For a while AltaVista was for sure the most relevant search engine. Like all the others, they evolved by chasing the easiest dollar. Front page ads, paid for results, etc. Small minded stuff.

Google on the other hand took the long view, they kept the front page clean, kept the search results pure, and kept the advertising in check.

Chop down two trees, burn one to heat the other in low oxigen, this is a carbon neutral activity. Now take that biochar and bury it deep in the earth, or use it to condition the soil.

Plant two trees and let them soak up carbon.

I don't see any thermodynamic paradox there.

You could just bury trees, but I think the idea is the charcoal doesn't degrade back to carbon dioxide as quickly.

I think you would fire the furnace with a carbon neutral source, like wood. I think you would fire it with the very vegetation that you are carbonizing. I think they just restrict the amount of air they let in to the chamber.

Also I believe the proposed solution is to apply the char to soil to condition it.

I did a quick google of "pyrolysis carbon sequestration" and then "biochar"

I would say that most of the carbon sequestration ideas I have heard of sound much more crazy than pyrolysis of vegetation.

Personally, I would never support carbon sequestration anyway. I would say I am against purposeful human intervention of climate. If we have messed things up so far by accident or out of ignorance, imagine how bad things will be when we mess with climate for politics.

I heard an idea that seems too simple and cheap to actually ever try but, if we do ever need to sequester carbon from the atmosphere, the proposed solution is to cut the trees and convert them to charcoal by pyrolysis, then bury the charcoal, of course plant new trees and repeat.
