Definitions

  • a “point source” refers to any single identifiable source of pollution from which pollutants are discharged, such as a discharge pipe, power generation flue stack, drainage ditch, and ship or factory smokestack.
  • a discharge pipe power generation flue stack
  • drainage ditch drainage ditch
  • factory smokestack There are two methodologies for carbon removal: naturebased and technology-based methods.
  • Direct air capture uses large fans to move air through a filter to absorb CO2 (i.e., a forced air system). Forced air systems are typically powered, at least in part, by fossil fuel-generated electricity.
  • Direct air carbon capture and storage extracts CO2 from the air and stores it in geological formations underground.
  • Bioenergy with carbon capture and storage uses atmospheric CO2 absorbed by plants. The plants are burned to produce energy and release CO2, which, in turn, is captured and stored underground.
  • CCS carbon capture and sequestration
  • Hie present invention provides an apparatus that moves air across or through the inside of tire apparatus.
  • the apparatus can be used to move air across or through the CO 2 reactive agents to capture CO 2 directly from the atmosphere.

This draft or ventilation moves air across or through tire inside of the apparatus and, if present, the CO2 reactive agent, which binds CO2.

  • Tire reflective portion of the apparatus if present, is not exposed to heat (e.g., sun) and will stay cool. Exposing the apparatus to heat, and wind as well, creates a temperature/pressure differential within the apparatus. Warm air, having a lower density, will flow out the top of the apparatus, while cooler air flows into the bottom of the apparatus. This draft or ventilation moves air across the CO2 reactive agent binding CO2.
