and a sensor interface disposed within the shell. The battery pack is configured to store the collected electrical energy. The telemetry transceiver control unit is configured to generate a binary code to drive the toroidal antenna.
