This is a good video that demonstrates the charcoal retort with experimentation. I still think Turtle has a better design.

I'm not fond of this one at all. It basically is a video showing that anyone can make char and help prevent global warming. Good message, right? Nope. Unfortunately, they start out showing a fire starting in some tall grasses. Then it shows a drum full of what you'd expect to see at the end of a large bonfire party. Basically, it's ash with some small pieces of char intermixed.

(the music sucks too)

Official Biochar Tutorial Video
07:24 From: yujm7
This one is great! It's basically an instructional video that describes the process of making char at home using a pit fire and a big metal drum (sealed). The person doing it obviously has a good basic understanding of the science surrounding pyrolysis, physics, and engineering.

Another homemade retort video. Good.

Terra Preta Potato
Not recommended. It's a 12 second video scanning several raised beds. (with some hand drumming in the background)

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
