So is there any advantage compared to saline aquifers in CCS? Is there a nice way to capture atmospheric carbon CO2 into raw carbon like in charcoal?

Nature does this for us. Plants take atmospheric CO2 and make solid carbon containing material. So then you can convert it to charcoal and then store it. Some good candidates would be yard waste, corn stover, fast growing trees.

Fascinating! This reminds me very much of your earlier work, pointing out the science of the world around us. Good job.

But Cody don't you know the world is only 5000 years old? :P

I love the way you think. But I have something to think about. Yes, carbon can be taken out of the cycle and locked a way. But as a question, would plan wood be as effective? To make charcoal we have to use energy in some form, you used plant material to burn for energy which releases some CO2. So would it be better to use charcoal or wood buried deep to stop bacteria from breaking wood down to carbon compounds plus carbon dioxide? That would take some extended experimentation to determine which is the most effective means of carbon sequestration.

I remember asking this exact question way back on your first biochar video, i think i said "what's the purpose of making the biochar" and one of your responses was "because it keeps the carbon in the ground for a long time" really cool to see an example of just how long it can last (and see the question answered in video form)

Plain wood would technically be more effective (assuming it isn't aerobically metabolized), but biochar has knock-on benefits that help incentivize people to actually put it in the soil.

Well that interesting must of sequestered a lot of CO2 if it is 20,000 years Old.

How odd. I was watching videos on BioChar last night. I was wondering if its possible to make BioChar using electricity ( or even focussing the sun onto a container ), rather than having an initial fire to heat things up. Eg. big electirc heating element in a can with the wood. Then use the wood gas to progress the process. For every Kg of Carbon captured, how much is lost as Co2. And how does this compare to the methane and other gasses that would have been generated through composting?

Thanks for teaching

If the electricity is coming from coal or oil, then it's kind of defeating the purpose. Solar, wind, hydro, burning it, all things that would probably have a net positive effect (assuming production of materials etc etc). Keeping the carbon underground to start off with is the most important part, so burning it and chucking it back there is still better than it being on the surface on theory

I think this is the most compelling of subjects, given the state of climate change right now. I would love to see Cody engineer a biochar process that doesn't involve open-burning and measure the efficiency and efficacy of different attempts.
