CYAN (mission)

The CYAN mission began under the leadership of Dahl Winters in January 2021. The objective has been to develop a miniature, open-source device that removes small amounts of CO2 from the air using simple, inexpensive off-the-shelf components.

There is a project overview and some other documentation at GitBook Summary - CYAN and at
