Abstract: Methods and apparatus for capturing carbon dioxide from ambient air and delivering said carbon dioxide to an enclosed environment are described. In general, the methods and apparatus comprise contacting a packed bed or fluidized bed device with a stream of ambient air, wherein the packed bed or fluidized bed device comprises a humidity-sensitive sorbent material that adsorbs carbon dioxide from the ambient air; contacting the packed bed or fluidized bed device with a stream of humid air to release the adsorbed carbon dioxide; delivering the released carbon dioxide to an enclosed environment; and optionally, repeating the steps of contacting the packed bed or fluidized bed device with ambient air and humid air in an alternating fashion.

Abstract: Devices, systems and methods for using photosynthetic biomass to purify water, reduce indoor air pollution, remove greenhouse gases including CO2 from outdoor atmospheric air, and produce biofuel, food products, and fertilizer are provided herein. Also provided herein are systems and methods for enhancing growth of a photosynthetic biomass in a greenhouse.

Abstract: A display assembly supports a display item in a visually prominent orientation and is removably attachable to an article of clothing in a nondestructive manner. The display assembly includes a docking assembly removably attached to the article of clothing and having a base unit with one or more dock interconnects and a display interconnect, and a docking unit having one or more base interconnects. A display unit includes a display holder having a display chamber dimensioned to support the display item in the visually prominent orientation. The display unit also includes a docking interconnect, wherein the display unit is attachable to and detachable from the docking assembly with a single hand of the user via an operative engagement of the docking interconnect with the display interconnect of the docking assembly.
