An ionization chamber is provided with a series of parallel plates spaced from each other and with holes passing therethrough. Alternating plates have either a highest high voltage or a lower high voltage provided thereto, such as through a DC transformer coupled to an electric power source. Holes in alternating plates are preferably offset so that airflow through the plates occurs along curving pathways. The plates are sufficiently highly charged to cause carbon dioxide to be ionized and for carbon ions to become trapped within wells defining lowest regions of electric charge within an electric field inside the ionization chamber. Fans control airflow through the ionization chamber. A dehumidifier is provided upstream of the ionization chamber to reduce moisture content within the incoming gas. After the carbon has collected within the wells, harvesting of the carbon ions as carbon nano particle powder can occur within a carbon cache.
