Techniques for purifying gases, and associated systems and methods are disclosed. A representative system includes an absorption vessel that can separate impurities from an input gas, a regeneration vessel that can release the impurities from the solvent, a rich solvent storage vessel, and a lean solvent storage vessel. The system can include a solar concentrator array and a thermal storage unit for storing the thermal energy generated by the solar concentrator array.

A broadband acoustic lens and method of designing same is provided for focusing an incident acoustic wave. The broadband lens includes a plurality of concentric rings, where each concentric ring of the plurality of concentric rings has a ring width, and a plurality of gaps, where each gap of the plurality of gaps has a spacing. The concentric rings are separated by a spacing corresponding to a gap of the plurality of gaps. The widths of the plurality of concentric rings and the spacings of the plurality of gaps are arranged such that the incident acoustic wave is focused to a spot within a sub-wavelength of the incident acoustic wave in air. The arrangement of the widths of the plurality of concentric rings and spacings of the plurality of gaps is aperiodic.
