Abstract: Some embodiments are directed to a system for extracting carbon dioxide from a fluid. The system can include a fluid source and a reactor. The reactor can include one or more chambers, and each chamber can include one or more monoliths for adsorbing carbon dioxide from the fluid. The chambers can be alternatively unsealed for a contacting mode and sealed for a regeneration mode. A power source can provide an electric current to the monoliths to release carbon dioxide adsorbed by the monoliths. Each chamber can include an array of monoliths. Each monolith can include a sorbent that adsorbs carbon dioxide from fluid. The system can include modular components such that the number of reactors can be increased or decreased.

Abstract: A system, apparatus and methods are described for extracting carbon dioxide from air. The system may receive air blown over a contactor. The contactor can be coupled to a cooling tower. The contactor may comprise sorbent material to absorb carbon dioxide from the blown air. The sorbent material may be transported and placed into a regeneration reactor. The carbon dioxide in the sorbent material may be extracted via the regeneration reactor. The extracted carbon dioxide may be pressurized into and stored in a pressurized container.

Abstract: An IC includes logic groups each including a launch and a capture FF with a logic cloud in between. A power switch is in series with a power supply node of the logic groups. The logic groups have a clock-gating and power control (PCGC) block for dynamically generating a power supply enable (PS_EN) signal output coupled to a control node of the power switch and a clock output (CLK_OUT) signal coupled to a clock input of the launch or capture FF for clocking the logic groups. The PCGC blocks receive an EN signal and a CLK_IN signal and dynamically generate the PS_EN signal and CLK_OUT signals. During clock cycles at least one logic group(s) does not contribute to an intended logic result for the IC the CLK_OUT signal disables switching of at least a portion of the logic group(s) while the PS_EN signal turns off power to the logic group(s).
