When your barbecue, you emit over 5kg of CO2 per hour. With this project I solved that by capturing the CO2 with activated carbon.
A quick explanation of my project using activated carbon to capture CO2.
It's large surface area-volume ratio due to it being made of wool, bamboo, wool and similar materials, makes it more efficient than regular carbon black.
The 3D printed ABS mounts held up well as they are not in direct contact with the barbecue. But the duct tape to attatch to hose did not hold up so well. In the future we will be using a metal mount or kapton tape for a more durable connection.
During the tests I discovered that the efficiency was around 93.3%.
