Last meeting, we built our own Direct Air Capture units, inspired by Dahl Winters’ Cyan unit. These systems operate at a small scale and allow individuals to understand the theory behind carbon removal(you can learn more about them here!). Once everyone joined one of the five groups led by an experienced leader, we had a five-minute brainstorming session to design our units. The end goal for each team was to decipher the most effective way to capture CO2 given limited materials, in a given one-hour time frame. With this in mind, team members had to decide between two different types of sorbents: Calcium Hydroxide (Ca(OH)2) or Zeolite 13x, along with taking into consideration factors such as size, surface area, and humidity. Then, each team got to pick their materials and got to building!
Ben and Micky will be testing the units this week, and they will be announcing the winners at our next General Meeting (10/03). Everyone had really strong builds, so it’s going to be interesting to see which team captured the most carbon.
