I've read about this neat process for extracting CO2 from the atmosphere. You place a ultra compact box in the ground containing it's own building instructions and tooling for separating CO2 in to oxygen and building giant structures of the carbon. It's apparently called photosynthesis.
- adrianN 8y agoYou're joking, but producing biochar is actually a decent way of doing carbon capture that doesn't require any fancy technology. You even get some energy out of it. Unfortunately you'd need to plant absolutely massive amounts of trees to put a dent into the trillion tonnes of CO2 we've released in the last 150 years.

- twic 8y agoThere's a lower-tech way to get algae on board - feed them the micronutrients they're limited by in the ocean, which is mostly iron: https://en.wikipedia.org/wiki/Ocean_fertilization https://en.wikipedia.org/wiki/Ocean_fertilization https://en.wikipedia.org/wiki/Iron_fertilization https://en.wikipedia.org/wiki/Iron_fertilization
