A Direct Air Capture (DAC) Machine is a technology designed to filter and capture carbon dioxide (CO2) directly from the atmospheric air. This machine operates by pulling ambient air through a chemical system that selectively absorbs CO2. Once captured, the CO2 can either be stored underground to mitigate climate change or reused for industrial applications, such as synthetic fuel production, carbonation in beverages, or enhanced oil recovery. DAC machines are seen as a crucial tool in the effort to reduce atmospheric CO2 levels and address global warming.
