  • Publication number: 20230250978
    Abstract: A system having an enclosure for containing a solution. An atomizer is in communication with an interior of the enclosure and the solution for generating an aerosolized particle mist within the interior of the enclosure. A positive pressure device is in communication with the interior of the enclosure for generating a positive pressure within the enclosure relative to an atmosphere outside of the enclosure. An ejection nozzle having a tortuous path is provided, wherein an entrance of the tortuous path is in communication with the interior of the atomizer and an exit of the tortuous path is in communication with the atmosphere outside of the enclosure.

  • Publication number: 20170341988
    Abstract: A system and method for disposing carbon dioxide is disclosed. The system includes a foam generator that generates a plurality of disposable foam vessels from a polymer based solution mixed with water and captured carbon dioxide from the atmosphere. The plurality of disposable foam vessels contains an amount of carbon dioxide. The plurality of disposable foam vessels is mixed in a cementitious material with a set of mixers. In a preferred embodiment, the set of mixers is a concrete mixing plant. During the curing process of the cementitious material the plurality of disposable foam vessels dissipates allowing for a timely release of CO2 to chemically react with the surrounding cementitious material. This irreversible chemistry change permanently disposes of the carbon dioxide.
