Abstract: The techniques described herein relate to systems and methods for capturing CO2, including an air process zone, a sorbent wheel, a humid zone, and a CO2 storage material. An inlet air stream can pass through the air process zone, and the sorbent wheel can rotate such that a portion of the sorbent wheel is alternatively exposed to the inlet air stream and to humid air in the humid zone. Sorbent material in the sorbent wheel can capture CO2 from the inlet air stream when in the air process zone and release the CO2 when exposed to the humid air in the humid zone. The CO2 storage material can store the CO2 after the CO2 is released by the sorbent material in response to being exposed to the humid air in the humid zone.

Abstract: Methods and systems include providing a modular frame having a plurality of frame sections that are connectable to each other at a joint area. A pin extends from the joint area of the modular frame. A polymer solution is dispensed through a syringe, and the pin passes by and contacts a droplet of the polymer solution as the modular frame rotates. Fibers are formed by using the pin to draw out the fibers from the droplets of the polymer solution. The fibers are deposited on the modular frame. In some cases, the plurality of frame sections of the modular frame are arranged on a base in a first arrangement. After the fibers are deposited, the plurality of frame sections are reconfigured into a second arrangement different from the first arrangement to form a fiber component of an air flow device.
