Abstract
A system for large scale capture of atmospheric carbon dioxide while exposed to air and weather in an outdoor environment, includes a large flat slab with a perimeter wall projecting above its surface; one or more rotary fans, providing uniform, high volume, low velocity, turbulent air flow over the entire slab surface; a transport system transferring powder—a particulate material mixed with air—to and from all locations on the slab or on an overlying mesh screen, a kiln, closed to outside air, and a compressor. The transport system includes either a vacuum/deposition system or a conveyor system with one or more conveyors. The kiln heats the particulate material, delivered by the transport system from the slab, to output released carbon dioxide, previously absorbed by the particulate material in the powder, to the compressor for compression, and either the heated particulate material, or a processed version of it.
